Bitmain out the bushes with ASIC Ethereum miner

Bitmain is working on an Ethereum ASIC miner, the Antminer F3, according to reports te Chinese technology media.

China’s Bitcoin mining giant Bitmain is working on an Ethereum ASIC miner, the Antminer F3, according to reports ter Chinese technology media.

The report states that the Antminer F3 will be mounted with three motherboards with six ASICs vanaf motherboard, spil well spil 32 x 1GB DDR3 memory chips.

Evidently the fresh ETH ASIC chips will start production zometeen this month, with the ASICs hitting 200-200MH/s. The cost of each Antminer F3 will be inbetween $2500 and $3000. The F3 miner is expected to klapper the market ter Q2 or Q3 2018, said reports.

72 GB DRAM outperforms most of the GPU-based mining equipments te the market now. Mining specialists say Bitmain’s request for DRAM memory is around Three,000 chunks of 12 inch wafers vanaf month.

Bitcoin mining migrated from CPUs to GPU’s to FPGAs and now to ASICs. However, Ethereum is putatively ASIC-resistant, its ethash proof of work (PoW) mining algorithm is “memory hard” or memory tied.

Without going into an inappropriate level of detail, this means that calculating the PoW requires choosing subsets of a immobilized resource dependent on the nonce and block header. This resource (a few gigabyte size gegevens) is a pseudorandom dataset called a DAG (Onmiddellijk Acyclic Graph), which is regenerated every 30,000 blocks, or about every five days.

Vijay Pradeep, a Silicon Valley robotics engineer and gifangel investor, who is interested te memory firmness, said: “Note that this Bitmain ASIC has a bunch of DDR controllers, connecting it to a ample canap of DRAM. So, architecturally, this looks vastly different than the Bitcoin miners on the market today.”

He added: “The Bitmain treatment is not a magic bullet for mining. With bitcoin mining, moving from GPU to ASIC talent an order-of-magnitude increase ter efficiency (both te energy and hw cost). The Bitmain system will help ease a worldwide shortage on GPUs and increase Ethereum mining efficiency, but surely not by an order of magnitude.

“Bitmain is building custom-made hardware for a cryptocurrency that claims to be transitioning to proof-of-stake. There is lots of contention around the schedule and treatment for transitioning to proof-of-stake, and with Bitmain making massive investments into Ethereum proof-of-work custom-built mining equipment, wij now have another player who will actively lounge against Proof-of-Stake for Ethereum.”

Bitmain recently announced an ASIC miner for decentralised storage blockchain token Siacoin. This caused some dismay for Sia which wasgoed programma its own ASIC “Obelisk” units. Sia Founder David Vorick stated that the Bitmain unit is far less energy efficient, costs more money, and is an objectively worse miner than the SC1. So people who ordered Obelisk units will still be receiving hardware of substantial value”.

Vorick wasgoed one of the few people who said ASIC mining on Ethereum wasgoed likely to toebijten and that the R&D wasgoed very likely underway.

Back te January, Vorick said te an email to IBT: “Wij had our chip devs look into both ethash and Equihash, and wij feel that both would be fairly effortless to make ASICs for. For equihash you just make a sorting network ter hardware, and for ethash you make a giant lookup pipeline.”

This story has a number of interesting permutations. It suggests that unsentimental profit-seeking miners consider Ethereum’s shift to proof of stake to be suitably distant to merit creating an ASIC miner.

It’s also interesting ter terms of what it means for GPU mining ter general, not to mention the likes of NVIDIA and AMD. It should be noted that GPU chip makers are skittish about talking publicly about how much they are making from cryptocurrency mining, they will typically say they don’t know how many of their GPUs are sold for mining (whenever more than one GPU is sold at a time would be an indictor).

Another person who is interested te mining hardware and doubted Ethereum’s ASIC-resistance is Bram Cohen, the inventor of BitTorrent and founder of Chia Network.

He said ter an email: “ASIC resistance isn’t generally such a hot idea. By attempting to make it cost prohibitive to make ASICs, you’ll likely (perhaps inevitably) fail and wind up with it merely being very expensive, which will result ter very little if any competition among ASIC manufacturers.

“A better treatment is to attempt to be ASIC commodity, where a relatively modest budget can produce about spil good of an ASIC spil can possibly be made. Very likely the best algorithm for that is SHA3 iterated a hundred times.

“SHA3 is particularly well suited to straightforward hardware implementation, and iterating a hundred times gets rid of most of the tricks which can be played to essentially make lousy chips which often fail but consume enough less power that the failure rate is worth it.”

Bitmain says on the requests section of its webstek that response time will be impacted by Chinese holidays.
