Description

Method of applying the trading rules of blockchain-based cryptocurrency, terminal device and program for performing the same

The present invention relates to a method of applying a transaction rule of a blockchain-based cryptocurrency, and relates to a terminal device and a program for processing a transaction according to a transaction rule defined in a blockchain-based smart contract (SMART CONTRACT).

Recently, interest in bitcoin, which is a kind of digital cryptocurrency that can pay for spots, has been highlighted.

Bitcoin is a digital currency created by Satoshi Nakamoto in 2009 and has a structure in which a central device for issuing and managing currency does not exist. Instead, Bitcoin transactions are made by a distributed database based on a peer-to-peer network (P2P), and usually perform transactions using a public key encryption algorithm.

In addition to Bitcoin, digital coins that can be paid for in kind are Litecoin, Darkcoin, Namecoin, Doggycoin, Ripple, etc.The common characteristics of these are traders using digital cryptocurrency including Bitcoin. The book of the transaction details thus traded is stored in the electronic wallet, and the book is sequentially connected according to block and hash conversion in a certain unit, and can be shared on the blockchain network in a form that can be verified by hash comparison. Bitcoin, Litecoin, Darkcoin, Namecoin, Doggycoin, Ripple, etc. can be exemplified as such cryptocurrency.

The individual blocks connected to the blockchain may be sequentially connected according to hash transformation, and may be configured in the form of a data packet including a plurality of information. For example, information included in a block may be a transaction history in which participants exchange currency, and a hash value, difficulty, and nonce of the previous block. Every block contains the hash value of the previous block, and the blocks following this can form a blockchain that contains the transfer details that occurred in chronological order.

When such a blockchain network is formed, one transaction book can be shared through nodes connected to the network, and the transaction book can be preserved by a blockchain that is verified and formed by an unspecified number of nodes. Since such a transaction ledger is continuously shared and verified and shared by all node terminals connected to the network, forgery and alteration of the transaction ledger is prevented by a majority of nodes that want to maintain the transaction system.

In addition, the target of an attack such as hacking into the blockchain network should be the transaction system itself composed of a plurality of unspecified nodes rather than a specific terminal, and the action itself destroys the transaction system itself, in preparation for hacking costs. It is possible to prevent the establishment of hacking itself in advance due to the low value of the gain, so it is possible to establish a reliable distributed transaction of cryptocurrency without any central control.

However, the cryptocurrency formed on the basis of such a blockchain is very difficult to lead to active use in the real economy due to the instability of its value and the inconvenience of real use due to the delay in approval time caused by the limitations of the blockchain network system. .

In addition, due to its instability and anonymity, there are cases where legal restrictions on use are made at the national level.

In particular, in order to solve the underlying cause of value instability, a cryptocurrency formed by a blockchain network is secured in a specific fiat currency or other cryptocurrency, and as a result, a stable coin in which the value becomes the same as the fiat currency ( STABLE COIN) method is also proposed.

However, the proposed collateral stabilization methods so far require another currency to be collateral, which results in the same volatility as the value volatility of the other currency. The problem has not been solved.

In addition, excessive stabilization lowers the profitability for holdings or the need for currency trading, and the number of holders decreases, thereby decreasing usability.

In other words, the fundamental problems of stabilizing the value of cryptocurrency itself, creating value through transactions, and improving usability in real economic life are still being raised.

The terminals described herein may include mobile phones, smart phones, laptop computers, digital broadcasting terminals, PDAs (Personal Digital Assistants), PMPs (Portable Multimedia Players), navigation, server devices, and the like. However, the present invention is not limited to this, and may be various devices capable of user input and information display.

To this end, each trader terminal may be provided with a communication module for accessing the blockchain network. The blockchain network may be implemented as a wired network such as a local area network (LAN), a wide area network (WAN), or a value added network (VAN). In addition, the blockchain network is a mobile radio communication network (mobile radio communication network), satellite communication network, Bluetooth (Bluetooth), Wibro (Wireless Broadband Internet), HSDPA (High Speed Downlink Packet Access), Wi-Fi (Wi-Fi), LTE (Long Term) Evolution) and the like. If necessary, the blockchain network may be a mixed wired and wireless network.

And each trader terminal can register the account information according to their node access to the transaction book data shared in the cloud manner through the network. And, when a transaction of cryptocurrency is required, each trader terminal can propagate the transaction information to be recorded in the transaction book data to each trader terminal.

