The embodiment of the invention provides a food material traceability system, method and equipment based on a block chain and a storage medium, and relates to the technical field of block chains. The system comprises a display layer used for display and interaction of the system; the application layer comprises registration and registration of roles on a food material supply chain and operation of traceability related function service; the service layer is used for data interaction operation between the traceability system and the data layer block chain; and the data layer is used for roles on the food material supply chain to read and write data stored in the data layer through the application layer and the service layer. According to the embodiment of the invention, by means of a block chain technology, a cooperation mechanism of each role of a school food material supply chain is established, information islands of each role are communicated, credible traceability of food material commodities is realized, a user can master the whole process of school food material circulation, the public and supervision agencies can obtain high-quality traceability service of school canteen food materials, and the user experience is improved. A transparent and credible school food material traceability system is constructed, and a virtuous circle of food health is realized.
Description
technical field [0001] This application relates to the technical field of block chain, specifically, this application relates to a food traceability system, method, device and storage medium based on block chain. Background technique [0002] Food safety issues are related to people's health. In recent years, the frequent occurrence of food safety issues has attracted widespread public attention, making food traceability gradually a rigid social need. Food safety is an important basis for food safety, especially in school cafeterias. Food safety directly affects food hygiene and safety on students' dining tables. [0003] The existing product traceability technology is mainly composed of software and hardware technologies. By pasting labels on product packaging, such as quality certification, barcodes, QR codes, etc., information is collected and uploaded by IoT devices such as RFID, NFC, and smart terminals. , to realize the reverse traceability of the commodity supply ch...
