Analysis of Agricultural Products Supply Chain Traceability System Based on Internet of Things and Blockchain

The quality and safety of agricultural products cannot be separated from rural revitalization. This is also related to the interests and development of participating in the agricultural supply chain. The traditional unitary agricultural product quality supervision system meets the growing market demand and requirements. This paper constructs the traceability and blockchain of agricultural products supply chain, as well as the trusted computing model of Internet of things nodes based on blockchain. The results show that the trusted computing model of IOT nodes based on blockchain can effectively identify and remove malicious nodes, ensure the effectiveness, tamperability, security, and reliability of agricultural product process data, greatly reduce the transaction delay, and provide a guarantee.
