Electric power data storage and query method and system based on block chain technology

Abstract

The invention provides a power data storage and query method and system based on a block chain technology, and relates to the field of block chains. The electric power data storage and query method based on the block chain technology comprises the following steps: classifying electric power data, designing block chains with different functions, and storing the data into different block chains according to the classification; in the power block chain, using an elliptic curve digital signature algorithm and asymmetric cryptography to carry out system initialization, and generating a key; and enabling the block chain smart contract to complete identity authentication through the key and store the data in the block. according to the method and system, only the corresponding account number can be added to the block chain network by setting the authority of the role of the block chain account number, and the identity is subjected to secondary verification, so that the privacy protection of the block chain data is realized, and the security of the block chain system is ensured. In addition, the invention further provides an electric power data storage and query system based on the block chain technology. The system comprises a classification module, an encryption module and a storage module.

Description

technical field [0001] The present invention relates to the field of blockchain, in particular, to a method and system for storing and querying power data based on blockchain technology. Background technique [0002] On the whole, the combination of blockchain and the Internet of Things is still in a development stage. Up to now, no super application has appeared. The blockchain uses a consensus algorithm to achieve consensus among distributed nodes and build trust. Although there are a variety of consensus algorithms to choose from, it is difficult to balance performance and security requirements. For specific application scenarios, it is necessary to select an appropriate consensus algorithm. For example, for high-frequency small transactions, you can add a side chain on the basis of the main chain combined with the design of a certain credit mechanism, and regularly synchronize data with the main chain to ensure fast transactions. Complete; for data sharing in a relative...

Problems solved by technology

[0003] Due to the characteristics of the distributed intelligent power energy system, many problems have also made its development encounter difficulties. First, there are many types of distributed power generation sources, different power generation capabilities, large quantities, and scattered geographical distribution, so that manual management, Scheduling and maintenance are very difficult. In addition, the power generation of new energy sources such as wind and light depends entirely on natural conditions, which cannot be accurately predicted and is unstable. Coupled with equipment investment and maintenance costs, their profits are low or even impossible to guarantee. These two major However, the establishment of the system is only the initial problem. If such a system can be successfully established and connected to the power grid, the operation of the system will be another matter. big problem

[0004] Generally speaking, blockchain electronic data storage will face the following problems: (1) the degree of automation in the process of depositing certificates is not high; (2) the risk of electronic data depositing certificates in the process of depositing certificates is relatively high; The legal process is cumbersome; (4) lack of electronic data security; (5) lack of mutual trust
