[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] FIG. 1 is a block diagram showing a trading system according to an embodiment of the present invention. In FIG. 1, a valuable resource management server 4 is configured to be capable of transmitting and receiving data via an electric communication line 3 between a user terminal 1 and a user terminal 2 used by a user.

[0013] (Valuables Management Server 4) The valuables management server 4 has a function of managing the evaluation points of valuables owned by users. The user terminal 1 and the user terminal 2 are used by users who have been assigned user IDs, and the evaluation points of valuables owned by the users and managed by the valuables management server 4 can be confirmed via the user terminals.

[0014] The valuables management server 4 is hardware that is owned and operated by an amusement facility equipped with gaming machines such as pachinko and pachislot machines, and includes a database for managing evaluation points.

[0015] In this embodiment, the valuables management server 4 may be in a form that manages the evaluation points of valuables using hardware owned only by a single amusement facility, or it may be in a form that manages the evaluation points of valuables using hardware owned and operated by multiple amusement facilities that support this system, for example, facilities across Japan or within a prefecture.

[0016] In the present invention, valuables refer to the number of pachinko balls or medals that a user has left over as a result of playing at a gaming facility such as pachinko or pachislot. In the present invention, the number of pachinko balls or medals that remain on hand can currently be indirectly converted into cash at the gaming facility and can be used as funds to purchase NFTs, so the number of pachinko balls and medals are referred to as valuables. This valuable resource is managed using a score evaluation card 40 shown in FIG.

[0017] For example, if a user plays at a pachinko game facility and has 5000 balls left, 5000 points will be displayed in the display field 41. When the number of medals and the number of pachinko balls are displayed as points, it is preferable to determine rules that define the relationship between the points and the medals and the number of pachinko balls in advance and set the settings based on the rules. The display field 44 is a field for entering a user ID, and it is preferable to assign a unique ID such as "AB001." In this way, a correspondence is formed between the number of purchases required to purchase NFTs and the user ID (display field 44).

[0018] In this way, the valuable resource management server 4 can manage the number of purchases owned by the user using the evaluation card 40 that links the user ID with the number of purchases owned by the user.

[0019] The evaluation card 40 is provided with a column for identifying the user, and preferably includes, for example, a column 45 for identifying the user's address and a display column 46 for identifying the user's name. It is also preferable to include a display column 47 for identifying photo data.

[0020] The evaluation card 40 may be displayed by installing an application on the user terminal, or may be displayed on a browser or the like.

[0021] The application installed in the user terminal and displaying the evaluation card 40 may further be provided with a column for displaying the number of balls used in the gaming machine, such as saved balls, balls held on the day, etc. For example, in the evaluation card 40 shown in Fig. 2, the number of balls may be displayed below the display column 41 for the evaluation score. In this case, the valuables management server 4 also records the saved balls, balls held on the day, etc. in correspondence with the user, and these are displayed in the form of the evaluation card 40.

[0022] The application on the user terminal may be configured to display, in addition to a display field 41 for the evaluation points to be used in NFT transactions as shown in this system, a display field 42 for the number of pachinko balls owned by the user that can be used in gaming machines, and a display field 43 for the number of medals for slot machines.

[0023] In this case, the number of pachinko balls display column 42 can display the number of saved balls and the number of balls held for the day separately. Also, the number of medals display column 43 can display the number of saved medals and the number of medals for the day separately.

[0024] This allows the user to accurately grasp, via the terminal, the number of pachinko balls and medals that he or she owns and that can be used in the gaming facility.

[0025] The application installed in the user terminal can use the pachinko balls owned by the user in the gaming machine, or the number of medals owned by the user in the slot machine. The application installed in the user terminal and mediated by the user terminal can act as an interface with the pachinko machine and the slot machine.

[0026] It is preferable that the system be constructed so that users of the system can obtain NFTs as prizes for games at gaming facilities via their user terminals.

