The One Thing EVERYONE Must Know About the Dev Funding Plan: IT'S COMPLETELY FREE.

sigh I get so tired of having to stop working to put out a post explaining issues. If anyone else wants to join in I could use help. (actually I've seen Jonald F. do this before too, so thanks JF!)
Things are bad when even developers don't understand what's going on. So I'll try to clearly explain an important point on the Dev Funding Plan (DFP from now on) for the community: it's completely free. Yet we still get panicked posts saying Please Save Us from the TAX!!! Somebody Help!
You may be for or against the DFP, but either way please at least understand what you're forming an opinion on.
Let's start from the beginning. We know Bitcoin works on blocks and block coin rewards. The block reward, which started at 50 coins per block, and cuts in half approximately every 4 years, serves two purposes: it's a fair way to bring coins into circulation, but more importantly it provides security for the network.
For simplicity, please think of "security" as being measured in power bars. When the network first started, with just Satoshi and Hal Finney, there was 1 power bar. This power bar was made up of the electricity their combined computer hardware used to find blocks. They were the first miners. Bitcoin uses a difficulty level to adjust how hard or easy it is to find blocks. This level is important for a key reason: we want the inflation rate of coins (how fast they come into circulation) to stay about the same, regardless how many miners (computing power) suddenly comes online. If the difficulty is set at super easy, but suddenly a super computer comes online that computer can gobble up thousands of coins in minutes if not seconds, creating massive rapid inflation. So the first thing to understand is that due to the Difficulty Level Adjustment the rate of coins coming into circulation will always stay about the same, regardless how many miners join or leave the network.
Getting back to power bars. So the point of Bitcoin is there is no center, no fixed authority. The problem is we still need a decision made about which chain is valid. This is where proof-of-work comes in. Satoshi's fairly brilliant solution to a consensus decision, with no leader, was to simply look for the longest chain (technically the chain with most hashing work). The reasoning was: as there are far more ordinary people than there are governments and dictators a Bitcoin supported by the all the world's people should always be able to muster more hashrate than even rich governments.
So Bitcoin began and people saw the brilliance: even with a weak power bar level of 1 (a couple computers), Bitcoin was safe from 51% attacks and attacking govs competing for control of the chain because a super low hashrate meant Bitcoin wasn't popular and govs wouldn't bother paying attention. By the time Bitcoin was big enough for govs to worry about attacking it should also have so many participants the power bar level would be far higher, providing strong defense.
Let's say the ideal power bar level is 50,000. At this level no government on earth has enough resources to beat the grassroots network. We hear people brag about how much security BTC has. However, the marketcap for all of BTC is about $160B. Countries like the U.S. and China have GDP measured in many trillions; a trillion is 1,000 billion. Does 160B really seem untouchable? For numeric comparison the main U.S. federal food assistance program cost the government $70B in 2016, representing about 2% of the budget. So the entirety of the BTC market cap is about twice the size of one welfare program, representing 2% of the overall budget. Where should we place the current security power bars if we want guaranteed safety from a determined U.S. gov? If 50,000 is guaranteed safe we're far from it. I'd say BTC is more like 5,000. That's still pretty decent.
Of course, BCH split from BTC... and didn't carry over all the miners and accompanying security. That's not an immediate concern because if BTC isn't on government's radar yet BCH sure isn't. However, that doesn't mean BCH doesn't need security from hostile forces. It's still a valuable network and needs defenses. Where would we put power bars for BCH? If BTC is 5,000 and BCH only has 3% of that hashrate then BCH has just 150. That's it.
How the Developer Funding Plan Works
Back to the DFP. What this says is as a community we agree to break off a piece of the block reward and instead of giving 100% to miners we give a small percent to developers. If each block is 10 coins and the price is $300 then winning a block means winning $3,000. Of course that's not all profit because miners have electricity and other expenses to pay before calculating profit. So if we reduce the portion of the miner reward by 10% so they get just 9 coins per block yet the price stays the same what happens? It means miners receive $2,700 for the same effort. We've just made it more expensive to mine BCH from the point of view of miners. What would any miner then rationally do? Seek profitability elsewhere if available. Suddenly BTC SHA256 hashing looks slightly more attractive so they'll go there. Hashrate leaves BCH and goes to BTC, but the key important point is BOTH chains have a difficulty adjustment algorithm which adjusts to account for rising or lowering miners overall, which keeps the coin inflation rate steady. This means BTC total hashrate rises (more miners compete for BTC) and its Difficulty Level rises accordingly, so the same rate of BTC pumps out; on BCH total hashrate falls (less miners compete for BCH) and its Difficulty falls, so the same rate of BCH pumps out. Inflation remains about the same on both coins so the price of both coins doesn't change any, beyond what it normally does based on news/events etc.
So what difference is there? The difference is total network security. Hashrate totals have changed. BTC gains more miner securing hashrate while BCH loses it. So BTC goes from 5,000 to say 5,100 power bars. BCH goes from about 150 to 140.
Does any of that matter in the grand scheme of things? Not in the slightest. Part of the reason is due to our emergency circumstances with BCH we had to rework our security model. Our primary defense is an idea I came up with, which BitcoinABC implemented, saying it's not sheer hashpower that dictates what chain we follow. We won't replace a chain we're working on if a new one suddenly appears if it means changing more than 10 blocks deep of history. This prevents all the threatening hashrate hanging over our heads from mining a secret chain and creating havoc unleashing it causing 10+ confimed txs to be undone, while exchanges, gambling sites etc. have long since paid out real world money.
Switching $6M worth of block rewards from mining to devs just means we lose a bit of hashrate security, while we gain those funds for development. Nothing more. Nobody holding BCH pays in the form of inflation or any other way. It costs literally NOTHING BECAUSE The block reward is ALREADY ALLOCATED. It will EITHER go 100% to mining security if we do nothing, or go to both miners and devs if the plan is put into effect. Hopefully this helps.
:)
TL;DR: we switch security which we don't really need, for developer funding which we do.

AN INTRODUCTION TO DIGIBYTE

DigiByte

What are cryptocurrencies?
Cryptocurrencies are peer to peer technology protocols which rely on the block-chain; a system of decentralized record keeping which allows people to exchange unmodifiable and indestructible information “coins,” globally in little to no time with little to no fees – this translates into the exchange of value as these coins cannot be counterfeit nor stolen. This concept was started by Satoshi Nakamoto (allegedly a pseudonym for a single man or organization) whom described and coded Bitcoin in 2009.
What is DigiByte?
DigiByte (DGB) is a cryptocurrency like Bitcoin. It is also a decentralized applications protocol in a similar fashion to Neo or Ethereum.
DigiByte was founded and created by Jared Tate in 2014. DigiByte allows for fast (virtually instant) and low cost (virtually free) transactions. DigiByte is hard capped at 21 billion coins which will ever be mined, over a period of 21 years. DigiByte was never an ICO and was mined/created in the same way that Bitcoin or Litecoin initially were.
DigiByte is the fastest UTXO PoW scalable block-chain in the world. We’ll cover what this really means down below.
DigiByte has put forth and applied solutions to many of the problems that have plagued Bitcoin and cryptocurrencies in general – those being:
We will address these point by point in the subsequent sections.
The DigiByte Protocol
DigiByte maintains these properties through use of various technological innovations which we will briefly address below.
Why so many coins? 21 Billion
When initially conceived Bitcoin was the first of a kind! And came into the hands of a few! The beginnings of a coin such as Bitcoin were difficult, it had to go through a lot of initial growth pains which following coins did not have to face. It is for this reason among others why I believe Bitcoin was capped at 21 million; and why today it has thus secured a place as digital gold.
When Bitcoin was first invented no one knew anything about cryptocurrencies, for the inventor to get them out to the public he would have to give them away. This is how the first Bitcoins were probably passed on, for free! But then as interest grew so did the community. For them to be able to build something and create something which could go on to have actual value, it would have to go through a steady growth phase. Therefore, the control of inflation through mining was extremely important. Also, why the cap for Bitcoin was probably set so low - to allow these coins to amass value without being destroyed by inflation (from mining) in the same way fiat is today! In my mind Satoshi Nakamoto knew what he was doing when setting it at 21 million BTC and must have known and even anticipated others would take his design and build on top of it.
At DigiByte, we are that better design and capped at 21 billion. That's 1000 times larger than the supply of Bitcoin. Why though? Why is the cap on DigiByte so much higher than that of Bitcoin? Because DigiByte was conceived to be used not as a digital gold, nor as any sort of commodity, but as a real currency!
Today on planet Earth, we are approximately 7.6 billion people. If each person should want or need to use and live off Bitcoin; then equally split at best each person could only own 0.00276315789 BTC. The market cap for all the money on the whole planet today is estimated to have recently passed 80 trillion dollars. That means that each whole unit of Bitcoin would be worth approximately $3,809,523.81!
$3,809,523.81
This is of course in an extreme case where everyone used Bitcoin for everything. But even in a more conservative scenario the fact remains that with such a low supply each unit of a Bitcoin would become absurdly expensive if not inaccessible to most. Imagine trying to buy anything under a dollar!
Not only would using Bitcoin as an everyday currency be a logistical nightmare but it would be nigh impossible. For each Satoshi of a Bitcoin would be worth much, much, more than what is realistically manageable.
This is where DigiByte comes in and where it shines. DigiByte aims to be used world-wide as an international currency! Not to be hoarded in the same way Bitcoin is. If we were to do some of the same calculations with DigiByte we'd find that the numbers are a lot more reasonable.
At 7.6 billion people, each person could own 2.76315789474 DGB. Each whole unit of DGB would be worth approximately $3,809.52.
$3,809.52
This is much more manageable and remember in an extreme case where everyone used DigiByte for everything! I don't expect this to happen anytime soon, but with the supply of DigiByte it would allow us to live and transact in a much more realistic and fluid fashion. Without having to divide large numbers on our phone's calculator to understand how much we owe for that cup of coffee! With DigiByte it's simple, coffee cost 1.5 DGB, the cinema 2.8 DGB, a plane ticket 500 DGB!
There is a reason for DigiByte's large supply, and it is a good one!
Decentralisation
Decentralisation is an important concept for the block-chain and cryptocurrencies in general. This allows for a system which cannot be controlled nor manipulated no matter how large the organization in play or their intentions. DigiByte’s chain remains out of the reach of even the most powerful government. This allows for people to transact freely and openly without fear of censorship.
Decentralisation on the DigiByte block-chain is assured by having an accessible and fair mining protocol in place – this is the multi-algorithm (MultiAlgo) approach. We believe that all should have access to DigiByte whether through purchase or by mining. Therefore, DigiByte is minable not only on dedicated mining hardware such as Antminers, but also through use of conventional graphics cards. The multi-algorithm approach allows for users to mine on a variety of hardware types through use of one of the 5 mining algorithms supported by DigiByte. Those being:
Please note that these mining algorithms are modified and updated from time to time to assure complete decentralisation and thus ultimate security.
The problem with using only one mining algorithm such as Bitcoin or Litecoin do is that this allows for people to continually amass mining hardware and hash power. The more hash power one has, the more one can collect more. This leads to a cycle of centralisation and the creation of mining centres. It is known that a massive portion of all hash power in Bitcoin comes from China. This kind of centralisation is a natural tendency as it is cheaper for large organisations to set up in countries with inexpensive electricity and other such advantages which may be unavailable to the average miner.
DigiByte mitigates this problem with the use of multiple algorithms. It allows for miners with many different kinds of hardware to mine the same coin on an even playing field. Mining difficulty is set relative to the mining algorithm used. This allows for those with dedicated mining rigs to mine alongside those with more modest machines – and all secure the DigiByte chain while maintaining decentralisation.
Low Fees
Low fees are maintained in DigiByte thanks to the MultiAlgo approach working in conjunction with MultiShield (originally known as DigiShield). MultiShield calls for block difficulty readjustment between every single block on the chain; currently blocks last 15 seconds. This continuous difficulty readjustment allows us to combat any bad actors which may wish to manipulate the DigiByte chain.
Manipulation may be done by a large pool or a single entity with a great amount of hash power mining blocks on the chain; thus, increasing the difficulty of the chain. In some coins such as Bitcoin or Litecoin difficulty is readjusted every 2016 blocks at approximately 10mins each and 2mins respectively. Meaning that Bitcoin’s difficulty is readjusted about every two weeks. This system can allow for large bad actors to mine a coin and then abandon it, leaving it with a difficulty level far too high for the present hash rate – and so transactions can be frozen, and the chain stopped until there is a difficulty readjustment and or enough hash power to mine the chain. In such a case users may be faced with a choice - pay exorbitant fees or have their transactions frozen. In an extreme case the whole chain could be frozen completely for extended periods of time.
DigiByte does not face this problem as its difficulty is readjusted per block every 15 seconds. This innovation was a technological breakthrough and was adopted by several other coins in the cryptocurrency environment such as Dogecoin, Z-Cash, Ubiq, Monacoin, and Bitcoin Gold.
This difficulty readjustment along with the MultiAlgo approach allows DigiByte to maintain the lowest fees of any UTXO – PoW – chain in the world. Currently fees on the DigiByte block-chain are at about 0.0001 DGB per transaction of 100 000 DGB sent. This depends on the amount sent and currently 100 000 DGB are worth around $2000.00 with the fee being less than 0.000002 cents. It would take 500 000 transactions of 100 000 DGB to equal 1 penny’s worth. This was tested on a Ledger Nano S set to the low fees setting.
Fast transaction times
Fast transactions are ensured by the conjunctive use of the two aforementioned technology protocols. The use of MultiShield and MultiAlgo allows the mining of the DigiByte chain to always be profitable and thus there is always someone mining your transactions. MultiAlgo allows there to a greater amount of hash power spread world-wide, this along with 15 second block times allows for transactions to be near instantaneous. This speed is also ensured by the use DigiSpeed. DigiSpeed is the protocol by which the DigiByte chain will decrease block timing gradually. Initially DigiByte started with 30 second block times in 2014; which today are set at 15 seconds. This decrease will allow for ever faster and ever more transactions per block.
Robust security + The Immutable Ledger
At the core of cryptocurrency security is decentralisation. As stated before decentralisation is ensured on the DigiByte block chain by use of the MultiAlgo approach. Each algorithm in the MultiAlgo approach of DigiByte is only allowed about 20% of all new blocks. This in conjunction with MultiShield allows for DigiByte to be the most secure, most reliable, and fastest UTXO block chain on the planet. This means that DigiByte is a proof of work (PoW) block-chain where all transactional activities are stored on the immutable public ledger world-wide. In DigiByte there is no need for the Lightning protocol (although we have it) nor sidechains to scale, and thus we get to keep PoW’s security.
There are many great debates as to the robustness or cleanliness of PoW. The fact remains that PoW block-chains remain the only systems in human history which have never been hacked and thus their security is maximal.
For an attacker to divert the DigiByte chain they would need to control over 93% of all the hashrate on one algorithm and 51% of the other four. And so DigiByte is immune to the infamous 51% attack to which Bitcoin and Litecoin are vulnerable.
Moreover, the DigiByte block-chain is currently spread over 200 000 plus servers, computers, phones, and other machines world-wide. The fact is that DigiByte is one of the easiest to mine coins there is – this is greatly aided by the recent release of the one click miner. This allows for ever greater decentralisation which in turn assures that there is no single point of failure and the chain is thus virtually un-attackable.
On Chain Scalability
The biggest barrier for block-chains today is scalability. Visa the credit card company can handle around 2000 transactions per second (TPS) today. This allows them to ensure customer security and transactional rates nation-wide. Bitcoin currently sits at around 7 TPS and Litecoin at 28 TPS (56 TPS with SegWit). All the technological innovations I’ve mentioned above come together to allow for DigiByte to be the fastest PoW block-chain in the world and the most scalable.
DigiByte is scalable because of DigiSpeed, the protocol through which block times are decreased and block sizes are increased. It is known that a simple increase in block size can increase the TPS of any block-chain, such is the case with Bitcoin Cash. This is however not scalable. The reason a simple increase in block size is not scalable is because it would eventually lead to some if not a great amount of centralization. This centralization occurs because larger block sizes mean that storage costs and thus hardware cost for miners increases. This increase along with full blocks – meaning many transactions occurring on the chain – will inevitably bar out the average miner after difficulty increases and mining centres consolidate.
Hardware cost, and storage costs decrease over time following Moore’s law and DigiByte adheres to it perfectly. DigiSpeed calls for the increase in block sizes and decrease in block timing every two years by a factor of two. This means that originally DigiByte’s block sizes were 1 MB at 30 seconds each at inception in 2014. In 2016 DigiByte increased block size by two and decreased block timing by the same factor. Perfectly following Moore’s law. Moore’s law dictates that in general hardware increases in power by a factor of two while halving in cost every year.
This would allow for DigiByte to scale at a steady rate and for people to adopt new hardware at an equally steady rate and reasonable expense. Thus so, the average miner can continue to mine DigiByte on his algorithm of choice with entry level hardware.
DigiByte was one of the first block chains to adopt segregated witness (SegWit in 2017) a protocol whereby a part of transactional data is removed and stored elsewhere to decrease transaction data weight and thus increase scalability and speed. This allows us to fit more transactions per block which does not increase in size!
DigiByte currently sits at 560 TPS and could scale to over 280 000 TPS by 2035. This dwarfs any of the TPS capacities; even projected/possible capacities of some coins and even private companies. In essence DigiByte could scale worldwide today and still be reliable and robust. DigiByte could even handle the cumulative transactions of all the top 50 coins in coinmarketcap.com and still run smoothly and below capacity. In fact, to max out DigiByte’s actual maximum capacity (today at 560 TPS) you would have to take all these transactions and multiply them by a factor of 10!
Oher Uses for DigiByte
Note that DigiByte is not only to be used as a currency. Its immense robustness, security and scalability make it ideal for building decentralised applications (DAPPS) which it can host. DigiByte can in fact host DAPPS and even centralised versions which rely on the chain which are known as Digi-Apps. This application layer is also accompanied by a smart contract layer.
Thus, DigiByte could host several Crypto Kitties games and more without freezing out or increasing transaction costs for the end user.
Currently there are various DAPPS being built on the DigiByte block-chain, these are done independently of the DigiByte core team. These companies are simply using the DigiByte block-chain as a utility much in the same way one uses a road to get to work. One such example is Loly – a Tinderesque consensual dating application.
DigiByte also hosts a variety of other platform projects such as the following:
The DigiByte Foundation
As previously mentioned DigiByte was not an ICO. The DigiByte foundation was established in 2017 by founder Jared Tate. Its purpose is as a non-profit organization dedicated to supporting and developing the DigiByte block-chain.
DigiByte is a community effort and a community coin, to be treated as a public resource as water or air. Know that anyone can work on DigiByte, anyone can create, and do as they wish. It is a permissionless system which encourages innovation and creation. If you have an idea and or would like to get help on your project do not hesitate to contact the DigiByte foundation either through the official website and or the telegram developer’s channel.
For this reason, it is ever more important to note that the DigiByte foundation cannot exist without public support. And so, this is the reason I encourage all to donate to the foundation. All funds are used for the maintenance of DigiByte servers, marketing, and DigiByte development.

