摘　　要：针对在政府采购实施过程中,很难保证程序正义、数据可靠、结果公正、监督有力、公开及时的问题,提出一种以Hyperledger Fabric为基础的政府采购信息化系统。由区块存储政府采购业务数据,提升政府采购的可信度;以通道为基础的多链设计,保护参与方的隐私或商业机密;引入监督审计节点和信息公开节点,提升监督审计的效率和质量,保证信息公开的及时性和准确性;由IPFS(Inter Planetary File System)存储非结构化数据极大减轻区块链平台的存储压力,提升系统运行效率。实验结果表明:该系统具有较好的运行效率。In order to solve the problems of procedural justice,reliable data,fair results,effective supervision and timely disclosure in the implementation of government procurement,a government procurement information system based on Hyperledger Fabric is proposed.The storage of government procurement business data by block enhanced the credibility of government procurement.The channel-based multi-chain design protected the privacy or business secrets of the participants.The introduction of supervision audit node and information disclosure node improved the efficiency and quality of supervision audit,and ensured the timeliness and accuracy of information disclosure.The storage of unstructured data by IPFS greatly reduced the storage pressure of the blockchain platform and improved the operating efficiency of the system.Experimental results show that the system has good operating efficiency.
