Description

Cryptocurrency trading system and method that equates the price with the base currency {Trading system and method of cryptocurrency}

The present invention relates to a cryptocurrency trading system and method, and more particularly, to a cryptocurrency trading system that promotes coin trading and equates a price with a standard currency that can be used as a stable currency and currency having an exchange function, and It's about how.

Recently, interest in bitcoin, a type of digital cryptocurrency that can be used for payment in kind, has been highlighted. Bitcoin is a digital currency created by Satoshi Nakamoto in 2009, and has a structure in which there is no central device that issues and manages the currency. Instead, Bitcoin transactions are performed by a distributed database based on a peer-to-peer network, and transactions are usually performed using a public key encryption algorithm.

In addition to Bitcoin, digital cryptocurrencies that can be used for payment in kind include Litecoin, Darkcoin, Namecoin, Dogecoin, and Ripple. Their common feature is that traders use digital cryptocurrencies including Bitcoin. The ledger of the transaction details of the transaction is stored in the electronic wallet, and the ledger is sequentially connected according to blockization and hash conversion in a certain unit, and can be shared on the blockchain network in a verifiable form by hash comparison. These cryptocurrencies can currently be exemplified by Bitcoin, Litecoin, Darkcoin, Namecoin, Dogecoin, and Ripple.

Individual blocks connected to such a blockchain may be sequentially connected according to hash conversion, and may be configured in the form of a data packet including a plurality of pieces of information. For example, the information included in the block may include transaction history in which participants traded currency, hash value of the previous block, difficulty level, nonce, and the like. Each block contains the hash value of the immediately preceding block, and blocks connected in this way can form a block chain that contains transfer details that occurred in chronological order.

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

In addition, the target of attacks such as hacking on the blockchain network should be the transaction system itself composed of a large number of unspecified nodes, not a specific terminal, and since the action itself destroys the transaction system itself, it is necessary to prepare for the cost of hacking. Hacking itself can be prevented in advance because of its low value of gain, and therefore reliable distributed transactions of cryptocurrency can be established without separate central control.

However, it is very difficult to lead to active use in the actual economy due to the instability of its value and the inconvenience of actual 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 the use is legally restricted at the national level. In particular, in order to solve the fundamental cause of value instability, the cryptocurrency formed by the blockchain network is secured by a specific legal currency or other cryptocurrency, resulting in a stable coin in the form of the same value as the legal currency ( STABLE COIN) method has also been proposed.

However, the collateral stabilization methods proposed so far require another currency as collateral, which results in the same volatility as the value volatility of the other currency. The problem is not yet resolved.

In addition, excessive stabilization lowers the profitability of holding or the need for currency transactions, reducing the number of holders, and thus reducing usability.

In other words, the fundamental problem of not achieving value creation through transactions and improvement of usability in real economic life together with the stabilization of the value of the cryptocurrency itself is still being raised.

The object of the present invention to solve the above-described problems is to promote coin transactions, and to use a stable currency that fluctuates at the same value as a standard currency such as the Korean won or dollar, and a standard currency and price that can be used as a currency having an exchange function. It is intended to provide a cryptocurrency trading system and method that equates to

A first feature of the present invention for solving the above problems is, in an online cryptocurrency trading system, a coin wallet for storing ownership information of a coin made of a cryptocurrency that fluctuates at the same value as a reference currency; a virtual coin exchange capable of moving the stored location of the coin to the coin wallet and trading the coin with the reference currency; And a base currency exchange unit for exchanging the virtual coin of the coin wallet and the virtual coin exchange with the base currency, wherein the base currency exchange unit enables exchange of the coin in the coin wallet with the base currency, and the base currency exchange When trading is matched based on the purchase amount according to the purchase and sale orders of virtual coins in the virtual coin exchange with a negative base currency, the total quantity of the virtual coins held in the virtual coin exchange is the trading execution matching ratio It may be that it fluctuates.

