Abstract:

Traceability application is an effective means to ensure the quality and safety of agricultural products that has been a public health problem of growing concern, and to ensure the authenticity and security of traceability data has become the focus and urgent problem of traceability application research. Blockchain is a complete technical solution that integrates various technologies and ensures the completeness of completely decentralized point-to-point system, with the advantages of decentralization, transparency, detrust and data unforgeability. It is not restricted by traditional centralized technology, and thus has great development space in the application of agricultural product quality and safety traceability. This paper summarized the infrastructure, key technologies and application characteristics of blockchain technology, as well as the internal relationship between blockchain technology and agricultural product quality traceability. It presented the problems existing in the research of agricultural product quality and safety traceability based on blockchain technology by analyzing the research progress and technical characteristics of agricultural product quality and safety traceability based on the public chain model, consortium chain model and improved model. Combined with the development trend of blockchain, it put forward some research prospects, such as paying attention to horizontal technology integration, strengthening the chain of detection data information, and establishing incentive and punishment mechanism for agricultural products traceability.

Key words: quality and safety of agricultural products, application of traceability, blockchain, public chain, consortium chain, data authenticity
