Calculation method and device, electronic equipment, program and medium for workload proof

Abstract

The embodiment of the present invention discloses a workload proof calculation method and device, electronic equipment, program and medium, wherein the method includes: performing multiple calculations based on the selected first random numbers respectively, and storing the calculation results in the memory respectively In order to form cache data occupying a predetermined space capacity; use the cache data and the second random number selected this time to perform hash calculation on the preset data block; determine whether the calculation result of the hash calculation meets the preset condition; if not In the preset condition, the value of the second random number is changed, and the operation of performing hash calculation on the preset data block by using the cached data and the second random number selected this time is restarted. The embodiments of the present invention greatly reduce power consumption while maintaining the advantages of fairness and robustness, and can reuse existing computing devices with a certain amount of storage space, thereby reducing the overall cost of ownership of the system .

Description

technical field [0001] The present invention relates to block chain technology, especially a calculation method and device for workload proof, electronic equipment, program and medium. 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 the current mainstream proof-of-work algorithms are all calculation-intensive algorithms based on hash collisions, which at least have the following problems: calculation-intensive algorithms need to consume a lot of power. To save electricity costs relatively, it is necessary to pay the cost in advance to p...