In addition, each trader terminal can use a smart contract (SMART CONTRACT) pre-shared on the blockchain network by processing such that a specific transaction system process cannot be forged / modulated based on the transaction book data provided as described above. . Such a smart contract may include a blockchain-based transaction system process such that post-forgery / falsification is not possible, and cryptocurrency-specific attributes, issuance conditions, transaction conditions, incineration conditions, and authority setting information for each trader.

And, when a process based on a smart contract is processed, or according to an approval process corresponding to a cryptocurrency transaction, for example, when an approval is processed from a node terminal having a certain percentage or more, the transaction book data is updated and the information is shared. , Transaction of cryptocurrency and execution of smart contract can be processed.

Here, the transaction ledger data is a block chain having a structure in which a plurality of blocks are sequentially connected according to a generation order by allowing the current block to contain a hash value for a previously generated block for each block corresponding to a certain time or unit ( block chain) data.

Accordingly, verification of forgery of the transaction book data can be easily processed according to verification of the hash value of the blockchain. To this end, each trader terminal may provide computing power to perform arithmetic and verification processing to calculate a hash value of the next block, and may obtain compensation corresponding thereto.

The security stability of this blockchain can be formed by the system participation of sharers who share data. Accordingly, a block of transaction information including a history of sharing and issue / transaction history of sharing between each sharer terminal connected to the blockchain network can be sequentially stored, and hash values for preventing forgery are sequentially blockchained Transaction verification (work proof) processing to be performed may be distributed in each trader terminal.

Accordingly, referring to FIG. 2, each processing unit and modules of the system according to an embodiment of the present invention may be implemented as a DECENTRALIZED APPLICATION based on a smart contract, using the blockchain network configured as such as the main net. Can be.

In particular, in the exchange service providing apparatus 100 constituting this, the issuance, transaction, conversion and management of the second cryptocurrency based on the main net-based first cryptocurrency and the real value, and other cryptocurrencies previously issued on the main net basis An inter-trade service and a cross-currency transaction service can be provided, and further, a real value exchange and incineration process of real-value-linked second cryptocurrency is provided, which will be described later in more detail.

Referring to FIG. 2, the exchange system according to an embodiment of the present invention includes an exchange service providing apparatus 100 and a trader terminal 300 based on a blockchain network, and the exchange service providing apparatus 100 is prepared for payment It is connected to the adjustment module 400, the financial server 500, and the real value providing device 200 to provide an exchange processing and transaction service according to an embodiment of the present invention.

More specifically, the exchange service providing apparatus 100 may issue the first cryptocurrency that is issued and distributed based on the distributed transaction, and the issued first cryptocurrency data may be distributed to the trader terminal 300. The trader terminal 300 purchases / sells the first cryptocurrency in another legal or cryptocurrency, or through the exchange service providing device 100, the second according to the ratio of real economic value conversion corresponding to the first cryptocurrency You can request to convert cryptocurrency.

Then, the exchange service providing apparatus 100 may issue the second cryptocurrency according to the request to switch to the second cryptocurrency and pay it to the trader terminal 300. Here, the second cryptocurrency may be processed to be issued in a condition that can be incinerated by a value payment process corresponding to the real economic value, according to a process for preparing the actual economic value.

The actual economic value represents the value of actual goods and services, and the trader terminal 300 can transmit a value payment request corresponding to the second cryptocurrency to the exchange service providing apparatus 100, and exchanges when a value payment request is received The service providing device 100 transmits the request data corresponding to the value payment to the real value providing device 200, so that the real value providing device 200 is a user of the trader terminal 300 with the actual goods or services according to the quantity. The payment process can be controlled so that it can be paid to.

Accordingly, the first cryptocurrency can be traded between other cryptocurrencies and statutory currencies, so the value volatility may be relatively high, but it is possible to provide real goods and services according to the conversion to the second cryptocurrency. The value volatility becomes stable and controllable by adding the linkage by value provision.

In addition, the second cryptocurrency may be determined in quantity and issuance according to the value of the actual goods or services, and the exchange service providing apparatus 100 may process the payment preparation process for issuance in advance, and the user At any point in time, the second cryptocurrency can be converted into goods or services as real economic values. Accordingly, the converted second cryptocurrency can be incinerated.

