Description

{Method for trading blockchain exchange based real electronic wallet and method for trading the same}

The present invention relates to a method for processing a blockchain transaction based on a real transaction electronic wallet based on a cryptocurrency exchange.

Crypto-Currencies, represented by Bitcoin, have a common form of transaction book called Blockchain.

As an overview, the general user downloads the wallet program of the cryptocurrency to his computer and installs it on his computer, which then runs and synchronizes (matches) the blockchain recorded on himself and the network. First, it usually takes about 3 to 7 days because the data reaches tens of gigabytes. After the synchronization is complete, you can create your own address (the concept of an account at the bank) in your wallet and send or receive Bitcoin through that address (in the case of Bitcoin, 34 digits of English starting with 1) It is a combination of letters) and numbers.As a result of the difficulty of this method, many servers do not drop the entire node as a web wallet service (blockchain info, my etherwellet, metamask, etc.).

Here, all cryptocurrencies running on the blockchain system, including Bitcoin, are a pair of keys in the form of 'private key-public key (address)' between users. The public key is the bank's account number. A private key corresponds to a password, which is a pair that fits only with each other. For example, in the case of the Bitcoin QT program (user personal wallet program), the private key is encrypted using the user password and stored in the member computer. In case of Bitcoin exchange web wallet, the private key is encrypted using the user password or the server's sort (SALT) and stored on the server.

As described above, the existing method is a method of storing the private key in the cryptocurrency exchange server 200 or in a member computer.

However, when using the cryptocurrency exchange server 200, the electronic wallet in each member's exchange is not a real electronic wallet on the blockchain, but a wallet operated based on a database (DB). That is, when a member queries his / her account using the cryptocurrency exchange server 200, the registered and stored balance is visible in the server database DB, but the actual balance existing in the address is meaningless to the member. In addition, there is a possibility that insiders related to cryptocurrency exchange security can secretly use the encrypted private key stored on the server by decrypting it.

Accordingly, it is necessary to generate and provide the electronic wallet of each member generated by the cryptocurrency exchange server 200 as a real transaction electronic wallet that can be actually traded on a blockchain, not a database type electronic wallet.

However, if each real-time electronic wallet is provided to registered members of the cryptocurrency exchange server 200, a fee is incurred each time a member makes a block-chain transaction through his real-life electronic wallet, but too much fees for the seller or buyer There is a problem that is burdened.

For example, as shown in FIG. 1, when selling 10 Ethereum held by Seller A, 10 Ethereum sold is purchased as B1 Buyer 5 Ethereum, B2 Buyer 3 Ethereum, B3 Buyer 2 Ethereum , 3 transactions occur, and seller A pays 10 Ethereum for 3 transactions in each city.

Therefore, if a block chain transaction occurs through each member's real transaction electronic wallet in the exchange, a new method is needed to reduce the transaction transfer fee of each member.

Korean Registered Patent 10-1673073

The technical problem of the present invention is to provide a means to reduce the transaction transmission fee when a block chain transaction occurs through each member's real transaction electronic wallet.

An embodiment of the present invention, the cryptocurrency exchange server, the process of providing a real transaction e-wallet for creating a real transaction e-wallet for each blockchain member to be provided for each member; When the transaction including the sale or purchase of cryptocurrency is performed between member terminals in the cryptocurrency exchange server, the cryptocurrency exchange server encrypts the cryptocurrency for each seller's selling request so that the cryptocurrency transfer is performed from the seller's real electronic wallet to the seller's real electronic wallet. A blockchain confirmation request process for requesting a blockchain confirmation to the blockchain network processing server by adding a blockchain transmission fee to the currency; Including the transaction fee processing process for the cryptocurrency exchange server to process the seller and the buyer to jointly pay the transaction transfer fee of the blockchain when the blockchain transaction for the sale confirmation is received from the blockchain network processing server can do.

