BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration example of a trading system according to one embodiment. In FIG. 1, the information processing device 1 executes a transaction (point-NFT transaction) process related to points given to a user and NFT (non-fungible token). Types of point-NFT transaction processing include NFT purchase transaction processing and NFT point award transaction processing.

The NFT purchase transaction process is a process for purchasing an NFT associated with the user by consuming points owned by the user. The NFT point granting transaction processing is processing for granting points to the user based on the NFT associated with the user.

The information processing device 1 transmits and receives data to and from a terminal (user terminal) 7 used by a user via a communication line. The user can use the user terminal 7 to request the information processing device 1 regarding point-NFT transaction processing. Types of requests related to point-NFT transaction processing that a user can make include NFT purchase requests related to NFT purchase transaction processing and point redemption requests related to NFT point awarding transaction processing. The NFT purchase request is a request to purchase an NFT associated with the user by consuming points owned by the user. A point exchange request is a request to give points to the user based on the NFT associated with the user.

The information processing device 1 transmits and receives data to and from the point management device 2 via a communication line.

The point management device 2 manages the points owned by the user. The user is registered in the point management device 2 and assigned user identification information (user ID) for identifying the user. The point management device 2 manages the points given to each user.

For example, when a user purchases a product or uses a service, a predetermined number of points is added to the remaining number of points owned by the user (remaining number of points). Also, as for the points, for example, the number of consumption points set for the product for which the user has exchanged points is subtracted from the user's point balance. Also, with respect to the NFT associated with the user by the NFT purchase transaction processing, for example, the number of consumption points converted from the purchase price (amount of crypto assets) of the NFT is subtracted from the balance of points of the user. Also, the points are, for example, regarding the NFT associated with the user by the NFT purchase transaction processing, based on the NFT, the number of points given to the user by the NFT point grant transaction processing is the number of points remaining for the user. is added.

The point management device 2 transmits and receives data to and from the user terminal 7 via a communication line. The user can use the user terminal 7 to make a request to the point management device 2 to inquire about the remaining number of points or to exchange the points for a predetermined product or service other than NFT.

The information processing device 1 transmits and receives data to and from the NFT market 4 via a communication line. The NFT market 4 is a distribution place (NFT marketplace) for purchasing and selling NFTs.

In addition, the NFT market 4 performs the functions of the NFT marketplace such as presentation of NFT sales information, reception of NFT purchase requests and sale requests, NFT payment processing, management of NFT holder information, etc. may be realized by a computer (NFT Market server) executing a computer program (NFT Market software) for realizing Accordingly, NFT Market 4 may refer to an NFT Market server.

Holders of NFTs handled by the NFT market 4 are managed on the blockchain 5. Blockchain 5 records the history of NFTs handled by NFT market 4. This blockchain 5 proves the holder of the NFT handled by the NFT market 4.

The information processing device 1 executes NFT purchase transaction processing in response to an NFT purchase request from the user. In the NFT purchase transaction process, the information processing device 1 is the selling price of the NFT that the user wishes to purchase (NFT to be purchased) based on the number of remaining points held by the user who requested the NFT purchase request (purchase request source user). When the amount of crypto assets is sufficient, the NFT market 4 is requested to place a purchase order for the NFT to be purchased and to change the holder of the NFT to be purchased to a predetermined purchase manager.

More specifically, the information processing device 1 uses a point conversion rate, which is a predetermined conversion rate between the points managed by the point management device 2 and legal currency (for example, Japanese yen), and the NFT in the NFT market 4. The point balance of the purchase requesting user is converted into cryptographic assets using the cryptographic asset conversion rate, which is the conversion rate between the cryptographic assets used as the transaction settlement currency and the legal currency. The point conversion rate is set in advance by the administrator of the point management device 2, for example. The crypto-asset exchange rate changes with time in the crypto-asset market. Therefore, the information processing device 1 always acquires the latest crypto-asset conversion rate from a predetermined information providing server. When the amount of crypto assets converted from the point balance of the purchase requesting user is equal to or greater than the amount of crypto assets that is the selling price of the NFT to be purchased, the information processing device 1 sends the NFT to be purchased to the NFT market 4. and request that the holder of the NFT to be purchased be changed to a predetermined purchase manager.

