Figure 1 shows an example of an NFT transaction system 100 according to an embodiment of the present disclosure. NFT (Non-fungible Token) is a concept created to make digital data an asset by giving it uniqueness. Specifically, if a unique code is assigned to any digital data, and the transaction details for the digital data are encrypted along with the assigned code and configured to be permanently stored in the blockchain, such digital data can be referred to as NFT. there is. In the present disclosure, the above-mentioned ‘digital data’ may be referred to as an ‘item’. In addition, in the present disclosure, creating and/or issuing an 'NFT' involves assigning a unique code to digital data (or item), encrypting the transaction details for the assigned code and digital data, and storing it in the blockchain. It can mean something. In this disclosure, an NFT transaction system 100 designed to allow individual users to easily sell and/or purchase such NFTs is disclosed. As shown, the NFT transaction system 100 may include at least one of an information processing system 110, a seller terminal 120, a buyer terminal 130, and an affiliate server 140.

The information processing system 110 may provide NFT transaction services. For example, the information processing system 110 creates and/or updates an algorithm designed for NFT transactions to install a program (e.g., It can be provided in the form of an application). In this case, the information processing system 110 can communicate with the seller terminal 120, the buyer terminal 130, and the affiliate server 140 through the corresponding program.

The information processing system 110 can generate NFT. Specifically, the information processing system 110 may assign a unique code to an arbitrary item, and store the code and the original owner information of the item in a blockchain previously formed in the information processing system 110. Afterwards, when a transaction for an NFT is performed and the owner of the NFT changes, the ownership transfer information of the NFT may also be encrypted and configured to be stored in the blockchain.

The information processing system 110 may store owner information related to the generated NFT. Specifically, the information processing system 110 may store ownership transfer information of NFT. Here, the ownership transfer information may include complete information associated with the original owner, previous owner, and current owner of the NFT. This ownership transfer information can give uniqueness to the NFT by being permanently recorded in the blockchain as described above.

The information processing system 110 may store user information associated with NFT transactions. Specifically, the information processing system 110 may store seller information of an NFT registered as a sale product and buyer information in progress of purchasing the NFT. The information processing system 110 generates a seller's unique key and a buyer's unique key based on such seller information and buyer information and uses them for NFT transactions, thereby ensuring the stability and security of the transaction.

The information processing system 110 can perform NFT transactions. Specifically, the information processing system 110 may receive a purchase request for NFT from the buyer terminal 130 and obtain the seller's account for the transaction. Then, the information processing system 110 can change the owner of the NFT from the seller to the buyer when the buyer's deposit to the acquired account is performed.

The information processing system 110 may communicate with at least one of the seller terminal 120, the buyer terminal 130, and the affiliate server 140 to obtain information and/or data required for NFT transactions. For example, the information processing system 110 may receive a request related to an NFT transaction from the seller terminal 120, and receive information and/or data from the affiliate server 140 in order to respond to the request. For another example, the information processing system 110 may receive a request related to an NFT transaction from the buyer terminal 130, and may receive information and/or data from the affiliate server 140 to respond to the request. . For another example, the information processing system 110 uses the seller terminal 120 and/or the buyer terminal 130 to enable a user (i.e., the seller and/or Buyer) can send a request for information input.

The seller terminal 120 and/or the buyer terminal 130 may transmit a request to the information processing system 110 to perform an NFT transaction. For example, the seller terminal 120 sends an item subject to NFT issuance (e.g., profile picture (PFP), digital art, digital real estate, game item, etc.) or information related to the item to the information processing system 110. By providing it, a request for selling the item can be transmitted to the information processing system 110. In this case, the item or information related to the item may be obtained through the affiliate server 140 (eg, digital art platform, digital real estate platform, game platform, etc.) where the information of the seller terminal 120 is stored. For another example, the buyer terminal 130 may transmit a request to transfer ownership of the corresponding NFT to the information processing system 110 by providing the information processing system 110 with the deposit details required for the NFT transaction. In this case, the deposit details can be obtained through the affiliate server 140 (eg, open banking server, securities company server, bank server, etc.) where the information of the seller terminal (!20) is stored.