Seller: In the case of a blockchain transaction with a buyer = 1: 1, the transaction fee processing process charges the buyer the same amount as the blockchain transfer fee as the buyer fee, and receives the purchase amount, exchange fee, and buyer fee process; And a divider fee distribution process in which the buyer fee transferred from the buyer is divided in half and the same is paid to the seller and the buyer.

In the case of a blockchain transaction of seller: buyer = 1: N, the transaction fee processing process imposes the same amount as the blockchain transmission fee to the N buyers, respectively, as the buyer fee, the purchase amount from N buyers, the exchange fee, And a process of receiving a transfer together with a buyer fee; Among [N × Buyer fees] deposited from N buyers, [(N-1) × Buyer fees] are paid to the seller, and the other buyer's fees are divided by 1 / (N + 1) to block the party of the blockchain firm. It may include; the process of distributing the buyer fee equally paid to each seller and buyer.

In the case of a blockchain transaction of seller: buyer = N: 1, the transaction fee processing process imposes the same amount as the blockchain transfer fee as a buyer fee for each blockchain transaction, and the purchase amount, exchange fee, and buyer from the buyer The process of receiving each transfer along with the fees; It may include; a divider fee distribution process of dividing the buyer fee deposited from the buyer by 1 / (N + 1) and paying the same to each seller and buyer who is a party to the blockchain confirmation.

In the case of a blockchain transaction of seller: buyer = N: N, the transaction fee processing process imposes the same amount as the blockchain transmission fee to the N buyers as the buyer fee, respectively, the purchase amount from N buyers, the exchange fee, And a process of receiving a transfer together with a buyer fee; Among the [N × Buyer fees] deposited from N buyers, the amount corresponding to [(N-1) × Buyer fees] is paid to the seller who has additionally paid the transaction transfer fee, and the other buyer's fee is 1 / (N It may include; divider × 2) by a process of distributing the buyer's fee to each seller and buyer who are parties to the blockchain firm.

The process of distributing the buyer fee may be characterized by converting it into a point form that can be used in the cryptocurrency exchange server and accumulating it to the seller and the buyer.

When the blockchain confirmation request is used, the private key of the member requesting the transaction is encrypted and divided into the first divided private key and the second divided private key, and the first divided private key is stored in the cryptocurrency exchange server, and the second divided private key Is stored in the transaction request member terminal, and the blockchain confirmation request process receives the second divided private key from the transaction request member terminal at the request of the blockchain confirmation, and receives the received second divided private key and cryptocurrency. The transaction request decrypted using the first split private key stored in the exchange server can be sent to the blockchain network processing server along with the transaction request information to request the transaction confirmation.

According to an embodiment of the present invention, when a block chain transaction occurs through an actual electronic wallet of each member in the exchange, it is possible to reduce the transaction transmission fee of each member.

Since the actual transmission of ordinary cryptocurrencies requires a number of confirmation processes, it is impossible to purchase and sell frequently within a short time with this method. In order to solve this problem, the transaction system of the present invention creates an electronic wallet (hereinafter referred to as a 'real transaction electronic wallet') that can actually perform a blockchain transaction on the exchange server, and uses this real transaction electronic wallet to quickly and stably block blockchain transactions. The action is made so that a quick response is possible with real-time processing of orders / contracts.

To this end, the actual transaction electronic wallet-based transaction system in the cryptocurrency exchange of the present invention, a wired / wireless communication network (not shown), a member terminal 300, a cryptocurrency exchange server 200, and a blockchain network as shown in FIG. It may include a processing server 100.

Hereinafter, cryptocurrency is a concept including all of various digital cryptocurrencies such as Bitcoin, Bitcoin Cash, Ethereum, Litecoin, Namecoin, Dogecoin, and Ripple, which are traded on exchanges.

The wired / wireless communication network (not shown) provides wired communication or wireless communication between the member terminal 300 and the cryptocurrency exchange server 200, and between the cryptocurrency exchange server 200 and the blockchain network processing server 100. When the wired / wireless communication network (not shown) is implemented as a wireless communication network, a wireless mobile communication network consisting of a base transceiver station (BTS), a mobile switching center (MSC), and a home location register (HLR) You can use for data communication. In addition, when the wired / wireless communication network (not shown) is implemented as a wired communication network, it may be implemented as a network communication network. Data communication may be performed according to an Internet protocol such as Transmission Control Protocol / Internet Protocol (TCP / IP).

