At current state-of-the-art Bitcoin ASIC miner efficiency, the network hash rate will increase until it hits around 1243 PH/s (1,243,360 TH/s) (difficulty 168 billion)
We know the efficiency of the newest ASICs. Miners will keep adding capacity until their margins are fairly low, say 20% more than their electricity costs. Bitfury's new miner only uses 0.8J/GH (here it uses 1J/GH, but they're underclocking the chips in final devices to reach 0.8J/GH). With an electricity price of $0.1/kWh, that means miners want to make at least $0.12 per kWh spent. 0.8J / GH 1 kWh = 3600000 J So mining for one day at 1 GH/s at 0.8J / GH uses 3600*24*0.8J: 69120J / GH/s for 1 day which, in kWh, is: 0.0192 kWh / GH/s for 1 day so to spend 1 kWh per day we can mine at 1/0.0192 GH/s for 1 day: 1 kWh / 52 GH/s for 1 day Mining at 52 GH/s for 1 day currently makes $78.53 (at the next difficulty of 25.7M). So in order for it to only produce $0.12 (which miners are willing to go down to), network hash rate would have to increase by a factor of 78.53/0.012 = 6544 So at current ASIC efficiency (using Bitfury as an example), the difficulty will increase to 168 billion (168,000M) until miners' margins are 20% (at current BTC prices). This will bring the network hashrate up to 1243 PH/s (1,243,360 TH/s).
Shall I keep my $1600 in bitcoins, or buy a 1 Th/s ASIC miner?
I am very tempted to buy a 1 Th/s ASIC miner, I have had previous mining history with my 5 sapphire 280x GPU's but I have sold all my mining equiptment and unsure whether to hold in BTC or get ASIC! Any advice? Would it be worth buying an ASIC? Will I make my money back?
Multi apartment clustered cryptocurrency mining rig
So you’ve probably just heard all your classes are online. And now you’re trying to sublet your apartment but no one’s gonna take it. So now you’re gonna be paying at least $1000/month for an empty apartment. I have a proposal that can reduce that cost and possibly turn a profit. Firstly, we have a very high risk credit market on our hands. The Federal Reserve has been pumping money into the economy and at some point the US dollar will have to inflate while growth stagnates (aka stagflation). During stagflationary periods in the past the price of non-fiat currencies like gold or silver has skyrocketed. Recently cryptocurrencies have emerged with the same general economic properties of such commodities. Therefore we may see an increase in their values as the Fed keeps pumping more money into the economy. As of now in order to generate enough money per month to pay off rent in South Campus Commons, each apartment would need a Bitcoin rig capable of generating ~2200 TH/s (since you don’t pay for electricity). For the Varsity and View this might have to be higher considering the cost of electricity. This is definitely possible with new ASIC chips that are solely built for the purpose of running Bitcoin hashing algorithms. For other cryptocurrencies (Ethereum, Litecoin, Dogecoin), these rates may be different. But like any good portfolio manager, diversifying our investments will ensure we have a profitable outcome. If enough students come together to construct a Bitcoin mining rig in their apartments we could essentially create a multi apartment clustered miner to be able to generate Bitcoin. On top of that, because campus server resources will be diminished due to online classes, we can in turn utilize that computing power to help mine such cryptocurrencies. As a result we won’t have to find people to sublet our apartments to and won’t have to worry about the financial undertakings associated with it. TL;DR: Corona collectively fucked everyone in the ass and we should build a massive Bitcoin rig to pay off our rent.

Author: Gamals Ahmed, CoinEx Business Ambassador https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704 A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it. Filecoin announced, that there will be more delays before its main network is officially launched. Filecoin developers postponed the release date of their main network to late July to late August 2020. As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process. Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market. Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors. The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020. They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit. The Filecoin team noted the following: “We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks. Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet. The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020. The updates to the project can be found on the Filecoin Road Map. Filecoin developers stated: “This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage. Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain. In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards. Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21. Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price. Mining in Filecoin In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency. Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data. Filecoin will contain several types of miners: Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out. Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power. Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network. The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into. In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.
The current system specifications recommended for running the miner are:
NVIDIA-manufactured GPU (to be expanded).
SSD drive designated as large buffer (512GB +).
Large amount of RAM for data replication account (128GB +)
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars. Proceed to mining Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract. Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually. After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started. Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page. At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention. Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt. Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network. Duration of operation, cutting and penalties “Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network. In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error. Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily. An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection. The sector will pay an error fee after the penalty of the sector once the error is discovered. Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network. Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function. Filecoin miners Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.” With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices. Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless. Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers. Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network. However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners. These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB). Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development. “Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital. “Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said. Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT. In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive. To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day. As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force. The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million. This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs. After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020. The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process? Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance. In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners: The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue. It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown. It seeks to promote mining using Filecoin Discover Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day. Ian Darrow, Head of Operations at Filecoin, commented on the announcement: “Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”. Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more. Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds. In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations. The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested. “The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”. IPFS and Filecoin Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure. IPFS It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live. The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides. Using IPFS In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data. Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service. Using Filecoin The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone. Filecoin, powered by IPFS It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS. Some advantages of sharing Filecoin with IPFS:
Filecoin and IPFS CIDs share hash specifications.
Use libp2p by Filecoin nodes to create secure connections with each other.
Messaging between nodes and cluster propagation is facilitated in Filecoin by libp2p pubsub.
IPLD use for blockchain data structures.
Use Graphsync to transfer data between nodes.