The NFT market 4 changes the holder of the NFT to be purchased to the purchase manager to the blockchain 5 in response to the purchase order of the NFT to be purchased and the request to change the holder of the NFT to be purchased to the purchase manager. Execute the process. As a result, the holder of the purchase target NFT recorded on the blockchain 5 is changed to the purchase manager. The purchase manager is different from the purchase requesting user. A purchase manager is, for example, a manager who manages the point management device 2 .

The information processing device 1 acquires from the NFT market 4 NFT data related to the NFT to be purchased whose owner has been changed to the purchase manager on the blockchain 5 . NFT data is data related to NFTs and includes metadata on the blockchain 5 . Metadata on the blockchain 5 regarding the NFT has information such as the identifier, the date and time of creation, the owner address indicating the owner, and the target URL of the NFT. The object URL is a URL (Uniform Resource Locator) indicating the location of a digital asset (original digital data), which is an object for which the NFT certifies the owner. There are various digital assets, such as digital art, game items, trading cards, digital photographs, digital voices, and digital texts, for which NFTs prove ownership.

The information processing device 1 records, outside the blockchain 5 , NFT data relating to the NFT to be purchased whose owner has been changed to the purchase manager on the blockchain 5 .

The information processing device 1 executes a payment settlement process for paying the price corresponding to the purchase price of the NFT to be purchased in accordance with the purchase order of the NFT to be purchased to the NFT market 4 .

The information processing device 1 executes NFT point grant transaction processing in response to a point exchange request from the user. In the NFT point granting transaction process, the information processing device 1 determines that the NFT (NFT for sale) associated with the requesting user of the point exchange request (point exchange requesting user) is the exchange point specified by the point exchange requesting user. Place a sell order for the NFT to be sold to the NFT Market 4 if it can be exchanged for numbers.

More specifically, the information processing device 1 uses a point conversion rate, which is a predetermined conversion rate between the points managed by the point management device 2 and legal currency (for example, Japanese yen), and the NFT in the NFT market 4. Using the crypto-asset conversion rate, which is the conversion rate between the crypto-asset used as the transaction settlement currency and the legal currency, the number of exchange points specified by the point exchange requesting user is converted into crypto-asset. The point conversion rate is set in advance by the administrator of the point management device 2, for example. The crypto-asset exchange rate changes with time in the crypto-asset market. Therefore, the information processing device 1 always acquires the latest crypto-asset conversion rate from a predetermined information providing server. In the information processing device 1, the amount of crypto assets converted from the number of exchange points specified by the point exchange requesting user is equal to or less than the amount of crypto assets that is the selling price of the NFT related to the NFT to be sold in the NFT market 4 (related NFT). , a sell order for the NFT to be sold is issued to the NFT market 4, specifying the amount of crypto assets converted from the number of exchange points of the point exchange requesting user as the selling price. A related NFT of an NFT offered for sale is a separate NFT generated based on the underlying digital asset of the NFT offered for sale or a NFT created based on a digital asset related to the underlying digital asset of the NFT offered for sale.

When the sale transaction of the NFT to be sold is established, the NFT market 4 executes processing for changing the holder of the NFT to be sold to the owner of the sale destination on the blockchain 5 . As a result, the holder of the NFT to be sold managed on the blockchain 5 is changed from the original holder (purchase manager) to the holder of the sale destination.

The information processing device 1 executes payment settlement processing for receiving the price corresponding to the selling price of the NFT to be sold in accordance with the selling order of the NFT to be sold to the NFT market 4 .

When the sale of the NFT to be sold is successful, the information processing device 1 cancels the association between the NFT to be sold and the point exchange requesting user, and points converted from the amount of crypto assets, which is the selling price of the NFT to be sold. The number is notified to the point management device 2 as the number of points to be added to the remaining number of points of the user who requested the point exchange.

