Embodiment Construction

[0052] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0053] The blockchain system has the characteristics of decentralization. It is different from the traditional centralized server. Since the blockchain system does not have a centralized node, it needs a consensus mechanism to maintain normal operation. For example, the consensus mechanism includes the POW algorithm, based on the POW algorithm, block The chain system can realize block consensus verification.

[0054] The POW algorithm is a strategy to deal with denial of service attacks and other service abuses. A proof-of-work refers to a data calculation that meets specific conditions. It is ...

Abstract

The invention relates to the technical field of block chains, in particular to a consensus verification method based on block chains, a mining machine and a block chain system. The method comprises the following steps of: sending a mining task request to each miner node, wherein the mining task request carries a search number, and the search number being obtained by performing a modulo operation of N on a known constant M; the hash value to be verified corresponding to the search number uploaded by each miner node being received, and the known constant M being obtained by hashing the combinedblock information, which is composed of the block information recorded by the block head in the current block, the block height information of the current block and the mining start time; validating the current block based on the hash value to be validated. Because the hash values corresponding to the same search number are different, the proxy node can avoid repeating the same verification work,thereby saving energy consumption relatively.

Description

Technical field [0001] The present invention relates to the technical field of block chains, in particular to a consensus verification method based on block chains, mining machines and block chain systems. Background technique [0002] Some blockchain systems support a proof of work mechanism ((Proof of Work, POW). According to the proof of work mechanism, each miner node independently completes the proof of work calculation. When a random number that meets the preset conditions is found, the package record is obtained. The right to account. [0003] In the process of implementing the present invention, the inventor found that the traditional technology has at least the following problems: Since each miner node independently completes the proof of workload, it is easy for each miner node to repeatedly calculate the same workload, thereby causing energy waste. Summary of the invention [0004] One objective of the embodiments of the present invention is to provide a consensus verifi...
