中文摘要: 在现代化的电力行业中,每年都需要采购大量的电力设备用于建设电网工程,由于电网建设环节复杂、所需物资设备类型较多,很难管理和众多供应商签订的物资合同.为了提高合同签订效率、保障电网建设工程的进度和质量,文章提出了把区块链技术应用在电力行业物资合同的管理中,由电网企业和设备供应商之间建立的用于签订合同的联盟链,并提出了一种基于改进的委托权益证明(DPoS)的实用拜占庭容错(PBFT)的共识机制,该机制结合合同签订次数给节点动态授权,优化了代理节点的选择策略.以区块链技术实现的电子合同既有传统电子合同建立在密码学算法基础上的安全性,又有多方协作、不可篡改和可追溯的透明性和真实性,使物资合同的签订和后续的管理都更加便捷和安全.
Abstract:In the modern power industry, a large amount of power equipment needs to be purchased every year for the construction of power grid projects. Due to the complicated construction of the power grid and the large number of materials and equipment required, it is difficult to manage the material contracts signed by many suppliers. Signing the efficiency and ensuring the progress and quality of the power grid construction project, the article puts forward the application of the blockchain technology in the management of the power industry material contract, the alliance chain established between the grid enterprise and the equipment supplier for signing the contract, and A practical Byzantine Fault Tolerance (PBFT) consensus mechanism based on improved Debt Proof of Entitlement (DPoS) is proposed. This mechanism combines the number of contract awards to dynamically authorize nodes and optimizes the selection strategy of proxy nodes. The electronic contract realized by blockchain technology not only has the security of traditional electronic contracts based on cryptographic algorithms, but also has multi-party cooperation, non-tampering and traceability of transparency and authenticity, so that the signing and follow-up of material contracts Management is more convenient and safe.
