摘　　要：为完善区块链技术下水权交易平台建设,建立统一用水权交易市场,激发水权交易活跃度,结合区块链技术对水权交易机制进行重构研究。将区块链技术与水权交易目前需求进行契合分析,结合微服务技术搭建了水权交易技术框架,初步设计了基于区块链的水权交易流程与奖惩机制,并利用python语言对信用奖惩机制进行仿真。结果表明,区块链技术特征与水权交易需求高度契合,奖惩机制能够保证在不同交易情景下对参与节点进行有效奖励,并对违约节点进行信用和资金处罚,从而激励交易主体积极履行合约,提高整体交易意愿。区块链技术应用在水权全交易流程能够实现水权交易信息的完整性存储、分布式共享和追踪溯源,研究成果可以为优化水权交易机制、提高水权交易活跃度提供参考。To improve the construction of water rights trading platforms under blockchain technology,establish a unified water rights trading market,stimulate the activity of water rights trading.Subsequently,we combined blockchain technology to reconstruct the water rights trading mechanism.We analyzed the compatibility between blockchain technology and the current demand for water rights trading,and combined it with microservices technology to build a water rights trading technology framework.We initially designed a blockchain based water rights trading process and reward and punishment mechanism,and simulated the credit reward and punishment mechanism using Python.The results indicate that the characteristics of blockchain technology are highly compatible with the needs of water rights trading,and the reward and punishment mechanism can ensure effective rewards for participating nodes in different trading scenarios,as well as credit and financial penalties for defaulting nodes,thereby motivating trading entities to actively fulfill contracts and improving overall trading willingness.The application of blockchain technology in the entire water rights trading process can achieve complete storage,distributed sharing,and traceability of water rights trading information.The research results can provide reference for optimizing water rights trading mechanisms and improving water rights trading activity.
