Whether you’re a crypto faithful or just a passer-by who happened to notice a bitcoin headline, you’ve likely come across the halving.
The roughly quadrennial event is arguably an important one in the progression of the bitcoin network. For all the adjustments and changes to bitcoin’s code since its launch – and the evolution of the ecosystem and industry around it – the issuance cycle and bitcoin’s predetermined supply have never been altered.
The halving is, perhaps, emblematic of both bitcoin’s philosophical basis as well as its technical progression. It’s also a heck of a lot of fun, with past halvings inspiring celebrations and watch-parties for those counting down each block until the halving officially kicks in.
So, let’s get into it.
What is the bitcoin halving?First, some basics. Each bitcoin block brings three things with it: transactions, newly-created bitcoins and fees.
For example, block number 625875 included 1,478 transactions worth 4899.23684782 BTC. The block was created by BTC.com. In exchange for making that block, BTC.com earned 12.5 BTC and 0.08439752 BTC in fees.
When bitcoin first launched, each block had a subsidy of 50 BTC. In 2012, that amount fell to 25 BTC per block, and in 2016 it was further reduced to 12.5 BTC per block. With upcoming halving – currently estimated to take place in or around May 12, when the network hits its 630,000th block – that amount will drop to 6.25 BTC per block.
To date, roughly 18.3 million bitcoins have been minted out of a total of 21 million that will ever be created.
Wait, what’s a miner?Miners create the blocks of transactions that make sending BTC throughout the distributed bitcoin network possible. They append new blocks to the ever-growing chain – that’s the blockchain – and are rewarded with new bitcoins for doing so.
To create block 625875, BTC.com ran its miners and sought to be the first to create the next block. Mining is resource-intensive by design, and while some have described the process as an effort to solve a complex mathematical problem, a more apt description might be that miners rapidly try forming different numbers until they land on the right one.
Mining is a key element of Bitcoin’s security. As more blocks are added, it becomes more difficult to rewind the transactional clock and undo transactions from earlier blocks.
The generation of new BTC is how miners make money; their profits come from the sale price minus the cost of electricity, labor and everything else it takes to keep their legions of mining machines humming. The block reward is also the bedrock incentive for miners to keep the block production process – and, as a result, the transaction history – honest. By getting paid in bitcoin, they have an interest in seeing its price stay steady. A transaction history prone to manipulation or tampering would have no value.
The cycle of block reward or subsidy halvings is baked into bitcoin’s code. The reward reduction underpins bitcoin’s controlled supply, serving as a kind of digital parallel to finite natural resources.
So miners create new bitcoins, and with the halving, they’ll create fewer new bitcoins.
Yes. As The Block highlighted on Monday, miners currently make an estimated $13.4 million per day in new bitcoin and fees. Once the halving kicks in, that’ll drop to about $6.7 million total in the even that prices remain steady.
Of course, that number may very well fluctuate depending on the market reaction in the hours, days, weeks and months ahead. For a deeper look, check out The Block’s Larry Cermak by-the-charts column on the halving published on Monday.
I heard that the price is going to go up with the halving. Is that true?
Much digital ink has been spilled in recent months on the question of whether bitcoin’s price will rise as a result of the halving.
There are varying theories as to why: the halving will bring new market entrants, the tightening of issuance will spur more buying, or history will basically repeat itself. For example, bitcoin’s price rose above $1,000 a year after its 2012 halving. The July 2016 halving saw bitcoin’s price around $660 – a year later, the price had soared above $2,000.
But those were, arguably, different times, and next month’s halving is the first to occur after the parabolic craziness of early 2018.
A price increase isn’t a foregone conclusion – though, to be sure, neither is a drop or a continuation of the status quo.
Okay…so the number isn’t going up?
Nobody knows. And this isn’t investment advice, so quit asking me.
Who will be affected by this?One can expect that major portions of the bitcoin-facing industry could be impacted in one way or another.
As noted above, miners will see the primary element of their income – new bitcoins – be cut in half. That’s bad news for miners who are operating older, less efficient hardware or borrowed significant sums of money to get new equipment – especially those hit by the recent turbulence in crypto markets. Bitcoin’s hash rate – a measure of the network’s computational power – could slip as some operations find themselves unable to make a profit and thus are forced to power down.
Exchanges will be affected because they’ll be front-and-center for any market response. It could prove to be a boon for exchanges as they’ll arguably be in the best position to benefit from any positive market moves.
Where can I watch the halving take place?The best vantage point would a block explorer, where live updates for new transaction blocks can be found.
Given that the vast majority of countries are currently in the midst of social distancing because of the coronavirus pandemic, it’s unlikely that in-person parties will be held.
But with everyone stuck at home, it’s virtually certain that those with a stake or interest in crypto will be online – from Twitter to Telegram to IRC – waiting for the third-ever bitcoin reward halving to take place.

For someone first starting out as a cryptocurrency investor, finding a trustworthy manual for screening a cryptocurrency’s merits is nonexistent as we are still in the early, Wild West days of the cryptocurrency market. One would need to become deeply familiar with the inner workings of blockchain to be able to perform the bare minimum due diligence.submitted by Kosass to CryptoCurrency [link] [comments]
One might believe, over time, that finding the perfect cryptocurrency may be nothing short of futile. If a cryptocurrency purports infinite scalability, then it is probably either lightweight with limited features or it is highly centralized among a limited number of nodes that perform consensus services especially Proof of Stake or Delegated Proof of Stake. Similarly, a cryptocurrency that purports comprehensive privacy may have technical obstacles to overcome if it aims to expand its applications such as in smart contracts. The bottom line is that it is extremely difficult for a cryptocurrency to have all important features jam-packed into itself.
