The present invention relates to an information processing device, an information processing method, and a program.

Conventionally, systems for managing merchandise transactions between individuals are known (see, for example, Patent Document 1).

JP 2017-134767 A

However, if users are free to sell (resell) products and other commercial materials that they have purchased from sellers, businesses related to those products, including the seller who sold them to the user, may suffer disadvantages. For this reason, there is a need to provide a mechanism for restricting users from selling commercial materials.

Therefore, the present invention has been made in consideration of these points, and aims to provide a mechanism for restricting users from selling merchandise.

The information processing device according to the first aspect of the present invention has an acquisition unit that acquires, from a seller that sold the set of products to the user, identification information of the set of products, which are at least any of goods and services, and identification information of a user who purchased the set of products, and a token management unit that executes a process of issuing a provision token to be used to provide some of the products included in the set of products based on the identification information of the set of products and the identification information of the user.

The provision token may be issued on a blockchain with the user as the holder.

The acquisition unit may acquire a request for issuing the provision token, the request including identification information of the set product and identification information of the user, and the token management unit may execute a process for issuing the provision token when the acquisition unit acquires the request for issuing the provision token.

The information processing device may further include a storage unit that stores calculation conditions for calculating the value generated when the provision token is sold, the calculation conditions being referenced when the provision token is sold, and the token management unit may execute a process for issuing the provision token in which a portion of the products included in the set product is associated with the calculation conditions stored in the storage unit.

The compensation may be a refund amount refunded to a seller who sold the set product to the user when the provision token is sold, and the information processing device may further have a transfer processing unit that executes processing to transfer assets equivalent to the refund amount calculated based on the calculation conditions associated with the provision token to the seller in response to a sales processing request from the seller, who is the user, to sell the provision token to a buyer, and the token management unit may execute processing to change the holder of the provision token from the seller to the buyer.

The compensation may be a refund amount refunded to a provider who provides the merchandise based on the provision token sold when the provision token is sold, or the information processing device may further have a transfer processing unit that executes processing to transfer assets equivalent to the refund amount calculated based on the calculation conditions associated with the provision token to the provider in response to a sales processing request in which the seller, who is the user, sells the provision token to a buyer, or the token management unit may execute processing to change the holder of the provision token from the seller to the buyer.

The consideration may be a refund amount refunded to another provider who provides the product based on other provision tokens different from the provision token being sold among the provision tokens corresponding to each of the multiple products included in the set product when the provision token is sold, and the information processing device may further have a transfer processing unit that executes processing to transfer assets equivalent to the refund amount calculated based on the calculation conditions associated with the provision token to the other provider in response to a sales processing request in which the seller, who is the user, sells the provision token to a seller, and the token management unit may execute processing to change the holder of the provision token from the seller to the seller.

The consideration may be the sales price at which the provision token is sold, and the information processing device may further have a transfer processing unit that executes processing to transfer assets equivalent to the sales price calculated based on the calculation conditions associated with the provision token from the seller to the seller in response to a sales processing request from the seller, who is the user, to sell the provision token to the seller, and the token management unit may execute processing to change the holder of the provision token from the seller to the seller.

The calculation conditions may include at least one of an upper limit value of the total amount of the sales price of the provision tokens corresponding to each of the multiple products included in the set product and a lower limit value of the total amount, and when the calculation conditions include the upper limit value, the transfer processing unit may execute a process to transfer assets equivalent to the sales price calculated so that the total amount does not exceed the upper limit value from the seller to the seller, and when the calculation conditions include the lower limit value, the transfer processing unit may execute a process to transfer assets equivalent to the sales price calculated so that the total amount does not fall below the lower limit value from the seller to the seller.

The calculation conditions may include at least one of an upper limit value of the selling price and a lower limit value of the selling price, and the transfer processing unit may execute a process to transfer assets equivalent to the selling price calculated so as not to exceed the upper limit value from the buyer to the seller when the calculation conditions include the upper limit value, and execute a process to transfer assets equivalent to the selling price calculated so as not to fall below the lower limit value from the buyer to the seller when the calculation conditions include the lower limit value.

The calculation conditions may include at least one of an upper limit value of a set sales price, which is the sales price of a set provision token, which is a set of multiple provision tokens corresponding to multiple products that are part of all of the products included in the set product, and a lower limit value of the set sales price. In response to the sales processing request in which the seller sells the set provision token to the buyer, if the calculation conditions include the upper limit value, the transfer processing unit may execute a process to transfer assets equivalent to the set sales price calculated so as not to exceed the upper limit value from the buyer to the seller, and if the calculation conditions include the lower limit value, the transfer processing unit may execute a process to transfer assets equivalent to the set sales price calculated so as not to fall below the lower limit value from the buyer to the seller.

