Research And Implementation Of Anti Tampering For Edible Agricultural Products Traceability Information Base On Blockchain Technology

The quality and safety of edible agricultural products is one of the most concerned issues of the government and consumers.Traditional traceability system of edible agricultural products has some problems,such as centralized information storage,low cost of counterfeiting,low efficiency of multi-point production records reconciliation,so it is still very urgent to find a more efficient and perfect traceability method.With the promotion of the implementation of blockchain technology and the need for traceability of edible agricultural products,the government is eager to ensure the authenticity of traceability information of edible agricultural products through the application of blockchain technology in the construction of traceability system of edible agricultural products.Therefore,it is of great significance and application value to develop a traceability system of edible agricultural products based on blockchain.The main research contents and achievements are as follows.(1)This thesis analyzes the importance and urgency of anti tampering of traceability information of edible agricultural products.The importance and urgency of developing traceability system of edible agricultural products based on blockchain technology are analyzed and expounded from the perspective of background of topic selection,safety of edible agricultural products,technology realization and application,as well as the demand of existing wholesale market.(2)Design a tamper-proof solution based on blockchain-based traceability information of edible agricultural products suitable for system needs.Based on the analysis of blockchain technology principles,technical characteristics,blockchain technology development tools,especially the comparative analysis of different blockchain technology platforms,combined with the actual demand of wholesale market for the real and perfect traceability information,this thesis selects a blockchain technology platform that can better meet the needs of the developed system,and proposes a blockchain solutions that can prevent tampering of traceability information of edible agricultural products.(3)Research and develop the design and implementation of anti tampering of traceability information of edible agricultural products based on blockchain,and develop traceability system of edible agricultural products.Based on the analysis and selection of the front and back technology of system development,this thesis analyzes the requirements,system design,system implementation and system deployment of the system from the perspective of software engineering methods,and briefly presents the use case analysis,data flow diagram and database design of the whole system,including the brief introduction of the three main subsystems of the system,the main function module structure of the system,etc.This thesis focuses on the detailed design,implementation and system test of the anti tampering module of traceability information of edible agricultural products based on blockchain,including the detailed introduction of the four levels of design of the module,the software environment needed for development,the specific implementation of the module and the implementation effect of other modules of the system.
