Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, based on the embodiments in this disclosure are intended to be within the scope of this disclosure.

Fig. 1 schematically illustrates a flowchart of an authentication qualification issuing method provided by the present disclosure, applied to an authentication node in a blockchain system, where the method includes:

step 101, receiving a material authentication request for a material sent by a first target node in the blockchain system.

In the disclosed embodiment, the authentication node is a node in the blockchain system for issuing authentication qualifications to other nodes, which may also participate in a consensus mechanism in the blockchain system. The first target node may be any common node in the blockchain system other than the authentication node, and its owner may hold materials required for making the product, such as wine, juice puree, electronic components, etc. After obtaining the material, the owner of the first target node may request the authentication node to issue an authentication qualification for the material by sending a material authentication request for the obtained material to the blockchain.

Step 102, issuing a homogenizing token corresponding to the material to the first target node when the identity authentication of the first target node is passed.

It should be noted that a homogeneous Token (FT) is a valuable and detachable decentralized Token, and for a homogeneous Token that follows the same Token protocol, a trade replacement between homogeneous tokens, such as the ERC 20 protocol of ethernet, may be implemented, and the protocol specifies that the tokens sent in the ERC 20 protocol on the ethernet platform may be freely exchanged.

In the embodiment of the disclosure, the precondition of issuing qualification is that the authentication node needs to verify that the identity passing through the first target node is legal, that is, the authentication node is responsible for issuing during qualification authentication, but the authentication node on the blockchain needs to agree on the identity authentication of the first target node every time the first target node accesses the blockchain, so as to ensure that the identity of the first target node is legal.

The qualification certification carrier of the material provided by the certification node in the embodiment of the disclosure is a homogenized token, the homogenized token is used as a de-centralized token, has the characteristics of splitting and equivalent exchange, and can be suitable for the characteristics that the material can be split and equivalent, for example, the raw juice wine can be blended and split according to any proportion, and the values of the raw juice wine with the same blending proportion are the same, or the juice raw juice with the same variety can be blended to adjust the concentration, and the equal parts of the juice raw juice have the same value. The flow direction and the service condition of each share of materials can be finely tracked by utilizing the homogeneous token to bear the authentication qualification of the materials, the channeling is prevented, the code scanning of consumers can be checked at any time, the safety and the reliability are ensured, and the communication certificate can be checked.

Step 103, receiving a product authentication request for a product manufactured by the material sent by a second target node in the blockchain system, wherein the product authentication request at least comprises manufacturing information of the homogenized token.

It should be noted that, the second target node is similar to the first target node, and only for convenience of distinguishing the first and second descriptions, in practical application, the first target node and the second target node may be the same node or different nodes, specifically may be set according to practical requirements, and are not limited herein.

In the embodiment of the disclosure, after the owner of the second target node makes a commodity obtained by making a finished product from the material after the qualification of the homogenized token, the owner may request the authentication node to issue the qualification of the product by sending a product authentication request to the blockchain and carrying the making information of the homogenized token of the material used for making the product. Wherein the manufacturing information is the use condition of materials used in the manufacturing process of the homogeneous token.

Step 104, issuing the non-homogeneous tokens corresponding to the products to the second target node when the identity authentication of the second target node is passed and the production information of the homogeneous tokens is verified.

It should be noted that Non-homogeneous Token (NFT) is a unique digital Token that cannot be interchanged with any other NFT, and that the ERC721 protocol standard is commonly used in the related art to issue Non-homogeneous tokens, ERC721 originally created by cryptokittes, is the first standard to represent Non-homogeneous digital assets. ERC721 is an inheritable intelligent contract standard for resolution. One can easily inherit from the OpenZeppelin library and use it to program NFT-based items.

In the embodiment of the disclosure, as described above, the authentication node needs to pass the identity authentication of the second target node before issuing qualification, so as to ensure that the identity of the second target node is legal. Furthermore, verification of the homogenized token is required to pass, so that the material used by the product prepared by the second target node is a material qualified and authenticated by the blockchain system, and the legality of the material of the product is avoided. Further, considering the uniqueness of the products for sale, the authentication node adopts the non-homogeneous token to bear the authentication qualification of the finished products, so that the uniqueness of the authentication qualification of each product is ensured, and therefore, a consumer can inquire the information of each product in the life cycle of the product through a blockchain, and the information tracking and tracing of the full life cycle of the product are realized.

The method and the system have the advantages that the blockchain system consisting of the target node of the participator in the production process of the product and the authentication node of the third party is constructed, so that after the authentication node takes charge of authenticating the identity of the target node, the authentication node is adapted to the material splitting characteristic to issue the homogeneous token with the splitting characteristic as the authentication qualification of the material, and after the homogeneous token of the material for producing the product is verified, the non-homogeneous token adapted to the unique characteristic of the product is issued as the authentication qualification of the product, and thus the qualification authentication of the whole product life cycle from the material to the product is flexibly realized.