[Overview of Information Processing System S]
1 is a diagram for explaining an overview of an information processing system S. The information processing system S is a system used for providing a commercial transaction management service for managing commercial transactions. The information processing system S has a user terminal 1, a seller terminal 2, and an information processing device 3.

The user terminal 1 (user terminal 1a and user terminal 1b in FIG. 1) is a terminal used by a user U (user U1 and user U2 in FIG. 1) who uses the commercial transaction management service, and is, for example, a smartphone, a tablet terminal, or a personal computer. For example, a dedicated application program (hereinafter referred to as a "dedicated app") for providing the commercial transaction management service is installed in the user terminal 1. The user U can use the commercial transaction management service by using the dedicated app. The commercial transaction management service may be provided on a website.

The seller terminal 2 is a terminal used by the seller, and is, for example, a smartphone, a tablet terminal, a personal computer, or a server. The seller is a business that sells set products in which multiple products are sold as a set. The seller terminal 2 manages information related to the set products (for example, the ID of the set product, the selling price of the set product, etc.). For example, a dedicated app is installed on the seller terminal 2.

The product is at least one of an item and a service provided by a provider. The multiple products included in the set product may be provided by the same provider, or may be provided by multiple different providers. The provider is, for example, a business operator that operates multiple stores, or a business operator that operates an independent store. The provider may be a seller, or a business operator different from the seller. The provider provides the product according to the information based on the provision token upon presentation of the provision token by the holder of the provision token. The provision token is a token issued on the blockchain in response to a customer purchasing a set product from a seller, and is a token used to provide the products included in the set product. The provision token is, for example, a non-fungible token. The information based on the provision token is, for example, the ID of the provision token, the ID of the product corresponding to the provision token, the name of the product corresponding to the provision token, etc.

The information processing device 3 is a device that manages the commercial transaction management service. The information processing device 3 may be multiple nodes that make up the blockchain, or may be an external server that is different from the nodes that make up the blockchain. The information processing device 3 manages information about the user U (e.g., the ID of the user U, etc.) and the calculation conditions.

The calculation conditions are information for calculating the compensation generated when the provision token is sold, and are, for example, information set by the seller, the provider, or the administrator of the information processing device 3. The calculation conditions are, for example, a limit value for the selling price of the provision token, a condition according to the stock number of set products, a condition according to the attributes of the provider, a condition according to the degree of utilization of blockchain, a condition according to the purchase price of the set products, a condition according to the degree of trustworthiness of the seller, etc. The compensation is, for example, the selling price at which the provision token is sold.
The processes executed by the information processing system S will be described below.

The commercial transaction management service manages the buying and selling of products (provision tokens) between multiple users U. First, when a customer, user U1, purchases a set of products from a seller, the seller provides user U1 with a provision token corresponding to the set of products. In this case, when the seller performs an operation to provide user U1 with a provision token in a dedicated app on the seller terminal 2, the seller terminal 2 sends a request for issuing the provision token ((1) in FIG. 1). The issuance request is a request to execute a process to issue a provision token to have the provider provide the product.

When the information processing device 3 acquires a request for issuing a provision token, it executes an issuance process in which it issues a provision token corresponding to some of the products included in the set product to the blockchain in association with the calculation conditions it manages and the holder of the provision token (user U1) ((2) in FIG. 1). The some of the products included in the set product may be, for example, one product or a combination of two products when the set product includes three products. When the provision token is issued in the blockchain, user U1 can use the provision token to have the product provided by the provider.

Next, when user U1 sells at least one of the multiple provision tokens corresponding to the set product to user U2, user U1 provides the provision token to user U2. In this case, when user U1 performs an operation to sell the provision token to user U2 in a dedicated app on user terminal 1a, user terminal 1a sends a sales processing request for the provision token to information processing device 3 ((3) in FIG. 1). The sales processing request is a request for user U, the seller who is the customer who purchased the set product, to execute processing to sell the provision token to user U, the purchase destination.

When the information processing device 3 acquires a sales process request for the provision token, it executes a sales process in which user U1 sells the provision token to user U2 ((4) in FIG. 1). Specifically, first, the information processing device 3 calculates the sales price of the provision token based on the calculation conditions associated with the provision token. Then, the information processing device 3 executes an asset transfer process in which assets equivalent to the calculated sales price are transferred from user U2 to user U1, and a token transfer process in which the holder of the provision token is transferred from user U1, the seller user U, to user U2, the buyer user U. The assets are, for example, crypto assets, electronic money, cash, etc.

