Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a blockchain-based traceability product visualization display system and method. Background Art

[0002] As people's living standards continue to improve, the concept of pursuing a healthier and greener diet has gradually gained popularity. Modern agriculture has gradually changed from the rough model of the past to a refined agricultural model. Foods labeled with organic vegetables, pure grain-fed beef, mutton and pork have become more popular. Since these labeled agricultural products are different from ordinary agricultural products in terms of production and breeding, their quality is also better. Consumers are very willing to pay for agricultural products that "match quality and price". However, as the terminal of the entire economic cycle, consumers cannot directly observe the entire production environment process of the purchased agricultural products. Some unscrupulous merchants often take advantage of this information blind spot to "pass inferior goods off as good ones" and "pass fake goods off as real ones" to make high profits. Counterfeiting methods are also emerging in an endless stream. "Fake labels" and "real labels and fake goods" have caused consumers to be skeptical of agricultural products such as "green", "organic" and "pure grain-fed", which has greatly hit the market's confidence in high-value-added agricultural products and destroyed the market order and the high-quality cycle of economic development.

[0003] Therefore, agricultural product information traceability plays an extremely important role in the development of modern agriculture. How to ensure the authenticity of traceability information and how to display traceability information credibly have become urgent issues to be resolved. Summary of the invention

[0004] The main purpose of the present invention is to provide a blockchain-based traceability product visualization display system and method to solve the problem of how to display traceability information in a credible manner.

[0005] According to one aspect of the present invention, a traceability product visualization display system based on blockchain is proposed, which includes:

[0006] An index establishment module is used to establish an index and upload it to the chain, wherein the index uses K as the primary key and A, G, P and E as values; wherein K is a unique identifier, G is a set of production environment information data for the product, E is a product rating obtained based on G, P is a set of on-chain addresses of multiple components corresponding to G, A is an image X generated by multiple components corresponding to P, and X is saved as an on-chain address of NFT storage; a query request receiving module is used to receive a query request from a client, wherein the query request contains the primary key K; a query module is used to obtain A, G, P, E and X through the chain according to the primary key K contained in the query request, and send A, G, P, E and X to the client.

[0007] The system further includes: an image generation module, which is used to send a request to the chain according to P to obtain corresponding multiple components, generate an image X according to the multiple components, and upload the image X to the chain.

[0008] Among them, the smart contract is provided with a rating logic for scoring the production environment information data set.

[0009] Among them, the on-chain address set P is the address set of multiple components in the component library stored on the chain.

[0010] According to another aspect of the present invention, a visual display method for traceability products based on blockchain is proposed, which includes: establishing an index and uploading it to the chain, wherein the index uses K as the primary key and A, G, P and E as values; wherein K is a unique identifier, G is a set of production environment information data of the product, E is a product score obtained according to G, P is a set of on-chain addresses of multiple components corresponding to G, A is an image X generated by the corresponding multiple components obtained according to P, and X is saved as an on-chain address of NFT storage; receiving a query request from a client, wherein the query request contains the primary key K; obtaining A, G, P, E and X through the chain according to the primary key K contained in the query request, and sending A, G, P, E and X to the client.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] According to an embodiment of the present invention, a traceability product visualization display system based on blockchain is provided, which is applicable to the fields of breeding, animal husbandry, agriculture and animal husbandry. Figure 1 , the system at least comprises:

[0022] An index building module 10 is used to build an index and upload it to the chain, wherein the index uses K as the primary key and A, G, P and E as values; wherein K is a unique identifier, G is a set of production environment information data of the product, E is a product rating obtained according to G, P is a set of on-chain addresses of multiple components corresponding to G, A is an image X generated by multiple corresponding components obtained according to P, and X is saved as an on-chain address stored in an NFT (Non-Fungible Token) storage chain;

[0023] A query request receiving module 20, configured to receive a query request from a client, wherein the query request includes a primary key K;

[0024] The query module 30 is used to obtain A, G, P, E and X through the chain according to the primary key K contained in the query request, and send A, G, P, E and X to the client.

[0025] During the production process, the farm will collect the production environment information data required for traceability, upload the traceability product production environment information to the traceability chain through the information collection registration node, and bind it to the unique primary key K. In this step, the farm can keep up with the production process and store the generated data one by one on the chain, or store them all on the chain after production is completed. In this step, there may be a situation where the time-consuming logistics and transportation is also a traceability feature. In this case, the subsequent process will also be executed after the data is complete.

[0026] After receiving the data storage request and completing the storage, the primary key K of the traceability chain will check whether the data collection is completed. If completed, the event notification service will be triggered to send the primary key K and the production environment information data set G to the system's event listening service. After receiving the message, the system's listening service will call the corresponding smart contract with G as a parameter to obtain the product rating E and the component address set P found from the component library. It should be noted that smart contracts, also known as chaincodes or application codes, are programs deployed in the nodes of the blockchain network. The nodes execute the smart contracts called in the received transactions to update or query the key-value pairs of the state database. The smart contract mainly includes the rating logic for scoring the production environment information data set, and the association logic of the relationship between the characteristic information and the components.

[0027] After the system obtains the component address returned by the smart contract, it sends a request to the component chain and obtains the component. Then it calls the image generation function to combine the components into a complete image X. After the image generation is completed, it sends a request to the NFT storage chain, saves the generated image as an NFT, and returns the on-chain address A stored on the NFT storage chain.

[0028] After the system receives the on-chain address A returned by the NFT storage chain, it executes the index transaction and stores it on the component chain, where the index transaction uses K as the primary key and A, G, P, and E as values.

[0029] The user downloads and installs the smartphone traceability terminal (APP) or WeChat mini program, scans the QR code, and the APP or mini program sends a query request to the system, where the request parameters include the primary key K contained in the QR code.

[0030] After receiving the transaction request, the system initiates a query request to the component chain with K as the parameter, obtains A, G, P and E, and then obtains X stored on the NFT storage chain based on A. Among them, the product introduction is obtained through G, the rarity value is obtained through E, and the data corresponding to P is saved in the database for the next step. The obtained data is returned and displayed to the user as the scan code homepage. Figure 2 When a user clicks on a component, the system receives the request, finds the corresponding component image based on P, and then, based on the trait component association logic, reverses the corresponding trait in G and its value and trait rating, returns the obtained data, and displays it to the user as a component information page.

[0031] The traceability chain, component chain and NFT storage chain mentioned above are all blockchains. This application adopts different naming methods according to their different functions. The type of blockchain can be private blockchain or consortium blockchain.

[0032] Figure 3 is a flowchart of a visual display method for traceability products based on blockchain according to an embodiment of the present invention. Figure 3 As shown, the method comprises the following steps:

[0033] S302, create an index and upload it to the chain, where the index uses K as the primary key and A, G, P and E as the values; K is a unique identifier, G is a data set of the product's production environment information, E is a product rating obtained based on G, P is a set of on-chain addresses of multiple components corresponding to G, A is an image X generated by multiple components obtained based on P, and X is saved as an on-chain address for NFT storage;

[0034] S304, receiving a query request from a client, wherein the query request includes a primary key K;

[0035] S306, obtaining A, G, P, E and X through the chain according to the primary key K included in the query request, and sending A, G, P, E and X to the client.

[0036] The method further includes: sending a request to the chain according to P to obtain a corresponding plurality of components, generating an image X according to the plurality of components, and uploading the image X to the chain.

[0037] Among them, the smart contract is provided with a rating logic for scoring the production environment information data set.

[0038] Among them, the on-chain address set P is the address set of multiple components in the component library stored on the chain.
