With the emergence and widespread application of intelligent technologies such as the Internet of Things and big data, many researchers have also begun to combine emerging technologies with agricultural product traceability systems. These studies have made innovations in the platform or technology of data query and reading. However, in the traditional agricultural product traceability system, the problems of data management, such as scattered information, difficulty in sharing, and difficulty in traceability, still exist. The purpose of this article is to study the functional agricultural product safety traceability system based on blockchain technology. This article first analyzes the purpose and mode of product tracing. In view of the high cost and low tracing efficiency of traditional tracing mode, this paper improves the traditional tracing mode based on the theoretical basis of blockchain technology and proposes a reverse search and recursive algorithm a tracing scheme formed by the combination of ideas. Finally, this paper designs and implements the agricultural product safety traceability system. The experimental results show that the scheme proposed in this paper is more efficient than traditional traceability models. And by testing the performance of the system, the test results show that the system can meet the demand. In this paper, through testing the traceability rate of different schemes, the traceability rate of the scheme proposed in this paper is stable at about 1000 milliseconds.
