Abstract: A blockchain-based energy and power data verification and traceability model is designed, which uses access control and identity authentication to store the data on the chain, and uses smart contracts to automatically authorize the data to be opened to users with specific permissions, so as to realize the information exchange between relevant participants, and make the uplink data traceable effectively. Meanwhile, the on-chain data scoring card mechanism is introduced to conduct online evaluation and supervision on the data on-chain operation of relevant personnel, solve the adverse impact of untimely archiving, and propose to add a cross-chain real-time verification method to ensure the cross-chain effective verification of the file data content on the chain, thus solving the problem of the correlation between the model mechanism of data access verification and traceability that is common in energy and power scenarios.

Key words: blockchain, electric power data, traceability verification, smart contract
