[0019] The platform system relating to the embodiments of this disclosure (hereinafter also referred to as "this embodiment") Regarding M1, please refer to the drawing for explanation.

[0020] <Platform System Description> Platform System 1 is a form of computer system relating to games. It is a system that issues and distributes value-added media and provides a platform for their distribution. The value medium related to the subject is defined (represented) by digital data, for example, non-f Non-Fungible Token (also known as NFT) ) may be defined by. In this embodiment, this value medium is a game medium, and the value medium This example illustrates how to define a game medium using an NFT that defines a body. However, This invention does not intend to limit the value medium or NFTs that define the value medium to those mentioned above.

[0021] Digital trading cards as defined by NFTs in this practical application (hereinafter simply referred to as " A "digital card" (also called a "card"), i.e., an NFT-enabled digital tray. Trading cards will also be referred to as "NFT trading cards" below. Furthermore, the following definition of game media will be used. These NFTs are also called "game media NFTs" or simply "NFTs."

[0022] "Game media" refers to elements related to games. Game media include, for example, digital media. Code, name of the character to be used as the player character, the player character is virtual This includes items (weapons, armor, tools, etc.) used within the game space.

[0023] Images associated with the game medium (value medium), such as when the game medium is a digital card. Also called a "media image." A media image is displayed, for example, as part of a digital card. Furthermore, media images represent, for example, at least part of a game that has progressed through the player's actions. The game image shows the scene, and the real-world information image shows the actual event in which the game took place. include.

[0024] In Platform System 1, as the primary distribution, Platform System 1 is operated Companies that operate games, game operators, or retailers may use NFTs such as NFT trading cards. It can be sold online. Below is the primary flow in platform system 1. The environment necessary to achieve this (for example, the operating environment such as hardware and software) is, It is also called the "first platform." In addition, platform system 1 is used for secondary distribution and The NFTs that have been sold can then be bought and sold through transactions between users. The environment for realizing secondary distribution in Form System 1 is called the "Second Platform". It is also said that.

[0025] In platform system 1, users can combine other game media to form the combined system. The state of the game medium can be changed. Also, in platform system 1, -Za can disassemble multiple combined game media. Below are multiple game media "Customization" refers to changing the state of a game medium by combining or disassembling parts. Also said.

[0026] The state of the game medium refers to, for example, the appearance of the game medium (image of the game medium), parameters , or audio, etc. Platform System 1 combines multiple game media. This allows you to change the image on the game media or output sound from the game media. It is possible.

[0027] The game according to this embodiment is, for example, a competitive game that progresses through the actions of multiple players. It is a game, a so-called esports game. However, the game according to this embodiment This is not meant to be the sole limiting factor.

[0028] As shown in Figure 1, the platform system 1 consists of a server device 2 and multiple users It consists of device 5. Platform system 1 consists of server device 2 and multiple users The service devices 5 are connected to each other via a communication network 6 so that they can communicate with one another.

[0029] Server device 2 is operated by the operator of platform system 1 (hereinafter referred to as "system operator"). It is an information processing device used by the operator (also called the "business operator"). Server device 2 is programmed with a predetermined program. By executing this, an e-commerce server for selling NFTs to users and NFTs between users will be created. This implements a function to manage transactions.

[0030] User device 5 is an information processing device used by the user. User device 5 is a smartphone It could be a general-purpose terminal device such as a computer or laptop, or a platform system. It may be a device dedicated to M1. User device 5 executes a predetermined program. And, it provides users with a UI for trading value media. A specified program is, for example, However, an application program dedicated to platform system 1 (hereinafter referred to as "Toreca") It may also be a web browser (also called a "pre-loader"), or a web browser that is commonly provided in information processing devices. It may also be the case that the user device 5 communicates with the server device via, for example, the communication network 6. 2. Receive the trading card app from the application store (specifically, download and (Install) The trading card app stores and manages NFTs owned by the user, for example. It may also include a wallet function.

[0031] In platform system 1, user identification information is used for user account authentication. Each user is assigned account information, including their password. The user information is collected from the user device 5 when logging in via the trading card app or web browser. The data is sent to device 2, where the account authentication process is performed. After account authentication, communication between server device 2 and user device 5 becomes possible. After logging in, user device 5 receives data necessary for NFT trading from server device 2. When received from device 2, the image and sound of the NFT trading card are displayed based on the user's operation. Output to the earpiece and speaker.

[0032] Now, referring to Figure 2, the state of the game medium in platform system 1 changes. Let me explain an example.

[0033] As shown in Figure 2, in platform system 1, the user configures an NFT trading card. Card C1 (labeled "Card NFT (Main Body)" in Figure 2) and card parts P, etc. Game media can be purchased from official shops operated by the game's operating company or other related parties. This official shop is one of the online shop services provided by the first platform. There are two.

[0034] In the first platform, the first NFT and card part P define card C1. For each defined second NFT, the first NFT and the second NFT are provided to the user, respectively. A consideration fee for the association (hereinafter also referred to as the "first purchase price") is set. The second NFT is It is a different type of NFT from the first NFT, and can be used in association with the first NFT, for example. It may be anything. The first purchase price is paid by the official shop to the game operator, etc., and to the consumer. The consideration paid by a user to purchase game media, i.e., the consideration in a B2C transaction. This is the price. Furthermore, the first purchase price is different from that of the first and second users, and is determined by the system. This is a payment made to the source of purchase (seller), such as the operator, game developer, or retailer. That is the case.

[0035] Specifically, in the first platform, the website (EC) provided by server device 2 For these game media displayed on the official shop screen of the website or trading card app: The user selects the item they wish to purchase and issues a purchase instruction (hereinafter also referred to as "purchase instruction"). In response to this purchase instruction, the system associates (assigns) the purchased game media to the user. When users purchase game media from this official shop, they must purchase games from the official shop. The first purchase price will be paid to the game operator and other parties that sell the media.