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol. Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated. PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage. In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected. Resources :
The discrepancy between BTC's hashrate and price are extremely suspicious
Assuming fairly efficient ASIC miners, which on average have an efficiency of ~34.5 J/TH: c = Current hashrate = 88,200,000 TH/s e = ASIC Efficiency (average) = 34.5 J/TH a = Average electricity (including industrial and other expenses) = $0.12 USD/kWh b = Current Block Reward = ₿6.25 m = Mining Fee Subsidies = ~₿ 9.5 ∴ price = ~[((c * e)/6,000)(a)] / (b + m) = ~$3864 to produce 1 Bitcoin The actual market price is 138% above the cost of actually producing a Bitcoin. Edit 1: I was an idiot, and forgot that the mining fees were what were collected daily (thanks to u/impleplum, so recalculating, it costs roughly ~$9016 to produce a Bitcoin, making the market value 2% above the cost of production, but Bitcoin Cash still costs $265 to produce, still making it 14% more expensive to mine Bitcoin Cash than the actual market value of it.
Bitcoin: Is this the end of the line for the S9 miner?
Bitcoin mining as an industry has evolved over the years as BTC’s price has. From being able to mine BTC using CPUs to GPUs, FPGAs, and ASICs, the industry has matured with the current hashrate at 124 TH/s with difficulty at 16.8 T [trillion].

08-11 01:54 - 'Canaan's Co-Chairman was 'Out', Chinese BIG3 Bitcoin Miner Makers under Inner Wars' (self.Bitcoin) by /u/CjOnChain removed from /r/Bitcoin within 964-974min
''' [link]1 The Bitcoin miner maker Canaan Creative (NASDAQ: CAN) lately announced that five members of their board are leaving. As told, the terms of office of two directors, namely Jianping Kong and Qifeng Sun, expired on July 31, and three of its independent directors, namely Hong Zhang, Xiaohu Yang and Mei Luo, expired on August 1. It is noteworthy that all the departing directors are not allowed to seek appointments nor participate in the elections of the board of directors after the expiration of their terms of office. On July 9, Canaan Creative’s Hangzhou headquarter underwent business registration record modification. Former directors Kong, Sun and Li Jiaxuan, as well as supervisor Tu Songhua withdrew from the board, and Meng Lu was added as the new supervisor. "The corporate contact person also changed from Zhang Jing to Zhang Ning. According to the news, recently, the founder Zhang Nangeng had come with some Canaan Creative executives from Beijing to Hangzhou, dismissed a number of managers of Hangzhou headquarter, took away the official seal and business license of the company, later that day, some employees called the police. [link]2 The same as Bitmain, the first NASDAQ listed Bitcoin miner maker Canaan Creative also built the VIE structure, the main body of the company set up in the Cayman Islands. According to some sources, there has been a power struggle in Canaan Creative, between Zhang’s Beijing office and Kong’s Hangzhou office. In response to what happened in Hangzhou, Canaan Creative said that, "after the registration modification, the company is running normally, and all subsidiaries in China are headed by Zhang as the company's executive director, general manager and legal representative”. The power struggle in Canaan is not a single case. As the former industry dominant, BitMain technologies, who has released IPO prospectus in 2018 but with no progress, stuck in a Cayman Islands lawsuit between two founders. Its business is also badly affected. While another rising star MicroBT’s founder suffered from the disaster behind bars. December 12, 2019, Shenzhen Nanshan Court announced that the criminal suspect Yang Zhenxing was arrested by the crime of official encroachment. Outpost OnChain confirmed the news with MicroBT at the first moment. [link]3 Dr. Yang was graduated from Tsinghua University, had been the former miner chip design supervisor in BitMain and worked for the mysterious miner maker ‘FriedCat’. He had designed so-called BE300 chip using a "full custom methodology", the chip failed to go into mass production with the disappearance of FriedCat. Yang disclosed the "Full Custom Methodology” to the founder of BitMain, Zhan Ketuan, which can significantly reduce the cost and power consumption of the chip. Yang worked part-time to help design the S7 miner (1385 chip) and the S9 miner (1385 chip) that made BitMain's mining dominance possible. In 2016, Yang left BitMain and built up Shenzhen MicroBT Electronic Technology Company. Subsequently, MicroBT released a number of high-performance crypto mining products, quickly squeezed into the market, which had shaken the market dominance of BitMain. Later on, BitMain launched a patent ownership and infringement dispute lawsuit against MicroBT. However, a source said that there are some hidden facts behind Yang's arrest. As the source acknowledged, during the end of 2019, the lawsuit between BitMain and MicroBT made significant progress, law enforcement officers from Beijing has come to Shenzhen to handle the case. Right at this point, as the chairman, general manager and the actual beneficiary of MicroBT, Yang arrested by a 100 thousands RMB worth embezzlement case. The case between BitMain suspended after that. The timeliness of the embezzlement case and the identity of the informer are worthy of considering. Satoshi Nakamoto may not have imagined the emergence of ASIC chips when he published the Bitcoin white paper. The mining machine, a money-printing artifact, has created wealth for mining giants such as BitMain, MicroBT and Canaan Creative in just a few years. While the rapid accumulation of wealth, pathetic stories have also been staged, from the vanish of the FriedCat to the BitMain’s official seal wresting case. The road less traveled may not be the right path for everyone.

Thoughts on if/how this may affect price? https://ih.advfn.com/stock-market/NASDAQ/marathon-patent-MARA/stock-news/82423475/marathon-patent-group-announces-purchase-of-700-ne Marathon Patent Group, Inc. (NASDAQ:MARA) ("Marathon" or "Company"), one of the few Nasdaq listed cryptocurrency mining companies in the United States, today announced the purchase of 700 next generation M30S+ ASIC Miners from MicroBT. The 700 miners produce 80/Th and will generate 56 PH/s (petahash) of hashing power, compared to companies current S-9 production of 46 PH/s. These next generation MicroBT ASIC miners are markedly more energy efficient than our existing S-9 Bitmain models. The company paid $1,277,455 and the purchase was funded with cash on hand. The company expects to take delivery at our Hosting Facility by the end of May and our hosting partner, Compute North, expects to install them within 48 hours of their arrival. The M30S+ is one of the latest generations of bitcoin (“BTC”) Application Specific Integrated Circuit (“ASIC”) miners from MicroBT. It can achieve 100 TH/s at 34J/T and has already proven to be highly stable. The units come with a 1-year warranty versus the industry standard 6-month warranty.