Here, the trade execution matching ratio is preferably a value (B/S) obtained by dividing the purchase quantity (B) by the sale quantity (S) at the time of trade execution, which is set at a certain round cycle, and the total of the virtual coins fluctuating The quantity is preferably calculated by multiplying the total quantity prior to the trade execution time by the trade execution matching ratio (B/S).

In addition, the virtual coin exchange may include a trading input unit for specifying the quantity of the virtual coin and inputting an order for buying and selling; a virtual coin variation unit for calculating the trading execution matching ratio and changing the total quantity of the virtual coins located in the coin exchange when the trading execution is matched according to the buying and selling orders of the trading input unit; a trade settlement settlement unit that settles trades based on the number of purchases and sales of virtual coins changed by the virtual coin change unit; and a virtual coin storage unit configured to store virtual coins that are increased or decreased according to settlement results of the virtual coin variable unit and the transaction settlement settlement unit.

And, the second feature of the present invention is a cryptocurrency trading method that equates the price with the base currency, (a) purchasing a virtual coin through the trading input unit in the virtual coin exchange using the base currency of the base currency exchange unit or placing a sell order; (b) calculating the trading execution matching ratio when the trading execution matching is achieved according to the buy or sell order by the virtual coin exchange; (c) varying the total quantity of the virtual coins located in the coin exchange according to the calculated trading execution matching ratio and settling the trading execution by the virtual coin exchange; and (d) storing the virtual coins according to the quantity of the virtual coins changed by the virtual coin storage unit.

Here, the virtual coin of the virtual coin exchange and the coin of the coin wallet can be moved according to the user's selection with the same value, but the coin of the coin wallet may not affect the increase or decrease of the virtual coin exchange. there is.

The effects of the present invention to solve the above problems are as follows.

First, the present invention provides a cryptocurrency trading system and method capable of activating the trading market and stably performing exchange and currency functions.

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

1 is a diagram showing the block configuration of a cryptocurrency trading system that equates a price with a base currency according to an embodiment of the present invention.

As shown in FIG. 1, the cryptocurrency trading system according to an embodiment of the present invention, in the online cryptocurrency trading system, is a coin wallet ( 100); a virtual coin exchange 200 capable of moving the stored location of the coin to the coin wallet and trading the coin with the reference currency; And a base currency exchange unit 300 that exchanges the coin of the coin wallet and the coin exchange with the base currency, wherein the base currency exchange unit enables coin trading between the coin wallets in the base currency, and the base currency When the trading is matched based on the purchase amount according to the buying and selling order of the coin in the virtual coin exchange as the base currency of the exchange unit, the total quantity of the coin held in the coin exchange is increased or decreased by the trading match matching ratio it may be Here, coin means a cryptocurrency applied to an embodiment of the present invention.

As such, the embodiment of the present invention applies a method in which the price per coin fluctuates according to the demand, supply, buy and sell signal of the cryptocurrency, as in the stock market, in the system for trading cryptocurrency in the conventional cryptocurrency exchange, in a short time Due to the large volatility within the currency, it was difficult to exchange at the same price as the existing legal currency, and there was a problem that the effectiveness as a currency value was reduced.

Therefore, in the embodiment of the present invention, in order to stably perform the function as a monetary value and exchange value while increasing the activation of the cryptocurrency trading market, the change in the value of the cryptocurrency is replaced with a change in quantity in the virtual coin exchange 200. It is implemented so that it can be traded, and is independently provided with a storage called a coin wallet 100 that fluctuates at the same value as the standard currency or legal currency, and the virtual coin of the virtual coin exchange 200 and the coin of the coin wallet 100 are As the same value, it provides a cryptocurrency trading system and method that can activate the trading market and stably perform exchange and currency functions by allowing the location of coins to be freely moved to each other.

