Description

The present invention relates to an information processing device, an information processing method, and a program for processing information about crypto assets.

Patent Literature 1 describes a system for settlement with crypto assets (also referred to as virtual currency).

Japanese Patent Application Laid-Open No. 2018-77640

Crypto assets that can be used for settlement are issued for the purpose of activating economic circulation. However, even if the issued cryptographic asset is paid, the user may not use the cryptographic asset immediately. There was a problem that the economic cycle would not be activated if the crypto-assets were not used.

Therefore, the present invention has been made in view of these points, and an object thereof is to provide an information processing device, an information processing method, and a program that can promote the use of crypto assets.

An information processing apparatus according to a first aspect of the present invention includes a transfer management unit that manages the transfer of crypto assets circulating in a predetermined area, and a transfer management unit that reduces the balance of the crypto assets deposited in a user account. It has a storage unit that stores a reduction condition, and an updating unit that reduces the balance of the crypto assets that satisfy the reduction condition among the crypto assets deposited in the account of the user.

The reduction condition may include a condition related to a holding period of the crypto-assets, and the updating unit may include a period from when the crypto-assets were deposited in the account of the user in the reduction conditions. The balance of crypto assets that meet the holding period conditions may be decreased.

The reduction condition may include a condition regarding the number of transfers of the crypto-assets, and the update unit may include the number of transfers of the crypto-assets deposited in the account of the user in the reduction conditions. The balance of the crypto asset that satisfies the condition regarding the number of transfers may be decreased.

The information processing device may further include a condition management unit that acquires the reduction condition from a fund bearer who has borne the funds for issuing the crypto asset, and stores the condition in the storage unit.

The transfer management unit may transfer the cryptographic assets corresponding to the payment from the user's account to the other user's account in response to a payment request for payment of the payment by the user to another user. .

The information processing device, in response to a request from a source bearer who has borne the source funds for issuing the crypto assets, a first asset corresponding to the amount borne by the source bearer, and a first asset corresponding to the burden amount and an issuing unit that issues the cryptographic asset including the second asset to be added to the cryptographic asset, and deposits the first asset and the second asset included in the issued cryptographic asset into the account of the user. Alternatively, the updating unit may reduce the second asset out of the first asset and the second asset included in the crypto assets deposited in the account of the user.

When the information processing device converts the crypto asset into a predetermined currency in response to a request from a user, when converting the first asset, the amount equivalent to the first asset to be converted is the source of funds. In the case where the second asset is converted into money by making a person bear the cost, the liquid conversion unit may further include a money conversion unit that makes the business operator who manages payment bear the amount of money equivalent to the second asset to be converted into money.

The update unit may decrease the balance of the crypto assets deposited in the user's account.
The transfer management unit may transfer the crypto-assets reduced by the update unit to an account of a source bearer who has borne the funds for issuing the crypto-assets.

[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 crypto-asset management system 1 , a settlement server 2 and a user terminal 3 . The information processing system S may include devices such as other servers and terminals.

The crypto-asset management system 1 (information processing device) is one or more computers for managing information about crypto-assets distributed in a predetermined area. Crypto assets can be used for payment and the like, and are electronic assets different from legal currencies (Japanese yen, US dollar, etc.). Crypto assets may be electronic assets backed by legal currency, such as electronic assets having the same value and guarantee as legal currency, and may be stable coins or digital currencies. A crypto asset can be converted into a predetermined currency at a predetermined conversion ratio. A crypto asset is associated with a user who holds the crypto asset in, for example, a storage device, and is transferred from a user who is a customer to a user who is a store 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.

A crypto asset may be a regional digital currency available in a given region. For example, settlement 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.

A crypto asset may be a local digital currency available to a given user. For example, settlement using crypto assets, which is a regional digital currency, can be executed at a store within a predetermined region in response to a request from a predetermined user; And it cannot be executed at stores inside and outside the area in response to a request from a user other than the predetermined user. In a predetermined area and a predetermined user, for example, it is determined by the person who bears the funds of the crypto assets. The source bearer is a person who bears the source of funds for issuing the crypto-assets, such as a local government or a business operator that provides a predetermined service to users.

