The picture from COINDESK related reports
On Aug. 2, Ethereum Classic Labs (ETC Labs) made an important announcement on ETC blockchain. ETC Labs said due to network attack, Ethereum Classic suffered a reorganization on August 1st. This has been the second attack on the Ethereum Classic Network this year.
Did renting-power cause the problem again?
In this ETC incident, one of the miners mined a large number of blocks offline. When the miner went online, due to its high computing power, and some versions of mining software did not support large-scale blockchain mergers, the consensus failed. Therefore, the entire network was out of sync, which produced an effect similar to a 51% attack. Finally, it caused the reorganization of 3693 blocks, starting at 10904147. The deposit and withdrawal between the exchanges and mining pools had to be suspended for troubleshooting during this period.
Media report shows that the blockchain reorganization may be caused by a miner (or a mining pool) disconnected during mining. Although it has been restored to normal after 15 hours of repair, it does reflect the vulnerability of the Proof of Work (PoW) network: once the computing power of the network is insufficient, the performance of one single mining pool can affect the entire network, which is neither distributed nor secure for the blockchain. Neither does it have efficiency.
At present, most consensus algorithms of blockchains are using PoW, which has been adopted over 10 years. In PoW, each miner solves a hashing problem. The probability to solve the problem successfully is proportional to the ratio of the miner’s hash power to the total hash power of mainnet.
Although PoW has been running for a long time, the attack model against PoW is very straightforward to understand, and has attracted people’s attention for a long time: such an attack, also known as double-spending attack, may happen when an attacker possesses 51% of the overall network hash power. The attacker can roll back any blocks in the blockchain by creating a longer and more difficult chain and as a result, modify the transaction information.
Since hash power can be rented to launch attacks, some top 30 projects have suffered from such attacks. In addition to this interference, the main attack method is through the computing power market such as Nice Hash. Hackers can rent hashpower to facilitate their attacks, which allows the computing power to rise rapidly in a short time and rewrite information. In January of this year, the Ethereum Classic was attacked once, and it was also the case that hackers can migrate computing power from the fiercely competitive Bitcoin and Ethereum, and use it to attack smaller projects, such as ETH Classic.
The picture shows the cost of attacking ETH Classic. It can be seen that it costs only $6,634 to attack ETH Classic for one hour.
The security of one network is no longer limited by whether miners within the main net take more than 51% of the total hash power, rather it is determined by whether the benevolent (non-hackers) miners take more than 51% of the total hash power from the pool of projects that use similar consensus algorithm. For example, the hash power of Ethereum is 176 TH/s and that of Ethereum Classic is 9 TH/s. In this way, if one diverts some hash power from Ethereum (176 TH/s) to Ethereum Classic, then one can easily launch a double-spending attack to Ethereum Classic. The hash power ratio for this attack between the two projects is 9/176 = 5.2%, which is a tiny number.
As one of the top 30 blockchain projects, Ethereum Classic has been attacked several times. Therefore, those small and medium-sized projects with low hash power and up-and-coming future projects are facing great potential risks. This is the reason that many emerging public chain projects abandon PoW and adopt PoS.
Proof of Stake (PoS) can prevent 51% attack but has problems of its own
In addition to PoW consensus, another well-adopted consensus algorithm is Proof of Stake (PoS). The fundamental concept is that the one who holds more tokens has the right to create the blocks. This is similar to shareholders in the stock market. The token holders also have the opportunities to get rewards. The advantages of PoS are: (i) the algorithm avoids wasting energy like that in PoW calculation; and (ii) its design determines that the PoS will not be subjected to 51% hash power attack since the algorithm requires the miner to possess tokens in order to modify the ledger. In this way, 51% attack becomes costly and meaningless.
In terms of disadvantages, nodes face the problem of accessibility. PoS requires a permission to enter the network and nodes cannot enter and exit freely and thus lacks openness. It can easily be forked. In the long run, the algorithm is short of decentralization, and leads to the Matthew effect of accumulated advantages whereby miners with more tokens will receive more rewards and perpetuate the cycle.
More importantly, the current PoS consensus has not been verified for long-term reliability. Whether it can be as stable as the PoW system is yet to be verified. For some of the PoW public chains that are already launched, if they want to switch consensus, they need to do hard fork, which divides communities and carries out a long consensus upgrade and through which Ethereum is undergoing. Is there a safer and better solution?
QuarkChain Provide THE Solution: High TPS Protection + PoSW Consensus
For new-born projects, and some small or medium-sized projects, they all are facing the problem of power attack. For PoW-based chains, there are always some chains with lower hash power than others (ETC vs. ETH, BCH vs BTC), and thus the risk of attack is increased. In addition, the interoperability among the chains, such as cross-chain operation, is also a problem. In response, QuarkChain has designed a series of mechanisms to solve this problem. This can be summed up as a two-layer structure with a calculation power allocation and Proof of Staked Work (PoSW) consensus.
First of all, there is a layer of sharding, which can be considered as some parallel chains. Each sharding chain handles the transactions relatively independently. Such design forms the basis to ensure the performance of the entire system. To avoid security issues caused by the dilution of the hash power, we also have a root chain. The blocks of the root chain do not contain transactions, but are responsible for verifying the transactions of each shard. Relying on the hash power distribution algorithm, the hash power of the root chain will always account for 51% of the net. Each shard, on the other hand, packages their transactions according to their own consensus and transaction models.
Moreover, QuarkChain relies on flexibility that allows each shard to have different consensus and transaction models. Someone who wants to launch a double-spending attack on a shard that is already contained in the root chain must attack the block on the root chain, which requires calling the 51% hash power of the root chain. That is, if there are vertical field projects that open new shards on QuarkChain, even with insufficient hash power, an attacker must first attack the root chain if he or she wants to attack a new shard. The root chain has maintained more than 51% of the network’s hash power, which makes the attack very difficult.
As illustrated in the diagram, if the attacker wants to attack the QuarkChain network, one would need to attack the shard and the root chain simultaneously.
PoW has achieved a high level of decentralization and has been verified for its stability for a long time. Combining PoW with the staking capability for PoS would make use of the advantages of both consensus mechanisms. That is what QuarkChain’s PoSW achieves exactly.
PoSW, which is Proof of Staked Work, is exclusively developed by QuarkChain and runs on shards. PoSW allows miners to enjoy the benefits of lower mining difficulty by staking original tokens (currently it’s 20 times lower). Conversely, if someone malicious with a high hash power and does not stake tokens on QuarkChain, he will be punishable by receiving 20 times the difficulty of the hash power, which increases the cost of attack. If the attacker stakes tokens in order to reduce the cost of attack, he/she needs to stake the corresponding amount of tokens, which may cost even more. Thus, the whole network is more secure.
Taking Ethereum Classics (ETC) as an example, if ETC uses the PoSW consensus, if there was another double-spending attack similar to the one in January, the attacker will need at least 110Th/s hash power or 650320 ETC (worth $3.2 million, and 8 TH/s hash power) to create this attack, which is far greater than the cost of the current attack on the network (8Th/s hash power) and revenue (219500 ETC).
Relying on multiple sets of security mechanisms, QuarkChain ensures its own security, while providing security for new shards and small and medium-sized projects. Its high level of flexibility also allows the projects to support different types of ledger models, transaction models, virtual machines, and token economics. Such great degrees of security and flexibility will facilitate the blockchain ecosystem to accelerate growth of innovative blockchain applications.