After that, the user U2 uses the transferred provision token to have the provider provide the product. In this way, the information processing system S can provide a mechanism for restricting the sale of the provision token by the user U.
The configuration of the information processing device 3 will be described below.

[Configuration of information processing device 3]
Fig. 2 is a block diagram of the information processing device 3. In Fig. 2, the arrows indicate the main data flows, and there may be data flows other than those shown in Fig. 2. In Fig. 2, each block indicates a functional configuration, not a hardware (device) configuration. Therefore, the blocks shown in Fig. 2 may be implemented in a single device, or may be implemented separately in multiple devices. Data may be exchanged between blocks via any means, such as a data bus, a network, or a portable storage medium.

The information processing device 3 has a communication unit 31, a storage unit 32, and a control unit 33. The information processing device 3 may be configured by connecting two or more physically separate devices by wire or wirelessly. The information processing device 3 may also be configured by a cloud, which is a collection of computer resources.

The communication unit 31 has a communication controller for transmitting and receiving data to and from external devices such as the user terminal 1 and/or the seller terminal 2 via the network. The communication unit 31 notifies the control unit 33 of data received from the external device via the network. The communication unit 31 also transmits data output from the control unit 33 to the external device via the network.

The storage unit 32 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, etc. The storage unit 32 may be provided outside the information processing device 3, in which case data may be exchanged between the storage unit 32 and the control unit 33 via a network. The storage unit 32 stores in advance a program to be executed by the control unit 33. The storage unit 32 stores information about the user U (e.g., the ID of the user U, etc.), information about the seller (e.g., the ID of the seller, the ID of a set of products sold by the seller, the ID of a product included in the set of products, etc.), and information about the provider (e.g., the ID of the provider, the attributes of the provider, the ID of a product provided by the provider, etc.).

The storage unit 32 also stores a condition management database that manages the calculation conditions. FIG. 3 is a diagram showing an example of the configuration of the condition management database. In the example shown in FIG. 3, the condition management database stores the seller ID, the set product ID, and the calculation conditions in association with each other. The condition management database may further store the IDs of the products included in the set products in association with each other. Note that when the information processing device 3 is an external server, the information processing device 3 may store the information stored in the condition management database in a blockchain.

Returning to FIG. 2, the control unit 33 has an acquisition unit 331, a recording unit 332, a token management unit 333, a calculation unit 334, a transfer processing unit 335, and an output unit 336. The control unit 33 is a processor such as a CPU (Central Processing Unit), and functions as the acquisition unit 331, the recording unit 332, the token management unit 333, the calculation unit 334, the transfer processing unit 335, and the output unit 336 by executing a program stored in the memory unit 32. Below, the details of each function of the control unit 33 will be explained, divided into a provision token issuance process and a provision token sales process.

[Issue process]
First, the provision token issuance process executed by the information processing device 3 will be described. The acquisition unit 331 acquires the calculation conditions. Specifically, the acquisition unit 331 acquires the calculation conditions corresponding to the set product. The acquisition unit 331 acquires a recording request including, for example, a seller ID, a set product ID, and the calculation conditions. The acquisition unit 331 may acquire the calculation conditions corresponding to each product included in the set product. In this case, the acquisition unit 331 acquires a recording request including, for each product included in the set product, the product ID, the seller ID, the set product ID, and the calculation conditions.

The acquisition unit 331 acquires, for example, from the seller terminal 2, a recording request including the calculation conditions set by the seller. The acquisition unit 331 may also acquire a recording request including the calculation conditions set by the provider from a provider terminal (not shown) used by the provider. The acquisition unit 331 may also acquire a recording request including the calculation conditions set by an administrator of the information processing device 3 by accepting calculation conditions input by the administrator.

The recording unit 332 records the calculation conditions acquired by the acquisition unit 331. Specifically, the recording unit 332 associates the seller ID, the set product ID, and the calculation conditions included in the recording request acquired by the acquisition unit 331, and records them in the condition management database.

The token management unit 333 executes an issuance process for issuing to the blockchain a provision token corresponding to some of the products included in the set product in association with the calculation conditions stored in the storage unit 32 and the holder of the provision token. For example, the token management unit 333 executes an issuance process for issuing to the blockchain a provision token corresponding to each product included in the set product in association with the calculation conditions stored in the storage unit 32 and the holder of the provision token. Note that the token management unit 333 may execute an issuance process for issuing to the blockchain a provision token corresponding to each combination of multiple products included in the set product (for example, each combination of one product and each combination of two products, etc.) in association with the calculation conditions stored in the storage unit 32 and the holder of the provision token.