The member terminal 300 is a terminal used by a member registered in the cryptocurrency exchange server 200, and in the drawing, a smartphone is described as an example, but a desktop PC and a tablet as well as a smartphone are described. It may be a PC (tablet PC), a slate PC (slate PC), a notebook computer (notebook computer), and the like. Of course, the terminal to which the present invention is applicable is not limited to the above-described types, and it is natural that it can include all terminals capable of communicating with external devices.

Member terminal 300, a cryptocurrency trading app (APP; application) is installed, accesses the cryptocurrency exchange to display cryptocurrency transaction information, and also cryptocurrency transaction (cryptocurrency) on the cryptocurrency exchange server 200 (Sell or Buy).

For example, the member terminal 300 is equipped with a blockchain-based cryptocurrency transaction app that transmits a transaction request signal including the amount information of the cryptocurrency to be sold and personal information of the trader to the cryptocurrency exchange server 200. Terminal. Here, the blockchain-based cryptocurrency trading app is an application program, and can be downloaded and installed by accessing the App Store through the member terminal 300 or directly downloading and installing the blockchain-based digital cryptocurrency exchange server 200.

For reference, the cryptocurrency exchange server 200 requests the blockchain confirmation according to the transaction request signal to the blockchain network processing server 100. Here, the blockchain confirmation is a message requesting that the transaction including the amount information of the cryptocurrency to be sold and the personal information of the trader is recorded on the blockchain and confirmed, and the blockchain network processing server 100 trades Perform the requested blockchain confirmation.

In addition, on the member terminal 300, a blockchain-based digital cryptocurrency transaction screen for performing an input of an amount of a digital cryptocurrency having a blockchain and selection of an instant messenger is displayed. The cryptocurrency transaction screen may include an amount display field in which the amount of the cryptocurrency having the blockchain is displayed.

In addition, the member terminal 300 may include a seller terminal 300a and a buyer terminal 300b. Hereinafter, a terminal for selling a cryptocurrency is called a seller terminal 300a, and a terminal for buying a cryptocurrency is a buyer terminal ( 300b).

When the blockchain transaction confirmation is requested from the cryptocurrency exchange server 200, the blockchain network processing server 100 propagates the blockchain transaction based on the transaction request information to an adjacent node, thereby confirming the blockchain transaction (cicada authentication and recording ), And notifies the cryptocurrency exchange server 200 of the completion of the blockchain transaction confirmation. For example, the Bitcoin blockchain network processing server 100 exchanges 6 confirmations with adjacent nodes per 1 blockchain transaction and performs a blockchain confirmation that completes the transaction.

To this end, the blockchain network processing server 100 performs a blockchain-based cryptocurrency transaction by verifying the transaction information for the cryptocurrency transaction with the transmitted blockchain when the transaction information for the cryptocurrency transaction with the blockchain is transmitted. A blockchain is recorded in which transaction information for cryptocurrency transactions having a blockchain is recorded according to the authentication. Therefore, when trading cryptocurrency with blockchain, it is based on peer-to-peer network (P2P) that performs cryptocurrency transaction with blockchain through confirmation (authentication and record) of cryptocurrency transaction with blockchain. These are the devices that make up the distributed blockchain network. In particular, in the present invention, in the configuration constituting the blockchain network processing server 100, an electronic wallet for each individual member operated by a cryptocurrency exchange corresponds as a member of one blockchain network processing server 100.

The cryptocurrency exchange server 200 generates and provides a real transaction electronic wallet for each member to perform blockchain transactions. In the past, an electronic wallet in which a blockchain transaction can actually be made is managed as a database instead of being generated to each member, but the cryptocurrency exchange server 200 of the present invention generates an electronic wallet in which each member can actually make a blockchain transaction. to provide.

