[Overview of information processing system S]
FIG. 1 is a schematic diagram of an information processing system S according to this embodiment. The information processing system S includes a management server 1 and user terminals 2 . The information processing system S may include devices such as other servers and terminals.

The management server 1 (information processing device) is a computer for managing information about crypto assets and registration data, which is electronic data traded between users. The management server 1 can communicate with user terminals 2 via a network.

Crypto assets can be used for payment and the like, and are electronic assets different from legal currencies (Japanese yen, US dollar, etc.). A crypto-asset may be an electronic asset backed by legal currency, such as an electronic asset with a value and guarantee equivalent to that of legal currency. Crypto assets are issued to users by issuers such as local governments and companies. A crypto-asset is associated with the user holding the crypto-asset, for example, in a storage device, and is transferred from one user to another when used for payment.

A crypto-asset is an electronic asset managed by, for example, a blockchain. Crypto assets are not limited to blockchains, and may be electronic assets managed by a database or the like. Crypto assets are managed in units of assets, which are predetermined units used for settlement (for example, units in circulation). Hereinafter, the asset unit of crypto assets is called a coin, but other names may be used.

In this embodiment, crypto assets are, for example, regional digital currencies that can be used in a predetermined region. Payments using crypto assets, which are regional digital currencies, can be performed at stores within a predetermined area, and cannot be performed at stores outside the area. Also, settlement using crypto assets, which are regional digital currencies, may be executable only at predetermined stores (for example, registered stores) within a predetermined area.

Also, when a product is bought and sold between two users (for example, a person-to-person transaction website), the individual user who sells the product may be treated as a store. In this case, it may be determined whether or not the store is located within the area based on the address of the user who sells the product.

The management server 1 manages the crypto assets held by each user in the crypto asset account associated with the user. The management server 1 transfers the crypto-asset from one user's crypto-asset account to another user's crypto-asset account, for example, by changing the holder of the crypto-asset from one user to another user in the blockchain.

Registered data is electronic data such as pictures, photographs, music, programs, game characters and items that are traded between users. The user owns the registration data, for example, by being recorded as having ownership of the registration data in the storage device.

Ownership of registration data is managed as NFT (Non-Fungible Token) by blockchain, for example. NFT is, for example, information indicating data identification information (data ID) for identifying registration data and user identification information (user ID) for identifying a user who owns the registration data. The data ID is, for example, a URI (Uniform Resource Identifier) for accessing registration data. The registration data is stored in a storage device on the network corresponding to the URI. In addition, ownership of registered data is not limited to blockchain, and may be managed by a database or the like.

The management server 1 manages ownership of each user's registered data in a data management account associated with the user. The management server 1 transfers the ownership of the registration data from one user's data management account to another user's data management account, for example, by changing the owner of the registration data from one user to another user in the blockchain. do.

The user terminal 2 is a computer used by users such as registrants and purchase requesters. A registrant is, for example, a user who has registered registration data with the management server 1 . A purchase requester is, for example, a user who wishes to purchase registration data using crypto assets. The user terminal 2 is, for example, a smart phone, a tablet terminal, or a personal computer. The user terminal 2 has an operation unit such as a touch panel or a keyboard for receiving operations, and a display unit such as a liquid crystal display for displaying information. The user terminal 2 can communicate with the management server 1 via a network.

The outline of the processing executed by the information processing system S according to this embodiment will be described below. The management server 1 receives a registration request for registering registration data from the user terminal 2 used by the registrant (1). The registration request is, for example, information indicating the data ID of the registration data and the user ID of the registrant.

In response to the registration request, the management server 1 associates and registers the data ID of the registration data and the registrant's user ID. As a result, when the registration data is registered, the registrant becomes the owner of the registration data. After that, when the ownership of the registered data is transferred due to a transfer between users, etc., a user different from the registrant becomes the owner of the registered data.

The management server 1 receives a purchase request for purchasing registration data from the user terminal 2 used by the purchase requester (2). The purchase request is, for example, information indicating the user ID of the purchase requester and the crypto assets used for the purchase.

The management server 1 determines whether or not the registered data can be purchased with the crypto assets based on the relationship between the attributes of the registrant and the conditions under which the crypto assets can be used (3). For example, the management server 1 determines that the registered data can be purchased with cryptographic assets when the registrant's attributes such as location, nationality, age, and gender satisfy conditions associated with the cryptographic assets in advance.

