Design of the Core Data Traceability Method of Power Grid Based on Blockchain Technology

Because the massive power grid core data affects the efficiency of information traceability, it needs to rely on different number of traceability chains to obtain information quickly, so as to achieve better data traceability effect and improve the efficiency of power grid core data traceability. Therefore, a power grid core data traceability method based on blockchain technology is designed. Hash function is used to encrypt data. Based on blockchain technology, data blocks are filled and divided, and corresponding scheme is designed to authenticate user identity. The design strategy can update the traceability chain and update the transaction strategy block group of the access strategy. Through the combination of non-aggregation traceability and aggregation traceability, the core data of power grid is obtained, and the core data traceability model is constructed to realize the core data traceability of power grid. The experimental results show that under the condition of three chain blockchain traceability, the repeated traceability process is reduced, the core data of power grid can be obtained quickly, the effect of data traceability is ensured, and the efficiency of data traceability is improved.