Antminer T19 May Not Affect Bitcoin Hash Rate but Keeps Bitmain Ahead
The Antminer T19 by Bitmain may not have a big impact on the Bitcoin network, and it comes out amid the firm’s internal and post-halving uncertainty. Earlier this week, Chinese mining-hardware juggernaut Bitmain unveiled its new product, an application-specific integrated circuit called Antminer T19. The Bitcoin (BTC) mining unit is the latest to join the new generation of ASICs — state-of-the-art devices designed to mitigate increased mining difficulty by maximizing the terahashes-per-second output. The Antminer T19 announcement comes amid the post-halving uncertainty and follows the company’s recent problems with its S17 units. So, can this new machine help Bitmain to reinforce its somewhat hobbled position in the mining sector? T19: The cheaper S19 According to the official announcement, the Antminer T19 features a mining speed of 84 TH/s and a power efficiency of 37.5 joules per TH. The chips used in the new device are the same as those equipped in the Antminer S19 and S19 Pro, though it uses the new APW12 version of the power supply system that allows the device to start up faster. Bitmain usually markets its Antminer T devices as the most cost-effective ones, while the S-series models are presented as the top of the line in terms of productivity for their respective generation, Johnson Xu — the head of research and analytics at Tokensight — explained to Cointelegraph. According to data from F2Pool, one of the largest Bitcoin mining pools, Antminer T19s can generate $3.97 of profit each day, while Antminer S19s and Antminer S19 Pros can earn $4.86 and $6.24, respectively, based on an average electricity cost of $0.05 per kilowatt-hour. Antminer T19s, which consume 3,150 watts, are being sold for $1,749 per unit. Antminer S19 machines, on the other hand, cost $1,785 and consume 3,250 watts. Antminer S19 Pro devices, the most efficient of three, are considerably more expensive and go for $2,407. The reason Bitmain is producing another model for the 19 series is due to what is known as "binning" chips, Marc Fresa — the founder of mining firmware company Asic.to — explained to Cointelegraph: “When chips are designed they are meant to achieve specific performance levels. Chips that fail to hit their target numbers, such as not achieving the power standards or their thermal output, are often ‘Binned.’ Instead of throwing these chips in the garbage bin, these chips are resold into another unit with a lower performance level. In the case of Bitmain S19 chips that don’t make the cutoff are then sold in the T19 for cheaper since they do not perform as well as the counterpart.” The rollout of a new model “has nothing to do with the fact that machines are not selling well,” Fresa went on to argue, citing the post-halving uncertainty: “The biggest reason machines probably are not selling as well as manufacturers would like is because we are on a bit of a tipping point; The halving just happened, the price can go anyway and the difficulty is continuing to drop.” Product diversification is a common strategy for mining hardware producers, given that customers tend to aim for different specifications, Kristy-Leigh Minehan, a consultant and the former chief technology officer of Genesis Mining, told Cointelegraph: “ASICs don’t really allow for one model as consumers expect a certain performance level from a machine, and unfortunately silicon is not a perfect process — many times you’ll get a batch that performs better or worse than projected due to the nature of the materials. Thus, you end up with 5–10 different model numbers.” It is not yet clear how efficient the 19-series devices are because they have not shipped at scale, as Leo Zhang, the founder of Anicca Research, summed up in a conversation with Cointelegraph. The first batch of S19 units reportedly shipped out around May 12, while the T19 shipments will start between June 21 and June 30. It is also worth noting that, at this time, Bitmain only sells up to two T19 miners per user “to prevent hoarding.” Hardware problems and competitors The latest generation of Bitmain ASICs follows the release of the S17 units, which have received mostly mixed-to-negative reviews in the community. In early May, Arseniy Grusha, the co-founder of crypto consulting and mining firm Wattum, created a Telegram group for consumers unsatisfied with the S17 units they purchased from Bitmain. As Grusha explained to Cointelegraph at the time, out of the 420 Antminer S17+ devices his company bought, roughly 30%, or around 130 machines, turned out to be bad units. Similarly, Samson Mow, the chief strategy officer of blockchain infrastructure firm Blockstream, tweeted earlier in April that Bitmain customers have a 20%–30% failure rate with Antminer S17 and T17 units. “The Antminer 17 series is generally considered not great,” added Zhang. He additionally noted that Chinese hardware company and competitor Micro BT has been stepping on Bitmain’s toes lately with the release of its highly productive M30 series, which prompted Bitmain to step up its efforts: “Whatsminer gained significant market share in the past two years. According to their COO, in 2019 MicroBT sold ~35% of the network hashrate. Needless to say Bitmain is under a lot of pressure both from competitors and internal politics. They have been working on the 19 series for a while. The specs and price look very attractive.” Minehan confirmed that MicroBT has been gaining traction on the market, but refrained from saying that Bitmain is losing market share as a result: “I think MicroBT is offering option and bringing in new participants, and giving farms a choice. Most farms will have both Bitmain and MicroBT side by side, rather than exclusively host one manufacturer.” “I would say that MicroBT has taken up the existing market share that Canaan has left,” she added, referring to another China-based mining player that recently reported a net loss of $5.6 million in the first quarter of 2020 and cut the price of its mining hardware by up to 50%. Indeed, some large-scale operations seem to be diversifying their equipment with MicroBT units. Earlier this week, United States mining firm Marathon Patent Group announced that it had installed 700 Whatsminer M30S+ ASICs produced by MicroBT. However, it is also reportedly waiting for a delivery of 1,160 Antminer S19 Pro units produced by Bitmain, meaning