Therefore, the cryptocurrency exchange server 200 deducts the amount of money that is sold from the blockchain-based cryptocurrency amount information held in the seller's actual transaction e-wallet, and the deducted amount by the buyer's actual transaction e-wallet. It generates transaction information for digital cryptocurrency transactions that consists of transaction details that are accumulated in the amount information, and is transmitted to the blockchain network processing servers 100.

In particular, the cryptocurrency exchange server 200 of the present invention, when the blockchain transaction for the sale confirmation is completed, the cryptocurrency exchange server 200 is processed such that the seller and the buyer jointly bear the transmission fee of the blockchain, It prevents excessively charged transfer fees on either side, ultimately reducing the blockchain transaction fee.

To this end, the cryptocurrency exchange server 200 of the present invention includes a real transaction electronic wallet 210 for each member and a blockchain transaction processing unit 220 as shown in FIG. 3. In addition, the partitioned private key storage unit 230 in which the member's private key is stored may be further included. In addition, although not shown, the blockchain-based cryptocurrency exchange server 200 includes information registered by the user at the time of membership registration for the transaction of the blockchain-based cryptocurrency, including the member's ID, password, and telephone number including the telecommunication terminal. Includes a member list information DB (not shown) in which member identification information including an address is stored for each member.

The actual transaction e-wallet 210 for each member is an electronic wallet having blockchain-based cryptocurrency amount information so as to actually trade cryptocurrency on the blockchain, and is generated and allocated for each member. Therefore, when a blockchain transaction transaction occurs, the blockchain transaction history is updated and stored in each member's real transaction electronic wallet.

The block chain transaction processing unit 220 requests a block chain confirmation, which is requested to sell, to the block chain network processing server 100 when there is a request to sell or buy a block chain from a member.

When a transaction including the sale or purchase of cryptocurrency is made between the member terminals 300 in the cryptocurrency exchange server 200, the cryptocurrency exchange server 200 transfers the cryptocurrency from the seller's actual transaction electronic wallet to the buyer's actual transaction electronic wallet. In order to pay, the block chain transmission fee is added to the cryptocurrency according to the seller's request to sell, and the blockchain network processing server 100 requests the blockchain confirmation. In addition, when the blockchain transaction for the sale confirmation is received from the blockchain network processing server 100, the cryptocurrency exchange server 200 processes the seller and the buyer to jointly pay the transaction transfer fee of the blockchain. Detailed description of the transaction processing of the transaction transfer fee will be described in detail with reference to FIGS. 5 to 10 to be described later.

On the other hand, in realizing a real-time electronic wallet-based blockchain transaction processing in the cryptocurrency exchange of the present invention, it is necessary to improve security and make decentralized transactions. To this end, as shown in FIG. 4, the private key of the member requesting the transaction used when requesting the blockchain confirmation is encrypted and divided into the first divided private key and the second divided private key, so that the first divided private key is a cryptocurrency exchange server ( 200) is stored in the divided private key storage unit 230, and the second divided private key is stored in the transaction request member terminal 300. Then, upon request of the blockchain confirmation, the second private key is received from the transaction request member terminal 300, and the received second private key and the private key storage unit 230 of the cryptocurrency exchange server 200 are received. The transaction key decrypted using the stored first partitioned private key is restored, and the private key of the member is restored and transmitted to the blockchain network processing server 100 together with the transaction request information to request a transaction confirmation.

For reference, referring to FIG. 4, a separate encryption security server 400 is responsible for encrypting and splitting the first divided private key and the second divided private key. In addition, by providing a separate security service server 500, the partitioned encryption key can be reissued after authentication of the member information to the lost member.