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.submitted by coinfly to CoinFly [link] [comments]
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.
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 LineNo 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.

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.

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.
Hi all. I saw this on Quora but for some reason cannot link to it, so have copied it below. I would have preferred to point you to it online but hopefully the text below will suffice. Is this accurate?
How much computing power will be needed to mine 1 bitcoin per day or even half of it?
To mine one whole bitcoin per day
Or even 1/2 of one per day….
In Bitcoin mining, there are at least 7–8 exahashes per second of computing power executing and growing continuously
That is :
7 billion - 8 billion GH/second
The s9 ant miner cost about $7,000. And gets 14 TH/s or 14,000 gh/s
If we assume bitcoin mining consumes 7 billion GH per second (it is most likely 8, 7 just makes calculates into prettier numbers)
And each antminer offers 14 thousand GH per second
Or .0002% of the mining (.000002 x 100%)
And there are 2,000 bitcoin a day:
83.33_ every hour
1.388_ every minute
.02315 every second
You would get .004 BTC a day
You would need 250 S9 antminers
For only 1 btc a day
250 x 7,000 = 1.75 million dollars
Or 875,000$ for half a bitcoin a day, based on hashing
You could still get more or less than the given amounts because it all comes down to chance with hashing.
You could also probably buy equipment that is more efficient with that type of money, the S9 antminer is just the most efficient consumer available mining hardware.
I don’t really like bitcoin all that much, this ridiculous computing is the biggest reason, you could power cities across the world with this energy…. And it’s used for bitcoin instead, the least efficient of all the cryptocurrencies in terms of scalability and transaction speed….

This is the source of much uncertainty in mining because it is difficult to accurately forecast the rate of increase. Dilution reduces a miner’s income while the amount of work is the same.