The cryptocurrency space is stuck in the era of the “dial-up internet” in a manner of speaking. Currently blockchain can’t scale – not without certain tradeoffs – and it hasn’t fully resolved certain intractable issues such as user-unfriendly long addresses and how the blockchain size is forever increasing to name two.
In other words, we haven’t found the ultimate cryptocurrency. That is, we haven’t found the mystical unicorn cryptocurrency that ushers the era of decentralization while eschewing all the limitations of traditional blockchain systems.
“But wait – what about Ethereum once it implements sharding?”
“Wouldn’t IOTA be able to scale infinitely with smart contracts through its Qubic offering?”
“Isn’t Dash capable of having privacy, smart contracts, and instantaneous transactions?”
Those thoughts and comments may come from cryptocurrency investors who have done their research. It is natural for the informed investors to invest in projects that are believed to bring cutting edge technological transformation to blockchain. Sooner or later, the sinking realization will hit that any variation of the current blockchain technology will always likely have certain limitations.
Let us pretend that there indeed exists a unicorn cryptocurrency somewhere that may or may not be here yet. What would it look like, exactly? Let us set the 5 criteria of the unicorn cryptocurrency:
(1) Perfectly solves the blockchain trilemma:
o Infinite scalability
o Full security
o Full decentralization
(2) Zero or minimal transaction fee
(3) Full privacy
(4) Full smart contract capabilities
(5) Fair distribution and fair governance
For each of the above 5 criteria, there would not be any middle ground. For example, a cryptocurrency with just an in-protocol mixer would not be considered as having full privacy. As another example, an Initial Coin Offering (ICO) may possibly violate criterion (5) since with an ICO the distribution and governance are often heavily favored towards an oligarchy – this in turn would defy the spirit of decentralization that Bitcoin was found on.
There is no cryptocurrency currently that fits the above profile of the unicorn cryptocurrency. Let us examine an arbitrary list of highly hyped cryptocurrencies that meet the above list at least partially. The following list is by no means comprehensive but may be a sufficient sampling of various blockchain implementations:
Bitcoin is the very first and the best known cryptocurrency that started it all. While Bitcoin is generally considered extremely secure, it suffers from mining centralization to a degree. Bitcoin is not anonymous, lacks smart contracts, and most worrisomely, can only do about 7 transactions per seconds (TPS). Bitcoin is not the unicorn notwithstanding all the Bitcoin maximalists.
Ethereum is widely considered the gold standard of smart contracts aside from its scalability problem. Sharding as part of Casper’s release is generally considered to be the solution to Ethereum’s scalability problem.
The goal of sharding is to split up validating responsibilities among various groups or shards. Ethereum’s sharding comes down to duplicating the existing blockchain architecture and sharing a token. This does not solve the core issue and simply kicks the can further down the road. After all, full nodes still need to exist one way or another.
Ethereum’s blockchain size problem is also an issue as will be explained more later in this article.
As a result, Ethereum is not the unicorn due to its incomplete approach to scalability and, to a degree, security.
Dash’s masternodes are widely considered to be centralized due to their high funding requirements, and there are accounts of a pre-mine in the beginning. Dash is not the unicorn due to its questionable decentralization.
Nano boasts rightfully for its instant, free transactions. But it lacks smart contracts and privacy, and it may be exposed to well orchestrated DDOS attacks. Therefore, it goes without saying that Nano is not the unicorn.
While EOS claims to execute millions of transactions per seconds, a quick glance reveals centralized parameters with 21 nodes and a questionable governance system. Therefore, EOS fails to achieve the unicorn status.
One of the best known and respected privacy coins, Monero lacks smart contracts and may fall short of infinite scalability due to CryptoNote’s design. The unicorn rank is out of Monero’s reach.
IOTA’s scalability is based on the number of transactions the network processes, and so its supposedly infinite scalability would fluctuate and is subject to the whims of the underlying transactions. While IOTA’s scalability approach is innovative and may work in the long term, it should be reminded that the unicorn cryptocurrency has no middle ground. The unicorn cryptocurrency would be expected to scale infinitely on a consistent basis from the beginning.
In addition, IOTA’s Masked Authenticated Messaging (MAM) feature does not bring privacy to the masses in a highly convenient manner. Consequently, the unicorn is not found with IOTA.
PascalCoin as a Candidate for the Unicorn Cryptocurrency
Please allow me to present a candidate for the cryptocurrency unicorn: PascalCoin.
According to the website, PascalCoin claims the following:
“PascalCoin is an instant, zero-fee, infinitely scalable, and decentralized cryptocurrency with advanced privacy and smart contract capabilities. Enabled by the SafeBox technology to become the world’s first blockchain independent of historical operations, PascalCoin possesses unlimited potential.”
The above summary is a mouthful to be sure, but let’s take a deep dive on how PascalCoin innovates with the SafeBox and more. Before we do this, I encourage you to first become acquainted with PascalCoin by watching the following video introduction:
The rest of this section will be split into 10 parts in order to illustrate most of the notable features of PascalCoin. Naturally, let’s start off with the SafeBox.
