Detailed Description
Hereinafter, the preferable embodiment of the method and the system is described by taking the example of constructing a multi-party evaluation system for agricultural products, namely a CNG agricultural chain seven-star evaluation model based on the method.
As shown in fig. 6, an intelligent contract for multi-party evaluation of agricultural products is designed according to fig. 6 based on an industry chain CNG agricultural chain oriented to agriculture as a bottom chain platform, and is deployed on the block chain platform, a distributed file storage system is constructed based on an SWARM technical architecture, evaluation links of agricultural products are set as multiple links according to the whole process of production and circulation of agricultural products, data acquisition points and a product identification description frame are defined for each link, a mobile phone client app is designed for data acquisition, and a two-dimensional code printer is deployed for printing identification of agricultural products.
The method is divided into seven value links according to the industrial value chain of agricultural products, wherein the seven links are respectively environment resources, production and processing, inspection and quarantine, storage and logistics, wholesale agency, retail processing and consumption users, each link is represented by a Beidou seven-star map, and the completeness of data of each link is identified by star brightness of each link. Each link is composed of one or more key value-added activities, the behaviors (or results) of the value-added activities of the links are mapped to a block chain to form data, and a non-falsifiable data chain is formed through a 'time stamp'.
In a CNG agricultural chain industrial data chain, each link participant uploads basic, production and operation data to form corresponding link data. Qualitative/quantitative evaluation analysis provided by the CNG agricultural chain seven-star evaluation model can truly present data of all links of the whole industrial chain, and consumers and users can be used as final evaluation and beneficiaries in the industrial data chain.
The CNG agricultural chain seven-star evaluation model is used as a value transfer tool, industrial data chain value information is delivered to a user and a consumer for judgment, the consumer participates in the CNG agricultural chain incentive model by judging 'doing work', and the evidence-based incentive promotes a customer installation terminal to apply and establishes an account number to participate in the CNG agricultural chain incentive model.
According to the CNG seven-star evaluation model, at each data acquisition point of an article, an operator automatically acquires a data acquisition template of the acquisition point through a data acquisition app, creates an article identifier and fills in related data, uploads and stores the data of the acquisition point into a distributed file system sweep and a block chain intelligent contract, clicks a print label, prints and outputs a two-dimensional code article label, and the article can be uniquely identified through the two-dimensional code label after the two-dimensional code label is bound with the article. The user obtains the data of the article to be inquired, the two-dimension code can be scanned through the mobile phone, the intelligent contract and the distributed file system storage information corresponding to the article can be automatically linked, the system automatically presents the data acquisition and uploading state of each link, and the agricultural product traceability information inquiry is realized.
The above description is only an illustration of the embodiments of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