For example, if the information processing device 3 is an external server, the token management unit 333 causes the blockchain to issue a provision token by requesting the blockchain to issue a provision token. Also, for example, if the information processing device 3 is a plurality of nodes that constitute a blockchain, the token management unit 333 issues a provision token.

The token management unit 333 may execute the provision token issuance process in association with various information in addition to the calculation conditions and the holder of the provision token. For example, the token management unit 333 may execute the provision token issuance process for each product, further associating it with the ID of a set product, the ID of the product, and attribute identification information. The attribute identification information is information for identifying the attributes of the provider, such as the provider ID or information indicating the provider attributes (for example, the size of the provider, the area where the store operated by the provider is located, etc.). The token management unit 333 may execute the provision token issuance process in association with the ID of the product as provider information.

Figure 4 is a schematic diagram showing an example of the configuration of a provision token. In the example shown in Figure 4, a provision token corresponding to a certain product is associated with the provision token ID, the ID of the holder of the provision token, the ID of the set product, the ID of the product, the ID of the provider as attribute identification information, the calculation conditions, and the issue date and time. The issue date and time is the date and time when the provision token is issued.

In addition, information other than the ID of the provided token and the ID of the holder of the provided token may be stored in an external device. In this case, the provided token may be stored in association with the ID of the provided token, the ID of the holder of the provided token, and information indicating the location where the information other than the ID of the provided token and the ID of the holder of the provided token is stored (e.g., a URL (Uniform Resource Locator) or the like).

Returning to FIG. 2, the token management unit 333 executes a provision token issuance process when a customer purchases a set of products from a seller. Specifically, the information processing device 3 executes the following two steps to execute a provision token issuance process in response to a customer purchasing a set of products from a seller.

As a first step, the acquisition unit 331 acquires a request for issuing a provision token from the seller terminal 2. The request for issuing a provision token includes, for example, the seller ID, the ID of the set product, and the ID of the user U who purchased the set product.

In the second step, when the token management unit 333 acquires the issuance processing request acquired by the acquisition unit 331, the token management unit 333 executes the provision token issuance processing based on the information included in the issuance processing request. Specifically, for each product included in the set product, the token management unit 333 executes the provision token issuance processing by associating the provision token corresponding to the product with the calculation conditions stored in the condition management database in association with the seller ID and the set product ID included in the issuance processing request, the set product ID, the product ID, and the ID of user U included in the issuance processing request as the holder of the provision token.

In the above, an example has been described in which the token management unit 333 executes the issuance process of the provided token in association with the calculation conditions stored in the condition management database, but this is not limited to the example. For example, the issuance process request acquired by the acquisition unit 331 may further include calculation conditions, and the token management unit 333 may execute the issuance process of the provided token in association with the calculation conditions included in the issuance process request.

The token management unit 333 may execute the process of issuing the provision token depending on the trustworthiness of the seller. For example, the information about the seller stored in the memory unit 32 includes information indicating the seller (e.g., the seller's ID) and a trustworthiness number. The trustworthiness number is a number indicating the trustworthiness of the seller, and is, for example, a number calculated by a business operator that evaluates the trustworthiness of the seller, a number calculated based on the evaluation of a purchaser who purchased the seller's product, etc.

In this case, when a customer purchases a set of products from a seller, the token management unit 333 executes a process of issuing a provided token based on the reliability associated with the seller in the memory unit 32. Specifically, when the reliability associated with the seller's ID in the information about the seller exceeds the reliability threshold, the token management unit 333 executes a process of issuing a provided token in association with the calculation condition. The reliability threshold is, for example, a predetermined threshold used to determine whether the reliability of the seller is high.

On the other hand, if the reliability value associated with the seller's ID in the information about the seller does not exceed the reliability threshold, the token management unit 333 executes the process of issuing the provided token without associating it with the calculation conditions. In this way, the information processing device 3 can reduce the risk that a seller with a low reliability level will misuse the restrictions on commercial transactions between users U imposed by the commercial transaction management service.

[Sales Processing]
Next, the sales process executed by the information processing device 3 will be described. As the sales process, the information processing device 3 executes an asset transfer process for transferring assets equivalent to the sales price of the provided token, and a token transfer process for transferring the sales token from the seller user U to the buyer user U. First, the asset transfer process will be described. The information processing device 3 executes the asset transfer process by executing the following three steps.

As a first step, the acquisition unit 331 acquires a sales processing request from the user terminal 1 of the holder of the provided token, in which the seller user U who is the holder of the provided token sells the provided token to a buyer. The sales processing request includes, for example, the ID of the seller user U, the ID of the buyer user U, and the ID of the provided token. The sales processing request may further include the ID of a set product.

