Abstract：With the development of the national economy and the growth of power demand, distributed energy has become an important part of the energy market. Blockchain technology has the advantages of decentralization, openness, transparency, and traceability, which is consistent with the non-centralized characteristics of distributed energy. Therefore, blockchain technology is suitable for solving the problem of distributed energy transaction data and trustless centers. This article selects the blockchain alliance chain in the form of a hyperledger, applies it to distributed energy transactions, and proposes a new distributed energy transaction platform by designing a transaction matching mechanism and a credit point system. Comprehensive bilateral auction mechanism and two-way matching of market supply and demand relationships, and time-stamped transaction messages are packaged on the chain for public announcement on the entire network, so that the entire transaction does not need a trust center, and runs transparently, safely and fully automatically. At the same time, the introduction of a credit points system to supervise the execution of users\' transactions is conducive to the honest transactions of platform users. According to the proposed model, a distributed energy trading platform based on blockchain is built, and the effectiveness of the platform is verified by simulation on Hyperledger Fabric.
