基于区块链技术改进共识机制的分布式能源交易研究

Research on Distributed Energy Trading Based on Blockchain Technology to Improve Consensus Mechanism

摘要: 对目前分布式能源交易中面临的高频率，复杂交易存在的安全性，交易成本高与交易信任难等问题，分析现有区块链技术与分布式能源交易的优缺点，提出基于区块链技术改进DPoS (Delegated Proof of Stake，委托权益证明)共识机制的分布式能源交易应用与架构。通过基于动态激励信任度的委托权益证明(DPoS)，并辅以信任度模型和奖惩机制对节点进行综合的评价。通过算例仿真分析对比，提出的改进DT-DPoS (Dynamic Trust-Delegated Proof of Stake)算法可以提高节点的积极性，增强了剔除恶意节点的效率，维护了系统的安全性与稳定性。

Abstract: With regard to the security, transaction cost, transaction trust and other problems of high frequen-cy and complex transactions in distributed energy transactions, this paper analyzes the advantages and disadvantages of existing blockchain technology in distributed energy transactions, and pro-poses a distributed energy transaction application and architecture based on blockchain technology to improve DPoS (Delegated Proof of Stack) consensus mechanism. The node is comprehensively evaluated by the DPoS based on the dynamic incentive trust degree, supplemented by the trust de-gree model and the reward and punishment mechanism. Through the analysis and comparison of simulation examples, the proposed improved DT-DPoS (Dynamic Trust Delegated Proof of Stack) algorithm can improve the enthusiasm of nodes, enhance the elimination of malicious nodes, and maintain the security and stability of the system.