The information processing device 1 transmits and receives data to and from the NFT market 4 via a communication line. The information processing device 1 acquires transaction information (NFT market data) on NFTs from the NFT market 4 . The NFT market data includes information about the NFTs handled by the NFT market 4, such as identifiers, categories of objects, transaction prices (selling prices of crypto assets), transaction dates, and object URLs.

The information processing device 1 provides users with NFT market data acquired from the NFT market 4 . The user uses the user terminal 7 to acquire NFT market data from the information processing device 1 .

The user recognizes the category of the object (e.g., digital art, game item, trading card, etc.) and transaction price (selling price of crypto assets) for each NFT sold in NFT market 4 by NFT market data. be able to. As a result, the user can determine the value of the desired NFT from the transaction price (selling price of the crypto asset). Then, the user can decide the NFT that the user wishes to purchase (an NFT to be purchased) based on the result of the determination.
The information processing device 1 may convert the NFT transaction price (selling price of crypto assets) included in the NFT market data into points managed by the point management device 2, and then provide the NFT market data to the user. . This allows the user to recognize the trading price of the NFT in terms of points.

In addition, the user can use the user terminal 7 to access the object URL included in the NFT market data and confirm the NFT object (original digital data).

The information processing device 1 acquires the transaction information of the NFT (related NFT) related to the NFT from the NFT market 4 and provides the transaction information of the acquired related NFT to the user to whom the NFT is already associated. do. The related NFT transaction information is information including the latest transaction price (cryptocurrency selling price) and transaction date for the related NFT.

A related NFT (denoted NFT_B) of one NFT (denoted NFT_A) is, for example, a separate NFT generated based on the underlying digital asset of NFT_A. In this case, NFT_A and NFT_B are a group of NFTs generated based on the same digital asset.

A related NFT (denoted as NFT_B) of an NFT (denoted as NFT_A) is, for example, an NFT generated based on a separate digital asset b related to the underlying digital asset a of NFT_A. A separate digital asset b related to digital asset a is, for example, separate digital art b drawn by the artist who painted digital art a. Digital asset b related to digital asset a is, for example, a separate game item b that can be used in the same game as game item a. A digital asset b related to a digital asset a is, for example, a separate trading card b that has an image of an idol that appears on trading card a.

A user who is already associated with an NFT can use the transaction information of the related NFT as a reference for the transaction price (selling price of crypto assets) and demand on the NFT market 4 for the NFT associated with the user.
Note that the information processing device 1 converts the transaction price of the related NFT (selling price of the crypto asset) included in the transaction information of the related NFT into points managed by the point management device 2, and then provides NFT market data to the user. may This allows the user to recognize the transaction price of the related NFT in terms of points.

The information processing apparatus 1 may be implemented by a single computer, or may be implemented by distributing the functions of the information processing apparatus 1 to a plurality of computers. Further, the information processing apparatus 1 may be configured to open a website using, for example, the WWW system.

The storage unit 10 stores various data such as point exchange target management data 110 . FIG. 3 is a diagram showing a configuration example of point exchange target management data according to the present embodiment. In the example of FIG. 3, the point exchange target management data 110 is data in which a user ID and NFT data are associated with each user. In the point exchange target management data 110, the NFT data associated with the user (user ID) is associated with the user by consuming the points owned by the user to purchase the NFT corresponding to the NFT data. It is what was done. NFT data is obtained from NFT Market 4. In this embodiment, the NFT data in the point exchange object management data 110 corresponds to point exchange object data. Also, the user (user ID) in the point exchange target management data 110 corresponds to the person concerned in the NFT data.

Further, in the example of FIG. 3, the point exchange target management data 110 is data in which a specified value of the number of exchange points is further associated with the NFT data for each user. The specified value of the number of exchange points associated with the NFT data is a value specified by the user associated with the NFT data. Each user can arbitrarily designate a designated value for the number of exchange points.