Here, various types of goods or services provided by the real value providing apparatus 200 may be exemplified, and in the embodiment of the present invention, gold whose value is recognized as globally and historically stably may be exemplified.

Accordingly, the real value providing device 200 may be a gold trading device, such as a gold exchange server or a gold storage server.

Then, the exchange service providing apparatus 100 may perform conversion processing to the second cryptocurrency corresponding to the first cryptocurrency exchange rate according to the gold price information. In addition, the exchange service providing device 100 delivers a gold purchase request in a quantity corresponding to the second cryptocurrency to the real value providing device 200, or requests delivery of gold according to a gold exchange gift certificate already purchased according to a payment preparation process May be delivered to the real value providing device 200, or a delivery request for the physical gold already purchased and stored according to the payment preparation process may be delivered to the real value providing device 200.

Accordingly, since the trader terminal 300 holds the second cryptocurrency based on the distributed transaction book that can be exchanged for gold at any time, even if the gold is not directly held, more efficient asset management may be possible.

However, the object of real value can be modified in various ways. In addition to gold, the second cryptocurrency is precious metals (silver copper diamonds), asset goods (gift certificates, luxury goods, antiques, etc.), and asset services (plastic surgery) Volume, massage, education, etc.), and accordingly, the real value providing apparatus 200 may perform individual provisioning processing according to the form and attribute of each real value.

On the other hand, in the payment preparation rate adjustment module 400, the conversion of the first cryptocurrency to the second cryptocurrency issued and distributed by the exchange service providing apparatus 100, and the process of converting the actual value of the second cryptocurrency accordingly It is possible to set the payment reserve ratio to be maintained, and accordingly, as the payment reserve ratio is maintained, it is possible to perform analysis and adjustment processing of cryptocurrency distribution volume and payment reserve to maintain the stability of the trading platform and the system.

The payment preparation rate adjustment module 400 may determine whether or not payment preparation is necessary based on the predictive model, or may conditionally determine a policy process corresponding to the payment preparation need, and the financial server 500 according to the appropriate policy decision and execution by situation The financing process of the furnace can be further performed.

According to this system, the first cryptocurrency can be issued and distributed stably, it can be converted into the second cryptocurrency linked to the real value quote, and the second cryptocurrency can be converted and paid to the real value when necessary. It is possible to block the cryptocurrency issuance, management, and trading platform that can bring together the value stabilization of the cryptocurrency itself by real economic value, the creation of value by transaction, and the usability improvement in real economic life. It can be provided through network-based distributed processing.

3 is a block diagram showing a configuration of a service providing apparatus according to an embodiment of the present invention, and FIG. 4 is a block diagram showing a configuration of a service processing unit included in a service providing apparatus.

Referring to Figure 3, the exchange service providing apparatus 100 according to an embodiment of the present invention, the exchange service processing unit 110, the control unit 130, the communication unit 120, the user input unit 140, the memory 150 It can contain.

Referring to FIG. 4, the service processing unit 110 includes a first cryptocurrency management unit 111, a second cryptocurrency management unit 112, a currency conversion processing unit 113, a payment preparation unit 114, and a real value exchange processing unit 115 ), An incineration processing unit 116, a legal currency transaction service unit 117, and a cryptocurrency transaction service unit 118.

The communication unit 120 may include one or more modules that enable communication between the terminal 100 and the blockchain network. For example, the communication unit 120 may include a mobile communication module, a wireless Internet module, a short-range communication module, or a wired communication module.

The user input unit 140 may include one or more interface modules for receiving user input.

Here, the user input unit 140 may receive interface input information for service provision and management of the exchange service providing apparatus 100 and perform exchange service processing.

The control unit 130 controls the overall operation of the apparatus 100 for providing an exchange service, and may provide storage and processing of distributed transaction information received from a blockchain network.

In addition, the control unit 130 may provide the processing of the requested transaction information to the blockchain network, and further, through the exchange service processing unit 110, the above-mentioned cryptocurrency issuance, transaction, currency conversion, real value exchange, Processing such as incineration can be processed based on a blockchain network.

In particular, the control unit 130 may share the cryptocurrency transaction information according to the above-described exchange service processing on the blockchain network, and according to the approval result corresponding thereto, the cryptocurrency transaction information may be updated in the transaction book data.

