The undercurrent of Ethereum mining machines is surging, is Bitmain E9 real or fake? At least 10 are ready to enter

Wu said that the blockchain has learned that with the ETH reaching a maximum of around US$620, the Ethereum mining industry has become very frenzied. Rumors of Bitmain’s latest generation of Ethereum mining machines E9 and FPGA Ethereum mining machines are rampant, and at least ten companies are trying to make new Ethereum mining machines.

Bitmain once released the Ethereum mining machine E3 in 2018, which rarely used ASIC chips, and frantically swept the market at high prices. However, due to the sharp drop in currency prices and the immaturity of the mining machine itself, it not only failed to sell well, but instead There is a large backlog of scrap stocks. E5 is an experimental machine.

In July 2020, the monitoring data of the Ant Sentinel website today showed that a mining machine named "E7" was mining, and Bitmain's Ethereum mining machine E7 was exposed. About 500-700M, but no mass production and sales.

Recently, rumors about Bitmain’s Ethereum mining machine E9 are circulating in the market again. Wu said that the blockchain learned that Ketuan Zhan had said in an internal meeting that he would tape out the Ethereum chip in September. However, after Wu Jihan took back the Beijing legal person, this streaming project ended without a problem, but it cannot be ruled out that it will start again after the change of control rights in the future. The information about E9 in the market is likely to be released by Zhan’s sales staff to obtain cash flow by selling futures. The performance of E9 is theoretically twice that of E7, which is amazing.

The core problem with ASIC Ethereum mining machines is not the technology, but the backlash from the community. A veteran of the domestic Ethereum mining machine lamented that fortunately the Antminer E3 was not successful, otherwise the community might have accelerated the conversion from POW to POS, and other graphics card miners would also suffer. Inside Bitmain, there are actually no major technical problems. The main reason is that the community is worried about changing the algorithm, so they choose to produce in small batches and mine by themselves.

At present, Ethereum is starting the first phase of 2.0 from POW to POS. The industry generally believes that it will take about 2 years to complete the transfer, which means that Ethereum miners still have 2 years of mining time, but after the expiration, they can also mine other POW graphics card currencies, such as the recently popular Conflux.

In addition, the DAG of 12 files before and after this year will exceed 4G, which will cause mining machines with 4G video memory to no longer be able to mine Ethereum. These graphics cards may be used for modification or flow out of the mining circle. The power accounts for about 30% of the total network computing power of Ethereum. However, ETC can also be mined. Recently, ETC has changed its algorithm to be compatible with old-fashioned mining machines.

Even so, Ethereum mining machines can pay back multiple times in two years when the currency price is high. The payback cycle of graphics card mining machines is about 10 months, while that of Antminer E7 is 4-5 months. In fact, in 2020, it is very obvious that Ethereum mining is more active than Bitcoin mining. Wu said that there are currently at least 10 companies trying to enter the field of Ethereum mining.

Bitmain's ASIC model has the highest cost and the largest computing power, but it is likely to trigger V God and Ethereum developers to speed up the modification of the algorithm, so many of them are secretly developed by themselves, and mine in their own mines or sell them to familiar ones. big miner. The Ipollo pineapple mining machine invested by Kong Jianping, the former co-chairman of Canaan, or the Ethereum mining machine released belong to this type.

In addition, the current mainstream graphics card customization machine in the industry is the core mining machine A10. According to Zhikuang University, the characteristic of customized machines is that mining machine manufacturers find graphics card manufacturers to produce graphics cards that meet their own requirements. This kind of graphics card generally only retains some functions necessary for mining, and other functions that are not related to mining will be castrated. It is reported that the core movement may also launch the A11 series after the A10. The Wolf God new mining machine is a customized version of AMD GPU, and the Panda mining machine is a conventional GPU mining machine.

The last is the assembled graphics card machine, which generally uses a normal graphics card. Even if it is not used for mining, it can be recycled and used in other industries such as games, with a higher residual value. Generally speaking, for a graphics card that has been mined for two years, the residual value rate is about 30% of the market price of a new graphics card. Another is the rumored Ethereum FPGA mining machine, but there is no mature product available yet.
