The traditional agricultural product supply chain traceability system suffers from issues such as the lack of coordination between on-chain and off-chain data, the mismatch of consensus mechanisms and the poor security of traceability data. These problems fail to meet the overall traceability requirements of the agricultural product supply chain and pose higher demands on traceability schemes and technologies. Therefore, based on the current research on blockchain in agricultural supply chain traceability, it aims to establish an agricultural supply chain traceability system with the physical layer, core layer, data layer, and application layer as the overall framework by leveraging blockchain technology and integrating the hierarchy and operation process of the agricultural supply chain. It focuses on enhancing the overall efficiency of blockchain traceability, constructing the blockchain security guarantee system, and improving the blockchain privacy protection technology. Through the above research, the technical innovation direction is offered for China’s agricultural product supply chain traceability, the continuous maturation of blockchain technology and its application are promoted, and innovative thoughts are provided for improving the coordinated development level of China’s agricultural product supply chain, the efficiency of agricultural product quality and safety management, and the quality of agricultural product supply chain traceability.