The receiving unit 11 receives various kinds of predetermined requests from the user terminal 7 . A user can use the user terminal 7 to make various predetermined requests to the information processing apparatus 1 . For example, a user who possesses points managed by the point management device 2 can request the information processing device 1 to purchase a desired NFT (an NFT to be purchased). The accepting unit 11 accepts an NFT purchase request from the user terminal 7 . For example, a user associated with NFT data in the point exchange target management data 110 can make a point exchange request to the information processing device 1 to exchange the NFT data for points. The accepting unit 11 accepts a point exchange request from the user terminal 7 .

The transaction information acquisition unit 13 acquires NFT market data from the NFT market 4 . The transaction information acquisition unit 13 acquires the NFT data (NFT data for sale) associated with the point exchange requesting user in the point exchange target management data 110, and the association associated with the NFT for sale registered on the blockchain 5. NFT market data including the amount of crypto assets, which is the NFT selling price, is obtained from the NFT market 4 .

FIG. 4 is a diagram showing a configuration example of NFT market data (transaction information) according to the present embodiment. In the example of FIG. 4, for each NFT data associated with the user in the point exchange target management data 110, the NFT data of the related NFT (related NFT data), transaction information (latest selling price (cryptocurrency amount) and transaction date ) are included in the NFT market data.

The information processing device 1 provides users with NFT market data acquired from the NFT market 4 . The user uses the user terminal 7 to perceive the information contained in the NFT market data.

The crypto-asset exchange rate acquisition unit 14 acquires crypto-asset exchange rate information from a predetermined information providing server. The crypto-asset exchange rate information acquired by the crypto-asset exchange rate acquisition unit 14 from the information providing server is the exchange rate (crypto-asset exchange rate), which is information that includes the latest crypto asset conversion rate. Since the crypto-asset exchange rate changes from time to time in the crypto-asset market, the crypto-asset exchange rate information distributed by the information providing server is constantly updated. Therefore, the information processing device 1 constantly acquires information on the crypto-asset conversion rate from the information providing server.

In addition to the latest crypto-asset exchange rate, the information on the crypto-asset exchange rate that the crypto-asset exchange rate acquisition unit 14 acquires from the information providing server includes crypto-asset conversion It may also include rate fluctuation information, statistical values of crypto asset conversion rates for a certain period of time in the past, and the like.

The crypto-asset exchange rate acquisition unit 14 determines a crypto-asset exchange rate to be used by the conversion unit 15, which will be described later, based on the crypto-asset exchange rate information acquired from the information providing server. For example, the crypto-asset exchange rate acquisition unit 14 determines the latest crypto-asset exchange rate as the crypto-asset exchange rate used by the conversion unit 15 . For example, the crypto-asset exchange rate acquisition unit 14 obtains the crypto-asset used by the conversion unit 15 based on at least one of the latest crypto-asset exchange rate, the crypto-asset exchange rate fluctuation information, and the statistical value of the crypto-asset exchange rate. A conversion rate may be determined.

The conversion unit 15 performs conversion between points and crypto assets using the point conversion rate and the crypto asset conversion rate. The point conversion rate is a predetermined conversion rate between points managed by the point management device 2 and legal currency (for example, Japanese Yen). The point conversion rate used by the conversion unit 15 is set in advance by the administrator of the point management device 2, for example. The crypto-asset exchange rate used by the conversion unit 15 is the crypto-asset exchange rate determined by the crypto-asset exchange rate acquisition unit 14 .

Using the point conversion rate and the crypto-asset conversion rate, the conversion unit 15 converts the number of exchange points specified by the user requesting point exchange into the amount of crypto-asset. In addition, the conversion unit 15 converts the amount of crypto assets, which is the selling price of the NFT to be sold, into the number of points using the point conversion rate and the crypto asset conversion rate.

The point exchange control unit 16 executes point exchange control processing based on the point exchange request accepted by the accepting unit 11 . In the point exchange control process, the point exchange control unit 16 determines that the amount of crypto assets converted from the number of exchange points specified by the point exchange requesting user is the selling price of the related NFT related to the NFT to be sold in the NFT market 4. If it is equal to or less than the amount of the asset, a sell order for the NFT to be sold is issued to the NFT market 4 by designating the amount of crypto assets converted from the number of exchange points of the point exchange requesting user as the selling price. In addition, in the point exchange control process, when the sale of the NFT to be sold is established, the point exchange control unit 16 cancels the association between the NFT to be sold data and the point exchange requesting user in the point exchange object management data 110. , the number of points converted from the amount of crypto assets, which is the selling price of the NFT to be sold, is notified to the point management device 2 as the number of points to be added to the remaining number of points of the point exchange requesting user.