The crypto-asset management system 1 manages the crypto-asset owned by each user in the crypto-asset account associated with the user. The crypto-asset management system 1 transfers crypto-asset from one user's crypto-asset account to another user's crypto-asset account, for example, in response to a transfer request received from the settlement server 2 . The crypto-asset management system 1 can communicate with the payment server 2 and the user terminal 3 via a network.

The settlement server 2 is a computer for making payments using crypto assets. For example, in response to receiving a payment request from the user terminal 3, the payment server 2 issues a transfer request to the crypto-asset management system 1 to transfer the crypto-asset corresponding to the amount to be settled from one user to another user. to send. The settlement server 2 can communicate with the crypto-asset management system 1 and the user terminal 3 via a network.

The user terminal 3 is a computer used by a user. A user is, for example, a customer who pays for a product (goods, service, etc.) to another user, who is a store, using crypto assets. Also, the user may be a store that pays another user, who is a store, using crypto assets. The user terminal 3 is, for example, a smart phone, a tablet terminal, or a personal computer. The user terminal 3 has an operation unit such as a touch panel or keyboard for receiving operations, a display unit such as a liquid crystal display for displaying information, and an imaging unit such as a camera for reading information. The user terminal 3 can communicate with the settlement server 2 via a network.

The information processing system S reduces the balance of the crypto assets that satisfy the reduction conditions among the crypto assets deposited in the crypto asset accounts of each user. The decrease condition is a condition for decreasing the balance of the crypto assets deposited in the user's crypto asset account, for example, at least one of the conditions regarding the retention period of the crypto assets and the conditions regarding the number of transfers of the crypto assets. or

The number of transfers of crypto-assets differs for each user's crypto-asset account. For crypto assets, it is desirable that the number of transfers is large in order to activate the economic cycle. Therefore, the information processing system S reduces the balance of the crypto-assets by setting the amount of decrease when the number of transfers of the crypto-assets is large to be less than the amount of decrease when the number of transfers of the crypto-assets is small.

By doing so, the information processing system S can provide the user with motivation to use the crypto-assets before the balance of the crypto-assets is reduced. Thereby, the information processing system S can promote the use of crypto assets. As a result, the information processing system S can activate economic circulation through the use of crypto assets.
The configuration of the crypto-asset management system 1 will be described below.

[Configuration of crypto-asset management system 1]
FIG. 2 is a block diagram of the crypto-asset management system 1 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 crypto-asset management system 1 may be configured by connecting two or more physically separated devices by wire or wirelessly. Also, the crypto-asset management system 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 between the payment server 2 and the user terminal 3 via the network. The communication unit 11 notifies the control unit 13 of data received from the payment server 2 or the user terminal 3 via the network. The communication unit 11 also transmits data output from the control unit 13 to the payment server 2 or the user terminal 3 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. The storage unit 12 may be provided outside the crypto-asset management system 1, in which case data may be exchanged with the control unit 13 via a network.

The control unit 13 has an issuing unit 131 , a money conversion unit 132 , a transfer management unit 133 , a condition management unit 134 , an update unit 135 and a notification unit 136 . The control unit 13 is a processor such as a CPU (Central Processing Unit), for example. It functions as an update unit 135 and a notification unit 136 . Processing performed by the issuing unit 131, the money conversion unit 132, the transfer management unit 133, the condition management unit 134, the update unit 135, and the notification unit 136 will be described later.

[Description of account]
First, a method for managing crypto assets 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.

The crypto-asset management system 1 manages crypto-assets held by each of a plurality of users in crypto-asset accounts. Each crypto-asset account of a plurality of users is associated with the user's identification (ID), eg, the ID of the crypto-asset account. The crypto-asset management system 1 manages crypto-assets by depositing and withdrawing crypto-assets to and from crypto-asset accounts, or transferring crypto-assets between a plurality of crypto-asset accounts.