5 is a flowchart showing a process of processing a blockchain transaction based on a real transaction electronic wallet in a cryptocurrency exchange according to an embodiment of the present invention, and FIG. 6 is a 1: 1 blockchain between a seller and a buyer according to an embodiment of the present invention An example picture in which a transaction is made, and FIG. 7 is an example picture in which a 1: N blockchain transaction is performed between a seller and a buyer according to an embodiment of the present invention, and FIG. 8 is an N: 1 between a seller and a buyer according to an embodiment of the present invention. An example illustration of a blockchain transaction, and FIG. 9 is an example illustration of a N: N blockchain transaction between a seller and a buyer according to an embodiment of the present invention, and FIG. 10 is a cryptocurrency other than Korean won according to an embodiment of the present invention. This is an example of a fee when purchasing cryptocurrency.

The method for processing a blockchain transaction based on a real transaction electronic wallet in the cryptocurrency exchange of the present invention provides a real transaction electronic wallet providing process (S510), a blockchain confirmation request process (S520), and a transaction fee processing process as shown in FIG. 5 ( S530).

The real transaction electronic wallet providing process (S510) is a process in which the cryptocurrency exchange server 200 generates a real transaction electronic wallet in which blockchain transactions can be made and provided for each member. The actual transaction e-wallet 210 for each member becomes a blockchain component capable of confirming (authenticating and recording) the blockchain by participating in the blockchain network.

In the block chain confirmation request process (S520), when a transaction including the sale or purchase of cryptocurrency is made between member terminals 300 in the cryptocurrency exchange server 200, the cryptocurrency exchange server 200 is in the seller's real transaction electronic wallet. This is a process of requesting a blockchain confirmation from the blockchain network processing server 100 by adding a blockchain transfer fee to the cryptocurrency for each seller's request to sell, so that the cryptocurrency transfer can be made to the buyer's real transaction electronic wallet. For example, as shown in FIG. 6, when the seller sells 1 Ethereum cryptocurrency, the block network network processing server 100 generates 1ETH of the transfer transmission fee of 0.000441ETH, resulting in a block of 1.0.000441ETHH in total. A chain confirmation request is issued.

In the transaction fee processing process (S530), when the blockchain transaction for the sale confirmation is received from the blockchain network processing server 100, the cryptocurrency exchange server 200, the seller and the buyer jointly trade the blockchain It is processed to bear the transmission fee.

For example, as shown in FIG. 1, when selling 10 Ethereum held by Seller A, 10 Ethereum sold is purchased as B1 Buyer 5 Ethereum, B2 Buyer 3 Ethereum, B3 Buyer 2 Ethereum , 3 transactions occur, and seller A pays 10 Ethereum for 3 transaction transfer fees to each city, and pays excessive transaction fees.

In order to improve this problem, the present invention is to deal with the seller and the buyer to jointly bear the transaction transfer fee of the blockchain.

The dynamic payment method of the transaction transmission fee can be made in various forms such as 1: 1 transaction (FIG. 6), 1: N transaction (FIG. 7), N: 1 transaction (FIG. 8), and N: N transaction (FIG. 9). have. It will be described in detail below.

1) 1: 1 transaction (Figure 6)

As shown in FIG. 6, in the case of a blockchain transaction of seller: buyer = 1: 1, the transaction fee processing process of the cryptocurrency exchange server 200 (S530) is the buyer of the same amount as the blockchain transmission fee as the buyer fee Includes the process of depositing the amount to the buyer, the exchange fee, and the buyer's fee, and thereafter, the process of distributing the buyer's fee, which divides the buyer's fee transferred from the buyer in half and pays the seller and the buyer the same. can do.

For example, as shown in FIG. 6, it is assumed that the seller A1 applies for 1ETH, which is 1 Ethereum, and the buyer B1 requests to buy 1ETH.

A1 In addition to the 1ETH you wish to sell, the seller's actual transaction electronic wallet adds a transaction transfer fee of 0.000441ETH to request a blockchain sale confirmation to the blockchain network processing server.

B1 The buyer deposits 661 won corresponding to the transaction transfer fee of 0.000441ETH into the cryptocurrency exchange in addition to the purchase amount of 1ET500,000 of 1ETH and 2,250 won of the exchange brokerage fee at the time of the application for purchase.

