Description

The present invention relates to a transaction support system and a transaction support program.

In recent years, a transaction service has been provided for conducting transactions on NFT content, which is content data associated with a non-fungible token (NFT), on the Internet.

NFT is a non-fungible token issued on the blockchain. NFT owners and ownership history are recorded in the distributed ledger of the blockchain network. NFT content associated with such NFTs has non-fungible asset value and can be traded (eg, bought and sold) on the trading service.

A user who uses an NFT content transaction service is generally required to perform user authentication, for example, login authentication using authentication information such as a user ID and password when using the transaction service.

Patent Literature 1 describes a system for managing transaction services using digital points. In this system, after confirming whether the user is worthy of using the service (reliable person), user registration (membership registration) is performed, and only registered users can use the service. can be done.

Japanese Patent No. 7076671

In order to promote the popularization of NFT content, it is desired to implement a mechanism that arouses users' willingness to purchase and activates transactions in transaction services related to NFT content. Conventional log-in authentication is for ensuring security and has nothing to do with arousing purchase intentions.

In the prior art such as that described in Patent Document 1, proper transactions are promoted by allowing only trustworthy persons to use transaction services, but there is room for improvement in terms of motivating users to purchase. . Specifically, in the conventional technology, there is a problem that it is not possible to set/determine the conditions for whether or not a transaction can be made for each NFT content according to the user's status (rank). In addition, there is also the problem that unless the person is trustworthy in the first place, the existence and content of the NFT content handled by the transaction service cannot be noticed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a transaction support system and a transaction support program that can activate transactions related to NFT content and further promote the spread of NFT content.

A transaction support system according to a first aspect is a system that supports transaction services related to NFT content, which is content data associated with a non-fungible token (NFT). The transaction support system comprises a granting means for granting a user rank to the user based on parameters related to the user's purchasing behavior in the transaction service, and purchase of the NFT content for each NFT content handled by the transaction service. setting means for setting the user rank for which is permitted; presentation means for presenting information on the NFT content handled by the transaction service to the user according to the user's search operation; determining means for determining whether or not the user has the authority to purchase the NFT content of the user based on the user rank of the user. The presenting means presents to the user information regarding whether or not the user has the authority.

A transaction support program according to a second aspect provides a transaction support system that supports a transaction service related to NFT content, which is content data associated with a non-fungible token (NFT), to a parameter related to the user's purchasing behavior in the transaction service. Based on, a granting step of granting a user rank to the user, a setting step of setting the user rank that is permitted to purchase the NFT content for each of the NFT content handled by the transaction service, and the transaction service A presentation step of presenting information about the NFT content handled by the user according to the user's search operation, and whether the user has the authority to purchase the specific NFT content for which the information is presented, and a determining step of determining based on the user rank of the user. The presenting step includes presenting information to the user regarding whether the user is authorized to purchase the particular NFT content.

A transaction support system according to an embodiment will be described with reference to the drawings. In the description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.

(1) System Configuration Example FIG. 1 is a diagram showing a configuration example of a transaction support system according to this embodiment. The transaction support system according to this embodiment has a server 100 and a terminal 200 . The server 100 and the terminal 200 are connected to the network 10 and can communicate with each other via the network 10 . Network 10 includes the Internet. The network 10 may include a LAN (Local Area Network) and/or a WAN (Wide Area Network). Terminal 200 is a device operated by a user and having a communication function. The terminal 200 is, for example, a smart phone, a tablet terminal, a personal computer (PC), a wearable terminal, or the like.

The server 100 manages and provides a transaction service for conducting transactions regarding NFT content on the network 10 (Internet). NFT content refers to content data associated with an NFT. Server 100 may be a general-purpose computer such as a workstation or PC, or may be logically implemented by cloud computing.

The server 100 is communicably connected to the blockchain network 20 . The blockchain network 20 is composed of a plurality of nodes (computers) and manages a ledger in a distributed manner. Such distributed ledgers are managed in a way that is difficult to tamper with using a blockchain mechanism. Note that the detailed explanation of the distributed ledger management mechanism by blockchain is omitted here as it adopts a general one.

Tokens that can be issued by the blockchain network 20 include fungible tokens (FT) and non-fungible tokens (NFT). NFT is a non-substitutable token, unlike FT. NFTs can have unique values that distinguish them from other NFTs. An NFT has a unique identifier (NFT-ID) to allow distinction from other NFTs. NFTs, like FTs, are tradable through the blockchain network 20. NFT transaction history is recorded in the blockchain network 20 . The distributed ledger of the blockchain network 20 also records the NFT's owner and ownership history.