Here, as shown in FIG. 1, the cryptocurrency trading system according to an embodiment of the present invention includes a coin wallet 100 that stores ownership information of coins having the same value as the base currency, and buy and sell orders for virtual coins. A virtual coin exchange 200 and coin wallet 100 that can exchange price fluctuations of virtual coins with quantity fluctuations and a base currency exchange unit 300 capable of exchanging base currency with the virtual coin exchange 200 can be configured including

Here, transaction users using the cryptocurrency transaction system illustrated in FIG. 1 may be multiple users, and all users of coins applied to the embodiment of the present invention are exemplified.

In addition, it is a software that tracks a secret key used to digitally sign a cryptocurrency transaction with a cryptocurrency wallet of the coin wallet 100 and the virtual coin storage unit 240, and the secret key proves ownership of digital assets and protects assets. It is the only means of executing a transfer or change transaction.

The coin wallet 100 may be of two types: hardware and software, but in the embodiment of the present invention, it is software implemented online and can be accessed through Internet services, and can also be a client wallet managed by a computer or mobile device. do.

As such, in the embodiment of the present invention, as software for estimating a secret key for storing or proving ownership information of a coin, it can be applied as a web or app that can perform functions on a computer or mobile device as a client online, where stored The coin having ownership information is stably changed to the same value as the base currency without being affected by the quantity change of the virtual coin exchange 200. Here, the base currency may be a legal currency such as a legal currency or a cryptocurrency that is commonly used in a general market such as won or dollar. That is, if the coin is changed to the same value as the standard currency, it can stably function as a currency and exchange value, and can also be exchanged with general legal currency, goods, and services.

In addition, as shown in FIG. 1, since the coin stored in the coin wallet is changed to the same value as the standard currency, it can function as a currency that can be exchanged with the real thing, such as general goods, through the real exchange unit 500. Coins can be exchanged for the value of the real thing and the base currency.

That is, goods or services such as bread, coffee, shoes, food, etc., which are routinely purchased at general stores, can be purchased or serviced by paying with coins held in the coin wallet through the physical exchange unit 100.

In addition, since the value of the coin in the coin wallet 100 is the same as that of a general legal currency account, it has the advantage of being able to function and use it as one asset value such as interest, rental, or collateral.

The virtual coin exchange 200 applied to the cryptocurrency trading system according to an embodiment of the present invention is an exchange in which the quantity fluctuates, not the price change of virtual coins according to the purchase and sale of virtual coins, and the virtual coin exchange is based on the base currency. While trading, the trade execution according to the buy and sell orders is matched based on the purchase amount, and the total quantity of virtual coins existing in the virtual coin exchange 200 is determined according to the matching ratio of the buy and sell amounts of virtual coins according to the matched execution. It refers to a system that changes and settles trades.

Here, the trade execution matching ratio refers to the ratio or multiplication of the purchase order quantity to the sell order quantity in order to complete the trade execution by making the buy and sell order quantities the same when there is a difference in the quantity of the buy and sell orders.

More specifically, the trade execution matching ratio may be a multiplier (B/S) of the quantity bought (B) to the quantity sold (S) of the virtual coin at the time of trade execution, which is set at a certain round cycle, and fluctuates The total quantity of virtual coins may be calculated by multiplying the multiplier (B/S) by the total quantity before the trade conclusion.

Here, setting the trading execution to a preset cycle cycle means that when continuous trading is concluded in real time, the fluctuation range of the virtual coin quantity of the virtual coin exchange 200 approaches infinity, which may cause transaction distortion, and the contract matching This is because the calculation load for calculating the ratio and settlement becomes excessive, which negatively affects its function as money.

That is, the virtual coin exchange 200 applied to the embodiment of the present invention executes and matches buy and sell orders, and increases or decreases the total quantity of virtual coins held in the virtual coin exchange 200 according to the match matching ratio. , It is not a conventional coin whose price fluctuates unstablely, but the price is fixed at the price of the standard currency and only the quantity fluctuates, so it has the advantage that it can be exchanged with the standard currency at any time.

