Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be embodied in various different forms, and the present embodiments only make the disclosure of the present invention complete, and those of ordinary skill in the art that It is provided to fully inform the skilled worker of the scope of the invention, which is defined only by the scope of the claims.

Cryptocurrency, also known as cryptocurrency, includes Bitcoin, Ethereum, Litecoin, Ripple, Bitcoin Cash, EOS, Stella, Ada, etc. There are hundreds and thousands of coins.

Such virtual currency has a value of a certain amount of cash, and the act of buying and selling is being made. Until now, there is a problem that the method of trading virtual currency is limited to using an exchange.

This is because the cryptocurrency is encrypted with a blockchain, and each wallet address is used for transmission. If a wrong transmission (such as a wallet address error) is made, it may be very difficult to reverse it or there may be no way to return it. to be.

Because of the security of blockchain, virtual currency trading between individuals can be dangerous, so most people only trade virtual currency through exchanges.

Thus, in order to solve the above problems, the present invention is to propose a method that can safely proceed with the virtual currency transactions between individuals.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart of a method for providing a virtual currency transaction between individuals according to an embodiment of the present invention.

Referring to Figure 1 will be described with respect to the flow of a method for providing a virtual currency transactions between individuals according to an embodiment of the present invention.

First, the server receives the cryptocurrency from the seller client. (Step S510)

More specifically, the server receives the virtual currency sales bulletin from the seller client, and receives the virtual currency for sale from the seller client to the wallet address of the server. More specifically, it is sent from the merchant client's wallet to the server's wallet address.

This process is as follows. The seller client connects to the server to post cryptocurrency and posts the sale.

Accordingly, the server receives a country from which the seller client will sell the virtual currency, the type of the virtual currency, the sales quantity, the selling price, and the like, and the bank account number for receiving the transaction amount.

In addition, since the seller and the buyer do not directly exchange cryptocurrencies, but transmit the virtual currency through the server, the server receives the virtual currency for the transaction from the seller client.

In this case, since a transaction is canceled, the server receives a virtual currency address to recover the virtual currency of the sale from the seller client. Therefore, if a sale transaction registered by the seller client is canceled, the server transmits the corresponding virtual currency to the virtual currency address inputted from the seller client.

The server encrypts and stores the information of the seller client, the information of the sales article, the virtual currency type, the number, the amount of the sales article, the virtual wallet wallet address of the seller client, and the virtual currency received from the seller client. .

To this end, step S510 may further include the server requesting the seller client's cryptocurrency wallet address input to the seller client, and the server providing the seller client's virtual currency wallet address.

At this time, in the server providing the virtual currency wallet address of the server to the seller client, by providing the QR code to the seller client, the virtual currency wallet address of the server can be automatically loaded by reading the QR code. As a result, it is possible to prevent a mistake in inputting an address.

Next to step S510, the server receives a sale of one of the cryptocurrency sales list from the buyer client. (Step S520)

The server stores a list of sales registered by a number of different sellers, and a buyer client accessing the server can check the sales list of the server and select a sale that he / she wants to trade.

At this time, each sale (sale post) may include information such as seller client information, the title of the post, the type of virtual currency, number, amount.

In addition, more detailed information about each seller (sales post) seller client may be included, and may include the ID of the seller client, the total number of transactions, the number of problem occurrences, and the evaluation scores of traders. One reliability can be expressed.

For example, if the total number of transactions of the seller client Seller1 is 60 and the number of problem occurrences is two, it may be calculated and expressed as 96% of reliability.

In addition, the reliability may be calculated by including a valuation index received from buyer clients who have previously made transactions.

Through this, a client whose reliability is less than or equal to a predetermined point may limit a transaction, and by separately designating a special management object in a server, it may prevent a problem in a transaction between the clients.

This is because a client with low reliability has a higher probability of conducting a malicious transaction.

The buyer client clicks on the sale and checks the type, quantity, price and fee of the cryptocurrency.

In this case, the fee refers to the price of providing a transaction in the server, and may receive a predetermined percentage of the corresponding cryptocurrency as a fee, may receive a fee in cash such as won and dollars, or may utilize various coupons and points. have.

Then, the server receives from the buyer client an address to receive the cryptocurrency after the transaction is completed.

In addition, the server may receive the account number of the main bank for the transaction at the time of sale, purchase from the buyer client. In this case, the server may place a predetermined limit for the security and reliability of the virtual currency transaction, such as granting an approval only when the real name of the client and the account holder of the corresponding account are the same for the security of the transaction.

Next, in step S520, the server opens an encrypted chat room, and enters the seller client in which the purchaser client and the seller client who have selected the sales cases selected from the buyer client into the opened chat room. (Step S530)

At this time, the chat room is encrypted and opened to secure the transaction, and may be used as a means for the buyer and seller to negotiate the price by confirming the purchase intention by performing a chat (communication).