After completing the blockchain confirmation, the blockchain network processing server deposits 1ETH minus the transaction transfer fee of 0.000441ETH from the seller's 1.0.000441ETHH into the B1 buyer's real transaction electronic wallet.

When the transaction is completed, the cryptocurrency exchange server 200 pays A1 seller and B1 buyer 3333 won divided by 1/2 of the buyer fee 661 won additionally deposited from the B1 buyer.

In the form of payment, it can be converted into a point form that can be used in the cryptocurrency exchange server 200 to accumulate to sellers and buyers, and if it is accumulated over a certain amount, it can be refunded and paid in cash, gift certificates, etc.

2) 1: N transaction (Figure 7)

As shown in FIG. 7, in the case of a blockchain transaction of seller: buyer = 1: N, the transaction fee processing process (S530) of the cryptocurrency exchange server 200 is the same as the blockchain transmission fee, N [(N-1) × Buyer fees among [N × Buyer fees], which are charged to each buyer and transferred from N buyers along with the purchase amount, exchange fees, and buyer fees, respectively, and [N × Buyer fees] deposited from N buyers ] To the seller, and divide the remaining one buyer's fee by 1 / (N + 1) by the same amount to each seller and seller who is a party to the blockchain firm.

For example, as shown in FIG. 7, it is assumed that seller A requests to sell 13ETH, buyer B1 purchases 6ETH, buyer B2 requests 4ETH, and buyer B3 requests 3ETH. Then Seller: Buyer = 1: N, N becomes '3'.

In addition to the 13ETH that the seller wants to sell, the transaction transfer fee due to the blockchain confirmation between B1 buyers and the transaction transfer fee due to the blockchain confirmation between B2 buyers and the transaction transfer fee due to the blockchain confirmation between B3 buyers A transfer fee of 0.000441 ETH is added, resulting in a total transaction fee of 3 × 0.000441 ETH.

The buyer of B1 deposits 661 won corresponding to the transaction transfer fee of 0.000441ETH in addition to the purchase amount of 6ETH and the exchange brokerage fee to the cryptocurrency exchange at the time of the application for purchase.

Similarly, the buyer of B2 deposits 661 won corresponding to the transaction transfer fee of 0.000441ETH in addition to the purchase amount of 4ETH and the exchange brokerage fee to the cryptocurrency exchange upon purchase application.

Likewise, the buyer of B2 deposits 661 won corresponding to the transaction transfer fee of 0.000441ETH in addition to the purchase amount of 3ETH and the exchange brokerage fee at the time of the application for purchase to the cryptocurrency exchange.

The blockchain network processing server deposits ETH, which is the transaction transfer fee of 0.000441 ETH, for each transaction after the completion of the blockchain confirmation, into each of the B1, B2, and B3 buyers' actual transaction electronic wallets. In other words, 6ETH is deposited into the B1 buyer's actual transaction e-wallet, B2 buyer's actual transaction e-wallet is deposited into 4ETH, and B3 buyer's actual transaction e-wallet is deposited into 3ETH.

When the transaction is completed, the cryptocurrency exchange server 200 provides [2 × 661], which is [(N-1) × buyer fee], from the buyer's fee of 3 × 661, which is additionally deposited from the buyers B1, B2, and B3. Pay as a cashback. In addition, [661 won / 4] won divided by 1/4 of the remaining buyer's fee after the cashback is paid is equally paid to seller A, buyer B1, buyer B2, and buyer B3.

Similarly, as a payment form, the cryptocurrency exchange server 200 can be converted into a point form that can be used and accumulated to the seller and the buyer, and if a certain amount or more is accumulated, it can be refunded and paid in cash or gift certificates.