In a second step, when the acquisition unit 331 acquires a sales processing request, the calculation unit 334 calculates the selling price of the provided token based on the calculation conditions associated with the provided token in the blockchain. Specifically, the calculation unit 334 calculates the selling price of the provided token based on the calculation conditions associated with the provided token identified by the ID of the provided token included in the sales processing request in the blockchain.

The calculation unit 334 calculates the selling price of the provided token based on, for example, the number of set products in stock. Specifically, when the calculation conditions include a condition for calculating the selling price of the provided token based on the number of set products in stock at the seller, the calculation unit 334 calculates the selling price of the provided token based on the number of set products in stock at the time of selling the provided token.

For example, the calculation conditions include an inventory threshold for determining whether the inventory of set products is large or not, as a condition for calculating the selling price of the provided token according to the inventory quantity of set products at the seller. Also, for example, the memory unit 32 stores a first inventory value used when the inventory quantity of set products is large, and a second inventory value used when the inventory quantity of set products is small.

The first stock number and the second stock number are different numbers, and are, for example, coefficients applied to the sales price of the set product at a predetermined point in time (for example, the point in time when the set product is purchased or the point in time when the provision token is sold, etc.). The first stock number and the second stock number are, for example, numbers set by the seller, the provider, or the administrator of the information processing device 3. The first stock number and the second stock number may be common numbers for each set product, or may be different numbers for each set product. When the first stock number and the second stock number are applied to the sales price of the set product, the sales price of the provision token is lower for the first stock number than for the second stock number. Note that when the first stock number and the second stock number are applied to the sales price of the set product, the sales price of the provision token may be lower for the second stock number than for the first stock number.

In this case, the calculation unit 334 first obtains information from the seller terminal 2 indicating the current inventory quantity of the set products and the selling price of the set products at a specified time. Then, when the inventory quantity of the set products exceeds the inventory quantity threshold included in the calculation conditions, the calculation unit 334 calculates the selling price of the provided token by multiplying the selling price of the set products at the specified time by the first inventory value stored in the memory unit 32. On the other hand, when the inventory quantity of the set products does not exceed the inventory quantity threshold included in the calculation conditions, the calculation unit 334 calculates the selling price of the provided token by multiplying the selling price of the set products at the specified time by the second inventory value stored in the memory unit 32. In this way, the information processing device 3 can calculate the selling price of the provided token according to the value of the set products (the inventory quantity of the set products) at the time of selling the provided token.

The calculation unit 334 may calculate the sales price of the provision token according to the market trading price of the set product. The market trading price may be, for example, the sales price of the set product sold by the seller who sold the set product, or a statistical value (e.g., average, median, mode, etc.) of the sales prices of the set product sold by multiple different sellers, or the cheapest sales price among the sales prices of the set product sold by each of the multiple sellers.

Specifically, when the calculation conditions include a condition for calculating the selling price of the provided token based on the market trading price of the set product at the seller, the calculation unit 334 calculates the selling price of the provided token based on the market trading price of the set product at the seller. More specifically, the calculation unit 334 calculates the selling price of the provided token based on the relationship between the purchase price of the set product purchased by the customer and the market trading price of the set product at the seller. For example, the memory unit 32 stores a first market trading figure that is used when the market trading price of the set product is high, and a second market trading figure that is used when the market trading price of the set product is low.

The first market trading number and the second market trading number are different numbers, and are, for example, coefficients applied to the selling price of the set products at a specified point in time. The first market trading number and the second market trading number are, for example, numbers set by the seller, the provider, or the administrator of the information processing device 3. The first market trading number and the second market trading number may be common numbers for each set product, or may be different numbers for each set product. The first market trading number and the second market trading number may be such that the selling price of the provided token when applied to the selling price of the set product is lower for the first market trading number than the second market trading number, or lower for the second market trading number than the first market trading number.

In this case, the calculation unit 334 first obtains from the seller terminal 2 information indicating the current market trading price of the set products and the sales price of the set products when the customer purchased the set products (e.g., the date and time of issuance of the provision token). Note that the memory unit 32 stores information indicating the current market trading price of the set products and the sales price of the set products when the customer purchased the set products, and the calculation unit 334 may obtain from the memory unit 32 information indicating the current market trading price of the set products and the sales price of the set products when the customer purchased the set products.

Then, if the current market trading price of the set products exceeds the selling price of the set products when the customer purchased them, the calculation unit 334 calculates the selling price of the provided token by multiplying the selling price of the set products at the specified time by the first market trading numerical value stored in the memory unit 32. On the other hand, if the current market trading price of the set products does not exceed the selling price of the set products when the customer purchased them, the calculation unit 334 calculates the selling price of the provided token by multiplying the selling price of the set products at the specified time by the second market trading numerical value stored in the memory unit 32. In this way, the information processing device 3 can calculate the selling price of the provided token according to the value of the set products.

