Description

The present invention relates to information processing devices, information processing methods and programs, and in particular to techniques for issuing and exchanging tokens on a platform.

On the existing blockchain built as an encrypted platform for using cryptocurrencies, certain individuals and companies issue tokens as new cryptocurrencies or alternative currencies without intervention. be able to.
Conventionally, there has been known a technique for exchanging one token for another on such a platform.

For example, Patent Document 1 discloses a program and a device for exchanging exchange tokens distributed at the time of ICO (Initial Coin Offering) as a means of raising funds for ordinary tokens.
Specifically, in the technology disclosed in Patent Document 1, a token for exchange is issued separately from the normal token and distributed to the ICO implementer (fund raiser), and is purchased early when the ICO is implemented. Distribute exchange tokens to investors as a privilege.

Users (ICO practitioners and investors) are conditioned to pay coins (virtual currency) equivalent to the ICO's exercise price in order to exchange the distributed exchange tokens for regular tokens.
By requiring payment of a considerable amount of coins when exchanging tokens, users are prevented from obtaining regular tokens free of charge from the exchange tokens distributed free of charge. This prevents the user from selling the acquired ordinary token at a low price less than the strike price and lowering the price of the token.

Japanese Patent No. 6500158

However, in the technique disclosed in Patent Document 1, the user cannot exchange the distributed token for a desired token unless he / she pays a coin (virtual currency) corresponding to the strike price. Therefore, the user has to prepare coins (virtual currency) in advance in order to exchange tokens, which is complicated.

On the other hand, since the ICO operator can issue a plurality of types of tokens without any particular quantitative limitation, the value of the tokens may become unstable and decline.
Thus, in the past, issuing tokens and exchanging tokens on the platform was not convenient and stable.

The token exchange unit consumes the exchange source token between the brand token unique to a third-party application service provider (ASP) participating in a transaction on the platform and the base token, and is consumed. The exchange source token may be reversibly exchanged for the exchange destination token by issuing an exchange destination token equivalent to the exchange source token.

The token exchange unit has a first brand token specific to a first third-party application service provider (ASP) participating in a transaction on the platform and a second brand specific to a second third-party ASP. The exchange source token may be reversibly exchanged for the exchange destination token by consuming the exchange source token and issuing an exchange destination token equivalent to the consumed exchange source token with the token. ..

The token exchange unit is based on the first fixed rate of the first brand token with respect to the base token and the second fixed rate of the second brand token with respect to the base token. The exchange rate for exchanging the first brand token for the second brand token may be calculated, and the first brand token may be exchanged for the second brand token based on the calculated exchange rate.

The base token may define an exchange rate for exchanging the base token for another token.

The information processing device may further include a fee issuing unit that issues the base token as an exchange fee when the token exchange unit exchanges the exchange source token with the exchange destination token.

The brand token is opened in an EC (Electronic Commerce) store or a physical store provided by a third-party ASP participating in a transaction on the platform, or an EC site provided by a company issuing company points denominated in Fiat currency. It may be available in a limited manner in the stores where it is used.

<Outline of token issuance and exchange in this embodiment>
FIG. 2 is a schematic diagram illustrating an example of each transaction of issuing a token and exchanging a token on the platform managed by the token management device 1 according to the present embodiment.
With reference to FIG. 2, the token management device 1 redeems company points 2 owned by a user with membership provided by the company for base tokens 4, for example, at a fixed exchange rate of 1: 1. Corporate point 2 is a point denominated in Fiat currency that has a value equivalent to that of Fiat currency. Corporate points 2 may be guaranteed to be exchanged with Fiat currency at a predetermined fixed exchange rate in advance. In other words, the base token 4 is a tokenized corporate point.

The token management device 1 can redeem the base token 4 to the company points 2 at a fixed exchange rate of, for example, 1: 1. The fixed exchange rate for exchanging the company points 2 and the base token 4 may be, for example, a fixed exchange rate such as 1 base token = 1 Japanese yen, but is not limited to this, and may be any fixed exchange rate. .. Further, the fixed exchange rate may be defined in the contract of the base token 4, for example. By defining a fixed exchange rate in the base token 4, unauthorized reference or falsification of the fixed exchange rate is effectively prevented.