Hello,
I hope you’ve enjoyed my article, I originally wrote this for the reddit sub-wiki where it generally will most likely, probably not, get a lot of attention. So instead I've decided to make this sort of an introductory post, an open letter, to any newcomers to DGB or for those whom are just curious.
I tried to cover every aspect of DGB, but of course I may have forgotten something! Please leave a comment down below and tell me why you're in DGB? What convinced you? Me it's the decentralised PoW that really convinced me. Plus, just that transaction speed and virtually no fees! Made my mouth water!

Q1:- What is SpockChain & its Current Progress? What are the Problems SpockChain trying to solve?

Ans:- Spock has been launched its mainnet on 8/13 2019, it’s the first public blockchain support Solidity smart contract with PoC consensus. In the last month, we have achieved several goals: 1.launched the mainnet, 2.been listed on 6 exchanges, and also Spock has won the voting competition for free list on MXC. 3. Spockpool is online to help small miners to union their capacity and get share of the mining reward. Spock is building a decentralized application network with PoC consensus, which is a more cost saving, environment friendly solution for blockchain system. Spock is going to release is first smart contract in the following months.

Q2:- What is the Use-case Of Spok Coin In Your Ecosystem? How can Holders & Investors Generate Rewards Using Spock Platform?

Ans:- In Spock Network, People can publish/run the apps on the network, all the dapps running on the network needs SPOK. and besides PoC consensus, Spock also involves the concept of PoS, which is that miners need to stake some coins to mine the coins, if not, the miner cannot get the 100% of the block reward, so in SpockPool, coin holders can lend the coins to the miners, when miners mined the reward, it can share with the coin holders.

Q3:- What is the Need & Importance Of SpockChain project in Blockchain Industry?

Ans:- First of all, I think PoC consensus will be a serious option besides PoW and PoS in future, and there must be a significant project stands for PoC consensus, currently Burst or BHD maybe the one, but these two projects has a common problem is that they do not have ecosystem, they only created a coin with PoC consensus, that’s too simple to today’s blockchain world. Spock will be the star project in this area not only just created a coin with PoC consensus, but also it supports smart contract, Ethereum dapps, games can be easily migrated to Spock network.

Q4:- What are the Milestones SpockChain has achieved from the starting of this project? What are the Long Term Targets?

Ans:- For the first question, I have answered in the previous one. Like launch the mainnet, got investment from Continue Capital and other token funds, IEO/IGO on the several exchanges, got free list on MXC by won the voting competition, released explorer, dashboard, desktop wallet, Android wallet, and SpockPool, all these things above happens in the last month!!! For the short-term goal, Spock is trying to be the Ethereum with PoC consensus, so for the following 6 month to 1 year, Spock will expand the developer community to increase the dapps/tokens on its network. And also the final goal of Spock is to upgrade the consensus not only store the hash value, but also store documents, music, videos, etc. We’re still working on that part.

Segment 2 Questions

Q5:- What are your major goals to archive in the next 3-4 years? Where can we Spockchain ecosystem in this period? What are your plans to expand and gain more adoption?

Ans:- 1. Spreading the Proof of Capacity consensus, let more people know there is another way of mining to gain. 2. Build the developer economy on Spock Network, on Spock Network, not only smart contract, but a new type of tokens will be supported, which is not like the ERC-20, it’s tokens that generated as the block generated, but the developer can define the tokens generation rules, we call them mining-tokens. 3. Search the new way to upgrade the storage network, to finally achieve the goal that the a decentralized storage network can serve the internet users, that would be a totally new future of blockchain world.

Q6:- As a team member of Spockchain, what is your long-term vision about the industry which Spockchain is working at? Are you afraid someday there will be another project with more innovative technology can replace?

Ans:- I think the infrastructure of Blockchain world today has only two main directions: 1. cross chain Technoledge like Cosmos, Polka-dot. 2. Decentralized storage like IPFS. As long as we're heading to the right direction, we won't get a very bad result, even we have failed, but the way we passed through can be borrowed to other projects, there must be some projects success in this area. I feel confident about the project going and what we have done comparing to the other competitors, as currently so many projects claim that they want to be Ethereum in PoC, but none of the has launched the mainnet except SPOCK.

Q7:- Why Spock Network have Chosen Proof of Capacity Consensus Mechanism ? Any advantage over other consensus?

Ans:- Here is the description in the white paper about advantage of PoC:
Environmental protection: When a mining machine is initialized, the mining cost is relatively small, requiring only a small amount of disk access and a small amount of calculations per block.
• Economy: Many PCs have unused disk space. The marginal cost of using these spaces for mining is small, with immediate rewards and can be used for mining. It is not necessary to consider the cost of electricity as a bitcoin mining machine.
• Equality: Today Bitcoin has become the world of Asics mining machines and large mines, and small-scale investors have struggled to participate in the bitcoin mining ecology, while POC-based mining machines are hardly faced with bitcoin-like The mining machine is constantly updating its iterations so that it is completely eliminated.
• “computing power” sharing: BCH is a BTC hard fork chain, so BTC's proprietary mining machine can also dig BCH, but it can't dig BTC and BCH at the same time, and the POC mechanism can make the hard disk for different chains. The spatial "computing power" data structure is consistent, and these "computing power" can be used to dig assets on these chains at the same time.
I think the value of PoC is under-estimated today, that’s why we want to promote the consensus.

Q8:- What are the competitors of Spock Network? How Spock Network is better than their competitors ?

Ans:- In storage domain, they can be: Filecoin/Storj/Sia/Lambda/Filestorm/Yotta
In PoC consensus domain, there are: Burst/BHD/LHD/Boom/Newbi/Disc
In PoC+Smart contract domain, there are: Spock/Galaxy Network/BSN/EHD
Currently, in a completely decentralized blockchain network, there is no such consensus can distribute the coins as the miners contribute the hard disk and network, all these projects take some trade-off to make that happen except File coin, File coin uses Proof of Replication and Proof of Space-time consensus, that may be an option to solve this problem, but its mainnet has not launched, it would take time to achieve that. The Burst, BHD, and other similar projects only uses PoC consensus to created a mining coin, but the usage and scenario are very limited, it’s not year 2013, you can simply create an alt coin and people will buy it. The PoC consensus needs find some usage and scenario to make the network more solid and strong, the smart contract can be the way. As I listed, all the projects have not launched its mainnet except Spock.

Q9:- How Scalable Spock Network have , How many TPS achieved so far ?

Ans:- Spock has its own advantage about improve TPS, because nodes running in the network has much hard disks and network traffic, basically we can increase the size of block header to increase the TPS, and also we're investigating other ways to improve the TPS.

Q10:- Why the name of Project " SPOCK" . What does it signify about your project?

Ans:- Spock is the leading character of Star Trek, we choose the name to inspire the team to keep exploring the possibility of the blockchain world, sand the slogan of Spock is “live long and prosper”, which is also the hope of the team for the project, nowadays, too many fake mining projects out there, Spock wants to show the honesty and integrity by continually showing the code and improving the project.

Q11:- Followed your whitepaper, Spock has a leaderless PoC protocol, does not use a committee or an authority. How this use for? What benefit does it have for Spock?

Ans:- In the consensus level, there is indeed no such organization can change or control it, just like PoW, when the network needs to upgrade its consensus, the community will join the discussion and the dev team will follow the result of it. That's the spirit of Satoshi and all the early blockchain projects.

Q12:- What is the form of Spock mining? What are the conditions for miner application?

Ans:- To mine spock, you can just use normal computer with several hard dist with plotted files, there are tutorials on thehttps://www.spockchain.org

Q13:- What next technology updating after building a decentralized storage data application network in 2021? Will Spock expand to other areas in long term development?

Ans:- I think after the infrastructure is completed that we will focus on the application ecosystem and adoption of the ecosystem, Spock dev team will continue working on the infrastructure and other scenarios/applications to promote the adoption, I think in a very long time, Spock project will only focus on decentralized storage domain.

Q14:- Does your team have a plan to add DAO module into your project since its its effiency on autonomy, decentralization and transparency?

Ans:- Spock will run DAO mode for autonomy, the Spock team is still working on the details of it.

Q15:- What is the role of Smart Contract in Spock Chain? Does your team have a security system to check the operation of whole project?