The calculation unit 334 may calculate the selling price of the provided token according to the attributes of the provider. The attributes of the provider include, for example, the management type of the provider (e.g., an individual store, a franchise chain, etc.), the number of stores operated by the provider, the area in which the stores operated by the provider are located, etc.

Specifically, when the calculation conditions include a condition for calculating the selling price of the provided token according to the attributes of the provider, the calculation unit 334 calculates the selling price of the provided token based on the attributes of the provider identified by the attribute identification information associated with the provided token.

The calculation unit 334, for example, refers to information about the provider stored in the memory unit 32, and calculates a higher sales price for the provided token when the provider identified by the provider ID (attribute identification information) associated with the provided token is managed as a franchise chain than when the provider is managed as an individual store. The calculation unit 334 may also calculate a higher sales price for the provided token the more stores the provider manages, and calculate a lower sales price for the provided token the fewer stores the provider manages. The calculation unit 334 may also calculate a higher sales price for the provided token the more regions in which the provider manages its stores, and calculate a lower sales price for the provided token the fewer regions in which the provider manages its stores. In this way, the information processing device 3 can calculate the sales price of the provided token according to the attributes of the provider.

The calculation unit 334 may calculate the selling price of the provided token according to the trustworthiness of the seller. In this case, when the calculation conditions include a condition for calculating the selling price of the provided token according to the trustworthiness of the seller, the calculation unit 334 calculates the selling price of the provided token based on the trustworthiness of the seller. For example, the calculation unit 334 calculates a higher selling price of the provided token the higher the trustworthiness of the seller, and calculates a lower selling price of the provided token the lower the trustworthiness of the seller. For example, when the trustworthiness number associated with the seller in the memory unit 32 exceeds a trust threshold, the calculation unit 334 calculates a higher selling price of the provided token than when the trustworthiness number does not exceed the trust threshold. In this way, the information processing device 3 can calculate the selling price of the provided token according to the trustworthiness of the seller.

The calculation unit 334 may calculate the selling price of the provision token according to the degree of usage of the blockchain on which the provision token was issued. For example, the storage unit 32 stores information indicating the blockchain in association with information for identifying the degree of usage of the blockchain (e.g., the number of users using the blockchain, the number of tokens issued in the blockchain, etc.).

In this case, if the calculation conditions include a condition for calculating the selling price of the provided token according to the degree of utilization of the blockchain on which the provided token was issued, the calculation unit 334 calculates the selling price of the provided token based on the degree of utilization of the blockchain on which the provided token was issued. For example, the calculation unit 334 calculates a higher selling price for the provided token the higher the degree of utilization of the blockchain on which the provided token was issued, and calculates a lower selling price for the provided token the lower the degree of utilization of the blockchain. In this way, the information processing device 3 can calculate the selling price of the provided token according to the degree of utilization of the blockchain on which the provided token was issued.

The calculation unit 334 may calculate the selling price of the provided token according to the limit value of the selling price of the provided token. For example, the calculation conditions include at least one of the upper limit value of the selling price of the provided token and the lower limit value of the selling price of the provided token as the limit value of the selling price of the provided token.

In this case, if the calculation conditions include an upper limit value, the calculation unit 334 calculates the selling price of the provided token so that it does not exceed the upper limit value. For example, if the calculated selling price of the provided token exceeds the upper limit value included in the calculation conditions, the calculation unit 334 calculates the upper limit value as the selling price of the provided token. Note that the sales process request includes a set price set by the holder of the provided token as the price at which the provided token is sold, and if the set price exceeds the upper limit value included in the calculation conditions, the calculation unit 334 may calculate the upper limit value as the selling price of the provided token.

When the calculation conditions include a lower limit, the calculation unit 334 calculates the selling price of the provided token so that it does not fall below the lower limit. For example, when the calculated selling price of the provided token falls below an adjustment value included in the calculation conditions, the calculation unit 334 calculates the lower limit as the selling price of the provided token. Note that the sales processing request includes a set price of the provided token, and when the set price falls below a lower limit included in the calculation conditions, the calculation unit 334 may calculate the lower limit as the selling price of the provided token. In this way, the information processing device 3 can calculate the selling price of the provided token so as to satisfy the set selling price limit.

The calculation unit 334 may calculate the sales price of the provided token according to a limit value of the total amount of the sales price of the provided token corresponding to each of the multiple products included in the set product (hereinafter referred to as the "total amount corresponding to the set product"). For example, the calculation conditions include at least one of an upper limit value of the total amount corresponding to the set product and a lower limit value of the total amount corresponding to the set product as the limit value of the sales price of the provided token.