More specifically, the virtual coin exchange 200 calculates the trading execution matching ratio according to the buying and selling orders with the trading input unit 210 for buying and selling orders of users, and the virtual coin according to the trading execution matching ratio. A virtual coin variable unit 220 that increases or decreases the quantity of all virtual coins held in the exchange 200, and a trade settlement settlement unit 230 that settles trades according to the sold quantity and purchased quantity of virtual coins whose quantity has changed and a virtual coin storage unit 240 in which settled virtual coins are stored.

Here, the virtual coin is a cryptocurrency having the same value as the coin existing in the coin wallet 100, and a virtual coin whose quantity fluctuates according to the conclusion of a trade is assumed, and the virtual coin storage unit 240 It may be a coin wallet inside the virtual coin exchange 200 that stores ownership information of the changing virtual coin.

In addition, the virtual coins stored in the virtual coin storage unit 240 can be freely moved to the coin wallet 100, and since their values are the same as the base currency, they can be exchanged for the base currency or converted into cash through a sell order.

And, as shown in FIG. 1, the base currency exchange unit 300 means a system that is connected to the coin wallet 100 and the virtual coin exchange 200 online and exchanges coins for the base currency. In the exchange 200, after trading and settlement according to the purchase and sale orders of virtual coins, the settlement can be made in the base currency. It performs the function of a conventional cryptocurrency virtual account system.

In addition, the virtual coin stored in the virtual coin storage unit 240 cannot be directly exchanged for the virtual coin into the base currency through the base currency exchange unit, but can be exchanged for the base currency through a sell order of the trading input unit 210. However, this is because the quantity of virtual coins stored in the virtual coin storage unit 240 can change greatly from time to time due to the transaction of virtual coins, and by using this, the virtual coins are intentionally exchanged for the base currency and converted into cash. Because it can cause distortion.

In this way, by providing a base currency exchange unit capable of realizing monetization through coin trading, it is possible to motivate virtual coin trading and promote coin trading by stably reflecting market demand for buying and selling.

In addition, as shown in FIG. 1, the excavation unit 400 means a system capable of excavating cryptocurrency, and the user moves or inserts the mined coin into the coin wallet 100 using a general cryptocurrency excavation system. In addition, it can be imported or moved to the virtual coin storage unit 240 of the virtual coin exchange 200.

Here, the quantity of the coin wallet 100 excavated and introduced through the excavation unit 400 does not change, and the coin introduced into the coin storage unit 240 fluctuates in the total quantity of coins, so the virtual coin exchange ( 200), and is affected by the matching ratio of purchase and sell orders.

In addition, the total amount that can be issued can be fixed for the cryptocurrency applied to the embodiment of the present invention, and it is also possible to limit a certain amount of issuance and allow mining within that range.

As such, the cryptocurrency trading system according to an embodiment of the present invention is provided with a coin wallet 100 that is stored at the same value or price as the standard currency to implement stable currency and exchange value functions of the coin, buy and sell Depending on the order, the change in the value of the virtual coin is replaced with the change in quantity through the matching of the trade agreement, thereby providing stable coin exchange activation at the same time.

2 is another embodiment of the present invention, a diagram showing the flow of a cryptocurrency transaction method that equates a price with a base currency.

As shown in Figure 2, the cryptocurrency trading method according to an embodiment of the present invention, (a) the virtual coin exchange 200 through the trading input unit 210 using the standard currency of the standard currency exchange unit placing an order to buy or sell coins (S100); (b) calculating the trading execution matching ratio when the virtual coin exchange 200 is matched according to the purchase or sale order of the virtual coin (S200); (c) the virtual coin exchange 200 changing the total quantity of the virtual coins located in the virtual coin exchange 200 according to the calculated trading execution matching ratio and settling the transaction (S300); (d) storing the virtual coins according to the number of virtual coins changed by the virtual coin exchange 200 (S400).

As shown in FIGS. 1 and 2 in more detail, first, the user places an order to buy and sell virtual coins in the virtual coin exchange 200 through the trading input unit 210 (S100). Here, the order to sell or buy A sale or purchase order is placed in the base currency exchange unit through the trading input unit 210 in the base currency.