[0036] Card C1 is the base and main body of the NFT trading card. Card C1 is an NFT card even on its own. It is possible to construct an FT trading card. The data defining card C1 is an NFT. In other words, Card C1 is an NFT-enabled game medium. Card C1 is the first game medium. This is one aspect of the first NFT that defines the first game medium, and the NFT of card C1 is one aspect of the first NFT that defines the first game medium. That is the case.

[0037] Card part P is a component that makes up an NFT trading card. The definition of card part P is The data is also an NFT. In other words, card part P is also an NFT-enabled game medium. Card parts P are, for example, frames P1 that decorate the frame of an NFT trading card (in Figure 2, "Car (The term "D-frame" is used to indicate the autographs of professional esports players and other players displayed on NFT trading cards.) Sign part P2 (labeled "Player's Signature" in Figure 2), where professional esports players Sticker part P, which shows stickers of the team's logo or game characters. This includes items such as 3 (labeled "seal" in Figure 2). Sign part P2 and seal part TsP3 can be freely placed in various locations on the image of an NFT trading card. In other words, Cards P is a game medium that allows you to customize Card C1. Parts P is one form of the second game medium, and the NFT of card part P is the second game medium This is one form of the second NFT as defined.

[0038] In this example, the user accesses the first NFT of card C1, the second NFT of frame P1, and the Assume you have purchased the second NFT from Inparts P2.

[0039] In platform system 1, the user can access the first NFT of the purchased card C1. I then associated the second NFT of frame P1 and the second NFT of sign part P2. This allows the user to connect card C1 to frame P1. It can be decorated with the sign part P2 (so-called "decorating"). In other words, - The process involves combining card C1 with frame P1 and signature part P2. It is possible.

[0040] Specifically, first, the server device 2 receives a frame from the user to the first NFT of card C1. A request is made to associate the second NFT of P1. Server device 2 responds to this association request. Then, the second NFT of frame P1 is associated with the first NFT of card C1. Server device 2 Based on the frame P1 in which the NFTs are linked in this way, the state of card C1 is determined. One of the changes is to alter the appearance. That is, server device 2 changes the appearance based on frame P1. The image of C1 is changed to an image bordered by frame P1. Then, the user receives the card. A request is made to associate the second NFT of sign part P2 with the first NFT of C1. 2, in response to this association request, signs the first NFT of card C1 to the Nth part of part P2. Associate the FTs. Server device 2 is a sign-in agent for NFTs that are associated with each other in this way. Based on P2, the appearance of card C1 is further modified. This frame P1 and signature Card C1, whose appearance has been modified based on image P1, will be designated as customized card C1'. The ver device 2 is a customer that has decorated card C1 with frame P1 and signature part P2. An image of the customization card C1' is generated, and this image of the customization card C1' is used in the user device 5. Display it there.

[0041] In platform system 1, the user can access the customization card C1'. The appearance, which is decorated with Room P1 and Sign Part P2, can be further modified. For example, the user can remove the decoration from sign part P2 from customization card C1'. This is possible. Specifically, the server device 2 receives the first NFT of card C1 and a signature from the user. Request to unlink part P2 from the second NFT (hereinafter also referred to as "unlinking request"). In response to this release request, Server device 2 will process the first NFT and signature part P2 of card C1. The association with the second NFT is removed. Server device 2, in response to this removal, customizes The appearance of the card C1' is changed. That is, in response to this unlocking, server device 2 changes the appearance of the card. Customized card C, with signature part P2 removed from the image of Tamaizu card C1'. The image of 1'' is displayed on the user device 5. Note that this removed (deactivated) sign The second NFT of part P2 can be reassociated with the first NFT of card C1, or another card book. It can be associated with the body's first NFT.

[0042] According to the above configuration, platform system 1 allows the user to associate NFTs or By unlocking or otherwise modifying the NFT trading card itself, the condition of the card, such as the frame or signature parts, can be altered. It can be freely modified based on this. The value of NFT trading cards changes depending on their condition. Because this can happen, when changing the status of an NFT trading card, the user's value may increase. By being creative and innovative, and by exploring popular designs, one can find enjoyment in the process. Therefore, platform system 1 is an NFT-enabled game medium. It is possible to improve the appeal of changing one's physical condition.

[0043] Now, referring to Figure 3, an example of a user-to-user transaction in platform system 1 is shown. explain.

[0044] As shown in Figure 3, in platform system 1, as secondary distribution, the first user Selling cards purchased from the official shop or customized cards to a second user (reselling) ) can be done. In this example, the system operator acts as an intermediary for transactions between users. The second platform of platform system 1 is such a user-to-user NF To realize an NFT marketplace where e-commerce is possible.

[0045] On the second platform, the first user and the second user use a game medium defined by an NFT. The price paid for purchasing the body (hereinafter also referred to as the "second purchase price") is paid by the first user This is set between the user and the second user. The second purchase price is the price at which the NFT is purchased between the users (consumers). The consideration paid for doing so is the consideration for a C2C transaction. In other words, a central administrator such as a system operator or game operator unilaterally sets the value of an NFT. Rather, it can be set by agreement between the first user and the second user, thus enabling transactions. This allows for value propositioning that is tailored to the user.

[0046] In platform system 1, in such transactions between users, the intermediary of the transaction They can collect fees such as quantity fees and copyright fees for the cards they sell. These fees collected in transactions between users in Form System 1 are collectively referred to as "Collection It is also called a "fee." Regarding this fee, server device 2 will, for example, handle NFT trading cards. The price may be set based on the selling price of the trading object, such as NFTs. For example, server device 2 may set the price based on the selling price of the trading object. The amount to be collected is calculated by multiplying the selling price of the trading card by a predetermined multiplier (for example, 30%). You may set a fixed amount and collect it.

[0047] One way in which NFT trading cards are sold from the first user to the second user is, for example, (1) card book (2) Selling the body (labeled "raw NFT" in Figure 3) as is, (3) Selling cards, (4) Selling multiple cards together (bundle sale), (5) e-sports A set of cards featuring images from the top 4 matches of the tournament will be sold. A variety of configurations are possible.