Part #1: The SafeBox
Unlike traditional UTXO-based cryptocurrencies in which the blockchain records the specifics of each transaction (address, sender address, amount of funds transferred, etc.), the blockchain in PascalCoin is only used to mutate the SafeBox. The SafeBox is a separate but equivalent cryptographic data structure that snapshots account balances. PascalCoin’s blockchain is comparable to a machine that feeds the most important data – namely, the state of an account – into the SafeBox. Any node can still independently compute and verify the cumulative Proof-of-Work required to construct the SafeBox.
The PascalCoin whitepaper elegantly highlights the unique historical independence that the SafeBox possesses:
“While there are approaches that cryptocurrencies could use such as pruning, warp-sync, "finality checkpoints", UTXO-snapshotting, etc, there is a fundamental difference with PascalCoin. Their new nodes can only prove they are on most-work-chain using the infinite history whereas in PascalCoin, new nodes can prove they are on the most-work chain without the infinite history.”
Some cryptocurrency old-timers might instinctively balk at the idea of full nodes eschewing the entire history for security, but such a reaction would showcase a lack of understanding on what the SafeBox really does.
A concrete example would go a long way to best illustrate what the SafeBox does. Let’s say I input the following operations in my calculator:
5 * 5 – 10 / 2 + 5
It does not take a genius to calculate the answer, 25. Now, the expression “5 \ 5 – 10 / 2 + 5”* would be forever imbued on a traditional blockchain’s history. But the SafeBox begs to differ. It says that the expression “5 \ 5 – 10 / 2 + 5”* should instead be simply “25” so as preserve simplicity, time, and space. In other words, the SafeBox simply preserves the account balance.
But some might still be unsatisfied and claim that if one cannot trace the series of operations (transactions) that lead to the final number (balance) of 25, the blockchain is inherently insecure.
Here are four important security aspects of the SafeBox that some people fail to realize:
(1) SafeBox Follows the Longest Chain of Proof-of-Work
The SafeBox mutates itself per 100 blocks. Each new SafeBox mutation must reference both to the previous SafeBox mutation and the preceding 100 blocks in order to be valid, and the resultant hash of the new mutated SafeBox must then be referenced by each of the new subsequent blocks, and the process repeats itself forever.
The fact that each new SafeBox mutation must reference to the previous SafeBox mutation is comparable to relying on the entire history. This is because the previous SafeBox mutation encapsulates the result of cumulative entire history except for the 100 blocks which is why each new SafeBox mutation requires both the previous SafeBox mutation and the preceding 100 blocks.
So in a sense, there is a single interconnected chain of inflows and outflows, supported by Byzantine Proof-of-Work consensus, instead of the entire history of transactions.
More concretely, the SafeBox follows the path of the longest chain of Proof-of-Work simply by design, and is thus cryptographically equivalent to the entire history even without tracing specific operations in the past. If the chain is rolled back with a 51% attack, only the attacker’s own account(s) in the SafeBox can be manipulated as is explained in the next part.
(2) A 51% Attack on PascalCoin Functions the Same as Others
A 51% attack on PascalCoin would work in a similar way as with other Proof-of-Work cryptocurrencies. An attacker cannot modify a transaction in the past without affecting the current SafeBox hash which is accepted by all honest nodes.
Someone might claim that if you roll back all the current blocks plus the 100 blocks prior to the SafeBox’s mutation, one could create a forged SafeBox with different balances for all accounts. This would be incorrect as one would be able to manipulate only his or her own account(s) in the SafeBox with a 51% attack – just as is the case with other UTXO cryptocurrencies. The SafeBox stores the balances of all accounts which are in turn irreversibly linked only to their respective owners’ private keys.
(3) One Could Preserve the Entire History of the PascalCoin Blockchain
No blockchain data in PascalCoin is ever deleted even in the presence of the SafeBox. Since the SafeBox is cryptographically equivalent to a full node with the entire history as explained above, PascalCoin full nodes are not expected to contain infinite history. But for whatever reason(s) one may have, one could still keep all the PascalCoin blockchain history as well along with the SafeBox as an option even though it would be redundant.
Without storing the entire history of the PascalCoin blockchain, you can still trace the specific operations of the 100 blocks prior to when the SafeBox absorbs and reflects the net result (a single balance for each account) from those 100 blocks. But if you’re interested in tracing operations over a longer period in the past – as redundant as that may be – you’d have the option to do so by storing the entire history of the PascalCoin blockchain.
(4) The SafeBox is Equivalent to the Entire Blockchain History
Some skeptics may ask this question: “What if the SafeBox is forever lost? How would you be able to verify your accounts?” Asking this question is tantamount to asking to what would happen to Bitcoin if all of its entire history was erased. The result would be chaos, of course, but the SafeBox is still in line with the general security model of a traditional blockchain with respect to black swans.
Now that we know the security of the SafeBox is not compromised, what are the implications of this new blockchain paradigm? A colorful illustration as follows still wouldn’t do justice to the subtle revolution that the SafeBox ushers. The automobiles we see on the street are the cookie-and-butter representation of traditional blockchain systems. The SafeBox, on the other hand, supercharges those traditional cars to become the Transformers from Michael Bay’s films.
