Description

The present invention relates to a digital asset clearing system for clearing contracted digital assets in transactions using digital assets, such as tokens and digital currencies, whose economic value can be digitally expressed.
In addition, the "system" in the specification of the present application is configured by combining elements such as computers and other electronic devices, software, communication networks, data, etc., and specifically performs information processing by software using hardware resources. It means the computer system that implements it.

At the world's major commodity exchanges, transactions are conducted in which the economic value of commodities, etc. is indicated in the currency issued by each country.

In recent years, digitization technology has made it easier to trade digital assets such as tokens that digitally represent the economic value of assets.
In particular, assets having a standardized economic value, such as commodities (such as products traded on commodity exchanges), have a strong characteristic of being able to be traded as digital assets.

However, conventional commodity exchanges do not have a system for processing trading orders for digital assets such as tokens.
In the past, trading of digital assets managed by decentralized technology such as blockchain has been listed on exchanges and exchanges, especially with corporate-issued tokens (defined as IEO globally and ICO domestically). There is no system that performs settlement (delivery of funds and securities) processing (such as DVP (Delivery Versus Payment: delivery of securities and payment of price at the same time) in the securities market).

The inventor of the present invention has studied and considered the construction of a system for clearing digital assets contracted in digital asset transactions on the digital asset exchange.

As a result of examination and consideration, there are various issues in the clearing process of contracted digital assets due to the presence or absence of credit of the trading participant who conducts the clearing, differences in the concept of business days among trading participants, etc. It turned out that there is

Prior to the description of the embodiments, the circumstances leading to the derivation of the present invention and the effects of the present invention will be described.

As mentioned above, in the past, trading of digital assets managed by decentralized technology such as blockchain, especially corporate-issued tokens (defined as IEOs globally and ICOs in Japan) has been listed on exchanges and exchanges. There is no system that performs settlement (delivery of funds and securities) processing (such as DVP (Delivery Versus Payment: simultaneous delivery of securities and payment of the price) in the securities market) for issues that have been issued.

The inventor of the present invention deals with all forms of digital assets, such as tokens (a general term for digitally defined values in decentralized technologies such as blockchain), digital currencies, tokens and digital currencies, or between tokens, between digital currencies, etc. It is constructed with a distributed ledger in at least one type of distributed technology such as blockchain, and a smart contract for performing predetermined processing using the digital assets managed by the distributed ledger for managing , Regarding the construction of a system for clearing digital assets contracted in digital asset transactions on the digital asset exchange, when clearing is performed using cash information via a bank account (clearing) and when using digital currency etc. Assuming the case of settlement processing (settlement) that uses digital assets that can be settled directly, we have repeatedly studied and considered.
In the process of the examination and consideration, it became clear that there were various problems described below.

1. Problems when the liquidator is a company in the clearing process of digital assets For the settlement process in this transaction, it is considered that there will be no particular problems by locking both cash and tokens with a single smart contract for settlement, or by depositing cash and tokens first.
On the other hand, in the transaction and liquidation process of a company, for example, token transactions are conducted among companies such as token issuers, crypto asset exchanges, crypto asset sales offices, and digital asset exchanges. In the case of liquidation, there are concerns about the following problems.

(1) In the case of a problem transaction on the digital asset exchange risk in individual clearing , if the net (offset) process is used for clearing, the over-buying side of tokens will deliver the excess cash, and the over-selling side of tokens will deliver the excess tokens. give.
In addition, basically, net (offset) processing is performed once a day or divided into several times.
In addition, the company without credit first delivers assets (tokens, digital currency, cash, etc.) to the liquidation counterparty.

Here, the inventors considered settlement in transactions where the issuer of an order is, for example, a token issuer, a cryptographic asset exchange, or a cryptographic asset sales outlet, and the receiver of an order is a digital asset exchange.
In this case, the rate issuer is the digital asset exchange, and the orders of the token issuer, the crypto asset exchange, and the crypto asset sales are bilateral transactions with the digital asset exchange. In effect, it is a transaction between token issuers, crypto asset exchanges, and crypto asset sales outlets.
However, at the time of clearing, there is a concept of individual clearing based on order slips, such as token issuers and digital asset exchanges, crypto asset exchanges and digital asset exchanges, and crypto asset sales offices and digital asset exchanges. occur.
It is assumed that the company with the lowest credit in these individual settlements is a digital asset exchange. In that case, the digital asset exchange will pass the assets to the clearing counterparty first.
For example, when a digital asset exchange without credit uses cash information to clear a bank account with a token issuer with credit, the digital asset exchange first uses the bank specified by the token issuer. After depositing the transaction fee into the account, the token issuer transfers the token to the digital asset exchange after confirming that the transaction fee has been deposited.
In this way, the assets to be traded will be received from the clearing counterparty after the clearing counterparty has confirmed that the digital asset exchange has delivered the assets, and the assets will not be exchanged at the same time. There is always the risk of digital asset exchanges.

Possible solutions to this problem include gross RTGS (Real Time Gross Settlement) and DVP (Delivery Versus Payment) through the net (offset). , in clearing, it is desirable to make simultaneous delivery of tokens and funds by DVP processing.

First, as the DVP processing, the inventor considered clearing using a third party service with a high credit rating, such as the DVP processing in the insurance transfer mechanism.
In that case, for example, the digital asset exchange remits the transaction fee to a digital asset exchange account in the name of a third party with high credit at a bank designated by the third party with high credit. Token issuers send tokens to third party addresses with high credit. At the timing when both this payment and the token reach the third party with high credit, the third party with high credit remits the payment to the bank account designated by the token issuer, and at the same time, to the address of the digital asset exchange. send a token.
This DVP process ensures that the digital asset exchange obtains tokens.