The token management device 1 can also exchange the fiat currency 3 deposited in a bank or the like for the base token 4 at a fixed exchange rate of, for example, 1: 1 as in the case of the company points 2. , The base token 4 can be redeemed to the fiat currency 3, for example, at a fixed exchange rate of 1: 1.
By allowing redemption from the base token 4 to the deposit of corporate points 2 and fiat currency 3, the availability of the base token 4 is improved.
As described above, in the present embodiment, the base token 4 issued by the token management device 1 has a fixed value directly or indirectly in the fiat currency 3. In other words, the base token 4 is directly or indirectly backed by, i.e., available to the amount of fiat currency 3.

When the base token 4 is issued, the token management device 1 exchanges the issued base token 4 for one of the brand tokens 5a, 5b, and 5c unique to each third party ASP participating in the platform.
Specifically, in the present embodiment, the exchange between the base token 4 and the brand tokens 5a to 5c is equivalent to the consumed exchange source token on condition that the exchange source token is consumed (burn). It is executed by issuing the destination token. That is, the token exchange between the base token 4 and the brand tokens 5a to 5c is performed, for example, at an arbitrary fixed exchange rate which may be 1: 1. This fixed exchange rate may be defined, for example, in the contract of base token 4. By defining a fixed exchange rate in the base token 4, unauthorized reference or falsification of the fixed exchange rate is effectively prevented.

The fixed exchange rate between the base token 4 and each of the brand tokens 5a to 5c may be different, and each of the issued brand tokens 5a to 5c has an equivalent value with respect to the consumed base token 4. You just have to have.
Here, consuming the exchange source token means invalidating the exchange source token on the platform and setting it to an unusable state.

The token management device 1 can also exchange the brand tokens 5a to 5c for the base token 4. That is, token exchange is reversibly executed between the base token 4 and the brand tokens 5a to 5c.
In the present embodiment, since the brand tokens 5a to 5c are issued on the condition that the base token 4 is consumed, the brand tokens 5a to 5c are also indirectly fixed (pegged) value to the fiat currency 3. have. In other words, the brand tokens 5a-5c are indirectly backed by, i.e., available to the amount of fiat currency 3.

The brand tokens 5a to 5c exchanged from the base token 4 can be used as a unique virtual currency or a substitute currency within the trade area segments 6a, 6b, and 6c of the respective third party ASPs.
Users who have acquired brand tokens 5a to 5c through base token 4 using the company points 2 they own as resources will want products and services within their respective trade area segments 6a to 6c, with brand tokens 5a to 5c as consideration. Can be purchased.

The third-party ASP is an EC (Electronic Commerce) store or physical store that participates in transactions on the platform and can use any of the brand tokens 5a to 5c, or an EC provided by a company that issues company points 2. It may include stores that open on the site.
The third-party ASP transfers the brand tokens 5a to 5c unique to the third-party ASP to the token management device 1 in advance from the fiat currency 3 deposited by the third-party ASP in a bank or the like via the base token 4. It can be issued.

The third-party ASP distributes the brand tokens 5a to 5c issued in advance to new users, thereby giving an incentive to the purchase of goods and services within the trade area segments 6a to 6c. It is possible to get an opportunity to acquire a good customer.

In the present embodiment, the token management device 1 can directly exchange the brand tokens 5a to 5c with other brand tokens 5a to 5c across the trade area segments 6a to 6c without using the base token 4. ..
Specifically, as in the case of token exchange between the base token 4 and the brand tokens 5a to 5c, the exchange destination token equivalent to the consumed exchange source token is issued on condition that the exchange source token is consumed. Then, the exchange between the brand tokens 5a to 5c is reversibly executed. That is, on condition that the first brand tokens 5a to 5c are consumed, the brand tokens 5a to 5c are issued by issuing the second brand tokens 5a to 5c equivalent to the consumed first brand tokens 5a to 5c. A direct exchange between 5c is performed.

