Abstract: Electric metering data is fundamental to power system operation and regulation. Its reliable exchange among individuals, enterprises agencies is vital for effective energy management and market transactions. However, current data-sharing models often lack trustworthiness, efficiency, and robust privacy protection, hindering cross-departmental and cross-domain data exchange within power systems. To address these issues, a blockchain-based method was developed to enhance security, real-time performance, and efficiency of electric metering data sharing. A metering chain architecture was designed, incorporating smart contracts to facilitate data transactions. Additionally, a dynamic evolutionary game-based incentive mechanism was established to promote data sharing and optimize benefit distribution. Experimental results indicate that this method effectively resists data tampering, consensus cycle, and Sybil attacks. The system achieves a throughput of approximately 20,740.37 Transactions Per Second (TPS), with a response time under one millisecond. Compared to Fabric and EEA, the data transaction rate significantly improves, ensuring efficient and secure data sharing.
