In cryptography, a custom hardware attack uses specifically designed application-specific integrated circuits (ASIC) to decipher encrypted messages. Mounting a cryptographic brute force attack requires a large number of similar computations: typically trying one key , checking if the resulting decryption gives a meaningful answer, and then ...
Bitmain's first product was the Antminer S1 which is an ASIC bitcoin miner making 180 gigahashes per second (GH/s) while using 80–200 watts of power. [8] Bitmain as of 2018 had 11 mining farms operating in China. [7] Bitmain was involved in the 2018 Bitcoin Cash split, siding with Bitcoin Cash ABC alongside Roger Ver. [9]
Structured ASIC design (also referred to as "platform ASIC design") is a relatively new trend in the semiconductor industry, resulting in some variation in its definition.
