Led by the strategic goals of “carbon neutrality” and “carbon peaking”，the development of distributed energy has become one of the main paths for China’s energy structure optimization and power market reform. The decentralized idea of blockchain is in line with the idea of distributed energy construction，which can provide reference for the development of distributed energy industry. Firstly，this paper fully explores the basic principles of blockchain and distributed energy，and explains the significant advantages of blockchain-based distributed energy system in terms of data security，trust mechanism and operation efficiency. Secondly，according to the five main application scenarios of energy blockchain，the application mode and positive effects of blockchain technology in distributed energy industry are sorted out. Next，the challenges faced by blockchain technology in distributed energy applications are described，and the key scientific issues that need to be solved are analyzed. Finally，the development vision of distributed energy blockchain is foreseen，and specific suggestions are made in terms of industrial integration，policy system，technology reserve and talent training.
