As the basic necessity of national life, agricultural products have become the basic elements of economic and social development. Because of the complexity and uncertainty of the internal and external environment, the supply chain of agricultural products has various risks, such as vulnerability and instability in the system structure. This paper analyzes the common structural model and risk factors of agricultural product supply chain, discusses the main factors of agricultural product supply chain risk factors, and combines the characteristics of decentralization and information encryption of block chain technology with the governance of each node of agricultural product supply chain. This paper puts forward the optimal analysis of agricultural product supply chain model construction and related node risk management under block chain technology.
