Tokyo's technology company GMO Internet introduced the first bitcoin miner, fully developed in Japan, CCN reports.
B2 also proved to be the first miner, which uses 7-nm semiconductor chips, allowing it to gain performance and efficiency advantages over other devices on the market. Antminer S9 from Bitmain uses 16-nm chips, and DragonMint Halong Mining - 10-nm chips, which are produced by Samsung.

GMO considers the release of its own miner as the first step in the competition with Bitmain, which currently accounts for about 80% of ASIC-miners.
Although B2 development took place in Japan, the manufacture of 7-nm chips for new devices is conducted in Taiwan, probably by TSMC, which also supplies Bitmain chips.
B2 will cost $ 1,999, compared to $ 837 for S9, however, by its characteristics it significantly exceeds the flagship product of Bitmain. GMO reports that B2 can reach 24TH / s, versus 14TH / s in S9, with a power consumption of 1950 watts. GMO will begin accepting pre-orders for B2 on June 6, and the first devices will be delivered to the miners in October.