In this way, NFT content has an irreplaceable asset value, and can be traded (for example, traded) on the trading service managed by the server 100 . A user who uses the transaction service may be required to perform user authentication, for example, login authentication using authentication information such as a user ID and password when using the transaction service. In order to promote the popularization of NFT content, it is desired to implement a mechanism that arouses users' willingness to purchase and activates transactions in transaction services related to NFT content. Conventional log-in authentication is for ensuring security and has nothing to do with arousing purchase intentions.

FIG. 2 is a diagram for explaining the outline of the transaction support system according to this embodiment.

In this embodiment, the server 100 converts the content data corresponding to one of the real contents provided (for example, exhibited or sold) by the content provider (content holder) to the transaction service into an NFT. Publish one NFT content. A pair of such real content and NFT content is also referred to as a “content pair” or simply “content”. In the transaction service according to the present embodiment, such a content pair can be traded as a transaction unit. In the illustrated example, there is one content provider, but there may be multiple content providers. The content provider may be a person who owns the copyright (and/or the moral rights of the author) of the content, or a person who has other rights such as sales rights.

Here, real content refers to content that is a tangible object, such as an art work such as a figure or a painting. Content data corresponding to real content refers to content that expresses real content as data, such as photographic data of paintings, or two-dimensional image data or three-dimensional image data of figure characters. In the illustrated example, the real content #A is a character A figure, and the corresponding NFT content #A is character A's image data. Also, the real content #B is a character B figure, and the corresponding NFT content #B is character B image data. Furthermore, real content #C is a figure of character C, and corresponding NFT content #C is character C's image data. Note that the image data may be moving image data.

NFTization refers to issuing NFT content by associating NFT with content data corresponding to real content. For example, the server 100 issues an NFT to be associated with the content data in the blockchain network 20. Information specifying the content data and information specifying the owner of the content data are set in the NFT to be issued. When an NFT (NFT content) is transferred in the transaction service, the server 100 may issue a transaction in the blockchain network 20 to set the transferee user as the owner of the NFT (NFT content). As a result, the transferee user is recorded in the distributed ledger as the new owner of the NFT (NFT content).

In this way, in the transaction support system according to the present embodiment, by converting real content, which is a real work, into NFT at the same time, it is possible to issue a work (NFT content) that will never deteriorate digitally for the rest of its life. Artworks such as paintings and figurines are usually purchased for the purpose of appreciation and investment, but management becomes complicated due to aging and changes in lifestyle. In order to maintain the quality of the work, it is stored in a rental warehouse, etc., but in most cases, once stored, it is sold or transferred. On the other hand, since NFT content is digital data, it is easy to appreciate it in front of you. In addition, in the transaction support system according to the present embodiment, the value of the NFT content is guaranteed by associating the real content and the NFT content on a one-to-one basis. .

Under such a premise, the server 100 according to the present embodiment assigns a user rank to each user based on parameters related to the user's purchasing behavior in the transaction service. In the illustrated example, the user ranks are three levels of "high", "middle", and "low", but may be two levels of "normal member" and "premium member", or "S rank". ", "A rank", "B rank", and "C rank". In the following, an example in which the user rank has three levels of "high", "middle", and "low" will be mainly described.

For example, the server 100 assigns a higher user rank to a user registered with the transaction service as the degree of purchasing behavior indicated by the parameters related to purchasing behavior increases. That is, the server 100 appropriately updates the user rank of the user in accordance with the user's purchasing behavior regarding transaction services. This makes it possible to arouse the user's willingness to purchase the transaction service.

The server 100 sets a user rank permitted to purchase the NFT content for each NFT content handled in the transaction service. In the illustrated example, the server 100 sets a "high" rank as the user rank permitted to purchase NFT content #A. Therefore, a user given a "high" rank user rank (also referred to as a "high rank user") can purchase NFT content #A, but a user given a "medium" rank user rank (" (also referred to as "medium rank users") and users given a "low" rank user rank (also referred to as "low rank users") cannot purchase NFT content #A. In addition, the server 100 sets "medium" rank or higher as a user rank permitted to purchase NFT content #B. Therefore, high-rank users and medium-rank users can purchase NFT content #B, but low-rank users cannot purchase NFT content #B. Furthermore, the server 100 sets all ranks as user ranks permitted to purchase NFT content #C. Therefore, high-rank users, medium-rank users, and low-rank users can all purchase NFT content #C.