The process for the cryptocurrency processing of the exchange service processing unit 110 may be pre-registered in the form of a code such as a smart contract in the transaction book data shared on the blockchain network, and thus forgery and alteration can be prevented. Can be.

More specifically, the first cryptocurrency management unit 111 performs the management of the amount of storage according to the issuance and transaction service of the first cryptocurrency.

In issuing the first cryptocurrency, the first cryptocurrency management unit 111 may manage the initial issuance amount by dividing it into an internal holding amount and an external circulation amount.

In the case of the internal holding amount, it is the amount required for the payment preparation ratio control management of the payment preparation unit 114, for example, it can be delivered and managed to a central bank account having a separate storage authority. And, in the case of external distribution, as the amount of distribution distributed to the trader terminal 300, it may be subject to the sale or purchase process by the legal currency transaction service unit 117 and the cryptocurrency transaction service unit 118. The trader may usually be able to process the purchase / sale of external distribution.

Here, the legal currency transaction service unit 117 and the cryptocurrency transaction service unit 118 are capable of processing the transaction service of the first cryptocurrency corresponding to the legal currency or other cryptocurrency, respectively, and each transaction service unit 117 , 118) may allow the market price to determine the transaction price between the first cryptocurrency and the first cryptocurrency and other cryptocurrency, respectively, and purchase / sell or other cryptocurrency corresponding to the first cryptocurrency. It can provide currency exchange service.

Here, the first cryptocurrency can be formed by the autonomous transaction between each seller and buyer in the exchange. The transaction service units 117 and 118 directly exchange transaction services that exchange the first cryptocurrency held in the user's account for fiat currency or other cryptocurrency, or exchange the fiat currency or other cryptocurrency held for the first cryptocurrency. It can provide a transaction brokerage service that brokers transactions through other exchanges.

Accordingly, the first cryptocurrency has a market value determined by an autonomous transaction by a trading service, and may have inherent volatility. In addition, the first cryptocurrency may be convertible to the second cryptocurrency as much as possible.

In addition, since the second cryptocurrency according to an embodiment of the present invention can be exchanged for real economic real value, the value of the second cryptocurrency may be the same as the real economic value, and the volatility of the real value may be very low. .

For example, the second cryptocurrency may be gold, and the payment ratio of 1 g of gold per unit quantity of the second cryptocurrency may be 1: 1. On the other hand, the transaction price of the first cryptocurrency can be changed in real time, and the exchange rate and the switchable quantity to the second cryptocurrency can be varied.

For example, if it was possible to convert one second cryptocurrency into the first cryptocurrency unit quantity according to the transaction price yesterday, according to the transaction price of the first cryptocurrency rising, today the two second cryptocurrency units are in one unit quantity. It can be converted into cryptocurrency.

On the other hand, since the second cryptocurrency maintains the same value according to the gold price, its volatility depends only on the change in the gold value, so it can have a stable form.

Therefore, even if the market value volatility of the first cryptocurrency exists, the actual value change can be controlled by the stable volatility of the second cryptocurrency, so that rapid inflation or deflation is prevented and the value volatility is adjusted. And stable maintenance of the transaction system.

To this end, according to an embodiment of the present invention, the first cryptocurrency may be converted into the second cryptocurrency according to a predetermined conversion amount and a conversion ratio. In addition, the conversion ratio may be determined according to market price information of real value goods or services exchangeable in correspondence with the transaction price of the first cryptocurrency and the second cryptocurrency.

For example, when the real value that can be exchanged in the quantity of one unit of the second cryptocurrency is 1 g of gold, the first cryptocurrency can be converted into the second cryptocurrency by a predetermined amount. The predetermined quantity may be determined according to the weight of gold that can be exchanged for the second cryptocurrency, and the quantity that can be converted to the second cryptocurrency among the first cryptocurrency may be different depending on the authority and level of the user requesting the conversion.

And the exchange rate from the first cryptocurrency to the second cryptocurrency can be calculated by the price of the first cryptocurrency, the exchangeable gold weight, and the gold price, and the conversion amount of the second cryptocurrency according to the exchange is [the first cryptocurrency]. The second cryptocurrency conversion quantity per unit = (the exchangeable gold weight) x (the highest market price per gold weight) / (the lowest transaction price of the first cryptocurrency per transaction unit)].

Then, the second cryptocurrency management unit 112 performs processing for issuing and holding the second cryptocurrency.