The token management device 1 may collect a predetermined token exchange fee from a user who intends to exchange brand tokens 5a to 5c with each other.
Specifically, for example, the token management device 1 consumes the exchange source brand tokens 5a to 5c by reducing the amount of the exchange source brand tokens 5a to 5c by a predetermined exchange fee and reducing the amount by the exchange fee. Then, the exchange destination brand tokens 5a to 5c are issued and sent to the user. Further, the token management device 1 may consume the exchange source brand tokens 5a to 5c for the exchange fee to issue the base token 4 and acquire the base token 4 as the exchange fee. By collecting exchange fees, it is possible to strengthen the operational base for issuing and exchanging tokens on the platform.

In FIG. 2, the user who owns the company point 2 may be authenticated by a customer confirmation operation such as KYC (Know Your Customer) when trying to participate in the platform of the encrypted token of FIG.
Similarly, the third-party ASPs constituting the trade area segments 6a to 6c on the platform of FIG. 2 may also be authenticated by a customer confirmation operation such as KYC.

Thus, in this embodiment, in order to exchange the deposit of corporate points 2 and fiat currency 3 for tokens that can be used on the platform, the user or the third party ASP who owns the deposit of these corporate points 2 or fiat currency 3 On the other hand, it becomes easy to encourage participation in transactions on the platform.
Further, in the present embodiment, the values of the base token 4 and the brand tokens 5a to 5c issued by the token management device 1 are supported by being fixed to the amount of the company point 2 or the fiat currency 3 from which these tokens are exchanged. Has been done.
Further, in the present embodiment, since the exchange source token is consumed when the exchange destination token is issued, the total value (total amount) of the tokens existing on the platform is always maintained constant.
That is, in the platform of FIG. 2, since the total value (total amount) of the base token 4 and the brand tokens 5a to 5c is always supported by the company point 2 denominated in the fiat currency 3 or the fiat currency 3, the token management device. The total amount of tokens issued by 1 will be controlled within the total value of corporate points 2 and fiat currency 3 denominated in fiat currency 3.

FIG. 3 is a diagram illustrating an example of a blockchain network configuration in which the platform of FIG. 2 is implemented.
With reference to FIG. 3, in the blockchain 31, the server 32a and the server 32e are connected to each other via the network, and the terminal 32b, the terminal 32c, the terminal 32d, the terminal 32f, the terminal 32g, and the terminal 32h are connected to each other.
The terminal 32b, the terminal 32c, the terminal 32d, the terminal 32f, the terminal 32g, and the terminal 32h may be a personal computer (PC), and may be any information processing device such as a portable information terminal such as a tablet terminal or a smartphone. There may be.

The blockchain 31 generates data including data of several transactions and hash values as one block, and the generated blocks are connected in a chain shape and then shared among a plurality of nodes. Non-tamperable information. It is a shared platform.
The blockchain 31 in FIG. 3 may be a consortium type having a plurality of management entities, but is not limited to this, and is, for example, a private type having a single management entity or a public type having no central administrator. You may.

Both the base token 4 and the brand tokens 5a to 5c of the present embodiment are anchored on the blockchain 31. That is, the transaction history of issuance, redemption, exchange, etc. of the base token 4 and the brand tokens 5a to 5c is hashed and written in the block, and is recorded as a locus on the blockchain 31. This makes it impossible to tamper with the transaction data, and a secure and robust token transaction is realized.
The configuration of the blockchain 31 shown in FIG. 3 is an example, and the blockchain 31 does not have to include the server 32a and the server 32e, and may be configured by any number of information processing devices. Further, instead of the blockchain 31, the network may be configured by a server / client type or a parallel processing type.

<Functional configuration of token management device>
FIG. 4 is a block diagram showing an example of the functional configuration of the token management device 1 according to the present embodiment.
The token management device 1 shown in FIG. 2 includes an input unit 101, a token issuing unit 102, a redemption unit 103, a token exchange unit 104, and a fee management unit 105.