The crypto-asset management system 1 manages crypto-assets using a coin as an asset unit, for example, using blockchain. The crypto-asset management system 1 stores, for example, a block (data) that associates a user's ID with transaction details in the user's crypto-asset account as a block chain on one or more storage devices on the network. do. 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 crypto-asset management system 1 is not limited to blockchain, and for example, data that associates a user's ID, the balance of the user's crypto-asset account, and the content of one or more transactions in the user's crypto-asset account. may be stored in the storage unit 12 as a database.

The crypto-asset management system 1 issues crypto-asset and deposits the issued crypto-asset into the user's crypto-asset account as crypto-asset management. Specifically, first, the issuing unit 131 issues cryptographic assets in response to an issuance request from the source of funds. An issuance request is a request to issue a crypto-asset, and includes, for example, the amount of crypto-asset to be issued and the ID of the user associated with the crypto-asset account into which the crypto-asset is deposited. The issuing unit 131 then issues the requested amount of cryptographic assets, and deposits the issued cryptographic assets into the user's cryptographic asset account indicated by the user's ID.

The issuing unit 131 may issue cryptocurrency on top of it. Specifically, first, the issuing unit 131 issues a crypto asset including a first asset and a second asset in response to an issuance request from the source bearer. The first asset is a crypto asset corresponding to the amount borne by the person responsible for the original funds. The second asset is a crypto asset that is added according to the amount borne by the person who bears the original funds. For example, the crypto-asset management system 1 has a predetermined add-on rate, and the issuing unit 131 calculates the amount of the second asset by multiplying the amount of the first asset by the add-on rate, and includes it in the issuance request. and a cryptographic asset containing the calculated amount of the first asset and the calculated amount of the second asset.

Then, the issuing unit 131 deposits the first asset and the second asset included in the issued crypto-asset into the user's crypto-asset account. By doing so, the crypto-asset management system 1 can provide users with many crypto-assets.

The crypto-asset management system 1 converts the crypto-asset into a predetermined currency as crypto-asset management. Specifically, the money conversion unit 132 converts the crypto asset into a predetermined currency in response to a money conversion request from the user. The conversion request is a request for converting the crypto-assets into a predetermined currency, and includes, for example, the user's ID and the amount of the crypto-assets to be converted.

The money conversion unit 132 may cause a person corresponding to the type of crypto-asset requested by the user to pay for the money involved in converting the crypto-asset into a predetermined currency. For example, the redemption request further includes information indicating the type of crypto asset selected by the user.

In this case, when the first asset is converted into money, the conversion unit 132 makes the fund bearer bear the amount corresponding to the first asset to be converted into money. On the other hand, when converting the second asset into cash, the cash conversion unit 132 causes the settlement operator to bear the amount corresponding to the second asset to be converted into cash. A payment business operator is a business operator that manages payment. By doing so, the crypto-asset management system 1 can cause the person corresponding to the type of crypto-asset requested by the user to pay for the amount of money involved in converting the crypto-asset into a predetermined currency. can.

[Description of transfer process]
Next, the configuration for the information processing system S to execute the process of transferring crypto assets will be described below. The settlement server 2 receives a settlement request for settlement of crypto assets from the user terminal 3 . The settlement request is a request for settlement of the amount to be paid by the first user to the second user, specifically, from the crypto-asset account associated with the first user to the crypto-asset account associated with the second user. This is a request for causing the crypto-asset management system 1 to transfer the settlement amount. The payment request includes, for example, the ID of the first user, the ID of the second user, and the payment amount.

Specifically, first, the user terminal 3 transmits a payment request to the payment server 2 . For example, the user terminal 3 acquires the ID of the second user by reading the QR (Quick Response) code (registered trademark) presented by the second user, and the ID of the first user associated with the user terminal 3 Then, a payment request including the acquired ID of the second user and the amount of money to be settled by the crypto asset entered by the first user is transmitted to the payment server 2 . The payment server 2 then acquires a payment request from the user terminal 3 .