Meanwhile, in Figure 1, the seller terminal 120 and the buyer terminal 130 are shown as a plurality of mobile phone terminals, but the present invention is not limited thereto. For example, the seller terminal 120 and/or the buyer terminal 130 may be installed on a program provided by the information processing system 110, such as a mobile phone terminal, a laptop, a desktop, or a wearable device. It may consist of one or more computing devices. Additionally, the affiliate server 140 may include a plurality of servers for each of different affiliates to perform each step of the NFT transaction.

Figure 2 is a schematic diagram of a private blockchain 210 and a public blockchain 220 according to an embodiment of the present disclosure. A private blockchain 210 for storing information and/data related to NFT may be formed on the information processing system for NFT transactions (e.g., information processing system 110) provided in this disclosure. The private blockchain 210 has no restrictions on the subject of reading permissions, transaction creation, and/or permission management (i.e., anyone can read, create transactions, and/or perform permission management). Additionally, the private blockchain 210 participates in a network connected to the blockchain, so transactions through the blockchain can be verified and/or approved. Additionally, the private blockchain 210 can use a proof-of-work (PoW) or proof-of-stake (PoS) algorithm that allows partial branching as a consensus algorithm. On the other hand, in the public blockchain 220, only authorized institutions (e.g., specific securities firms, banks, etc.) can have read permission, and only institutions with legal responsibility can create transactions. Additionally, in the case of a public blockchain 220, transactions can be verified and/or approved only through an authorized body and/or a supervisory authority. Lastly, the public blockchain 220 uses a BFT-based consensus algorithm that does not allow partial branches. According to the above, when the private blockchain 210 is used for NFT transactions, costs can be reduced, fast processing speeds can be realized, and only selected members can be encouraged to participate through verified procedures.

It can be configured.

Figure 4 is a block diagram showing the configuration of the processor 400 according to an embodiment of the present disclosure. Here, the processor 400 refers to a processor of an information processing system (eg, information processing systems 110 and 340). As shown, the processor may include at least one of a user information management module 410, a transaction processing module 420, and a transaction recording module 430.

The user information management module 410 may process user registration. That is, the user information management module 410 may receive user information from a user (i.e., seller and/or buyer) terminal, and compare the received user information with pre-stored data to approve or reject the user's subscription. . Meanwhile, if the user's subscription is approved, the user's user information may be stored in the user information management module 410.

The user information management module 410 may store seller information received from the seller terminal. The user information management module 410 may store buyer information received from the buyer terminal. Here, seller information and buyer information may refer to personal information (e.g., name, resident registration number, phone number, address, etc.) entered by the seller and buyer through the terminal, respectively.

The user information management module 410 may transmit the received seller information to the first affiliate server. For example, after receiving seller information, the user information management module 410 may transmit the seller information to the first affiliate server in response to completion of the seller's service subscription. Here, the first affiliate server may refer to the server of the platform associated with the item subject to issuance of the NFT. For example, a first affiliate server may refer to a server of a platform associated with PFP, digital art, digital real estate, or gaming.

The user information management module 410 may generate a unique seller key based on the received seller information. Then, the user information management module 410 may initially transmit the seller's unique key to the first affiliate server. In this case, the seller's unique key, which is primarily stored on the first affiliate's server, can be used to identify the seller in the process of performing an NFT transaction later. For example, when the information processing system transmits the seller's unique key along with a request (or information) to the first affiliate server, the first affiliate server compares the received seller's unique key with the previously stored seller's unique key and After identifying, you can respond to the request.

The user information management module 410 may transmit the received buyer information to the second affiliate server. For example, after receiving buyer information, the user information management module 410 may transmit the buyer information to the second affiliate server in response to receiving an NFT transaction request (or item purchase request) from the buyer terminal. Here, the second affiliate server may refer to the server of the organization that measures the credit rating of the user (here, the purchaser). Additionally, the second affiliate server may refer to the organization's server configured to determine whether the purchaser can purchase the selected item. In this case, the second affiliate server may be the same as or different from the first affiliate server.