The SafeBox is an entirely different blockchain architecture that is impressive in its simplicity and ingenuity. The SafeBox’s design is only the opening act for PascalCoin’s vast nuclear arsenal. If the above was all that PascalCoin offers, it still wouldn’t come close to achieving the unicorn status but luckily, we have just scratched the surface. Please keep on reading on if you want to learn how PascalCoin is going to shatter the cryptocurrency industry into pieces. Buckle down as this is going to be a long read as we explore further about the SafeBox’s implications.
Part #2: 0-Confirmation Transactions
To begin, 0-confirmation transactions are secure in PascalCoin thanks to the SafeBox.
The following paraphrases an explanation of PascalCoin’s 0-confirmations from the whitepaper:
“Since PascalCoin is not a UTXO-based currency but rather a State-based currency thanks to the SafeBox, the security guarantee of 0-confirmation transactions are much stronger than in UTXO-based currencies. For example, in Bitcoin if a merchant accepts a 0-confirmation transaction for a coffee, the buyer can simply roll that transaction back after receiving the coffee but before the transaction is confirmed in a block. The way the buyer does this is by re-spending those UTXOs to himself in a new transaction (with a higher fee) thus invalidating them for the merchant. In PascalCoin, this is virtually impossible since the buyer's transaction to the merchant is simply a delta-operation to debit/credit a quantity from/to accounts respectively. The buyer is unable to erase or pre-empt this two-sided, debit/credit-based transaction from the network’s pending pool until it either enters a block for confirmation or is discarded with respect to both sender and receiver ends. If the buyer tries to double-spend the coffee funds after receiving the coffee but before they clear, the double-spend transaction will not propagate the network since nodes cannot propagate a double-spending transaction thanks to the debit/credit nature of the transaction. A UTXO-based transaction is initially one-sided before confirmation and therefore is more exposed to one-sided malicious schemes of double spending.”
Phew, that explanation was technical but it had to be done. In summary, PascalCoin possesses the only secure 0-confirmation transactions in the cryptocurrency industry, and it goes without saying that this means PascalCoin is extremely fast. In fact, PascalCoin is capable of 72,000 TPS even prior to any additional extensive optimizations down the road. In other words, PascalCoin is as instant as it gets and gives Nano a run for its money.
Part #3: Zero Fee
Let’s circle back to our discussion of PascalCoin’s 0-confirmation capability. Here’s a little fun magical twist to PascalCoin’s 0-confirmation magic: 0-confirmation transactions are zero-fee. As in you don’t pay a single cent in fee for each 0-confirmation! There is just a tiny downside: if you create a second transaction in a 5-minute block window then you’d need to pay a minimal fee. Imagine using Nano but with a significantly stronger anti-DDOS protection for spam! But there shouldn’t be any complaint as this fee would amount to 0.0001 Pascal or $0.00002 based on the current price of a Pascal at the time of this writing.
So, how come the fee for blazingly fast transactions is nonexistent? This is where the magic of the SafeBox arises in three ways:
(1) PascalCoin possesses the secure 0-confirmation feature as discussed above that enables this speed.
(2) There is no fee bidding competition of transaction priority typical in UTXO cryptocurrencies since, once again, PascalCoin operates on secure 0-confirmations.
(3) There is no fee incentive needed to run full nodes on behalf of the network’s security beyond the consensus rewards.
Part #4: Blockchain Size
Let’s expand more on the third point above, using Ethereum as an example. Since Ethereum’s launch in 2015, its full blockchain size is currently around 2 TB, give or take, but let’s just say its blockchain size is 100 GB for now to avoid offending the Ethereum elitists who insist there are different types of full nodes that are lighter. Whoever runs Ethereum’s full nodes would expect storage fees on top of the typical consensus fees as it takes significant resources to shoulder Ethereum’s full blockchain size and in turn secure the network. What if I told you that PascalCoin’s full blockchain size will never exceed few GBs after thousands of years? That is just what the SafeBox enables PascalCoin to do so. It is estimated that by 2072, PascalCoin’s full nodes will only be 6 GB which is low enough not to warrant any fee incentives for hosting full nodes. Remember, the SafeBox is an ultra-light cryptographic data structure that is cryptographically equivalent to a blockchain with the entire transaction history. In other words, the SafeBox is a compact spreadsheet of all account balances that functions as PascalCoin’s full node!
Not only does the SafeBox’s infinitesimal memory size helps to reduce transaction fees by phasing out any storage fees, but it also paves the way for true decentralization. It would be trivial for every PascalCoin user to opt a full node in the form of a wallet. This is extreme decentralization at its finest since the majority of users of other cryptocurrencies ditch full nodes due to their burdensome sizes. It is naïve to believe that storage costs would reduce enough to the point where hosting full nodes are trivial. Take a look at the following chart outlining the trend of storage cost.
As we can see, storage costs continue to decrease but the descent is slowing down as is the norm with technological improvements. In the meantime, blockchain sizes of other cryptocurrencies are increasing linearly or, in the case of smart contract engines like Ethereum, parabolically. Imagine a cryptocurrency smart contract engine like Ethereum garnering worldwide adoption; how do you think Ethereum’s size would look like in the far future based on the following chart?
Ethereum’s future blockchain size is not looking pretty in terms of sustainable security. Sharding is not a fix for this issue since there still needs to be full nodes but that is a different topic for another time.
It is astonishing that the cryptocurrency community as a whole has passively accepted this forever-expanding-blockchain-size problem as an inescapable fate.
