Detailed Description
Hereinafter, the implementation principle and the preferred embodiment of the present invention will be described in detail by taking the construction of the traceability system of yellow croaker product quality based on fabric technology as an example.
As shown in fig. 5, in the fabric network, several yellow croaker farming, production and processing cooperative enterprises create a blockchain shared account book linked up and down in an industrial chain, related core enterprises and representative enterprises are defined as endorser and deploy endorser nodes, and other related enterprises are used as common participating enterprises and deploy peer nodes. Starting from a source enterprise of an industrial chain, creating traceability data of the product in a public ledger; and then, the enterprise taking the product as a raw material creates own product traceability data according to the own product batch, the enterprise ID and the raw material product ID. Meanwhile, related chain codes of product traceability information creation, data updating and traceability data query are deployed in the public ledger.
In the system, in each production and processing process, production and processing data of the product are submitted within a set time interval, for example, the contents of relevant additives such as sugar, salt, ammonium nitrite and the like for preventing the yellow croaker from corrosion are submitted in the production process of the yellow croaker can, and after the processing data are submitted, the chain code updates the current quality state of the product in real time according to the updated data.