Ans:- Smart Contract will be the key feature that distinguish Spock and other projects with PoC consensus, Spock leverages lots of work from Ethereum, so Spock is standing on the shoulders of giants, which potential lower-level security risks can be avoid, and we also have a security team to improve the smart contract, like before you submit your smart contract, there is a service to help to analysis the code to help you avoid some common mistakes.

Q16:- What is Spockchain vision and what's your biggest challenges?

Ans:- Spock is trying to be Ethereum with PoC consensus in a short-term, that goal seems to be very promising as everything goes well so far. Spock’s long-term goal is trying to provide a decentralized storage network for all the internet users, that would be challenging from both technical side and business side.

Q17:- Spockchain looks good but it confuses me that there are so many other Blockchain projects. What should I pay attention in Spockchain to give it the importance it deserves? What are you planning to achieve with your project goal?

Ans:- I think code and time talks, Spock is not a simply ERC-20 token, it’s a mining coin. If you checkout the top 50 projects on CMC, most of them are mining projects, because mining coins are very fair way to distribute the coins. And Spock provides another option for mining, you don’t have to search for low-cost electricity power, you can just set up the mining machines at home to mine the coins. It’s a potential mining way to mine cryptocurrency, if you have mined BTC/ETH, you can have a try about Spock/Burst/BHD, etc.

Q18:- Blockchain projects is not a child play. While creating spok projects, have u for once been discouraged to the extent of wishing to stop since its all about intelligent contract and users poc consensus.

Ans:- Honestly, we do. there is so many hard work to combine the smart contract and poc consensus, but we believe the technology and engineering, and we believe the judgement about the trend of blockchain technology, that's what encourage us to the place we have achieved.

Q19:- How the SpockChain project planning process is ensure? The market needs constant progress of project! How to avoid the spok Project idleness?

Ans:- We're continuously building and expanding the community and miner groups, both online and offline side. currently most miners are from Asia(China mostly),there are only several miners in Europe and US, we do want to spread spok ecosystem across other continents, if anyone in other countries is interested in promoting Spock, please directly contact me!

Q20:- Can anyone run a POC mining and does it require much processing power? Is the cost of POC mining high?

Ans:- Yes, anyone can run a PoC mining, it's electricity power insensitive. the electricity power of each petabytes of a day is only several dolloars, while the cost of a petabytes will be about 30000 dollars.

Q21:- Is POC exploitation cost high? What is it suitable for? What is the number of SPOCK user statistics today? Does SPOCK have a plan to attract users?

Ans:- you can check out the websites, Official website: https://www.spockchain.org Spock Explorer: http://www.spock.network Miner Dashboard: https://dashboard.spock.network

Q22:- What is the function of SPOCK? Are there any benefits to SPOCK holders? How do I earn SPOCK?

Ans:- All the smart contract runs on Spock will cost SPOK, and miners want to mine SPOK will need some amount of SPOCK to stake. You can get the Spock on the exchanges that lists Spock, MXC, Coinex, VB, Bihodl, etc.
Q23:- So What does SPOCK ecosystem include? What all problems SPOCK will solve in Crypto market?
Ans:- Spock is trying to be the Ethereum with PoC consensus, the biggest advantage of PoC consensus is that it saves much electricity than PoW, the “computing power “ is kind of like stored on the hard disk, so the system will be changed to be storage-incentive from computing-incentive., that would change the way of crypto mining, and also Spock introduced the Solidity smart contract in such blockchain system, which make the developers easily migrated their dapps from Ethereum to Spock.
Q24:- How Proof of Capacity Consensus works in SPOCK Chain?
Ans:- The core function about PoC in Spock is just like the PoC consensuse implementation in Burst project, which is the first project uses PoC consensus since year 2014. In high level, the PoC consensus is an algorithm which preprocessing the hash calculation by plotting the whole hard disk with hash values, when generating a new block, the node will scan the hard disk and find the most proper "answer" in the disks and submit to the network, the node submitted the most proper answer will get the mining reward.
Q25:- How Spock and other storage platform i.e. Google drive are different and what benefits you have over them?
Ans:- Basically Spock and Google drive is totally different, as Spock today only stores consensus data. I’d like to talk about the overall differences between decentralized storage and centralized storage services.
Traditional centralized storage platforms generally use cloud storage. Most of the data is stored on a few cloud platforms, which leads to data accumulation and serious centralization problems. There are also problems including higher cost, slower transfer rate, and lower data security. The decentralized storage application platform encrypts and distributes data through a distributed network, meaning that no data other than the data owner can access the data, ensuring security.
And another core feature is the protection of private data, the open decentralized platform can do better, just like the assets of the cryptocurrency, the ownership of the assets represented by the private key, in the decentralized storage platform The private key can represent the disposition and access rights of the data.
Q26:- What do you think is the biggest problem Spock Network will solve which is not solved by other projects yet and why is the problem important to solve?I mean how unique SPOCK Network have?What are the Real world use-cases & utility of SPOK ?
Ans:- 1. I think there are so much projects uses PoC consensus, but all of them are lack of economy, with smart contract feature, Spock will be the first public blockchain support Solidity smart contract and with lower energy cost for running.
2. First of all, the usage of the smart contract will cost SPOK , and the mining policy makes miners need to stake SPOK to mine. and other industry is trying to looking for the adoption of Spock as it's a storage network with smart contract, there is very much possibility we can explore.
Q27:- Will the mining on SPOCK CHAIN Platform Profitablein bear Market? In which form will the output of Mining?
Ans:- The PoC mining is the most anti-bear-marketing mining way I think, you know when BTC comes to 15000$, Bitmain miners S9’s price goes to 4000$, this year, when the BTC prices comes to 3000$, S9’s price is less than 100$. Miners takes all the risk for the price going down, because the manufactory of BTC/BCH miner machines are limited and united. While the miner machines of PoC consensus does not have that problem, because the supplyment of hard disk is very sufficient, and the price is very stable.
Q28:- Why does Spockchain use POC and not POW or POS? Are there advantages of POC compared to POW and POS? There are many projects using POC such as: BHD, BSN, .... Is Spockchain different from these projects?
Ans:- 1. The main issue of PoW is that it’s energy waste and it limits the miners nowadays, people basically cannot mine any PoW coins at home, they have to buy equipments and send them to some place with lower-cost electricity power which makes difficulty to ordinary people. The biggest advantage of PoC is that it save tremendous money on electricity power.
The PoS basically cost nothing to generate new coins, I think it would also be problem for the price, as people get the coins so easy, they may not value it.
2.I have a list about PoC coins (the list is growing..) I do want to share some opinion about all these PoC projects including Spock.
I categorized the projects into two:
PoC consensus only: Burst/BHD/LHD/DISC/Boom/Newbi/Lava
PoC consensus + Smart Contract: Spock/BSN/Galaxy Network/EHD
For the projects in first list, these projects only talks about consensus and coins, but lack of usage and scenarios.
For the second lines, please check out and compare all the projects, none of them have launched the mainnet except SPOCK, while those projects started to mine with ERC-20 tokens.
I think the chanlledge is lack of acknowledge of Proof of Capacity consensus all over the world, the PoC introduce a new way to mine cryptocurrency, currently, Spock has a lot of miners in China, but not much in other places, spreading the consensus takes time. I think code/products shows hoesty and integrity, we have lots of plan to develop the network, while so many projects with similar ideas still runs on ERC-20, with time goes by, people will distinguish that.
Q29:- Currently, what are risks affecting the Spockchain project? In order to develop project in long term and attract investors, which method do you use to manage, minimize the negative impact of risks? I mean that, what are the risks and how do you deal with them?
Ans:- do you mean cheat when mining? First of all, you cannot have fundamental issue on the consensus basis, then if there is some way for smart miners to cheat to gain more rewards, we can update the full node program which can prevent the cheat. I think if that happen, community will support us to update the nodes in the network.
Q30:- How can a cryptocurrency mining algorithm be detected and prevented? What makes them so difficult to detect?
Ans:- According to the stats, 2016-2018, the supply of hard disk is 1.2billion, if we count as average capacity 4T, which is 48,000,000P, while currenlty the largest network with PoC consensus is BHD, which has capacity at about only 1500P.

Are New Bitmains’ ASIC Devices Profitable?

Are New Bitmains’ ASIC Devices Profitable?
You might have heard that Bitmain has announced the next generation Antminer ASIC mining devices.These devices (S17+ and T17+) are expected to deliver higher hash rates while keeping relatively comparable energy consumption rates.
Bitmain stays true to itself and regularly releases new hardware on its Antminer line. Usually, their products are the top ones on the market in terms of hash rate, but it’s always just a matter of time until the competition catches up.

https://preview.redd.it/131m5wm3wgu31.png?width=1920&format=png&auto=webp&s=f96ef5ad457b46ec058849117432921c2da4821e
Also, there is another problem with third-parties pre-empting the devices and then reselling them at a much higher price. One can only hope that this time Bitmain manages to deliver a reasonable amount of devices.
This time, Bitmain is releasing two devices: S17+ with a hashrate of 72 TH/s that is consuming around 2,920 watts of power and an ‘economy class’ T17+ with 64 TH/s and 3,200 watts of power consumption.

What’s the Profit?

So how profitable it is to run one of these devices considering the current state of market? According to Blockonomi’s calculations, S17+ is profitable to operate, but if you’re hoping for big wins, that’s not going to happen. Assuming an electricity price of $0.10 per kilowatt and running your device for 24/7 for an entire year (no change in difficulty considered) you can expect to earn about half a bitcoin. However at the end of the day, it all comes down to electricity costs.
As for T17+, you could get about 0.45156798 BTC, at the cost of $2,8 in electricity fees.

Is it worth it?

Like everything in the crypto space, this is very hard to predict.
Once these devices hit the market, they will set the hash rate standard, which means increasing network difficulty and lowering the efficiency of the hardware.
Moreover, the bitcoin prices have been bouncing around the $7,500 to $8,000 mark for a while, and if your goal is to sell all of the bitcoin you’ve mined right away, you would probably be able just to cover the equipment and electricity cost after one year but nothing more.
If you are determined that ASIC mining is your thing, it can be a good idea to buy one of these devices but avoid purchasing it from the resellers.

The Bottom Line

No matter which equipment you decide to go with, you can use CoinFly to increase your profits.
We offer you an opportunity to mine the most profitable currency and optimize the mining profit automatically: once the situation on the market changes, the system will just switch to mining the most profitable coin, thus, you will have the possibility to tune your hardware online to achieve optimal performance.

Trying to calculate bitcoin mining profitability but im not getting it right. How can i do it with these hardware specs?

PC specs:
nvidia geforce 830m
intel core i7-5500U CPU 2.40GHz
*No costs with energy
I tried to calculate on online tools but i must be doing something wrong because all of them are giving me wrong values (there are some fields that i dont know their meaning like Hashing Power, Polling Fee, Bitcoin Difficulty, Hash Rate, Block Reward, etc... )

Bitcoin Mining Power Hits New High as Half a Million New ASICs Go Online

Bitcoin Mining Power Hits New High as Half a Million New ASICs Go Online


News by Coindesk: Wolfie Zhao
The computing power dedicated to mining bitcoin has hit yet another new high, suggesting that more than 600,000 powerful new machines may have come online in the last three months.
According to data from crypto mining pool BTC.com, bitcoin’s two-week average hash rate has crossed another major threshold, reaching 85 exahashes per second (EH/s) around 19:00 UTC last Friday. Meanwhile, mining difficulty also adjusted to a new record of nearly 12 trillion.
Notably, both figures have jumped 60 percent since June 14, the data shows.
Bitcoin’s mining difficulty — a measure of how hard it is to create a block of transactions — adjusts after 2,016 blocks, or roughly every two weeks. This is to ensure the time to produce a block remains around 10 minutes, even as the amount of hashing power, deployed by machines around the globe competing to win freshly minted bitcoins, fluctuates.
Several new models of application-specific integrated circuit (ASIC) miners hit the market over the summer, with an average hashing power around 55 tera hashes per second (TH/s).
Assuming all of the 35 EH/s of new hashing power added since mid-June came from these top-of-the-line models, a back-of-the-envelope calculation suggests that more than half a million such machines have connected to the bitcoin network. (1 EH/s =1 million TH/s)

Billion-dollar business?

These powerful ASIC miners, made by major manufacturers such as Bitmain, Canaan, InnoSilicon and MicroBT, are priced from $1,500 to $2,500 each. So if more than half a million of them were delivered, as estimated above, the leading miner makers could have made $1 billion in revenue over the past three months.
Bitcoin’s spiking hash rate and difficulty are in line with the soaring price since earlier this year, which led to increasing demand for mining equipment that has significantly outstripped supply. It’s also in part thanks to the rainy summer season in southwestern China which resulted in cheap, abundant hydroelectric power.
Further, there has also been a growing interest in Russia’s Eastern Siberia region, where the Brastsk hydropower station built in the Cold War era has been utilized to power mining farms that are estimated to account for almost 10 percent of the total computing power on the bitcoin network.
Miners in China estimated earlier this year that bitcoin’s average hash rate in the summer would break the level of 70 EH/s, which happened in August.
As such, major miner manufacturers have already sold out equipment that is due for shipment until the end of the year with customers placing pre-orders three months in advance.
TokenInsight, a startup that focuses on analysis of crypto trading and mining activities, said in a report published Friday that additional supplies of miners are expected to hit the market in the coming months.
“Following the drastic increase in bitcoin’s price, the bitcoin mining market saw significant inflation in Q2 2019. Most of the miners from various manufacturers were in serious shortage and pre-orders submitted in Q2 and Q3 are to be delivered by the end of the year,” the report states.
Therefore, the firm estimates mining difficulty will maintain its growth momentum to reach 15 trillion by the end of the year — with bitcoin’s average total hashing power crossing the threshold of 100 EH/s for the first time in its history.

