Abstract

The invention discloses an optimizing method, device and circuit for Hash computing chip of bitcoin proof of work, and relates to the technical field of cipher computing, computer network and integrated circuits. The optimizing method comprises that a second input of the Hash computing chip is kept constant periodically, and when the second input is constant, a computing circuit corresponding to the second input is switched off; an initial first input of the Hash computing chip is changed, and a corresponding new first input is obtained; and Hash computing is carried out on each first input, the corresponding second input and a random number to search proof of work that satisfies the requirement, and each first input comprise the initial first input and the new first input. The method, device and circuit provided by the invention greatly reduce the power consumption of the circuit.

Description

Technical field [0001] The invention relates to the technical fields of cryptographic calculations, computer networks and integrated circuits, in particular to a method, device and circuit for optimizing a hash calculation chip for proof of Bitcoin workload. Background technique [0002] The calculation method of digital encryption currency Bitcoin mining see figure 1 , By exhaustively enumerating the random value 1nonce1, the random value 2nonce2, and the random value nonce to make the final result of a series of hash operations less than the value corresponding to the current difficulty of the operation, a Bitcoin block that meets the protocol is successfully found. After the transaction hash merkle_hash is obtained from the random value 1nocne1, the random value 2nonce2 and the related data through the relevant hash operation in accordance with the protocol, the transaction hash merkle_hash is high 32bit and 32bitnonce, and the 32bit variable network difficulty is nbit, time nt...
