Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, the terms "inner", "outer", "longitudinal", "lateral", "upper", "lower", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are for convenience only to describe the present invention without requiring the present invention to be necessarily constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
embodiment 1 of the present invention provides an anti-counterfeiting and right-confirming method based on a block chain NFT technology, which specifically includes, as shown in fig. 1:
step 201: acquiring commodity information and storing the commodity information on a block chain platform;
the commodity represents any physical commodity which can be traded, for example: artware, artwork or agricultural products and the like. According to the practical situation, the physical commodities are different, and the information of the corresponding physical commodities stored on the blockchain platform is different, and from the purpose of the embodiment of the present invention, the stored commodity information is only compared with the commodity purchased by the buyer, for example: when the agricultural product is used, the corresponding commodity information is information of the source, the production date (picking date), the batch and the like of the agricultural product; when the commodity is an artwork, the corresponding information is information of the author, the age, a multi-dimensional photo of the artwork, a certificate of an authentication organization and the like of the artwork. In summary, different commodities store different commodity information according to actual demands, and the corresponding commodity information generally includes: the commodity quality, weight, source, production date, batch, authority identification result certificate, ownership, high-definition multi-dimensional photos of the commodity and other information.
Step 202: carrying out block chain processing on the commodity information to generate an NFT (network file table) unique to the corresponding commodity;
among them, in the blockchain, early pass certificates, such as bitcoin and ether house, have two main characteristics: firstly, the separation can be performed, and secondly, the mutual substitution and equivalent exchange can be performed, which is called as substitution general evidence (FT for short). In the process of trading commodities from an internet channel, due to the replaceability of commodities, tracing is difficult to complete (various tracing results may exist); meanwhile, after obtaining various tracing results, one-by-one screening is needed, and results corresponding to the commodities are selected, so that correct commodity information of the physical commodities stored in the block chain NFT is obtained, and the authenticity of the commodities can be identified by comparing parameters imported by the commodities (physical commodities) with the correct commodity information stored in the block chain NFT. Obviously, it is difficult to accurately distinguish the authenticity of the commodity in a short time. In the embodiment of the invention, Non-replaceable certificates (or Non-homogeneous certificates, NFTs for short) are preferably adopted to be associated with the commodities, so that fast and accurate tracing is realized, commodity information stored on the block chain platform can be fast found, and the authenticity of the commodities is judged by comparison. Compared with FT, the irreplaceable general evidence has two characteristics: first, there are no alternatives, each being unique; second, it is not detachable. Based on the two points, the commodity can be traced after being associated with the NFT, and the tracing result is unique, so that the authenticity of the commodity can be accurately and quickly identified. The result of the blockchain process of the embodiment of the present invention is a process of converting a commodity into an NFT, and the NFT converted by the present invention can be understood as a "digital twin" virtual commodity, and each commodity has only a unique NFT corresponding to it, and the ID represents an identity tag of the virtual commodity, and each virtual product (NFT) corresponds to a unique ID (similar to an identity card corresponding to each resident).
Step 203: associating the commodity with the ID of the commodity NFT, and configuring a unique initial key for the NFT;
for the purposes of the present invention, after the buyer purchases the product from the merchant, the merchant will give the product and some information (including the ID) about the product to the buyer. The buyer needs to obtain the commodity information stored on the blockchain platform through some information about the commodity provided by the merchant, and then compare the imported parameters of the commodity with the commodity information on the blockchain platform to distinguish the authenticity. The embodiment of the invention relates the ID of the commodity and the ID of the commodity NFT, wherein the relating modes are various, the ID can be recorded on the commodity, the NFT certificate can be made, and the ID hangtag containing the commodity NFT can be made. Because the ID corresponding to each commodity is unique, no matter how many times the commodity is traded, the ID of the commodity does not change all the time in the trading process, and in addition to the initial password of the physical commodity and the corresponding NFT, the buyer can also obtain the ID associated with the physical commodity in the trading process. The commodity information stored on the block chain platform can be inquired through the ID, and the authenticity of the commodity is preliminarily judged by comparing whether the imported parameters of the commodity are completely the same as the inquired commodity information. However, each buyer and each merchant know the ID of the product, and the method of realizing the authorization of the product by the ID of the product is obviously not feasible. The embodiment of the present invention preferably sets the initial key of NFT, and whose e-wallet binds the initial key of the article NFT, indicating who owns the article (when the article NFT is not bound to any e-wallet, who owns the initial key of the article NFT, indicating who owns the article). The initial key of each NFT is only clear to the buyer himself, and storage, transaction and authorization of the NFT of the goods can be completed through the buyer's own wallet on the blockchain platform and the initial key of the goods.