Upon receiving the payment request, the payment server 2 transfers the crypto assets owned by the first user to the second user. Specifically, the settlement server 2 provides the crypto-asset management system 1 with an instruction to transfer the settlement amount from the crypto-asset account associated with the first user to the crypto-asset account associated with the second user. By notifying the transfer request, the crypto assets held by the first user are transferred to the second user. The transfer request includes the ID of the first user, the ID of the second user, and the settlement amount.

In the crypto-asset management system 1, the transfer management unit 133 manages the transfer of crypto-asset. Specifically, the transfer management unit 133 transfers the crypto-asset corresponding to the payment from the first user's crypto-asset account to the second user's crypto-asset account in response to the settlement request from the user terminal 3 . More specifically, when the transfer management unit 133 acquires a transfer request from the payment server 2 that has received the payment request, the transfer management unit 133 transfers the crypto assets corresponding to the payment amount included in the transfer request to the first Transfer from the first user's crypto-asset account identified by the user's ID to the second user's crypto-asset account identified by the second user's ID included in the transfer request.

For example, when crypto assets are managed using a blockchain, the transfer management unit 133 instructs the blockchain to change the holder of the coin corresponding to the settlement amount from the first user to the second user. Add a block to show Further, for example, when the crypto-assets are managed using a database, the transfer management unit 133 subtracts coins corresponding to the settlement amount from the first user's crypto-asset account in the database, Coins corresponding to the settlement amount may be added to the account.

The transfer management unit 133 may preferentially transfer crypto assets that have been transferred less frequently. Specifically, first, the transfer management unit 133 identifies the number of transfers that have occurred in the past for each asset unit, which is a unit in which cryptographic assets are distributed.

For example, when the crypto-asset management system 1 manages crypto-assets using a blockchain, the transfer management unit 133 refers to the transaction stored in the blockchain for each asset unit, and transfers the asset unit. Identify the number of times. For example, when the crypto-asset management system 1 manages crypto-assets using a database, the transfer management unit 133 refers to the crypto-asset transfer history stored in the database for each asset unit, and Identify the number of unit transfers.

Then, the transfer management unit 133 preferentially transfers a cryptographic unit with a relatively small number of transfers among the cryptographic assets owned by the first user. For example, the transfer management unit 133 transfers the crypto-asset unit with the least number of transfers among the crypto-asset held by the first user. By doing so, the crypto-asset management system 1 can reduce variations in the number of transfers.

The transfer management unit 133 determines whether or not the second user satisfies the conditions for permission to use the crypto-assets, and if it is determined that the second user satisfies the conditions for permission to use the crypto-assets, the transfer management unit 133 Assets may be transferred to a second user. The conditions for permitting use are conditions for permitting the use of the crypto-assets, for which the conditions under which the use of the crypto-assets is permitted with respect to the payment of the price are defined. Whether or not the area allows the use of crypto assets, or whether or not the store allows the use of crypto assets. The usage permission condition may be whether or not the second user has a crypto asset account. Note that the settlement server 2 may determine whether or not the second user satisfies the conditions for permission to use the crypto-asset, and notify the crypto-asset management system 1 of the determination result.

The transfer management unit 133 determines whether or not the first user satisfies the payment conditions, and if it is determined that the first user satisfies the payment conditions, transfers the crypto assets held by the first user to the second user. may The payment condition is a condition for the source user to pay the price with the crypto assets, for example, whether or not the first user is a user who can use the crypto assets. The transfer management unit 133, for example, determines whether or not the first user's cryptocurrency account exists, and based on the determination result, determines whether or not the first user satisfies the payment conditions.

If the transfer management unit 133 determines that the second user does not satisfy the conditions for permitting the use of the crypto assets, or if it determines that the first user does not satisfy the payment conditions, the transfer management unit 133 notifies the settlement server 2 that the crypto assets cannot be used. may be notified to the user terminal 3 via

[Description of update process]
Next, a configuration for the information processing system S to execute processing for updating the balance of the crypto assets deposited in the user's crypto asset account will be described below. In the crypto-asset management system 1, the updating unit 135 decreases the balance of the crypto-asset deposited in each user's crypto-asset account based on the decrease condition.