What's the difference between Litcoin and Bitcoin?

In 2009, Satoshi Nakamoto launched bitcoin as the world’s first cryptocurrency. The code is open source, which means it can be modified by anyone and freely used for other projects. Many cryptocurrencies have launched with modified versions of this code, with varying levels of success.
Litecoin was announced in 2011 with the goal of being the ‘silver’ to bitcoin’s ‘gold’. At the time of writing, Litecoin has the highest market cap of any mined cryptocurrency, after bitcoin.
Here’s our guide to show you the crucial difference between bitcoin and litecoin.
Mining differences
Just like bitcoin, litecoin is a crytocurrency that is generated by mining. Litecoin was created in October 2011 by former Google engineer Charles Lee. The motivation behind its creation was to improve upon bitcoin. The key difference for end-users being the 2.5 minute time to generate a block, as opposed to bitcoin’s 10 minutes. Charles Lee now works for Coinbase, one of the most popular online bitcoin wallets.
ASIC Mining
For miners and enthusiasts though, litecoin holds a much more important difference to bitcoin, and that is its different proof of work algorithm. Bitcoin uses the SHA-256 hashing algorithm, which involves calculations that can be greatly accelerated in parallel processing. It is this characteristic that has given rise to the intense race in ASIC technology, and has caused an exponential increase in bitcoin’s difficulty level.
Litecoin, however, uses the scrypt algorithm – originally named as s-crypt, but pronounced as ‘script’. This algorithm incorporates the SHA-256 algorithm, but its calculations are much more serialised than those of SHA-256 in bitcoin. Scrypt favours large amounts of high-speed RAM, rather than raw processing power alone. As a result, scrypt is known as a ‘memory hard problem‘.
The consequences of using scrypt mean that there has not been as much of an ‘arms race’ in litecoin (and other scrypt currencies), because there is (so far) no ASIC technology available for this algorithm. However, this is soon to change, thanks to companies like Alpha Technologies, which is now taking preorders.
GPU mining
To highlight the difference in hashing power, at the time of writing, the total hashing rate of the bitcoin network is over 20,000 Terra Hashes per second, while litecoin is just 95,642 Mega Hashes per second.
For the time being, ‘state of the art’ litecoin mining rigs come in the form of custom PCs fitted with multiple graphics cards (ie: GPUs). These devices can handle the calculations needed for scrypt and have access to blisteringly fast memory built into their own circuit boards.
There was a time when people could use GPU mining for bitcoin, but ASICs have made this method not worth the effort.
If you are a developer, cryptocurrency investor, or just a curious person and want to invest some time to learn about cryptocurrency visit BTCNEWZ
Transaction differences
The main difference is that litecoin can confirm transactions must faster than bitcoin. The implications of that are as follows:
Transaction speed (or faster block time) and confirmation speed are often touted as moot points by many involved in bitcoin, as most merchants would allow zero-confirmation transactions for most purchases. It is necessary to bear in mind that a transaction is instant, it is just confirmed by the network as it propagates.

News everyone

This is a big announcement for Electroneum. See bottom of this article for the full details of the blockchain tech update.
Some of our community have been worried about our blockchain tech, especially regarding ASIC miners and blockchain flooding. We will cover these below along with the announcement of some exciting major changes to the way our blockchain runs.
ETN Blockchain Update May 30th Monero (who we based our blockchain code on) perform an update approximately every 6 months, and this is a great practice, as it allows them to keep their technology moving forward and introduce new features. We will be following this model and our first major update (also known as a fork) is scheduled to take place at block 307500 which is approximately 10.30am BST on May 30th.
Don’t panic! – Forking explained It’s important for everyone to understand that whilst this is known as a fork, it is very different to Bitcoin forking to bitcoin cash or bitcoin gold. The fork will not result in two currencies, as all the exchanges and pools will update their software in advance of the update block and Electroneum will continue with an updated blockchain.
Time to test and implement The end of May gives our community plenty of time to test and comment on the code changes that we will post on GitHub by Friday 5th of May. It also gives plenty of time for every node owner to update their Electroneum nodes, ready for the update block.
Electroneum divergence from Monero We’ve always planned to move the Electroneum blockchain further towards reaching our goals, which in turn will move us away from Monero’s goals. We chose Monero because they’d written an awesome dynamic blocksize algorithm, but they also have some features that are not critical to Electroneum’s future. In this Electroneum update we’ve started to diverge away from some core Monero functionality. As we move towards a lean, fast blockchain to handle vast numbers of micropayments we need to lose some of the overhead that comes with the privacy of Monero. We are still going to be far more private than Bitcoin or Ethereum (for instance you won’t be able to look at someone else’s wallet balance), but by decreasing some of the privacy features we can fit significantly more transactions into a block, which is critical for our next stage of growth as our corporate partners start to bring on user numbers, and our vendor program starts delivering instant cryptocurrency acceptance into online and physical shops and stores. In short Monero is the best privacy coin in the world, where we need to be the best micropayment system in the world.
ETN Blockchain Tech Update (Details) Anti- ASIC. An ASIC is a computer chip that has been made for a specific task. In this instance the task is to mine the CryptoNight algorithm that Electroneum uses. We are implementing Anti-ASIC code to ensure we have maximum resistance to any network attack that could occur in the future. Limiting mining to GPU’s reduces the chances of a single entity possessing enough hashing power to attempt a 51% network attack. It’s important to note that there is no proof of a 51% network attack having taken place on the Electroneum blockchain. Transfer Fee Increase. There have been a lot of comments about our transfer fee being too low. It is important to our project that the fee remains low, because we are going to be focusing on instant payments and instant micropayments in the real world, and we need fees that are lower than typical debit / credit card fees. However, we have suffered from blockchain flooding so are taking steps to ensure we are resistant to this in the future. We have therefore decided to increase our base fee to 0.1 ETN. This is still a fraction of the cost of transfer of other cryptocurrencies, but still increases the difficulty of flooding by an order of magnitude. Combined with our other updates (below) this will give us more effective resistance to blockchain flooding. Increase block size before penalty. We have been enormously successful and seen some periods with huge amounts of legitimate blockchain transaction traffic. This, combined with blockchain flooding, has meant periods of blockchain delays. By increasing the block size before penalty, miners will be able to scale the blocks faster and get more transactions into a block. This will handle regular transactions and flood transactions, making delays less likely. Combined with the Fee increase this is a significant resistance enhancement to flooding. Disabling of RingCT & Mixin. RingCT was introduced by Monero whose main focus is privacy. Our main focus is bulk transactions for a mass audience, and thus we are disabling some of the privacy features of the blockchain. Disabling some privacy features means we can fit significantly more transactions into each block than with them enabled. This means less wait to get a transaction into a block and a leaner blockchain size. Wallets are still private as we will continue to use a new stealth wallet address for every blockchain transaction so there is still significantly more privacy than with Bitcoin or Ethereum, but considerably less privacy than with a privacy focused coin like Monero. Mempool life to 3 days. During high transactional volumes it is feasible that a transaction can remain in the mempool for 24 hours and reach the current limit. This would mean the transaction is returned to the sender, but that could take up to 7 days. By increasing the mempool life to 3 days (and in conjunction with some of the additional changes) we are ensuring a significant reduction in the possibility of these returned transactions. 2 minute blocks. Blocks are currently mined every minute. We are moving to two minute blocks which will significantly decrease the chance of an orphan block being created. Orphan blocks might contain transactions which will eventually (7 days) be returned or added to another block. Increasing the block time to 2 minutes has ramifications on the block reward which will be modified (see below). Block Reward. We are doubling the block reward to ensure daily ETN block reward remains the same, despite the fact that we are releasing blocks at half the current speed. This means there will be no discernable effect to miners or pools. Reduce difficulty window. Block difficulty window is being reduced. The block difficulty is calculated by looking at the last X blocks. It has come to our attention that by hitting the ETN blockchain with large powered rented hashing power gives the miner an advantage over a short period of time (until the difficulty algorithm catches up with the new hashing rate). We are reducing the difficulty window to reduce the benefit these periodic miners have and to discourage this practice, making the mining process fairer. This should have little or no effect on the difficulty number itself except during the exceptional circumstances described. Thanks for taking the time to read this update! If you are running an Electroneum node remember to update before May 30th. If you are using a pool, ensure you let their telegram or other social channel know that this update is critical and must be applied before May 30th, in advance of block 307500.
Have a great day everyone,

Blockchain Dictionary for Newbies

Blockchain Glossary: From A-Z
51% Attack
When more than half of the computing power of a cryptocurrency network is controlled by a single entity or group, this entity or group may issue conflicting transactions to harm the network, should they have the malicious intent to do so.
Address
Cryptocurrency addresses are used to send or receive transactions on the network. An address usually presents itself as a string of alphanumeric characters.
ASIC
Short form for ‘Application Specific Integrated Circuit’. Often compared to GPUs, ASICs are specially made for mining and may offer significant power savings.
Bitcoin
Bitcoin is the first decentralised, open source cryptocurrency that runs on a global peer to peer network, without the need for middlemen and a centralised issuer.
Block
Blocks are packages of data that carry permanently recorded data on the blockchain network.
Blockchain
A blockchain is a shared ledger where transactions are permanently recorded by appending blocks. The blockchain serves as a historical record of all transactions that ever occurred, from the genesis block to the latest block, hence the name blockchain.
Block Explorer
Block explorer is an online tool to view all transactions, past and current, on the blockchain. They provide useful information such as network hash rate and transaction growth.
Block Height
The number of blocks connected on the blockchain.
Block Reward
A form of incentive for the miner who successfully calculated the hash in a block during mining. Verification of transactions on the blockchain generates new coins in the process, and the miner is rewarded a portion of those.
Central Ledger
A ledger maintained by a central agency.
Confirmation
The successful act of hashing a transaction and adding it to the blockchain.
Consensus
Consensus is achieved when all participants of the network agree on the validity of the transactions, ensuring that the ledgers are exact copies of each other.
Cryptocurrency
Also known as tokens, cryptocurrencies are representations of digital assets.
Cryptographic Hash Function
Cryptographic hashes produce a fixed-size and unique hash value from variable-size transaction input. The SHA-256 computational algorithm is an example of a cryptographic hash.
Dapp
A decentralised application (Dapp) is an application that is open source, operates autonomously, has its data stored on a blockchain, incentivised in the form of cryptographic tokens and operates on a protocol that shows proof of value.
DAO
Decentralised Autonomous Organizations can be thought of as corporations that run without any human intervention and surrender all forms of control to an incorruptible set of business rules.
Distributed Ledger
Distributed ledgers are ledgers in which data is stored across a network of decentralized nodes. A distributed ledger does not have to have its own currency and may be permissioned and private.
Distributed Network
A type of network where processing power and data are spread over the nodes rather than having a centralised data centre.
Difficulty
This refers to how easily a data block of transaction information can be mined successfully.
Digital Signature
A digital code generated by public key encryption that is attached to an electronically transmitted document to verify its contents and the sender’s identity.
Double Spending
Double spending occurs when a sum of money is spent more than once.
Ethereum
Ethereum is a blockchain-based decentralised platform for apps that run smart contracts, and is aimed at solving issues associated with censorship, fraud and third party interference.
EVM
The Ethereum Virtual Machine (EVM) is a Turing complete virtual machine that allows anyone to execute arbitrary EVM Byte Code. Every Ethereum node runs on the EVM to maintain consensus across the blockchain.
Fork
Forks create an alternate version of the blockchain, leaving two blockchains to run simultaneously on different parts of the network.
Genesis Block
The first or first few blocks of a blockchain.
Hard Fork
A type of fork that renders previously invalid transactions valid, and vice versa. This type of fork requires all nodes and users to upgrade to the latest version of the protocol software.
Hash
The act of performing a hash function on the output data. This is used for confirming coin transactions.
Hash Rate
Measurement of performance for the mining rig is expressed in hashes per second.
Hybrid PoS/PoW
A hybrid PoS/PoW allows for both Proof of Stake and Proof of Work as consensus distribution algorithms on the network. In this method, a balance between miners and voters (holders) may be achieved, creating a system of community-based governance by both insiders (holders) and outsiders (miners).
Mining
Mining is the act of validating blockchain transactions. The necessity of validation warrants an incentive for the miners, usually in the form of coins. In this cryptocurrency boom, mining can be a lucrative business when done properly. By choosing the most efficient and suitable hardware and mining target, mining can produce a stable form of passive income.
Multi-Signature
Multi-signature addresses provide an added layer of security by requiring more than one key to authorize a transaction.
Node
A copy of the ledger operated by a participant of the blockchain network.
Oracles
Oracles work as a bridge between the real world and the blockchain by providing data to the smart contracts.
Peer to Peer
Peer to Peer (P2P) refers to the decentralized interactions between two parties or more in a highly-interconnected network. Participants of a P2P network deal directly with each other through a single mediation point.
Public Address
A public address is the cryptographic hash of a public key. They act as email addresses that can be published anywhere, unlike private keys.
Private Key
A private key is a string of data that allows you to access the tokens in a specific wallet. They act as passwords that are kept hidden from anyone but the owner of the address.
Proof of Stake
A consensus distribution algorithm that rewards earnings based on the number of coins you own or hold. The more you invest in the coin, the more you gain by mining with this protocol.
Proof of Work
A consensus distribution algorithm that requires an active role in mining data blocks, often consuming resources, such as electricity. The more ‘work’ you do or the more computational power you provide, the more coins you are rewarded with.
Scrypt
Scrypt is a type of cryptographic algorithm and is used by Litecoin. Compared to SHA256, this is quicker as it does not use up as much processing time.
SHA-256
SHA-256 is a cryptographic algorithm used by cryptocurrencies such as Bitcoin. However, it uses a lot of computing power and processing time, forcing miners to form mining pools to capture gains.
Smart Contracts
Smart contracts encode business rules in a programmable language onto the blockchain and are enforced by the participants of the network.
Soft Fork
A soft fork differs from a hard fork in that only previously valid transactions are made invalid. Since old nodes recognize the new blocks as valid, a soft fork is essentially backward-compatible. This type of fork requires most miners upgrading in order to enforce, while a hard fork requires all nodes to agree on the new version.
Solidity
Solidity is Ethereum’s programming language for developing smart contracts.
Testnet
A test blockchain used by developers to prevent expending assets on the main chain.
Transaction Block
A collection of transactions gathered into a block that can then be hashed and added to the blockchain.
Transaction Fee
All cryptocurrency transactions involve a small transaction fee. These transaction fees add up to account for the block reward that a miner receives when he successfully processes a block.
Turing Complete
Turing complete refers to the ability of a machine to perform calculations that any other programmable computer is capable of. An example of this is the Ethereum Virtual Machine (EVM).
Wallet
A file that houses private keys. It usually contains a software client which allows access to view and create transactions on a specific blockchain that the wallet is designed for.