The user information management module 410 may generate a unique buyer key based on the received buyer information. Then, the user information management module 410 may initially transmit the buyer's unique key to the second affiliate server. In this case, the buyer's unique key, which is primarily stored on the second affiliate server, can be used to identify the buyer in the process of performing an NFT transaction later. For example, when the information processing system transmits the buyer's unique key along with a request (or information) to the second affiliate server, the second affiliate server compares the received buyer's unique key with the previously stored buyer's unique key to purchase the buyer's unique key. After identifying, you can respond to the request.

The transaction processing module 420 may perform an NFT transaction using the seller's unique key and/or the buyer's unique key generated by the user information management module 410. First, the distance processing module 410 can create a seller's wallet based on seller information. Then, the transaction processing module 420 may store items associated with the seller information in the wallet created using the seller's unique key. Additionally, the transaction processing module 420 can generate NFTs for stored items. At this time, the item for which an NFT is issued may refer to an item selected based on user input received from the seller terminal. In other words, the item for which an NFT is issued may refer to an item selected by the seller for sale through an information processing system among a plurality of items stored in the wallet.

The transaction processing module 420 can process transactions for NFT. Specifically, the transaction processing module 420 may process a transaction for NFT using the seller's unique key and the buyer's unique key in response to receiving a transaction request for NFT from a buyer terminal associated with buyer information. More specifically, when receiving a transaction request for an NFT from a buyer terminal, the transaction processing module 420 may transmit information on the seller who is the current owner of the NFT and the seller's unique key corresponding thereto to the first affiliate server. In this case, the first affiliate server compares the seller unique key received from the user information management module 410 in advance with the seller unique key received from the transaction processing module 420, and if they match, can identify a specific seller. . Then, you can create an NFT real account for that seller. Additionally, if a real account already exists on the first affiliate server for the identified seller, the corresponding real account information can be transmitted to the transaction processing module 420.

The transaction processing module 420 can create an NFT for each item stored in the wallet. For example, the transaction processing module 420 stores the item(s) associated with the seller information received from the first affiliate server in the wallet (i.e., when the item on the first affiliate server and the wallet are linked), An NFT can be issued for each stored item(s). For another example, the transaction processing module 420 may generate NFTs only for items selected according to user input received from the seller terminal among items stored in the wallet.

The transaction processing module 420 may determine whether the price of the item set by the seller is appropriate. Specifically, the transaction processing module 420 may receive sales price information for an item (or NFT) from the seller terminal. Transaction processing module 420 may then determine the validity of the received sales price information. Specifically, the transaction processing module 420 calculates the asset value level of the item in response to receiving sales price information, and sells the item based on whether the calculated asset value level corresponds to the sales price information. It can be converted to a possible state.

The transaction processing module 420 may determine whether the buyer who selected the item can purchase the item. Specifically, the transaction processing module 420 may obtain a purchaseability determination result of the buyer through a third affiliate in response to receiving a transaction request for an item from the buyer terminal. Then, the transaction processing module 420 may continue the NFT transaction procedure based on the purchase possibility determination result received from the third affiliate server. That is, when the transaction processing module 420 determines that it is possible for the buyer to purchase an NFT based on the purchase possibility determination result received from the third affiliate server, it creates a virtual account based on the seller's real account that has already been created, The NFT transaction process can be continued by transmitting the corresponding virtual account information to the buyer's terminal. With this configuration, it is possible to prevent a situation where the ownership of an NFT is changed to the buyer in a situation where the buyer is not permitted to purchase the item based on laws and/or contracts associated with NFT transactions. In particular, the NFT's ownership transfer information is permanently stored on the blockchain, and uniqueness is given to the NFT based on the stored ownership transfer information, so transaction stability can be guaranteed through the process of determining the possibility of purchase in advance.

The transaction recording module 430 may record all information and/or data updated through NFT transactions processed by the transaction processing module 420. In particular, the NFT ownership transfer information changed by the transaction processed by the transaction record module 430 can be stored. Hereinafter, in FIGS. 5 to 10, specific embodiments of the operations of the above-described information processing system, seller terminal, buyer terminal, and affiliate server are described below.