PascalCoin is the only cryptocurrency that has fully escaped the death vortex of forever expanding blockchain size. Its blockchain size wouldn’t exceed 10 GB even after many hundreds of years of worldwide adoption. Ethereum’s blockchain size after hundreds of years of worldwide adoption would make fine comedy.
Part #5: Simple, Short, and Ordinal Addresses
Remember how the SafeBox works by snapshotting all account balances? As it turns out, the account address system is almost as cool as the SafeBox itself.
Imagine yourself in this situation: on a very hot and sunny day, you’re wandering down the street across from your house and ran into a lemonade stand – the old-fashioned kind without any QR code or credit card terminal. The kid across you is selling a lemonade cup for 1 Pascal with a poster outlining the payment address as 5471-55. You flip out your phone and click “Send” with 1 Pascal to the address 5471-55; viola, exactly one second later you’re drinking your lemonade without paying a cent for the transaction fee!
The last thing one wants to do is to figure out how to copy/paste to, say, the following address 1BoatSLRHtKNngkdXEeobR76b53LETtpyT on the spot wouldn’t it? Gone are the obnoxiously long addresses that plague all cryptocurrencies. The days of those unreadable addresses will be long gone – it has to be if blockchain is to innovate itself for the general public. EOS has a similar feature for readable addresses but in a very limited manner in comparison, and nicknames attached to addresses in GUIs don’t count since blockchain-wide compatibility wouldn’t hold.
Not only does PascalCoin has the neat feature of having addresses (called PASAs) that amount to up to 6 or 7 digits, but PascalCoin can also incorporate in-protocol address naming as opposed to GUI address nicknames. Suppose I want to order something from Amazon using Pascal; I simply search the word “Amazon” then the corresponding account number shows up. Pretty neat, right?
The astute reader may gather that PascalCoin’s address system makes it necessary to commoditize addresses, and he/she would be correct. Some view this as a weakness; part #10 later in this segment addresses this incorrect perception.
Part #6: Privacy
As if the above wasn’t enough, here’s another secret that PascalCoin has: it is a full-blown privacy coin. It uses two separate foundations to achieve comprehensive anonymity: in-protocol mixer for transfer amounts and zn-SNARKs for private balances. The former has been implemented and the latter is on the roadmap. Both the 0-confirmation transaction and the negligible transaction fee would make PascalCoin the most scalable privacy coin of any other cryptocurrencies pending the zk-SNARKs implementation.
Part #7: Smart Contracts
Next, PascalCoin will take smart contracts to the next level with a layer-2 overlay consensus system that pioneers sidechains and other smart contract implementations.
In formal terms, this layer-2 architecture will facilitate the transfer of data between PASAs which in turn allows clean enveloping of layer-2 protocols inside layer-1 much in the same way that HTTP lives inside TCP.
· The layer-2 consensus method is separate from the layer-1 Proof-of-Work. This layer-2 consensus method is independent and flexible. A sidechain – based on a single encompassing PASA – could apply Proof-of-Stake (POS), Delegated Proof-of-Stake (DPOS), or Directed Acyclic Graph (DAG) as the consensus system of its choice.
· Such a layer-2 smart contract platform can be written in any languages.
· Layer-2 sidechains will also provide very strong anonymity since funds are all pooled and keys are not used to unlock them.
· This layer-2 architecture is ingenious in which the computation is separate from layer-2 consensus, in effect removing any bottleneck.
· Horizontal scaling exists in this paradigm as there is no interdependence between smart contracts and states are not managed by slow sidechains.
· Speed and scalability are fully independent of PascalCoin.
One would be able to run the entire global financial system on PascalCoin’s infinitely scalable smart contract platform and it would still scale infinitely. In fact, this layer-2 architecture would be exponentially faster than Ethereum even after its sharding is implemented.
All this is the main focus of PascalCoin’s upcoming version 5 in 2019. A whitepaper add-on for this major upgrade will be released in early 2019.
Part #8: RandomHash Algorithm
Surely there must be some tradeoffs to PascalCoin’s impressive capabilities, you might be asking yourself. One might bring up the fact that PascalCoin’s layer-1 is based on Proof-of-Work and is thus susceptible to mining centralization. This would be a fallacy as PascalCoin has pioneered the very first true ASIC, GPU, and dual-mining resistant algorithm known as RandomHash that obliterates anything that is not CPU based and gives all the power back to solo miners.
Here is the official description of RandomHash:
“RandomHash is a high-level cryptographic hash algorithm that combines other well-known hash primitives in a highly serial manner. The distinguishing feature is that calculations for a nonce are dependent on partial calculations of other nonces, selected at random. This allows a serial hasher (CPU) to re-use these partial calculations in subsequent mining saving 50% or more of the work-load. Parallel hashers (GPU) cannot benefit from this optimization since the optimal nonce-set cannot be pre-calculated as it is determined on-the-fly. As a result, parallel hashers (GPU) are required to perform the full workload for every nonce. Also, the algorithm results in 10x memory bloat for a parallel implementation. In addition to its serial nature, it is branch-heavy and recursive making in optimal for CPU-only mining.”
One might be understandably skeptical of any Proof-of-Work algorithm that solves ASIC and GPU centralization once for all because there have been countless proposals being thrown around for various algorithms since the dawn of Bitcoin. Is RandomHash truly the ASIC & GPU killer that it claims to be?
