This paper proposes a distributed power transaction intelligent matching system based on blockchain technology. By building a decentralized trading platform

it realizes point-to-point autonomous transactions between power supply parties and electricity purchasing parties. The system integrates smart contracts

distributed identity authentication

encrypted transmission and aggregate signature mechanisms to ensure the security and traceability of transaction data

while reducing trust costs and transaction disputes. The research has verified the technical feasibility of blockchain in distributed energy transactions

and provides a new type of infrastructure support for the transformation of the energy Internet.
