Company profile

Bitmain 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 us

Bitmain 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 Solution


Now 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: BM1380
The 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 S1

AntMiner 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.

Sales

All 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 U1

AntMiner 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 methods
Currently the official store accepts bitcoin only, however will accept Paypal and credit card in the very near future.

Chip samples for testing

Well, at least if this is a scam, it's better than most.



Care to show a picture of the chip itself?


I propose Josh Zerlan, he's an ultra reliable backbone of the community here!

EDIT: Doesn't look like a scam. Goody good, diversification is always a positive thing. Good luck with this endeavour

Looking forward to some trusted forum members doing some reviews.

Wow,its amazing that these specs sound VERY familiar:

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)

Avalon anyone    

To late either way,28nm is going to drown these  

My guess of the next ASIC name......................The Dung Fly  

Looks to me he is removing the chip (FPGA?). Look at the board on the right, it's already gone there.
No idea why this picture is added in their sales pitch though.

And given all the hook-ups, it's a test board ?
It sure has a lot of options, given all the dip switches and jumpers.

A unedited video on youtube with cgminer running next to it would help to take away the scam ideas.
For now the nice pictures ... are just nice pictures.

I would love to order some ants from you.
When miners willbe in stock?

Hi BenTuras, you're right it is the testing board, which is pre-made before engineers get the sample chip. The "chip" is The BM1380 chip, but not a FPGA. The chip has not been printed any logo, but a single dot to mark the sequence of the chip corners, as this is the super urgent job for the packaging factory and we want the most is the speed, so we chose print nothing on chip. The engineer is getting the chip on testing board but removing it.  The other board is another testing board. Chip testing plan needs to prepare several testing boards.

We will provide video tonight or tomorrow night. The last night was the first 12 hours we get the chip, we only be able run it on our own testing program after we solved several problems to see BM1380 functioning all right. And the engineers has very urgent  time schedule to solve additional software problems, and I think only tonight or tomorrow they will have time and patience to cooperate with me, a PR guy who cannot help at all, to take a video~ They all only have slept 2 or 3 hours this afternoon, I guess there will be another through night work tonight. I am trying to provide what the community needs to verify us. And we will release datasheet of our chips soon.

Thanks for your answer, please correct the quoted sentence, it's not clear what you mean.

Exactly what I thought, but don't understand why he seems to be correcting me since I also said that the chip is being removed.
A language thing, I am Dutch, he is Asian(?) and we're trying to communicate about electronics

LOL