The input unit 101 inputs various instructions to the token management device 1 via the user's terminal device or the like. Various instructions input to the input unit 101 are an instruction to exchange the company point 2 or the fiat currency 3 for the base token 4, an instruction to redeem the base token 4 to the company point 2 or the fiat currency 3, the base token 4 and the brand token 5a. Includes instructions for exchanging tokens with ~ 5c and instructions for exchanging tokens between brand tokens 5a ~ 5c. These instructions may include token issuance amount (issue amount), token exchange amount (exchange amount), exchange source and exchange destination token types.

The input unit 101 also accepts input of various parameters necessary for executing issuance and exchange of tokens.
The various parameters required to execute token issuance and exchange are the fixed exchange rate between company point 2 and base token 4, the fixed exchange rate between base token 4 and brand tokens 5a to 5c, respectively. Includes exchange fees between brand tokens 5a to 5c. These various parameters may be input by the administrator of the token management device 1.
The input unit 101 stores various data such as various input instructions and various parameters in advance in a non-volatile storage device such as the HDD 14, and the token issuing unit 102, the redemption unit 103, the token exchange unit 104, and the fee management unit 105 store them in advance. Various input data stored in the storage device may be read out and used for processing by each component.

The token issuing unit 102 issues the base token 4 based on the instruction input to the input unit 101 for exchanging the company points 2 for the base token 4. The company point 2 is denominated in Fiat currency 3 and is guaranteed to be exchanged with Fiat currency 3 at a fixed exchange rate in advance.

In the base token 4, for example, a fixed exchange rate of 1: 1 is defined in advance as an exchange rate between the fiat currency 3 and the base token 4. Therefore, by designating the number of points of the company points 2 that the user wishes to exchange for the base token 4, the token issuing unit 102 has an amount (amount) equivalent to the amount of the company points 2 denominated in fiat currency 3. ) Base token 4 can be issued.
The user may input the amount of the base token 4 to be issued into the input unit 101 instead of the number of points of the company points 2.

The token issuing unit 102 may issue the base token 4 in exchange for the electronic money owned by the user, the fiat currency 3, the virtual currency, or the like, instead of the company points 2.
In this case, it is assumed that the electronic money and the virtual currency are denominated in Fiat currency 3 as in the case of corporate points 2, and exchange with Fiat currency 3 at a fixed exchange rate is guaranteed in advance.
The token issuing unit 102 also issues the base token 4 in exchange for the fiat currency 3 owned by the third party ASP based on the transaction request from the third party ASP that constitutes and operates each trade area segment 6a to 6c. You can do it.

The redemption unit 103 redeems the base token 4 to the company point 2 based on the instruction input to the input unit 101 to redeem the base token 4 to the company point 2.
The company points 2 are redeemed from the base token 4 at an exchange rate between the fiat currency 3 defined in the base token 4 and the base token 4, for example, a fixed exchange rate of 1: 1.
Therefore, when the user specifies the number of points of the company points 2 that the user wishes to redeem from the base token 4, the redemption unit 103 uses the base token 4 in an amount (amount) corresponding to the amount denominated in Fiat currency. It can be redeemed to company points 2.
The user may input the amount of the base token 4 to be redeemed into the input unit 101 instead of the number of points of the company points 2.

The token exchange unit 104 reverses the token between the base token 4 and the brand tokens 5a to 5c based on the token exchange instruction between the base token 4 and the brand tokens 5a to 5c input to the input unit 101. Exchange.
The token exchange unit 104 is also a token between one brand token 5a to 5c and another brand token 5a to 5c based on the token exchange instruction between the brand tokens 5a to 5c input to the input unit 101. Is reversibly exchanged.

In the present embodiment, the token exchange unit 104 realizes token exchange by issuing an exchange destination token equivalent to the consumed exchange source token on condition that the exchange source token is consumed. .. Here, equivalence means that the exchange source token and the exchange destination token are of equal value using a predefined fixed exchange rate.
Therefore, the total value (total amount) of the tokens existing on the platform, that is, the base token 4 and the brand tokens 5a to 5c, is always maintained constant. The value of these base tokens 4 and brand tokens 5a to 5c is fixed and supported by the amount denominated in Fiat currency 3, and the value is guaranteed.
The user only needs to input the amount of the exchange source token to be exchanged and the token type between the exchange source token and the exchange destination token in the token exchange instruction, and does not need to specify other exchange conditions.