Next, the inventor considered performing DVP processing with a smart contract as a new type of clearing for simultaneous delivery of tokens and funds.
In that case, for example, the digital asset exchange remits the transaction amount to the digital asset exchange account in the name of the third party with high credit at the bank designated by the third party with high credit, sends the payment information (automatically processed via the bank's API) to the smart contract. Token issuers send tokens to third party smart contract addresses with high credit. When both the payment information and the token arrive at the smart contract of the third party with high credit, the smart contract of the third party with high credit remits the payment to the bank account specified by the token issuer at the same time. , send tokens to the address of the digital asset exchange.
This DVP process ensures that the digital asset exchange obtains tokens.

Next, the inventor considered performing DVP processing with a smart contract as a new type of settlement for simultaneous delivery of tokens and funds.
As a settlement, when performing DVP processing with a smart contract, it is necessary to use a suitable digital currency (generated on the same blockchain).
Then, the inventor of the present invention intends that when the digital currency and the token are deposited in the DVP processing smart contract that manages them, the DVP processing smart contract performs simultaneous delivery of the digital currency and the token. Thought.
In that case, for example, the digital asset exchange transfers the digital currency for payment to the smart contract address specified by a third party with high credit. Token issuers send tokens to third party smart contract addresses with high credit.
At the timing when both the digital currency and the token for the payment reach the smart contract of the third party with high credit, the smart contract of the third party with high credit will send the payment digital to the address specified by the token issuer. At the same time as sending the currency, send the token to the address of the digital asset exchange.
This DVP process ensures that the digital asset exchange obtains tokens.

However, as a result of repeated studies and considerations by the present inventor, it has been found that there are the following problems when a digital asset exchange manages funds entrusted by a company that is a trading participant of digital assets. bottom.

(2) Problems in entrusted management from companies There are two types of methods for digital asset exchanges to manage funds entrusted by companies that are trading participants of digital assets.

(2-1) Problems arising in entrusted management (separate management) from companies without credit , is a management method for medium-sized financial institutions and business companies with no credit.
If the digital asset trading participant is not a major crypto asset retailer, etc., but a medium-sized financial institution with no credit, first deposit cash or tokens in the management account of the digital asset exchange, make a prepayment, and It is assumed that DVP processing may not be possible directly, such as being the same processing as an individual who makes a transaction with.
The inventor of the present invention proposes to use a segregated management method so that DVP processing can be performed when a digital asset exchange manages funds entrusted by an uncredited company. Thought.

At exchanges, etc. (e.g., digital asset exchanges), segregated management consists of assets managed by the exchanges, etc. on their own and assets managed under consignment from customers, etc. without credit (e.g., medium-sized financial institutions, etc.). and manage the entrusted assets completely separately so that they cannot touch the entrusted assets.
The cash managed in the management account shall be divided into the personal portion and the entrusted portion.

(2-1-1) Problems in separate management (fear of fraudulent withdrawal of cash from trust banks)
However, if the segregated management method is used, there is a concern that a problem will arise in the process of withdrawing cash deposited at the trust bank.
When assets are deposited in a management account of a trust bank, inter-account settlement processing is sufficient to allocate from the deposited assets in individual transactions.
However, if the customer requests a withdrawal and the amount of withdrawal is large, there is a risk that this will be troublesome.

When withdrawing (withdrawing) entrusted cash from a trust bank in response to an instruction from a customer, first, the digital asset exchange uses the funds it owns to send it to the other party (the customer who instructed the withdrawal). , and then the digital asset exchange reports to the trust bank that it has been paid, allowing cash withdrawal for that report.

However, since the method of reporting that payment has been made is outdated fax or e-mail, whether or not the content of the report is actually correct depends on the creditworthiness of the company operating the digital asset exchange.
Trust banks avoid single-individual fraud factors by assigning multiple remittance managers.
However, there is concern about the possibility of multiple remittance managers colluding to commit fraud, and it is necessary to think about how to prevent such fraud.

In order to solve this problem, the inventor of the present invention proposed that when withdrawing cash entrusted by a customer entrusted to the trust bank of the digital asset exchange, , and after receiving the loan, withdraw the same amount of cash from the trust bank as the amount of the loan.
More specifically, we devised a method of temporarily procuring cash by grasping the entrusted cash managed by a trust bank and treating it like collateral (actually, it cannot be used as collateral).
As a way to achieve this, financial institutions such as money brokers with high creditworthiness (in the following explanation, we will refer to them as "high credit good.) and considered incorporating short-term funding (repo) processing.

On the premise that advance funds for withdrawal requests from customers without credit are segregated and managed by trust banks at the digital asset exchange, financial institutions with high credit will lend to the digital asset exchange. .
The digital asset exchange electronically delivers the management contents (data) of the cash entrusted by the trust bank to the financial institution with high credit. Then, the financial institution with high credit is made to finance the digital currency to the digital asset exchange within the scope of the management contents (data) of the transferred entrusted cash.
Approval of this digital currency sending transaction (transactions are generated by financial institutions with high credit such as money brokers) is not only the party (digital asset exchange) but also the digital asset exchange and the financial institution with high credit Try to do it in pairs (multisig).
The trust bank will provide the remittance data of the financial institution with high credit, which indicates that the remittance to the digital asset exchange by this loan (preferably, the financial institution with high credit will directly process the remittance) has been completed. , and the trust bank should send the amount of the remittance to the digital asset exchange to the financial institution with high credit.

(2-1-2) Issues related to cash withdrawals by others from accounts entrusted and managed by trust banks , When the trust bank can be confirmed from the processed data of the remittance transaction, to the financial institution with high credit that the trust bank has loaned to the digital asset exchange, the amount equal to the amount of digital currency remitted to the digital asset exchange However, in reality, it is not possible for anyone other than the digital asset exchange to withdraw cash from an account in the name of the digital asset exchange where the entrusted cash is managed by the trust bank. The trust bank cannot send the amount directly to the financial institution with high credit.