On the condition that it is determined that the registration data can be purchased with the crypto-asset, the management server 1 changes the user holding the crypto-asset from the purchase requester to the holder (4), and holds the registration data. Change the user from the holder to the purchase requester (5). As a result, the purchase requester pays the crypto asset corresponding to the price of the registration data to the holder, and the purchase requester becomes the new holder of the registration data.

In this way, the information processing system S enables the purchase requester to purchase the registered data with crypto assets on the condition that the attributes of the registrant who registered the registration data satisfy the conditions for using the crypto assets. As a result, the information processing system S can limit the use of crypto assets to the purchase of registration data registered by users with specific attributes, and thus can activate economic circulation in users with specific attributes.

[Configuration of information processing system S]
FIG. 2 is a block diagram of the information processing system S according to this embodiment. In FIG. 2, arrows indicate main data flows, and there may be data flows other than those shown in FIG. In FIG. 2, each block does not show the configuration in units of hardware (apparatus), but the configuration in units of functions. As such, the blocks shown in FIG. 2 may be implemented within a single device, or may be implemented separately within multiple devices. Data exchange between blocks may be performed via any means such as a data bus, network, or portable storage medium.

The management server 1 has a communication section 11 , a storage section 12 and a control section 13 . The management server 1 may be configured by connecting two or more physically separated devices by wire or wirelessly. Moreover, the management server 1 may be configured by a cloud that is a collection of computer resources.

The communication unit 11 has a communication controller for transmitting and receiving data to and from the user terminal 2 via the network. The communication unit 11 notifies the control unit 13 of data received from the user terminal 2 via the network. Also, the communication unit 11 transmits data output from the control unit 13 to the user terminal 2 via the network.

The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, and the like. The storage unit 12 stores programs executed by the control unit 13 in advance. In addition, the storage unit 12 stores in advance attribute information indicating attributes of registrants of registration data. In addition, the storage unit 12 stores in advance usage availability conditions, which are the conditions under which the crypto-assets can be used. Further, the storage unit 12 stores in advance the price of the registration data specified by the owner of the registration data. The storage unit 12 may be provided outside the management server 1, in which case data may be exchanged with the control unit 13 via a network.

The control unit 13 has a registration unit 131 , a registration data processing unit 132 , a reception unit 133 , a determination unit 134 , an output unit 135 and a crypto-asset processing unit 136 . The control unit 13 is a processor such as a CPU (Central Processing Unit), for example. It functions as an output unit 135 and a crypto asset processing unit 136 . Processing performed by the registration unit 131, the registration data processing unit 132, the reception unit 133, the determination unit 134, the output unit 135, and the crypto-asset processing unit 136 will be described later.

[Account and account description]
First, a method for managing crypto assets and registered data by the information processing system S will be described. FIG. 3 is a schematic diagram for explaining how the information processing system S manages crypto assets and registered data.

The management server 1 manages the crypto-assets held by each of a plurality of users in crypto-asset accounts. A cryptocurrency account for each of a plurality of users is associated with that user's user ID. The management server 1 deposits and withdraws crypto-assets to and from crypto-asset accounts, or transfers currency between a plurality of crypto-asset accounts, as crypto-asset management.

The management server 1 uses, for example, a block chain to manage cryptographic assets with coins as asset units. The management server 1 stores, for example, data (blocks) in which the user ID of the user and the content of transactions in the user's cryptocurrency account are associated as a block chain on one or more storage devices on the network. . Each block contains one or more transactions that indicate that cryptocurrency has been transferred between the user's cryptocurrency accounts. Each block in the blockchain contains a hash value generated according to a predetermined rule, and by confirming the consistency of hash values between blocks, the correctness of the entire blockchain is guaranteed.

The management server 1 stores, for example, data that associates a user's user ID with a cryptographic asset managed in the user's cryptographic asset account on the storage unit 12 of the management server 1, not limited to blockchain. It may be stored as a database.

The management server 1 manages registration data held by each of a plurality of users in a data management account. A data management account for each of the plurality of users is associated with that user's user ID. As management of registration data, the management server 1 grants ownership of registration data to a data management account, or transfers ownership of registration data between a plurality of data management accounts.

The management server 1 manages ownership of registration data using, for example, blockchain. The management server 1 blocks, for example, data (blocks) indicating an NFT that associates the data ID of the registration data with the user ID of the user who owns the registration data on one or more storage devices on the network. Store as a chain. Each block contains one or more transactions that indicate that an NFT has been transferred between the user's data custody accounts. Each block in the blockchain contains a hash value generated according to a predetermined rule, and by confirming the consistency of hash values between blocks, the correctness of the entire blockchain is guaranteed.