that it also remains loyal to the current market leader. Will the hash rate be affected? Bitcoin’s hash rate plummeted 30% soon after the halving occurred as much of the older generation equipment became unprofitable due to the increased mining difficulty. That spurred miners to reshuffle, upgrading their current rigs and selling older machines to places where electricity is cheaper — meaning that some of them had to temporarily unplug. The situation has stabilized since, with the hash rate fluctuating around 100 TH/s for the past few days. Some experts attribute that to the start of the wet season in Sichuan, a southwest Chinese province where miners take advantage of low hydroelectricity prices between May and October. The arrival of the new generation of ASICs is expected to drive the hash rate even higher, at least once upgraded units become widely available. So, will the newly revealed T19 model make any impact on the state of the network? Experts agree that it won’t affect the hash rate to a major degree, as it’s a lower output model compared with the S19 series and MicroBT’s M30 series. Minehan said she doesn’t expect the T19 model “to have a huge impact that’s an immediate cause of concern,” as “most likely this is a run of <3500 units of a particular bin quality.” Similarly, Mark D’Aria, the CEO of crypto consulting firm Bitpro, told Cointelegraph: “There isn’t a strong reason to expect the new model to significantly affect the hashrate. It might be a slightly more compelling option to a miner with extraordinarily inexpensive electricity, but otherwise they likely would have just purchased an S19 instead.” Bitmain continues to hold leadership despite internal struggle At the end of the day, manufacturers are always in an arms race, and mining machines are simply commodity products, Zhang argued in a conversation with Cointelegraph: “Besides price, performance, and failure rate, there are not many factors that can help a manufacturer differentiate from the others. The relentless competition led to where we are today.” According to Zhang, as the iteration rate naturally slows down in the future, there will be more facilities using “creative thermal design such as immersion cooling,” hoping to maximize the mining efficiency beyond just using most powerful machines. As for now, Bitmain remains the leader of the mining race, despite having to deal with the largely defunct 17 series and an intensifying power struggle between its two co-founders, Jihan Wu and Micree Zhan, which recently resulted in reports of a street brawl. “Due to its recent internal issues, Bitmain is facing challenges to keep its strong position in the future thus they started to look at other things to expand its industry influences,” Xu told Cointelegraph. He added that Bitmain “will still dominate the industry position in the near future due to its network effect,” although its current problems might allow competitors such as MicroBT to catch up. Earlier this week, the power struggle inside Bitmain intensified even further as Micree Zhan, an ousted executive of the mining titan, reportedly led a group of private guards to overtake the company’s office in Beijing. Meanwhile, Bitmain continues to expand its operations. Last week, the mining company revealed it was extending its “Ant Training Academy” certification program to North America, with the first courses set to launch in the fall. As such, Bitmain seems to be doubling down on the U.S.-based mining sector, which has been growing recently. The Beijing-based company already operates what it classifies as “the world’s largest” mining facility in Rockdale, Texas, which has a planned capacity of 50 megawatts that can later be expanded to 300 megawatts.
Ukraine Diverts Free Nuclear Plant Power For Transaction Processing Operations
Ukraine’s Nuclear Power Plants Are Storing Electricity Surplus Due To The Lower Amounts Of Power Consumption As the crypto world prepares for the third Bitcoin halving, the Ukrainian Ministry of Energy and Environment (MEE) proposed the excess electrical power generated from the power plants to be relocated into processing transactions. Currently, Ukraine has dropped its power consumption drastically, as many businesses are shutting down operations due to the COVID-19 virus outbreak. The MEE suggested transaction processing as a “perfect tool for using leftover electricity, as well as economic and social development.” “Having such excess means we can direct it to various sectors like cryptocurrencies. This way, we would keep the minimal loads on the nuclear power plants, as well as grant the chance of crypto-oriented businesses to receive fresh funds from transaction processing. Also, by directing the power into transaction processing, we are creating an entirely new approach to the world of cryptocurrencies and digital economies,” the Ministry stated. The problem with excess electricity occurs because Ukrainian nuclear power plants have to produce a guaranteed minimum of electricity each month. However, due to widespread energy-consuming businesses shutdowns, the quantity of electric power remains unused. The current power cost per Kilowatt of electricity in Ukraine is around $75/MWh. The news comes amid more countries opening their doors to digital currency transaction processing companies. Recently, the Iranian government gave the “thumbs up” and licensed Turkish transaction processing company iMiner. The license means iMiner would become the largest crypto transaction processor in Iran. iMiner’s license also covers trading and custodial services. The Turkish payment processor is going to facilitate a $7,3 million investment into the mining farm. The farm itself is expected to be able to work with a maximum load of 96,000 terra hash per second (TH/s). Over 6,000 machines would do the computing power. In 2019 alone, the Iranian government gave over 1,000 licenses to both individuals and companies, which process transactions with a reported 148,000 ASIC-based mining rigs. Furthermore, governments, which are usually harder to adopt new technologies, seem to find the benefits of granting transaction processors to works, are now focusing on creating the foundations of their digital economies. Iran, for example, needs a digital economy if a new war conflict with the U.S. arises. Ukraine also sees its geopolitical dependence from Russia and seeks alternative funding routes.
