Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found through research that if the first random number (nonce1) is pre-selected and immutable in the proof-of-work mechanism, it is possible that in a certain round of proof-of-work, all All participants in the system (i.e. mining machines) cannot find a suitable second random number (nonce2), resulting in the fact that this round of proof of work cannot be completed no matter how long it takes

Abstract

The invention discloses a proof-of-work calculating method and system, electronic equipment, a program and a medium. The method comprises that a proof-of-work parameter is updated according to a preset period, the updated proof-of-work parameter is published, so that a mining machine calculates the proof-of-work on the basis of the updated proof-of-work parameter; and after that a proof-of-work result reported by the mining machine is received, whether the mining machine reporting the proof-of-work result completes the proof-of-work is confirmed according to whether the proof-of-work result iscompleted on the basis of the published proof-of-work parameter. Thus, a dead locking condition, namely, the condition that there is no participant that can complete the proof-of work, can be avoided.

Description

technical field [0001] The present invention relates to virtual digital currency technology, especially a calculation method and system, electronic equipment, program and medium for proof of work. Background technique [0002] In an open large-scale distributed system, Proof-of-work is an important mechanism to solve the Byzantine general problem and achieve system consistency. It requires participants to pay a certain amount of computing resources to prove that they have no malicious attacks on the system. The workload proof mechanism has the advantages of fairness and robustness. [0003] In the process of realizing the present invention, the inventor found through research that if the first random number (nonce1) is pre-selected and immutable in the proof-of-work mechanism, it is possible that in a certain round of proof-of-work, all All participants in the system (namely: mining machines) cannot find a suitable second random number (nonce2), which leads to the fact tha...