The server 100 presents information on the NFT content handled in the transaction service to the user according to the user's search operation (that is, the user's search operation on the terminal 200) (that is, displays the information on the user's terminal 200 ). The server 100 may present the user with information on all NFT contents handled by the transaction service if no specific search condition is specified by the user. Alternatively, when a specific search condition is specified by the user, the server 100 may present the user with information about NFT content that matches the specific search condition.

In any case, regardless of the user's user rank, the server 100 presents information on all NFT contents handled by the transaction service to the user according to the search operation. As a result, for example, low-rank users can know the existence and content of NFT content that can only be purchased by medium-rank users or high-rank users. Similarly, middle-rank users can know the existence and content of NFT content that only high-rank users can purchase. As a result, low-rank users and medium-rank users can be encouraged to promote purchasing behavior in order to raise their user ranks.

Based on the user rank of the user, the server 100 determines whether or not the user has the authority (also referred to as “purchase authority”) to purchase the specific NFT content for which the information is presented to the user. presents information to the user as to whether the user has For example, the server 100 determines, for each user, NFT content that can be purchased and NFT content that cannot be purchased at the user rank of the user, and presents information on each NFT content to the user in a manner that allows identification of purchase availability. may Alternatively, the server 100 determines whether or not the user has the purchase authority to purchase the NFT content that the user desires to purchase based on the user rank, and notifies the user whether or not the NFT content can be purchased. good.

If the server 100 determines that the user does not have purchase authority, the server 100 may present guidance information for the user to acquire purchase authority. For example, when the server 100 determines that the user does not have the purchase behavior of the specific NFT content, the purchase behavior required to acquire (rank up) the user rank required to purchase the specific NFT content. A Web page showing the conditions is displayed on the terminal 200 of the user.

Based on the user's operation, the server 100 sets the real content corresponding to the NFT content purchased by the user to be kept in an undelivered state. As described above, real content is often stored in a rental warehouse or the like in order to maintain the quality of the work, and there are users who think that content data (NFT content) is sufficient for ordinary viewing. Therefore, even a user who purchases a content pair of an NFT content and a real content and obtains ownership of them can keep the real content in an undelivered state without delivering the real content.

Even if the real content has not yet been delivered, the value of the NFT content is guaranteed because the real content is associated with the NFT content. In addition, when the real content has not yet been delivered, it is possible to keep the value of the real content high when reselling (secondary distribution) the NFT content and the corresponding real content. That is, the NFT content and the corresponding real content can be resold with the "real content distribution right" attached. Thus, in this embodiment, the user who purchased the NFT content and the corresponding real content can select whether or not to exercise the "real content delivery right" at the time of (or after) purchasing the content. ing.

(2) Server Configuration Example FIG. 3 is a diagram showing a configuration example of the server 100 according to this embodiment. The server 100 has a communication unit 110 , a storage unit 120 and a processing unit 130 . The communication unit 110, the storage unit 120, and the processing unit 130 are interconnected by a bus (not shown) or the like.

The communication unit 110 communicates with the terminal 200 via the network 10 under the control of the processing unit 130 . Communication by the communication unit 110 may be wired communication or may include wireless communication. The storage unit 120 includes various memories such as a ROM (Read Only Memory), a RAM (Random Access Memory), and an auxiliary storage device. The transaction support program executed by the processing unit 130 is stored in the ROM and/or auxiliary storage device of the storage unit 120, for example. The processing unit 130 is composed of one or more processors.

The storage unit 120 has a user database 121 that stores information about each user and a content database 122 that stores information about each content.

FIG. 4 is a diagram showing a configuration example of the user database 121 according to the embodiment. In the illustrated example, the user database 121 includes, for each user, a user ID, authentication information, user rank, total content purchase amount/number, predetermined content purchase history, and payment status of predetermined service usage fees. .

A user ID is an identifier that uniquely identifies a user. The authentication information is information used for user authentication, such as a password, but may also be biometric authentication information.

A user rank is a rank (status) given based on parameters relating to the user's purchasing behavior in the transaction service. The parameter is at least one of the total content purchase amount/number, the purchase history of the predetermined content, and the payment status of the predetermined service usage fee. The total content purchase amount/number is the total amount and/or number of NFT content purchased by the user in the transaction service. The predetermined content purchase history is a history of purchases of NFT content (for example, expensive NFT content) that the user satisfies a predetermined condition in the transaction service. The payment status of the prescribed service usage fee is the status of whether or not the user has paid a prescribed usage fee (for example, a fixed monthly fee) for the transaction service.