[0048] In platform system 1, secondary distribution occurs, with the first user transferring the car to the second user. Selling the second NFT of Doparts P as a standalone product (transferring the second NFT to a second user) ) is restricted. For example, in platform system 1, the second of card part P The sale of NFTs themselves may be prohibited, or the sale of the second NFT of card part P may be prohibited. There may be an upper limit on the number of times (number of transfers). Sale of the second NFT of card part P. The upper limit on the number of times may differ for each type of card part P. Also, for example, The maximum number of times you can purchase Frame Parts P3 (for example, up to 3 times) is the same as the maximum number of times you can purchase Frame Parts P1. The limit (for example, up to 100 times) may be set to a smaller number.

[0049] For example, as in the example above, the fee to be collected is calculated by multiplying the selling price of the item being traded by a predetermined multiplier. When setting the amount, if you include the card part P as the transaction item, the card itself and custom parts The fees charged may be lower compared to customized cards. This allows for restricting the inclusion of individual card parts P in transactions, thus lowering the fees charged. It can prevent that from happening.

[0050] <Server configuration> Returning to Figure 1, let's continue the explanation. Below are the hardware and functional configurations of server device 2. I will explain about that.

[0051] Server device 2 has a network interface 21, a storage unit 22, and a control unit 23. The network interface 21 and the storage unit 22 are connected to the control unit 2 via the bus 29. It is electrically connected to 3.

[0052] The network interface 21 connects to the Internet and other communication networks such as LANs. Each user device 5 is connected to the device via cable 6.

[0053] The storage unit 22 stores programs and data in the main memory, auxiliary memory, or external memory. It is a device for storing data. The storage unit 22 is, for example, an HDD (Hard Disk Drive). ve), RAM (Random Access Memory), ROM (Read O It can be constructed using (only memory) and SSD (Solid State Drive), etc. The memory unit 22 contains various programs, including a part of the program according to this embodiment. In addition, various other data such as user DB221 and token DB222 are stored.

[0054] The program according to this embodiment can be stored on a storage medium. The storage medium containing it is a non-transitory computer-readable medium. (m) is also acceptable. The non-temporary storage medium is not particularly limited, but for example, a USB memory stick. Alternatively, a storage medium such as a CD-ROM may be used.

[0055] User DB221 contains user identification information for each user who plays the game. Card identification information (card number and serial number) that identifies the NFT you own, platform Balance of electronic value usable within Form System 1, attribute information indicating user attributes, etc. However, it is stored in a corresponding location. Hereafter, this information will be collectively referred to as "user information." Here, "electronic value" refers to, for example, digital currency (electronic money) or crypto assets (virtual). It may also be a currency.

[0056] Token DB222 contains the NFT numbers of NFTs circulating on platform system 1. Furthermore, for each serial number, parameters, release date (issue date), distributor (issuer), and total number The row number, current owner, transaction history, etc., are stored in a linked manner. Here, "NF The "T number" is a number that indicates the type of NFT. The "serial number" is a number that indicates the type of NFT. This is a unique number assigned to each NFT issued on the NFT network. In the case of a sold NFT, the token DB222 contains the NFT, i.e., the game medium. Each real number may have its own unique digital data associated with it and stored accordingly. NFTs include an electronic certificate that proves their authenticity and an electronic certificate that proves their current owner. The book may contain at least one of the electronic certificates, and it was sold to the user. At that time, this NFT is moved (transmitted) to user device 5 and deleted from trading card DB222. This is also acceptable. Hereafter, this information will be collectively referred to as "NFT information."

[0057] "Parameters" refer to, for example, the combat power, attack power, and defense power of game media such as NFT trading cards. , physical strength (HP), intelligence, skill level, skill type, rank, or rarity, etc. be.

[0058] The control unit 23 is composed of a microcomputer including a CPU and semiconductor memory, and Controlling the operation of device 2, that is, data calculation, processing and transfer, and program execution. It is a processing unit (for example, a processor) that is responsible for controlling other devices. The control unit 23 is By executing the program stored in the memory unit 22, the server device 2 It can implement a variety of functions.

[0059] The control unit 23 executes various programs to control the information processing means 231 and the matching means. 232, reception means 233, association means 234, modification means 235, and release means 236 It functions as such.

[0060] —Information Processing Methods— The information processing means 231 transmits and receives various data with each user device 5. The main data received by stage 231 includes requests for display information and various data in response to user operations. Requests (for example, requests for specific digital cards, requests for gacha draws, or requests to purchase digital cards) Examples include payment requests, user information, and NFT information (including the NFT itself). The main data transmitted by the information processing means 231 includes trading card apps, NFT information, etc. Examples include the following. In addition, the information processing means 231 can, for example, access a website or a trading card app. Display information may be generated to display NFT trading cards or the like on the user device 5.

[0061] -Verification means- The matching means 232 uses the user identification information received from the user device 5 to determine the user account Perform authentication of the unit.

[0062] -Method of Reception- The reception mechanism 233 receives various selections, instructions, or requests from the user. Means 233, for example, involves using the first NFT and second NFT sold at the official shop as the first user When the company makes a purchase, it accepts purchase instructions for the first and second NFTs from the first user. .

[0063] -First reception method- The reception means 233 may include a first reception means 2331. The first reception means 2331 is The first user requests to associate the first NFT with the second NFT. Step 2331 is, for example, a key that associates card C1 and card part P from the first user. The request is accepted. In other words, the first receiving means 2331 accepts the card C1 from the first user. We accept requests to combine card part P with it.

[0064] -Second reception method- The receiving means 233 may include a second receiving means 2332. The second receiving means 2332 is The system accepts requests from the second user to unlink the first NFT from the second NFT. In other words, the second receiving means 2332 receives the combined card C1 and card from the second user. We accept requests to disassemble part P.

[0065] -Means of association- The association means 234 responds to a user request received by the receiving means 233, This links the data to an NFT, or to NFTs themselves.

