摘　　要：为适应电力市场的多样性以及电力需求的波动性,基于区块链技术提出一种分布式合同电量转让系统。将电量转让过程中所需的合同分为原始合同、电量互保协议和转让交易合同3种类型。针对每一种合同的生成,设计对应的协议。基于有序多重签名对合同的内容进行验证,确保合同的真实性,同时利用广播加密对合同内容进行保护,确保合同隐私数据的机密性与正确性。在此基础上,通过区块链存储所有合同,确保合同的不可篡改性。实验结果表明,该系统可以有效提高合同的生成与验证效率,快速达成安全的合同电量转让。This paper introduces a distributed contract-based electricity transfer system leveraging blockchain technology to adapt to the diversity of the electricity market and the volatility in electricity demand.The necessary contracts for electricity trans-fer,namely,original contracts,electricity mutual assurance agreements,and transfer transaction contracts,are categorized into three distinct types.Specific protocols are designed for the generation of each type of contract.Verification of contract authenticity is performed using ordered multi-signature schemes,ensuring the validity of the contracts.Furthermore,broadcast encryption is employed to safeguard the privacy and accuracy of contract content.All contracts are stored on the blockchain,guaranteeing their immutability.The results of experiments demonstrate that this system significantly enhances the efficiency of contract generation and verification,facilitating swift and secure electricity transfers.