Figure 5 is a flowchart showing a process for a seller to sign up according to an embodiment of the present disclosure. As shown, the seller terminal 510, the information processing system 520, and the first affiliate server 530 may participate in the seller's registration process. First, the seller terminal 510 may transmit seller information to the information processing system 520 (S512). Then, the information processing system 520 may approve (or reject) the seller's subscription based on the received seller information (S514).

If the subscription is approved, the seller terminal 510 may transmit an affiliate information linking request to the information processing system 520 (S516). Accordingly, the information processing system 520 may transmit the seller information and the seller's unique key to the first affiliate server (S518). Here, the first affiliate may refer to an institution that creates an account used for NFT transactions. The first affiliate server 530 can check whether the seller has signed up using the received seller information and/or the seller's unique key (S522). For example, the first affiliate server 530 may check whether the seller has registered based on whether there is seller information that at least partially matches the received seller information. If it is determined that the seller has already signed up, the first affiliate server can store the seller information and seller unique key (S524) to be used for future NFT transactions. On the other hand, if it is determined that the seller has not signed up, the first affiliate server may transmit an affiliate signup request to the seller terminal 510.

Meanwhile, the seller's sign-up process in Figure 5 can also be applied when signing up for another affiliate server. That is, the first affiliate server 530 in FIG. 5 may be replaced by a second affiliate server and/or a third affiliate server.

Figure 6 is a flowchart showing the process of creating a seller's real account according to an embodiment of the present disclosure. As shown, the seller terminal 610, the information processing system 620, and the second affiliate server 630 may participate in the process of creating the seller's real account. First, the information processing system 620 may transmit a request for approval to link the first seller information to the second affiliate (S612). In response to the received request, the seller terminal 610 may transmit an approval response for linking the first seller information to the second affiliate (S614).

In response to receiving the approval response, the information processing system 620 may transmit an account creation request including the seller's unique key (S616). Meanwhile, according to the method disclosed in FIG. 5, seller information and/or seller unique key may be stored in advance in the second affiliate server 630. In this case, the second affiliate server 630 can create a real account for the seller when the seller's unique key included in the account creation request matches the seller's unique key stored in advance. Then, the second affiliate server 630 may transmit seller information and real account information to the information processing system 620 (S622).

The information processing system 620 can generate the seller's wallet and NFT (S624). More specifically, the information processing system 620 may create a seller's wallet and upload item(s) associated with seller information to the wallet. Here, item(s) related to seller information may mean digital data acquired by the seller through platforms related to PFP, digital art, digital real estate, game items, etc. Then, the information processing system 620 can generate (issue) an NFT for each item(s) uploaded (to the wallet). Alternatively, the information processing system 620 may generate an NFT for an item selected among the item(s) uploaded to the wallet based on the user input received from the seller terminal 610.

Meanwhile, the second affiliate server 630 in FIG. 6 may be the same as or different from the first affiliate server and/or the third affiliate server of the present disclosure. In other words, the platform related to items (digital assets) and the platform for account creation may exist as one integrated institution or as separate institutions.

Figure 7 is a flowchart showing the investment details linkage process according to an embodiment of the present disclosure. Here, linking investment details may mean uploading digital assets (or digital data) previously held by the seller through another server to the wallet created in the information processing system 720, as described above in FIG. 6. As shown, the seller terminal 710, the information processing system 720, and the first affiliate server 730 may participate in the investment details linking process. First, the seller terminal 710 may transmit a request to link investment details to the information processing system 720 (S712).

The information processing system 720 may transmit the seller's unique key to the first affiliate server 730 along with the received investment details linking request. In this case, the first affiliate server 730 records the seller's investment details based on the result of comparing the seller's unique key received from the information processing system 720 with the seller's unique key pre-stored through the process described above in FIG. You can query (S716). Then, the first affiliate server 730 may transmit the searched investment details to the information processing system 720 (S718).