Step 204: binding the initial key of the NFT with an electronic wallet of a buyer to finish the right of commodity attribution;
the ID of the commodity NFT may query the information of the commodity on the blockchain platform, but each transactor knows the ID of the commodity NFT, and it is obviously not feasible to complete the method for realizing the right of the commodity through the ID of the NFT. The embodiment of the invention actually realizes the right of ownership of the NFT of the commodity by binding the initial key of the NFT with the electronic wallet of the buyer. After the NFT of the commodity completes the right confirmation, the NFT corresponding to the commodity is stored in the electronic wallet of the buyer, and when the next transaction is performed, only a person who knows the account and the private key (which can be understood as the password of the electronic wallet) of the electronic wallet can complete the submission of the ownership right of the commodity. It is noted that, on the blockchain platform, the e-wallet will not be bound with the identity information of the buyer, and once the buyer loses or forgets the private key of the e-wallet, the corresponding NFT asset stored in the e-wallet will also be lost, that is, the NFT asset actually belongs to the e-wallet, and the process of the right-confirming is actually the process of binding with the e-wallet.
Step 205: in an application scenario, a merchant transacts commodities and initial keys of NFT to a buyer at the same time, the buyer judges whether a source of the commodities is legal or not by comparing whether parameters imported based on physical commodities are completely matched with commodity information stored on a block chain platform side or not and whether the initial keys provided by the merchant are the NFT initial keys corresponding to the commodities or not, and the authenticity of the commodities is judged through parameter comparison and the legality of the commodity source.
The real goods are usually identified by comparing the real goods with the standard real goods. The embodiment of the invention adopts the technical scheme that the comparison between the parameters of the physical commodity and the commodity information stored on the block chain platform is utilized, whether the initial key of the NFT of the commodity given by a merchant corresponds to the physical commodity is verified, the commodity and the NFT are transferred to the buyer simultaneously to determine the legality of a transaction channel of the merchant, and the authenticity of the commodity is distinguished through the channel and the comparison between the physical commodity and the commodity information.
According to the embodiment of the invention, the ID is set for the commodity NFT, the commodity is associated with the ID, and the commodity information stored on the block chain can be acquired through the ID of the NFT. After the transaction is completed, the merchant provides the physical commodity and the NFT initial key corresponding to the commodity for the buyer, and the buyer inquires the commodity information on the block chain platform through the associated ID on the commodity and then compares the commodity information with the imported parameters of the physical commodity to realize the primary identification of the authenticity of the commodity. Meanwhile, the initial key of the commodity NFT is bound with the buyer information, so that the right of the commodity is confirmed. In the transaction process, the merchant can easily realize the anti-counterfeiting and the right confirmation of the commodities only by providing the commodities to the buyer and the initial key of the NFT corresponding to the commodities. The buyer can judge the authenticity of the commodity by self by comparing the imported parameters of the physical commodity with the commodity information, and the initial key of the NFT can be bound with the buyer to realize the right confirmation, so that the anti-counterfeiting right confirmation efficiency of the physical commodity is greatly improved, and meanwhile, the labor cost is also reduced. It should be noted that both the ID and the initial key of the NFT can query the information of the commodity, except that the information queried by the ID is only the commodity information for comparison with the physical commodity, but all information provided by the commodity, such as the transaction record, the ID of the commodity, etc., can be queried by the initial key.
In order to present a complete version of the invention, further details of embodiments of the invention are provided below. Generating the ID of the commodity NFT, as shown in fig. 2, the specific steps include:
step 301: uploading commodity information metadata to a block chain platform;
in the embodiment of the present invention, the information of the commodity stored on the blockchain platform needs to be acquired through the ID of the commodity NFT provided by the merchant. The method comprises the steps that firstly, commodity information metadata are uploaded to a block chain platform, and when the commodity information metadata are searched subsequently, commodity information matched with a commodity can be inquired on the platform through an ID given by a merchant. It should be noted that since the product is associated with the ID of the product NFT, the buyer acquires the physical product and also acquires the ID of the product.
Step 302: the NFT is assigned a unique ID by an encryption algorithm.