The management server 1 is not limited to a block chain. For example, the storage unit 12 of the management server 1 stores data that associates a user's ID with ownership rights of registered data managed in the user's data management account. may be stored as a database on the

It is desirable that the data ID of the registration data (for example, the NFT described above) and the crypto assets used to purchase the registration data are managed on the same platform. In this case, the platform used by the management server 1 is a platform that records both data IDs and cryptographic assets using one block chain. As a result, the management server 1 can manage the data IDs of the registered data and the crypto assets on a common platform, and can reduce the effort required for system maintenance and operation.

A user associated with a data management account (e.g., a user holding registration data) and a user associated with a crypto asset account (e.g., a user holding crypto assets) are managed using a common user ID. preferably As a result, the management server 1 can allow the user to easily grasp the holding status of the registered data and crypto assets using one user ID.

[Description of registration process]
A configuration for the information processing system S to execute processing for registering registration data will be described below. The user terminal 2 used by the registrant transmits a registration request for registering registration data to the management server 1 in response to the predetermined operation performed by the registrant. The registration request is, for example, information indicating the data ID of the registration data and the user ID of the registrant.

In the management server 1 , the registration unit 131 receives a registration request from the user terminal 2 . The registration unit 131 registers the registration data by notifying the registration data processing unit 132 of information for associating the data ID and the user ID indicated by the registration request and storing them in the storage device. The registration data processing unit 132 grants ownership of the registration data to the registrant according to the information notified from the registration unit 131 . The registration data processing unit 132, for example, adds a transaction to the blockchain to register the NFT associated with the data ID and user ID indicated by the registration request in the data management account of the registrant. As a result, when the registration data is registered, the registrant becomes the owner of the registration data.

When ownership of the registered data is transferred by assignment or the like between users, the registered data processing unit 132 transfers the ownership of the registered data between users. The registration data processing unit 132, for example, transfers the ownership of the registration data to be transferred from the data management account of the owner before the transfer (i.e., the registrant or other user) to the data of the owner after the transfer to the blockchain. Add a transaction to indicate the transfer to a managed account. Hereinafter, a user who has ownership of registered data at the time the registered data is traded is referred to as a holder of the registered data.

[Description of transfer process]
The configuration for the information processing system S to execute the process of transferring ownership of registration data will be described below. In the management server 1, the reception unit 133 acquires the user IDs of the registrants and holders of the registration data based on information stored in the blockchain or database. The reception unit 133 also acquires the attribute information of the registrant of the registration data, which is stored in advance in the storage unit 12 . The reception unit 133 also acquires the price of registration data stored in the storage unit 12 in advance. When a plurality of pieces of registration data are registered in the blockchain or database, the management server 1 performs subsequent processing for each piece of registration data.

The reception unit 133 transmits registration data information including user IDs of registrants and holders, attribute information of registrants, and prices of registration data to the user terminal 2 used by the purchase requester. The user terminal 2 displays the registration data information received from the management server 1 on the display unit. When the purchase requester wishes to purchase the registration data held by the holder, the purchase requester designates the crypto assets to be used for purchasing the registration data on the user terminal 2 used by the purchase requester.

FIG. 4 is a schematic diagram of an exemplary screen displayed by the user terminal 2 in this embodiment. For example, based on the registration data information received from the management server 1, the user terminal 2 receives the content of the registration data held by the owner, the user ID of the registrant and the owner of the registration data, and the registrant's attribute information ( The location of the registrant in FIG. 4) and the price of the registration data are displayed on the display unit.

The user terminal 2 accepts designation of crypto assets to be used for purchasing registration data. The user terminal 2 transmits a purchase request to the management server 1 for purchasing the registration data held by the holder using cryptocurrency in response to the predetermined operation performed by the purchase requester. The purchase request is, for example, information indicating the user ID of the purchase requester, the data ID of the registration data to be purchased, and the cryptographic asset specified by the purchase requester.