Then, the virtual coin fluctuation unit 220 determines the matching quantity that can be traded according to the buy and sell orders, calculates the match matching ratio, and the virtual coin exchange 200 excluding the coin wallet according to the ratio The total number of virtual coins is changed (S200), and the trade settlement unit 230 settles trades according to the changed quantity of virtual coins (S300). It can be settled in the standard currency according to the number of purchases and sales of virtual coins. That is, the base currency corresponding to the purchase quantity of virtual coins of the buyer is transferred to the seller's base currency virtual account for settlement, and the virtual coin storage unit 240 of the buyer stores virtual coins corresponding to the number of purchases (S400). Coin trading may be activated by repeating the same virtual coin trading steps (S100 to S400) according to preset cycles.

3 is a diagram showing the flow of a transaction process with a buying advantage as one embodiment of a cryptocurrency transaction method that equates the base currency and price according to the present invention, and FIG. 4 shows the flow of the base currency and price according to the present invention. As one embodiment of the equating cryptocurrency trading method, it is a diagram showing the flow of a trading process with a selling advantage.

In the coin transaction process shown in FIG. 3, the total amount of coins issued is 200, and the user A holds 100 virtual coins in the virtual coin storage unit 240 of the virtual coin exchange 200 and 100 coins in the coin wallet. A user named B, who has a dog, exemplifies a coin transaction process performed while having 0 coins in the virtual coin exchange 200 and coin wallet.

First, A places a sale order for 30 coins in the coin wallet through the currency exchange unit, and sells 20 virtual coins through the trading input unit of the virtual coin exchange 200. In addition, B places a purchase order for 100 coins through the currency exchange unit, and the 30 coins are traded with A's 30 coin sell order through the coin wallet, and the remaining 70 coins are traded in the virtual coin exchange 200. A buy order is placed through (210).

That is, the example of FIG. 3 exemplifies a process of concluding a trade with a buying advantage in a virtual coin exchange.

In order for the virtual coin variable unit 220 of the virtual coin exchange 200 to match the purchase amount (70) and the sale amount (20) to match, first, the total amount of virtual coins sold in the virtual coin exchange 200 is Since the current number of 20 does not satisfy the purchase amount of 70 of B, the total number of virtual coins of the virtual coin exchange 200 is increased by 3.5 times.

The virtual coin variation unit 220 calculates a matching ratio to match B's selling amount of 20 virtual coins and A's buying amount of 70 in a state where 70 of the possible trading quantities are set. Here, the trade execution matching ratio means the value (B/S) divided by the number of purchases (B: Buy) of virtual coins (S: Sell), and the number of purchases of B is 70, the number of sales of A is 20. Means a factor of 3.5 divided by

Here, the multiplier of 3.5 is the total number of virtual coins currently held by the virtual coin exchange (200) in order to match the execution by matching the small selling quantity (20) to the buying quantity (70) in the buying and selling process with a buying advantage. Corresponds to the magnification to be adjusted. Therefore, the virtual coin changer 220 changes the transaction execution matching ratio of 3.5 times to 350, which is 3.5 times the total number of 100 virtual coins of the virtual coin exchange excluding the number of coins in the coin wallet before the transaction. In other words, the total number of virtual coin exchanges is increased to 350, and the number of trades is matched to 70.

Then, since the transaction settlement settlement unit 230 settles the transaction based on the number of all virtual coins that have been changed by the virtual coin exchange 200, B exchanges 70 virtual coins as standard through the currency exchange unit. The purchase amount deposited in currency is paid and 70 virtual coins are secured, A sells the 70 virtual coins, and the 70 virtual coins are transferred to and stored in B's virtual coin storage, and the 70 virtual coins paid by B are stored. Secure the coin purchase price.

Therefore, as shown in FIG. 3, after a certain round of trade settlement, looking at the number of coins held in the coin wallets of A and B and the virtual coin exchange 200 and the result of the settlement of the trading price, in the coin wallet 100 A sells 30 of the 100 coins, and 70 coins remain, and B buys and holds 30 coins in the coin wallet.