After the commodity information metadata is stored in the blockchain platform, since there are many detailed information in the commodity information, it is troublesome for the merchant to directly provide the commodity information to the buyer. In the preferred embodiment of the present invention, the commodity information metadata is assigned with a unique ID for the NFT through an encryption algorithm, for example: the data is converted into a byte array through serialization, and the byte array is converted into the ID of the NFT through related algorithms such as Hash, wherein the Hash algorithm is only one of encryption algorithms. At this time, the ID of the NFT corresponding to each commodity is a character string, each character string after the encryption algorithm is unique, and correspondingly, the ID of the NFT corresponding to each commodity is also unique. In the embodiment of the invention, the ID of the commodity is once created, and no matter how many times the commodity is traded, the ID does not change.
Further, before the completion of the authorization of the commodity, the method further includes a step of binding the NFT of the commodity with the wallet of the buyer, as shown in fig. 3, specifically:
step 401: binding the NFT initial key with an electronic wallet of a buyer, and recording binding information of the NFT on a block chain platform;
after the merchant and the buyer complete the transaction, the merchant provides the buyer with the physical goods and the initial key of the goods, and the buyer can query the information of the goods on the blockchain platform through the ID associated with the goods and then compare the information to preliminarily distinguish the authenticity of the goods, but for the authenticity of the goods, the buyer's electronic wallet (personal electronic wallet address) needs to be bound. The embodiment of the invention preferably sets the electronic wallet for the merchant and the buyer, and in order to trace the source or channel of the commodity, the electronic wallet of the merchant binds the business license of the company or personal information (such as an identity card) represented by a legal person, and for the buyer, the personal information does not need to be bound. After the merchant binds the information, the system distributes an electronic wallet to the merchant; after the buyer registers on the blockchain platform, the system also distributes an electronic wallet to the buyer; the electronic wallet is actually an address of a storage asset allocated by the blockchain platform to each merchant or buyer, the NFT can be understood as a commodity, and the initial key of the NFT can be understood as a transaction right for opening the NFT, and the NFT can be transacted and transferred by possessing the corresponding initial key of the NFT. It is worth noting that the initial key of the NFT is bound with the buyer information, which is actually the process of binding the initial key of the NFT with the electronic wallet address owned by the buyer. After the binding is completed, the right of the commodity is confirmed (the right confirming process is actually the submission of the commodity ownership right), and the electronic wallet stores the NFT of the commodity. When the next transaction is made, the owner of the article is required to use the electronic wallet to perform the transaction, and the physical article is delivered to the next buyer or the recipient together with the ownership right of the article (NFT of the article).
Step 402: and after the binding is finished, recording the NFT in the electronic wallet of the buyer.
The binding process is also actually a process of determining the right, and after the binding is completed, the transaction is completed and the right is determined. The transaction is also recorded on the platform of the blockchain, and the commodities of the transaction also become private goods of the buyer of the transaction. In the blockchain technology, NFT transfer is performed by accounting, and after the NFT is bound to an e-wallet address, the NFT is recorded in the e-wallet address of the buyer by accounting.
Further, when the commodity is subjected to the second transaction, the commodity holder transfers the ownership right of the NFT of the commodity to the electronic wallet of the buyer to complete the confirmation right of the commodity, and the transfer of the ownership right of the NFT of the commodity has two ways, as shown in fig. 4, specifically:
step 501: when the electronic purse of the commodity holder is not bound with the initial key of the NFT to finish the authorization, the commodity holder provides the initial key to the buyer, and the authorization is finished by binding the electronic purse of the buyer with the initial key.
Step 502: when the electronic purse of the commodity holder is bound with the initial key of the NFT to complete the right, the commodity holder hands over the ownership right of the commodity to the buyer through the electronic purse of the commodity holder to complete the right confirmation.
In the embodiment of the invention, when the NFT is just generated by the physical commodity, the system allocates the initial key to the NFT of the commodity. When the physical commodity is transacted for the first time, the merchant provides the physical commodity and the corresponding initial key for the buyer. After acquiring the physical goods and the corresponding initial key, the buyer may or may not bind to its own electronic wallet using the initial key. When the next transaction is carried out, when the electronic wallet of the commodity holder is not bound with the initial key of the NFT to complete the authority, the commodity holder provides the initial key to the buyer, and the seller provides the physical commodity to the buyer through the binding of the electronic wallet of the buyer and the initial key to complete the authority; when the electronic wallet of the commodity holder is bound with the initial key of the NFT to complete the right, the commodity holder hands over the ownership right of the commodity to the buyer through the electronic wallet of the commodity holder, the right is completed, and the seller provides the physical commodity to the buyer.