Now you understand what im talking about, seriously 2000 TH/s mining Bitcoin at 2400w (where the latest Antminer S17 is 72Th/s), or mining ETH and the profit is so big that it will cover the miner cost faster then month. And another thing, they using the same hardware to mine multiple currencies which every one of them needs different hardware. Worst thing is that people will loose money, and most likely some of them already did. People think they will get rich after buying this miner, which they will never receive. Their fake products look so bad, their cheapest version ZiBit 2.0 looks like an ATX power supply. https://preview.redd.it/sj7oslyl3cb41.jpg?width=1606&format=pjpg&auto=webp&s=470d5ceb04049cb3b617eb3fa1294e414def0b90 Few things to also note is :
They have support chat on their website. I did send them a message and got response after about 20 minutes. So they told me that they only accept crypto currency, and the products are shipped from United Kingdom. My last line of the chat was "im coming for you you'll be in jail soon ".
When you google miner name, there is few websites coming up describing how great is their product. This most likely is owned websites for this scammer or this is purchased content posts.
Dont forget you can find around new Firmware for example for Z9/Z11 Efudd Firmware,and Hive OS firmwares which can Overclock S9/S15/S17 or Underclock (if your electriciy fee are too expensive), for example my S17 Pro I switched to new firmware (Hive OS) to 36Th/s with 900 Watts power gives me a 2.90 usd/day profit without electricity of course, for Z11 Overclocking without changing PSU from 135 to 150-160Ko/sol. I calculated everything on the basis of 0.15 cens Kw / h. Brand New Miner coming out: ASICminer Zeon Turbo 400,000 Sol/s Equihash Most Profitable Miner in the World.

BIP-23 criticism: Why have we made miners generate new a new merkleroot instead of increase the nonce space to 64bit?
Hi everyone, I'm new to the low-level protocol stuff. Here is my understanding of the scenario, which might be incorrect and hopefully will be corrected: Miners can mutate nonce (32bit) + time (mutates once a second). This allows for 232 (~4million) hashes per second. That's not enough anymore for our ASICs as they perform in the TH/s now rather than MH/s. So we allowed miners to mutate the coinbase transaction, but this requires us to generate a new merkletree. This means that a miner needs to generate a new merkletree every 232 hashes. at 1TH/s The miner must generate a new merkle tree 250,000 per second. TLDR: Is Bitcoin PoW actually sha256 + merkletree generation? And not pure sha256? If I'm correct in asserting that Bitcoin PoW is sha256+merkletree, does this slow the commoditization of ASICs and therefore slow decentralization, as ASICs now must be more complex than if they did SHA256+nonce mutations? Hopefully this was coherent, I'm new to protocol stuff, thanks for reading.
The total computing power now dedicated to securing the bitcoin blockchain has set yet another record.
According to data from mining services operator BTC.com, the average bitcoin mining hash rate over the last two weeks has reached 71.43 quintillion hashes per second (EH/s), up from 64.49EH/s on July 23. The threshold was breached as bitcoin adjusted its mining difficulty at block height 586,672 on Monday 2:52 UTC – that is a 6.94EH/s, or 10.78 percent jump since mid July. Bitcoin mining difficulty is a measure of how hard it is to compete for mining rewards on bitcoin. Just how difficult the bitcoin software makes it to generate new blocks adjusts every 2,016 blocks – approximately every 14 days – to ensure the block production time remains about 10 minutes at the next cycle. Assume this additional 6.9EH/s (or 6.9 million tera hashes per second, TH/s) computing power has all come from powerful ASIC miners, such as Bitmain’s AntMiner S17 or MicroBT’s WhatsMiner M20S, both of which boast a mining rate of around 55TH/s and recently hit the market. That means more than 100,000 top-of-line ASIC miners could have been switched on within the past two weeks. Further, given these products have been sold for at least $2,000 each, this equates to some $200 million in revenue pocketed for major miner makers. The continued interest in bitcoin mining comes at a time when the cryptocurrency’s price appears to be en route to challenging all-time highs, however distantly, and amid the arrival of the rainy season in China, which leads to cheaper hydropower electricity costs in the country’s southwest provinces – a region that is reported to account for 50 percent of the global mining activity, Miners in China estimated earlier this year that bitcoin’s hash rate in the summer would break the level of 70EH/s. To be clear, at several single points of time, bitcoin’s hash rate had already crossed that level in June and even reached 80EH/s around Aug. 1. However, today marks the first time that the two-week average computing power has been able to remain above the 70EH/s threshold. As such, bitcoin’s mining difficulty has also set a new record of nearly 10 trillion.
Amidst this uptick in mining interest, there have been notable changes in the mining market, where top manufacturers are racing to produce more powerful equipment. For instance, in Bitmain’s 2018 initial public offering prospectus, the Beijing-based mining giant claimed it had a 70 percent market dominance. Now, it may be facing serious competition from rival players that some believe are capable of shipping more top-of-line products with better profitability. Michael Zhong, a former mining analyst who now operates mining farms at a startup called Force Mine, told CoinDesk that based on his experience, the production capacity ranking among major Chinese miner makers for their flagship products have changed over the years. Zhong explained that from 2017 to 2018, Bitmain had topped the list with its AntMiner S9 series miners, followed by Canaan’s Avalon 8 series machines. InnoSilicon, Ebang and former Bitmain design director’s MicroBT were all in the third position at the time. But from January to June this year, the delivery capacity ranking has reshuffled, with now MicroBT’s WhatsMiner M20 series at the top, followed by Bitmain’s S17 series miners and then InnoSilicon, Canaan, and Ebang, Zhong added. According to F2pool’s miner profit tracker, Bitmain’s flagship AntMiner S17 Pro ranks third in terms of mining profitability, following BitFury’s Tardis and MicroBT’s WhatsMiner M20S. The cost for WhatsMiner M20S is around $3,000, while that of AntMiner S17 Pro is around $4,000 each, based on the information advertised on the two firms’ websites. Although orders for these flagship machines have queued up until November and December this year, MicroBT’s founder Zuoxing Yang told CoinDesk previously that the bottleneck of production capacity is the availability of chips from suppliers. For example, MicroBT uses 10-nm chips for its M20 series, which are relatively more affordable with a higher level of availability compared to more advanced 7-nm chips used by Bitmain for its AntMiner S17 series equipment. While Bitmain has always been relying on chips supplied by Taiwan Semiconductor Manufacturing Company (TSMC), MicroBT has switched from TSMC to Samsung earlier this year for its flagship products. Both TSMC and Samsung have estimated in their most recent Q2 earnings calls that the demand for cryptocurrency mining chips will come back in the third and the fourth quarter this year.

