Blockchain-based data comparison and consensus method

Abstract

The invention discloses a data comparison and consensus method based on a block chain, which comprises the following steps: analyzing the data to be stored in a server to obtain a storage number corresponding to the data; obtaining a first consensus number corresponding to the first data when data consensus is carried out in the block chain, obtaining a first storage number corresponding to the first consensus number in the block chain database based on the first consensus number, and obtaining consensus data corresponding to the first data based on the first storage number; when comparing data in a block chain, analyzing the second data and the third data to be compared in the server, obtaining a first comparison number corresponding to the second data, obtaining a second comparison number corresponding to the third data, comparing the first comparison number with the second comparison number, obtaining similarity information of the two numbers, and obtaining a comparison result of the second data and the third data based on the similarity information of the two numbers, thereby achieving a technical effect of high data comparison and consensus efficiency and accuracy.

Description

technical field

[0001] The present invention relates to the field of big data analysis, in particular to a blockchain-based data comparison and consensus method. Background technique

[0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system.

[0003] Blockchain (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks associated with each other using cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