- Expectations in the field of quantum computer development.
- Quantum resistant blockchains
- Why is it easier to change cryptography for centralized systems such as banks and websites than for blockchain?
- Conclusion
The fact that whatever is registered on a blockchain can’t be tampered with is one of the great reasons for the success of blockchain. Looking ahead, awareness is growing in the blockchain ecosystem that quantum computers might cause the need for some changes in the cryptography that is used by blockchains to prevent hackers from forging transactions.
How would quantum computers pose a threat to blockchain?
First, let’s get a misconception out of the way. When talking about the risk quantum computers could pose for blockchain, some people think about the risk of quantum computers out-hashing classical computers. This, however, is not expected to pose a real threat when the time comes.
This paper explains why: https://arxiv.org/pdf/1710.10377.pdf "In this section, we investigate the advantage a quantum computer would have in performing the hashcash PoW used by Bitcoin. Our findings can be summarized as follows: Using Grover search, a quantum computer can perform the hashcash PoW by performing quadratically fewer hashes than is needed by a classical computer. However, the extreme speed of current specialized ASIC hardware for performing the hashcash PoW, coupled with much slower projected gate speeds for current quantum architectures, essentially negates this quadratic speedup, at the current difficulty level, giving quantum computers no advantage. Future improvements to quantum technology allowing gate speeds up to 100GHz could allow quantum computers to solve the PoW about 100 times faster than current technology.
However, such a development is unlikely in the next decade, at which point classical hardware may be much faster, and quantum technology might be so widespread that no single quantum enabled agent could dominate the PoW problem."
The real point of vulnerability is this: attacks on signatures wherein the private key is derived from the public key. That means that if someone has your public key, they can also calculate your private key, which is unthinkable using even today’s most powerful classical computers. So in the days of quantum computers, the public-private keypair will be the weak link. Quantum computers have the potential to perform specific kinds of calculations significantly faster than any normal computer. Besides that, quantum computers can run algorithms that take fewer steps to get to an outcome, taking advantage of quantum phenomena like quantum entanglement and quantum superposition. So quantum computers can run these certain algorithms that could be used to make calculations that can crack cryptography used today. https://en.wikipedia.org/wiki/Elliptic-curve_cryptography#Quantum_computing_attacks and https://eprint.iacr.org/2017/598.pdf
Most blockchains use Elliptic Curve Digital Signature Algorithm (ECDSA) cryptography. Using a quantum computer, Shor's algorithm can be used to break ECDSA. (See for reference: https://arxiv.org/abs/quant-ph/0301141 and pdf: https://arxiv.org/pdf/quant-ph/0301141.pdf ) Meaning: they can derive the private key from the public key. So if they got your public key (and a quantum computer), then they got your private key and they can create a transaction and empty your wallet.
RSA has the same vulnerability while RSA will need a stronger quantum computer to be broken than ECDSA.
At this point in time, it is already possible to run Shor’s algorithm on a quantum computer. However, the amount of qubits available right now makes its application limited. But it has been proven to work, we have exited the era of pure theory and entered the era of practical applications:
So far Shor's algorithm has the most potential, but new algorithms might appear which are more efficient. Algorithms are another area of development that makes progress and pushes quantum computer progress forward. A new algorithm called Variational Quantum Factoring is being developed and it looks quite promising. " The advantage of this new approach is that it is much less sensitive to error, does not require massive error correction, and consumes far fewer resources than would be needed with Shor’s algorithm. As such, it may be more amenable for use with the current NISQ (Noisy Intermediate Scale Quantum) computers that will be available in the near and medium term." https://quantumcomputingreport.com/news/zapata-develops-potential-alternative-to-shors-factoring-algorithm-for-nisq-quantum-computers/
It is however still in development, and only works for 18 binary bits at the time of this writing, but it shows new developments that could mean that, rather than a speedup in quantum computing development posing the most imminent threat to RSA and ECDSA, a speedup in the mathematical developments could be even more consequential. More info on VQF here: https://arxiv.org/abs/1808.08927
It all comes down to this: when your public key is visible, which is always necessary to make transactions, you are at some point in the future vulnerable for quantum attacks. (This also goes for BTC, which uses the hash of the public key as an address, but more on that in the following articles.) If you would have keypairs based on post quantum cryptography, you would not have to worry about that since in that case not even a quantum computer could derive your private key from your public key.
The conclusion is that future blockchains should be quantum resistant, using post-quantum cryptography. It’s very important to realize that post quantum cryptography is not just adding some extra characters to standard signature schemes. It’s the mathematical concept that makes it quantum resistant. to become quantm resistant, the algorithm needs to be changed. “The problem with currently popular algorithms is that their security relies on one of three hard mathematical problems: the integer factorization problem, the discrete logarithm problem or the elliptic-curve discrete logarithm problem. All of these problems can be easily solved on a sufficiently powerful quantum computer running Shor's algorithm. Even though current, publicly known, experimental quantum computers lack processing power to break any real cryptographic algorithm, many cryptographers are designing new algorithms to prepare for a time when quantum computing becomes a threat.” https://en.wikipedia.org/wiki/Post-quantum_cryptography
Expectations in the field of quantum computer development.
To give you an idea what the expectations of quantum computer development are in the field (Take note of the fact that the type and error rate of the qubits is not specified in the article. It is not said these will be enough to break ECDSA or RSA, neither is it said these will not be enough. What these articles do show, is that a huge speed up in development is expected.):
When will ECDSA be at risk? Estimates are only estimates, there are several to be found so it's hard to really tell.
The National Academy of Sciences (NAS) has made a very thourough report on the development of quantum computing. The report came out in the end of 2018. They brought together a group of scientists of over 70 people from different interconnecting fields in quantum computing who, as a group, have come up with a close to 200 pages report on the development, funding, implications and upcoming challenges for quantum computing development. But, even though this report is one of the most thourough up to date, it doesn't make an estimate on when the risk for ECDSA or RSA would occur. They acknowledge this is quite impossible due to the fact there are a lot of unknowns and due to the fact that they have to base any findings only on publicly available information, obviously excluding any non available advancements from commercial companies and national efforts. So if this group of specialized scientists can’t make an estimate, who can make that assessment? Is there any credible source to make an accurate prediction?
The conclusion at this point of time can only be that we do not know the answer to the big question "when".
Now if we don't have an answer to the question "when", then why act? The answer is simple. If we’re talking about security, most take certainty over uncertainty. To answer the question when the threat materializes, we need to guess. Whether you guess soon, or you guess not for the next three decades, both are guesses. Going for certain means you'd have to plan for the worst, hope for the best. No matter how sceptical you are, having some sort of a plan ready is a responsible thing to do. Obviously not if you're just running a blog about knitting. But for systems that carry a lot of important, private and valuable information, planning starts today. The NAS describes it quite well. What they lack in guessing, they make up in advice. They have a very clear advice:
"Even if a quantum computer that can decrypt current cryptographic ciphers is more than a decade off, the hazard of such a machine is high enough—and the time frame for transitioning to a new security protocol is sufficiently long and uncertain—that prioritization of the development, standardization, and deployment of post-quantum cryptography is critical for minimizing the chance of a potential security and privacy disaster."
Another organization that looks ahead is the National Security Agency (NSA) They have made a threat assessment in 2015. In August 2015, NSA announced that it is planning to transition "in the not too distant future" (statement of 2015) to a new cipher suite that is resistant to quantum attacks. "Unfortunately, the growth of elliptic curve use has bumped up against the fact of continued progress in the research on quantum computing, necessitating a re-evaluation of our cryptographic strategy." NSA advised: "For those partners and vendors that have not yet made the transition to Suite B algorithms, we recommend not making a significant expenditure to do so at this point but instead to prepare for the upcoming quantum resistant algorithm transition.” https://en.wikipedia.org/wiki/NSA_Suite_B_Cryptography#cite_note-nsa-suite-b-1
What these organizations both advice is to start taking action. They don't say "implement this type of quantum resistant cryptography now". They don't say when at all. As said before, the "when" question is one that is a hard one to specify. It depends on the system you have, the value of the data, the consequences of postponing a security upgrade. Like I said before: you just run a blog, or a bank or a cryptocurrency? It's an individual risk assesment that's different for every organization and system. Assesments do need to be made now though. What time frame should organisationds think about when changing cryptography? How long would it take to go from the current level of security to fully quantum resistant security? What changes does it require to handle bigger signatures and is it possible to use certain types of cryptography that require to keep state? Do your users need to act, or can al work be done behind the user interface? These are important questions that one should start asking. I will elaborate on these challenges in the next articles.
Besides the unsnswered question on "when", the question on what type of quantum resistant cryptography to use is unanswered too. This also depends on the type of system you use. The NSA and NAS both point to NIST as the authority on developments and standardization of quantum resistant cryptography. NIST is running a competition right now that should end up in one or more standards for quantum resistant cryptography. The NIST competition handles criteria that should filter out a type of quantum resistant cryptography that is feasable for a wide range of systems. This takes time though. There are some new algorithms submitted and assessing the new and the more well known ones must be done thouroughly. They intend to wrap things up around 2022 - 2024. From a blockchain perspective it is important to notice that a specific type of quantum resistant cryptography is excluded from the NIST competition: Stateful Hash-Based Signatures. (LMS and XMSS) This is not because these are no good. In fact they are excelent and XMSS is accepted to be provable quantum resistant. It's due to the fact that implementations will need to be able to securely deal with the requirement to keep state. And this is not a given for most systems.
At this moment NIST intends to approve both LMS and XMSS for a specific group of applications that can deal with the statefull properties. The only loose end at this point is an advice for which applications LMS and XMSS will be adviced and for what applications it is discouraged. These questions will be answered in the beginning of april this year: https://csrc.nist.gov/news/2019/stateful-hbs-request-for-public-comments This means that quite likely LMS and XMSS will be the first type of standardized quantum resistant cryptography ever. To give a small hint: keeping state, is pretty much a naturally added property of blockchain.
Quantum resistant blockchains
“Quantum resistant” is only used to describe networks and cryptography that are secure against any attack by a quantum computer of any size in the sense that there is no algorithm known that makes it possible for a quantum computer to break the applied cryptography and thus that system.
Also, to determine if a project is fully quantum resistant, you would need to take in account not only how a separate element that is implemented in that blockchain is quantum resistant, but also the way it is implemented. As with any type of security check, there should be no backdoors, in which case your blockchain would be just a cardboard box with bulletproof glass windows. Sounds obvious, but since this is kind of new territory, there are still some misconceptions. What is considered safe now, might not be safe in the age of quantum computers. I will address some of these in the following chapters, but first I will elaborate a bit about the special vulnerability of blockchain compared to centralized systems.
Why is it easier to change cryptography for centralized systems such as banks and websites than for blockchain?
Developers of a centralized system can decide from one day to the other that they make changes and update the system without the need for consensus from the nodes. They are in charge, and they can dictate the future of the system. But a decentralized blockchain will need to reach consensus amongst the nodes to update. Meaning that the majority of the nodes will need to upgrade and thus force the blockchain to only have the new signatures to be valid. We can’t have the old signature scheme to be valid besides the new quantum resistant signature scheme. Because that would mean that the blockchain would still allow the use of vulnerable, old public- and private keys and thus the old vulnerable signatures for transactions. So at least the majority of the nodes need to upgrade to make sure that blocks which are constructed using the old rules and thus the old vulnerable signature scheme, are rejected by the network. This will eventually result in a fully upgraded network which only accepts the new post quantum signature scheme in transactions. So, consensus is needed. The most well-known example of how that can be a slow process is Bitcoin’s need to scale. Even though everybody agrees on the need for a certain result, reaching consensus amongst the community on how to get to that result is a slow and political process. Going quantum resistant will be no different, and since it will cause lesser performance due to bigger signatures and it will need hardware upgrades quite likely it will be postponed rather than be done fast and smooth due to lack of consensus. And because there are several quantum resistant signature schemes to choose from, agreement an automatic given. The discussion will be which one to use, and how and when to implement it. The need for consensus is exclusively a problem decentralized systems like blockchain will face.
Another issue for decentralized systems that change their signature scheme, is that users of decentralized blockchains will have to manually transfe migrate their coins/ tokens to a quantum safe address and that way decouple their old private key and activate a new quantum resistant private key that is part of an upgraded quantum resistant network. Users of centralized networks, on the other hand, do not need to do much, since it would be taken care of by their centralized managed system. As you know, for example, if you forget your password of your online bank account, or some website, they can always send you a link, or secret question, or in the worst case they can send you mail by post to your house address and you would be back in business. With the decentralized systems, there is no centralized entity who has your data. It is you who has this data, and only you. So in the centralized system there is a central entity who has access to all the data including all the private accessing data, and therefore this entity can pull all the strings. It can all be done behind your user interface, and you probably wouldn’t notice a thing.
And a third issue will be the lost addresses. Since no one but you has access to your funds, your funds will become inaccessible once you lose your private key. From that point, an address is lost, and the funds on that address can never be moved. So after an upgrade, those funds will never be moved to a quantum resistant address, and thus will always be vulnerable to a quantum hack.
To summarize: banks and websites are centralized systems, they will face challenges, but decentralized systems like blockchain will face some extra challenges that won't apply for centralized systems.
All issues specific for blockchain and not for banks or websites or any other centralized system.
Conclusion
Bitcoin and all currently running traditional cryptocurrencies are not excluded from this problem. In fact, it will be central to ensuring their continued existence over the coming decades. All cryptocurrencies will need to change their signature schemes in the future. When is the big guess here. I want to leave that for another discussion. There are enough certain specifics we can discuss right now on the subject of quantum resistant blockchains and the challenges that existing blockchains will face when they need to transfer. This won’t be an easy transfer. There are some huge challenges to overcome and this will not be done overnight. I will get to this in the next few articles.