https://preview.redd.it/vs8b0fpg9id41.jpg?width=1280&format=pjpg&auto=webp&s=7d4a7de2c9b2b712d959b06f4f6e01cbf7e664ca For years now there has been possibilities to increase Bitmain bitcoin miners “antminer” efficiency with custom firmware. It is understandable that Bitmain don’t want their customers to change overclock on their asic miners. OC changes could possibly kill or damage hardware in some cases when chip oc and voltages applied to much. Overclock could kill miner it self or power supply. This is one of the reasons why Bitmain lately locks down their miners firmware, they dont want customers to do any changes on them. The factory settings are standard, whoever is mining for while now. Knows that from some chips you can get better efficiency, just because quality of every chip is not the same. Lately there is been released an upgrade firmware and manual for Antminer S17 from hiveOS. HiveOS is gpu and asic miner monitoring/remote control. They previous firmware for Antminer S9 and T9 has been very successful. We have done review on this firmware also, and the best feature what Bitmain original firmware does not have is auto-chip tuning. It works very well, basically it finds the most optimal chip oc and the voltages to reach best efficiency. https://preview.redd.it/ewt2x2v59id41.jpg?width=1702&format=pjpg&auto=webp&s=008de1118c5721a4844cf90c25e4f1fc72b71b73 We have now also tested the new firmware for Antminer S17, it does perform much better then Bitmain original firmware.OnAntminer S17 53TH/s version , air cooled miner we where able to reach 75TH/su/3300watts. It worked very well and setup is straight forward. It is possible to reach even better performance up to 85 TH/s , but you will need immersion cooling. As with air cooled at 75 th/s our miner chip temperatures where close to 80c at room temperature 15c. Also be careful , Bitmani stock power supply Antminer S17 max power usage is 3500 watts. https://preview.redd.it/vwovczl69id41.jpg?width=1952&format=pjpg&auto=webp&s=211b252bd225b1dc7e35195bc86c823b2e2ad7ad hiveOS asic miner the installation guide :
And now let’s go back to the installation process. There is no universal manual, for S17 and S17 Pro there are 3 versions of stock firmware. Therefore, every particular case has its own manual on the custom firmware installation. Please note, that all the manual steps which involve using BTCTOOLS can be done via ASIC’s web interface (BTCTOOLS is usually used for a large number of devices).
Scan the network using BTC_TOOLS and export the list to csv. From csv, copy the IP list and insert it in ips.ini. In case you don’t have a lot of devices, you can make this list manually. Or use bitmain ipreporter tool.
Go to config.ini and check login and password for the ASIC’s SSH or web interface. If the password for the web interface was changed, the same would be for SSH. Set up FARM_HASH to connect to Hive or API, if necessary.
If the stock firmware of your ASIC is released before 1 July 2019
Flash your devices with a file from the archive “remsigallbefore_2019–07–01.tar.gz”. This can be done via either ASIC’s web interface or BTC_TOOLS in case you have a lot of devices. You will see an error in status, but this is okay — it should be like this at the moment.
Flash the devices with the firmware file. Again, this can be done via either ASIC’s web interface or BTC_TOOLS.
Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.
Stock firmware released from July 2019 to December 2019
Launch “1openssh.cmd” from the archive and wait for the script to be performed. The devices will be rebooted. After the reboot, wait for around 3 minutes.
Wow, what a change. From using shovels to mine for metals & minerals, to using ASIC chips to mine for Bitcoin. Two months later (October 2018), Coingeek is promoting "Squire Mining", which claims that they now have an ASIC miner prototype, that is faster & more efficient than most commonly used crypto miners on the market, and they will deliver them to Coingeek in 2019.
Ryan Gosling is probably disappointed that his photo wasn't included on the team members page.
At this point, the penny stock company "Squire Mining" looks like a nChain shell company, acquired through reverse merger. And it could easily be a pump & dump scam, designed to capture the media hype around "blockchain, Bitcoin, ASICs". Which wouldn't be surprising, given that nChain's Chief Scientist Craig Wright ("Fake Satoshi") is a known fraudster.