The information processing system 720 may store the received investment details in the seller's wallet (S722). This corresponds to the wallet and NFT creation step (S624) in Figure 6. Then, the information processing system 720 may receive a request to set a product for sale and a sales amount from the seller terminal 710. Here, the product for sale may refer to a user input for selecting an item to be sold through the information processing system 720 among the seller's investment details (i.e., item(s)) stored in the wallet. Additionally, the sales price setting request may include information on the sales price of the selected item entered by the seller through the seller terminal 710.

The information processing system 720 may confirm the asset value of the product for sale in response to the request (S726). That is, the information processing system 720 can determine whether the sales price set by the seller is appropriate for the selected item. Specifically, the information processing system 720 may calculate the seller's asset value level based on at least one of the issuer of the NFT for the item, ownership transfer information, and the seller's previous transaction history. Then, if the calculated asset value level and the sales amount information received from the seller terminal 710 correspond (that is, if the asset value level and the amount set by the seller are not within the error range), the corresponding item (and /or NFT for the item) can be registered as a sale product on the information processing system 720 (S732). On the other hand, if the calculated asset value level and the sales amount information received from the seller terminal 710 do not correspond (i.e., if the asset value level and the amount set by the seller are not within the error range), the A request to reset the sales amount may be transmitted to the seller terminal 710 (S728).

Meanwhile, in FIG. 7, the information processing system 720 is shown as checking the asset value of a directly sold product, but the present invention is not limited to this. For example, the information processing system 720 may transmit the sales amount information received from the seller to the server of an institution that evaluates the value of NFTs, and receive the asset value confirmation result from the institution's server.

Figure 8 is a flowchart showing a purchaseability evaluation process according to an embodiment of the present disclosure. Here, purchase possibility refers to the possibility of purchasing an NFT, which is determined based on information related to at least one of the buyer's previous purchase history, previous sales history, credit rating, and funding source when the buyer wishes to purchase a specific NFT. It's data. First, the buyer terminal 810 may transmit a product purchase request for a purchase target item among the item(s) stored in the seller's wallet to the information processing system 820 (S812).

The information processing system 820 may transmit a purchase possibility evaluation request (S814) to the third affiliate server 830 in response to receiving a product purchase request from the buyer terminal. Here, a third affiliate may refer to an organization that manages laws and/or rules related to NFT. The third affiliate server 830 may determine the buyer's purchase possibility in response to the request (S816).

As described above, if it is determined that the NFT selected by the buyer can be purchased based on the buyer's previous purchase history, previous sales history, credit rating, and source of funds, the third-party affiliate server 830 approves the purchase of the product through the information processing system It can be sent to (820). On the other hand, if it is determined that the buyer cannot purchase the selected NFT, the third-party partner server transmits a product purchase refusal to the information processing system 820, and the information processing system 820 responds to the transaction procedure for the NFT can be terminated.

Meanwhile, in FIG. 8, the buyer's purchase possibility evaluation is shown as being performed by the third affiliate server 830, but the evaluation is not limited thereto. For example, the information processing system 820 may directly determine the possibility of purchase based on the buyer's previous purchase history, previous sales history, and the buyer's credit rating and funding source previously obtained from a financial institution server.

Figure 9 is a flowchart showing the process of transferring ownership of NFT according to an embodiment of the present disclosure. The process of transferring ownership may be performed after the processes disclosed in FIGS. 5 to 8 are completed. As shown, the information processing system 910, the first affiliate server 920, and the second affiliate server 930 may participate in the process of transferring ownership. First, the information processing system 910 may transmit a request for virtual account issuance to the first affiliate server 920 (S912). Here, the first affiliate server 920 may refer to the server of the organization that issued the real account.

In response to the request, the first affiliate server 920 may create a virtual account based on the seller's already created real account and transmit the created virtual account information to the information processing system 910. Here, the virtual account may refer to a temporary account that is used only during the transaction process of the target NFT.