In this case, the calculation unit 334 first identifies, in the blockchain, multiple provision tokens that have been issued in association with the ID of the seller user U (ID of the holder of the provision token) included in the sales processing request and the ID of the set product. The calculation unit 334 then calculates the sales price of the identified multiple provision tokens so as to satisfy the limit value of the total amount corresponding to the set product.

For example, when the calculation conditions include an upper limit value, the calculation unit 334 calculates the selling price of the identified multiple provision tokens so that the total amount of the selling price of the identified multiple provision tokens does not exceed the upper limit value. Also, when the calculation conditions include a lower limit value, the calculation unit 334 calculates the selling price of the identified multiple provision tokens so that the total amount of the selling price of the identified multiple provision tokens does not fall below the lower limit value.

After calculating the sales prices of the identified multiple provision tokens, the calculation unit 334 associates the ID of each provision token with the sales price of each provision token and stores them in the memory unit 32. After calculating the sales prices of the identified multiple provision tokens, if the acquisition unit 331 acquires a sales processing request for the identified provision tokens, the calculation unit 334 uses the sales price stored in the memory unit 32 in association with the ID of the provision token included in the sales processing request. In this way, the information processing device 3 can calculate the sales price of the provision tokens so as to satisfy the limit value of the total amount corresponding to the specified set of products.

A user U who has purchased a set product may sell multiple provision tokens together, rather than selling one provision token at a time. In this case, the calculation unit 334 may calculate the set sales price of the set provision tokens according to a limit value of the set sales price, which is the sales price of the set provision token, which is the combined multiple provision tokens. A set provision token is a set of multiple provision tokens corresponding to multiple products that are part of all the products included in the set product, for example, a combination of two products when a set product includes three products. For example, the calculation conditions include at least one of the upper limit value of the set sales price of the set provision tokens and the lower limit value of the set sales price of the set provision tokens as the limit value of the set sales price of the set provision tokens.

In this case, if the calculation conditions include an upper limit value, the calculation unit 334 calculates the set sales price of the set provision token so that it does not exceed the upper limit value. For example, if the calculated set sales price of the set provision token exceeds the upper limit value included in the calculation conditions, the calculation unit 334 calculates the upper limit value as the set sales price of the set provision token. Note that, if multiple products that are part of all the products included in the set product are sold, the information processing device 3 may newly issue a set provision token bundling the multiple products, and calculate the sales price of the set provision token based on the calculation conditions associated with the issued set provision token.

When the calculation conditions include a lower limit value, the calculation unit 334 calculates the set sales price of the set provision token so that it does not fall below the lower limit value. For example, when the calculated set sales price of the set provision token falls below an adjustment value included in the calculation conditions, the calculation unit 334 calculates the lower limit value as the set sales price of the set provision token. In this way, the information processing device 3 can calculate the set sales price of the set provision token so as to satisfy the set sales price limit value.

The calculation unit 334 may calculate the sales price of the provision token according to the sales price of the set merchandise when the customer purchases the set merchandise. Specifically, when the calculation conditions include a condition for calculating the sales price of the provision token according to the sales price of the set merchandise when the customer purchases the set merchandise, the calculation unit 334 calculates the sales price of the provision token so that it does not exceed the sales price. For example, when the calculated sales price of the provision token exceeds the sales price, the calculation unit 334 calculates the sales price as the sales price of the provision token. In this way, the information processing device 3 can prevent a situation in which the sales price of the provision token exceeds the sales price of the set merchandise when the customer purchases the set merchandise.

As a third step, the transfer processing unit 335 executes an asset transfer process to transfer assets equivalent to the selling price of the provided token calculated by the calculation unit 334 from the destination user U to the seller user U. For example, the information processing device 3 manages the account of user U's assets in association with the ID of user U. In this case, the transfer processing unit 335 transfers assets equivalent to the selling price of the provided token calculated by the calculation unit 334 from the account associated with the destination user U's ID included in the sales processing request to the account associated with the seller user U's ID included in the sales processing request.

When an account management device (not shown) manages the account of user U's assets, the transfer processing unit 335 may execute the asset transfer process by sending an asset transfer request to the account management device to transfer assets equivalent to the sales price of the provision token calculated by the calculation unit 334 from the account of the buyer user U to the account of the seller user U, the asset transfer request including the ID of the seller user U and the ID of the buyer user U.

Before the provision token is sold, the information processing device 3 may present the selling price at which the provision token will be sold. Specifically, first, the acquisition unit 331 acquires a viewing request to view the selling price of the provision token from the user terminal 1 of the seller user U or the sold user U (hereinafter referred to as the "requester"). The viewing request includes, for example, the ID of the provision token.