In particular, the second cryptocurrency management unit 112 may calculate the amount of issuance according to the payment preparation information of the payment preparation unit 114. For example, the payment preparation information is payment reserve information, and may include information on the amount of gold that can be paid or cash information on which gold can be purchased, and the second cryptocurrency management unit 112 sets a certain amount of reserve based on the payment reserve. While maintaining, it is possible to calculate the amount of issuance as much as possible. For example, the amount of issuance may be adjusted such that the reserve for payment is maintained at a certain ratio to the market capitalization of the first cryptocurrency in circulation. Then, the second cryptocurrency management unit 112 may issue the second cryptocurrency that can be issued as a condition that can be incinerated by value payment or exchange processing corresponding to the real economic value.

In addition, the second cryptocurrency may be issued according to a request to convert the currency corresponding to the first cryptocurrency of the trader terminal 300.

To this end, the currency conversion processing unit 113 calculates a switchable amount according to the payment preparation information in advance, and determines the second switchable cryptocurrency amount among the first cryptocurrency, so that the second cryptocurrency management unit 112 and the trader terminal 300 ).

Accordingly, the second cryptocurrency management unit 112 may issue the second cryptocurrency in the amount determined by the currency conversion processing unit 113, and the issued second cryptocurrency may have the same payment value as the real value object. There will be.

On the other hand, as the real value exchange processing unit 115 receives the request for payment or exchange of the second cryptocurrency from the trader terminal 300, the value providing device 200 for requesting a real value corresponding to the quantity corresponding thereto ).

For example, the real value exchange processing unit 115 provides a value providing device 200 with delivery request information that allows gold or gold bars corresponding to the second cryptocurrency to be delivered to a registered destination for the trader terminal 300. Can be delivered to. In addition, the real value exchange processing unit 115 may receive qualification information or personal identification information corresponding to the trader to be delivered from the trader terminal 300 in advance, and may be used for real value payment or exchange proof, but the present invention is limited to this. It is not.

On the other hand, the second cryptocurrency in which the exchange processing in the real value exchange processing unit 115 is completed may be incinerated in the blockchain network by the incineration processing unit 116.

On the other hand, the first cryptocurrency management unit 111 may perform conversion management processing to an internal reserve amount for the first cryptocurrency converted to the second cryptocurrency. The internal holding amount is not the quantity that is circulated externally, but is used to adjust the calculation of the payment preparation rate in the payment preparation unit 114, so that the overall system and inflation stability can be promoted.

In the present invention, a smart contract is a code that is compiled into executable byte code and can be executed on at least one computing device, and is configured to perform a predetermined procedure when certain conditions are satisfied at the time of execution. The integrity of the execution result value as a result of refers to the concept characterized by being verified by consensus on the execution result value calculated from the at least one computing device.

Smart contract refers to program code that can execute and execute contracts or negotiations using blockchain technology. Thus, the entire process can be automated by program code to supplement or replace legal contracts.

The cryptocurrency storage function of the existing blockchain 1.0 can be programmed in various forms. Among multiple cryptocurrencies, ethereum is a blockchain system that can execute smart contracts and can provide a global platform through EVM (Ethereum Virtual Machine). Developers can execute smart contracts through programming and manage digital assets such as cryptocurrencies.

Here, Ethereum was developed to use a platform to record various information such as SNS, e-mail, and electronic voting to overcome the difficulty of consultation due to the vastness of the Bitcoin network.

Ethereum can provide account management, call generation and mining, and can use smart contracts and distributed applications (Dapps) to run applications on EVM.

Nick Szabo, the first creator of smart contracts, defined smart contracts as a highly developed and automated way to implement contracts between machines in an unreliable computer networking environment, and distributed various applications such as real estate contracts, online voting and healthcare on the blockchain. The platform was extended to allow development.

Currently, the most important technology in Blockchain 2.0 is smart contracts. Although smart contracts were possible in Bitcoin, there were limitations in creating the desired contract because only the if conditional statement could be used.

On the other hand, Ethereum, which is well-known as a smart contract, can provide Turing completeness, so it can support computer programming, so it can program various types of transactions or contracts.

Existing contracts included legal language in documents printed by legal experts, and reliance on third parties was high. In addition, traditional contracts are time consuming and costly and time consuming as disputes have to rely on the judicial system.