(2-2) Problems arising in the management method of companies with credit (DVP processing assuming deferred payment processing) Digital asset exchanges receive entrustment from companies that are trading participants in digital assets and manage assets The second method is special processing when performing DVP processing between companies with credit.
The DVP processing here is based on the premise that the company has credit and deferred payment processing (later settlement at T+1 or T+2). Clearing dates such as T+1 and T+2 are set by trading participants as part of the order data when placing a digital asset trading order, and are recorded as order data on the blockchain, so that the clearing date is set before the clearing process. It was considered as being predetermined at the time of
In order to obtain digital currency, it is necessary to deposit funds in a specific account (trust bank, etc.) and issue (exchange or convert) digital currency based on it.
However, for example, if a crypto asset sales office, a digital asset exchange, or a crypto asset exchange conducts a transaction, basically the crypto asset sales office and the digital asset exchange, or the digital asset exchange and the crypto asset exchange are liquidated. will be performed.
However, in this case, the digital asset exchange will have to perform the liquidation process twice, and the digital asset exchange will always hand over the assets to the counterparty first, so it will be difficult to process if there is no financial reserve. may become a bankruptcy factor.
In reality, the digital asset exchange only acts as an intermediary, and it is conceivable that trading participants such as crypto-asset sales offices and crypto-asset exchanges can directly settle transactions.

Therefore, the inventor of the present invention proposes a DVP process for DVP processing as a process equivalent to a process in which trading participants such as crypto-asset markets and crypto-asset exchanges directly clear each other by a clearing mechanism such as DVP processing in securities. I thought about processing with a smart contract. In the case of DVP processing, trading participants (here, between crypto-asset sales offices, crypto-asset exchanges, etc.) do not recognize clearing partners.

The smart contract for DVP processing holds transaction information of many trading participants (correctly, the smart contract for DVP processing receives the data in which the settlement information is calculated on the net (offset) from the transaction information on the digital asset exchange). digital currency and tokens to be delivered by all trading participants are deposited in the smart contract for DVP processing, and the address (account) is managed in the smart contract for DVP processing (cash and tokens for each trading participant) exchange information), if the conditions for settlement are met, in other words, the settlement process will be performed from the balance so that the cash and tokens can be exchanged immediately, and the designated addresses of both trading participants who have completed the settlement process to move digital currency or tokens to
When the liquidation counterparty's assets are insufficient, the cash and tokens deposited in the smart contract for DVP processing should not be transferred to the designated address.

In addition, regarding the above DVP processing, the present inventor calculates the net (offset) information of the trading volume of the day at the beginning of the next day after the trading of the day is completed, and at the same time, the net (offset) information of the trading volume of the day is set in the smart contract for DVP processing, and the day (T+1) when the net (offset) information of the transaction volume of the day is set in the smart contract for DVP processing, or a predetermined settlement date such as the next day (T+2), or We thought about delivering digital assets such as digital currency and tokens in the settlement method.
By this date, it is assumed that trading participants such as cryptocurrency exchanges will prepare the designated digital currency so that settlement can be processed with the smart contract for DVP processing.

The smart contract for DVP processing automatically collects the fee, and it is considered that the fee will be collected from the extent that each trading participant deposits the security deposit etc. in the smart contract for DVP processing.

(2-2-1) Problems in DVP processing assuming deferred payment processing (problems related to unification of settlement dates)
However, if the company that conducts digital asset trading is a financial institution such as a crypto asset sales office, it can be handled by T+1 processing, but non-financial institutions are also subject to digital asset trading, and companies that engage in digital asset trading are operating companies. In the case of a non-financial institution such as a financial institution, there is a problem that the settlement date cannot be unified and the settlement process becomes complicated.

(2-2-1-1) The problem of unification of settlement dates on later days Trading participants can be major retailers.
A major commercial distribution company (for example, a token issuer that is a liquidity provider) will also liquidate tokens and cash directly through DVP processing. is likely to result in delivery of the cash portion of T+2, mainly due to the convenience of the existing back office.
However, in order to collectively perform DVP processing of digital assets contracted in transactions by financial firms and non-financial firms, it is necessary to unify settlement dates. If so, the settlement date will be limited to the latest day (for example, T+2 in the above case) for financial firms and non-financial firms.

However, some cryptocurrency exchanges issue rates on the premise that they manage their own tokens, and if the period until the completion of the settlement process is long, not only does the risk increase, but it is also difficult to obtain tokens early. Desired circumstances may exist.
Therefore, from the viewpoint of managing tokens, there may be a need for real-time settlement processing as much as possible.
However, due to the liquidation circumstances of the above-mentioned major business operators, the token receipt date will be T+2.

(2-2-1-2) Problems due to differences in the concept of business days The concept of business days differs depending on the trading participant, such as the number of holidays for major business companies such as
Therefore, even if the clearing day is unified to T+2, there is a concern that it will be difficult to carry out the actual clearing process on the same day because the concept of business days differs for each trading participant.

(2-2-1-3) Problems when collateral is set for purchased tokens and tokens are loaned (Complexity of operations)
As a way to avoid these problems, a non-financial entity that has circumstances caused by having to set the settlement date to T+2 will give credit to a crypto asset sales office that needs to receive tokens early, It is possible to lend out tokens, but the procedures and processes for doing so would be extremely complicated.
For example, a non-financial business entity needs to set the purchased tokens of the crypto-asset market as collateral for the tokens lent to the crypto-asset market, which complicates operations.

In view of such problems and the like, the present inventor has further studied and considered, and as a result, has come to derive the digital asset settlement processing system of the present invention.