Working of Cryptocurrency Mining pool
Cryptocurrency is the most discussed and trending topic on various internet forums, communities, and social media. Many individuals are keen to enter the cryptoworld and unfold all the profits within it. Cryptocurrency can be bought from an exchange or mined through the mining pools. In this guide, we’ll understand the working of the cryptocurrency mining pool.
What is Mining Pool?
Cryptocurrency mining is the same as mining the metals from the earth. The individual or company that digs out the metal from the earth becomes the owner similarly the individual who discovers first the valid hash using the computational power becomes the owner and earns a block reward. The crypto mining can either be done solo using his/her own mining devices or through a mining pool.
As more and more enthusiasts participated in mining to earn a block reward became equally difficult and it would take centuries for a miner to generate a block because the probability of finding the hash value first and generating a block is directly proportional to the computing power in the network. The smaller the computational power the smaller is the chance of generating the next block. Hence a solution, to this problem mining pools were formed.
A mining pool is a group of miners pooling/combining their computational power together in order to mine a cryptocurrency quickly and earn a block reward consistently. Each contributing miner earns reward according to their investment in processing power. The working of mining pools depends on certain algorithms that are designed to check the authenticity and validity of the transactions. Miners are required to solve a complex math problem that requires millions of calculations with the help of High computational power. When the miners combined their computational power the block generation process happens at a much faster rate as compared to a single mining rig. For more understanding of mining please refer our previous blog (What is Bitcoin mining?)
Types of Mining Pools
  • Single mining pools: This type of mining pool mine only single cryptocurrency
  • Multi-currency pools: This type of mining pool mine different cryptocurrencies and gives the miner a chance to choose the cryptocurrency for mining timely depending rewards points offered.
  • Cloud mining pools: Cloud-based mining can be combined with mining pools by making an online contract. This type of mining pool allows individuals to participate in mining activity without even buying specialized equipment.
How rewards are shared on mining pools?
The rewards shared after successfully adding the new block to the blockchain vary from currency to currency. The reward sharings also depend on the factors like mining difficulty, the exchange rate between different coins, the hash rate and the block generation time. Some of the followed reward structures are as follows:
  1. Pay-per-share (PPS): This method offers instant payout depending on the miner’s contribution to finding the block. The payment is done using the pool's existing balance and can be withdrawn immediately.
  2. Shared Maximum Pay Per Share (SMPPS): It is the same as Pay-per-share (PPS) but limits the payout to the maximum that the pool has earned.
  3. Equalized Shared Maximum Pay Per Share (ESMPPS): This method is similar to (SMPPS) but the rewards are distributed equally among all miners in the pool.
  4. Proportional (PROP): The miner is rewarded the share that is proportional to the number of shares he has in the pool with respect to the pool’s total shares
Advantages of mining pools
  • Mining pools offer a more stable income
  • Mining pools lower costs of mining
  • Mining pools helps in generating a higher income
Disadvantages of Mining pools
  • There may be some interruptions in the Mining pools
  • There is a sharing of block rewards
  • There may be sometimes unfavorable pool reward structure
Widely-Used Mining Pools
  • Antpool: The largest pool available on the web offering mining of cryptocurrencies like BTC, BCH, LTC, ETH, ETC, ZEC, DASH, SCC, XMC, BTM
  • Minergate.com: A public mining pool mining of cryptocurrencies like ETH, ETC, ZEC, BTG, BCN, XMR, XMO, FCN, XDN, AEON
  • Btc.com: The most popular mining pool among miners offering cryptocurrencies BTC, BCH, ETH, ETC, LTC, UBTC, DCR to mine
  • BTCC: The largest Chinese pool in the world mining 7% of all existing blocks.
  • Slush: The most trusted mining pools on internet mining 7% of all available blocks.
Mining pools can definitely be a change to the entire mining process offering the highest and the real income without spending years depending on the computational powers. Hence, investing in a mining pool can be beneficial but always choose the mining pool that fits your personal needs and facilities.

So you’ve got your miner working, busy hashing away … but what is it really doing?

Posted for eternity @ https://vertcoin.easymine.online/articles/mining
Your miner is repeatedly hashing (see below for detail about a hash) a block of data, looking for a resulting output that is lower than a predetermined target. Each time this calculation is performed, one of the fields in the input data is changed, and this results in a different output. The output is not able to be determined until the work is completed – otherwise why would we bother doing the work in the first place?
Each hash takes a block header (see more below, but basically this is a 80-byte block of data). It runs this through the hashing function, and what comes out is a 32-byte output. For each, we usually represent that output in hexadecimal format, so it looks something like:
5da4bcb997a90bec188542365365d8b913af3f1eb7deaf55038cfcd04f0b11a0 
(that’s 64 hexadecimal characters – each character represents 4-bits. 64 x 4 bits = 256bit = 32 bytes)
The maximum value for our hash is:
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
And the lowest is:
0000000000000000000000000000000000000000000000000000000000000000 
The goal in Proof-of-Work systems is to look for a hash that is lower than a specific target, i.e. starts with a specific number of leading zeros. This target is what determines the difficulty.
As the output of the hash is indeterminate, we look to statistics and probability to estimate how much work (i.e. attempts at hashing) we need to complete to find a hash that is lower than a specific target. So, we can therefore assume that to find a hash that starts with a leading zero will take, on average, 16 hashes. To find one that will start with two leading zeros (00), we’re looking at 256 hashes. Four leading zeros (0000) will take 65,536 hashes. Eight leading zeros (00000000) takes 4,294,967,296 hashes. So on and so on, until we realize that it will take 2 ^ 256 (a number too big for me to show here) attempts at hitting our minimum hash value.
Remember – this number of hashes is just an estimate. Think of it like rolling a dice. A 16-sided dice. And then rolling it 64 times in a row. And hoping to strike a specific number of leading zeros. Sometimes it will take far less than the estimate, sometimes it will take far more. Over a long enough time period though (with our dice it may take many billions of years), the averages hold true.
Difficulty is a measure used in cryptocurrencies to simply show how much work is needed to find a specific block. A block of difficulty 1 must have a hash smaller than:
00000000FFFF0000000000000000000000000000000000000000000000000000 
A block of difficulty 1/256 (0.00390625) must have a hash lower than:
000000FFFF000000000000000000000000000000000000000000000000000000 
And a block of difficulty 256 must have a hash lower than:
0000000000FFFF00000000000000000000000000000000000000000000000000 
So the higher the difficulty, the lower the hash must be; therefore more work must be completed to find the block.
Take a recent Vertcoin block – block # 852545, difficulty 41878.60056944499. This required a hash lower than:
000000000001909c000000000000000000000000000000000000000000000000 
The achieve finding this, a single miner would need to have completed, on average 179,867,219,848,013 hashes (calculated by taking the number of hashes needed for a difficulty 1 block - 4,294,967,296 or 2 ^ 32 or 16 ^ 8 – and multiplied by the difficulty). Of course, our single miner may have found this sooner – or later – than predicted.
Cryptocurrencies alter the required difficulty on a regular basis (some like Vertcoin do it after every block, others like Bitcoin or Litecoin do it every 2016 blocks), to ensure the correct number of blocks are found per day. As the hash rate of miners increases, so does the difficulty to ensure this average time between blocks remains the same. Likewise, as hash rate decreases, the difficulty decreases.
With difficulties as high as the above example, solo-mining (mining by yourself, not in a pool) becomes a very difficult task. Assume our miner can produce 100 MH/s. Plugging in this into the numbers above, we can see it’s going to take him (on average) 1,798,673 seconds of hashing to find a hash lower than the target – that’s just short of 21 days. But, if his luck is down, it could easily take twice that long. Or, if he’s lucky, half that time.
So, assuming he hit’s the average, for his 21 days mining he has earned 25 VTC.
Lets take another look at the same miner, but this time he’s going to join a pool, where he is working with a stack of other miners looking for that elusive hash. Assume the pool he has joined does 50 GH/s – in that case he has 0.1 / 50 or 0.2% of the pool’s hash rate. So for any blocks the pool finds he should earn 0.2% of 25 VTC = 0.05 VTC. At 50 GH/s, the pool should expect to spend 3,597 seconds between finding blocks (2 ^ 32 * difficulty / hashrate). So about every hour, our miner can expect to earn 0.05 VTC. This works out to be about 1.2 VTC per day, and when we extrapolate over the estimated 21 days of solo mining above, we’re back to 25 VTC.
The beauty of pooled-mining over solo-mining is that the time between blocks, whilst they can vary, should be closer to the predicted / estimated times over a shorter time period. The same applies when comparing pools – pools with a smaller hash rate will experience a greater variance in time between blocks than a pool with a greater hash rate. But in the end, looking back over a longer period of time, earnings will be the same.
Hashes
A Hash is a cryptographic function that can take an arbitrary sized block of data and maps it to a fixed sized output. It is a one-way function – only knowing the input data can one calculate the output; the reverse action is impossible. Also, small changes to the input data usually result in significant changes to the output value.
For example, take the following string:
“the quick brown fox jumps over the lazy dog” 
If we perform a SHA256 hash of this, it results in:
05c6e08f1d9fdafa03147fcb8f82f124c76d2f70e3d989dc8aadb5e7d7450bec 
If we change a single character in the input string (in this case we will replace the ‘o’ in ‘over’ to a zero), the resulting hash becomes:
de492f861d6bb8438f65b2beb2e98ae96a8519f19c24042b171d02ff4dfecc82 
Blocks
A block is made up of a header, and at least one transaction. The first transaction in the block is called the Coinbase transaction – it is the transactions that creates new coins, and it specifies the addresses that those coins go to. The Coinbase transaction is always the first transaction in a block, and there can only be one. All other transactions included in a block are transactions that send coins from one wallet address to another.
The block header is an 80-byte block of data that is made up of the following information in this order:
  • Version – a 32-bit/4-byte integer
  • Previous Block’s SHA256d Hash – 32 bytes
  • Merkle Hash of the Transactions – 32 bytes
  • Timestamp - a 32-bit/4-byte integer the represents the time of the block in seconds past 1st January 1970 00:00 UTC
  • nBits - a 32-bit/4-byte integer that represents the maximum value of the hash of the block
  • Nonce - a 32-bit/4-byte integer
The Version of a block remains relatively static through a coin’s lifetime – most blocks will have the same version. Typically only used to introduce new features or enforce new rules – for instance Segwit adoption is enforced by encoding information into the Version field.
The Previous Blocks’ Hash is simple a doubled SHA256 hash of the last valid blocks header.
The Merkle Hash is a hash generated by chaining all of the transactions together in a hash tree – thus ensuring that once a transaction is included in a block, it cannot be changed. It becomes a permanent record in the blockchain.
Timestamp loosely represents the time the block was generated – it does not have to be exact, anywhere within an hour each way of the real time will be accepted.
nBits – this is the maximum hash that this block must have in order to be considered valid. Bitcoin encodes the maximum hash into a 4-byte value as this is more efficient and provides sufficient accuracy.
Nonce – a simple 4-byte integer value that is incremented by a miner in order to find a resulting hash that is lower than that specified by nBits.

Has the Bitcoin Hash Rate Peaked? Comparisons with Oil Show Interesting Findings

Has the Bitcoin Hash Rate Peaked? Comparisons with Oil Show Interesting Findings

https://cryptoiq.co/the-bitcoin-mining-hash-rate-has-similarities-to-peak-oil/
The Bitcoin mining hash rate had been exponentially increasing on average since the genesis block in 2009, from MH/s, to GH/s, to TH/s, to PH/s, to EH/s, and it reached an all-time record high of 62 EH/s on 26 August 2018. Since this peak was reached, the Bitcoin mining hash rate gradually plateaued and has now decreased. The chart of Bitcoin mining hash rate actually looks quite similar to a peak oil chart except on a much faster time-scale, as can be seen in the comparison between Bitcoin’s hash rate over the course of 2 years from Blockchain.com and North Sea oil production from an article in The Oil Drum: Europe by Euan Mearns. As explained below, the dynamics between peak oil and peak Bitcoin mining are similar, with the key difference that Bitcoin mining is decentralized and oil is not.