FIG. 5 is a diagram showing a configuration example of the content database 122 according to the embodiment. In the illustrated example, the content database 122 includes an NFT content ID, a real content ID, a purchase permission user rank, an owner, and real content delivery settings for each content (each content pair).

The NFT content ID is a serial number that uniquely identifies the NFT (NFT content). A real content ID is a serial number that uniquely identifies a real content.

The purchase-permitted user rank is information on the user rank permitted to purchase the content pair (that is, the minimum required user rank). The owner is information (user ID) of the owner of the content pair. The owner of the content pair may be the content provider at the time the content pair is put up for sale on the trading service. If the listed content pair is purchased on the trading service, the owner is updated to the content purchaser. If the content pair is resold (secondary distribution), the owner is updated to a new content purchaser.

The real content delivery setting is information indicating a setting as to whether or not to deliver the real content. The real content delivery setting may be information indicating whether or not the “real content delivery right” has been exercised. The content purchaser can select/set whether or not to deliver the real content (that is, whether or not to exercise the “right to deliver the real content”).

Returning to FIG. 3, by executing the transaction support program, the processing unit 130 performs a user authentication unit 131, a user rank granting unit 132, an NFT conversion unit 133, a content management unit 134, and a user rank setting unit 135. , an information presentation unit 136, and a user rank determination unit 137.

The user authentication unit 131 uses user authentication information to perform user authentication to confirm whether or not the user is a registered user registered in the transaction service. Even if the user is not registered with the transaction service, the user may be able to search for the NFT content handled by the transaction service. The user authentication unit 131 acquires a user ID and authentication information at the time of user registration (membership registration), and adds the user information to the user database 121 .

The user rank assigning unit 132 assigns a user rank to the user based on parameters relating to the user's purchasing behavior in the transaction service. The user rank assigning unit 132 may assign a higher user rank to a user registered in the transaction service as the degree of purchasing behavior indicated by the parameter increases. For example, the user rank assigning unit 132 may assign a higher user rank to the user as the total content purchase amount/number of the user increases. The user rank giving unit 132 may give a high user rank to a user who has a history of purchasing NFT content that satisfies a predetermined condition in the content purchase history. The user rank assigning unit 132 may assign a high user rank to a user who has paid a predetermined service usage fee. The user rank assigning unit 132 updates the user database 121 after assigning (updating) the user rank.

The NFT-forming unit 133 issues one NFT content corresponding to each real content that is a tangible object. When the NFT content is issued, the NFT conversion unit 133 adds content pair information to the content database 122 . The NFT conversion unit 133 may issue the NFT content at the timing of the first exhibition of the content. Alternatively, assuming a case where the content purchaser does not appear, the NFT unit 133 may suspend the issuance of the NFT content at the timing of the first exhibition of the content and issue the NFT content at the timing of the first purchase of the content.

The content manager 134 manages the content database 122 . When the user purchases the NFT content (and the corresponding real content) on the transaction service, the content management unit 134 grants ownership of the NFT content and the corresponding real content to the user. In addition, based on the user's operation (selection), the content management unit 134 sets the real content corresponding to the NFT content purchased by the user to be maintained in an undelivered state.

The user rank setting unit 135 sets a user rank permitted to purchase NFT content (that is, a required user rank) for each NFT content (and corresponding real content) handled in the transaction service. The user rank setting unit 135 may set the required user rank for each content according to the policy of the operator of the transaction service, or may set the required user rank for each content according to the policy of the content provider. good. For example, the user rank setting unit 135 may set a high user rank as the required user rank for content whose number of exhibitions is less than a certain number (that is, content with a high rarity value), or may set a high user rank as the required user rank for content whose price is above a certain amount. A high user rank may be set as the user rank.

The information presenting unit 136 presents information about NFT content handled in the transaction service to the user according to the user's search operation. In particular, the information presenting unit 136 presents information regarding all NFT contents handled in the transaction service to the user according to the search operation, regardless of the user's user rank. The information presentation unit 136 may be able to present information on NFT content handled in the transaction service even to users who have not been registered as users (member registration).

The user rank determination unit 137 determines based on the user rank whether or not the user has purchase authority to purchase the specific NFT content whose information is presented by the information presentation unit 136 . The user rank determination unit 137 may determine whether or not a user confirmed as a registered user who has undergone user registration (member registration) has purchase authority based on the user rank. Based on the determination result of the user rank determining section 137, the information presenting section 136 presents to the user information regarding whether or not the user has purchase authority. When it is determined that the user does not have purchase authority, the information presentation unit 136 presents guidance information for the user to acquire purchase authority.

(3) System Operation Example FIG. 6 is a diagram showing an operation example of the transaction support system according to the present embodiment.