In addition, in the virtual coin exchange 200, B buys 30 coins from the total 100 coin purchases through the coin wallet 100, and buys the remaining 70 coins. Since the total quantity of virtual coins in the exchange 200 is increased from 100 to 350, the matching quantity of trading is 70, so A transfers 70 virtual coins to B, and B transfers the currency exchange unit 300 Through , 70 virtual coins are paid to A in the standard currency, and the transaction is finally settled. That is, in the virtual coin exchange, after settlement of trades, A holds 280 virtual coins and B holds 70 virtual coins.

In this way, when the cryptocurrency trading method according to the embodiment of the present invention is applied, the rapid price change or value change through trading in the coin exchange is replaced with the change in the quantity of coins to activate the transaction, and if necessary, the virtual coin exchange (200 ) to the coin wallet 100, which is not affected by fluctuations in the number of virtual coins, and provides a transaction method that can stably function as currency or exchange value.

And, FIG. 4 illustrates a trading process to which the cryptocurrency trading method according to an embodiment of the present invention is applied as an example of a selling advantage, and illustrates a trading process extended from the example of FIG. 3 .

The total number of virtual coins of the virtual coin exchange 200 is increased to 350 in the example of FIG. 3, A has 280 virtual coins in the virtual coin storage 240 corresponding to the internal account, and B has 70 I have a virtual coin. And, since the coin wallet 100 is not affected by the quantity change of the virtual coin exchange 200, A still holds 70 coins and B still holds 30 coins, as in the example of FIG.

First, through the trading input unit 210 of the virtual coin exchange 200, B places an order to buy 50 virtual coins, and A places an order to sell 100 virtual coins. The virtual coin variable unit 220 first determines the traded quantity in order to calculate the traded match ratio. Since it is centered on the purchase order, it determines the traded traded quantity with 50 virtual coins within the range of the total coin quantity. Then, in order to match the trading volume of 50 units, a trading execution matching ratio, which is a value (0.5) divided by the number of purchases (50 units) by the number of units sold (100 units), is calculated.

The total number of virtual coins in the virtual coin exchange 200 (350) is multiplied by 0.5, the matching ratio of the virtual coin variable part 220 and the virtual coin variable part 220 of the virtual coin exchange 200, so that the total number of virtual coins is 350. It changes from (A: 280, B: 70) to 175 (A: 140, B: 35). And, A holds 140, which is half of 280, and B holds 35, which is half of 70. Since the matching quantity for trading is 50, A sells 50 of 140 virtual coins and concludes trading After that, B will have 90 remaining virtual coins, and B will have a total of 85 remaining virtual coins by purchasing 50 of 35 virtual coins. Then, the purchase price of 50 virtual coins is paid by buyer B through the currency exchange unit 300, and A secures the purchase price.

Here, selling in the coin wallet 100 is performed through the base currency exchange unit 300 by moving coins from the coin wallet 100 to the virtual coin storage unit, or directly to the coin wallet 100 by the base currency exchange unit 300 Since a problem may occur when the amount of purchase is less than the sale, the sale transaction from the coin wallet 100 to the standard currency exchange unit 300 is closed as necessary, and the virtual coin is sold in the coin wallet 100. It may be realized that selling is possible by switching to selling through the storage unit 240 and the base currency exchange unit 300.

As such, the cryptocurrency trading method according to the embodiment of the present invention illustrated in FIGS. 3 and 4 replaces the trading of the virtual coin exchange 200 with a change in quantity through trade execution matching, thereby activating coin trading. and, if necessary, by allowing virtual coins to be moved to the coin wallet 100 that does not affect the quantity change of the virtual coin exchange 200, the cryptocurrency can be exchanged at the same value or price as legal tender such as won or dollar. It provides a cryptocurrency trading method with a stable currency and exchange function that fluctuates.