Herman Schoenfeld, the inventor behind RandomHash, described his algorithm in the following:
“RandomHash offers endless ASIC-design breaking surface due to its use of recursion, hash algo selection, memory hardness and random number generation.
For example, changing how round hash selection is made and/or random number generator algo and/or checksum algo and/or their sequencing will totally break an ASIC design. Conceptually if you can significantly change the structure of the output assembly whilst keeping the high-level algorithm as invariant as possible, the ASIC design will necessarily require proportional restructuring. This results from the fact that ASIC designs mirror the ASM of the algorithm rather than the algorithm itself.”
Polyminer1 (pseudonym), one of the members of the PascalCoin core team who developed RHMiner (official software for mining RandomHash), claimed as follows:
“The design of RandomHash is, to my experience, a genuine innovation. I’ve been 30 years in the field. I’ve rarely been surprised by anything. RandomHash was one of my rare surprises. It’s elegant, simple, and achieves resistance in all fronts.”
PascalCoin may have been the first party to achieve the race of what could possibly be described as the “God algorithm” for Proof-of-Work cryptocurrencies. Look no further than one of Monero’s core developers since 2015, Howard Chu. In September 2018, Howard declared that he has found a solution, called RandomJS, to permanently keep ASICs off the network without repetitive algorithm changes. This solution actually closely mirrors RandomHash’s algorithm. Discussing about his algorithm, Howard asserted that “RandomJS is coming at the problem from a direction that nobody else is.”
Link to Howard Chu’s article on RandomJS:
Yet when Herman was asked about Howard’s approach, he responded:
In the end, PascalCoin may have successfully implemented the most revolutionary Proof-of-Work algorithm, one that eclipses Howard’s burgeoning vision, to date that almost nobody knows about. To learn more about RandomHash, refer to the following resources:
Technical proposal for RandomHash:
Someone might claim that PascalCoin still suffers from mining centralization after RandomHash, and this is somewhat misleading as will be explained in part #10.
Part #9: Fair Distribution and Governance
Not only does PascalCoin rest on superior technology, but it also has its roots in the correct philosophy of decentralized distribution and governance. There was no ICO or pre-mine, and the developer fund exists as a percentage of mining rewards as voted by the community. This developer fund is 100% governed by a decentralized autonomous organization – currently facilitated by the PascalCoin Foundation – that will eventually be transformed into an autonomous smart contract platform. Not only is the developer fund voted upon by the community, but PascalCoin’s development roadmap is also voted upon the community via the Protocol Improvement Proposals (PIPs).
This decentralized governance also serves an important benefit as a powerful deterrent to unseemly fork wars that befall many cryptocurrencies.
Part #10: Common Misconceptions of PascalCoin
“The branding is terrible”
PascalCoin is currently working very hard on its image and is preparing for several branding and marketing initiatives in the short term. For example, two of the core developers of the PascalCoin recently interviewed with the Fox Business Network. A YouTube replay of this interview will be heavily promoted.
Some people object to the name PascalCoin. First, it’s worth noting that PascalCoin is the name of the project while Pascal is the name of the underlying currency. Secondly, Google and YouTube received excessive criticisms back then in the beginning with their name choices. Look at where those companies are nowadays – surely a somewhat similar situation faces PascalCoin until the name’s familiarity percolates into the public.
“The wallet GUI is terrible”
As the team is run by a small yet extremely dedicated developers, multiple priorities can be challenging to juggle. The lack of funding through an ICO or a pre-mine also makes it challenging to accelerate development. The top priority of the core developers is to continue developing full-time on the groundbreaking technology that PascalCoin offers. In the meantime, an updated and user-friendly wallet GUI has been worked upon for some time and will be released in due time. Rome wasn’t built in one day.
“One would need to purchase a PASA in the first place”
This is a complicated topic since PASAs need to be commoditized by the SafeBox’s design, meaning that PASAs cannot be obtained at no charge to prevent systematic abuse. This raises two seemingly valid concerns:
· As a chicken and egg problem, how would one purchase a PASA using Pascal in the first place if one cannot obtain Pascal without a PASA?
· How would the price of PASAs stay low and affordable in the face of significant demand?
With regards to the chicken and egg problem, there are many ways – some finished and some unfinished – to obtain your first PASA as explained on the “Get Started” page on the PascalCoin website:
More importantly, however, is the fact that there are few methods that can get your first PASA for free. The team will also release another method soon in which you could obtain your first PASA for free via a single SMS message. This would probably become by far the simplest and the easiest way to obtain your first PASA for free. There will be more new ways to easily obtain your first PASA for free down the road.
What about ensuring the PASA market at large remains inexpensive and affordable following your first (and probably free) PASA acquisition? This would be achieved in two ways:
· Decentralized governance of the PASA economics per the explanation in the FAQ section on the bottom of the PascalCoin website (https://www.pascalcoin.org/)
· Unlimited and free pseudo-PASAs based on layer-2 in the next version release.
“PascalCoin is still centralized after the release of RandomHash”
Did the implementation of RandomHash from version 4 live up to its promise?
The official goals of RandomHash were as follow:
(1) Implement a GPU & ASIC resistant hash algorithm
(2) Eliminate dual mining
The two goals above were achieved by every possible measure.
Yet a mining pool, Nanopool, was able to regain its hash majority after a significant but a temporary dip.