[0066] -First association means- The association means 234 includes a first association means 2341. 1 is a first NFT that defines the first game medium, and a second NFT that defines the second game medium. , are associated with the first user respectively. In other words, the first association means 2341 is The first NFT and the second NFT are assigned to the first user. The first association means 2341 is, for example Then, in response to a purchase instruction from the first user, a first NFT defines card C1, and card part The second NFT defining part P is associated with the first user. The means 2341, when making this association, uses the payment method specified by the first user (for example, bank The consideration for this association (such as withdrawals from the account or settlements using electronic value) You may perform a process to settle the payment of the purchase price.

[0067] The first association means 2341, for example, on the first platform, the first NFT Information indicating that each of the second NFTs is associated with the first user (hereinafter referred to as "associated information") The system may generate or obtain a "report" (also called a "report") and associate this information with the first user. Specifically, the first association means 2341 associates the user information of the first user with the assigned information. The data may be stored in the memory unit 22.

[0068] The first association means 2341, for example, on the first platform, the first NFT Conditional on the first purchase price of each of the first NFTs being paid to the purchaser, The NFT and the second NFT may be associated with the first user. With such a configuration, In subsequent transactions, users may be required to pay a fee when purchasing NFTs.

[0069] -Second association means- The association means 234 includes a second association means 2342. 2, in response to a request from the user received by the first receiving means 2331, the first NFT and the second The NFT is associated with the second association means 2342. Information indicating that it is linked (hereinafter also referred to as "customization information") is generated, and the 1st N At least the first game medium as defined by FT and the second game medium as defined by the second NFT The data is associated with one of the above and stored in the memory unit 22.

[0070] The second association means 2342, for example, without requiring payment of consideration, connects the first NFT with To establish an association with the second NFT, and to dissolve the association between the first NFT and the second NFT. It may be permitted to remove, or at least one of the following. The second association means 2342 is, for example, This involves associating the first NFT of card C1 with the second NFT of card part P. If you exchange it, you will need to combine card part P with card C1, and pay the price for that. It may be permitted without this. On the other hand, the second association means 2342 is, for example, the first of card C1 To unlink the 1st NFT from the 2nd NFT of card part P, in other words, It is permitted to disassemble C1 and card part P without requiring payment of any compensation. That's good too.

[0071] With this configuration, users can access the first NFT and without worrying about paying a fee. You can associate or unassociate a second NFT. For example, card C1 You can combine card part P with it, or separate the combined card C1 and card part P. Users are free to customize NFT trading cards without paying any compensation. This is possible. Therefore, associating the first NFT with the second NFT and unassociating them is possible. We can provide an easy-to-use, user-friendly platform system. Cut.

[0072] The second association means 2342, for example, on the second platform, the first user and Subject to the payment of the second purchase price agreed upon with the second user, the first NFT and For each of the first and second NFTs, the association with the first user will be removed, and the association with the second user will be re-established. It is also possible to do so. With this configuration, NFTs can be traded between users in the secondary market. A fee may be required for this.

[0073] The second association means 2342 is, for example, collected by the purchaser from the first purchase price. The collected fees are paid to the seller, and the first purchase price, after the collected fees have been deducted, is paid to the first user. On the condition that payment is made to the first user for each of the first and second NFTs, the first user The association with the first user may be removed and the second user may be associated with the first user. Because fees such as brokerage fees and copyright fees are deducted from the purchase price, between users It can be reliably collected in transactions.

[0074] -Third association means- The association means 234 includes a third association means 2343. 3. With respect to the first NFT and second NFT associated with the first user, the first user Unassociate with the first user and associate with the second user. In other words, a third association method. 2343 transfers the first NFT and the second NFT, respectively, from the first user to the second user. The third association means 2343 allows the second user to specify during the unassociation and association process. In order to settle the payment for this cancellation and association (transfer) using a predetermined payment method. You may perform the following process.

[0075] The third association means 2343 is, for example, the first NFT of card C1 owned by the first user. And for each of the second NFTs of frame part P1, from the first user to the second user If sold, these NFTs will be unassociated with the first user and these NFTs will be sold. Associate it with the second user. In other words, the third association means 2343 associates card C1 with the second user. The first NFT and the second NFT of frame part P1 are transmitted from the first user to the second user. Move it to Za.

[0076] The third association means 2343, for example, associates the first NFT and the second NFT. Provided that this condition is met, the first NFT and the second NFT may be associated with the second user together. The third association means 2343 is, for example, the first NFT of card C1 owned by the first user. And regarding the second NFT of frame part P1, these NFTs are associated with Under these conditions, these will be bundled together as customized card C1'' and given to the second user. You can associate them.

[0077] The third association means 2343, for example, associates the first NFT and the second NFT. If not, the first NFT is allowed to be associated with the second user on its own, while the second NFT The association of T with a second user on its own may be restricted. Third association means 2343 For example, the first NFT of card C1 owned by the first user and the second NFT of frame part P1. If the NFTs are not associated with each other, in other words, if these NFTs are separate and independent If this is the case, the first NFT of card C1 is to be associated with the second user on its own (transferred) Even if it allows (the act of doing so) and restricts the association of the second NFT of card part P on its own good.

[0078] According to the above configuration, the third association means 2343 constitutes an NFT trading card on its own. Compared to the first NFT of card C1, which can constitute an NFT trading card on its own... Certain trading restrictions can be applied to card parts P that cannot be obtained.

[0079] For example, as in the example above, the fee to be collected is calculated by multiplying the selling price of the item being traded by a predetermined multiplier. When setting the amount, if you include the card part P as the transaction item, the card itself and custom parts The fees charged may be lower compared to customized cards. Therefore, the third association means 2343 restricts the inclusion of card part P alone in the transaction object. This allows us to prevent the collected fees from becoming too low.

