Some of you may have read the announcement about a Japanese company getting into mining. At this stage they're just announcing their plans and have started posting what they expect from their hardware. The details are in Japanese which fortunately I can read.
https://twitter.com/AkioHoshi/status/907849396779470848まずマイニング設備から。チップは国内設計、国内製造。モジュール1個で10TH/s。48V直流給電。1システムボードに8モジュール。2ボードで1ブレード。1ラックに8ブレード、1.25PH/s。データセンターは16×35mの床面積で500PH/s。
Beginning with mining hardware. The chip will be developed and manufactured domestically. Each module will be 10TH/s. 48 volts DC. Each system board has 8 modules. Each blade has 2 boards. Each rack takes 8 blades coming to 1.25PH. The Data centre will be 16x35m floor space housing 500PH/S.
Of more interest is their hardware description:
https://www.gmo.jp/news/article/?id=5775ハードウェア
計算性能 10TH/s
消費電力 500W以下
投入マイニングチップ：50,000チップから段階的に増強
設備 ラック、冷房、配電、消防、セキュリティ
電力 再生可能エネルギー（地熱、水力）
Hardware:
Estimated capability: 10TH/S
Electricity consumption: <500WMining chip manufacturing: Stepwise increase to 50,000 chips.
Facilities: Racks, cooling, electricity distribution, fire extinguishers, security.
Electric power: Renewable energy (geothermal, hydroelectric.)
Probably the most interesting aspect is 10TH/s for 500W which would make it class leading efficiency. The website also says they'll be using
7nm technology...
Of course we've heard of great claims of efficiency in hardware from newcomers in the past who have failed to deliver on their promises so at this stage it needs to be taken with a grain of salt.
今後の展開（時期未定）
Future plans (timeframe to be determined)
(１) クラウドマイニング事業
1. Cloud mining operation
Explains cloud mining much like any other operation that they'll be selling.
(２) 次世代マイニングボードの販売
2. Next generation mining board sales
Public sales of their hardware!(３) GMOコイン株式会社への仮想通貨供給
3. Provision of virtual currency to the GMO Coin public company
This appears to be them starting a cryptocurrency exchange under a daughter company to their main one.
TL;DR This established Japanese company is getting into bitcoin mining hardware and is aiming to make class beating efficiency mining hardware that it will eventually be selling to the public, timeframe unknown...
The bitcoin mining world desperately needs something to break the bitmain stranglehold on the global hashrate. Hopefully this is the beginning of something that other companies will do too. This is no new company formed just the mine bitcoin, but then bitmain has been working with mining for a long time now and understands it a lot better than the newcomers. It will be interesting to see if that existing knowhow counts for more than what established companies have to back them.