The official conclusion is that, from a probabilistic viewpoint, solo miners are more profitable than pool miners. However, pool mining is enticing for solo miners who 1) have limited hardware as it ensures a steady income instead of highly profitable but probabilistic income via solo mining, and 2) who prefer convenient software and/or GUI.
What is the next step, then? While the barrier of entry for solo miners has successfully been put down, additional work needs to be done. The PascalCoin team and the community are earnestly investigating additional steps to improve mining decentralization with respect to pool mining specifically to add on top of RandomHash’s successful elimination of GPU, ASIC, and dual-mining dominance.
It is likely that the PascalCoin community will promote the following two initiatives in the near future:
(1) Establish a community-driven, nonprofit mining pool with attractive incentives.
(2) Optimize RHMiner, PascalCoin’s official solo mining software, for performance upgrades.
A single pool dominance is likely short lived once more options emerge for individual CPU miners who want to avoid solo mining for whatever reason(s).
Let us use Bitcoin as an example. Bitcoin mining is dominated by ASICs and mining pools but no single pool is – at the time of this writing – even close on obtaining the hash majority. With CPU solo mining being a feasible option in conjunction with ASIC and GPU mining eradication with RandomHash, the future hash rate distribution of PascalCoin would be far more promising than Bitcoin’s hash rate distribution.
PascalCoin is the Unicorn Cryptocurrency
If you’ve read this far, let’s cut straight to the point: PascalCoin IS the unicorn cryptocurrency.
It is worth noting that PascalCoin is still a young cryptocurrency as it was launched at the end of 2016. This means that many features are still work in progress such as zn-SNARKs, smart contracts, and pool decentralization to name few. However, it appears that all of the unicorn criteria are within PascalCoin’s reach once PascalCoin’s technical roadmap is mostly completed.
Based on this expository on PascalCoin’s technology, there is every reason to believe that PascalCoin is the unicorn cryptocurrency. PascalCoin also solves two fundamental blockchain problems beyond the unicorn criteria that were previously considered unsolvable: blockchain size and simple address system. The SafeBox pushes PascalCoin to the forefront of cryptocurrency zeitgeist since it is a superior solution compared to UTXO, Directed Acyclic Graph (DAG), Block Lattice, Tangle, and any other blockchain innovations.

In this article, we will talk in detail about the Bitcoin halving, find out what it is, analyze how this event affected the market previously, study the theories of top traders and try to understand what to expect in the future. So, first things first.submitted by neironixio to u/neironixio [link] [comments]
Inflation?The mysterious Bitcoin creator Satoshi Nakamoto was a real genius, as he came up with a rather smart solution to maybe the most important problem of any currency - inflation. The current Bitcoin rate inflation is 4% per year, while the US dollar 1,91%, the Indian rupee 5,24%, the Russian ruble 4,33%, etc. However, Bitcoin inflation will continue to decrease until it reaches 0% in 2140.
To begin with, the Bitcoins issue is limited, in total, 21 million coins will be issued. As you know, Bitcoins are not issued by any single centralized authority - they are mined. And by analogy with precious metals, the mining complexity will constantly increase, while the reward for the work done will decrease. The whole thing is the correct implementation of source code, as well as the so-called halving, which means that the miners get half as many coins every four years. Thus, by rough estimates, the last Bitcoin will be mined in May 2140.
What is halving and how does it work?To explain what halving is, let's first understand how Bitcoin works. So, this digital coin is based on blockchain technology, which is a decentralized data accounting book, exact copies of which are located on miner computers around the world.
As you know, each book consists of pages, in our case these are blocks. Each block has its own unique serial number. Miners solve complex mathematical equations to form a new block and receive a reward in the form of coins for the work done. The size of this reward is halved every 210 thousand blocks. Considering that about 144 blocks are mined per day, this event occurs approximately once every four years. This is what is called halving. The short Bitcoin history includes two halvings:
A brief analysis of the first halvingOn the day when the first decrease in the reward for the found block happened, the BTC rate showed a slight movement - the price increased by only 1.7%. But if you look at the big picture, you can see that the asset began to grow several months before this event, and just continued to move up after halving. Thus, the BTC rate increased from 13 to 260 US dollars in just four months.
This was followed by a rollback in price up to $80, but later a real bull race started and lasted until December 2013. At that time, the asset grew to unimaginable values, its rate reached the level of 1150 US dollars. Well, and of course, after such an increase, a tight correction of the price and a protracted bear market followed.
Pay attention to the complexity of the Bitcoin network during this event. The chart below shows, that the hash rate began to increase rapidly a few months before the halving, and the growth did not stop after it.
A brief analysis of the second halvingThe second halving occurred in less than four years - on July 9, 2016. This time, the reward for miners fell to 12.5 BTC. It is important to note that the time between the first and second halvings was 1316 days or 3.6 years. Moreover, if to analyze the data, you can see that the market started an upward movement about 9 months before the event. During this period, the BTC rate rose by 112%, and after the Bitcoin halving, it continued to grow till December 2017 and stopped at around $20,000 per coin.
We can also see how the hash rate increased against the background of the second halving. The chart below shows that the complexity of the Bitcoin network throughout the bear market in 2014-2015 was about the same value, but this figure began to grow rapidly about six months before the halving.
Therefore, the miners' interest in Bitcoin has grown significantly a few months before the event. And just like the previous time, the hash rate of the network continued to grow after halving.
