The traditional trading model has some problems, such as high operating costs and the fact that trading information can be tampered with. Therefore, an electricity trading system based on Hyperledger Fabric was proposed in this paper. First, the Certificate Authority is introduced into the transaction system. By controlling the public and private keys of market entities, it is verified whether they are authorized to participate in market transactions, thereby achieving identity verification and authority control of market entities. Second, a Matchmaking Trading center is developed to match the submitted transaction information, and then a smart contract for related transactions is signed. When the transaction is completed, it is submitted to the Ordering Service for transaction sequencing, and it is recorded in Ledger after the sorting. Finally, the performance test of the power intelligent trading system was carried out. The test results show that the trading system has good applicability.
