A TRUSTED BLOCKCHAIN-BASED TRACEABILITY SYSTEM FOR FRUIT AND VEGETABLE AGRICULTURAL PRODUCTS

Abstract

The traditional method of traceability suffers from the issues of centralised administration, opaque information, questionable data, and the simple creation of information islands. This article develops a traceability system based on block chain technology for the storing and querying of product information in order to tackle the difficulties that have been outlined above in the chain of distribution of agricultural goods. Taking use of the traits of decentralisation, tamper-proofing, and because block chain technology enables traceability, there has been an improvement in both the transparency and reliability of traceability information. A dual storage system consisting of both on-chain and off-chain traceable information, referred to as "database plus blockchain"is built to alleviate load strain on the chain and achieve effective information querying via its construction. Blockchain,it has been suggested that technology paired with encryption may be used to enable the secure exchange of confidential information in the network built on the blockchain In addition to this, we provide a reputation-based smart contract as an incentive for network nodes to participate. Upload traceability data. In addition to this, we provide performance analysis as well as practical application, the outcomes of whichdemonstrating that our method increases both the effectiveness of queries and the safety of confidential information, as well as ensuring that ensuring the validity and reliability of data in supply chain management, as well as ensuring that it complies with real application needs.