A comprehensive review of miner arguments against issuance reduction
First I wanted to start by saying Hudson Jameson did a phenomenal job wrangling all these different stakeholders to the core devs meeting today and playing the part of an effective, neutral moderator. It was a really interesting meeting and great to hear all viewpoints. I'm sure many of you live streamed it as well. I’m an Ethereum investor and active user, and I took notes on the most prominent miner arguments against issuance reduction along with my thoughts on each. Would love to hear any thoughts or any ones I may have missed. GPUs that leave network after issuance reduction can be used to attack Network Security (Xin Xu) Xin Xu argues that a decline in issuance from 3 to 2 (33%) will cause a drop in hashrate by 33%, and that such a large drop in hashrate will lead to an influx of GPUs on the market that can be used to attack Ethereum. This argument is predicated on the idea that hashrate will drop significantly. However, any drop in hashrate will decrease difficulty so mathematically a 33% drop in issuance should have at most a ~18% impact to total hashrate assuming a linear relationship. I don't believe that a drop in Ethereum Network Hashrate from current levels (280 TH/s) to January 2018 levels (230 TH/s) is a doomsday scenario. And the real drop will certainly be much smaller for two reasons. 1) Historical data shows that hashrate is extremely resilient against drops in price as well as issuance (source: https://pbs.twimg.com/media/DlTEyKBV4AERGtB.jpg:large). 2) Historical data also shows that all Ethereum and Bitcoin issuance reductions were followed by price increases which could partially or completely offset the decline in hashrate. Issuance Reduction will drive a dramatic shift in hardware composition of the network (Brian Venturo) Brian Venturo argues that a reduction in issuance will price out GPU miners and cause the network to dramatically shift towards ASIC miners in the short term, increasing mining centralization. However, miners on the call pointed out that currently available ASICS (Antminer E3) is in-line with top GPUs in terms of mining efficiency. It’s only when we compare claims from as-yet unreleased ASIC manufacturers (Innosilicon A10) to 2-year old GPU technology (GTX 1080) that we see any risk of an efficiency gap. Second, the total Ethereum network hashrate is 280 TH/s. This is equivalent to 577,000 Innosilicon A10s, which would cost $3.3 Billion (at $5700 each). Any shift of even 10-20% in Ethereum network hardware composition will be slow and steady, and as we heard on the call, miners looking to spend significant capital on new hardware are considering major ROI headwinds from 1) upcoming shift to PoS and 2) possible exploration of new ASIC-resistant algos like ProgPOW. Both of these would brick current generation ASICS while GPUS would retain their resale value. More work needs to be done exploring ASIC-resistant POW algorithms, and there's no reason why issuance-reduction EIPs should be roadblocked in the interim. EIP 1295 as an alternative (Brian Venturo) Brian Venturo cites the current rules around Uncle and Nephew rewards as causing weird incentives that miners are exploiting to maximize uncle rate and squeeze higher issuance out of the network. This is a super interesting point, and one that I would love to see explored in more detail (as the downstream implications could be quite complex) in addition to EIP-1234. There’s no reason why 1295 is mutually exclusive with EIP-1234, and positioning it that way is a clever tactic to delay any issuance reduction. Brian himself suggested an issuance reduction in 2019 on top of EIP-1295. My Final thought I am in full support of EIP-1234 as a moderate issuance reduction to reduce Ethereum inflation and the amount we are overpaying miners for security. Looking back on it, last year’s 40% reduction from 5 eth/block to 3 eth/block has turned out to be a phenomenally good decision. Since then, hashrates have increased 3x while price has declined 20% (was $330 pre-fork), all while we reduced inflation by 40%. Another modest issuance reduction is a prudent decision that is a natural step in Ethereum’s growth and consistent with the original vision for inflation. In contrast, a difficulty bomb delay without a corresponding issuance reduction should be viewed as an issuance increase. The quicker we can get this decision behind us, the better. As long as this question looms, investors will lack confidence in Ethereum’s monetary policy, and mining stakeholders will have massive incentive to decrease Ethereum price until Constantinople to increase the chance they can mine at inflated rates through 2019
First-time poster here, don’t bully me, apologies for the potentially atrocious formatting :) TL;DR at the end So in the wake of Bitcoin’s explosive rise in value and media attention, I’ve been encouraged by others to share my experience over the past few years as a miner. Here's my story (it's kinda long, you've been warned)
It all started almost three years ago in the beginning of 2015 when Bitcoin flew under my radar. Looking into it, I admittedly wasn’t drawn in because of the decentralisation or the anonymous payments, I was hooked on the idea that anyone could get their hands on some just by running a program and leaving it to do its own thing. I know, how shallow of me. But the idea of making even a bit of money without ‘any work’ was convincing enough for 11-year-old me to do more digging into the matter. To my disappointment, I soon found out that the era of mining Bitcoins with a PC’s CPU or GPU was long obsolete and instead it was all ASICs at that point. So that summer, for my twelfth birthday, I got a little ASIC machine for €60, an Antminer U3. This little thing took up less space than a graphics card but could mine at 60 GH/s. Because, at the time, I didn’t have a controller device that could be kept up and running all day long so it could run the program that mined Bitcoin using the U3, I went ahead and got a Raspberry Pi. After setting up the Pi and installing all the necessary stuff (took an awfully long time), I connected it to AntPool and plugged the U3 in. Two days past and the mining pool sent the first Bitcoin I ever received to my wallet (I was using Blockchain.info). It was just 30 cents worth of BTC but I felt a bit of a rush because I was earning a bit of money through this completely new thing and the idea of that was thrilling. Let’s back up for a second. I just used the term ‘earning’ as if I was profiting, and naive me 2 years ago was no different. In reality, I was at first oblivious to the fact that I was most likely LOSING money overall because of how much energy that little sucker was taking in. But, I was comforted thinking that using that machine was just a practical way of learning about this modern currency and that the loss of several cents’ worth of energy was acceptable in the name of education and learning. Fast forward ten months to the wonderful summer of 2016. I had recently turned 13 and the Antminer U3 had been running on and off throughout. Various pauses and breaks in mining would be observed, as I had to manually get everything up and running after frequent breaks in the Internet connection. You’d expect my newly-turned-teenage brain to lose interest in Bitcoin as it does with many other gimmicks, but – even surprising myself – I miraculously didn’t. Good thing I maintained interest thinking about it now, not so good at the time for my parents. Why do I say this? I felt like it was time to get a little upgrade in my hardware.