In the management server 1 , the accepting unit 133 accepts a purchase request from the user terminal 2 . The determining unit 134 acquires, for example, attribute information indicating the attribute of the registrant who registered the registration data corresponding to the data ID indicated by the purchase request, stored in advance in the storage unit 12 . The attribute information includes, for example, the region (location, etc.) associated with the registrant, the nationality of the registrant, the age of the registrant, the gender of the registrant, and the qualifications (predetermined national qualifications, etc.) of the registrant. is information indicating at least one of

Based on the relationship between the attribute of the registrant indicated by the acquired attribute information and the cryptographic asset indicated by the purchase request, the determination unit 134 determines whether the registered data corresponding to the data ID indicated by the purchase request can be purchased with the cryptographic asset. determine whether or not

The determining unit 134 acquires, for example, a usage availability condition stored in the storage unit 12 in advance, which is a condition for using the crypto asset. The availability condition is, for example, that at least one of the region associated with the registrant, the registrant's nationality, the registrant's age, the registrant's sex, and the registrant's qualifications is a predetermined value. or within a predetermined range. If the attribute of the registrant indicated by the attribute information satisfies the acquired availability condition, the determining unit 134 determines that the registered data can be purchased with the crypto asset. Determine that it is not purchasable.

As will be described later in a modified example, the determination unit 134 may determine whether or not the registration data can be purchased with crypto assets before the reception unit 133 receives the purchase request.

FIGS. 5(a) and 5(b) are schematic diagrams for explaining a method for determining whether or not the registration data can be purchased with crypto assets by the determination unit 134. FIG. FIG. 5A shows an example in which the determination unit 134 makes a determination based on the area associated with the registrant.

In this case, the crypto asset can be used, for example, for settlement at stores within a predetermined usage area, and cannot be used for settlement at stores outside the usage area. Crypto assets are issued, for example, by local governments that have jurisdiction over areas where they can be used. The availability condition is that the area associated with the registrant is included in the areas where the crypto assets can be used.

The determination unit 134 compares the area associated with the registrant indicated by the registrant's attribute with the crypto-asset available area. The area associated with the registrant is, for example, the area under the jurisdiction of the local government that is the registrant, or the area where the store that is the registrant is located. For example, the determination unit 134 determines that the registered data can be purchased with crypto assets if the registrant is a municipality that has jurisdiction over the available area or a store within the available area, and if not, It is determined that the registered data is not purchasable with crypto assets.

As a result, the management server 1 can limit the use of crypto-assets to the purchase of registration data registered by a registrant related to the crypto-assets available area, thereby suppressing the outflow of crypto-assets outside of the available areas. , can activate economic circulation in available areas.

FIG. 5B shows an example in which the determination unit 134 makes a determination based on attributes of the registrant outside the area associated with the registrant. The determining unit 134 converts at least one of the registrant's nationality, the registrant's age, the registrant's sex, and the registrant's qualification indicated by the registrant's attributes to the value indicated by the availability condition or Compare with range. For example, if the registrant has the nationality of a specific country, if the registrant is of a specific age (young or elderly), if the registrant is of a specific gender, or if the registrant is It is determined that the registered data can be purchased with the cryptocurrency when the user has a specific qualification, and otherwise, it is determined that the registered data cannot be purchased with the cryptographic currency.

As a result, the management server 1 can limit the use of crypto assets to the purchase of registration data registered by a registrant with a specific attribute, thereby suppressing the outflow of crypto assets to users with specific attributes. It is possible to activate the economic circulation in the user who has the attribute of.

The output unit 135 determines that the registration data cannot be purchased with the cryptographic asset indicated by the purchase request on condition that the receiving unit 133 has received the purchase request and the determination unit 134 has determined that the registration data cannot be purchased with the cryptographic asset. to the user terminal 2. The user terminal 2 displays the information received from the management server 1 on the display unit.

FIG. 6 is a schematic diagram of a screen displayed by the user terminal 2 in this embodiment. Based on the information received from the management server 1, for example, the user terminal 2 displays a message on the display unit indicating that the registered data cannot be purchased with the crypto assets specified by the purchase requester. As a result, the user can easily understand that the registered data cannot be purchased with the specified cryptographic asset, and can request the purchase of the registered data using another cryptographic asset.

On the other hand, the output unit 135 changes the user holding the crypto assets indicated by the purchase request from the purchase requester to the holder on condition that the determination unit 134 determines that the registered data can be purchased with the crypto assets. and a registration data transfer instruction for changing the user holding the registration data from the holder to the purchase requester. The crypto-asset transfer instruction is, for example, information indicating the purchase requester's user ID, the owner's user ID, and the amount of crypto-asset corresponding to the price of the registration data. The registration data transfer instruction is, for example, information indicating the purchase requester's user ID, the owner's user ID, and the data ID of the registration data.

