Research On Application Of Muscovy Duck Food Traceability Based On Blockchain

With the improvement of people's quality of life and the gradual development of a new generation of information technology,people have higher and higher requirements for food quality,meanwhile,more attention has been paid to food quality information security.Food traceability involves all links from production to sales,and involves a large amount of information.The links in the traditional food traceability system are independent of each other,and information is not circulated,which easily forms information islands,resulting in complicated traceability processes and difficult traceability.The food traceability system is controlled by a centralized enterprise or institution.The information of each link of production,processing,and sales is all stored in the centralized system,which is easy to cause the risk of artificial alteration and attack on the stored data,resulting in incomplete,untrue,and unreliable traceability information.Low reliability.In order to ensure that consumers buy quality and safe food,it is necessary to establish a safe,reliable,open and transparent traceability system that is easy to trace.Block-chain has the technical characteristics of decentralization,non-tampering,traceability,openness and transparency,and distributed storage.It can solve the various shortcomings of current food quality traceability,improve traceability transparency,ensure the authenticity and effectiveness of data,realize information sharing,and strengthen Organic links between departments.Based on the implementation environment of the various components of the Muscovy Duck System,this article focuses on the problems and shortcomings of traditional food traceability methods,and studies the Muscovy Duck Food Traceability System based on block-chain technology.The main contents are as follows:(1)Analyze the importance of a food traceability system based on block-chain.Starting from the research background and significance,analyze the current research status of food traceability at home and abroad,point out the centralization,information islands,and low data credibility existing in traditional food traceability;analyze the principles of block-chain technology and the application of block-chain technology The superiority of food traceability points out the importance of block-chain technology for the traceability of muscovy duck food.(2)Build a dual auxiliary database system to store the basic information of Muscovy duck food and basic transaction information."Auxiliary database 1" is used to store information such as the corresponding block of the transaction information summary;"Auxiliary database 2" is used to store the basic information of the transaction(including the publisher,transaction ID,source file address),and the original transaction information(including pictures),Video)and other specific information,so as to solve the problem of high pressure on the existing block-chain system to store all transaction information.(3)Design of Muscovy Duck Food Traceability System Based on Block-chain.According to the implementation environment of the various components of the Muscovy duck system,the structure and scheme of the Muscovy duck food traceability system are designed.Hyper ledger Fabric is used as the underlying development platform.Each node uses a consensus algorithm to upload the food information summary on the chain,and adjusts it through the auxiliary database.Get the query to realize the traceability of Muscovy duck food.