After the transaction is completed, the merchant provides the transaction commodity and the NFT initial key corresponding to the commodity to the buyer, and the step of comparing the parameter imported based on the physical commodity with the commodity information stored on the blockchain platform side is specifically as shown in fig. 5:
step 601: a buyer acquires the ID of NFT associated with commodities through the commodities provided by a merchant;
step 602: and acquiring the commodity information stored on the blockchain platform through the ID of the commodity NFT.
After acquiring the ID of the commodity in the transaction from the merchant, the buyer can query the commodity information stored in the block chain platform through the ID, and then determine the authenticity of the commodity through the comparison between the imported parameters of the physical commodity and the commodity information.
Further, the authenticity of the commodity is determined by comparing whether the parameters imported based on the physical commodity are completely matched with the commodity information stored on the block chain platform side, as shown in fig. 6, specifically:
step 701: when the imported parameters of the physical commodity are completely consistent with the commodity information stored at the block chain platform side, and the initial key provided by the merchant is the NFT initial key quotient corresponding to the commodity, the source of the commodity is legal, and the commodity is judged to be a genuine product
Step 702: otherwise, the commodity is judged to be a fake product.
And judging that the commodity is a fake product as long as the imported parameters of the physical commodity provided by the merchant are inconsistent with the commodity information stored by the block chain platform or the initial key of the NFT delivered to the buyer by the merchant is not corresponding to the physical commodity. Fig. 7 is a schematic diagram illustrating the anti-counterfeit logic according to the embodiment of the present invention. The embodiment of the invention adopts two different information channels to check the accuracy of the information, and the commodity is proved to be a genuine commodity only if the information of the two channels is accurate at the same time (the parameters of the physical commodity are consistent with the commodity information through comparison and the source of the commodity is legal). It should be noted that, when the merchant conducts the transaction, the physical goods and the initial key of the NFT corresponding to the goods are always handed to the buyer. In addition, the anti-counterfeiting method based on the block chain NFT is realized on the premise of establishing the same block chain platform. When the commodity is traded on different platforms, especially under the condition that data among the platforms are not communicated, the anti-counterfeiting purpose of the embodiment of the invention can not be realized, for example: when the physical commodity of the buyer is stolen, the thief can directly apply for a merchant on other platforms and generate an initial password of the commodity, and because the data of different platforms are not intercommunicated, the original transaction platform of the commodity cannot call the data of the current transaction platform, and the thief is difficult to trace.
It should be noted that, when the commodity performs the first transaction, after the transaction between the buyer and the merchant is completed, the buyer receives the physical commodity and the initial key of the commodity NFT provided by the merchant, before the initial key of the NFT is bound to the electronic wallet of the buyer, the method further includes a step of confirming whether the initial key of the NFT provided by the merchant is the initial key of the NFT corresponding to the physical commodity by the buyer, and after the buyer confirms that the initial key of the NFT provided by the merchant is the initial key of the NFT corresponding to the physical commodity, the electronic wallet of the buyer can bind the initial key of the NFT provided by the merchant, as shown in fig. 8, the corresponding step of confirming specifically is:
801: querying the commodity information on a blockchain platform through a commodity NFT initial key provided by a merchant;
802: and comparing the commodity information with the commodity to further judge whether the NFT initial key provided by the merchant is the NFT initial key corresponding to the physical commodity.
As mentioned above, the commodity information queried by the NFT initial key includes, in addition to the commodity information compared with the physical commodity, all other information that can be provided, such as the ID of the NFT corresponding to the commodity, the transaction information of the commodity, and the like. After the commodity information is compared with the commodity, the initial key of the NFT provided by the merchant is determined to correspond to the initial key of the commodity, and then the initial key of the NFT can be bound with the electronic wallet of the buyer to complete the authentication of the commodity.
Example 2:
in order to better show the scheme, embodiment 2 of the present invention specifically explains the scheme by using a specific embodiment scenario, as shown in fig. 9, which shows a schematic diagram of a transaction process of a jeweler on a blockchain platform.
Step 901: the jeweler and buyer register on the blockchain platform, acquire respective e-wallet account and password, and save the registered e-wallet account information on the blockchain platform.