The point exchange control unit 16 executes payment settlement processing for receiving the price corresponding to the selling price of the NFT to be sold in accordance with the selling order of the NFT to be sold to the NFT market 4 . In NFT Market 4, a specific crypto asset is used as a settlement currency for buying and selling NFTs. Therefore, the point exchange control unit 16 executes processing for receiving the sale proceeds with the crypto assets used in the NFT market 4 .

The purchase management unit 31 manages NFTs purchased in the NFT market 4 . The purchase management unit 31 uses the purchase management table 33 to manage each NFT purchased in response to the NFT purchase request from the purchase request source user.

FIG. 5 is a diagram showing a configuration example of a purchase management table according to this embodiment. In the example of FIG. 5 , the purchase management table 33 stores the user ID, the purchased NFT data, and the identifier of the holder of the purchased NFT (NFT holder ID) for each user. The user ID is the user ID of the purchase requesting user. The purchased NFT data is NFT data related to the NFT to be purchased in response to the NFT purchase request from the purchase requesting user, and is acquired from the NFT market 4 . The NFT holder ID is the identifier of the holder of the purchase target NFT that has already been purchased. Therefore, the NFT holder ID is the identifier of the holder indicated by the holder address included in the purchased NFT data.

In this embodiment, the owner of the purchased NFT to be purchased is a predetermined purchase manager. The purchase manager is a person different from the purchase requesting user. Therefore, the NFT holder ID is the identifier of the purchase manager (purchase manager ID) and is different from the user ID. A purchase manager is, for example, a manager who manages the point management device 2 .

In this embodiment, the reason why the holder of the purchased NFT to be purchased is made the purchase manager is that, for example, in the NFT market 4, the purchase manager is collectively used as a purchase contact for settlement of NFT transactions. For example, by creating a crypto-asset wallet, there is no need to create a user-dedicated crypto-asset wallet for each user.

The purchase control unit 32 controls the purchase of NFTs.

The purchase control unit 32 executes NFT purchase processing of the NFT to be purchased with respect to the NFT market 4 in response to the NFT purchase request from the purchase request source user. The purchase control unit 32, in the NFT purchase process, when the amount of crypto assets converted from the point balance (the number of points for purchase) of the purchase requesting user is equal to or greater than the amount of crypto assets that is the selling price of the NFT to be purchased , to the NFT market 4, while placing a purchase order for the NFT to be purchased, requesting that the holder of the NFT to be purchased recorded on the blockchain 5 be changed to a predetermined purchase manager.

In the present embodiment, all of the remaining points of the purchase requesting user are used as the number of points for purchase, but the number of points for purchase may be equal to or less than the remaining number of points of the purchase requesting user. For example, the number of points for purchase may be limited to a predetermined percentage (for example, 90%) of the remaining number of points of the purchase requesting user.
Also, the number of purchase points may be designated by the purchase requesting user.

In addition, the purchase control unit 32 instructs the point management device 2 to secure at least the number of purchase points among the remaining points of the purchase requesting user for the purchase of the purchase target NFT until the purchase deadline of the purchase target NFT. may be requested. As a result, the remaining number of points of the purchase requesting user is used for purposes other than the purchase of the NFT to be purchased, and the purchase of the NFT to be purchased is executed in a state where points are insufficient for the purchase of the NFT to be purchased. can be prevented from occurring.
The purchase deadline for the NFT to be purchased may be specified by the purchase requesting user, or may be a certain period from the time when the purchase requesting user makes the NFT purchase request.

