Discussion on cooperative governance and security storage technology of power data based on blockchain

Abstract

The power grid business has the characteristics of wide coverage, diverse terminal equipment types, large numbers, and rich business scenarios. The blockchain technology itself has the characteristics of non-tampering and traceability, which is highly compatible with the opening of the power grid business and can be powerful supporting the digital transformation strategy of the power grid company. In order to ensure the authenticity and reliability of electric power data, data security and reliable storage technology was studied based on blockchain technology. On the data source side of the power system, a set of oracles mechanism for the grid data on-chain process was designed to achieve data reliability and consistent transmission. In addition, to prevent data damage or malicious tampering after power grid data on the blockchain, a hybrid data storage scheme based on shadow chain was proposed to realize data safe storage and improve value-added services such as data storage and sharing.