[0027] NFTs function as certificates and authenticity for digital assets such as digital art (such as paintings), game items, trading cards, digital photographs, digital audio, and digital text.

[0028] (NFT Server 5) The NFT server 5 is configured to be connectable to the NFT market server 6, and in this system, it is preferable that a mechanism be constructed in which the NFT server 5 receives NFT market information from the NFT market server 6 at a predetermined timing.

[0029] The NFT server 5 has the function of being able to convert NFT purchase funds used to purchase NFTs handled by the NFT market into evaluation points of valuables handled by the valuables management server 4 and vice versa.

[0030] The NFT server 5 refers to the cryptocurrency rate handled by the NFT market, determines the conversion rate, and converts the cryptocurrency into the evaluation score of the NFT handled by the NFT market based on the conversion rate. For example, the conversion rate is preferably determined by taking into account the system usage fee of the NFT server 5 and the like in addition to the cryptocurrency rate handled by the NFT market. It is preferable to refer to the rate at the time of obtaining information from the NFT market for the cryptocurrency rate.

[0031] In other words, when providing information to a user terminal, the NFT server 5 is a server that provides NFT information to the user, and has the function of obtaining appropriate information from the NFT market, which is the distribution venue for the purchase and sale of NFTs, and providing it to the valuables management server 4.

[0032] In addition, when purchasing NFTs from a user terminal, the valuables management server 4 Based on a purchase request from a user's device, NFTs are purchased by spending from a wallet that has been created in advance on the NFT market.

[0033] The owner of the purchased NFT is changed and recorded on the blockchain 7 through an owner change process from the NFT market server 6.

[0034] The NFT server 5 links and records data regarding the purchased NFT with the user ID of the user terminal.

[0035] As a result, the holder of the NFT on the blockchain 7 is, for example, the purchasing manager of the NFT server 5, but the actual owner is the user ID linked to the user terminal.

[0036] The NFT server 5 may be hardware owned by one or more entertainment facility managers, or hardware owned by a person who arranges the products offered at the entertainment facility.

[0037] (NFT Market Server 6) The NFT market server 6 is a computer that makes up the NFT market, and the NFT market is built to perform functions such as creating wallets to hold funds for purchasing NFTs, providing NFT sales information, accepting requests to purchase NFTs, processing payments for NFTs, and managing information on NFT holders.

[0038] The NFTs handled by the NFT market server 6 are managed by their holders on the blockchain 7.

[0039] (Blockchain 7) The blockchain 7 records the provenance of the NFTs handled by the NFT server 5 and the NFT market server 6. This blockchain 7 certifies the owners of the NFTs handled by the NFT server 5 and the NFT market server 6.

[0040] Figure 3 is an NFT classification list that allows you to select the NFT you want to purchase. The NFT classification list represents the relationship between the purchase point rank, which represents the value of an NFT as a digital asset as a score, and the NFT classification list, and is an NFT classification list created based on the classification list creation function of the valuables management server 4.

[0041] The relationship between the price of an NFT on the NFT market and its evaluation score is determined by the NFT server 5 converting the crypto assets handled on the NFT market from the NFT market information it obtains from the NFT market server 6 into an evaluation score and providing it to the valuables management server 4.

[0042] The valuables management server 4 has the function of converting the NFT market information provided by the NFT server 5 into an NFT classification list and providing it to the user terminal. The purchase point ranks in the NFT classification list are divided into ranks, for example, the first rank is 1 to 10,000 points, the second rank is 10,001 to 20,000 points, and the third rank is 20,001 to 50,000 points, and are compared to the classification list.

[0043] For the first rank of 1-10,000 points, the paintings available for sale under Digital Art A will be displayed as A1, A2, A3, .... The photographs available for sale under Digital Photography B will be displayed as B1, B2, B3, .... The trading cards available for sale under Digital Card C will be displayed as C1, C2, C3, .... And the audio items available for sale under Digital Audio D will be displayed as D1, D2, D3, ....