In the embodiment of the disclosure, a supervisory node may be further included in the blockchain system, where the supervisory node is a node responsible for managing and coordinating the blockchain and an intelligent contract, and is generally owned by a constructor of the blockchain, and the authentication node is a third party node between the supervisory node and a common node, and the introduction of the node mainly considers possible storage benefit relationship between the supervisory node and the common node, or the supervisory node only provides support for the blockchain system, and cannot directly provide effective authentication qualification for products provided by the common node. For example, in industries such as commodity wine, food, electronic products and the like, the provider of the supervision node may be just a service provider, and the degree of trust for the commodity is low, so that a commodity industry supervision organization or a unit with high degree of trust for the commodity can be introduced as a third party responsible authentication node to provide qualification authentication for the commodity or the material provided by the common node.

Optionally, referring to fig. 2, the step 102 includes:

step 1021, generating a material code associated with the homogenized token.

Step 1022 stores the material encoding and the homogenized token association to the blockchain.

Step 1023, issuing a homogenized token corresponding to the material to the first target node, and sending the material code to the first target node.

In the embodiment of the disclosure, the authentication node generates a unique material code corresponding to the homogenizing token when the homogenizing token is issued, stores hash values of the homogenizing token and the material code into the blockchain, and provides the material code to the first target node, so that the homogenizing token is not directly exposed, but the corresponding homogenizing token is queried by taking the material code as an index, and the safety of the homogenizing token is improved.

Optionally, referring to fig. 3, the method further includes:

step 201, receiving a material making request sent by a third target node in the blockchain system, where the material making request at least includes: the material encoding and manufacturing information of the homogenized tokens.

Step 202, recording the production information in a circulation record of the homogenized token on the blockchain when the identity of the third target node passes and the material is encoded.

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

In the disclosed embodiments, when the material is split, the owner of the material may request the authentication node to perform qualification authentication by carrying the material encoding and production information of the homogeneous tokens of the material to the blockchain method. For example, referring to FIG. 4, when a wine enterprise is selling a portion of a raw wine to other enterprises, the authentication node may be requested to authenticate qualification by sending a material code carrying the raw wine and a material making request to the blockchain to make information, such as blending, making a finished wine, etc.

Further, the authentication node can authenticate the material code by inquiring the hash value of the homogenizing token and the material code on the blockchain, and upload the manufacturing information of the splitting process to the circulation record of the homogenizing token on the blockchain after the authentication is passed, so that consensus is achieved on the blockchain for the splitting process.

Optionally, referring to fig. 5, the method further includes:

step 301, receiving a material information query request sent by a fourth target node in the blockchain system, where the material information query request at least includes: and the materials are encoded.

Step 302, when the identity authentication of the fourth target node is passed, obtaining each piece of production information in the circulation record of the homogenous tokens corresponding to the material codes.

In the embodiment of the present disclosure, the fourth target node is adapted to the recording process of the production information from step 201 to step 202, and can query all the circulation records of the materials associated with the homogenized tokens corresponding to the material codes, thereby realizing the accurate tracking and tracing of the material flowing process.

And step 303, sending the production information to the fourth target node.

The method is characterized in that the material is original pulp wine, the material coding can be represented through a two-dimensional code mode, original pulp wine is stored and traced to the source two-dimensional code, the terminal code scanning can be used for identification, and due to the fact that an original pulp wine splitting blending link exists, the FT mode can be adopted to send out pass certificates, each pass certificate is anchored with the original pulp wine in the whole jar, the pass certificates can be split randomly, the split pass certificates are anchored with the original pulp wine in a specific flow direction, and the direction and related data of each share of original pulp wine can be recorded accurately.

Optionally, referring to fig. 6, the step 103 includes:

step 1031, generating a product code associated with the non-homogenized token.

Step 1032 stores the product code and the non-homogenous token association to the blockchain.

Step 1033, issuing a non-homogenous token corresponding to the product to the second target node and transmitting the product code to the second target node.

In the embodiment of the disclosure, the authentication node generates a unique product code corresponding to the non-homogeneous token when the non-homogeneous token is issued, stores hash values of the non-homogeneous token and the product code into the blockchain, and provides the second target node with the product code, so that the non-homogeneous token is not directly exposed, but the product code is used as an index to inquire product information corresponding to the non-homogeneous token, and the security of the non-homogeneous token is improved.

Optionally, referring to fig. 7, the method further includes:

step 401, receiving a product transaction request sent by a fifth target node in the blockchain system, where the product transaction request includes at least: product coding and transaction information for the non-homogenous tokens.

Step 402, when the identity of the fifth target node is authenticated and the product code is verified, recording the transaction information in a circulation record of the non-homogenous tokens on the blockchain.

In embodiments of the present disclosure, the owner of a product may request qualification from an authentication node by carrying product encoding and production information for a non-homogenous token of the product to a blockchain method when the product is transacted. Further, the authentication node can authenticate the product code by inquiring hash values of the non-homogeneous token and the product code on the blockchain, and upload transaction information of the transaction process to a circulation record of the non-homogeneous token on the blockchain after the authentication is passed, so that consensus is achieved on the transaction process on the blockchain. For example, referring to FIG. 8, from the production of a commodity wine, logistics, dealer to the full product cycle of consumer purchase, the blockchain will keep track of various relevant information for the product through entry of transaction information.

Optionally, referring to fig. 9, the method further includes:
