Abstract:

With the continuous improvement of consumers’ requirements for the quality and safety of agricultural products, rapid response, efficient control and safety guarantee have become important topics in the field of modern agricultural products’ safety. Due to the lack of original information, the opacity of information and the poor reliability of the traditional traceability system, consumers do not trust the traceability technology of agricultural products. In addition, organizations do not trust each other, information fault often occurs, and it is difficult to trace responsibilities in face of the problems. The effect of safety control is difficult to meet social needs. Blockchain technology has the characteristics of traceability, non-tampering and decentralization, which can well offset the defects of traditional traceability system. As an emerging technology, blockchain has great potential in the traceability of agricultural products. However, the advantages, challenges and urgent problems of agricultural product traceability system based on blockchain technology have not been fully discussed. Taking rice traceability system as an example, this paper puts forward the framework design of agricultural product traceability system based on blockchain technology, and introduces how to obtain the rice supply chain data information through the Internet of Things technology in detail. Finally, the paper analyzes the advantages and challenges of the agricultural product traceability method based on blockchain technology. This paper can provide certain information on the agricultural product traceability system based on blockchain technology for researchers and practitioners and have a positive impact on improving the sustainability of agricultural products.

Key words: agricultural products, food safety, traceability, blockchain, the Internet of Things
