Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a blockchain-based traceability data rating system and method thereof. 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 agricultural product ratings in traceability information has become an urgent problem to be solved. Summary of the invention

[0004] The main purpose of the present invention is to provide a blockchain-based traceability data rating system and method to solve the problem of how to ensure the authenticity and effectiveness of agricultural product ratings.

[0005] According to one aspect of the present invention, a traceability data rating system based on blockchain is proposed, which includes: a setting module, used to collect product characteristic information and component information contained in a preset component library, and set the characteristic information and component association logic; wherein the component library includes multiple components for constituting a picture; an upload module, used to put the component library on the chain; a deployment module, used to deploy a smart contract on the chain, wherein the smart contract includes a rating logic and a component association logic for scoring the characteristic information of the product; wherein the smart contract rates the characteristic information of the product on the chain according to the rating logic, searches for the corresponding component in the component library according to the rating result and the component association logic, and obtains the component address on the chain.

[0006] Among them, the traceability data rating system also includes: an event monitoring module, which is used to call the smart contract to execute product rating after monitoring the chain event notification of product traceability information.

[0007] The rating logic includes: determining the product level according to the basic score and weight ratio of each characteristic information, wherein the basic score is related to the rarity of the product.

[0008] The smart contract determines the corresponding component according to the characteristic information, component association logic and rarity.

[0009] If there are multiple components, the smart contract randomly selects one of them.

[0010] According to another aspect of the present invention, a traceability data rating method based on blockchain is proposed, which includes: collecting product characteristic information and component information contained in a preset component library, and setting component association logic between the characteristic information and the components; wherein the component library includes multiple components for constituting a picture; putting the component library on the chain; deploying a smart contract on the chain, wherein the smart contract includes a rating logic and a component association logic for scoring the characteristic information of the product; wherein the smart contract rates the characteristic information of the product on the chain according to the rating logic, and searches for the corresponding component in the component library according to the rating result and the component association logic, and obtains the component address on the chain.

[0011] Among them, the traceability data rating method also includes: after monitoring the chain event notification of product traceability information, calling the smart contract to execute product rating.

[0012] The rating logic includes: determining the product level according to the basic score and weight ratio of each characteristic information, wherein the basic score is related to the rarity of the product.

[0013] The smart contract determines the corresponding component according to the characteristic information, component association logic and rarity.

[0014] If there are multiple components, the smart contract randomly selects one of them.

[0015] According to the technical solution of the present invention, by deploying it on the blockchain in the form of a smart contract for trusted execution according to the set logic, and displaying the rules on the final consumer side, the disadvantage of the traditional rating method that the administrator can modify the original data and rating rules at will is avoided.

[0021] 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.

[0022] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] According to an embodiment of the present invention, a traceability data rating system based on blockchain is provided, which is applicable to the fields of breeding, animal husbandry, agriculture and animal husbandry. Figure 1 As shown, the system at least includes:

[0024] The setting module 10 is used to collect the characteristic information of the product and the component information contained in the component library, and set the component association logic of the characteristic information and the component. Among them, the characteristic information of the product can also be called traceability information, including data such as brand, process, production link, environment, quality, etc. The component library is a pre-set database including multiple components for constituting a picture. The component is a fragment that constitutes a picture, and multiple components can be spliced ​​into a picture. The component association logic is also called characteristic component association logic, including the association relationship between characteristic information and components.

[0025] The uploading module 20 is used to upload the component library to the component chain.

[0026] The deployment module 30 is used to deploy a smart contract on the component chain, wherein the smart contract includes a rating logic and a component association logic for scoring the product's characteristic information. The rating logic includes: a basic score corresponding to the characteristic information, a weight of the characteristic information, and a rarity of the characteristic information.

[0027] Among them, the smart contract performs product rating on the characteristic information of the product traceability information on the chain according to the rating logic, and searches for the corresponding component in the component library according to the rating result and the component association logic, and obtains the component address on the chain.

[0028] The smart contracts in this application are also called chaincodes or application codes. They 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 data in the state database.

[0029] The details of the above-mentioned processing are described below.

[0030] refer to Figure 2 Before the traceability begins, the system needs to collect the characteristic information of the traceable products to be tracked and the component information contained in the component library, and set their association logic. Among them, the characteristic information of the product is uploaded to the traceability chain. For example, taking "rice" as an example, the characteristic information may include: soil environmental quality, variety type, planting cycle, proportion of organic fertilizer, water source water quality and other information; taking "cattle and sheep breeding" as an example, the characteristic information may include: variety type, breeding years, feed type, origin, etc. For meat products, component types may include: head, trunk, etc., and according to the degree of rarity, the component types can be further divided into: extremely rare, rare, special, ordinary, etc., such as "trunk-rare", "head-special", etc.

[0031] For traceability, select a suitable smart contract and deploy it on the component chain. The smart contract mainly includes two functions: product rating and component association logic. After the contract is deployed, register the event monitoring service in the system's event monitoring module. The service specifies the traceability chain address to be monitored and associates it with the deployed contract. The chain message of product characteristic information can be monitored through the traceability chain address.

[0032] The smart contract receives the characteristic information of a product, including: A, B, C (breeding cycle), and the actual values ​​of D (A1, B1, C1, D1). The smart contract processes each characteristic data in turn.

[0033] Combined with reference Figure 3 , the algorithm and calculation process of the example are as follows:

[0034] 1. After receiving data C1, determine the data range to which C1 belongs based on the association logic, and classify the data according to its rarity. The result is "rare", and the basic score is 3.

[0035] 2. Add the trait basic score and the trait rating ratio of 20% to get a trait score of 0.6.

[0036] 3. Similarly, rate the values ​​A1, B1, and D1, assuming that the corresponding rating scores are 1.2 / 0.9 / 0.3.

[0037] 4. The final product score is (1.2+0.9+0.6+0.3) / 4*100=75.

[0038] After rating the trait data, the basic score is 3, and the system will make visual associations based on this. For example, if the rarity score of the trait "breeding cycle" is known to be 3, and the associated component type of the trait is known to be "trunk", the system will randomly select a component from all components with the attribute "trunk-rare" and return the on-chain storage address P of the component. Repeat the above steps to find the on-chain address of the corresponding component of each trait, and finally obtain the component address set P1. Then, upload the components of the component library to the blockchain for storage, and then send a request to the component chain according to the component address and obtain the corresponding component, and call the generate image function to synthesize multiple components into a complete image corresponding to the product.

[0039] It should be noted that the traceability chain and component chain mentioned above are both blockchains, and this application uses different naming methods according to their different functions. The type of blockchain can be a private blockchain or a consortium blockchain.

[0040] Figure 4 is a flowchart of a blockchain-based traceability data rating method according to an embodiment of the present invention. Figure 4 As shown, the method comprises the following steps:

[0041] Step S402, collecting product characteristic information and component information contained in a preset component library, and setting component association logic between the characteristic information and the components; wherein the component library includes a plurality of components for forming a picture;

[0042] Step S404, putting the component library on the chain;

[0043] Step S406, deploying a smart contract on the chain, wherein the smart contract includes a rating logic and a component association logic for scoring the characteristic information of the product;

[0044] Among them, the smart contract rates the product characteristics information of the product on the chain according to the rating logic, searches for the corresponding component in the component library according to the rating result and the component association logic, and obtains the component address on the chain.