[0080] The third association means 2343, for example, on the second platform, the first NFT Information indicating that each of the second NFTs is associated with a second user (hereinafter referred to as "transaction information") It generates or retrieves (also called "report") and associates it with a second user. Transaction information can be rephrased as This information shows the transaction history between users for each NFT. Specifically, it is related to the third association. Step 2343 associates the user information and transaction information of the second user with the storage unit 22 and / or Alternatively, it may be stored in the user device 5. With this configuration, the latest owner of the NFT Transaction information for this NFT can be searched by tracing it back through a second user.

[0081] <Granted information, customization information, and transaction information> Here, with reference to Figure 4, we will explain an example of the assigned information, customization information, and transaction information. In this example, the grant information, customization, and transaction information are included in the NFT information. The NFT information uses the NFT number and serial number as a composite key to uniquely identify each NFT. Identify it as follows.

[0082] (1) As shown in the area enclosed by the dashed line frame in Figure 4, the first association means 2341 is For example, on the first platform, the first NFT (NFT number "c-1" and If the real number "001") is associated with the first user, the associated information will be added. You can associate the report (the tag "#granted" and the grant date and time "2021 / 3 / 1") with the first user. stomach.

[0083] (2) As shown in the dashed frame in Figure 4, the second association means 2342 is, for example For example, the first NFT of card C1 and the second NFT of frame P1 (NFT number "p-1") If you associate it with serial number "001", this customization will indicate the association. Even if you associate the information (the tag "#combined" and the date and time of the merger "2021 / 3 / 3") with the first user Good. Also, the release means 236 can, for example, release the association between the first NFT and the second NFT. If removed, the customization information indicating this removal (the tag "#decomposition" and the decomposition date and time "2021 / 4") will be displayed. You may associate " / 5") with the first user.

[0084] (3) As shown in the area enclosed by the dashed line frame in Figure 4, the third association means 2343 is For example, the first NFT of card C1 and the second NFT of signature part P2 (NFT number "p- The association between "2" and serial number "001") and the first user will be removed all at once. Transaction information indicating that it is associated with 2 users ("#transfer" tag and transfer date and time) is provided to the second user It may be associated with -za.

[0085] -Methods of modification- Returning to Figure 1, let's continue the explanation. The modification means 235 changes the state of the game medium. In other words, If so, the modification means 235 customizes the game medium (other games) according to the user's operation. (Combining or disassembling the media.)

[0086] -First modification method- The modification means 235 includes a first modification means 2351. The first modification means 2351 is a first N Based on the second game medium defined by the second NFT associated with the FT, the first game medium The state is changed. The first changing means 2351, for example, based on sign part P2, The appearance of card C1 is changed. In other words, the first modification means 2351 changes the appearance of card C1 as shown in Figure 2. Like Myzcard C1', the image of signature part P2 is superimposed (pasted) on top. Display the image of code C1 on user device 5.

[0087] -Second modification method- The modification means 235 includes a second modification means 2352. The second modification means 2352 will be described later. In response to the release by the release means 236, the state of the first game medium is changed. Step 2352 is, for example, the relationship between the first NFT of card C1 and the second NFT of card part P. The state of card C1 is changed in response to the removal of the attachment. In other words, the second modification means 235 Step 2 returns card C1 to its state before card part P was combined with it.

[0088] According to the above configuration, the second modification means 2352, at the destination second user, the first NF In response to the unassociation between T and the second NFT, the state of the first game medium can be changed. For example, the first NFT defines card C1 and the second NFT defines sign part P2. Upon removing the association with T, the signature part P2, which was attached to card C1, is disassembled. It is also possible to do so. In this way, the second modification means 2352 can unassociate the NFT. This allows you to change the state of the NFT trading card itself. I purchased the second NFT card part P from [source] and left it attached to the first NFT card C1. It is possible to remove it, and furthermore, to attach the removed second NFT card part P to another first NFT It can also be attached to the card itself. Therefore, the second modification means 2352 is NFT-enabled. The entertainment value can be improved when changing the state of the game medium.

[0089] -Cancellation method- The release means 236, in response to the release request received by the second receiving means 2332, releases the first NFT The association with the second NFT is broken. In other words, the deactivation means 236 breaks the association of card C1 By unlinking the first NFT from the second NFT of card part P, the combined card Disassemble card C1 and card part P. The release means 236 disassembles card C1 and card part P in this way. Part P can be disassembled.

[0090] <Platform System Operation Flow> Refer to Figures 5-6, in primary and secondary distribution in platform system 1 This is an example of the process flow and interaction between the transaction processing and the customization of the traded game media. I will explain.

[0091] Figure 5 shows the process from when the first user purchases the first NFT and the second NFT as primary trading, to the first This shows the processing flow and interactions involved in changing the state of the first game medium as defined by NFT. This is a diagram.

[0092] As shown in Figure 5, first, the first user device 5a receives a purchase instruction from the first user, A first NFT defining the first game medium, and a second NFT defining the second game medium, The system accepts requests to associate each of the first users (step st11). Then, the first User device 5a sends this request to server device 2 (step st12).

[0093] Next, the receiving means 233 of the server device 2 sends the first NFT and the second NFT to the first user. Each accepts a request to associate (step st13). Next, the first association means 2341 associates the first NFT and the second NFT with the first user, respectively (step s t14).

[0094] Next, the first association means 2341 of the server device 2 associates the first N with the first user. The FT and the second NFT are transmitted to the first user device 5a, respectively (step st15). When user device 5a receives the first NFT and the second NFT, it processes the game defined by each. Output images and audio from the media (step st16).

[0095] Next, the first user device 5a associates the first NFT and the second NFT with the first user. The request is accepted (step st17). Then, the first user device 5a accepts this request Send this to server device 2 (step st18).

[0096] Next, the first receiving means 2331 of the server device 2 associates the first NFT and the second NFT. The request is accepted (step st19). Then the second association means 2342 Associate the first NFT with the second NFT (step st20).