3) N: 1 transaction (Figure 8)

As shown in FIG. 8, in the case of a blockchain transaction of seller: buyer = N: 1, the transaction fee processing process (S530) imposes the same amount as the blockchain transmission fee as a buyer fee for each blockchain transaction, The process of receiving the purchase amount, the exchange fee, and the buyer fee from the buyer, and the buyer fee deposited from the buyer, divided by 1 / (N + 1), is the same for each seller and buyer who is a party to the blockchain firm. There is a process of distributing buyer fees.

For example, as shown in FIG. 8, it is assumed that the seller A1 requests to sell 3ETH, the seller A2 requests to sell 5ETH, the seller A3 requests to sell 2ETH, and the buyer B requests to buy 10ETH. . Then Seller: Buyer = N: 1 to N becomes '3'.

In addition to the 3ETH you wish to sell, A1 seller's actual transaction electronic wallet generates 0.000441ETH of transaction transfer fee due to the blockchain confirmation between the B buyers. Likewise, A2 seller's actual trading electronic wallet generates a transaction transfer fee of 0.000441ETH due to the blockchain confirmation between the B buyers in addition to 5ETH to be sold, and A3 seller's actual trading electronic wallet causes the blockchain confirmation between B buyers in addition to the 2ETH they want to sell. Transaction transfer fee 0.000441 ETH is generated and generated.

B, the buyer, in addition to the purchase amount of 10ETH and the exchange brokerage fee, deposits 661 won, which corresponds to the transaction transfer fee of 0.000441ETH, to the cryptocurrency exchange at the time of the purchase request.

The blockchain network processing server deposits ETH, which is the transaction transfer fee of 0.000441 ETH, for each transaction, after the completion of the blockchain confirmation, into the B-buyer's real transaction electronic wallet, respectively.

When the transaction is completed, the cryptocurrency exchange server 200 divides the buyer's fee 661 won, which is additionally deposited from the buyer B, into a quarter of [661 won / 4] won to the A1 seller, the A2 seller, the A3 seller, and the B buyer. Pay the same.

Similarly, as a payment form, the cryptocurrency exchange server 200 can be converted into a point form that can be used and accumulated to the seller and the buyer, and if a certain amount or more is accumulated, it can be refunded and paid in cash or gift certificates.

4) N: N transaction (Figure 9)

As shown in FIG. 9, in the case of a blockchain transaction of seller: buyer = N: N, the transaction fee processing process (S530) imposes the same amount as the blockchain transmission fee on N buyers, respectively, as a buyer fee, The amount of money corresponding to [(N-1) × Buyer fee] among the [N × Buyer fee] deposited from N buyers and the process of receiving the purchase amount, exchange fee, and buyer fee from N buyers, respectively. The seller pays the transaction transfer fee additionally. In addition, there is a process of distributing the buyer's fees by dividing the remaining buyer's fees by 1 / (N × 2) and paying the same to each seller and buyer who is a party of the blockchain firm.

For example, as shown in FIG. 9, the seller A1 applies to sell 10ETH, the seller A2 applies to sell 1ETH, the seller A3 applies to sell 2ETH, the seller B1 requests to buy 5ETH, and the seller B2 Assume that 3ETH is requested to be purchased and B3 buyer is requested to buy 5ETH. Then Seller: Buyer = N: N, N becomes '3'.

A1 Seller's actual transaction In addition to 10ETH that you want to sell, in addition to 10ETH you want to sell, transaction transfer fee due to 5ETH transaction between buyers B1 and 0.000441ETH due to 3ETH transaction between sellers B2 and 0.000441ETH due to 3ETH transaction between sellers, and transaction transfer fee due to 5ETH transaction between B3 sellers and 0.000441ETH Is generated, resulting in a total of 3 × 0.000441 ETH transaction transfer fee.

A2 The seller's actual transaction electronic wallet generates a transaction transfer fee of 0.000441ETH once in addition to the 1ETH you wish to sell, and similarly, the seller's actual transaction electronic wallet generates a transaction transfer fee of 0.000441ETH once in addition to the 2ETH sale.

B1 The buyer deposits KRW 661 corresponding to the blockchain transaction transfer fee of 0.000441ETH in addition to the purchase amount of 5ETH and the exchange brokerage fee at the time of application for purchase as a buyer fee to the cryptocurrency exchange.

