摘　　要：针对分布式能源交易过程中数据传输的安全问题,开展了基于分布式区块链技术的能源共享网络处理模型设计研究。在分析能源共享网络架构的基础上,构建分布式区块链平台架构,其包括基础层、区块链层、合约层、数据层与应用层共五层结构。同时基于信用评价的能源共享网络处理算法,对记账节点、验证节点及轻节点等三类节点功能特性的差异,提出了相应的信用评价方法。将信用评估结果应用于能源共享网络的处理过程中,并在传统共识算法上加以改进。通过搭建分布式区块链仿真平台进行验证分析的结果表明,所提算法能够有效抑制恶意篡改及攻击行为,以保障系统的安全性,且减少验证转发的节点数,从而提高系统验证的效率。Aiming at the security problem of distributed energy transaction data transmission,this paper carries out the design and research of energy sharing network processing model based on distributed blockchain technology.Based on the analysis of the energy sharing network architecture,a distributed blockchain platform architecture is constructed,including five layers:foundation layer,blockchain layer,contract layer,data layer and application layer.The energy sharing network processing algorithm based on credit evaluation puts forward the corresponding credit evaluation method for the differences in the functional characteristics of accounting nodes,verification nodes and light nodes.The credit evaluation results are applied to the energy sharing network processing process,and the traditional consensus algorithm is improved.A distributed blockchain simulation platform is built for verification and analysis.The results show that the proposed algorithm can effectively suppress malicious tampering and attacks,ensure system security,reduce the number of verification forwarding nodes and improve system verification efficiency.