In step S101, the user (terminal 200) may send a login request to the server 100 for logging into the transaction service (specifically, the website of the transaction service). The login request includes authentication information entered by the user. In step S102, the server 100 that has received the login request performs user authentication (login authentication) using the authentication information. In step S103, the server 100 transmits a response indicating the authentication result to the user (terminal 200). Here, the explanation will proceed assuming that the user authentication has succeeded. Note that user authentication may not be performed at this stage, and user authentication may be requested at the stage when the user makes a search request or content purchase request.

In step S<b>104 , the user (terminal 200 ) transmits a content search request to server 100 . The content search request includes content search conditions specified by the user. The content search condition may specify all content, may specify a specific category, or may specify a specific content.

In step S<b>105 , the server 100 that has received the content search request identifies the user's user rank from the user database 121 . In step S106, the server 100 searches the content database 122 for content according to the search conditions specified by the user. The order of steps S105 and S106 may be reversed. In step S107, the server 100 determines whether or not the user is authorized to purchase the content based on the user rank specified in step S105 and the required user rank of the content searched in step S106. When a plurality of contents are retrieved in step S106, the server 100 may determine whether or not the user has purchase authority for each content.

If it is determined that the user does not have purchase authority (step S108: NO), in step S109, server 100 may transmit guidance information for the user to acquire purchase authority to the user (terminal 200). good. On the other hand, if it is determined that the user has the purchase authority (step S108: YES), in step S110, the server 100 transmits to the user (terminal 200) information about the content for which the user has the purchase authority. When a plurality of contents are retrieved in step S106, the server 100 may transmit to the user (terminal 200) information indicating whether or not the user has purchase authority for each content. Terminal 200 displays the information received from server 100 .

In step S111, the user (terminal 200) transmits to server 100 a content purchase request for requesting purchase of content for which the user has purchase authority. The content purchase request includes information for specifying the target content. The content purchase request may include information indicating whether or not delivery of the real content among the target content is necessary (that is, whether or not the delivery right is to be exercised).

In step S112, the server 100 that has received the content purchase request performs purchase processing for the target content. For example, the server 100 grants ownership of the target content to the user. In addition, when it is selected that delivery of the real content is unnecessary, the server 100 sets the real content to be maintained in an undelivered state.

(4) Modification FIG. 7 is a diagram showing a modification of the operation of the transaction support system according to the above embodiment. In this modified example, a scenario is assumed in which real content is exhibited at an exhibition, a real store, or the like, and the purchase of the real content and the corresponding NFT content is desired.

In this modified example, the real content is attached with a code in which content information related to the real content is encoded. The code may be a one-dimensional code (eg, bar code) or a two-dimensional code (eg, QR code (registered trademark)). The content information includes information (for example, serial number) for identifying content. Note that the code attached to the real content may be a mode in which the code is affixed to the real content itself or its packaging, or a mode in which the code is written on a tag attached to the real content. may be

In step S201, the user (terminal 200) generates image data by reading a code with his own camera, and acquires content information by recognizing and decoding the code in the image data.

In step S202, the user (terminal 200) transmits to the server 100 an information request including the content information acquired in step S201. The information request may be a login request and/or a content search request as described above.

In step S<b>203 , the server 100 that has received the information request from the user (terminal 200 ) identifies the user's user rank from the user database 121 . In step S204, server 100 searches content database 122 for content according to the content information from the user (terminal 200). The order of steps S203 and S204 may be reversed. In step S205, the server 100 determines whether or not the user is authorized to purchase the content based on the user rank specified in step S203 and the required user rank of the content searched in step S204.

If it is determined that the user does not have purchase authority (step S206: NO), in step S207, server 100 may transmit guidance information for the user to acquire purchase authority to the user (terminal 200). good. On the other hand, if it is determined that the user has the purchase authority (step S206: YES), in step S208, the server 100 transmits to the user (terminal 200) information on the content for which the user has the purchase authority. Terminal 200 displays the information received from server 100 .

In step S209, the user (terminal 200) transmits to server 100 a content purchase request for requesting purchase of content for which the user has purchase authority. The content purchase request includes information for specifying the target content. The content purchase request may include information indicating whether or not delivery of the real content among the target content is necessary (that is, whether or not the delivery right is to be exercised).

In step S210, the server 100 that has received the content purchase request performs purchase processing for the target content. For example, the server 100 grants ownership of the target content to the user. In addition, when it is selected that delivery of the real content is unnecessary, the server 100 sets the real content to be maintained in an undelivered state.