[0044] In addition, for the second rank of 10,001 to 20,000 points, the paintings eligible for sale of Digital Art A will be 11 , A 22 , A 33 , . . . Also, the photo B that is the subject of sale will be displayed as B 11 , B 22 , B 33, . . . The trading cards that are the subject of the sale of digital card C are displayed as C 11 , C 22 , C 33 , . . . Furthermore, the audio that is the subject of sales of digital audio D is displayed as D 11 , D 22 , D 33 , it displays ···.

[0045] In this embodiment, each NFT is identified by an NFT code, and the purchase price is determined for each NFT according to the current trading status. The price is presented for each NFT. The method of assigning the code is not particularly limited.

[0046] The relationship and ranking between the number of purchases and the NFT classification list are not limited to those shown in Figure 3, and various forms can be adopted.

[0047] The NFT classification list allows users to see which rank of NFT (Figure 3) they can purchase based on their valuable item points.

[0048] Since you know the individual price of the NFT you want to purchase, you can see whether you can purchase it or not based on the NFT purchase rating listed on the evaluation card 40.

[0049] Next, we will explain how a user can purchase NFTs via a user terminal. Figure 4 shows the NFT purchase confirmation list. In the figure, the left-hand side columns are for confirming the first purchase request, and the right-hand side columns are for confirming the second purchase request.

[0050] The confirmation list includes a column 401 for entering the application date for purchasing the NFT, a column 402 for entering the NFT code to be purchased, and a column 403 for entering the fact that the purchase has been realized.

[0051] In the field 403 for entering the fact that the purchase and acquisition has been realized, if the purchase and acquisition has been realized, "Acquired" is entered, and if the purchase and acquisition has not yet been realized, "Purchase application in progress" is entered. At the beginning of the application, column 403, which is used to record the fact that the purchase and acquisition has been realized, states “Purchase application in progress,” but if the purchase is successful, the valuables management server 4 sends a message to the user terminal 1 indicating that the requested NFT has been purchased, and column 403 is left as is, while column 404 states “Acquired.”

[0052] When "Acquired" is entered in field 404, the NFT purchase by the user with ID "AB001" is completed.

[0053] Once you have completed your first NFT purchase in this way, you can then purchase your second NFT. You can also purchase multiple NFTs in the same way, such as a third, fourth, and so on.

[0054] In order for a user to purchase an NFT, they need funds to purchase it. In the case of user ID "AB001", the purchase funds of 5,000 points listed on the evaluation card 40 in FIG. 2 can be used for the purchase.

[0055] Using the user terminal 1, for example, an NFT “A” worth “1500 points” is transmitted to the valuables management server 4. 11 " Make a purchase request.

[0056] The valuables management server 4 transmits and receives data to and from the NFT server 5 via the telecommunications line 3, and makes a purchase request. The NFT server 5 transmits the NFT “A” to the NFT market server 6 via the telecommunications line 3. 11 " purchase process.

[0057] The NFT server 5 executes a payment process in conjunction with the NFT purchase process with the NFT market server 6. In the payment process, the NFT server 5 executes a payment process for the price corresponding to the transaction price of the NFT to be purchased.

[0058] In the NFT purchase process, the NFT server 5 11 The NFT market server 6 requests a change in the holder of the purchased NFT "A 11In response to a request from the holder of "A", the purchase target NFT "A" will be transferred to Blockchain 7 at the request of 11 A process is performed to change the holder of " to the name of the creator of the wallet held by NFT server 5.

[0059] This means that if this is your first transaction on the NFT Market Server 6, you will receive the NFT "A 11 The holder of the NFT "A 11 The owner of the NFT changes from the creator to the buyer. In this way, when the owner of an NFT changes on the blockchain7, a block is created each time, and the created blocks are linked together like a chain for management purposes.

