As a decentralized distributed accounting model

blockchain can implement peer-to-peer transactions that require no trust or decentralization between nodes through data encryption

timestamp and smart contract. The rational use of the relevant characteristics of blockchain can provide effective technical support for market-based transactions of distributed generation.First of all

based on the basic concepts of blockchain

the contrast relationship between blockchain and market-based transaction of distributed generation is analyzed.The differences and similarities between blockchain in less-centralized management and decentralized management are analyzed in the aspects of key links of market-based transaction of distributed generation

such as market access

transaction mode

member game

security check

congestion management and transaction settlement. Finally

the urgent problems to be solved in the application of blockchain in market-based transaction of distributed generation are analyzed

and the future research directions are put forward.