B2 The buyer, in addition to the purchase amount of 3ETH and the exchange brokerage fee at the time of the purchase request, deposits 661 won corresponding to the blockchain transaction transfer fee of 0.000441ETH as a buyer fee into the cryptocurrency exchange.

The B3 buyer deposits 661 won corresponding to the blockchain transaction transfer fee of 0.000441ETH, in addition to the 5ETH purchase amount and the exchange brokerage fee, into the cryptocurrency exchange at the time of the purchase request.

The blockchain network processing server deposits ETH, which is the transaction transfer fee of 0.000441 ETH, for each transaction, after the completion of the blockchain confirmation, to each buyer's real transaction electronic wallet. That is, 5ETH is deposited into the actual transaction e-wallet of the B1 buyer, 3ETH is deposited into the e-wallet of the B2 buyer, and 5ETH is deposited into the e-wallet of the B3 buyer.

When the transaction is completed, the cryptocurrency exchange server 200 trades [2 × 661], which is [(N-1) × buyer fee], among 3 × 661 won of buyer fees that are additionally deposited from B1, B2, and B3 buyers. Payment is made as a cashback to the seller of A1 who paid the transmission fee additionally

And A1, A2, which are parties to the blockchain firm, are divided by 1 / (N × 2) = 1 / (3 × 2) = 1/6 by dividing the remaining buyer's fee of 661 after cashing back to A1 seller. The same is paid to sellers A3 and B1, B2, and B3.

Similarly, as a payment form, the cryptocurrency exchange server 200 can be converted into a point form that can be used and accumulated to the seller and the buyer, and if a certain amount or more is accumulated, it can be refunded and paid in cash or gift certificates.

On the other hand, in the above description, although an example of buying a cryptocurrency using KRW (KRW) has been described, a transaction using electronic money may occur instead of KRW (KRW) transaction. That is, there may be a case where the seller A sells the first cryptocurrency in the real transaction e-wallet and purchases the second cryptocurrency with the amount sold.

Even in this case, A receives a commission for each number of purchases and purchases, and processes the cashback and credit points. That is, as shown in FIG. 10, when member A requests a transaction for exchanging 10 bitcoins (BTC) into 20 Ethereum (ETH), transaction transfer fees are generated in each 10 bitcoin town, and 20 Ethereum When buying, a purchase fee corresponding to the transaction transmission fee is generated. From the position A, there are two transmission fees (transaction transfer fee in the Bitcoin sales city + buyer's fee when purchasing Ethereum), but the remaining fees can be accumulated.

In other words, cash back is paid to A who sold Bitcoin (661 won x 2), and the remaining buyer fee is divided into 1/4 to divide points into A, B1, B2, and B3. In addition, the buyer's fee provided by A when purchasing Ethereum is divided into 1/2 to earn points to A and C.

On the other hand, the private key of the member requesting the transaction used when requesting the blockchain confirmation is encrypted and divided into the first divided private key and the second divided private key, and the first divided private key is stored in the cryptocurrency exchange server 200, The second divided private key may be stored in the transaction request member terminal 300.

In this case, the blockchain confirmation request process, upon requesting the blockchain confirmation, receives the second divided private key from the transaction request member terminal 300, and receives the received second divided private key and cryptocurrency exchange server 200. The transaction request decrypted using the stored first partitioned private key may be transmitted to the blockchain network processing server 100 together with the transaction request information to request the transaction confirmation.

Therefore, in processing a real-time electronic wallet-based blockchain transaction in the cryptocurrency exchange of the present invention, security can be improved and decentralized transactions can be made.

The above-described embodiments in the description of the present invention are selected and presented as the most preferable examples to help those skilled in the art from among various possible examples, and the technical spirit of the present invention is not necessarily limited to or limited by these embodiments. , Various changes and modifications and other equivalent embodiments are possible without departing from the technical spirit of the present invention.