In the run-up to of the third halvingAs we all remember, a rather encouraging 2018 followed the euphoria of 2017, and the rates of all coins fell down to 90% of their peak values. According to technical indicators and the general mood in the market, we can say that the bear flag lasted until April 2, 2019. On this day, the Bitcoin exchange rate rose from $4,100 to almost $5,000, then an upward movement began. Note that this happened 13 months before the upcoming halving.
Further, the BTC rate continued to grow rapidly and reached the level of $14,000 at the end of June, followed by a rollback and the price held at around $10,000 for a long time. But on September 24, 2019, there was a fairly powerful price drop, the rate fell by $1,500 in less than a day, and at the time of this writing, the market price of one BTC coin is $8,200.
Note that the resumption of BTC growth this year was again accompanied by a significant increase in the hash rate. The complexity of the network from April to September has more than doubled, and it continues to increase.
How will halving 2020 affect the price?Many market participants are wondering how will the third halving affect the market situation? Unfortunately, we can’t know the future, we can only analyze the current situation, compare it with historical data and draw certain conclusions.
In this article, we take the theories of two famous traders - Bob Lucas and Sunny Decree. They both analyzed in detail previous halving and made their forecasts regarding the market reaction to the next halving.
Sunny Decree TheoryHe believes that the expectation of a halving will lead to Bitcoin price rise, as it was in previous times. He uses the BLX index to confirm this theory - this is the most complete history of the BTC price on the Internet, this is data actually from its very foundation.
The first cycle until November 2012 (before the first halving) is not so important for us since at that time Bitcoin was still a fairly new concept. Almost no one knew about its existence, and there were not many exchanges where it could be traded. However, we can use the second cycle as a projection for the third, in which we are now. The key role in the formation of new cycles is not in the reduction of inflation itself (that is, the Bitcoin halving), but trading activity in anticipation of it.
Each of these cycles can be divided into several phases:
Now let's move on to the price forecast. The difference between the high of the first and second cycle is about 3600%, between the second and third - 1600-1700%. That is, each time the profit as a percentage goes down, so the third cycle was approximately half weaker than the second. As a result, according to Sunny Decree's theory, projecting the estimated percentage of growth proportionally, we can expect that the next BTC high will be at around $185,000. Using the structure of the third cycle, we can suggest that the peak of the bull market will happen in the summer of 2021.
Bob Lucas theoryNext, let's look at the theory of professional trader Bob Lucas. He analyzes the so-called cycles. In his opinion, the last four-year cycle (which contained 52 weeks in the drop and 153 weeks in growth) came to its end, it took 205 weeks in total.
Bob Lucas believes that the price we saw on December 10, 2018, was the end of this cycle. It is important to understand that the video in which he tells this theory in detail appeared on his channel on April 2, 2019 - on the very day when the market began to grow, so six months later we can notice that he was right in many ways, but not in everything.
So, Bob Lucas says in his video that at the beginning of a new cycle we will see the incredible power that will rapidly push the price to new levels. Lucas noted that at the time of recording the video, a lot of people are beginning to actively buy BTC in hope on rapid growth.
He believed that in April the market was not yet at the stage of the final bull race. He said that there will be growing up to plus or minus $6,000 in the near future, followed by a tough correction that will unsettle many weak investors. In his opinion, during this correction, the price may even update the December bottom, and only after that, a new cycle will begin, which will last about 150 weeks in growth. As for the final price, he does not have a specific figure, but he believes that the rate of the first cryptocurrency will be more than 100 thousand US dollars.
He stated that a hard correction should happen around August 2019, but in fact, it did not happen. Even though he made a mistake with the time frame and the estimated rate of BTC, he predicted the vector of the development of the situation quite correctly. Recent events are an excellent confirmation of this when on September 24, 2019, the BTC rate fell by $1,500 in less than a day. It was the correction Bob Lucas spoke about, but it happened a month later than he expected. Yes, it`s not likely that the rate falls to $3,000, but in current conditions, it is quite realistic to imagine a BTC rate of $6,000. Indeed, many analysts and experts agree that the “bloody Tuesday”, September 24th was not the final fall, it caused the next phase of accumulation of assets, which will take some time.
Neironix research department opinionLet's drop someone else’s opinion and do what professional investors usually do - just take the facts we have and analyze them with a cold head.
But it is important to understand that this article is not a guide to action since the digital coin market is quite unpredictable and it is a rather difficult task to foretell any outcome in advance. Do not invest in cryptocurrencies more than you can afford to lose. If you spend more money than you can effort, then you will not be able to think rationally and survive often storms in this young market. Treat your investments with a cold mind, and then you will succeed.
ConclusionBitcoin has already survived two halvings during its short history, and in less than nine months, we will see another decrease in the reward for miners. If you carefully study the charts, you can see that the BTC rate always grows before the halving. And after it, the market goes into a phase of parabolic growth, it lasts about a year, and then comes the correction and a protracted bear market.
A similar scenario has already been repeated twice and many traders believe that we will see a similar picture in the future, since the next halving should take place in May 2020. We observed a significant increase in the hash rate, the number of wallets, transactions and an increase in the rate of the main cryptocurrency 13 months before this event.
Earlier that we carried a detailed analysis of the current state of the Litecoin cryptocurrency, and also analyzed its behavior against the background of the recent halving that took place on August 5, 2019. If you are interested in this topic, here is a link to our study.
