The Blockscale chips were SHA-256 hardware accelerators designed for proof-of-work calculations. [4] According to Intel, they were capable of up to 580 GH/s with a power consumption of up to 22.7 W, and a claimed efficiency of up to 26 J/TH. [5] The product came in three variants: the Blockscale 1120, 1140, and 1160. [3]
Like SHA-2, BLAKE comes in two variants: one that uses 32-bit words, used for computing hashes up to 256 bits long, and one that uses 64-bit words, used for computing hashes up to 512 bits long. The core block transformation combines 16 words of input with 16 working variables, but only 8 words (256 or 512 bits) are preserved between blocks.

It was designed such that parallel implementations are bottle-necked by memory bandwidth in an attempt to worsen the cost-performance trade-offs of designing custom ASIC implementations. ASIC resistance in Equihash is based on the assumption that commercially-sold hardware already has quite high memory bandwidth, so improvements made by custom ...

For miners, however, an ASIC rig offers greater efficiency and speed than a traditional GPU, which manufacturers argue will enable miners to unlock more value. Who is correct in the long term ...
The rise of cryptocurrency has created a demand for ASIC-based mining machines. Although most cryptocurrencies use the SHA-256 hash function, the same ASIC technology could be used to create hashcash solvers that are three orders of magnitude faster than a consumer CPU, reducing the computational hurdle for spammers.
A diagram of a bitcoin transfer. The bitcoin protocol is the set of rules that govern the functioning of bitcoin.Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all bitcoin transactions; mining and proof of work, the process to create new bitcoins and verify transactions; and ...