The output unit 135 notifies the crypto-asset processing unit 136 of the crypto-asset transfer instruction. The crypto-asset processing unit 136 transfers the crypto-asset corresponding to the price of the registration data from the purchase requester's crypto-asset account to the holder's crypto-asset account according to the crypto-asset transfer instruction output by the output unit 135 . The crypto-asset processing unit 136, for example, sends to the blockchain a transaction indicating that one or more coins corresponding to the price of the registration data are transferred from the purchase requester's crypto-asset account to the holder's crypto-asset account. to add.

The output unit 135 notifies the registration data processing unit 132 of the registration data transfer instruction. The registration data processing unit 132 transfers ownership of the registration data from the data management account of the owner to the data management account of the purchase requester in accordance with the registration data transfer instruction output by the output unit 135 . The registration data processing unit 132 adds, for example, to the blockchain a transaction indicating the transfer of ownership of the registration data from the holder's data management account to the purchase requester's data management account. After that, the purchase requester becomes the new owner of the registered data, and the registration data purchased by the purchase requester can be purchased by a person other than the purchase requester using crypto assets.

Furthermore, when the registration data is purchased, the output unit 135 outputs information for giving the purchase requester the crypto assets or points that can be used in the area where the crypto assets used for the purchase are available. may In addition, when the registration data is purchased, the output unit 135 outputs to the registrant information for granting the crypto assets or points that can be used in the area where the crypto assets used for the purchase are available. may The cryptographic asset given to the purchase requester or registrant is, for example, the cryptographic asset used to purchase the registration data. A crypto asset given to a purchase requester or a registrant is a point that can be used for payment and is different from the crypto asset. Points, for example, are managed in a crypto-assets account using a blockchain, similar to crypto-assets.

The output unit 135, for example, calculates the value of crypto assets or points given to the purchase requester or registrant such that the higher the price of the purchased registration data, the greater the value. The output unit 135 adds, for example, to the blockchain a transaction indicating that the calculated value of the cryptographic assets or points is added to the cryptographic asset account of the purchase requester. As a result, the management server 1 can give crypto assets or points to the purchase requester in response to the purchase requester's purchase of the registration data, thereby promoting the purchase of the registration data by the purchase requester.

Also, the output unit 135 adds, for example, to the blockchain a transaction indicating that the calculated value of the crypto-asset or points is added to the crypto-asset account of the registrant. As a result, the management server 1 can provide cryptographic assets or points to registrants in accordance with the purchase requester's purchase of the registration data, thereby promoting the registration and sales of the registration data by the registrants.

[Sequence of information processing method]
FIG. 7 is a sequence diagram of an exemplary information processing method executed by the information processing system S according to this embodiment. The user terminal 2 used by the registrant transmits a registration request for registering registration data to the management server 1 in response to the predetermined operation performed by the registrant (S11).

In the management server 1 , the registration unit 131 receives a registration request from the user terminal 2 . The registration unit 131 registers the registration data by notifying the registration data processing unit 132 of information for associating the data ID and the user ID indicated by the registration request and storing them in the storage device (S12). The registration data processing unit 132 grants ownership of the registration data to the registrant according to the information notified from the registration unit 131 . As a result, when the registration data is registered, the registrant becomes the owner of the registration data. When ownership of the registered data is transferred by assignment or the like between users, the registered data processing unit 132 transfers the ownership of the registered data between users.

The reception unit 133 transmits registration data information including the user IDs of the registrant and holder, the attribute information of the registrant, and the price of the registration data to the user terminal 2 used by the purchase requester ( S13). The user terminal 2 of the purchase requester displays the registration data information received from the management server 1 on the display unit.

The user terminal 2 of the purchase requester sends a purchase request to the management server 1 to purchase the registration data held by the holder using the crypto assets in response to the predetermined operation performed by the purchase requester. Send (S14).

In the management server 1 , the accepting unit 133 accepts a purchase request from the user terminal 2 . The determining unit 134 acquires, for example, attribute information indicating the attribute of the registrant of the registration data corresponding to the data ID indicated by the purchase request, stored in advance in the storage unit 12 . Based on the relationship between the attribute of the registrant indicated by the acquired attribute information and the cryptographic asset indicated by the purchase request, the determination unit 134 determines whether the registered data corresponding to the data ID indicated by the purchase request can be purchased with the cryptographic asset. It is determined whether or not (S15).