In order to realize the authorization of the goods, the initial key of the goods NFT needs to be bound with the electronic wallet of the buyer, and the authorization information needs to be recorded on the blockchain platform. In a specific embodiment, the block chain platform is needed to authenticate the merchant, register the information of the merchant and record the information on the block chain platform, so that the source of the commodity can be traced conveniently; for the buyer, only the e-wallet needs to be registered on the blockchain platform for normal transactions.
Step 902: and uploading the meta information of the commodity to a block chain platform by a jewelry dealer, generating the NFT of the commodity, and acquiring the ID and the initial key of the NFT.
After the merchant registers his electronic wallet on the blockchain platform, the merchant obtains the initial key of each commodity on the platform, and for the convenience of tracing the source of the commodity, the initial key of the commodity NFT and the information of the corresponding merchant are recorded on the blockchain platform in an associated manner. As mentioned above, the first transaction of the merchandise is actually the process of packaging the merchandise and the corresponding NFT initial key together. When the commodity is transacted for the first time, only the merchant knows the initial key of the commodity, and only the merchant can transact the commodity. It should be noted that after the completion of the authentication, the authentication information needs to be uploaded to the blockchain platform. For a commodity object, in order to identify the authenticity of the commodity more simply, the obtained ID of the NFT is associated with the commodity (for example, the ID is engraved on the commodity), the information of the commodity can be quickly inquired on a platform through the ID, and the authenticity of the commodity can be preliminarily identified through comparison.
Step 903: and the jeweller and the buyer carry out transaction, after the transaction is finished, the jeweller submits the commodity and the initial key of the NFT to the buyer, and the buyer identifies and authorizes the authenticity of the commodity.
In a specific embodiment of the present invention, the physical commodity is already associated with the ID of the NFT, and the buyer acquires the ID of the commodity NFT while acquiring the commodity. The buyer can obtain commodity information on the block chain platform through the ID, and then preliminarily judge the authenticity of the commodity through comparison (the authenticity of the commodity can be really realized only by transferring the NFT of the commodity through the secret key), and the right of the commodity can be confirmed by binding the obtained NFT initial secret key with the electronic wallet of the buyer. Besides, in order to improve the popularity and the transaction circulation of the jewelry goods, the query and the display of the goods NFT can be set by a blockchain platform dealer, and each buyer can select and query the items of the mood instrument on the platform by using the ID of the goods NFT and acquire a part of information of the items. After the transaction is completed and the buyer confirms the right of the commodity, the buyer can set the right by himself, can set which information to hide, can make public reference to which information, and can even hide the public key of the commodity, and does not disclose the commodity to the outside. When the buyer needs to carry out secondary sales, the platform also records the secondary sales behavior on the blockchain platform for tracing.
Example 3:
based on the specific implementation scenario of the jewelry trader in the embodiment 2, the embodiment of the invention further provides a further optimized business model, and the commodity maintenance service and the accurate marketing information are pushed to the user through the jewelry commodity backtracking user information.
After the buyer purchases the corresponding product from the jewelry store, the jewelry store assists the buyer to register the electronic wallet of the blockchain platform to finish the right to belong to the product. In order to prevent the buyer from being bored of the behavior that the jeweller requires the electronic wallet of the buyer registration platform, the jeweller can permanently enjoy the washing service of the commodity by committing the buyer, registering the account number of the block chain platform (the electronic wallet needs to be packaged into the account number of the block chain NFT in advance) and authorizing the commodity.
In jewelry goods, particularly gold, silver or diamond goods, the gloss of the goods is reduced by irregular maintenance. For those who love beauty and have a high pursuit of life, regular maintenance of jewelry goods is often performed. During maintenance, the buyer can deliver the goods to a jeweler for cleaning, leave the telephone number of the buyer to pick up the goods (not necessarily the telephone number of the goods owner), and trace back the electronic wallet of the user through the ID of the NFT recorded on the goods; the jeweler inputs the cleaning record into the platform and binds the cleaning record with the user electronic purse, and the corresponding cleaning record comprises a cleaning time node, the color and pollution condition of the commodity and the like. The cleaning frequency of the client to the commodity is inquired through platform analysis, logistics care services are pushed to an electronic wallet of a user through the cleaning frequency, a more appropriate cleaning time node can be analyzed according to the colored dirt condition of the commodity and the time for actively taking the commodity to a jewelry shop to clean by the client based on each time of commodity cleaning, and the client (buyer) is promoted to the good feeling of the jewelry business by pushing and cleaning the electronic wallet of the commodity owner through the platform. For example, each time a customer goes to a door for cleaning, the customer finds that the color and stain condition is serious, the platform can remind a jeweler that the customer (a commodity owner) should be informed of the cleaning of the commodity at a certain interval in advance, and for the jeweler with chain stores, the platform can also inform the position distribution of the chain stores in various places of the customer.
