Wushuo Blockchain learned that as ETH hit a peak of around $620, the Ethereum mining industry was very active. Rumors about Bitmain’s latest generation Ethereum mining machine E9 and FPGA Ethereum mining machine are rampant, and at least ten companies are trying to build new Ethereum mining machines.
Bitmain released the Ethereum mining machine E3 in 2018, which rarely used ASIC chips and purchased products at crazy high prices in the market. 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 also accumulated a large amount of scrap inventory. E5 is an experimental machine.
In July 2020, monitoring data from the Ant Sentinel website today showed that a mining machine named "E7" was mining. This exposed Bitmain’s Ethereum mining machine E7. The highest computing power of a single machine is around 800M, and the other products are around 500-700M, but they have not yet been mass-produced and sold.
Recently, rumors about Bitmain’s Ethereum mining machine E9 have once again circulated in the market. Wushuo Blockchain learned that Ketuan Zhan once stated in an internal meeting that the Ethereum chip will be tape-out in September. However, after Wu Jihan took back the Beijing legal person, this tape-out plan came to an end, but it is not ruled out that it will be restarted after the change of control in the future. The information about E9 in the market was probably released by Zhan’s salesperson with the purpose of obtaining cash flow by selling futures. The performance of E9 is theoretically twice that of E7, which is very amazing.
The core problem with ASIC Ethereum miners is not the technology, but the community backlash. A domestic Ethereum mining machine veteran lamented that fortunately the Antminer E3 did not succeed, otherwise the community might accelerate the conversion from POW to POS, and other graphics card mining machines would also suffer. Within Bitmain, there are actually no major technical problems. The main concern is that the community will change the algorithm, so more people choose to produce in small batches and mine on their own.
Ethereum is currently launching the first phase of 2.0, moving from POW to POS. It is generally believed in the industry that it will take about 2 years to complete the transfer, which means that Ethereum miners still have 2 years of mining time. However, you can also mine other POW graphics coins after expiration, such as those that have become popular recently.
In addition, the DAG of 12 files will exceed 4G around this year, 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 leaked out of the mining industry. According to Zhikuang University, such graphics cards provide computing power. It accounts for approximately 30% of the computing power of the entire Ethereum network. However, ETC can also be mined. Recently, ETC changed its algorithm to be compatible with older miners.
Despite this, Ethereum mining machines can recoup their investment many times within two years when the currency price is high. The investment payback period of a graphics card mining machine is about 10 months, and that of the Antminer E7 is 4-5 months. In fact, it is very obvious that Ethereum mining was more active than Bitcoin mining in 2020. Wu said that Blockchain understands that at least 10 companies are currently trying to enter the Ethereum mining machine manufacturing field.
Bitmain’s ASIC model is the most expensive and has the largest computing power, but it is likely to lead to accelerated algorithm modifications by Ethereum developers. Therefore, many companies develop it secretly, mine it in their own mines, or sell it to companies they are familiar with. Big miner. The Pineapple mining machine invested by Kong Jianping, the former co-chairman of Canaan, or the Ethereum mining machine released fall into this category.
In addition, the current mainstream graphics card customization machine in the industry is the core mining machine A10. According to the Intelligent Mining University, the characteristic of customized machines is that mining machine manufacturers find graphics card processing manufacturers to produce graphics cards that meet their own requirements. This type of graphics card generally only retains some functions necessary for mining, and other functions unrelated to mining will be castrated. It is reported that Innosilicon may launch the A11 series after the A10. The new Wolfshen mining machine is a customized version of AMD GPU, while the Panda mining machine is a conventional GPU mining machine.
Finally, there is the machine that assembles the graphics card, which generally uses ordinary graphics cards. Even if it is not used for mining, it can be recycled and used in other industries such as gaming, with a high residual value. Generally speaking, the residual value of a graphics card that has been mined for two years is about 30% of the market price of a new graphics card. There are also rumors of Ethereum FPGA mining machines, but there are currently no mature and cost-effective products available.
Compared with S9 or the current mainstream Bitcoin mining machine/M30S, which can have a lifespan of 3-5 years or even longer, the Ethereum mining machine is more like a short-lived game in terms of development and mining. Because if Ethereum 2.0 is upgraded in the next 2-3 years, this game will be over, but the emergence of forked chains is not ruled out.
