In recent years, the safety of agricultural products has become increasingly serious. The traditional traceability system of agricultural products is faced with the problems of lack of credibility, supervision dilemma and scalability. The traceability of agricultural product quality and safety is imminent. With the continuous development of blockchain technology, its characteristics of distributed, decentralized, non-tampering and traceability play an important role in improving the data security and transparency of agricultural product traceability system, and have received extensive attention from various industries. Based on the concept of traceability and traceability system, this paper introduces the Internet of Things and blockchain technology, and discusses some related research on the integration of blockchain and Internet of Things framework into agricultural product traceability by scholars at home and abroad. At the same time, it expounds the advantages of safety, reliability and transparency brought by the combination of Internet of Things and blockchain, and the challenges of scalability, efficiency and resource waste. Finally, it puts forward suggestions for the construction of agricultural product traceability system and future research directions.

Key words: blockchain, Internet of Things, traceability system, centralization, decentralization