[0060] The NFT server 5 obtains data related to the NFT to be purchased whose holder has been changed on the blockchain 7 from the NFT market server 6. The data related to the NFT to be purchased is data including metadata of the blockchain 7 related to the NFT to be purchased.

[0061] The metadata on the blockchain 7 for the NFT to be purchased includes information about the NFT to be purchased, such as an identifier, creation date and time, an owner address indicating the owner, and the object URL (original digital data).

[0062] The NFT server 5 records data about the NFT to be purchased whose owner has been changed on the blockchain 7 in association with the user ID that made the purchase request from the valuables management server 4, and transmits the data to the valuables management server 4 so that the NFT can be displayed via the NFT purchaser's user terminal.

[0063] This creates a correspondence between the actual NFT holder and the holder recorded on the blockchain7.

[0064] Based on FIG. 5, a sequence diagram showing an example of an NFT transaction screen display process on a user terminal according to this embodiment will be described.

[0065] The NFT server 5 obtains NFT market information (NFT market data) from the NFT market server 6.

[0066] Next, the trading price of NFTs in the NFT market data is converted from the cryptocurrency handled by the NFT market into the purchase points handled by the valuables management server 4 based on a preset conversion rate, and the point-converted NFT market data is transmitted to the valuables management server 4.

[0067] Next, the valuables management server 4 creates an NFT classification list based on the classification list creation function, and transmits the NFT classification list to the user terminal.

[0068] Next, when the user terminal 1 attempts to display the purchase screen, the valuables management server 4 causes the user terminal 1 to display a list of purchasable items from the classification list based on the number of points owned by the user. The user terminal may also display a list of items that cannot be purchased by operating the user terminal.

[0069] (Example of a transaction method) Based on FIG. 6, we will explain NFT purchase in the trading method according to this embodiment.

[0070] The user terminal that made the purchase request transitions to an NFT purchase screen. The valuables management server 4 selects and displays from a list of purchasable NFT categories on the NFT purchase screen of the user terminal, based on the user ID corresponding to the user terminal and the user, and the number of points held corresponding to the user ID. The user operates the user terminal and selects the NFT for sale they wish to purchase (the NFT to be purchased) from the displayed NFTs for sale.

[0071] Therefore, when a procedure such as replenishing points is performed on a user terminal, the valuables management server 4 can select and display from the classification list based on the points after the replenishing points have been taken into account. Also, when points are consumed, it is preferable to select and display from the classification list based on the points after consumption.

[0072] The user terminal 1 makes an NFT purchase request to the valuables management server 4 for the NFT to be purchased. Along with the purchase request, the user terminal 1 sends NFT purchase request data to the valuables management server 4. The data includes the user ID of the user who made the purchase request and the code number of the NFT to be purchased. The valuables management server 4 receives the NFT purchase request data sent from the user terminal 1.

[0073] The valuables management server 4 compares the trading price converted points of the NFT for sale (the NFT to be purchased) corresponding to the code number of the NFT to be purchased indicated in the NFT purchase request data received from the user terminal 1 with the remaining points (number of points owned) of the user making the purchase request, and confirms whether the number of points owned by the user making the purchase request is equal to or greater than the trading price converted points.

[0074] The transaction price conversion points for the sold NFT are obtained from the valuables management server 4. If, as a result of the confirmation, the number of points held by the user requesting the purchase is less than the number of points converted into the trading price of the NFT to be purchased, a response is sent to the user terminal 1 of the user requesting the purchase informing them that the purchase is not possible due to insufficient points.

[0075] The transaction price conversion points for the NFT to be purchased are determined from the converted price information based on the NFT market information of the NFT market server 6 provided by the NFT server 5.

[0076] For example, if the price of the NFT a user is trying to purchase is 1,000 points, the user's owned points are 5,000 points, so it can be confirmed that the number of points owned by the user requesting the purchase is equal to or greater than the number of points converted into the transaction price.

