A detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this disclosure.

Figure 1 schematically shows a flow chart of a certification qualification issuance method provided by the present disclosure, which is applied to certification nodes in a blockchain system. The method includes:

Step 101: Receive a material authentication request for materials sent by the first target node in the blockchain system.

In the embodiment of the present disclosure, the certification node is a node in the blockchain system used to issue certification qualifications to other nodes. The certification node can also participate in the consensus mechanism in the blockchain system. The first target node can be any ordinary node in the blockchain system except the certification node, and its owner can hold the materials needed to make products, such as puree wine, juice puree, electronic components, etc. After obtaining the material, the owner of the first target node can request the certification node to issue certification qualifications for the material by sending a material certification request for the obtained material to the blockchain.

Step 102: When the identity authentication of the first target node passes, issue homogenization tokens corresponding to the material to the first target node.

It should be noted that a Fungible Token (FT, Fungible Token) is a decentralized token that has the same value and can be split. Fungible tokens that follow the same token protocol can achieve Fungible Tokens. Transaction replacement between coins, such as Ethereum's ERC 20 protocol, which stipulates that tokens sent under the ERC 20 protocol on the Ethereum platform can be freely exchanged.

In this disclosed embodiment, the prerequisite for issuance of qualifications is that the authentication node needs to verify that the identity of the first target node is legal. That is to say, although the authentication node is responsible for issuing qualifications during qualification authentication, the first target node must access the qualification every time. Blockchains require the certification nodes on the blockchain to reach a consensus on their identity authentication to ensure that the identity of the first target node is legal.

In the embodiment of this disclosure, the qualification certification carrier of the materials provided by the certification node is a homogeneous token. As a decentralized token, the homogeneous token has the characteristics of being divisible and equivalently exchangeable, and can be applied to Materials can be divided and equivalent. For example, puree wine can be blended and split according to any proportion, and puree wines with the same blending ratio have the same value, or fruit juice purees of the same variety can be blended to adjust the concentration. , and equal parts of juice puree have the same value. By using homogeneous tokens to carry the certification qualifications of materials, the flow and usage of each share of materials can be accurately tracked to prevent cross-stocking. Consumers can check at any time by scanning the QR code. It is safe and trustworthy, and the pass can be checked.

Step 103: Receive a product certification request for a product made from the material sent by the second target node in the blockchain system, where the product certification request at least includes production information of the homogeneous token.

It should be noted that the second target node is similar to the first target node. The first and second descriptions are used here only to facilitate the distinction. In practical applications, the first target node and the second target node may be the same The nodes can also be different nodes, which can be set according to actual needs, and are not limited here.

In this disclosed embodiment, the owner of the second target node can send a product certification request to the blockchain and carry the materials used to make the product after homogenizing the materials after the token certification qualification to produce the finished product. The production information of the homogeneous token is used to request the certification node to issue the certification qualification of the product. Among them, the production information is the usage of materials used by the homogeneous token in the product production process.

Step 104: When the identity authentication of the second target node is passed and the production information of the homogeneous token is verified, the non-fungible token corresponding to the product is issued to the second target node. Token.

It should be noted that non-fungible tokens (NFT, Non-Fungible Token) are unique digital tokens that cannot be interchanged with any other NFT. In related technologies, the ERC721 protocol standard can usually be used to issue non-fungible tokens. Fungible Token, ERC721 It was originally created by CryptoKitties and is also the first standard to represent non-fungible digital assets. ERC721 is an inheritable Solidity smart contract standard. One can easily inherit from the OpenZeppelin library and use it for programming NFT-based projects.

In this disclosed embodiment, as described above, before issuance of qualifications, the authentication node needs to pass the identity authentication of the second target node to ensure that the identity of the second target node is legal. Furthermore, the homogeneous tokens need to be verified to ensure that the materials used in the products prepared by the second target node are materials certified by the blockchain system to avoid the legality of the product materials. Furthermore, taking into account the uniqueness of the products for sale, the certification node uses non-fungible tokens to carry the certification qualification of the finished product, thereby ensuring the uniqueness of the certification qualification of each product, so that consumers can pass the block The information of each product in the product life cycle can be queried through the chain, realizing information tracking and traceability throughout the product life cycle.

This disclosure builds a blockchain system composed of target nodes of participants in the product generation process and third-party certification nodes, so that the certification node is responsible for verifying the identity of the target node, and the certification node adapts to the material detachability. The characteristic is to issue homogeneous tokens that also have divisible characteristics as the certification qualification of the material, and after verifying the homogeneous tokens of the materials used to make the product, issue non-fungible tokens that are adapted to the unique characteristics of the product as the product certification qualifications, thereby flexibly achieving qualification certification for the entire product life cycle from materials to products.