The reduction condition is, for example, a condition determined by the person who bears the original funds. Specifically, first, the condition management unit 134 acquires information indicating the reduction condition from the fund bearer (not shown terminal used by the fund bearer). Then, the condition management unit 134 causes the storage unit 12 to store the acquired decrease condition.

The updating unit 135 reduces the balance of crypto assets that satisfy the reduction conditions among the crypto assets deposited in the crypto asset account of each user. It is assumed that a reduction start period until the start of reduction of the balance of the crypto-assets is defined as a condition regarding the holding period of the crypto-assets included in the reduction conditions. In this case, the updating unit 135 updates crypto-assets whose holding period after the crypto-assets are deposited in the user's crypto-asset account satisfies the reduction condition, i.e., crypto-assets whose holding period has passed the reduction start period. Decrease balance.

Specifically, the updating unit 135 identifies the holding period of the crypto-asset for each user's crypto-asset account, and determines whether the specified holding period of the crypto-assets deposited in the crypto-asset account of each user satisfies the reduction condition. Decrease the balance of the crypto assets that meet. For example, when the crypto-asset management system 1 manages crypto-asset using a blockchain, the updating unit 135 refers to the transaction stored in the blockchain to identify the holding period for each asset unit. For example, when the crypto-asset management system 1 manages the crypto-asset using a database, the transfer management unit 133 refers to the crypto-asset transfer history stored in the database for each asset unit, and determines the holding period. identify. For example, if the reduction condition is one week, the updating unit 135 reduces the balance of crypto assets that have been held for one week, among the crypto assets deposited in the crypto asset account of each user.

It is assumed that a condition regarding the number of transfers of cryptographic assets included in the reduction condition is a set number of times that is set to determine the target of the cryptographic assets whose balance is to be reduced. In this case, the updating unit 135 reduces the balance of crypto-assets that satisfy the reduction condition for the number of transfers of the crypto-assets deposited in the user's crypto-asset account, that is, the balance of the crypto-assets for which the number of transfers of the crypto-assets is equal to or less than the set number of transfers. Let

Specifically, first, the updating unit 135 identifies the number of crypto-asset transfers for each user's crypto-asset account based on the transfer history of crypto-asset transfers between users. For example, when the crypto-asset management system 1 manages crypto-asset using a blockchain, the updating unit 135 refers to transactions stored in the blockchain to specify the number of transfers of the crypto-asset. Further, for example, when the crypto-asset management system 1 manages the crypto-asset using a database, the updating unit 135 refers to the transfer history of the crypto-asset in the database to identify the number of transfers of the crypto-asset.

Then, the updating unit 135 reduces the balance of the crypto-asset that satisfies the decrease condition for the specified number of transfers among the crypto-asset deposited in the crypto-asset account of each user. For example, when the set number of times defined as the decrease condition is 0, the update unit 135 determines the number of transfers of crypto-assets that have been transferred 0 times or less among the crypto-assets deposited in the crypto-asset accounts of each user. Decrease balance.

The update unit 135 sets the amount of decrease when the number of transfers of cryptographic assets specified by the transfer history of transfers of cryptographic assets between users is large to be less than the amount of decrease when the number of transfers is small. For example, the update unit 135 increases the decrease in the balance of the crypto-asset as the number of transfers of the crypto-asset decreases, and decreases the decrease in the balance of the crypto-asset as the number of transfers of the crypto-asset increases.

For example, the update unit 135 reduces the number of crypto-asset transfers that meet the reduction condition (for example, crypto-assets with zero transfers), and reduces the number of crypto-assets that do not satisfy the reduction condition (for example, , crypto assets with one or more transfers) are prohibited. For example, for a crypto-asset that satisfies a reduction condition for the number of transfers of the crypto-asset (for example, a crypto-asset whose number of transfers is less than three), the update unit 135 determines that the fewer the number of transfers of the crypto-asset (for example, If the number of transfers is 1), increase the amount of decrease in the balance of crypto assets It can be less.