Further, in the present embodiment, the token exchange unit 104 can directly exchange brand tokens 5a to 5c with each other without going through the base token 4.
Temporarily, in order to exchange brand tokens 5a to 5c with each other, the brand tokens 5a to 5c of the exchange source are consumed to issue the base token 4 once, and then the issued base token 4 is consumed to consume the brand tokens 5a to the exchange destination. When 5c is issued, two transactions are generated to exchange the brand tokens 5a to 5c with each other.

On the other hand, in the present embodiment, since the brand tokens 5a to 5c are directly exchanged with each other, one transaction is sufficient for exchanging the brand tokens 5a to 5c with each other, and the operation load of the user and the processing of the token management device 1 are required. The load is reduced. However, the exchange between the brand tokens 5a to 5c is not limited to the direct exchange, and the indirect exchange between the brand tokens 5a to 5c may be performed via the base token 4.
Further, a third-party ASP (store) that organizes trade area segments 6a to 6c in which the exchange source and exchange destination brand tokens 5a to 5c can be used has previously used the brand tokens 5a to 5c for exchange with the base token 4. It is not necessary to make a deposit in the token exchange unit 104. Therefore, the workload of the third party ASP is also reduced.

The fee management unit 105 collects and manages fees incurred when issuing and exchanging tokens.
The fee management unit 105 may collect an exchange fee when exchanging brand tokens 5a to 5c with each other, for example. Specifically, the fee management unit 105 reduces the amount of the exchange source brand tokens 5a to 5c by the predetermined exchange fee, and consumes the exchange source brand tokens 5a to 5c for the exchange fee to consume the base token 4 May be issued and the issued base token 4 may be collected as an exchange fee.

The fee management unit 105 may also collect a system usage fee from a third party ASP (store) participating in the platform.
Specifically, the fee management unit 105 is in place when a third party ASP newly joins the platform, regularly, or when a user or a third party ASP issues brand tokens 5a to 5c. Base token 4 may be collected from a third-party ASP as a system usage fee with a fixed amount or a pay-as-you-go system. The fee management unit 105 may collect the base token 4 previously owned by the third party ASP as a system usage fee, or the base token based on the brand tokens 5a to 5c owned by the third party ASP or the fiat currency 3. 4 may be issued and the issued base token 4 may be collected as a system usage fee.
Alternatively, when the fee management unit 105 issues the brand tokens 5a to 5c for a third-party ASP, the fee management unit 105 uses the base token 4 of the issuance fee of the brand tokens 5a to 5c to the third-party ASP. You may request payment.

It should be noted that at least a part of the functions of each element of the token management device 1 shown in FIG. 4 can be realized by executing the program by the CPU 11 of FIG. However, at least a part of the functions of each element of the token management device 1 shown in FIG. 4 is made to operate as dedicated hardware such as an integrated circuit (Integrated Circuit: IC) and an LSI (Large Scale Integration: LSI). You may. In this case, the dedicated hardware operates based on the control of the CPU 11.

<Processing procedure for base token issuance processing>
FIG. 5 is a flowchart showing an example of a processing procedure of the base token issuance process executed by the token management device 1 according to the present embodiment.
Each step in FIG. 5 is realized by the CPU 11 reading and executing the program stored in the storage device such as the HDD 14 of the token management device 1. Further, at least a part of the flowchart shown in FIG. 5 may be realized by hardware. When it is realized by hardware, for example, by using a predetermined compiler, a dedicated circuit may be automatically generated on FPGA (Field Programmable Gate Array) from a program for realizing each step. Further, a Gate Array circuit may be formed in the same manner as the FPGA and realized as hardware. Further, it may be realized by ASIC (Application Specific Integrated Circuit). The same applies to the processes of FIGS. 6 and 7 described later.

In S51, the input unit 101 of the token management device 1 receives the input of the issuance instruction of the base token 4 from the user's terminal device or the like via the communication I / F17.