However, blockchain smart contracts can be written in a digital language by computer programmers to define rules and results in the same way as in the existing traditional contracts, specifying the obligations, benefits and fines of the contracting parties, and developed by programming It has the advantage that the contract can be enforced by the system.

According to an embodiment of the present invention, by confirming a transaction rule corresponding to the rating information of the trader who requested the transmission of the cryptocurrency in the smart contract, to determine whether to allow the transmission of the cryptocurrency accordingly, It can improve the transaction stability of currency.

5 is a flowchart illustrating a method of applying a transaction rule of a blockchain-based cryptocurrency according to an embodiment of the present invention.

Referring to FIG. 5, first, a request for transmission of a cryptocurrency is requested (step S500), and rating information of a trader who requested the transmission of the cryptocurrency is checked (step S510).

Here, the cryptocurrency may be any one of various blockchain-based cryptocurrencies, and according to an embodiment of the present invention, the cryptocurrency may be the first cryptocurrency as described with reference to FIGS. 1 to 4.

As described above, the first cryptocurrency can be converted into another cryptocurrency, the second cryptocurrency, and the second cryptocurrency, another cryptocurrency, can be exchanged for real economic value including goods or services such as gold, etc. It may be a cryptocurrency issued on a condition that can be incinerated by payment of real economic value.

The trader may request transmission through the terminal device to trade his own cryptocurrency, and the trader may be given one grade among a plurality of grades each having different authority.

For example, the plurality of ratings may include an owner rating, an investor rating, a general rating, etc., but the present invention is not limited thereto, and more various ratings may be set according to transaction related authority. Can be.

More specifically, the rating information includes an investor rating, and when the verified rating information is an investor rating, the transaction rules of the smart contract may be configured such that the transaction is restricted for at least a part of the cryptocurrency possessed by the trader.

In this case, the rate at which transactions are restricted among cryptocurrency possessed by an investor-level trader decreases over time, and the transaction restriction may be lifted after a certain period of time has elapsed from the start of the holding of cryptocurrency.

In addition, the cryptocurrency that the corresponding trader additionally holds during the transaction limit period before a certain period has elapsed may be limited to the entire transaction during the transaction limit period.

In addition, the rating information further includes a higher investor rating and a general rating, and the cryptocurrency possessed by the trader of the general rating can be transmitted without any transaction restrictions.

However, the trade rules of the smart contract may be configured such that the traders of the general grade receiving cryptocurrency from the traders of the high-ranking investor grade are converted into the investors grade where the trade is restricted as described above.

In addition, the rating information further includes an owner rating and a central bank rating, and an owner-level trader can change the rating of another trader, and a central-bank-level trader can use a smart contract to transmit cryptocurrency only to the owner-level trader. The trading rules of can be configured.

Meanwhile, the rating information may include at least one upper owner level and manager level for managing authority related to the transaction rule, and further include an exchange class capable of transmitting the cryptocurrency without limitation to all levels of traders. Can be.

Rating-related information as described above and transaction rules for each grade (for example, transmission restrictions, etc.) may be included in a smart contract related to the corresponding cryptocurrency, and when a trader requests to transmit cryptocurrency, Depending on the content, the corresponding transaction process can be executed.

When the trader's rating information is confirmed, a transaction rule corresponding to the trader's rating information is checked according to the content of the smart contract related to the corresponding cryptocurrency (step S520).

For example, the transaction rules included in the content of the smart contract may include rating information, cryptocurrency transmission restriction rules for each rating, rating conversion rules, and permission information for each rating.

Thereafter, based on the transaction rule confirmed through the smart contract in step S520, it is determined whether to allow the transmission of cryptocurrency.

6 is a view for explaining an embodiment of a transaction rule according to the trader's rating information.

Referring to FIG. 6, the trader's rating may include an owner, a super investor, an investor, an anonymous, an exchange (CEX), and a central bank, each One of a plurality of ratings as described above may be designated in the electronic wallet of the trader.

Different trading rules may be defined for a plurality of ratings, and thus, the content of the different trading rules for each rating may be included in the smart contract.

For example, a plurality of ratings may differ from each other in which cryptocurrency can transmit cryptocurrency, or in some classes, cryptocurrency transaction-related authority may differ. Can be.

Hereinafter, with reference to FIGS. 7 to 13, the cryptocurrency transmission rule will be described in detail by class.