[0097] Next, the first modification means 2351 modifies the second NFT defined by the second NFT associated with the first NFT. The state of the first game medium is changed based on the game medium. In this example, the first modification means 2 Section 351 explains an example of changing the parameters of the first game medium based on the second game medium. To clarify, the first modification means 2351 performs a process to change the state of the first game medium. One of these is to generate change information to reflect changes in the parameters of the first game medium. (Step st21). Next, the first modification means 2351 changes the state of the first game medium. As one of the processes to make changes, the generated change information is sent to the first user device 5a ( (up st21). The first user device 5a reflects the received change information in the first NFT. Change the parameters of the first game medium and output the first game medium with the changed parameters. (Step st22).

[0098] Figure 6 shows the first and second NFTs, which were sold by the first user as secondary trading, to the second The process from when the user makes a purchase until the state of the first game medium, as defined by the first NFT, is changed. This is a sequence diagram showing the flow and interaction.

[0099] As shown in Figure 6, the first user device 5a receives the associated first NFT from the first user. And in order to sell the second NFT, to list these on the NFT marketplace Accept the request (hereinafter also referred to as the "listing request") (step st31). In this example, The listing request shall include the first and second NFTs to be listed. The first user device 5a then sends this listing request to the server device 2 (step st32). .

[0100] Next, the receiving means 233 of the server device 2 receives the listing requests for the first NFT and the second NFT. Accepted (step st33). The information processing means 231 of server device 2 processes this listing request. Based on this, the 1st NFT and 2nd NFT are listed on the NFT marketplace. The information processing means 231 generates display information to enable the following: The displayed information is transmitted to the first user device 5a and the second user device 5b respectively (step (st35). The first user device 5a and the second user device 5b each receive a display. Based on the information, the first and second NFTs are distributed via websites and trading card apps. Display the listing (step st36).

[0101] Next, the second user device 5b receives the displayed first NFT and second NFT from the second user. A request to associate these NFTs with a second user in order to purchase FTs from the first user. The request is accepted (step st37). Then, the second user device 5b sends this request to the server. Send to device 2 (step st38).

[0102] Next, the receiving means 233 of the server device 2 receives the first NFT and the second NFT from the second user. The system accepts a request to associate FT with the second user (step st39). Third association Means 2343 unassociate the first NFT and the second NFT with the first user. The third association means 2343, in response to this release, provides the first user device 5a with respect to the first In order to transfer the NFT and the second NFT to the second user, the first NFT and the second NFT The user requests the movement of (step st41). The first user device 5a responds to this request by Send the 1st NFT and the 2nd NFT to the server device 2 (step st42). 2 transmits the transmitted first NFT and second NFT to the second user device 5b (step (P st43). Furthermore, as another example of the transfer of the first and second NFTs, server device 2 However, it causes the first NFT and the second NFT stored in the first user device 5a to be deleted (and (It is disabled), and the first NFT and second NFT are newly generated and output to the second user device 5b. The first NFT and the second NFT that have been created may be transmitted. Server device 2 will transmit the first NFT and Then, associate the second NFT with the second user (step st44).

[0103] Next, the second user device 5b receives information from the second user regarding the association between the first NFT and the second NFT. The request to release the lock is accepted (step st45). Then, the second user device 5b, Send this request to server device 2 (step st46).

[0104] Next, the second receiving means 2332 of the server device 2 receives the first NFT and the second NFT from the second user. Accepts a request to unassociate with the NFT (step st47). Unassociation means 236 This unassociates the first NFT from the second NFT (step st48).

[0105] Next, the second modification means 2352 changes the state of the first game medium in response to the above release. Specifically, the second modification means 2352 performs a process to change the state of the first game medium. One is to further modify the parameters of the first game medium, in other words, the first modification method. Generate change information to revert the parameter changes made to the first game medium by 2351. Step st49). Next, the second modification means 2352 changes the state of the first game medium. As one of the processes, the generated change information is sent to the second user device 5b (step s t50). The second user device 5b reflects the received change information in the first NFT, and the first Further modify the parameters of the media (returning them to their state before modification by the first modification means 2351), Lameter outputs a further modified first game medium (step st51).

[0106] To summarize, the control unit 23 (computer) of server device 2 controls the first game medium. The first nonfungible token (first NFT) is defined, and the second game medium is defined. Two non-fungible tokens (second NFTs) are associated with the first user. 1. Association means 2341: Request from the first user to associate the first NFT with the second NFT. A first receiving means 2331 accepts requests and, upon request, associates the first NFT with the second NFT. The second association means 2342, based on the second game medium defined by the second NFT, A first modification means 2351 for changing the state of the game medium, the first NFT and the second NFT Third association means 2: Disassociate with the first user and associate with the second user. 343. The second user has requested that the association between the first NFT and the second NFT be removed. The second receiving means 2332, upon request, unassociates the first NFT and the second NFT. A release means 236, and a second modification means 2 that changes the state of the first game medium in response to the release. It is intended to function as 352.

[0107] <Effects> According to this embodiment, the user can associate or unassociate NFTs, The condition of the trading card itself can be changed based on the frame, signature parts, etc. It is possible. The value of NFT trading cards can change depending on their condition, so the condition of the NFT trading card is important. When changing the state, users put in creativity and ingenuity to increase value and popularity. Exploring designs can be an enjoyable experience. Therefore, NFT The entertainment value can be improved by changing the state of the converted game medium.

[0108] [Differentiation] Although the present invention has been described based on the above embodiments, the present invention is not limited to the above embodiments. Not defined. The following cases are also included in this invention.

[0109] [First Modified Example] In the above embodiment, an example where the game medium defined by the NFT is a digital card has been described. However, the game medium defined by the NFT according to the present invention is not limited to this. The game medium defined by the NFT may be, for example, an item or a character used in the game. Moreover, the value medium defined by the NFT is not limited to the game medium. That is, the value medium defined by the NFT is not used within a specific game, and may be a digital card or the like simply for collection or for transactions between users. In this case, while a media image is associated with the value medium defined by the NFT, game parameters for use in the game are not associated.