For example, the updating unit 135 decreases the balance of crypto assets that satisfy both a first decrease condition that defines a decrease start period and a second decrease condition that defines a set number of times. FIG. 4 is a diagram schematically showing the transfer of crypto-assets. In the example shown in FIG. 4(a), 1,000 crypto-asset coins are issued in response to an issuance request from the source of funds, and the issued 1,000 coins are deposited in the first user's crypto-asset account.

In this case, the update unit 135 determines whether or not the holding period after the 1,000 coins deposited in the crypto asset account of the first user has passed the decrease start period. Then, when the update unit 135 determines that the holding period after the issuance of 1,000 coins deposited in the first user's crypto asset account has passed the decrease start period, the 1,000 coins It is determined whether or not the number of transfers is equal to or less than the set number. In the example shown in FIG. 4, since the number of transfers of 1,000 coins is 0, the updating unit 135 determines that the number of transfers of 1,000 coins is equal to or less than the set number of times, and reduces 1,000 coins. Let

Next, in the example shown in FIG. 4B, it is assumed that 100 coins out of 1,000 coins deposited in the first user's crypto-asset account are transferred to the second user's crypto-asset account. In this case, the update unit 135 determines whether or not the holding period of 100 coins deposited in the second user's crypto asset account has passed the decrease start period after the transfer, and When it is determined that the holding period after the transfer of 100 coins deposited in the asset account has passed the decrease start period, it is determined whether or not the number of transfers of 100 coins is equal to or less than the set number of times. In the example shown in FIG. 4(b), since the number of transfers of 100 coins is 1, the updating unit 135 determines that the number of transfers of 1,000 coins is not equal to or less than the set number of times, and does not decrease the number of 100 coins. end the process.

The updating unit 135 performs the same processing as in FIG. 4A for 900 coins in the first user's crypto asset account, and reduces 900 coins if it is determined that each reduction condition is satisfied. In the above description, an example in which the updating unit 135 determines whether or not the second reduction condition is satisfied after determining that the first reduction condition is satisfied has been described, but the present invention is not limited to this. For example, the updating unit 135 may determine whether or not the first reduction condition is satisfied after determining that the second reduction condition is satisfied, or may simultaneously perform the first reduction condition and the second reduction condition. You can judge.

Also, in the above description, an example in which the update unit 135 decreases the balance of crypto assets that satisfy both the first decrease condition and the second decrease condition has been described, but the present invention is not limited to this. For example, the updating unit 135 may reduce the balance of crypto assets that satisfy either the first reduction condition or the second reduction condition.

The updating unit 135 may decrease the amount according to the balance of crypto assets deposited in the user's crypto asset account. For example, the storage unit 12 stores a coefficient for decreasing the balance of the crypto-asset, and the updating unit 135 determines the amount of crypto-asset that satisfies the reduction condition among the crypto-asset deposited in the user's crypto-asset account. The amount of decrease is calculated by multiplying the balance by the coefficient stored in the storage unit 12, and the amount of decrease is subtracted from the balance of the crypto-assets to decrease the crypto-assets. The updating unit 135 subtracts the balance of the crypto assets by the initially calculated decrease amount at predetermined intervals (for example, every other week). The update unit 135 may calculate the amount of decrease at predetermined intervals, and subtract the balance of the crypto assets by the calculated amount of decrease.

The updating unit 135 may decrease the balance of crypto assets according to the type of crypto assets. Specifically, the updating unit 135 decreases the second asset out of the first asset and the second asset included in the crypto assets deposited in the user's crypto asset account.

For example, the update unit 135 multiplies the balance of the second assets that satisfy the reduction condition among the second assets deposited in the user's crypto asset account by the coefficient stored in the storage unit 12 to reduce the Decrease the crypto asset by calculating the amount and subtracting the balance of the second asset by the decrease amount. By doing so, the crypto-asset management system 1 can prevent the crypto-asset from being reduced too much.