In addition, when the purchase requesting user makes a purchase request for the NFT to be purchased, the purchase control unit 32 sends at least the number of points for purchase out of the remaining points of the purchase requesting user to the point management device 2 for the NFT to be purchased. You may request that it be set aside for purchase.
In addition, when the purchase control unit 32 issues a purchase order for the purchase target NFT to the NFT market 4, the purchase requesting user confirms that the remaining number of points is equal to or greater than the number of points for purchase, and if the confirmation is obtained In addition to issuing the purchase order, the point management device 2 may be requested to secure at least the number of points for purchase among the remaining points of the purchase requesting user for the purchase of the NFT to be purchased.

The NFT market 4 changes the holder of the NFT to be purchased to the purchase manager to the blockchain 5 in response to the purchase order of the NFT to be purchased and the request to change the holder of the NFT to be purchased to the purchase manager. Execute the process. As a result, the holder of the purchase target NFT recorded on the blockchain 5 is changed to the purchase manager.

The purchase control unit 32 acquires from the NFT market 4 NFT data (purchased NFT data) relating to the NFT to be purchased whose owner has been changed to the purchase manager on the blockchain 5 . The purchase control unit 32 instructs the purchase management unit 31 to record the purchased NFT data acquired from the NFT market 4 . The purchase management unit 31 stores the purchased NFT data in the purchase management table 33 in association with the user ID of the purchase requesting user and the purchase manager ID as the NFT holder ID in accordance with the instruction from the purchase control unit 32 .

The purchase control unit 32 executes payment settlement processing for paying the price corresponding to the purchase price of the NFT to be purchased in accordance with the purchase order of the NFT to be purchased to the NFT market 4 . In NFT Market 4, a specific crypto asset is used as a settlement currency for buying and selling NFTs. Therefore, the purchase control unit 32 executes payment processing for the purchase price with crypto assets used in the NFT market 4 .

The purchase management unit 31 notifies the point management device 2 of the number of points converted from the amount of crypto assets, which is the purchase price of the NFT to be purchased, as the number of consumption points to be subtracted from the balance of points of the purchase requesting user. As a result, the point management device 2 causes the points of the purchase requesting user to be consumed by subtracting the number of consumption points from the remaining number of points of the purchase requesting user.

FIG. 6 is a block diagram showing a configuration example of the point management device according to this embodiment. In FIG. 6 , the point management device 2 includes a point management section 21 and a point control section 22 . The point management unit 21 has a point management table 23 .

FIG. 7 is a diagram showing a configuration example of a point management table according to this embodiment. In the example of FIG. 7, the point management table 23 stores the user ID and the remaining number of points (the remaining number of points owned by the user (holding points)) for each user.

The point control unit 22 controls points. The point control unit 22 instructs the point management unit 21 to award points. The point management unit 21 gives points according to the point giving instruction from the point control unit 22 . The point control unit 22 instructs the point management unit 21 to consume points. The point management unit 21 consumes points according to the point consumption instruction from the point control unit 22 .

For example, in response to the consumption point notification of the purchase requesting user from the information processing device 1, the point management device 2 subtracts the number of consumption points specified in the consumption point notification from the point balance of the purchase requesting user. By doing so, the points of the purchase requesting user are consumed. For example, the point management device 2, in response to the point exchange requesting user's given point notification from the information processing device 1, adds the point balance of the point exchange requesting user to the number of points to be given specified in the given point notification. is added to give points to the point exchange requesting user.

Next, an information processing method according to this embodiment will be described with reference to FIG. FIG. 8 is a sequence diagram showing an example of the procedure of the information processing method according to this embodiment.

(Step S11) The user (point exchange requesting user) uses the user terminal 7 to specify the NFT data to be exchanged for points (NFT data to be sold) and the number of exchange points to the information processing device 1, and A point exchange request is made to exchange the NFT data to be sold for points with the number of exchange points. The NFT data to be sold is NFT data associated with the point exchange requesting user in the point exchange object management data 110 . The user terminal 7 transmits point exchange request request data to the information processing device 1 in response to the user's point exchange request operation. The point exchange request request data is data including the user ID of the point exchange requesting user, the identifier of the NFT data to be sold (NFT data to be sold_ID), and the number of exchange points. The information processing device 1 receives the point exchange request request data transmitted from the user terminal 7 . In the information processing device 1 , the accepting unit 11 accepts a point exchange request based on the point exchange request request data received from the user terminal 7 . As for the number of redemption points, a specified value previously specified by the point redemption requesting user may be stored in the point redemption target management data 110 .

