AbstractThe 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.
