China’s Bitcoin mining large Bitmain is engaged on an Ethereum ASIC miner, the Antminer F3, in line with reports in Chinese technology media.
The report states that the Antminer F3 will probably be mounted with three motherboards with six ASICs per motherboard, in addition to 32 x 1GB DDR3 reminiscence chips.
Apparently the brand new ETH ASIC chips will start manufacturing later this month, with the ASICs hitting 200-200MH/s. The price of every Antminer F3 will probably be between $2500 and $3000. The F3 miner is predicted to hit the market in Q2 or Q3 2018, mentioned reviews.
72 GB DRAM outperforms many of the GPU-based mining rigs out there now. Mining specialists say Bitmain’s demand for DRAM reminiscence is round three,000 items of 12 inch wafers per 30 days.
Bitcoin mining migrated from CPUs to GPU’s to FPGAs and now to ASICs. Nevertheless, Ethereum is putatively ASIC-resistant; its ethash proof of labor (PoW) mining algorithm is “reminiscence exhausting” or reminiscence certain.
With out going into an inappropriate stage of element, which means that calculating the PoW requires selecting subsets of a hard and fast useful resource depending on the nonce and block header. This useful resource (a number of gigabyte measurement knowledge) is a pseudorandom dataset known as a DAG (Direct Acyclic Graph), which is regenerated each 30,000 blocks, or about each 5 days.
Vijay Pradeep, a Silicon Valley robotics engineer and angel investor, who’s thinking about reminiscence hardness, mentioned: “Observe that this Bitmain ASIC has a bunch of DDR controllers, connecting it to an enormous financial institution of DRAM. So, architecturally, this appears vastly completely different than the Bitcoin miners in the marketplace at present.”
Predeep has posted about methods to customise Ethereum mining , specifically how to design a high memory bandwidth FPGA/ASIC board.
Bitmain lately introduced an ASIC miner for decentralised storage blockchain token Siacoin. This brought on some dismay for Sia which was planning its personal ASIC “Obelisk” items. Sia Founder David Vorick stated that the Bitmain unit is far less energy efficient, prices more cash, and is an objectively worse miner than the SC1. So individuals who ordered Obelisk items will nonetheless be receiving of considerable worth”.
Vorick was one of many few individuals who mentioned ASIC mining on Ethereum was prone to occur and that the R&D was most likely underway.
Again in January, Vorick mentioned in an e mail to IBT: “We had our chip devs look into each ethash and Equihash, and we really feel that each could be pretty straightforward to make ASICs for. For equihash you simply make a sorting community in , and for ethash you make an enormous lookup pipeline.”
This story has quite a few fascinating permutations. It means that unsentimental profit-seeking miners think about Ethereum’s shift to proof of stake to be suitably distant to advantage creating an ASIC miner.
It is also fascinating by way of what it means for the likes of NVIDIA and AMD. It must be famous that GPU chip makers are skittish about speaking publicly about how a lot they’re making from cryptocurrency mining; they may usually say they do not know what number of of their GPUs are offered for mining (each time multiple GPU is offered at a time could be an indictor).
One other one that is thinking about mining and doubted Ethereum’s ASIC-resistance is Bram Cohen, the inventor of BitTorrent and founding father of Chia Community.
He mentioned in an e mail: “ASIC resistance is not usually such a scorching concept. By making an attempt to make it value prohibitive to make ASICs, you may possible (maybe inevitably) fail and wind up with it merely being very costly, which can end in little or no if any competitors amongst ASIC producers.
“A greater strategy is to attempt to be ASIC commodity, the place a comparatively modest funds can produce about nearly as good of an ASIC as can probably be made. In all probability one of the best algorithm for that’s SHA3 iterated 100 occasions.
“SHA3 is especially properly suited to easy implementation, and iterating 100 occasions removes many of the methods which could be performed to basically make awful chips which regularly fail however eat sufficient much less energy that the failure price is value it.”
Bitmain says on the requests part of its web site that response time will probably be impacted by Chinese language holidays.
