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.

Icelandic Sindri Tor Stefansson, who was previously charged with theft of bitcoin mining equipment for more than $ 2 million, was sentenced to 4.5 years in prison. Six of his accomplices also received various prison sentences. This is reported by local media.

In addition, convicts will have to pay more than $ 200,000 in compensation in favor of the affected mining company Advania.

In March 2018, Stefansson and his accomplices committed one of the largest robberies in Iceland's history, stealing more than 600 full-featured mining farms from Bitmain.

Police detained the robbers in the same month. However, in April, Sindri Thor Stefansson managed to escape from Icelandic prison and flew to Stockholm and then to Amsterdam, using cell phone and fake ID.

Less than a week later, police detained Stefansson in Amsterdam, after which he was extradited to Iceland, where he was brought to justice.
