Description

How to operate a cryptocurrency exchange's interlocking transaction with other exchanges{Method for operating a crypto-currency exchange}

The present invention relates to a method of operating a cryptocurrency exchange, and more particularly, to a method of operating a cryptocurrency exchange linked to other exchanges.

Cryptocurrencies represented by Bitcoin have a common type of transaction ledger called Blockchain. General users download cryptocurrency electronic wallet programs to their computers. And install it on your computer. Then, as the cryptocurrency electronic wallet program runs, it first starts to synchronize and match itself with the blockchain recorded on the network. Since the data is in the tens of gigabytes, it usually takes a few days. After the synchronization is over, the bank can create its own address corresponding to the concept of the account in its wallet and receive or transmit cryptocurrency through that address. In the case of bitcoin among cryptocurrencies, the address is a combination of 34 English digits starting with 1 and numbers. Due to the difficulty of this method, services in which the server with all nodes does not drop the entire node as an electronic wallet service are also implemented in Blockchain Info, MyEtherWallet, and Metamask.

Here, all cryptocurrencies (Crypto-Currency) running in the blockchain system, including bitcoin, are a pair of keys corresponding in the form of'private key-public key (address)' between users. The public key corresponds to the bank account number and the private key corresponds to the password, which is a pair that only fits each other. For example, in the case of a cryptocurrency electronic wallet program, the private key is encrypted using a user password and stored in the member computer. In the case of a Bitcoin electronic wallet, the private key is encrypted using the user password or the server's SALT and stored on the server. As such, the conventional method is to store the private key on the server of the cryptocurrency exchange or on the member computer. .

However, when using a cryptocurrency exchange server, each member's electronic wallet is not an actual electronic wallet on the blockchain, but a wallet operated based on a database (DB). That is, when a member searches his/her account using a cryptocurrency exchange server, the registered and stored balance in the server database (DB) is visible, 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 decrypt the corresponding encrypted private key stored in the server and use it secretly.

Accordingly, it is necessary to generate and provide the electronic wallet of each member generated on the server of the cryptocurrency exchange as an electronic wallet that can actually be transacted on the blockchain, not as an electronic wallet in the form of a database.

In addition, in the conventional cryptocurrency exchange, the types of cryptocurrencies that can be traded for each cryptocurrency exchange are limited. Therefore, in order for members to trade various cryptocurrencies, there was a disadvantage that they had to access and trade multiple exchanges.

The present invention has been devised in view of the above, and allows a member to access a single exchange system to check price information for various cryptocurrencies of other exchanges associated with it, and to sell and buy in real time. Provides a cryptocurrency exchange system that enables members to purchase cryptocurrency at a lower price and sell cryptocurrency at a higher price by checking the market price difference between various exchanges and a method of operating a cryptocurrency exchange's interlocking transaction with other exchanges. It aims to do.

In the cryptocurrency exchange system according to an aspect of the present invention for solving the above problem, the price of cryptocurrencies sold at one or more other exchanges associated with the cryptocurrency is initiated, and the member's purchase or sale of cryptocurrencies of the other exchanges When the request is received, it is possible to buy or sell the cryptocurrency of the other exchange to the member.

It is possible to provide price information of cryptocurrencies sold by the other exchanges.

It is possible to compare and provide price information by exchange for a specific cryptocurrency.

Among the other exchanges, information on an exchange indicating the highest price and the lowest price for a specific cryptocurrency may be provided.

When receiving the completion of the block chain transaction for the purchase or sale confirmation in the member electronic wallet from the blockchain network processing server, the cryptocurrency exchange server can process the seller and the buyer to jointly bear the transaction transmission fee of the blockchain.

When receiving the completion of a block chain transaction for confirmation of purchase or sale in the member electronic wallet from the blockchain network processing server, the cryptocurrency exchange server is the ratio of the plurality of types of cryptocurrencies deposited in each exchange reserve You can have the fee divided according to.

Another aspect of the present invention for solving the above problem is a method of operating a cryptocurrency exchange interlocking transaction with other exchanges, in the method of operating a cryptocurrency exchange system, a plurality of exchanges of a plurality of exchanges in a cryptocurrency exchange through linkage between exchanges. Starting each price information of the cryptocurrency; One of the plurality of exchanges is selected, one of the plurality of cryptocurrencies is selected, and the quantity of the cryptocurrency is input according to the price information of the selected cryptocurrency of the selected exchange to purchase the cryptocurrency Or issuing a sell request; Paying cash or other cryptocurrency corresponding to the cryptocurrency bought or sold at the cryptocurrency exchange by the selected exchange; And transmitting, by the cryptocurrency exchange, the cryptocurrency corresponding to the paid cash or other cryptocurrency to the member's electronic wallet. It may include.

In the step of starting the price information of the plurality of cryptocurrencies of the plurality of exchanges on the cryptocurrency exchange through the linkage between the exchanges, a plurality of the plurality of cryptocurrency information of the plurality of exchanges, such as price, transaction volume, and quotation It may be a step in which an exchange is started and a highest price exchange at which the highest price of the cryptocurrency is started and a lowest price exchange at which the lowest price of the cryptocurrency is started are selected and started.

According to another aspect of the present invention, there is provided a computer-readable recording medium in which a program for executing any one of the above-described methods on a computer is recorded.

According to another aspect of the present invention, a computer program stored in a computer-readable recording medium for implementing any one of the above-described methods is provided.

About. Hereinafter, such devices and methods may be simply referred to as “cryptocurrency exchange system” and “cryptocurrency exchange operating method”.

Referring to Figure 1, in an embodiment of the method of operating a cryptocurrency exchange of the present invention, a cryptocurrency exchange system includes a blockchain network processing server 100, a cryptocurrency exchange server 200, a member terminal 300, a wired/wireless communication network. Includes (not shown).

When a block chain 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 adjacent nodes to confirm the blockchain transaction (transaction authentication and recording). ) Is completed, and the completion of the block chain transaction confirmation is notified to the cryptocurrency exchange server 200. For example, the block chain network processing server 100 may perform a block chain confirmation of completing a transaction by sending and receiving 6 confirmations with an adjacent node per block chain transaction. To this end, the blockchain network processing server 100 verifies 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 that authenticates currency transactions and records transaction information for cryptocurrency transactions with a blockchain is mounted according to the authentication. Therefore, peer-to-peer network (P2P: peer-to-peer network) that performs cryptocurrency transactions with a blockchain through verification and recording of confirmations for cryptocurrency transactions with the blockchain when transacting cryptocurrency with a blockchain. These are the devices that make up the underlying distributed blockchain network. In particular, in the present invention, in the configuration of such a block chain network processing server 100, an electronic wallet for each individual member operated by a cryptocurrency exchange corresponds to a member of one block chain network processing server 100.
