Embodiment Construction

[0080] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0081] Aiming at the problems in the existing voluntary computing such as low enthusiasm of volunteers, possible tampering of data, and lack of consensus, as well as the problem that the hash operation in the existing POW proof-of-work consensus mechanism greatly wastes resources, this embodiment provides A blockchain consensus incentive system based on large-scale scientific core computing, such as figure 1 As shown, the blockchain consensus incentive system includes six modules: employer module, worker module, verifier module, obfuscator module, database module and sma...

Abstract

The invention discloses a blockchain consensus excitation system and method based on large-scale scientific core computing, and the system comprises an employer which issues a computing task, designsand provides Map and Reduce program functions, task operation time limitation, a quick verification algorithm, and a reward and punishment system; workers, pledging the city security deposit and getting the calculation sub-tasks for calculation; a verifier, used for carrying out verification calculation on the sub-task calculation result according to a rapid verification algorithm; a database, used for storing the calculation task data submitted by the employer and the calculation result data provided by the worker; an obfuscator, used for covering the identity information of the employer, theworker and the verifier and randomly distributing the subtasks; and an intelligent contract, used for realizing calculation task chaining, calculation task distribution, calculation task calculationand verification, and worker reward and punishment. The blockchain consensus excitation system and method solve the problems of low enthusiasm of volunteers, possible data tampering, lack of consensusand the like.

Description

technical field [0001] The present invention relates to the combined application field of large-scale scientific computing and blockchain, in particular to a blockchain consensus incentive system and method based on large-scale scientific core computing. Background technique [0002] The emergence of computers has greatly accelerated the calculation process of scientific computing. However, after decades of development, computer technology has continued to improve, and the data scale of scientific computing has also increased dramatically. As far as the current development situation is concerned, the performance of a single computer is far from meeting the needs of existing large-scale scientific computing applications, such as: analyzing the radio signals collected by the Arecibo radio telescope to search for scientific computing applications of extraterrestrial civilizations , scientific computing applications for studying protein folding, misfolding, aggregation and relat...
