Company profileBitmain is a Chinese IC design company founded in the first quarter of 2013. Before we incorporated recently, the team has been working closely on varies IC projects for years. We specialize in the design of digital signal processing chips, including Bitcoin mining ASICs. We have offices in Beijing and Shenzhen.
About usBitmain is a team of technologists, venture capitalist, entrepreneur and Bitcoin enthusiast. Our core members have years of ASIC development experience, and have designed and mass produced several digital signal processing ICs. We aim to strengthen the foundation of the bitcoin market by providing more convenience and profit for miners.
Bitmain has not announced before, but there are members who has been long time bitcoiners. We will try our best to quickly deliver innovative and competitive ASIC miner solutions to help the community. The
AntMiner Solution is able to provide the most power effective mining solution today, with competitive prices.
We do not agree some business practice in the community, which is intended to distribute the risk and benefit asymmetrically. We are here to change it.
No preorders have been accepted, and forever we will not accept pre-order before we feel logically 100% percent sure that we can deliver on time. There will be no unexpected waiting and failed/delayed taping-out or any other kind of delaying risks for our customers. The most risky phase of the AntMiner development has gone, but the first batch production and testing is still full of challenge. We will sell only
in stock miners for the first Batch, expected within a week or two.
Product introduction: AntMiner SolutionNow we proudly introduce the AntMiner solutions with BM1380 chip.
According to our initial testing, BM1380 has best power efficiency on today’s Bitcoin mining device market, which draws only 0.68 W/GH/s power at the chip level. Home miners have limited power supply, for example a typical apartment in China has only 30A*220V mains power. The Bitcoin miner in such an apartment can use only 2~4KW power, as the family has to use other equipment (cooking, heating, lighting etc) that uses power. We want to help home miners have TH/s level, which will be helpful for the safety and decentralization of bitcoin network.
1) Chip specs: BM1380The AntMiner Solution uses a BM1380 hashing chip, which has been developed privately over the past 7 months by Bitmain. Bitmain team has been working on it day and night; some of our engineers got sick several times due to overwork. We combined the wisdom of a mature IC design process with several innovative or even aggressive power saving techniques.
Process Node: 55nm
Package Type: QFN56
Packaged Chip Size: 8 mm x 8 mm
Number of Cores: 8
Die size: 12 mm^2
Core Voltage: 0.75V
Core Frequency:196 MHz
Hash Rate: 1.568 GH/s
Power Consumption: 0.68 J/GH (chip level)
Over clocking performance is still to be tested, before that we need modify our software a little bit.
All the specs announced here are initial results subjecting to future adjustment as we have only get the chips in hands for several hours and this is the results of initial testing.2) AntMiner S1AntMiner S1 is a blade style miner. "1" means AntMiner’s Gen-1 chip, and “S” means “Slice”. There are 32 BM1380 chips on a single blade and each blade has 80 ~ 100 GH/s estimated hashing power and consumes 80 ~ 200 Watt power at the wall. It varies as we still need to test the voltage-frequency sets and the different AC/DC efficiency. Two S1 blades can be combined and share a controlling board,
Given the Bitcoin exchange rate equals 300 USD/BTC, 25 BTC per block outout, 0.15$ per kwh electricity, this blade will be profitable to run until the total network hash rate reaches 150 ~ 300PH/s.
Hash rate: 80 ~ 100 GH/s
Power consumption: 80 ~ 200 W on wall
Power supply: 3 +12V DC input
Power efficiency: 1 ~ 2 W/GH/s on wall
Size: 135 mm x 155 mm x 300 mm (Dual blades assembled, with fans or mounting bracket)
Network connection: WIFI / Ethernet Cable
Cooling: 12cm PWM fans and customized heat sank, expected to be very quiet at 25℃ ambient and should be able to test up to 35~40℃ ambient.
SalesAll 1st batch miners will be able to purchase our product at our official online shop once the S1 is in stock and prepared for immediately shipping out.
Remember, we sell miners in stock in the first round sale! There will be quantity discounts, and we only need about one week to produce the first batch.
Sample miners will be sent out to honored community members for verification, f you agree to write an independent review for the community, please PM me ASAP. We will select only a few of request and apology advanced to those who are not sent sample. Tracking number will be provided immediately after shipping.
Price is to be determined.We know that this may be the most concerned question by all the community members who reading this announcement, including us. But with the recently exchange rate fluctuation and the uncertainty in first batch, we can only try to announce the price of the unit as soon as possible, but not now.
Chinese users will be able to pay with RMB via our taobao store, or from resellers.
3) AntMiner U1AntMiner U1 is an USB miner. There is 1 BM1380 chip it, and estimated hashing rate is
at least 1.6 GH/s as what we have already realized, and it will consumes about 1.2 Watt power from the USB port. It will be available nearly the same time as S1 miner.
There will be other types of mining rigs using BM1380 chips in the future. We will be developing a 60-chip blade, such as 160 ~ 200 GH/s per blade high density type, or silent type without heat sink.
Payment methodsCurrently the official store accepts bitcoin only, however will accept Paypal and credit card in the very near future.
OthersQuestions are welcomed.
Any business partnership proposals are welcomed. Our email:
info@bitmaintech.comAll the PM will be forwarded and reviewed by two of our core staffs, however we may not promise reply every PM.
Picture show: some pictures we take for community review. I know these are not enough, more pictures and videos will be by provided soon.

How come the price of L3 increased from 1200 to 1800 or so in a matter of days? Its not fair to your usual buyers.
