Design And Implementation Of A Blockchain-based Agricultural Product Quality And Safety Traceability Platform

With the improvement of people’s quality of life nowadays,the demand for green agricultural products continues to increase,and the quality and safety of agricultural products has also attracted the attention of the public.At present,the traditional agricultural product traceability system can help people understand the detailed information of each link in the process of agricultural product traceability.However,there are problems such as centralization of data storage,insufficient data sharing,and easy data tampering,which also cannot guarantee the correctness and authenticity of agricultural product traceability information.Blockchain is a new type of distributed storage technology,which has the characteristics of data immutability,decentralization,and data joint maintenance.These technical features can effectively solve the current traceability data problems of traditional agricultural product traceability systems.This paper uses blockchain technology to develop a set of agricultural product quality and safety traceability platforms that make information integration,circulation,and sharing in the process of agricultural product traceability more convenient and transparent.The main research contents of this paper are as follows:(1)The current situation of agricultural product traceability and the application of blockchain at home and abroad is studied,and the problems of my country’s agricultural product traceability system and the value embodied by blockchain technology are put forward.(2)The blockchain technology adopted by the agricultural product quality and safety traceability platform is analyzed,including the characteristics,basic technology and classification of the blockchain.The Hyperledger Fabric technology platform used by this platform is analyzed,and the advantages of the Hyperledger Fabric technology platform applicable to this platform are explained.(3)Designed a blockchain-based agricultural product quality and safety traceability platform.According to the needs of the platform,the physical architecture design,logical architecture design,functional module design,database design,smart contract design,transaction process design and data access layer design were carried out on the platform,and each design plan was introduced in detail.(4)A blockchain-based agricultural product quality and safety traceability platform has been realized.Deployed the web application environment and Fabric network environment of the platform,completed the realization of the main functional modules according to the designed scheme,and focused on the realization process and realization effect of the input and query of agricultural product traceability information,and the functionality of the platform The test ensures the normal operation of the platform.