In response to the viewing request acquired by the acquisition unit 331, the calculation unit 334 calculates the selling price of the provided token based on the calculation conditions associated with the provided token indicated by the ID of the provided token included in the viewing request. The output unit 336 then presents the selling price of the provided token calculated by the calculation unit 334 to the requester, i.e., outputs it to the user terminal 1 of the requester. In this way, the information processing device 3 can allow the requester to recognize in advance the price at which the provided token can be sold.

In the above, an example was described in which the consideration is the selling price of the provision token, but this is not limited to this. For example, the consideration may be a refund amount refunded to a specified business operator when the provision token is sold. The specified business operator is, for example, a seller, a provider that provides a product based on the provision token being sold, or another provider that provides a product based on a provision token other than the provision token being sold among the provision tokens corresponding to each of the multiple products included in the set product. For example, the calculation conditions include information indicating the specified business operator to which the refund amount is refunded.

In this case, first, the calculation unit 334 calculates the refund amount based on the calculation conditions associated with the provided token in the blockchain in response to a sales processing request from the seller user U, who is a customer, to sell the provided token to the seller user U. Then, the transfer processing unit 335 executes processing to transfer assets equivalent to the refund amount calculated by the calculation unit 334 to a specified business operator included in the calculation conditions.

The transfer processing unit 335 executes a process for transferring assets equivalent to the refund amount calculated by the calculation unit 334 from the account of the seller user U or the account of the buyer user U to the account of a specified business operator, for example. The transfer processing unit 335 may execute a process for transferring assets equivalent to the refund amount calculated by the calculation unit 334 from the account of the seller user U to the account of a specified business operator, which is part of the sales price of the provision token. The transfer processing unit 335 may execute a process for transferring assets equivalent to the refund amount calculated by the calculation unit 334 from the account of the administrator who manages the information processing device 3 to the account of the specified business operator. In this way, the information processing device 3 can reduce the disadvantage that the business operator may suffer when the provision token is sold. For example, the sales price of a set product may be lower than the total amount of the sales prices of multiple products included in the set product. In this case, when a customer sells a set product in parts, the refund amount is refunded to the business operator who has borne the difference between the sales price of the set product and the total amount of the sales prices of multiple products included in the set product, thereby reducing the financial burden of the business operator.

Next, the token transfer process will be described. The information processing device 3 executes the token transfer process to transfer the sales token from the seller user U to the destination user U.

Specifically, as a token transfer process, the token management unit 333 executes a process for changing the holder of the provided token from the seller user U to the sold user U. More specifically, the token management unit 333 executes a process for changing the holder of the provided token identified by the ID of the provided token included in the sales processing request from the ID of the seller user U included in the sales processing request to the ID of the sold user U included in the sales processing request.

Although an example in which the information processing device 3 executes the sales process has been described above, this is not limiting. For example, if the information processing device 3 is an external server, the information processing device 3 may cause the blockchain to execute the sales process by transmitting a sales process request from the user terminal 1 of the holder of the provided token to the blockchain. In addition, the blockchain may execute the sales process in response to a sales process request from the user terminal 1 of the holder of the provided token by a smart contract, without going through the information processing device 3. When the blockchain executes the sales process, the information processing device 3 may obtain the execution result of the sales process executed by the blockchain (for example, the calculated sales price of the provided token, etc.).

[Processing of information processing device 3]
Next, a description will be given of the flow of processing executed by the information processing device 3. Fig. 5 is a flowchart showing the flow of processing executed by the information processing device 3. This flowchart starts when the acquisition unit 331 acquires a request for processing to issue a provision token from the seller terminal 2 (S1).

The token management unit 333 executes the provision token issuance process by associating the provision token corresponding to each product included in the set product with the calculation conditions stored in the condition management database in association with the seller ID and the set product ID included in the issuance process request, the set product ID, the product ID, and the ID of user U included in the issuance process request as the holder of the provision token (S2).

The acquisition unit 331 acquires a sales processing request from the user terminal 1 of the holder of the provided token, in which the seller user U, who is the holder of the provided token, sells the provided token to the buyer user U (S3). The calculation unit 334 calculates the sales price of the provided token based on the calculation conditions associated with the provided token identified in the blockchain by the ID of the provided token included in the sales processing request (S4).

The transfer processing unit 335 executes an asset transfer process to transfer assets equivalent to the selling price of the provided token calculated by the calculation unit 334 from the destination user U to the seller user U (S5). The token management unit 333 executes a token transfer process to transfer the holder of the provided token from the seller user U to the destination user U (S6).
