Research On Traceability Application Of Agricultural Products Based On Blockchain ——Taking Jingdong Chestnut Traceability System As An Example

Agricultural products are one of the important sources of human food.The wide variety of agricultural products and complex supply chain lead to the uneven quality of agricultural products purchased by consumers.Traceability of agricultural products is an important reference for consumers to judge the quality of agricultural products before purchase.Under the background of rural revitalization,the supply chain of agricultural products continues to upgrade,and it is of great significance to establish a credible traceability system of agricultural products.Through the research on the traceability of agricultural products,according to the characteristics of the supply chain of agricultural products and combined with the blockchain technology,this thesis designs and implements the traceability system of agricultural products.Firstly,this thesis discusses the traceability background of agricultural products and the fundamental significance of agricultural product traceability,analyzes the existing agricultural product traceability system and the application of blockchain technology at home and abroad,and makes it clear that the core content of this thesis is to apply blockchain technology to the field of agricultural product traceability to ensure the authenticity and credibility of agricultural product traceability information.Secondly,according to the characteristics of agricultural products supply chain,select the mature blockchain underlying framework with open source projects and rich Platform SDK interfaces to design and analyze the traceability scheme of agricultural products.Finally,taking Jingdong chestnut as the research object,the related functions of agricultural product traceability system are designed and realized.Take Ethereum private chain as the underlying framework of the system,store information,and complete transaction logic in the form of smart contract.Ensure that when consumers trace the source of agricultural products,the agricultural product information queried is not tampered with and reliable.This design can realize the purpose of storing agricultural product supply chain data.It is a measure to avoid the problems of data opacity,easy tampering and information centralization in the traditional agricultural product traceability system,and can promote the upgrading of agricultural product industry chain.This design can achieve the purpose of recording the data of agricultural products supply chain and the source of agricultural products,solve the problems of data opacity,easy tampering and information centralization in the traditional agricultural products traceability system,and promote the upgrading of agricultural products industrial chain.