[0077] If the result of this confirmation is that the number of points held by the user making the purchase request is equal to or greater than the number of points converted into the trading price of the NFT to be purchased, the valuables management server 4 receives the request as an NFT purchase request since the NFT can be purchased by the user terminal 1.

[0078] The valuables management server 4 transmits NFT purchase request information to the NFT server 5 based on a purchase request from the user terminal that made the purchase request.

[0079] The NFT purchase request information includes the code number of the NFT to be purchased and the user ID of the user making the purchase request (purchase requester user ID).

[0080] When the NFT server 5 receives the NFT purchase request information from the valuable item management server 4, it executes the process of purchasing the NFT and settling the price with the NFT market server 6. It is preferable that the payment be processed by the administrator of the NFT server 5 using a wallet that has been created in advance in the NFT market server 6.

[0081] In the payment process, the NFT server 5 executes a payment process for the price corresponding to the transaction price (price of the cryptocurrency) of the NFT to be purchased. Specifically, the NFT server 5 executes a process of paying the price corresponding to the transaction price (price of the cryptocurrency) of the NFT to be purchased from a wallet created in the NFT market server 6 in which the cryptocurrency of the purchase manager is stored.

[0082] A wallet for the cryptocurrency of the purchasing manager is created in advance in the NFT market server 6. The NFT server 5 deposits the cryptocurrency in an amount corresponding to the transaction price (price of the cryptocurrency) of the NFT to be purchased into the wallet.

[0083] In the NFT purchase process, the NFT server 5 requests the NFT market server 6 to change the holder of the NFT to be purchased.

[0084] In this embodiment, the administrator of the NFT server 5 requests the change as the NFT holder. The holder of the NFT recorded on the blockchain is a person different from the purchase requesting user, and is, for example, the administrator of the NFT server 5.

[0085] The price corresponding to the transaction price (price of the crypto asset) of the NFT to be purchased can be set, for example, as the total amount of the transaction price (price of the crypto asset) of the NFT to be purchased plus fees such as transaction fees (amount of the crypto asset), thereby ensuring the profits of the administrator of the NFT server 5.

[0086] When the NFT server 5 completes the processing of the NFT purchase and payment, the NFT market server 6 executes a process to change the holder of the NFT to be purchased on the blockchain 7 in response to a request to change the holder of the NFT to the purchase manager.

[0087] This will change the owner of the NFT being purchased, which is managed on Blockchain 7.

[0088] After this change of owner, an address indicating the purchase manager (purchase manager address) is recorded as the owner address in the metadata of the blockchain 7 regarding the NFT to be purchased. The purchase manager address is registered in advance in the NFT market server 6.

[0089] The NFT server 5 obtains data (purchased NFT data) regarding the NFT to be purchased whose holder has been changed to a purchase manager on the blockchain 7 from the NFT market server 6.

[0090] Data regarding the acquired NFT (purchased NFT data) is recorded in correspondence with the user ID of the purchase requester received from the valuables management server 4.

[0091] The purchased NFT data is data that includes metadata on the blockchain 7 regarding the NFT to be purchased. The metadata records the purchase manager address as the owner address. Therefore, the purchased NFT data is data that proves that the owner of the NFT to be purchased is the purchase manager.

[0092] The NFT server 5 transmits NFT purchase notification information to the valuable item management server 4. The NFT purchase notification information is information in which data related to the NFT is associated with the purchase requester user ID. The valuable item management server 4 receives the NFT purchase notification information transmitted from the NFT server 5.

[0093] When the valuables management server 4 receives the NFT purchase notification information, it transmits a purchase completion report to the user terminal 1 of the purchase requesting user. The purchase completion report is information indicating that the purchase of the NFT to be purchased has been completed, and the valuables management server 4 stores data related to the NFT in a data area (not shown) managed for the user ID of the user terminal 1, thereby making it possible for the data related to the NFT to be displayed from the user terminal via an application, browser, etc. installed on the user terminal.

[0094] This completes the NFT purchase from the user terminal. [Explanation of symbols]