Geologist M. King Hubbert is the founder of the peak oil theory, which states that there is a point when the maximum extraction rate of petroleum is reached, after which a terminal decline in production ensues. The peak rate of extraction of Bitcoin of course occurred during the period after the genesis block and before the first block halving, when the block reward was at its maximum of 50 Bitcoins. However, this is not the peak rate of mining profitability, since Bitcoin increased in price by orders of magnitude through the year 2017. The peak rate of Bitcoin mining profits undoubtedly was simultaneous with Bitcoin’s all-time record high of USD 20,000 in December 2017.
The reason the peak hash rate did not coincide with the peak rate of Bitcoin mining profits is because the rally happened so quickly that mining operations were not able to add rigs fast enough, so there was a lag effect. Even for mining operations with large amounts of capital it can take months to obtain the amount of mining equipment that they want, and for other mining operations it took even longer because they had to obtain investors, buy land, build infrastructure, and only then could they install the rigs and begin hashing.
The Bitcoin mining hash rate chart implicitly indicates that 30 EH/s of Bitcoin mining equipment has been taken offline due to lack of profitability, which represents tens of billions of USD of wasted rigs. This suggests that Bitcoin miners were caught by surprise by the decline in Bitcoin’s price from USD 20,000 to less than USD 4,000 as of 4 December 2018.
Coming back to the peak oil comparison, the current Bitcoin mining scene is like a rapid version of peak oil, combined with lack of coordination. Oil mining is a centralized and coordinated activity, where the oil is prospected, land is leased out and then an appropriate number of wells are drilled. With oil mining, companies cannot drill as many wells as they want, or drill wells on someone else’s lease, since this is all closely controlled by contractual agreements. Bitcoin mining is decentralized, and no one has a lease or contract to only mine with a certain amount of hash rate. Anyone in the world can run as much Bitcoin mining rigs as they can afford. The effect is that people all around the world are sticking their straws into the Bitcoin mining network all at the same time, and they sucked it dry. Essentially, so many people started up new mining operations at once without coordination, that the Bitcoin mining hash rate went way past its equilibrium, which hurt everyone involved. This is akin to if oil drilling was a decentralized process, and anyone who wanted to drill for oil could drill in the same field. The oil field would be sucked dry really quick, and then most of the drills would be shut down due to lack of profits.
There is hope for Bitcoin miners however. The price of Bitcoin simply has to rally, and all of the disenfranchised miners could restart their rigs, and then it would be back to the races and new rigs could begin being added. However, due to the decentralization of Bitcoin mining, the network hash rate will likely periodically rise past its equilibrium point, leading to catastrophic conditions for miners like we are experiencing today at points in the future. The only thing that could prevent the scenario we are experiencing today is a Bitcoin rally that lasts forever, which is obviously not possible.
James McAvity tweeted that Bitcoin mining is still profitable in the current environment, and does some simple linear calculations to prove this point. He also argues that miners are forced to keep mining due to business agreements, choose to HODL in expectation of a rally, and continue mining in expectation of a downward difficulty adjustment as other miners go offline.

Some of what McAvity says is true, but the reality is that Bitcoin mining is a highly non-linear system, and calculating the support level for mining is somewhat pointless, since it is different for every miner. Bitcoin mining profitability depends on Bitcoin’s price, the Bitcoin network hash rate which is directly correlated to mining difficulty, and the technological efficiency of Bitcoin mining rigs. These 3 factors are related in a non-linear and ever-changing way.
Instead of trudging away at trying to develop a set of equations that determine mining hash rate behavior, one could simply look at the Bitcoin mining hash rate chart at the beginning of this article to understand what is going on. Bitcoin mining profitability is different for each individual miner, and the hash rate has trended downwards as individual miners have made the decision to shut down rigs. Clearly there was a fundamental mining profitability support level in the USD 6,000-7,000 range, since that is where Bitcoin’s price was when mining peaked and plateaued. There are clearly numerous miners who became unprofitable on the descent from that level to less than USD 4,000 today, and now approximately 50% of the Bitcoin mining equipment that exists cannot profitably mine. The decrease in Bitcoin’s mining difficulty of 15% on 3 December 2018 could help bring some of those miners back online, at least if the price stays at current levels around USD 4,000, but this will not change the overall trend.
When it comes down to it, Bitcoin’s price is in control of Bitcoin mining profitability, and if the price goes up we could see a reversal of the hash rate downtrend and eventually a 2nd peak in Bitcoin’s network hash rate. However, if price continues to go down, the Bitcoin mining hash rate chart will follow a similar pattern to peak oil charts. The reality will likely be a combination of both. Bitcoin bear markets tend to last years, and get more severe, but eventually the rally comes and then Bitcoin exceeds its all-time record high. This would lead to a steady decrease in Bitcoin’s mining hash rate like the peak oil chart, followed by a rapid re-engagement of old mining rigs that have been taken offline, and then the addition of new generation Bitcoin mining rigs once the equilibrium hash rate exceeds 60 EH/s.

AMA Recap: DBCrypto and 8BTC
by bloXroute Team (Original post here)
https://preview.redd.it/wofpz6u4s4m21.png?width=1200&format=png&auto=webp&s=130a488552c9485affdc14a08f8f8a49c6b48cb8
This past month the bloXroute team participated in 2 AMA’s. Our Co-Founder Professor Emin Gün Sirer synced up with our Chinese-speaking community on the 8BTC Forum, and our Co-Founder and Chief Architect Professor Aleksandar Kuzmanovic, Strategy & Operations Manager Eleni Steinman, and Marketing Associate Brooke Walter connected with blockchain enthusiasts on the DBCrypto Telegram group.
There were many great questions asked so we wanted to share our answers with the rest of our community on Medium. For some of the questions, we expanded upon our answers and edited for clarity and brevity.
The questions are organized into four sections: Tech, BLXR, General, and the Blockchain Ecosystem.

Tech

Can someone explain the “magic gateways” a little more? Is this patented and closed source tech?
  • “Magic gateway” is a small piece of code that sits on a machine running a blockchain node with one side speaking the blockchain “language” with the node, and on the other side speaking bloXroute “language” with our Relays. It also shrinks blocks from the nodes to the Relays, propagates transactions etc. Yes this has been patented for a simple reason — the work was initially done at a University, hence we had to license (our own work) from the University. That’s how it works. While we patented the system, we are going to open source the Gateways.
When will the source code be released?
  • The source code for the Gateway software will become available from Day 1, i.e., as soon as we start testing with miners. The source code for the rest of the system, i.e., Relays, will become available soon after.
From reading the whitepaper it seems as though on-boarding bloXroute can take a bottom up approach. I.e. it sounds like crypto miners can start using the bloXroute network right away, without needing to integrate software into the bloXroute servers or get any approval from the developers of the crypto project? Is this right?
  • That’s right! Any miner can start using bloXroute on its own without any approval. We will provide open source code that miners download, we call magic gateways, that is run on the same machine they mine on. Miners send blocks to the gateway like they would any other peer node. And that’s it. Since bloXroute BN lets you hear about and send blocks faster, miners who use it are obviously at an advantage.
Will the blockchain be able to test bloXroute’s net neutrality? If yes, how? Will bloXroute’s net neutrality testing ability be on the developer or miner level?
  • Certainly! Net neutrality is at the heart of bloXroute, and something I am personally passionate about. Net neutrality mechanisms (please see the WP for details) will be enabled from day one. Everyone, including miners and developers, will be able to test, in real time, bloXroute’s network and its behavior.
How can bloXroute be decentralized and trustless? Does it rely on servers? If we can’t find a better way to solve block propagation problems other than bloXroute, then obviously nodes (especially mining nodes)have to completely rely on bloXroute. If bloXroute has any problems, the whole network will be at risk.
  • Excellent question that gets to the heart of bloXroute’s core contribution. bloXroute is a unique solution that is *centralized yet trustless*. It consists of a network of servers operated very efficiently by a centralized entity — this is how it achieves its high performance. At the same time, the technology is constructed such that these servers *cannot* misbehave. They cannot discriminate on the basis of transaction content, and they cannot selectively censor. So, the overall network is efficient because it’s centralized, like Akamai’s content distribution network, and it’s also trustless, like Bitcoin’s underlying network. Also, by open-sourcing our entire codebase (once the system reaches some maturity) we enable everyone to run a backup network to take over in case bloXroute is shut down by any means, preventing it from becoming a single-point-of-failure.
Also, I remember that ‘bloXroute will keep neutrality by encrypting blocks’, but what if somebody uses bloXroute to send spam? Will it be a problem?
  • Indeed, we have implemented various measures to handle the spam issue. In particular, the bloXroute network keeps and propagates provenance information, allowing the system to limit the traffic a node sends based on their usage of the system. Keep in mind that all large networks, whether it’s Google’s, Facebook’s or Akamai’s, are under constant spam attacks. We use well-established techniques from that domain to ensure that spammers can be efficiently identified and limited.
What is a sufficient number of servers?
  • Our V1 is going to have around 15 servers on 5 continents, roughly. Blockchain traffic currently isn’t particularly large. We hope to change that!
Is it advantageous for miners to be in relative close proximity to a BloXroute server?
  • Yes. But the difference is very small. A really dramatic difference will be between bloXroute-enabled vs. non-bloXroute enabled miners.
Could you elaborate on the servers a bit more? I heard Uri talking about utilizing trusted organisations to do this. I know my concern is that this may create some level of centralised power.
  • We are fully aware of this concern. This is why we are making sure to utilize a large number of independent providers. This is creating a lot of operational issues on our end (because different providers use different software environments) but this is a top priority for us.
How quickly will idle backup networks be operational/online in the case of a main bloxroute network fatal failure? Does this backup network set-up require some work/adjustments on the client/nodes side?
  • The backup will be automatic, such that the effects of a possible failure on the mainnet is minimized. Given that the process will be automatic, no adjustments will be needed on the client side.
Have you established an “ideal” number of independent providers to reduce such concerns? Or is this something still being established?
  • There’s no magic number, the more the better!
I assume having servers in different geographical regions is important. The EU for example could outlaw BloXroute servers. I assume it would be way too expensive for a regular person to setup a BloXroute server?
  • I am hopeful the EU would not do that! :) But the point is that even in absence of servers in a particular region, things can still work pretty well for users in that region.
If that was the case, will they be disadvantaged as the message will need to be relayed further?
  • Necessarily so. But the system would still be operational, and would be able to operate at a fairly high TPS rate.
From both a tech and adoption level, what are some of the biggest difficulties bloXroute faces?
  • Technical difficulties are present on a daily basis, but we are coping with them. As a technical person, I simply know we will resolve them all. I am also convinced that a number of blockchain communities will adopt our system. But if you ask what a bigger challenge is, I think adoption.

BLXR

Does bloXroute have native tokens? If yes, when will the tokens be released? Is it an ERC20 token? Will it be listed on exchanges? What can the tokens do on your network?
  • Yes, bloXroute will have BLXR tokens, which will be listed on exchanges. The BLXR tokens are security tokens that entitle the holder to a share of the revenues of the company. Of every future dollar that bloXroute makes, a proportion goes into a pot, and this pot is divided among the BLXR holders. Think of it as instant, auditable dividends in perpetuity. And BLXR tokens thus act like a fund, where the fund’s contents change over time to track whichever coins are using bloXroute more. If BCH miners use bloXroute, BLXR will have more BCH in it; if ETH adopts bloXroute, then it’ll swing towards ETH, etc. So the tokens can serve as a blanket bet on adoption and use of cryptocurrencies, kind of like how Akamai was a play on Internet content being in demand. I will leave it up to the company to announce its projected dates. I’m focusing mainly on the technology behind the scenes.
Is it correct that you plan to go down the STO path or simply the security token path and the BLXR will be a security token?
  • Yes, BLXR is a security token. The good thing is that we’re clear about this from the very beginning. Hence we were able to cope with regulations on time.
When do you plan to do the STO?
  • Our team of lawyers is working very closely with the SEC to take all of the required steps to ensure everything we do is in compliance with regulations. We hope to have all necessary approvals for an STO in Q3 / Q4 2019.
That’s really great that you’ve been working with the SEC. Does that mean you plan to sell the BLXR token to American citizens?
  • We hope that to do as wide of a sale as possible, so not just Americans.
How does this work? What jurisdiction have you chosen to setup this token etc? Or is this all still being figured out?
  • It has to do with the regulation you file under. Some regulations require that you only raise from accredited investors and others let you raise from anyone.
Will accredited investors only be able to participate in the the BLXR token sale or is there a plan to try an include non-accredited investors as well?
  • The plan is to make it as wide of a sale as regulation allows. We (our lawyers) are working hard so it’s not just accredited investors.
You have recently changed your BLXR security token from 50% revenue reserve model to 100% revenue direct dividend model. How direct will it be? In what time frame or frequency will BLXR token holders will receive their pro rata share of collected revenues to their wallets?
  • 100% of the fees associated with the cryptocurrencies using bloXroute’s BDN become immediately available for withdrawal by BLXR token holders. Right now the plan is for a calculation to run once every 24-hours to update what we call an “Owner balance” — this is how much crypto is available for withdrawal for a given BLXR holder based on their pro-rata share. To withdraw one’s dividends, a BLXR holder must provide a wallet address in the same currency as the crypto they wish to withdraw. The owner balance will then instantly update to reflect this outflow.
How will bloXroute operations be covered in this new direct dividend model?
  • In the new model 100% of the revenues will go to token holders. bloXroute, as a token holder, can use the revenues it receives for its ownership portion to fund operations.
With BLXR being an ERC-20 token, does Bloxroute plan to set up the benefits of the token (accumulation of relative % of fees for projects using the network) so that it can be accumulated by the owner whilst also possibly locking BLXR in a MarkerDao CDP?
  • Dividends will accumulate in a reserve account and be available for withdraw. Our current plan is for Owner Balances to be updated every 24 hours. BLXR holders can transfer their dividends to their wallets and use them as they wish. :)