The digital asset clearing system of the present invention can be used in any form, such as tokens (general term for value defined digitally in decentralized technology such as blockchain), digital currency, token and digital currency, or between tokens, or between digital currencies. Distributed ledger in distributed technology such as at least one type of block chain for managing transactions between digital assets, and smart contract for performing predetermined processing using digital assets managed by the distributed ledger A system for clearing digital assets contracted in digital asset trading on a digital asset exchange, which is constructed with The smart contract for DVP processing is based on the settlement information of the digital assets of a plurality of trading participants, which is calculated on the net (offset) from the transaction information of the digital assets at the digital asset exchange. A function of acquiring and holding, a function of accepting deposits of digital assets such as digital currencies and tokens from each trading participant, and a function of accepting digital assets such as digital currencies and tokens from the respective trading participants in the smart contract for DVP processing. A function to manage with an address corresponding to a trading participant, and among digital assets such as digital currency and tokens for each trading participant managed by the address in the smart contract for DVP processing, settlement can be made with the clearing information of the digital asset Settlement processing will be preferentially performed from digital assets that can be exchanged immediately and satisfy certain conditions, and settlement will be sent to the destination address of the trading participant who is the party to the settlement process, managed in the smart contract for DVP processing. and a function to move digital assets such as digital currencies and tokens that correspond to the target.

As in the digital asset clearing system of the present invention, the DVP processing smart contract manages the digital assets such as digital currencies and tokens for each trading participant managed by the address in the DVP processing smart contract. Trading participants who are parties to the clearing process, who are the parties to the clearing process, who preferentially perform the clearing process from among digital assets that can be exchanged immediately and that meet the settlement conditions in the clearing information, and manage them within the smart contract for DVP processing. A non-financial business that has a situation due to the fact that if it is configured to have a function to move digital assets such as digital currency and tokens that are subject to settlement to the destination address, the settlement date will have to be T+2.

Then, the DVP processing smart contract 11 aggregates the unsettled portion of the tokens for which the settlement instruction has been received, and performs the settlement process with the digital assets of the trading participant 30B, etc., who is the settlement partner for the aggregated unsettled portion of the tokens. conduct.
At that time, the smart contract 14 for token generation automatically generates the shortfall of the possessed token from the temporary processing data, and passes the generated token to the smart contract 11 for DVP processing.

Clearing process without using digital currency Although the above is an example of clearing process that assumes the use of digital currency, the digital asset clearing process system of this embodiment can also perform clearing process without using digital currency. .
When digital currency is not used, a financial institution with a high credit rating (for example, a money brokerage firm. The financial institution with a high credit rating may also be a city bank) 50 sends data to a predetermined bank 60, each of the transaction participants 30A and 30B. As a consignment account from, for example, "Tanshi company/liquidator A account", "Tanshi company/liquidator B account", etc., and as a self account, for example, an account such as "Tanshi company account" is opened.
Trading participants 30A, 30B, etc., who are liquidator A, liquidator B, etc., if the contract information sent indicates cash to be delivered to the clearing partner, the financial institution (money market company) 50 with high credit Cash is transferred or deposited in advance to the respective accounts of liquidators A and B, etc. (for example, "Tanshi company/Liquidator A account", "Tanshi company/Liquidator B account", etc.) in the established bank account.
Based on the settlement information from the digital asset exchange 40, the tanshi company, trading participants 30A, 30B, etc., who are liquidators A, B, etc. in bank accounts established by a financial institution (tanshi company) 50 with high credit Check the balance of the corresponding account (“Tanshi company/Liquidator A account”, “Tanshi company/Liquidator B account”, etc.), and if there is a balance for the settlement amount, a financial institution with high credit (Tanshi company) From the corresponding accounts of trading participants 30A, 30B, etc., who are liquidators A, B, etc., in an account of a predetermined bank 60 opened by 50, the own account "Tanshi company The amount is transferred to the "Account", and "Information that locks the cash for settlement" is passed to the smart contract 11 for DVP processing.
The DVP processing smart contract 11 converts the balance of the entrusted account from each trading participant, which a financial institution (money market company) 50 with high credit has opened in a predetermined bank 60 under the name of the financial institution with high credit, into its own account. Receives information that locks the settlement amount when moving the settlement amount to , and digital tokens, etc. that are subject to settlement between the received information that locks the settlement amount and the settlement amount Assets are managed at addresses corresponding to each trading participant in the smart contract 11 for DVP processing. Among the digital assets such as tokens and the settlement amount in the information that locks the settlement amount for each trading participant 30A, 30B, etc. managed by the address in the DVP processing smart contract 11, the digital asset A token that is a party to the settlement process, which is managed in the smart contract 11 for DVP processing, by performing settlement processing from the immediately exchangeable settlement amount and digital assets such as tokens that satisfy the settlement conditions in the settlement information. Tokens and other digital assets subject to clearing are transferred to the destination address of the trading participant who is the receiver of the digital assets, etc. Send to
When the financial institution (tanshi company) 50 with high credit receives the notification of completion of settlement, it transfers the corresponding amount of its own account "Tanshi company account" established by the financial institution (tanshi company) 50 with high credit to the specified counterparty. transfer to the bank account specified by Normally, the bank account of the other party is opened at the same bank 60 as the bank 60 that opened the account of the financial institution (money broker) 50 with high credit, and in that case, transfer processing is performed.

