Problems solved by technology

[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 purchase special equipment with low power consumption, which increases the overall cost of the system

Abstract

The embodiment of the invention discloses a proof-of-work calculating method and device, electronic equipment, a program and a medium. The method comprises the following steps: calculating for multiple times based on a selected first random number respectively, and respectively storing calculation results into a memory, so as to form caching data occupying predetermined space capacity; carrying out Hash calculation on a preset data block by utilizing the caching data and a second random number selected at the present time; judging whether a calculation result of the Hash calculation meets preset conditions; and if the calculation result does not meet the preset conditions, changing a value of the second random number, and restarting to execute an operation of carrying out the Hash calculation on the preset data block by utilizing the caching data and the second random number selected at the present time. The embodiment of the invention has the advantages that electric power consumptionis greatly lowered while the advantages of fairness and robustness are maintained, and existing computing equipment with a certain memory space can be reused, so that total ownership cost of a systemis reduced.

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...
