In order to improve the operational efficiency of retail market and reduce the security risk in transaction processes

this paper presents a framework of smart distribution trading platform based on blockchain technology. An all-parameter competitive transaction mechanism in distribution network has been designed based on double auction mechanism to improve P2P(peer-to-peer)matchmaking efficiency and restrain prosumer's market behavior. This paper designs the hierarchical framework of smart distribution trading platform for real-time transaction request and data acquisition which enables data security interaction between highly coupled energy flow and information flow using Ethereum blockchain technology. Case studies show the operational efficiency

information traceability and transaction instantaneity of smart distribution trading platform.