Clearing process when the liquidator is a trading participant without credit If the liquidator is trading participant 30C with no credit As an entrusted account, for example, "digital asset exchange/liquidator C account", etc., as a self account, for example, an account such as "digital asset exchange account" is opened.
Trading participants 30C, etc., who do not have credit, if the contract information sent indicates cash to be delivered to the clearing party, each of liquidators C, etc. in the account of the trust bank 70 opened by the digital asset exchange 40 Transfer cash to an account (for example, “digital asset exchange/liquidator C account”, etc.) or deposit it in advance.
Entrusted cash management information providing means 15 receives entrustment from trading participant 30C or the like where digital asset exchange 40 does not have credit, and establishes an entrusted account other than its own at trust bank 70 (for example, "digital asset exchange The electronic data of the management information of the entrusted cash, which is managed by the clearing party C account, etc., is delivered to the financial institution 50 with high credit.
When the digital asset exchange 40 receives a withdrawal instruction for the entrusted cash from the uncredited trading participant 30C, the digital currency financing means 16 receives the entrusted amount delivered by the entrusted cash management information providing means 15. The financial institution 50 with high credit is allowed to lend the digital currency to the digital asset exchange 40 within the range of the cash of .
The digital currency repayment means 17 confirms that the remittance of the digital currency loaned to the digital asset exchange 40 from the financial institution 50 with high credit by the digital currency loan means 16 has been completed (created by the financial institution 50 with high credit) When the digital currency is remitted to the loan account management address of the digital asset exchange 40 from the trust bank 70 confirmed from the processed data of the digital currency remittance transaction, the digital currency is loaned to the digital asset exchange 40. Automatic remittance (repayment) is immediately made to the address of a financial institution 50 with high credit.
Approval of a digital currency remittance transaction that lends money to the digital asset exchange 40 from the financial institution 50 with high credit by the digital currency financing means 16 is performed by the digital asset exchange 40 and the financial institution 50 with high credit. do in

Effects of the Digital Asset Clearing System of the Present Embodiment According to the digital asset clearing system of the present embodiment, the DVP processing smart contract 11 manages trading participants 30A with addresses in the DVP processing smart contract 11. , 30B, and 30C, among digital assets such as digital currencies and tokens, liquidation processing will be preferentially performed on immediately exchangeable digital assets that satisfy the settlement conditions in the digital asset clearing information, and DVP processing will be performed. To have the function of moving digital assets such as digital currency and tokens corresponding to the clearing target to the destination address of the trading participant 30A, 30B or 30C who is the party to the clearing process managed within the smart contract 11 for clearing. Since it has been configured, Trading Participant 30A, such as a non-financial business entity, who has circumstances caused by having to set the settlement date to T+2, is a trading participant such as a digital asset sales office that needs early receipt of tokens. Even if collateral is not set for the tokens to be lent to 30B, the smart contract for DVP processing 11, when the predetermined settlement conditions are met, based on the settlement information at the timing when the predetermined settlement conditions are met , is set as part of the order data by a trading participant when placing a digital asset trading order, enabling settlement processing earlier than a predetermined settlement date at a time prior to settlement processing.
Therefore, by designating the trading participant 30A, 30B or 30C who will be the clearing partner, the clearing date or the clearing method to the DVP processing smart contract 11 at the time of depositing tokens or digital currency, etc. It becomes possible to implement settlement processing earlier than the settlement date predetermined at the previous time (early settlement processing in the case of an irregular settlement date such as a long vacation, etc.).

Further, according to the digital asset clearing processing system of the present embodiment, after the DVP processing smart contract 11 completes the transaction on the day on the digital asset exchange 40, the net (offset) information of the transaction volume on the day will be posted on the next day. A trading participant that is calculated at the beginning and has a function of acquiring the net (offset) information of the trading volume of the day in the smart contract 11 for DVP processing and managed by the address in the smart contract 11 for DVP processing. Predetermined settlement date or settlement such as the day (T+1) or the next day (T+2) on which the net (offset) information for the day's trading volume of digital assets such as digital currencies and tokens for each of 30A, 30B, and 30C is acquired method, a party to the settlement process that performs settlement processing for digital assets such as digital currencies and tokens that meet the settlement conditions in the settlement information of the digital assets and manages them within the smart contract 11 for DVP processing. Since it is configured to move digital assets such as digital currency and tokens to be cleared to the destination address of a certain trading participant 30A, 30B or 30C, clearing information can be obtained at the timing when predetermined clearing conditions are met. Based on this, it is possible to implement settlement processing earlier than the settlement date predetermined at a point in time prior to the settlement processing.

In addition, according to the digital asset clearing processing system of the present embodiment, the clearing including the issue to be traded for the digital asset, the trading participant, the trading participant who is the clearing partner of the trading participant, the clearing date or the clearing method A master information section 18 having information, and a master information section setting for setting/updating the trading participant who is the clearing partner of the trading participant, the settlement date, or the settlement method specified by the trading participant in the master information section 18 Of the digital assets such as digital currency and tokens for each of the trading participants 30A, 30B, and 30C managed by the DVP processing smart contract 11 at the address in the DVP processing smart contract 11 , (specified by the trading participant) and the transaction in the clearing information of the master information section 18 set/updated via the master information section setting/updating means 19 (specified by the trading participant) Regarding digital assets that can be immediately exchanged between trading participants who are clearing partners of the participants and meet the conditions for settlement in the digital asset clearing information, it is decided in advance at the time of the digital asset trading order. Settlement processing is performed before the settlement date, and digital assets such as digital currency and tokens that are subject to settlement are sent to the destination address of the trading participant who is the party to the settlement process, which is managed in the smart contract 11 for DVP processing. is configured to move, it is possible to perform settlement earlier than the settlement date predetermined at a time before the settlement for each of the trading participants 30A, 30B, and 30C who are the clearing counterparties.

Further, according to the digital asset clearing processing system of the present embodiment, the DVP processing smart contract 11 manages digital currencies and tokens for each of the trading participants 30A, 30B, and 30C using addresses in the DVP processing smart contract 11. , among other digital assets, each settlement date or settlement method in the settlement information of the master information section 18 set and updated for each of the trading participants 30A, 30B, and 30C via the master information section setting/updating means 19 , a trading participant 30A, 30B or 30C who is a party to the clearing process, performing clearing process for digital assets such as digital currency and tokens that meet the conditions for settlement, and managing them within the smart contract 11 for DVP processing. Since it is configured to transfer digital assets such as digital currencies and tokens corresponding to the clearing target to the destination address of Therefore, it is possible to perform the settlement process earlier than the settlement date predetermined at the time before the settlement process.

