GMO B2 miner

This week, Japanese Internet giant GMO announced its first bitcoin mining machine, the B2.

According to GMO, the B2 mining machine is the world's first 7nm ASIC chip mining machine, and its chip technology is far superior to Bitmain's Antminer S9 16nm chip mining machine and Samsung DragonMint T1 10nm chip mining machine.

In terms of specific parameters, under the power consumption of 1950W, the computing power of the B2 mining machine can reach 24TH/s (the power consumption ratio is 1TH/81W), far exceeding the 14TH/s of the ant mining machine S9. According to GMO, compared with traditional mining machines, GMO’s mining machine can save 20% of electricity, and the cost of network equipment can be reduced to 1/55.

The B2 mining machine starts to accept pre-orders today and is expected to ship in October.

It is understood that GMO invested nearly 10 billion yen in research and development of this product, so the price is relatively high. The B2 mining machine retails for $1,999 (tax included), while the Antminer S9 sells for only $837.

Masatoshi Kumagai, CEO of GMO, said: "Currently the cryptocurrency mining industry is dominated by China's Bitmain, which accounts for 80% of Bitcoin's computing power, but there is no Japanese company specializing in mining machine manufacturing that can participate. The B2 miner is intended to counter Bitmain.”He said: "We haven't set business criteria like sales targets, but if the rigs don't sell, we can use them for our own mining operations, so I think it's a flawless business with no inventory risk

. We also provide an API (Application Programming Interface) for system monitoring. This interface is compatible with the B2 mining machine and can detect the operating status of the mining machine after it is connected to the network and prevent the mining machine from being stolen.

It is reported that since the end of 2017, GMO’s internal mines have started mining. According to GMO data, the company mined 472 bitcoins and 37 bitcoin cash in the month of May alone. At present, the total hash rate of the GMO mine is 299PH/s, which is higher than the 22PH/s in December 2017. The company said that the computing power of the GMO mine is expected to reach 3000PH/s by the end of the year, a year-on-year increase of 900%.It is unclear how much the GMO company mines, but according to the latest cryptocurrency calculations,。

In addition to GMO, Canaan, whose market share is second only to Bitmain, is also actively developing and putting into production 7nm mining machines. Recently, it has been reported in Canaan’s supply chain that Canaan’s new generation of ASICs is also cast at TSMC, and has jumped from the previous generation’s 16nm to 7nm, and plans to mass-produce it in July. In terms of the use of advanced manufacturing processes, Canaan’s progress is faster than that of its competitor, Bitmain. However, this news has not been confirmed by TSMC (Taiwan's chip foundry).
