Abstract: In order to improve the shortcomings of the traceability system of agricultural products and improve the quality of agricultural products, based on the pilot application of new blockchain technology, this paper analyzed the necessity of applying blockchain technology to agricultural product traceability by studying blockchain technology, and expounded and analyzed the application technology route of blockchain technology in agricultural product traceability system. The analysis showed that the combination of blockchain technology and agricultural product traceability can effectively improve the deficiencies of traceability system. The research results could be applied in similar product traceability systems and provide support for ensuring product quality.