General

I understand that one of the benefits of bloxroute for the ecosystem is users will have a much lower fee to pay for their transactions. Will users be able to get this much-lower-fee benefit from bloxroute only through wallet(s) they use by choosing to pay a *tiny* fee to bloxroute instead of a *large* fee to miners or can they also get that benefit in some other way?
  • To start, users can use bloXroute immediately as the first 100 TPS are always free. Only after 100 TPS can a user choose to pay bloXroute a tiny fee to reduce her overall fee (albeit a user would only choose to pay bloXroute if this is true). All users benefit from bloXroute on day one as the first 100 TPS are always free. Users do not have to use wallets that partner with bloXroute to take advantage of the fee reduction service, but it’ll certainly be the most streamlined method. Any user that knows bloXroute’s public address can include in their transaction an additional output that pays bloXroute’s public address to reduce her overall fee.
Typically, how many X tps improvement should we see for the various major blockchains that bloXroute will target?
  • We are targeting approximately 3,000 TPS for Bitcoin and Ethereum.
In terms of technology, what is bloXroute’s core competitiveness? How many people are on your team?
  • Our core competencies are as follows: (1) we have some of the world’s foremost experts on blockchain and network scaling, (2) we have innovated across all aspects of the emerging blockchain stack in the past and bring that experience to bear on the chain scaling problem, and (3) we are the first group to identify Layer-0 as a scalability bottleneck, the first to apply network neutrality techniques to blockchains, and thus the group with the most extensive track record on how to build efficient and trustless systems. The team is just over 20 employees, it is hard to keep track now because, in addition to our headquarters in Chicago, we also have a satellite office in Tel Aviv, Israel and two need employees start this week. We are currently building our platform. Though the core of the platform has been in operation for 2.5 years already on the BTC and BCH networks, we are extending it to other systems, e.g. ETH, and adding new features.
How does bloXroute’s solution work on different blockchain networks?
  • bloXroute’s solution has been operating continuously for the last 2.5 years. In that time frame, it has been deployed on Bitcoin (BTC) and Bitcoin Cash (BCH). It has ferried every transaction and every block found in that time frame. To this, we recently added the ability to support Ethereum. And we recently announced a partnership with a large miner. In all of these cases, bloXroute provides an additional fast-path to existing coins for the delivery of financial data, just like Akamai added a fast path for the delivery of regular content on the Internet. It’s optional, opt-in, and completely voluntary. It’s just a faster way to deliver blocks and transactions. In return for ferrying this financial data, bloXroute collects transaction fees, and BLXR tokens receive these collected feeds.
With bloXroute already forming a partnerships with mining companies, do you plan to establish more relationships with similar organisations? If so, given the obvious concerns about the environmental impact of traditional mining, does bloXroute aim to establish/support relationships with mining companies who utilise renewable and sustainable energy?
  • We hope to establish relationships with all miners :) In regards to environmental concerns, our BDN actually helps miners more efficiently utilize their power consumption. Since miners hear about blocks sooner, they can immediately start mining the next block, and thus more efficiently utilizing their resources.
When will you start v1 testing with miners?
  • Early to mid March.
Will the v1 testing be predefined (for preselected miners/mining pools) or it will be possible to join the testing on the go? How can a miner apply for the testing?
  • Yes, the V1 testing will happen with a predefined group of miners. If you’d like to join, please send me an email ([[email protected]](mailto:[email protected])) and I’ll follow up.
Will the v1 testing be with one or with multiple blockchains? Will there be BTC and/or ETH miners in the v1 test pool?
  • It will be with multiple blockchains and yes, we connect with both BTC and ETH (and BCH) miners in V1.
Will bloXroute produce better results (TPS) for PoW or for PoS consensus protocols?
  • We are currently working with PoW and we are seeing some great results (still can’t share publicly). We should definitely see a comparable performance with PoS, but we currently have no empirical data.
Are there any difficulties you faced trying to convince major blockchains like btc, eth etc to increase block size?
  • We view ourselves as providers of networking that removes the scalability bottleneck. It is up to each community to take advantage of that efficiency how they see fit. That said, we already know some communities want scale. For example BCH has 32 MB blocks because after 32MB the thing breaks (i.e. they hit the scalability bottleneck). With bloXroute, I’d expect them to increase their blocksize.
Which pipelines of blockchains likely to come on board 1st on bloXroute in 2019?
  • In V1 we will provide support for BTC, ETH, and BCH. We are talking to many other blockchain communities, and will provide an open API allowing any blockchain to use bloXroute.
If 10% of the blockchain miners/pool have 10% of the hash power (which results in approximately a 10% probability of mining a block) and they start using bloxroute while the other 90% of miners/hash power do not use bloxroute yet (gradual deployment), how does the usage of bloxroute benefit the 10% of miners vs. the other 90%?
  • Good question. The benefits for early-adopting miners start to kick in immediately. In your example, the probability of the 10% of miners that use bloXroute increases above 10% the probability to win a mining round. This is because they “waste” (much) less time on mining blocks that will not eventually get “on chain”.
Does the TPS order of improvement through bloxroute depend on the network size and distribution of nodes (decentralization level) of particular blockchain?
  • It necessarily does. The larger and more decentralized a network is, the TPS rate decreases. The big difference is that without bloXroute, the TPS decreases exponentially, i.e., very quickly. With bloXroute, we are seeing sublinear, i.e., marginal, degradation in TPS as the network size increases.
Are you partnering already with some wallets? If yes, with which ones? If not, is it too early to disclose?
  • Our first goal is to gain adoption. Once we have adoption, we plan on working with wallets to add in an option to streamline the process of including a bloXroute fee. We expect wallets to include such a fee to have an advantage because it offers their users lower overall fees compared to competitors. It would be up to the wallet to decide to show an “bloXroute transaction” feature or simply show lower fees. That said, we are very well connected to some of the most successful wallets in the crypto ecosystem, and have already discussed the matter with some of them.
Do you foresee users migrating to wallets that partner with bloXroute from the ones that don’t?
  • Users do not have to use wallets that partner with bloXroute to take advantage of the fee reduction service, but it’ll certainly be the most streamlined method. Any user that knows bloXroute’s public address can include in their transaction an additional output that pays bloXroute’s public address to reduce her overall fee. Our first goal is to gain adoption. Once we have adoption, we plan on working with wallets to add in an option to streamline the process of including a bloXroute fee. We expect wallets to include such a fee to have an advantage because it offers their users lower overall fees compared to competitors. It would be up to the wallet to decide to show an “bloXroute transaction” feature or simply show lower fees.
Will it be easy for a wallet to integrate bloXroute or it will require deeper dive?
  • Integration with wallets should be equally straightforward, from the technical point of view. We plan to actively work with open-sourced wallets to help them implement the change. The change includes a UI update to prompt the user and ask if they want to use bloXroute or not, and if they do, update the transaction to commit a tiny fee to a publicly-known bloXroute address.
Are you on track with your roadmap?
  • We are only a few weeks behind on our roadmap (we wanted to do our miner test for end of Feb and now it is early march) but I think for the tech world that’s still pretty good!
Did crypto winter changed your roadmap in certain aspects?
  • The crypto winter I think actually helped us. We are a free service to make miners more money. That has to be appealing in this environment.
When will the Proof of Concept be released?
  • The PoC should come at a similar time like V1, maybe a couple of weeks later, we’ll see.
What is the biggest challenge you’ve encountered after starting the company? What has helped you overcome challenges and stick to your goals?
  • Biggest challenge we have faced is finding talented individuals who understand this technology. The area is brand new, and it’s difficult to find qualified engineers, builders, and business folks. What makes me really motivated every morning is looking at the world and noticing just how antiquated our current systems are, how much they operate based on trust, and how much better they would be if they were open to all and auditable by anyone.
The white paper doesn’t give a full description of bloXroute’s tech, instead it gives a very simple explanation. Do you have concrete plans on how your project will be applied?
  • Our technology has been in operation for 2.5 years. Writing a whitepaper is a difficult task, trying to make a complex technology accessible to the masses. That said, I am pretty sure that we covered the core of our plans, and we have more papers in the pipeline describing the operation of the system for an academic audience. [Check out our resources page for detailed explanations about our technology]

Blockchain Ecosystem

People are talking a lot about Layer-2 scaling solutions in recent years. Compared with layer-0, will layer-2 be a better scaling choice? Or does it depend on different scenarios?
  • When it comes to scaling, there is no “one good layer to scale.” To reach really large numbers of transactions per second, one needs to tackle the bottlenecks at all levels. And Layer-2 cannot actually be made secure unless Layer-1 has enough space to on-board new users, as well as settle the transactions from existing channels. This all cannot be done at 3 tps. To support 1,000,000 tps and above, the underlying chain has to offer high throughput. So it’s absolutely essential to examine Layer-0 solutions.
You said currently there’s no crypto that can be truly decentralized. You also believe PoS is better than PoW. Does that mean that you think bitcoin is not decentralized? What’s the problem with bitcoin’s PoW mechanism?
  • Bitcoin’s blockchain today is created by around 19 mining entities. Some of these are pools, but nevertheless, these are individuals that came together and are operating in unison towards a common aim — they may not have corporate paperwork filed, but they are indistinguishable from any other corporate entity at this point. Just 4 of these command the majority of the hashpower. That’s it, the sum total of Bitcoin’s decentralization. EOS has 21 block producers. Ethereum has 11 miners now, and will reach around 60 with Casper. These are all tiny numbers. The big elephant in the room that no one dares to talk about is precisely how centralized most coins are today.
Do you find there is enough awareness about the block propagation as one of the major (if not the major) scalability bottlenecks within the crypto community/blockchains?
  • The short answer is no. Many people have heard about scalability being a hot topic in crypto/blockchain, but almost no one knows exactly what or where the bottleneck is. That’s why one of the most important parts of telling our story is educating at the same time. The blockchain community has many different types of people with varying levels of knowledge, so it’s a balance to develop a voice that speaks to everyone. In response to this challenge we have developed an educational Youtube series where we give detailed explanations about topics in crypto and blockchain. We hope it will provide tools to have more technical understanding and meaningful conversations about our product and the ecosystem in general.
During the BCH Hash War there was a block propagation bottleneck real case scenario on the mainnet when BSV tried to mine large blocks — something like 40MB and later 64 MB, but at both trials they failed on block propagation as it took too long and forks occurred. The large blocks were orphaned so the experiment clearly failed. As bloXroute’s focus is on this exact scalability bottleneck, block propagation, you came out as a *winner* from the hash war according to Professor Sirer. Have you experienced some benefits of being a winner, such as a larger awareness and interest in your project within the crypto and blockchain community?
  • We are having a lot of communication and open discussion with a lot of blockchain projects out there. We did indeed notice an increased interest after the events that you mention above.
What if industrial giants launched their own public chains one after another, what do you think the community should do?
  • This is exactly what we are going to see, with Facebook leading the way. I’m not too worried about these corporate approaches. While these companies have immense resources, they are starting quite late and do not have the kinds of thought leadership we possess on building peer-to-peer systems. All of these big behemoths are experts at building centralized client-server systems, which are the exact antithesis of what we are building with cryptocurrencies. So I don’t think we should be worried or do much: let them build out, welcome their efforts, and treat them the same way we treat every other altcoin. They will play a big role in onboarding new users into crypto, and they will help make the space more healthy and exciting for all of us.
What different scaling challenges are Ethereum and Bitcoin facing now? What do you think of these challenges?
  • The scaling problems faced by these two systems are slightly different. Bitcoin is a payments system. As such, it is concerned primarily with point-to-point value transfers. And it is facing a basic capacity problem: if everyone in Venezuela were to switch to Bitcoin today, every adult would get to transact only once per month! That’s clearly nowhere near the dream that has been sold to the masses. And it’s not clear what Layer-2 can achieve, because its capacity depends on the emergent network. At the moment, most attempts to send $1000 over LN fail. The challenge in Bitcoin and similar systems is to retain the security of the underlying protocol, avoid forks, and at the same time, increase the number of transactions per second. Naive attempts to do this, for instance, by arbitrarily increasing the block size to really large numbers, are not a good idea. We have seen that BSV is going down this route, and it is leading to excess centralization. bloXroute can help avoid centralization, and help drive protocol scales up by orders of magnitude. The challenges faced by Ethereum are slightly different. The interactions with smart-contracts tend to be multi-point to multi-point, that is, they involve multiple parties. So we see a different, more difficult problem emerge. And Ethereum is driving its network to its limits at the moment. The Ethereum mining network is beginning to show signs of centralization. ETH’s current set of block size and block frequency parameters are a little bit aggressive, and we are seeing signs that would indicate an advantage for mining centralization. bloXroute can help reverse this process and enable the protocol to be driven even more aggressively.
Ethereum researchers claim that their sidechain snark handles 17,000 TPS, do you think we can achieve higher capacity while the network is absolutely safe?
  • We can, and need to, achieve far higher numbers if the blockchain revolution is going to be anywhere near as big as it can be. If IoT devices go online, we will need 1M tps. On the other hand, I’m highly skeptical of all performance claims. BTC achieves around 4tps today, while ETH achieves 15 on a good day. Achieving 100–500, sustained in the real world, is actually very difficult. Any time I hear a number in excess of 10,000 tps, and the technology involved still uses LevelDB, I know that the numbers are obtained in laboratory conditions. That said, I believe this announcement was referring to a sidechain with a small number of trusted peers. In such a setting, sure, one can do anything because the trustlessness is not an issue. I’m concerned about public blockchains, where the nodes do not and cannot trust each other. We can only get to 10,000tps and above by re-thinking Layer-1, as we are doing with Avalanche, and re-doing Layer-0, as we are doing with bloXroute.