At this time, the UI of the chat room may provide a function for checking the corresponding sales information, the information of the buyer client, the information of the seller client, how to use instructions, precautions, etc., and select the functions provided by the UI and the language of the information. Can provide the ability to:

In addition, the chat room may include a deposit complete button and a request for arbitration button. By entering such a button, the client can provide information to the server and request to perform a function.

In step S530, the server receives a deposit confirmation from the client. (Step S540)

More specifically, the server includes receiving a payment confirmation from the buyer client and the server receiving a payment confirmation from the seller client.

In step S530, when the bargain between the buyer and the seller in the chat room, the purchase intention is confirmed, the buyer client will transfer the amount corresponding to the sale to the seller client's account.

Accordingly, the buyer client selects / clicks the deposit confirmation button indicating that the user has deposited the corresponding amount, and the server receives the deposit confirmation from the buyer client.

In addition, the server may provide a message to the seller client to confirm the deposit since the purchaser made a deposit.

Accordingly, the seller client checks his registered bank account and checks that the deposit is properly made, selects / clicks the deposit confirmation button, and the server receives the deposit confirmation from the seller client.

In one embodiment, when the server receives the payment confirmation from the buyer client, the seller client, the server may output a message informing the chat room of the payment confirmation.

Next, in step S540, the server transmits the corresponding virtual currency to the wallet address of the buyer client. (Step S550)

In step S530, the server receives a deposit confirmation from the buyer client and the seller client, determines that the transaction amount has been deposited between the buyer and the seller, and converts the corresponding virtual currency (the virtual currency received from the seller client) into the wallet address of the buyer client. To be sent to.

When these processes are completed, the server determines that all of the transaction process is finished, and terminates the chat room.

At this time, even after the transaction is completed, the problem may be raised according to a specific situation, so that the sales information, the buyer client, the information of the seller client, chat contents of the chat room, etc. may be encrypted and stored in the server.

In one embodiment, the method for providing an individual-to-person virtual currency transaction according to an embodiment of the present invention may further include providing an arbitration mode, which allows the buyer client and seller client to negotiate a price in a chat room, In the process of confirming the purchase intention, it may be initiated at the request of the buyer client or the seller client.

Therefore, the following steps may proceed between steps S530 and S540, which will be described in more detail below.

The server receives a mediation request from a buyer client or a seller client. (Step S532)

In this case, the arbitration request may occur in various cases, such as a conflict between the buyer and the seller, a price bargaining is not made, a fraudulent intention (a malicious intention), and the like.

For example, if you're a buyer-check deposit completed without making a deposit, and ask the seller to confirm the deposit,

In the case of the seller-There may be various cases such as the case of confirming the completion of the deposit and not requesting the confirmation of the deposit and requesting the deposit continuously.

In step S532, the server proceeds with the mediation mode of the transaction between the buyer client and the seller client according to a predetermined arbitration scenario. (Step S534)

The server proceeds to mediation mode to resolve the situation according to the application status case of the client who applied for mediation mode.

Therefore, it is preferable that a method of proceeding the arbitration scenario is set and stored in the server according to each situation.

In step S534, if the server succeeds in arbitration between the buyer client and the seller client, the server completes the mode of arbitration, and if the server detects a fraudulent intention in the transaction of the buyer client or the seller client, the client takes the preset action. do. (Step S536)

In more detail, when the server succeeds in arbitration between the buyer and the seller, the mediation mode is completed and the buyer and the seller can proceed to step S540.

However, if the server detects the buyer's or seller's intention of fraud (malicious intention), the client can take appropriate action.

For example, if it is clear that the buyer client has deposited the money into the seller client's account, the server will mediate the seller client to verify the account once more, and if the seller client confirms the deposit, the mediation was determined to be successful. do.

However, if the seller's client does not deposit continuously, the server checks the deposit process in more detail, and if the seller's malicious intention is seen, cancels the transaction and according to the degree of the intention It can take steps such as downgrading, pausing, permanently stopping, or leaving permanently.

In the course of transactions between sellers and buyers, tangible goods and deposits of cash are relatively easy to be reversed in case of suspected fraud even after the transaction is made, such as returning goods or money, but in the case of virtual currency In addition, since the transmission is encrypted by the blockchain, once the cryptocurrency is transferred, the process of returning it can be very difficult.

Accordingly, by providing such an arbitration mode, risks are eliminated before the transfer of virtual currency is made, thereby enabling secure transactions between individuals.

According to an embodiment of the present invention, a method of providing a virtual currency trading between individuals provides a virtual currency trading between individuals to sellers and buyers who have been forced to trade virtual currency through an exchange.

In this case, when the seller and the buyer directly transmit the virtual currency, a number of damages may occur due to the mistakes of the clients and the fraud on the malicious client.

Therefore, when the server receives and stores the cryptocurrency from the seller client, and the deposit between the seller and the buyer is confirmed, the server transmits the cryptocurrency to the buyer's client's cryptocurrency wallet address, thereby preventing the above damage from occurring. There is.