(Step S12) In the information processing device 1, the transaction information acquisition unit 13 acquires the NFT for sale corresponding to the NFT for sale (NFT_ID ) to the NFT Market 4 for the associated NFT's selling price.

(Step S13) In response to the inquiry about the selling price of the related NFT from the information processing device 1, the NFT market 4 acquires the selling price (cryptocurrency amount) of the related NFT from the registered information of the related NFT, It responds to the information processing device 1 with the selling price (amount of cryptocurrency). The NFT selling price (the amount of crypto assets) managed by the NFT market 4 is registered in the NFT market 4 by the NFT seller.

(Step S14) The crypto-asset conversion rate acquisition unit 14 in the information processing device 1 acquires crypto-asset exchange rate information from a predetermined information providing server. The crypto-asset exchange rate acquisition unit 14 determines the crypto-asset exchange rate to be used by the conversion unit 15 based on the acquired crypto-asset exchange rate information. The crypto-asset exchange rate acquisition unit 14 constantly acquires crypto-asset exchange rate information from the information providing server, and updates the crypto-asset exchange rate used by the conversion unit 15 based on the acquired crypto-asset exchange rate information. . Therefore, the crypto-asset exchange rate used by the conversion unit 15 is updated each time the crypto-asset exchange rate information distributed by the information providing server is updated in accordance with changes in the crypto-asset exchange rate on the crypto-asset market. . As a result, the crypto-asset conversion rate used by the conversion unit 15 accurately reflects the crypto-asset conversion rate that changes from time to time in the crypto-asset market.

(Step S15) In the information processing device 1, the conversion unit 15 uses the preset point conversion rate and the crypto-asset conversion rate determined by the crypto-asset conversion rate acquisition unit 14 to convert the point exchange requesting user into Convert the specified number of exchange points to the amount of crypto assets. Each time the crypto-asset exchange rate determined by the crypto-asset exchange rate acquisition unit 14 is updated, the conversion unit 15 uses the latest updated crypto-asset exchange rate to calculate the number of exchange points of the point exchange requesting user. Update the amount of crypto assets to be converted from. As a result, the crypto-asset amount converted from the number of exchange points of the point exchange requesting user accurately reflects the crypto-asset conversion rate that changes over time in the crypto-asset market.

(Step S<b>16 ) In the information processing device 1 , the point exchange control unit 16 determines a sell order for the NFT to be sold to the NFT market 4 with respect to the point exchange request from the point exchange requesting user accepted by the accepting unit 11 . The point exchange control unit 16, in determining the selling order of the NFT to be sold, determines that the amount of crypto assets converted from the number of exchange points of the point exchange requesting user is the selling price of the related NFT related to the NFT to be sold. Determine whether it is less than or equal to the amount. Each time the conversion unit 15 updates the amount of crypto assets converted from the number of exchange points of the point exchange requesting user, the point exchange control unit 16 updates the updated amount of crypto assets to the NFT to be sold. It is determined whether or not the selling price of the related NFT is less than or equal to the amount of crypto assets.

The point exchange control unit 16, when the amount of crypto assets converted from the number of exchange points of the point exchange requesting user is equal to or less than the amount of crypto assets that is the selling price of the related NFT related to the NFT to be sold, the NFT market 4 It is determined to place a sell order for the NFT to be sold to. After that, the process proceeds to step S17.

