Bitmain Technologies Ltd., or Bitmain, is a privately owned company headquartered in Beijing, China, with offices in Shenzhen, Shanghai, Chengdu, Hong Kong, Fuzhou, US, Israel, Netherlands and Switzerland. It is the world's largest designer of ASIC chips for Bitcoin mining. [1] As of October of 2018, the company controls 85% of the BTC mining ASIC market, 35% of the hashing power, and also operates BTC.com and Antpool, two of the largest bitcoin mining pools. [2]
Bitmain has been reported to be highly profitable, [3] and had a net profit of $742.7 million in the first half of 2018, [4] but operating cash flow is negative. [1] The company grew 328.2% annually from 2015 to 2017. [4] Their main business is the sale of mining rigs which accounts for 96% of their revenue, whereas mining crypto currencies brings in another 3% according to the company's financial documents. [5]
Bitmain was founded by Jihan Wu and Micree Zhan in 2013. Prior to founding Bitmain, Wu was a financial analyst and private equity fund manager and Zhan was running DivaIP, a startup that allowed users to stream television to a computer screen via a set-top box. [6] They originally met while Zhan was trying to raise money for the startup, however after discovering Bitcoin and becoming the first person to translate Satoshi Nakamoto's Bitcoin white paper into Chinese, he approached Zhan for help in developing a new ASIC chip capable of mining bitcoin, at which point Bitmain was founded.
In June 2018, Wu told Bloomberg that Bitmain is considering an IPO for producing capital to expand its producing hardware. [7] The company completed its $1 billion pre-IPO registration with the Hong Kong Stock Exchange in August, [8] and filed for IPO in September. [4] [1]
In April of 2017, Bitmain released a blog post "Regarding Recent Allegations Smear Campaigns" responding to Gregory Maxwell's proposal. [9] Gregory Maxwell in his proposal talked about a potential shortcut on the Bitcoin PoW algorithm that can save 20% on energy cost, a method patented by Timo Hanke and Sergio Demian Lerner called AsicBoost and proposed a potential solution. [10] Bitmain in their blog post response confirmed the existence of circuit design for AsicBoost in their ASIC chips but however claim to have only used AsicBoost on testnet and never on mainnet. [9] On October 22 of 2018, Bitmain released a new firmware that activated what they called "Overt AsicBoost" citing the recent trend of new manufacturers of hardware advertising the use of "AsicBoost" as the reason why they're releasing this feature now. This "Overt AsicBoost" works in Antminers using the BM1387 ASIC chip such as the Antminer R4, S9i, S9j, T9 and T9+. [11]
Bitcoin cash (BCH), is a crypto currency and a hardfork of Bitcoin that have been strongly supported by Jihan Wu, one of Bitmain's founder. He have made numerous tweets supporting Bitcoin cash and its community. [12] Bitmain is heavily invested into Bitcoin cash. When Bitmain announced it was going IPO, the price of Bitcoin Cash jumped 20%. [13] In an effort to promote BCH growth, Antpool which Bitmain operates committed themselves to burning 12% of the transactions fees they collect by sending them to empty addresses which they believe will benefit the holder of BCH. [14] Bitmain is also partner and sponsor of BCH Devcon, a hackathon event for BCH. [15]
Bitmain Technologies filed for IPO on September 26th, 2018 with the Hong Kong regulatory agency and released their first public financial statement and ending the speculation on the company's plans at a time where Bitcoin prices have dropped 65% as compared to December 2017 which have hurt mining hardware sale that accounts 96% of their revenue. [16] [17] Bitmain will use a dual class share structure. In Bitmain's case, this means the share held by company's founders would count as 10 votes. [17]
On September 19th 2018, AntPool announced on Facebook that it is going to be an official sponsor of the Houston Rockets for the 2018-2019 NBA season. [18] [19] This is part of AntPool's strategy to bring awareness to the cryptocurrency community and strengthen adoption rates by educating the public. According to Haijiao Li, AntPool's overseas operations manager. [20]
As the cryptocurrency industry around the globe continues to evolve and develop, it is going to be more and more important for companies like AntPool to lead the conversation and conversion of consumers to adopt and understand digital currencies. It is an exciting time, and we welcome Rockets fans and those traveling to Houston to visit our showcase at Toyota Center and learn more about the technology that will change the world.

Bitmain releases a wide range of products. Their first miner, the Antminer S1, used 32 BM1380, a self designed ASIC using the 55nm manufacturing process that manages to deliver 180 GigaHashes/s(GH/s). [21] They have since released many more Antminers with the Antminer S9i where using 189 ASIC chips gets 13-14TH/s using around 1300W of power. [22]
Bitmain produces many different miners from miners, to power supplies, to mining router
Bitmain's first bitcoin miner the Antminer S1 was a duel blade machine using BM1380 chips delivering 2 W/GH/s from the wall. [23] On September 21, 2018, Bitmain announces the BM1391 ASIC chip to be used in their next SHA256 miners. The new chip will be using 7nm Finfet process as opposed to the 16nm one used in the S9 according to Bitmain's blog post. [24] Bitmain is also planning to release a Antminer R4 with the slogan "Bringing Mining Back Home". [25] The R4 is going to be using 126 BM1387 ASIC chip built on the 16nm FinFet technology and will produce 52 dB of noise.
