Application of Blockchain Technology in Agricultural Product Traceability System

摘要

Agricultural products are the foundation of the people's survival, and the quality of agricultural products has always been the focus of attention of society and the government; the original agricultural product traceability system is too difficult to tamper with data due to the excessive concentration of data storage, it faces the challenge of fraudulent data tracing, and it is difficult for consumers to trust such traceability results. Moreover, the centralized storage method is not conducive to the centralized management of traceable data from many enterprises, and there will be problems of low traceability and difficulty in government supervision. The emergence of blockchain technology provides a new solution for data security problems of food traceability, its decentralization, anti-tampering and other characteristics and data encryption technology improve the difficulty of data fraud and ensure data security. If the blockchain is combined with the traceability of agricultural products, the safety of traceable data and the tampering of data can be guaranteed to the greatest extent, the producer's production behavior can be regulated, and consumers' confidence in food quality can be improved. This paper mainly proposes a framework of agricultural product traceability system based on Hyperledger technology, it uses blockchain to store the traceability data of agricultural products safely, and proposes a traceability model of agricultural products, which can cover the entire industrial chain of agricultural products, and consumers can query the authentic source of traceability of agricultural products [1].