Getting an upgrade
Days passed with me comparing every ASIC miner I could at that price point. It was then I set my eyes upon the Antminer S7 (same folks who did my U3, nice). I had put it up against a plethora of other miners and I figured the S7 was my best bet; the thing costs only about 10 times that of my U3 but could run at 4.73 TH/s, almost 80 times as powerful. The only problem being its power consumption was at 1300 watts, which would put a massive dent in the electricity bill and eliminate any profit I would make. Fortunately, I had a secret weapon up my sleeve – or rather my mum did. She had rented out an office outside our apartment where she would keep files and paperwork. The office’s electricity bill was a flat rate as far as I’m aware and it ended up being my saving grace because it virtually got rid of the “oh no I’m actually going to be losing money because of how much electricity I’m eating up” factor, making this whole hardware upgrade viable. After convincing my parents, they finally agreed to shell out the requested amount, with the initial investment being paid back with time. I went to a local Bitcoin vendor and purchased 1 BTC for about $665 in cash (sigh yes, I know. $665 dollars). Shortly after, I used about 0.9 BTC to purchase the Antminer S7 and a 1600W power supply for a grand total of $600. The products would be made and shipped from China so I was definitely in for a wait. A month passes and the package arrives at last. I connected all the wires from the power supply into the S7 and – with great anticipation – I plugged it into the wall to start its first ever run. And what do you know? An extremely loud and high-pitched whirring sound blasted out from the fans on both the power supply as well as the S7. After killing the thing, I questioned my choices. I couldn’t dare put that thing anywhere near my mum’s office in the event it drive everyone in the building absolutely nuts. I was at a loss. However, I soon recovered from my temporarily debilitated state and got working on a solution. The first idea that came to my mind: change the fans. The stocks fans were by Evercool and spun at around 3000 RPM. The power supply used a small, robust fan that looked like a cube that must’ve spun at extremely high speeds judging by how high the sound it produced was. I got my parents to give me some more funding so I could acquire the replacement fans and I did. Bust. After installation and testing, none of the fans would work. I managed to configure the S7 to connect to my Antpool account and the machine would manage mining for several minutes running at peak performance but ultimately be automatically cut off because of how hot the machine was getting (I’m talking about 80 degrees Celsius kinda hot in that thing). The fans got refunded and I was back to the drawing board. After combing through some forum posts and videos, I came across this video and a forum post in which people have their mining rigs placed inside a ventilated, muffled cabinet. Undertaking a project like this would be time-consuming and risky but I had no better ideas so I decided to go through with the idea anyway. Firstly, I sought out a cabinet with suitable dimensions. I managed to get just what I needed at a second-hand IKEA shop. Great. Secondly, I went ahead and acquired some sound-absorbing acoustic foam from a local provider. Fantastic. Finally I had to get a ventilation system going within the cabinet, otherwise, all the hot air would roast the machine alive in there in a bloody mess. With the help of my dad, we found a pair cabinet fans on the Internet that were close to silent but could circulate the air well enough. Eventually, all the materials came and, with the help of my parents, put everything together. The process took quite long time and we had a couple hiccups along the way, but we got it done and it came out pretty nice. The moment of truth came and, to my relief, it ran so much quieter than without the cabinet. It was nowhere near silent but it reduced the noise a great deal. Soon after, I got the thing into the office and set everything up from there. Unfortunately, I was forced to underclock it because you could still hear the machine’s whining from outside the thin office door. Gunning the hashrate down about 25% to 3.7TH/s, I could lower the fan speed without risking the machine burning up. Sure, I wasn’t getting the full potential of the machine but I didn’t complain because electricity was not an issue there and it was still a whole lot better than my U3. With it up and running, I could leave it there, periodically checking to see if it was mining on Antpool.
In the months that followed, I was getting a solid $2.5 worth of BTC on daily basis. Half a year later, May of 2017, I had accumulated a satisfactory $600. I thought, “At this rate, I’d be able to pay my parents’ investment back in a few months” (the total investment came close to $900). Bitcoin had risen to over $1500 so I was already over the moon at that point because of how well everything was going. Little did I know… I hit 0.5 BTC midway through September this year. The price of BTC had dropped after a sudden rise to $5000, but I couldn’t have asked for more. Although I possessed only half the amount of BTC I paid for the machine, its value was over twice that of the initial investment. I thought BTC would level off at around $4000 but nope. In the month of October, the price skyrocketed. Since September, I had only mined 0.017 BTC but the value was already over $3000. It was just a matter of selling it, but I decided to hodl. Good thing I did. As of November 5, I have approximately 0.52 BTC mined in total from my S7, valued at $4000. If I were to sell it right now, I’d have a profit of over $3100. And as for my miner, it’s churning out 0.0006 BTC daily, sounds like nothing but it’s still the equivalent of $5 today and I couldn’t be happier, at least with the miner and Bitcoin. You remember that $665 for 1 BTC that I mentioned earlier? In hindsight, it would’ve been such a better idea to just keep that one Bitcoin and not do anything with it until today (in the interest of making much more money), as I’d theoretically have upwards of $7000. The idea of that still haunts me sometimes if I dwell on it too long but knowing that I’m in possession of an already hefty amount, the pain of it had numbed slightly. It’s not all doom and gloom for me from the exponential increase in Bitcoin’s value, however. Those first $0.3 payments from my humble little U3 all those years ago now are now the equivalent of over $6 today! Bitcoin and everything it encompasses has been and still is a journey of discovery and an adventure. Looking back, starting with a modest €60 Antminer U3 to having a sum of Bitcoin equivalent to two extremely high-end gaming rigs (first thing I could think of as a comparison, sorry) has been something I can’t really describe. Through the course of the past few years, I’ve learned more about technology, I’ve unexpectedly gotten insight into economics and business and – of course – I’ve made a lot of money (if I decide to stop hodling that is). Also, props to my parents for keeping an open mind throughout, I know some parents would be horrified at their kids being involved in something that has been used in some less-than-savoury ways and it's great knowing mine have been supportive all the way. TL;DR got into Bitcoin mining 3 years ago at age 11 with an Antminer U3 that ran at 60 GH/s, got an Antminer S7 (4.73TH/s) and built a sound-muffling, ventilated cabinet for it. Am sat here today with $3000 profit if I decide to sell right now.
