A Method Of Pig Safety Traceability Based On Multi-blockchain

Pork is one of the most important daily foods in China.the quality and safety of pork are closely related to people's life and health.At present,the domestic pork safety situation is more severe.In recent years,there were big or small pork food safety accidents.There are many problems in the whole industry,such as more nodes in the industrial chain,less original production data,poor data reliability,information asymmetry,information island and so on.The industry lacks a unified and efficient regulatory platform and a credible traceability system.In order to solve the problem of pork food safety,we need to improve the pork food safety through the food traceability system.However,there is the problems of result authenticity in the traditional food traceability system,storage efficiency and cooperation.The task of this paper is to solve this problem.The purpose of this paper is to solve the problems of safety and cooperation,promotion of the whole industry chain and improvement of traditional food traceability in the pork food industry,design a feasible pork food traceability scheme,use the block chain network to make the data non tamperable,adding the block chain technology into the food traceability system,use the technical idea of cloud chain integration,and taking the block chain as the verification data: if the original data is generated,then the original data is stored in the database,the verification data is stored in the block chain,and the correctness of the data traceability result is ensured through the verification of the block chain during the querying of traceability.In this paper,through the research of pork industry chain,the method of food traceability of pork industry chain is proposed,the system framework is further implemented.In order to improve the popularization and practical in application of traceability system,we provide data mining services for the affiliated enterprises to protect their privacy and solve the problems of data privacy security and data island by using secure multi-party computing technology.According to the actual business situation of pork,the data mining method under secure multi-party computing is designed and tested.In view of the whole pork industry chain,a multi-chain system model design is proposed.Each link of pork is processed by a separate blockchain network,which reduces the data storage pressure of the blockchain network nodes and developed the whole enterprise participation of the pork industry app,for the porkindustry enterprise participation and use system,as the whole industry chain solution.