[0110] [Second Modified Example] In the above embodiment, in the secondary distribution of the platform system 1, an example where the sale (transfer between users) of the second NFT unit of the card part P 2 is restricted has been described. However, the sales mode of the NFT according to the present invention is not limited to this. For example, in secondary distribution, it may be allowed to sell the second NFT unit that defines the second game medium. Also, for example, when setting an amount obtained by multiplying the selling price of the transaction target by a predetermined multiplication rate as a collection fee as in the example shown in the above embodiment, allowing the sale of the second NFT unit of the card part P may result in a low collection fee. In contrast, in the platform system 1, it may be covered by collecting a consideration for customizing the NFT trading card.

[0111] Here, referring to FIG. 7, allowing the sale of the second NFT unit in secondary distribution This section describes one example of a method for collecting payment for customizing NFT trading cards.

[0112] As shown in Figure 7, in platform system 1, for example, card parts You may charge a fee when customizing the main unit. For example, the following methods can be considered for collecting payment for the service. (a) The game medium required for customization (in Figure 7, "Customization Item") (as indicated) selling and purchasing and owning this game medium (as associated with the user) Subject to the following conditions, users can customize NFT trading cards. (i) When customization is performed, the user is required to pay a fee for the customization each time, and this customization The payment for the customization will be processed. For example, the payment for the customization will be made to card C1. The cost of combining parts P (labeled "combination cost" in Figure 7), or the combined card. This includes the cost of disassembling C1 and card part P (labeled "disassembly cost" in Figure 7). It can be done.

[0113] The second association means 2342, for example, subject to payment of consideration, the first NFT and the second Linking NFTs, and unlinking the first NFT from the second NFT. , at least one of the following may be permitted. Specifically, the second association means 2342 is For example, the first NFT of card C1 and frame P1 are linked, subject to payment of the association fee. Allowing the association of the second NFT and the merging of frame P1 with card C1 That's good too.

[0114] According to the above configuration, it is possible to associate the first NFT with the second NFT and to unassociate this NFT. For doing so, these fees can be collected. For example, platform systems The funds will be used for the operation of Tem1 and for payments to professional esports players listed on NFT trading cards. Therefore, it is likely that they will need to raise funds. When raising funds in this way, This funding source will be the collection of fees for customizing the Unagi NFT trading cards. This is possible. In particular, by allowing the sale of the second NFT on its own, the fees collected can be lower. In such cases, it can serve as an alternative source of funding.

[0115] The second association means 2342, for example, stipulates payment by the second user for the association. As an example, the first NFT and the second NFT may be associated. With such a configuration, The payment of consideration for linking one NFT with a second NFT is a prerequisite for the linking process. Therefore, it is possible to reliably collect compensation for the association.

[0116] The third association means 2343, for example, associates the first NFT and the second NFT. Regardless of whether or not, it is permitted to associate the first NFT with the second user on its own. Furthermore, it may be permitted to associate the second NFT with the second user independently. Step 2343 is associated with the first NFT of card C1 and the second NFT of signature part P2. Even if they are not combined, the second NFT unit of sign part P2 is the first unit You may allow the user to be unassociated with a second user and then associated with a second user. If so, the third association means 2343 transfers the second NFT alone from the first user to the second user. It can be resold (sold and purchased).

[0117] According to the above configuration, the third association means 2343 can associate each of the first NFT and the second NFT with the second user individually regardless of whether the first NFT and the second NFT are associated. Therefore, the user can transfer the second NFT alone to the second user, so that in the secondary circulation, the NFT related to the NFT trading card can be circulated more freely. Thus, the third association means 2343 can promote the circulation of the NFT related to the NFT trading card in the secondary circulation. The third association means 2343 may, for example, release the association with the first user for the first NFT and / or the second NFT and associate it with the second user on the condition that the second user pays the consideration for the purchase of the first NFT and / or the second NFT (hereinafter also referred to as "purchase consideration"). The third association means 2343 may, for example, when detecting that the payment settlement of the purchase consideration by the second user has been completed, release the association with the first user for the first NFT and / or the second NFT in response to this detection and associate it with the second user. The release means 236 may, for example, release the association between the first NFT and the second NFT on the condition that the second user pays the consideration for the release. The release means 236 may, for example, when detecting that the payment settlement of the consideration for the release by the second user has been completed, release the association between the first NFT and the second NFT in response to this detection. According to such a configuration, since the payment of the consideration for the release of the association between the first NFT and the second NFT is a prerequisite for the release, the consideration for the release can be reliably collected. Thus, NFTs related to NFT trading cards can be circulated more freely in secondary circulation. Therefore, the third association means 2343 can promote the circulation of NFTs related to NFT trading cards in secondary circulation. According to the above configuration, the third association means 2343 can associate each of the first NFT and the second NFT with the second user individually regardless of whether the first NFT and the second NFT are associated. For this reason, the user can transfer the second NFT alone to the second user, so that in secondary circulation, NFTs related to NFT trading cards can be circulated more freely.

[0118] The third association means 2343 may, for example, release the association with the first user for the first NFT and / or the second NFT and associate it with the second user on the condition that the second user pays the consideration for the purchase of the first NFT and / or the second NFT (hereinafter also referred to as "purchase consideration"). The third association means 2343 may, for example, when detecting that the payment settlement of the purchase consideration by the second user has been completed, release the association with the first user for the first NFT and / or the second NFT in response to this detection and associate it with the second user. The release means 236 may, for example, release the association between the first NFT and the second NFT on the condition that the second user pays the consideration for the release. The release means 236 may, for example, when detecting that the payment settlement of the consideration for the release by the second user has been completed, release the association between the first NFT and the second NFT in response to this detection and associate it with the second user. According to such a configuration, since the payment of the consideration for the release of the association between the first NFT and the second NFT is a prerequisite for the release, the consideration for the release can be reliably collected. The third association means 2343 may, for example, release the association with the first user for the first NFT and / or the second NFT and associate it with the second user on the condition that the second user pays the consideration for the purchase of the first NFT and / or the second NFT (hereinafter also referred to as "purchase consideration"). The third association means 2343 may, for example, when detecting that the payment settlement of the purchase consideration by the second user has been completed, release the association with the first user for the first NFT and / or the second NFT in response to this detection and associate it with the second user.