In addition, for chains of jewelry in different locations, the products in the jewelry chain of different locations may not be identical, perhaps because of local personal habits or preferences. When a customer washes the goods in a jewelry shop, the address of the goods washing is recorded, the electronic wallet information of the customer is inquired through the ID of the goods NFT recorded on the washed goods, and the goods of nearby chain stores are pushed to the electronic wallet corresponding to the customer, so that accurate marketing is realized. For example: customer A purchases a commodity a at a jewelry merchant originally when working in Wuhan, and since the work is transferred to Beijing and the commodity a is cleaned at the Beijing, the jewelry merchant can inquire the user information of the customer A through the ID on the commodity a and push the commodity of the jewelry merchant at the Beijing to the account number of the customer A so as to achieve the purpose of accurate marketing.
Example 4
In order to better explain the scheme, embodiment 4 of the present invention adopts a specific embodiment scenario and the scheme of the present invention is further explained. The embodiment of the invention mainly solves the problem of how to prevent property loss of the drawer caused by bill loss in the circulation process of the commercial draft or the bank draft.
In a specific scenario of this embodiment, it is assumed that the drawer has registered its own e-wallet on the blockchain platform and that a transaction of a ticket (or a change of ticket) needs to be conducted on this blockchain platform.
Each time a drawer issues a particular ticket, the ticket is converted to an NFT, and the blockchain platform assigns an initial key to the NFT.
When in transaction, the drawer delivers the bill and the NFT initial key corresponding to the bill to the payee or the donator (the drawer can also bind the initial key of the check NFT with the electronic wallet of the drawer, and then operates on the electronic wallet of the drawer in a transfer mode to complete the delivery of the bill NFT ownership right). The payee or the donator needs to bind the initial key corresponding to the bill NFT with the electronic wallet of the payee or the donator to finish the right confirmation of the ownership right of the bill, and then the acceptor needs to cash the bill through the electronic wallet transfer right confirmation operation. When the check issued by the drawer is lost or stolen carelessly, the drawer holding the bill does not have the initial key corresponding to the bill NFT, the submission of the ownership right of the bill cannot be completed, the asset corresponding to the bill cannot be extracted to the account of the drawer, and unnecessary loss of the drawer is avoided.
Example 5
Based on the explanation of the present solution in embodiment 1, this embodiment 5 further provides a specific application scenario: after the goods are stolen, the buyer can claim the stolen goods recovered by the police, thereby maintaining the rights and interests of the buyer.
When the physical goods purchased by the buyer are stolen, two situations exist: first, the electronic wallet of the buyer is not bound to the commodity (without authorization), and at this time, the thief does not have the initial key of NFT corresponding to the physical commodity and cannot perform transaction on the platform; second, the buyer has completed the authenticity of the commodity, and no matter whether the thief has the original key, the physical commodity cannot be legally traded. When the stolen goods are recovered by the police, the owner can claim the physical goods through the electronic wallet bound with the NFT initial key of the goods, and further the rights and interests of the buyer are maintained.
Example 6
Based on the explanation of the embodiment 1, the embodiment of the present invention further provides: after the gift is transferred, how to solve the problem that the recipient realizes the secondary transaction of the commodity under the condition that the authorization of the commodity is not completed.
In general, if a merchant does not inform a buyer that the attribution right of a commodity NFT needs to be submitted to a donor in a gifting process, and the donor can perform a secondary transaction of the commodity, the buyer can directly donate the physical commodity to the donor, and at this time, an electronic wallet of the donor is not bound to the commodity NFT, and the right confirmation is completed. When the donate carries out the secondary transaction, the platform queries the electronic wallet to which the commodity belongs through the ID of the commodity NFT, and pushes a message for confirming the ownership of the transferred commodity to the electronic wallet to which the commodity NFT belongs, and after the message is received, the transfer of the ownership of the commodity NFT can be realized through operation in the electronic wallet. Through message pushing and the transfer of the NFT ownership right of the commodity on the electronic wallet of the buyer, the problem that the second transaction of the commodity is realized when the gift receiver does not finish the right of the commodity is solved.