In addition, according to the digital asset clearing processing system of the present embodiment, the DVP processing smart contract 11 has a function of accepting a clearing instruction for unsettled tokens from a certain trading participant on the clearing date, and a clearing instruction It further has a function of aggregating the uncleared amount of tokens that have received a clearing instruction, and performs the clearing process with the digital assets of the trading participant who is the clearing partner for the unsettled tokens that have been aggregated after receiving the clearing instruction. Since it is configured, even if a trading participant lacks tokens for clearing on the day of clearing, if the trading participant of the clearing partner desires, the unsettled amount at that time can be aggregated and the clearing process can be performed. It is possible to perform settlement processing earlier than the settlement date predetermined at the point in time before.

Further, according to the digital asset settlement processing system of the present embodiment, the smart contract 11 for DVP processing is established by a financial institution 50 with high credit at a predetermined bank 60 under the name of the financial institution 50 with high credit. Trading participants 30A, 30B, and 30C have a function to accept information that the settlement amount is locked when the settlement amount is transferred from the entrusted account balance to the own account, and the received settlement amount A function of managing locked information and digital assets such as tokens to be settled with addresses corresponding to the trading participants 30A, 30B, and 30C in the DVP processing smart contract 11; Settlement amount and digital assets such as tokens in the information that locks the settlement amount for each trading participant 30A, 30B, and 30C managed by the address in the DVP processing smart contract 11 Settlement of digital assets Tokens, etc. that are parties to the settlement process, which are managed within the smart contract 11 for DVP processing, by performing settlement processing from digital assets such as immediately exchangeable settlement amounts and tokens that satisfy the settlement conditions in the information. Transfer the digital assets such as tokens subject to clearing to the destination address of Trading Participant 30A, 30B or 30C who is the recipient of the digital assets of Since it is configured to further have a function of sending a notification of completion to a financial institution 50 with high credit, even if digital currency is not used, settlement earlier than a predetermined settlement date before settlement processing is possible. processing becomes possible.

In addition, according to the digital asset settlement processing system of the present embodiment, the DVP processing smart contract 11 is configured to perform settlement processing for tokens and digital currency generated by the same blockchain. It becomes possible to perform settlement processing for currency using one smart contract for DVP processing.

Further, according to the digital asset settlement processing system of the present embodiment, the DVP processing smart contract 11 is the first DVP processing smart contract 11a that performs settlement processing using the digital currency generated by the first blockchain. and a second DVP processing smart contract 11b that performs settlement processing using a token generated in the second blockchain, the first DVP processing smart contract 11a and the second DVP processing smart contract 11b. The smart contract 11b receives the same settlement information, constantly communicates with each other, and exchanges the digital currency for each of the trading participants 30A, 30B, and 30C managed by the address in the first smart contract 11a for DVP processing, and the 2, each of the DVP processing smart Contracts 11a and 11b carry out the settlement process, and send to the destination address of the clearing counterparty 30A, 30B or 30C who is the party to the settlement process and managed within the smart contract 11a and 11b for DVP processing. Since the corresponding digital currency or token is configured to be transferred, even if the blockchain that is the basis of the smart contract that manages the digital currency and the blockchain that is the basis of the smart contract that manages the token is different, When predetermined settlement conditions are met, digital currency and tokens are exchanged at a time prior to the settlement process and earlier than the predetermined settlement date based on the settlement information at the timing when the predetermined settlement conditions are met. Clearing process becomes possible.

In addition, according to the digital asset clearing system of the present embodiment, the first value component that includes at least the quantity and does not include the price is set among the issue, price, and quantity that constitute the value of the token. A temporary processing data management means 12 that manages temporary processing data via a blockchain, and a second value that includes at least the price and does not include the quantity of the brand name, price, and quantity that constitute the value of the token. It further comprises a second value component setting data management means 13 for managing data in which components are set, and a token generation smart contract 14 for automatically generating a token, and the token generation smart contract 14 performs temporary processing. A value is constructed using a first value component managed via a block chain by a data management means 12 and a second value component managed by a second value component setting data management means 13. Transaction participation as a clearing partner in digital asset clearing information aggregated by DVP processing smart contract 11, which has a token generation function that generates a predetermined number of tokens with the same brand, price, and quantity that constitute the elements If the amount of tokens managed (owned) by trading participant 30A, 30B or 30C who instructed liquidation of unsettled tokens is insufficient for the amount of tokens to be delivered to party 30A, 30B or 30C, Since it is configured to automatically generate the insufficient amount of owned tokens from the temporary processing data and pass the generated tokens to the DVP processing smart contract 11, there will be a shortage of tokens for settlement on the day of settlement. Even if a Trading Participant is a Trading Participant, if the Trading Participant who is the clearing counterparty so desires, the unsettled amount at that time will be aggregated and will be processed earlier than the predetermined settlement date at a time prior to the clearing process. can embody the liquidation process of

In addition, according to the digital asset clearing processing system of the present embodiment, the digital asset exchange 40 receives entrustment from the uncredited trading participant 30C and manages it in an entrusted account different from its own in the trust bank 70. , the entrusted cash management information providing means 15 for delivering the electronic data of the entrusted cash management information to the financial institution 50 with high credit; When a withdrawal instruction is received, a digital currency loan is provided from a financial institution 50 with a high credit rating to a digital asset exchange 40 within the range of the consignment cash delivered by the consignment cash management information providing means 15. and the completion of the remittance of the digital currency loaned to the digital asset exchange 40 from the financial institution 50 with high credit by the digital currency loan means 16 (created by the financial institution 50 with high credit When the digital currency is remitted from the confirmed trust bank 70 to the loan account management address of the digital asset exchange 40 from the processed data of the digital currency remittance transaction, the digital currency is loaned to the digital asset exchange 40 Since it is configured to further have a digital currency repayment means 17 for automatically remittance (repayment) immediately to the address of a financial institution 50 with high credit, the digital asset exchange 40 is a trading participant without credit 30C The digital asset exchange 40 receives a withdrawal request from the trading participant 30C who does not have credit for cash managed by a trust bank entrusted by a financial institution with high credit, and provides a digital currency loan equivalent to the withdrawal request amount. When the money is received from the institution 50, it is possible to immediately repay the digital currency equivalent to the amount borrowed from the financial institution 50 with high credit from the cash managed by the trust bank 70 to the financial institution with high credit.