The transfer management unit 133 may transfer the crypto-asset reduced by the update unit 135 to the crypto-asset account of the source bearer. Specifically, the transfer management unit 133 transfers the target crypto-asset to be reduced by the updating unit 135 from the user's crypto-asset account to the source bearer's crypto-asset account. By doing so, the crypto-asset management system 1 can allow the source bearer to use the unused crypto-asset.

The notification unit 136 may notify the user that the balance of the crypto-asset has been decreased when the balance of the crypto-asset has been decreased. Specifically, when the update unit 135 decreases the balance of crypto assets deposited in the user's crypto asset account, the notification unit 136 notifies the user terminal 3 used by the user that the crypto assets have decreased. Notifies a message indicating that the By doing so, the crypto-asset management system 1 can prompt the user to use the crypto-asset.

The notification unit 136 may notify the user that the balance of the crypto-asset will be decreased before the update unit 135 decreases the balance of the crypto-asset. Specifically, first, the updating unit 135 determines whether or not there is a crypto-asset that satisfies the reduction condition among the crypto-asset deposited in the crypto-asset account of each user. Then, when the update unit 135 determines that there is a crypto-asset that satisfies the reduction condition, the notification unit 136 sends the crypto-asset to the user terminal 3 used by the user whose crypto-asset account is deposited with the crypto-asset. Notify a message indicating that it will be reduced. After that, the updating unit 135 reduces the balance of the crypto assets when a predetermined period of time has passed since the notification unit 136 notified the message. By doing so, the crypto-asset management system 1 can prompt the user to use the crypto-asset.

The notification unit 136 may notify the fund bearer of the amount of decrease in the crypto-asset between the time the crypto-asset is deposited in the user's crypto-asset account and the time when the crypto-asset is transferred. By doing so, the crypto-asset management system 1 can grasp whether or not the crypto-asset provided to the user is being used.

[Sequence of information processing method]
FIG. 5 is a flowchart of an exemplary information processing method executed by the crypto-asset management system 1 according to this embodiment. In this process, the updating unit 135 determines whether there is any crypto-asset that has passed the decrease start period, which is the first decrease condition, among the crypto-assets deposited in each user's crypto-asset account. It is started when it is determined whether or not (S1).

When the updating unit 135 determines that there is no crypto-asset that has passed the decrease start period, which is the decrease condition of the holding period of the crypto-asset, among the crypto-asset deposited in the crypto-asset account of each user (NO in S1 ), the process returns to S1. On the other hand, when the update unit 135 determines that there is a crypto-asset that has passed the decrease start period, which is the decrease condition of the holding period of the crypto-asset, among the crypto-asset deposited in the crypto-asset account of each user (S1 is YES), the number of transfers of the crypto asset is specified (S2).

The updating unit 135 determines whether or not the number of transfers of the identified crypto-assets is equal to or less than the set number of transfers defined as the second reduction condition (S3). If the update unit 135 determines that the specified number of transfers of the crypto-assets is not equal to or less than the set number of times defined as the second reduction condition (NO in S3), the update unit 135 terminates the process. On the other hand, if the updating unit 135 determines that the specified number of transfers of the crypto-assets is equal to or less than the set number of times defined as the second decrease condition (YES in S3), the updating unit 135 decreases the balance of the crypto-assets (S4 ).

[Effects of this embodiment]
As described above, the information processing system S reduces the balance of crypto-assets that satisfy the reduction conditions among the crypto-assets deposited in each user's account. , Decrease the balance of crypto assets so that it is less than the amount of decrease when the number of transfers is small. By doing so, the information processing system S can provide the user with motivation to use the crypto-assets before the balance of the crypto-assets is reduced. Thereby, the information processing system S can promote the use of crypto assets. As a result, the information processing system S can activate economic circulation through the use of crypto assets.

The present invention makes it possible to contribute to Goal 9 of the Sustainable Development Goals (SDGs) led by the United Nations, "Industry and technological innovation."