It should be noted that even if a predetermined waiting time for sale elapses after the accepting unit 11 accepts the point exchange request from the point exchange requesting user, the amount of crypto assets converted from the number of exchange points of the point exchange requesting user cannot be sold. If the selling price of the related NFT related to the target NFT does not fall below the crypto asset amount, the information processing device 1 notifies the user terminal 7 of the point exchange requesting user to that effect and sends a point exchange request. An inquiry may be made to the former user as to whether to continue or cancel the point exchange request for the NFT data to be sold. As a result of this inquiry, if the point exchange request for the NFT data to be sold is to be continued, the information processing device 1 (point exchange control unit 16) waits for the point exchange requesting user's It is determined whether or not the amount of crypto assets converted from the number of exchange points is equal to or less than the amount of crypto assets, which is the selling price of the related NFT related to the NFT to be sold. On the other hand, when canceling the point exchange request for NFT data to be sold, the procedure of FIG. 8 is terminated.

(Steps S17 and S18) The point exchange control unit 16 designates the amount of crypto assets converted from the number of exchange points of the point exchange requesting user as the selling price for the NFT market 4, and sells the NFT for sale (NFT_ID for sale). ) to place a sell order. When the sale transaction of the NFT to be sold is established, the NFT market 4 executes processing for changing the holder of the NFT to be sold to the owner of the sale destination on the blockchain 5 . As a result, the holder of the NFT to be sold managed on the blockchain 5 is changed from the original holder (purchase manager) to the holder of the sale destination.

When the sale transaction of the NFT to be sold is established in the NFT market 4, the point exchange control unit 16 executes payment settlement processing for receiving the sales proceeds corresponding to the selling price of the NFT to be sold. In NFT Market 4, a specific crypto asset is used as a settlement currency for buying and selling NFTs. Therefore, the point exchange control unit 16 executes processing for receiving the sale proceeds with the crypto assets used in the NFT market 4 .

(Step S<b>19 ) In the information processing device 1 , the purchase management unit 31 deletes the registration data regarding the NFT data to be sold from the purchase management table 33 when the NFT sale processing in steps S<b>17 and S<b>18 is completed.

(Step S<b>20 ) In the information processing device 1 , the point exchange control unit 16 cancels the association between the point exchange requesting user and the NFT data to be sold in the point exchange object management data 110 . For example, the point exchange control unit 16 deletes the registration data regarding the NFT data to be sold from the point exchange object management data 110 .

(Step S21) The conversion unit 15 in the information processing device 1 converts the amount of crypto assets, which is the selling price of the NFT to be sold, into the number of points using the point conversion rate and the crypto asset conversion rate.

(Step S22) In the information processing device 1, the point exchange control unit 16 sends the number of points converted from the amount of crypto assets, which is the selling price of the NFT to be sold, to the point exchange requesting user (user ID of the point exchange requesting user). is notified to the point management device 2 as the number of points to be added to the remaining number of points.

(Step S23) In the point management device 2, the point management unit 21, in response to the notification from the information processing device 1 of the number of points to be given to the point exchange requesting user (the user ID of the point exchange requesting user), The given number of points is added to the remaining number of points of the user (user ID of the user who requested the point exchange). The result of this point addition is recorded in the point management table 23 as the latest remaining number of points of the point exchange requesting user (user ID of the point exchange requesting user).

(Step S24) In the information processing device 1, the point exchange control unit 16 transmits an NFT sale report to the user terminal 7 of the user who made the point exchange request. The NFT sale report is information indicating that the sale of the NFT to be sold has been completed, and has information indicating that the number of awarded points exchanged from the NFT data to be sold has been awarded to the point exchange requesting user. The user can use the user terminal 7 to inquire of the point management device 2 about the remaining number of points and confirm the remaining number of points of the user himself/herself.

Note that in the above-described embodiment, the conversion unit 15 converts between points and crypto-assets using legal currency, but may directly convert between points and crypto-assets. When points and crypto-assets are directly converted, the crypto-asset conversion rate acquisition unit 14 acquires a point-to-crypto-asset conversion rate, which is the conversion rate between points and crypto-assets, and the conversion unit 15 converts points to crypto-assets. Use asset conversion rates to convert between points and crypto assets.

As described above, according to the present embodiment, regarding NFTs that are traded using crypto assets as settlement currency, it is possible to give points to the user based on the NFT associated with the user.

As a result, for example, it is possible to improve the overall service quality in a system that utilizes points held by users. , promote sustainable industrialization, and contribute to the expansion of innovation.