Further, according to the digital asset clearing processing system of the present embodiment, approval of a digital currency remittance transaction financed to the digital asset exchange 40 from a financial institution 50 with high credit by the digital currency financing means 16 can be digitally Since the asset exchange 40 and the financial institution 50 with high credit can perform it, the reliability of the remittance transaction of the digital currency loaned from the financial institution with high credit to the digital asset exchange 40 is improved, Unauthorized withdrawal of cash from the trust bank 70 can be prevented when the trust bank 70 confirms the processed data of the remittance transaction and transfers the digital currency to the loan account management address of the digital asset exchange 40 .

For this reason, according to the present embodiment, clearing of digital assets through trading by trading participants is possible regardless of the presence or absence of credit of the trading participant who conducts the clearing, regardless of differences in the concept of business days among trading participants, etc. A digital asset clearing system is obtained that can be processed quickly and smoothly.

Although the preferred embodiments of the present invention have been detailed above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. can be added.

For example, in the digital asset clearing system of the above embodiment, DVP processing between digital currency and tokens has been described, but the DVP process using the DVP smart contract in the digital asset clearing system of the present invention can There are no restrictions on the combination of digital assets to be cleared, such as between different digital currencies or between various tokens.

In addition, for example, if the relevant digital assets to be liquidated are not deposited in the DVP processing smart contract by the liquidation date, penalties will be collected from the collateral assets such as digital currencies that have been deposited in advance for fee withdrawals. can be

In addition, for example, in order to suppress price fluctuations, such as energy-related tokens, when the quantity is adjusted at a specific time, the DVP processing smart contract 11 will change the quantity at the time of transaction and the corrected quantity at the time of settlement. and notification of the settlement with the corrected quantity.

Further, the digital asset settlement processing system of the present embodiment shown in FIG. 1 may be integrated with the digital asset trading system 41 in the digital asset exchange 40 .
For example, order input means (not shown), digital asset transaction smart contract 41b, digital asset order management smart contract 41a, DVP processing smart contract 11, temporary processing data management means 12, second value component setting Data management means 13, token generation smart contract 14, entrusted cash management information provision means 15, digital currency loan means 16, digital currency repayment means 17, master information section 18, master information section setting/update means 19 You may

By the way, for example, in the matching processing of gold token orders, if there are four types of settlement dates or settlement methods as transaction types: T+2, T+1, T+0, and T, for example, a sell order at T+2 and a sell order at T+1 Buy orders are not subject to early liquidation, even if sell and buy orders match each other, because the delivery date is originally different.
However, the order itself meets the contract conditions. In such cases, intervening in transactions using lending (including margin trading) makes it possible to expedite the settlement process earlier than the predetermined settlement date at a time before the settlement process. is considered to be
Therefore, in the configuration in which the digital asset clearing processing system of the present embodiment is integrated with the digital asset trading system 41, the digital asset trading system 41 It is preferable to provide lending means (not shown) for lending (lending) upon request from others.
Lending is provided that the other party (liquidity provider, etc.) who wishes to borrow digital assets deposits an amount equal to or more than the interest rate from lending as margin in an account on the digital asset exchange. Lend prescribed digital assets when requested by the other party.
If there is a predetermined amount of spread (equal to or greater than the lending interest rate) between the T+2 sell order and the T+1 buy order, the liquidity provider Place an order and get it filled. At the time of the first (T+1) delivery to the other party, the lending is used for settlement.
In addition, only the range where you can have a position in lending (the amount on the lending board is the maximum value) will be contracted.
After one day, the reverse position will be liquidated, so the lending will be canceled by physical delivery after one day.
This allows a T+1 buy order to be cleared at T+1 without waiting until T+2.

The clearing processing system for digital assets of the present invention can be used for a wide range of products such as precious metals, non-ferrous metals, energies such as oil, gas, and electric power, storable agricultural products such as rice and sugar, works of art, and drinking water. and other fields that deal with transactions using digital assets whose economic value is digitally represented.

The inventor of the present invention deals with all forms of digital assets, such as tokens (a general term for digitally defined values in decentralized technologies such as blockchain), digital currencies, tokens and digital currencies, or between tokens, between digital currencies, etc. It is constructed with a distributed ledger in at least one type of distributed technology such as blockchain, and a smart contract for performing predetermined processing using the digital assets managed by the distributed ledger for managing , Regarding the construction of a system for clearing digital assets contracted in digital asset transactions on the digital asset exchange, when clearing is performed using cash information via a bank account ( clearing ), digital currency, etc. Assuming the case where settlement processing is performed (settlement) directly using digital assets that can be settled, we have repeatedly examined and considered.
In the course of the examination and consideration, the following various problems were found.

Here, the inventors considered settlement in transactions where the issuer of an order is, for example, a token issuer, a cryptographic asset exchange, or a cryptographic asset sales outlet, and the receiver of an order is a digital asset exchange.
In this case, the rate issuer is the digital asset exchange, and the orders of the token issuer, the crypto asset exchange, and the crypto asset sales are bilateral transactions with the digital asset exchange. In effect, it is a transaction between token issuers, cryptocurrency exchanges, and cryptocurrency sales outlets.
However, at the time of clearing, there is a concept of individual clearing based on order slips, such as token issuers and digital asset exchanges, crypto asset exchanges and digital asset exchanges, and crypto asset sales offices and digital asset exchanges. occur.
It is assumed that the company with the lowest credit in these individual settlements is a digital asset exchange. In that case, the digital asset exchange will pass the assets to the clearing counterparty first.
For example, when a digital asset exchange without credit uses cash information to clear a bank account with a token issuer with credit , the digital asset exchange first designates the token issuer. After depositing the transaction fee into the bank account, the token issuer transfers the token to the digital asset exchange after confirming that the transaction fee has been deposited.
In this way, the assets to be traded will be received from the clearing counterparty after the clearing counterparty has confirmed that the digital asset exchange has delivered the assets, and the assets will not be exchanged at the same time. There is always the risk of digital asset exchanges.

