Electric power business material information storage system and method based on block chain

Abstract

The invention discloses an electric power business material information storage system and method based on a block chain. The system comprises a main chain and a slave chain which form a block chain,wherein the slave chain comprises N slave chain nodes, and the slave chain nodes are used for storing main data of power business material information; wherein the main chain comprises M main chain nodes, and the main chain nodes are used for storing associated information data of data in the slave chains. The method comprises the following steps: 1) electric power business material information isprocessed into formalized data with consistent structure and the formalized data is uploaded; 2) the slave chain of the block chain packages the associated important information and sends the packaged important information to the main chain for storage, and the whole uploading process is recorded; and 3) basic information of the power business material information is inquired through the main chain, and the main chain node can request the slave chain to inquire detailed information. Blockchain uplink storage is adopted, so that the data cannot be tampered, and the credibility is improved; bydesigning a material data model and a storage structure, data uplink information is associated, and the time cost of material data information management is reduced.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a system and method for storing power business material information based on blockchain. Background technique [0002] The storage forms of material information in the power business are different. The storage method is to put them in the corresponding data table in the form of a database. The data is loosely related and the relationship between the data cannot be directly seen. Only personnel can manage, and it is difficult to get started; and the reliability and credibility of the data cannot be guaranteed. In the prior art, for example, the patent document CN111260194A discloses a method and system for accurate material supply based on blockchain, which belongs to the field of material supply technology, including registering material supply and demand information on the chain based on blockchain technology, and the material supply and demand The information includes sup...
