China's Bitmain is one of the market segments in the mining machine market, bringing 80% to 90% market share to the world's miners and net profit of 30 million U.S. dollars per month In addition, by virtue of its large demand market of mining machines, it designs its own dedicated ASIC chips such as Bitcoins and Litecoin, making the mainland of China bit like the top 5 of China's IC design companies and contributing to TSMC's near 10 % Of total revenue.
Bitmain S9, designed by Bit Continental, is the main model currently being designed specifically for Bitcoin mining but due to the hash algorithm used in Bitcoin, which is based on the SHA-256 algorithm , Not only consumes computing power but also consumes energy. In the future, as the number of Pittcoin becomes scarcer and the rate of mining success becomes more and more difficult, the Berthe continent develops ethereums for the future demand.
It is understood that the ethernet ETHASH algorithm used, originally designed for the memory of the band width (band width), which is the demand for graphics chips from. Therefore it is suitable for PC mining, mining machine is not good at this However, because Ether is likely to adopt PoS proof of stack mode after mid-2019, which will make the current mining machine more difficult to enforce, the continent designed the new mining machine , To meet the market demand later.
According to "Science and Technology News" exclusive grasp of the news, bit mainland China is about to launch mining models for the etheric ether F3, the design is to increase the DRAM bus bandwidth, but also to increase the size of the memory. In the future, each dig Each of the miner's has three motherboards, each with six ASIC processors dedicated to mining, and each ASIC dedicated to mining has a 32-bit 1Gb DDR3 memory. In total, a F3 dig There will be 72 GigaByte of DRAM memory on the miner, which will vary widely in memory size compared to the current S9 miner with bitcoin only 512MB of DDR3 memory.
Market estimates, because the F3 energy consumption is small, the benefits of large, the future in the future after the official launch, will impact the original graphics chip PC mining market.Because of optimistic about such a market, the recent frequent bit mainland China to Taiwan meeting memory plant , To discuss whether it can provide the relevant memory capacity.It is understood that this part of the bit mainland demand is about 3 thousand 12-inch wafers per month, this part of the current domestic memory plant are still trying to squeeze out the production capacity supply. As for the TSMC chipmaker that will be handed over to TSMC's foundry 28nm process, it will be mass-produced and shipped in February, while the bitcoin-based mining machine in the mainland of the continent is expected to ask Q2 and Q3 of 2018 .
