摘要
Aiming to solve the problems of centralized data storage, easy data tampering, and data trust in the existing agricultural product quality traceability system, as well as to ensure the quality and safety of agricultural products, protect the rights and interests of consumers and improve the brand competitiveness of production enterprises. Based on the analysis of the agricultural product industry chain business process and the key technologies of the blockchain, the trusted traceability block structure of agricultural products was designed to ensure that the traceability data of agricultural products were unforgeable, safe and reliable; the "On-Chain+Off-Chain" agricultural product was proposed. The collaborative management and storage strategy of quality and safe traceability information solved the problems of high data storage pressure, low query efficiency and data explosion of each node in the agricultural product traceability blockchain network. Kafka consensus mechanism was used to achieve consensus operations with multi-agent participation and provide real time data with high throughput, high-volume and low-latency processing capabilities; and agricultural product traceability smart contract rule sets and contract trigger conditions were developed to ensure the reliability of agricultural product data and the credibility of the traceability platform. A trusted traceability system was developed for agricultural product quality and safety based on the Hyperledger Fabric blockchain platform, and the verification and analysis were conducted on the traceability of the quality and safety of black tea products. The results showed that the developed agricultural product quality and safety credible traceability system can solve the problems of data security and authenticity of traceability information among multiple nodes in the production, processing and circulation of the agricultural product industry chain, which achieved good application results. © 2022, Chinese Society of Agricultural Machinery.
