Abstract: 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.