[0119] The release means 236 may, for example, release the association between the first NFT and the second NFT on the condition that the second user pays the consideration for the release. The release means 236 may, for example, when detecting that the payment settlement of the consideration for the release by the second user has been completed, release the association between the first NFT and the second NFT in response to this detection. According to such a configuration, since the payment of the consideration for the release of the association between the first NFT and the second NFT is a prerequisite for the release, the consideration for the release can be reliably collected. The release means 236 may, for example, release the association between the first NFT and the second NFT on the condition that the second user pays the consideration for the release. The release means 236 may, for example, when detecting that the payment settlement of the consideration for the release by the second user has been completed, release the association between the first NFT and the second NFT in response to this detection. According to such a configuration, since the payment of the consideration for the release of the association between the first NFT and the second NFT is a prerequisite for the release, the consideration for the release can be reliably collected.

[0120] [Third variation] In the above embodiment, an example was described in which each NFT is associated with a user individually, but The form of association of an NFT with a user is not limited to this. For example, NFT By combining multiple Reca, a collection of NFTs (so-called sets or packs) is generated, You may assign each set of NFTs to a user.

[0121] The control unit 23 may function as a combination means (not shown). The combination means is By combining multiple NFTs, a set of multiple NFTs is generated. A set of NFTs is: For example, a pack of first NFTs that defines card C1, or a second NFT that defines card part P. Set T, a first NFT defining card C1 and a second NFT defining card part P This includes sets of one pair. Combination methods include, for example, the final league of an esports tournament and The final round consisted of a total of 10 matches in the esports tournament's final league. In this case, the media of each of the final rounds of the games played in each of these 10 matches You may generate a pack containing 10 cards C1 with associated images.

[0122] [Fourth variation] In the above embodiment, the platform system 1 displays the NFTs it sells, The example described is that the user selects and purchases an NFT from among them, but the NFT in this embodiment Sales methods are not limited to this. NFTs can be sold in various ways, for example, by selecting from a selection of multiple NFTs. A lottery to select one or more NFTs based on lottery conditions such as a lottery table (so-called "serious" lottery) It may also be "ya". The sales method for NFTs is, for example, a lottery to select multiple NFTs. It could also be a so-called "pack gacha."

[0123] The memory unit 22 stores, for example, a lottery table (not shown) used by the lottery means described later. It may be used. The lottery table is used for a lottery, commonly known as a gacha, using a lottery method (described later). This is used when selecting NFTs and contains information on multiple NFTs. The list contains information about the NFT (e.g., name, parameters, etc.) and the selection rate determined by lottery. This is linked to (so-called winning probabilities and distribution rates).

[0124] "Gacha" refers to a system on server device 2 that selects from a lottery table based on predetermined selection ratios. This method involves selecting any NFT by lottery. The selected NFT will be attached to the user. To be given. “The game medium selected through gacha is given to the user / becomes owned by the user.” This means that the game medium defined by the NFT selected in the lottery process is associated with the user's identification information. This is synonymous with "connecting" or "being associated with."

[0125] The first association means 2341, for example, performs a lottery using a lottery means, and the result of the lottery The NFT may be associated with the user by means of the first association means 2341, For example, the NFT information of the NFT selected by the lottery method and the operation that sends the lottery request The user's identification information is associated with the token DB222. The NFT that was won as a result of this lottery (drawing from the gacha) will be awarded to the user.

[0126] —Method of drawing— The association means 234 may include, for example, a lottery means (not shown). The lottery means is The lottery is executed in response to the user's lottery execution instruction. The lottery means is, for example, the user's lottery instruction Accordingly, from the lottery table (not shown) stored in the memory unit 22, for each NFT, One or more NFTs will be randomly selected based on their selection ratio.

[0127] [Fifth variation] Although not shown in the above embodiment, the second platform of platform system 1 In transactions between users of the platform, distributed ledger technology (e.g., blockchain technology) is utilized. This may also be done. For example, on the second platform, transaction information may be shared on the user (edge) side. To manage them in a dispersed manner, multiple users including the first user device 5a and the second user device 5b The data may be distributed and stored on each of the 5 devices. With this configuration, the data can be stored between users. Transaction information indicating a trade can be distributed to user devices 5 and shared among users, so It can prevent information tampering. Also, it allows for the distributed management of transaction information among users. For example, the operator running a specific game does not need to centrally manage it, NFT trading cards can be used across various games, regardless of the user.

[0128] In the second platform, for example, the value of NFTs, i.e., NFTs between users Setting the consideration for the transfer is the user who is making the transaction to transfer the NFT (in the example above, the second Not only users 1 and 2, but also participants in the network of platform system 1. It may be set based on the consensus of multiple users.

[0129] [Other embodiments] The various control means and processing procedures described in the above embodiments are just examples, and the present invention, and This is not intended to limit the scope of its applications or uses. Various control means The processing procedure can be modified as appropriate without altering the essence of the present invention.

[0130] Games include action games, shooting games, role-playing games, and stains. This could be a simulation game, a board game, or a puzzle game, and various kinds It can be applied to games of this type.

[0131] In the above embodiment, the server device 2 and the multiple user devices 5 work together to program I have given examples of how to make it work, but it is not limited to these. All means of the program, that is, The reception means, association means, modification means, and cancellation means are used by the server device 2 alone and the user Device 5 alone, a communication terminal separate from the server device and user device 5, and combinations of these Two devices can be combined (for example, distributed processing on server device 2 and user device 5), and are equipped It may be provided. Also, the server device, user device, and communication terminal can function as an integrated unit. In such cases, the method used and the device on which it functions can be changed as appropriate.
