Bitmain Has Announced the Cloud Mining Platform Hashnest

1, Sep 2014

hashnest-cloud-mining-service

Bitmain, one of the top names among the Bitcoin ASIC miner manufacturers, has announced their acquisition of Hashnest – a cloud mining platform which was originally named Snowball Exchange (Snowball.io). Hashnest’s goal is to operate independently in order to build a reliable, economical and decentralized platform that serves the worldwide mining enthusiasts and hosting operators according to the new owner. Originally Snowball was more of a trade platform where you buy and sell actual hosted miners and popular only in China, but it seems that they are moving to providing hashrate to users that is backed up by a large mining farm(s) and opening to the rest to the world. We are not surprised from this news as we’ve recently discussed that cloud mining is going to become more and more attractive alternative to using physical miners for users that are mining crypto currencies. Do note however that as far as Hashnest is considered it is not regarded as a cloud mining service, but as a platform and there is a difference.

UMISOO, the first operator on Hashnest will provide 4 PHS of hashing power, and plans to start the Round 1 subscription at Beijing Time 22:00pm, 2nd September, 2014 (UCT+8:00 Time Zone). The price is flat at 0.0016 BTC per GHS. Due to the anticipated high demand, each user is limited to a maximum of 1000 GHS by default, though this limit can be increased further. The Round 1 hashrate is generated by AntMiner S2 mining hardware (4000 units) with a maintenance fee of $0.0032424 per GHS per Day. Doing some calculations if you purchase 1 THS hashrate you will currently be earning about 0.01834 BTC per day (about $8.78 USD) and the maintenance fee will be $3.2424 USD or the fee is about 37% of what you earn at the moment. The fee is a bit high, though the price per GHS on the other hand is very attractive compared to what other alternative cloud mining operations are currently offering. Even though doing some long term calculations it would take more than a year for you to just ROI, unless of course there is some significant increase in the Bitcoin price that will cause the fee percentage to get lower as it is calculated in dollar price.

BitMain to Start Shipping AntMiner S3 ASICs on July 10th

bitmain-antminer-s3-asic-miner

BitMain has listed the upcoming ~500 GHS AntMiner S3 Bitcoin ASIC miner on their website based on the new 28nm BM1382 chips that were recently announced. The AntMiner S3 should start shipping from July 10th with a price set at 0.75 BTC, so you can already pre-order your unit if you are interested. The initial effective hash rate for the S2 was announced to be 504 GHS plus/minus 5% and now it seem that Bitmain has lowered it a bit to 478 GHS, though the unit should be overclockable to 500 GHS or more. The power consumption for the 500 GHS hashrate that was previously announced was 390W on wall and now with the official hashrate lowered a bit the power usage is also a bit lower at 366 Watt.

AntMner S3 Final Specifications:
– Hash Rate: 478 GH/s±5%
– Power Consumption: 366 Watt at the wall
– Power Efficiency: 0.77 J/GH on wall
– Power Supply: 12V DC
– Size: 331 mm x 137 mm x 160 mm
– Fans: Two 14038 fans mounted on both front and back ends.
– Operating Temperature: 0 °C to 35 °C
– Complied with: FCC / CE
– Network Connection: Ethernet

Do note that the BitMain AntMiner S3 ships without a PSU. There are 4 PCI-e connectors for +12V DC input, but it apparently needs only two of them to be connected if you are not going to be overclocking the device, so the other two are required only if you do plan to overclock the device.

BitMain Ready to Start Shipping 28nm Bitcoin ASICs

21, Jun 2014

antminer-bm1382-chips

BitMain and their 55nm BM1380 SHA256 ASIC chip and the miners that the company has released based on it are quite popular and now the company has announced that they are ready with their new 28nm ASIC chip – the BM1382. As you can already guess the new chips will be offering higher performance at a lower power consumption, so you can get more powerful miners with the same size and power usage as the previous generation with the help of the new chips. The track record of the company is so far very good thanks to the fact that they are not using pre-orders, but ship from stock and announce products when they are ready for shipping, so you can get them fast at a good price and start hashing right away.

BM1382 has achieved 15.75 Gh/s in hash performance, consuming less than 9.33 W on chip level at 0.75V. This means 0.59 J/GH on chip. If the core voltage is at 0.63V, the efficiency will be 0.40 J/GH on chip. BM1382 will bring the power efficiency of Bitcoin mining industry to a new level which has not been massively achieved before. BM1382 represents a 20% power saving on its previous generation of 55nm chips and nearly 10 times of better physical densification, which will further improve the safety of the decentralized ecosystem.


BitMain BM1382 chip specifications:

– Process Node: 28nm
– Package Type: FCQFN-56
– Packaged Chip Size: 8mm x 8mm
– Number of Cores: 63
– Core Voltage: 0.75 V
– Core Frequency: 250 MHz
– Hash Rate: 15.75 GH/s
– Power Consumption: 0.59 J/GH (chip level, and it can be lower to 0.40J/GH by lowering the core voltage)

The first devices that we already expect to be available, probably by the end of this month, from BitMain based on the new BM1382 ASIC chips will be the AntMiner S3 miners. Devices, that will follow the design of the very popular AntMiner S1 blade miner. According to BitMain each S3 should be using 32 BM1382 chips and be able to provide a hashrate of 504 GHS with a power consumption of about 390W from the wall. So this is close to almost 3 times the hashrate of the old S1 with pretty much the same power consumption, not bad at all, but we also need to see this coupled with an attractive price. The new S3 miners have the potential to become a great option for smaller miners that want to be able to mine Bitcoin or other SHA-256 crypto currencies.


AntMner S3 Specifications:

– Effective Hash Rate: 504 GH/s±5%
– Power Consumption: 390 W on wall
– Power Supply: 4 +12V DC input, PCI-e connectors
– Power Efficiency: 0.77 J/GH on wall
– Size: 331 mm x 137 mm x 160 mm (Dual blades assembled inside a box, including the fans)
– Fans: Two 14038 fans mounted on both front and back ends.)
– Operating Temperature: 0 °C to 35 °C
– Complied with: FCC / CE
– Network Connection: Ethernet

We don’t know what the exact price will be, but considering that the company is able to offer 1 THS miner based on the 55nm older chips for a price of $1850 USD at the moment, the half of that hashrate and smaller and easier to produce new AntMiner S3 ASIC miners should be not more than lets say $750 USD, but that is actually a bit expensive. They need to be sold at a price of about 1 BTC or even less in order to become really more interesting for the users and to offer a foreseeable return of investment and some profit for the miners.
