A Novel Blockchain-Based Model for Agricultural Product Traceability System

Abstract

At present, the application of blockchain in the traceability system has become a mainstream technology to ensure the quality and safety of agricultural products. However, blockchain is designed to ensure open and transparent data and tamper-proof, and there is a deficiency in the privacy protection of data. In this study, a novel blockchain-based model for agricultural product traceability system is proposed, which has good generality and can protect the privacy of the agricultural product information in the traceability system. First, we designed a multi-channel data collection and uploading architecture, with one channel corresponding to the collection and uploading of information of one type of agricultural product, so as to meet the actual traceability needs of various types of agricultural products. Then, the information of agricultural products uploaded by each channel is encrypted by using the hierarchical encryption algorithm, and the encrypted information is stored in the blockchain to realize the secure sharing of agricultural product information. Finally, we evaluated the system model on the Hyperledger Fabric platform.
