I will tell you the content of GMO’s presentation as accurately as possible, and comment at the end. 2018/6/5

Greeting from CEO Mr.Kumagai about releasing the cryptocurrency mining machine.

Bitcoin is the largest invention after the internet came out, but there are two big issues.

1.Chinese mining machines are in most of mining.

It is coming to difficult to say the decentralized society as Satoshi Nakamoto has originally mentioned.

2.Japan doesn’t participate in this field at all despite we have been good at making things.

Today’s purpose is to show the answers for these two questions.

GMO group has been striving for the following until today.

Internet  Eliminate boundary of information

From now GMO are going to work for the following.

Cryptocurrency  Eliminate boundary of money.

We can see that cryptocurrency is gold or currency in only our future, but can’t doubt that it has already the value as gold.

The maximum hash power of other companies have been 14 TH/S.

The merit is to be able to install strong hash power.

Cut installation space in half (Extensive mining farm)

  Cut size of date center in half

Cut working time in half (no need to troublesome setting and verification)

Up to 32 daisy chains can be connected.

The maximum network cost is only 1/55

Although it cost hundreds of millions of yen only with network equipment cost, it can also cut costs.

One unit 1950 w

Power Supply Unit 2200 w  100 – 240 V  200 V Recommended  If 100 V, 24 TH / S cannot be guaranteed.

Latest 7nm process  It’s difficult to secure line. Should have costed a lot.(According to questioner, it might be more than 1 billion yen)

Authors Comment

GMO sells the machine by lottery to show support for decentralization of Bitcoin if the number of orders exceed the number of supplies.
It means even individual has chance to acquire this world best performance mining machine at this moment.

GMO is certainly challenging to solve these two issues as Mr.Kumagai has mentioned.(Top part  of the article)
This is the first ambitious and specific effort to aim the NO.1 in the world with Japanese technology in mining which essential for cryptocurrency.
Also, since GMO has long term experiences as a rental server company, the skill is utilized for managing mining farm.

This latest technology development should have never been easy. In this days, Japan has not getting any attraction in crypto field.
But, this announcement has showed the existence of Japan clearly. I will keep supporting GMO’s bold challenge!