The information processing system 910 may confirm a deposit including owner information from the created virtual account (S918) and transmit a transfer request to the second affiliate server 930. Here, the second affiliate server 930 may refer to a server of a platform related to PFP, digital art, digital real estate, or games subject to NFT issuance. The second affiliate server 930 may change the owner of the item in response to the transfer request (S924). Then, whether the transfer was successful can be transmitted to the information processing system 910. In this case, whether the transfer is successful may include NFT ownership transfer information.

The information processing system 910 may transmit the received transfer success status back to the first affiliate server 920. In this case, the first affiliate server 920 that issued the virtual account can transmit the details deposited in the virtual account to the seller's real account and retrieve the virtual account.

Figure 10 is a flowchart showing an example of an information processing method 1000 for NFT transaction according to an embodiment of the present disclosure. Method 1000 may be performed by an information processing system of the present disclosure. Meanwhile, the method 1000 starts with the step (S1010) of storing seller information and buyer information by a user information management module and generating a seller unique key based on the seller information and a buyer unique key based on the buyer information. It can be. Then, the information processing system creates a wallet based on the seller information by the transaction processing module (S1020), and stores items associated with the seller information in the wallet using the seller's unique key by the transaction processing module (S1030). .

The information processing system can create an NFT for the item in the wallet (S1040). In this case, the information processing system for NFT transactions is a transaction processing module that can transmit seller information and the seller's unique key to the first affiliate server associated with the item. Then, the information processing system responds to a request to link the investment details for the first affiliate received from the seller terminal associated with the seller information, and the user information management module uses the seller unique key to determine the investment associated with the seller information from the first affiliate server. You can receive history information and save it in your wallet. In this case, the investment detail information may include information about the item.

The information processing system may process a transaction for NFT using the seller's unique key and the buyer's unique key in response to receiving a transaction request for NFT from a buyer terminal associated with buyer information by the transaction processing module (S1050) . For example, the transaction processing module, in response to receiving sales price information of the NFT from the seller terminal, calculates the asset value level of the NFT based on the information about the NFT, and the calculated asset value level and sales price information are If applicable, NFT can be registered as a product for sale. In this case, the information processing system for NFT transactions can calculate the asset value level based on at least one of the issuer of the NFT, ownership transfer information, and previous transaction history. In addition, the transaction processing module calculates the discount rate of the NFT based on the asset value level and sales price information, and calculates the discount rate for the discount rate if a transaction request for the NFT is not received even when a predetermined institution has passed from the time the sale of the NFT was initiated. A request for approval to apply information and discount rate can be sent to the seller's terminal.

The information processing system for NFT transactions responds to the user information management module transmitting the seller information and the seller's unique key to the second affiliate server for account opening, and the second affiliate server obtains a real account associated with the seller information, The seller's unique key can be stored. Then, the information processing system for the NFT transaction is such that the transaction processing module transmits the seller's unique key to the second affiliate server in response to receiving the transaction request, and the second affiliate server transmits the seller's unique key received from the transaction processing module. Based on the result of comparing the seller's unique key pre-stored by the user information management module, a virtual account based on a real account can be created.

The user information management module transmits the buyer information and buyer unique key to the third-party server for evaluating the buyer's purchase possibility, and the transaction processing module transmits the buyer unique key and buyer information to the third-party server in response to receiving the transaction request. A purchase possibility evaluation request associated with the transaction is transmitted, and the third-party server determines the purchase possibility associated with the buyer information based on the result of comparing the buyer unique key received from the transaction processing module and the buyer unique key pre-stored by the user information management module. can be calculated and transmitted to the transaction processing module. In this case, the purchase possibility may be calculated based on at least one of previous purchase history, previous sales history, credit rating, and funding source associated with the buyer information.

The transaction processing module generates standardized data for the NFT in response to receiving the transaction request, and the purchaseability evaluation request may include standardized data generated from the NFT. In this case, the information processing system for NFT transactions is that the standardized data is divided into items for each type of NFT, NFT creator information, and the address where the NFT is stored, and the type of NFT is PFP based on the description of the original data of the NFT. It can be decided on either NFT, art-type NFT, digital real estate NFT, or game NFT. Finally, the information processing system can update information about items changed by NFT transactions (S1060).