In the embodiment of the present disclosure, the blockchain system may also include a supervision node. The supervision node is a node and smart contract responsible for managing and coordinating the blockchain. It is usually owned by the builder of the blockchain, while the certification node is an intermediary. As a third-party node between the supervision node and the ordinary node, the introduction of this node is mainly due to the possible storage of interest relationships between the supervision node and the ordinary node, or the supervision node only provides blockchain system support and cannot directly control ordinary nodes. The products provided come with valid certification qualifications. For example, in industries such as commercial wine, food, and electronic products, the providers of supervision nodes may be just service providers with low credibility for commodities. Therefore, commodity industry supervision agencies or units with higher credibility for commodities can be introduced. As a third party responsible for certifying nodes, we provide qualification certification for goods or materials provided by ordinary nodes.

Optionally, referring to Figure 2, step 102 includes:

Step 1021: Generate a material code associated with the homogeneous token.

Step 1022, associate and store the material code and the homogeneous token in the blockchain.

Step 201: Receive a material production request sent by the third target node in the blockchain system. The material production request at least includes: the material coding and production information of the homogeneous token.

Step 202: When the identity authentication of the third target node is passed and the material encoding is passed, the production information is recorded in the circulation record of the homogeneous token on the blockchain.

The third target node is similar to the second target node and will not be described again here.

In the embodiment of the present disclosure, when the material owner splits the material, he or she can request the certification node to perform qualification certification by carrying the material coding and production information of the material's homogeneous token to the blockchain method. For example, referring to Figure 4, when a wine company sells a part of the puree wine to other companies, it can send the material to the blockchain carrying the material code of the puree wine and production information such as blending and finished wine. Make a request to request certification node certification qualifications.

Furthermore, the certification node can certify the material code by querying the hash value of the homogeneous token and material code on the blockchain, and upload the production information of this split process to the block after passing the certification. The circulation record of homogeneous tokens on the chain can reach a consensus on the split process on the blockchain.

Optionally, referring to Figure 5, the method further includes:

Step 301: Receive a material information query request sent by the fourth target node in the blockchain system. The material information query request at least includes: the material code.

Step 302: When the identity authentication of the fourth target node is passed, obtain each production information in the circulation record of the homogeneous token corresponding to the material code.

Step 303: Send the production information to the fourth target node.

For example, assuming that the material is puree wine, the material code can be represented in the form of a QR code. The QR code for the storage and traceability of the puree wine can be identified by scanning the code at the terminal. Since there is a blending process for splitting the puree wine , tokens can be issued in the form of FT. Each token is anchored to the entire bottle of puree wine and can be split at will. The split token is anchored to the specific flow of puree wine, which can accurately record each The whereabouts and related data of a share of puree wine.

Optionally, referring to Figure 6, step 103 includes:

Step 1031: Generate a product code associated with the non-fungible token.

Step 1032, associate and store the product code and the non-fungible token in the blockchain.

Step 1033: Issue non-fungible tokens corresponding to the product to the second target node, and send the product code to the second target node.

In the embodiment of the present disclosure, the certification node will generate a unique product code corresponding to the non-fungible token when issuing non-fungible tokens, and store the hash value of the non-fungible token and the product code to the blockchain, and provide the second target node with the product code, so that the non-fungible tokens are not directly exposed, but use the product code as an index to query the products corresponding to the corresponding non-fungible tokens information, improving the security of non-fungible tokens.

Optionally, referring to Figure 7, the method further includes:

Step 401: Receive a product transaction request sent by the fifth target node in the blockchain system. The product transaction request at least includes: the product code and transaction information of the non-fungible token.

Step 402: When the identity authentication of the fifth target node is passed and the product code verification is passed, the transaction information is recorded in the circulation record of the non-fungible token on the blockchain. .

The fifth target node is similar to the second target node and will not be described again here.

In this disclosed embodiment, when the owner of a product trades the product, he or she can request the certification node for qualification certification by carrying the product coding and production information of the non-fungible token of the product to the blockchain method. Furthermore, the certification node can certify the product code by querying the hash value of the non-fungible token and product code on the blockchain, and upload the transaction information of this transaction process to the block after passing the certification. The circulation record of non-fungible tokens on the chain, thereby reaching a consensus on the transaction process on the blockchain. For example, referring to Figure 8, the blockchain will continue to record various product-related information through the entry of transaction information throughout the entire product cycle from the production, logistics, and distributors of commercial wine to consumer purchase.

Optionally, referring to Figure 9, the method further includes:

Step 501: Receive a product information query request sent by the sixth target node in the blockchain system, where the product information query request at least includes: the product code.

Step 502: When the identity authentication of the sixth target node is passed and the product code is passed, the transaction information in the circulation record of the non-fungible token associated with the product code is queried.
