GMO Internet Group is Launching the New Mining Machine “GMO miner B2” Equipped with ASIC Mining Chips “GMO 72b” Using a Cutting-Edge 7 nm Process Technology: Each mining hardware unit will have a performance of 24 TH/s and achieve a power reduction of 20% max per 1 TH/s

Tokyo, Japan – June 6, 2018 – GMO Internet Group (https://www.gmo.jp/en/ ) is launching GMO miner B2, which is our own high-performance computer for mining (mining machine). We will mass-produce the world’s first mining machine equipped with ASIC mining chips using a cutting-edge 7 nm^*1 process technology. For GMO miner B2 sale, we will accept orders through our website and announce the price on a monthly basis. GMO miner B2s sold in June will be shipped starting at the end of October 2018.

*1 nm: nanometer. 1/1 billion meters. 1/1 million millimeters.

■Features of the mining machine “GMO miner B2” (URL: https://gmominer.z.com/ )

1. ASIC mining chips “GMO 72b” using a cutting-edge 7 nm process technology
Mining machine “GMO miner B2” is equipped with our own ASIC mining chips “GMO 72b” using a cutting-edge 7 nm process technology. GMO 72b is compatible with SHA256, enabling Bitcoin and Bitcoin Cash mining.

2. Each mining hardware unit will have a performance of 24 TH/s: saving space and lightening the burden of installing the mining hardware
Each GMO miner B2 unit will have a performance of 24 TH/s (24 trillion computations per second), and more hash power compared to many of the existing mining machines that are currently available. If we deploy only GMO miner B2 into our mining farms, we will be able to save the space of mining facility and lighten the burden of installing the mining hardware compared to most of the competitors’ mining machines.

3. We can connect up to 32 GMO miner B2s by daisy chain: reduces network equipment cost to as low as 1/55 of the cost of using mining machine from other manufacturers
Usually, the mining machines will need to be connected to network equipment for their connectivity to the Internet and the cost for the network equipment accounts for a large percentage of the total investment cost to start mining. Since our design enables us to connect multiple GMO miner B2s to one network port by utilizing the daisy chain feature to build up a cluster of virtual mining hardware, we can decrease the number of physical cable connections to the network equipment. By connecting GMO miner B2s with daisy chain, we can reduce the network equipment cost to as low as 1/55^*2 of the cost of using mining machine from other manufacturers.

*2 Depends on the performance of network equipment.

4. Power consumption drawing 81 W per 1 TH/s, achieving a massive power reduction of a maximum of 20% compared to mining machine from other manufacturers
GMO miner B2 is a power-saving mining machine with power consumption drawing only 81W per 1 TH/s, achieving a power reduction of a maximum of 20% compared to other major mining machines in the market.

5. Additional features
- Power supply unit (PSU)
* Voltage requirements: 200 V (100-240 V; tentative)
- Supports online update of software
- Online monitoring of mining operations (with API)
- Supports online detection as an anti-theft measure
- Automated temperature sensors
* Adjust hash rate automatically if the abnormal temperature is detected to prevent the machine from overheating
- Customers are able to join the mining pool “GMO POOL”
- 180-day guarantee period (customers will have to pay for the repair after the warranty is expired)

Overview of GMO miner B2 sale

We will sell “GMO miner B2” through our website. We will accept orders through our website and announce the price on a monthly basis. If the amount of orders exceeds the planned supply volume, we may need to determine the purchase right by lottery. GMO Internet Group is launching GMO miner B2s today, which will be sold at USD 1,999 (PSU included) in June and shipped starting at the end of October 2018.

Background of launching GMO miner B2

Cryptocurrency mining requires high-performance mining machines enabling highly sophisticated and intensive computation. Accordingly, GMO Internet Group has been working on research and development of a cutting-edge 7 nm mining chip since September 2017, and now realized its own high-performance mining machine GMO miner B2 equipped with 7 nm mining chip. Now that the mass production of GMO miner B2 is within reach, in addition to introducing some GMO miner B2 to the in-house mining, we will offer the others to potential customers who are planning to mine.
