Blockchain and IoT based traceability system for agricultural products

With the arrival of digital agriculture,tens of billions agricultural IoT devices are connected to the IoT, and the accompanying problems such as data information of the whole industrial chain of products being vulnerable to tampering. In this paper, based on the problems of low efficiency and poor security of traditional traceability systems, we design an agricultural product traceability framework based on blockchain and IoT.And complete the deployment of blockchain under the open source distributed leger Hyperledger Fabric.Finally, we carry out web application development through Springboot framework to realize the agricultural product traceability system. In addition,we also conducted efficiency as well as performance analysis in the Caliper performance testing framework, and the results showed that the system improved the efficiency of agricultural product information transmission and data security, and had a significant effect on solving the problems of low efficiency and poor security of traditional traceability systems, meeting the needs of practical applications.