[Effects of Embodiment]
According to the information processing system S according to the present embodiment, the management server 1 allows the purchase requester to submit the registration data on condition that the attribute of the registrant who registered the registration data satisfies the conditions under which the cryptocurrency can be used. Make it purchasable with crypto assets. As a result, the information processing system S can limit the use of crypto assets to the purchase of registration data registered by users with specific attributes, and thus can activate economic circulation in users with specific attributes.

[Modification]
In the above-described embodiment, it is determined whether or not the registered data can be purchased with crypto assets after the purchase requester makes a purchase request. It is determined whether the data can be purchased with crypto assets. Differences from the above-described embodiment will be mainly described below.

Before the purchase requester makes a purchase request, the determination unit 134 in the management server 1 acquires the user IDs of the registrant and owner of the registration data based on information stored in the blockchain or database. The determination unit 134 also acquires the attribute information of the registrant of the registration data, which is stored in advance in the storage unit 12 . Further, the determination unit 134 acquires the price of registration data stored in advance in the storage unit 12 . When a plurality of pieces of registration data are registered in the blockchain or database, the management server 1 performs subsequent processing for each piece of registration data.

Based on the relationship between the attribute of the registrant indicated by the acquired attribute information and one or more cryptographic assets that can be used to purchase the registration data, the determining unit 134 determines whether the registered data can be purchased with the cryptographic asset. determine whether or not One or a plurality of crypto assets that can be used to purchase registration data are set in the information processing system S in advance.

The determining unit 134 acquires, for example, a usage availability condition stored in the storage unit 12 in advance, which is a condition for using the crypto asset. The availability condition is, for example, that at least one of the region associated with the registrant, the registrant's nationality, the registrant's age, the registrant's sex, and the registrant's qualifications is a predetermined value. or within a predetermined range. If the attribute of the registrant indicated by the attribute information satisfies the acquired availability condition, the determining unit 134 determines that the registered data can be purchased with the crypto asset. Determine that it is not purchasable.

The reception unit 133 receives the registration data information including the user IDs of the registrants and holders, the attribute information of the registrants, and the price of the registration data by the determination unit 134 for each of one or a plurality of crypto assets. It is transmitted to the user terminal 2 used by the purchase requester together with determination information indicating whether the purchase is possible or not. The user terminal 2 displays the registration data information and determination information received from the management server 1 on the display unit.

FIG. 8 is a schematic diagram of an exemplary screen displayed by the user terminal 2 in this modified example. For example, based on the registration data information received from the management server 1, the user terminal 2 stores the content of the registration data held by the owner, the user ID of the registrant and the owner of the registration data, and the attribute information of the registrant. , the price of the registration data, and are displayed on the display unit.

In addition, for example, based on the determination information received from the management server 1, the user terminal 2 determines whether or not the registration data can be purchased for each of one or a plurality of crypto assets that can be used to purchase the registration data. Display on the display unit. The user terminal 2, for example, makes it possible to designate cryptographic assets for which registration data is purchasable, and makes cryptographic assets for which registration data is not purchasable, undesignable, according to the judgment result.

The user terminal 2 accepts designation of a crypto asset to be used for purchasing the registration data from among one or a plurality of crypto assets determined to be purchasable for the registration data. The user terminal 2 transmits a purchase request to the management server 1 for purchasing the registration data held by the holder using cryptocurrency in response to the predetermined operation performed by the purchase requester. The purchase request is, for example, information indicating the user ID of the purchase requester, the data ID of the registration data to be purchased, and the cryptographic asset designated by the purchase requester.

In the management server 1 , the accepting unit 133 accepts a purchase request from the user terminal 2 . The determination unit 134 may re-determine whether or not the registered data can be purchased with the crypto assets indicated by the purchase request. may

The output unit 135 sends a purchase request to the user who owns the cryptographic asset indicated by the purchase request on the condition that the receiving unit 133 has received the purchase request and the determining unit 134 has determined that the registered data can be purchased with the cryptographic asset. A crypto asset transfer instruction for changing from a person to a holder and a registration data transfer instruction for changing a user holding registration data from a holder to a purchase requester are output.

According to the information processing system S according to the present modification, before the purchase requester makes a purchase request, it is possible to notify the purchase requester whether or not the registration data can be purchased with crypto assets. It is possible to make it easier to select the crypto assets to be used for purchasing. In addition, as in the above-described embodiments, the information processing system S can limit the use of crypto assets to the purchase of registered data registered by a user with a specific attribute, thereby activating economic circulation for users with a specific attribute. can be made
