s8: a consumer (30) scans the tracing two-dimensional code by using electronic equipment and enters a tracing platform (51) in a P2P network (50), information of each processing link of the agricultural product is accessed and traced back to the whole supply chain, the consumer (30) scrapes the anti-counterfeiting layer and inputs the tracing code into a tracing code frame for authenticity query.
5. The method and process of claim 4, wherein the agricultural product tracing method and process based on the blockchain technology comprises: the business information in the steps S2, S3, and S6 each include a business name, a business address, and a contact phone, wherein the business address and the contact phone are visible only to the next-level process user.
6. The method and process of claim 4, wherein the agricultural product tracing method and process based on the blockchain technology comprises: in the steps S1 to S8, a certain processing user can only edit the information of the processing user at the stage, and cannot modify the information of the processing user at the previous stage or the processing user at the next stage, and the raw material processing information is in a confidential state and can be checked only by the processing user at the stage corresponding to the raw material processing information and the monitoring department (40).
7. The method and process of claim 4, wherein the agricultural product tracing method and process based on the blockchain technology comprises: the raw material information in the steps S1-S8 includes product name, product weight, product batch, product description and pictures of the product with the traceable two-dimensional code.
8. The method and process of claim 4, wherein the agricultural product tracing method and process based on the blockchain technology comprises: the evaluations in the steps S4 and S6 are public status, and can be viewed by any level of processing users and consumers (30) as well as the regulatory body (40).