First, as the DVP process, the inventor considered clearing using a third party service with a high credit rating, such as the DVP process in the insurance transfer system.
In that case, for example, the digital asset exchange remits the transaction price to a digital asset exchange account in the name of a third party with high credit at a bank designated by the third party with high credit. Token issuers send tokens to third party addresses with high credit. At the timing when both this payment and the token reach the third party with high credit, the third party with high credit remits the payment to the bank account designated by the token issuer, and at the same time, to the address of the digital asset exchange. send a token.
This DVP process ensures that the digital asset exchange obtains tokens.

Next, the inventor considered performing DVP processing with a smart contract as a new type of clearing for simultaneous delivery of tokens and funds.
In that case, for example, the digital asset exchange remits the transaction amount to the digital asset exchange account in the name of the third party with high credit at the bank designated by the third party with high credit, sends the payment information (automatically processed via the bank's API) to the smart contract. Token issuers send tokens to third party smart contract addresses with high credit. When both the payment information and the token arrive at the smart contract of the third party with high credit, the smart contract of the third party with high credit remits the payment to the bank account specified by the token issuer at the same time. , send tokens to the address of the digital asset exchange.
This DVP process ensures that the digital asset exchange obtains tokens.

In order to achieve the above object, the digital asset clearing processing system according to the present invention includes tokens (general term for digitally defined value in decentralized technology such as blockchain), digital currency, tokens and digital currencies, or between tokens, At least one type of distributed ledger in distributed technology such as blockchain, and a predetermined A system for clearing digital assets contracted in digital asset transactions on a digital asset exchange, constructed with a smart contract for processing, in which transactions between contracted digital assets are mutually contracted A plurality of trading participants comprising a DVP processing smart contract for simultaneous delivery to participants, wherein the DVP processing smart contract is a net (offset) calculated from digital asset trading information at the digital asset exchange A function to acquire and hold clearing information of digital assets, a function to accept deposits of digital assets from each trading participant, and a function to correspond the received digital assets to each trading participant in the smart contract for DVP processing of the digital assets for each trading participant managed by the address in the smart contract for DVP processing, and the immediate exchange that satisfies the settlement conditions in the clearing information of the digital assets Transaction participation that is a party to the settlement process , in which the settlement process is preferentially performed among the digital assets before the settlement date predetermined at a time prior to the settlement process , and managed within the smart contract for DVP processing. and a function to move the digital asset corresponding to the liquidation target to the destination address of the person.

Further, in the digital asset clearing system of the present invention, the smart contract for DVP processing sends the net (offset) information of the trading volume of the day at the beginning of the next day after the transaction of the day on the digital asset exchange is completed. At the same time it is calculated, it has a function to acquire net (offset) information of the trading volume of the day in the smart contract for DVP processing, and is managed by the address in the smart contract for DVP processing Digital for each trading participant Settlement is possible in the settlement information of the digital asset on a predetermined settlement date or settlement method, such as the day (T+1) or the next day (T+2) on which the net (offset) information of the trading volume of the day is acquired among the assets A party to the settlement process that performs the settlement process for the digital assets that meet the conditions before the settlement date that was predetermined at the time before the settlement process, and manages it within the smart contract for DVP processing. It is preferable to move the digital asset subject to clearing to the destination address of a certain trading participant.

Further, in the digital asset clearing system of the present invention, the smart contract for DVP processing includes the digital assets for each trading participant managed by the address in the smart contract for DVP processing. Clearing process for digital assets that meet the above-mentioned conditions for settlement on each clearing date or clearing method in the clearing information of the master information unit set and updated for each trading participant via the updating means. , to the destination address of the trading participant who is the party to the settlement process, which is performed before the settlement date predetermined before the settlement process and managed in the smart contract for DVP processing, to the settlement target It is preferable to move the relevant digital assets.

Further, in the digital asset clearing processing system of the present invention, the smart contract for DVP processing has a function of accepting clearing instructions for unsettled tokens from a certain trading participant on the day of the clearing date, and a clearing instruction. and a function of aggregating the uncleared amount of tokens that have received a clearing instruction, and the clearing process with the digital assets of the trading participant who is the clearing partner for the uncleared amount of tokens that have been aggregated after receiving the clearing instruction. It is preferable to perform the settlement before the settlement date which is predetermined at a point in time prior to the processing .

Further, in the digital asset clearing processing system of the present invention, the DVP processing smart contract is established by a financial institution with high credit at a predetermined bank in the name of the financial institution with high credit. A function to receive information that locks the amount of settlement when the amount of settlement is transferred from the balance of the entrusted account to the own account, information that locks the received amount of settlement, and the settlement A function to manage the digital assets to be settled with the amount of money at the address corresponding to each trading participant in the smart contract for DVP processing, and the trading participants managed at the address in the smart contract for DVP processing the settlement amount in the information that locks the said settlement amount for each transaction, and the immediately exchangeable settlement amount that satisfies the settlement conditions in the settlement information of said digital asset among said digital assets and the digital asset before the settlement date predetermined at a time prior to the settlement process, and managed within the smart contract for DVP processing, which is a party to the settlement process. Move the digital asset subject to clearing to the destination address of the trading participant who is the recipient, and notify the financial institution with high credit of the completion of clearing for the amount of the amount subject to clearing. and a sending function.
