Description

COMPUTING SYSTEM ENABLES INVESTMENT THROUGH BIDIRECTIONAL DEPOSIT OF COLLATERAL AND CONTROL METHOD THEREOF

The present invention relates to a system for making a loan using collateral as collateral, and more particularly, depositing collateral in an investment form that generates a profit when the value of collateral increases and/or decreases, and a loan corresponding to the deposited collateral It relates to a system that implements and a method for controlling the same.

As an online payment method, the importance of cryptocurrencies such as Bitcoin (BTC) and Ethereum (ETH) is steadily increasing. Online payment (or payment) is rapidly increasing in use with the generalization of the Internet and smartphones and the advent of simple payment. This is because cryptocurrency has very good advantages that traditional payment methods do not have, such as not only being able to use borderless, but also allowing parties to trade instantly without a middleman. Therefore, blockchain technology can bring the world together by providing people around the world with easy financial services such as online transfers and instant payments.

However, one of the biggest obstacles encountered in using cryptocurrency in real life is that price volatility is very large. This makes it very difficult to use cryptocurrency as a medium of exchange and store of value. This is because such severe price volatility is highly likely to give an economic disadvantage to one party to the contract. For this reason, stablecoins, which peg prices to the US dollar as a legal currency or gold as a commodity, are sometimes considered as the holy grail of crypto. Since these stablecoins have a fixed price, they can be easily used to purchase services or goods, and have the advantage of being used as a hedge against market volatility. In other words, these are cryptocurrencies with the purpose of maximizing usability by stabilizing the price, and several types of stablecoins that have already implemented the price fixing function are already being traded in the market. Specifically, they can be classified into fiat-collateralized, non-collateralized, and crypto-collateralized according to the type of collateral.

The existing secured loan is a method in which the borrower deposits collateral (or underlying assets) whose price fluctuates with respect to the loan amount to the collateral loan operator, bundles them, and pays the loan amount. Therefore, the basic principle of this is to freeze the collateral as a kind of security deposit and return it to the borrower after the contract is terminated. Therefore, typical existing collateral is characterized by being limited to assets traded in the spot market, such as stocks and real estate.

Existing cryptocurrency collateral loans have the same principle as existing general collateral loans, but only use cryptocurrency as collateral. It can be classified into two types. The first is to pay the loan in another cryptocurrency that already exists, such as compound (https://compound.finance), which is the same loan method as the existing secured loan. For example, this is a method in which the borrower deposits Bitcoin as collateral and pays the loan in Tether, which is already in circulation. The second, like MakerDao (https://makerdao.com), is a method of issuing and paying a new stablecoin, DAI, as a loan. It is a new loan method completely different from the existing secured loan, which MakerDao provided for the first time. This method has the advantage of being able to obtain various new business opportunities using the stablecoin, since the operator uses the stablecoin issued by the operator as a loan.

1 shows the loan process of DAI, which is an existing cryptocurrency secured loan. It consists of a borrower who provides Ethereum (ETH) as collateral, and a Collateralized Debt Position (CDP), an operating program that receives collateral and pays the borrower DAI, a stablecoin, as the loan amount. In addition to these, there are more clearing houses for forced liquidation, but the basic loan structure of DAI is shown in Figure 1. This is a method in which the borrower provides Ethereum (ETH) as collateral to the CDP, the CDP binds it to the network, and the corresponding loan is issued by a new stablecoin, DAI, and paid. Therefore, DAI classifies it as a crypto-collateralized stablecoin.

The biggest feature of these secured loans is that in order to maintain the value of DAI, the borrower provides the loan after freezing the collateral in the CDP. What this means is that in conventional secured loans, the loan, like all existing secured loans, is at the disposal of the operator and its value is guaranteed by collateral that is locked with excess collateral. Here, CDP is a smart contract of Ethereum, an automation program that operates on a cryptocurrency network.

In other words, in order to maintain the value of DAI, these crypto-secured loans provide DAI as a loan through a deposit (or lock-up) function that binds collateral to the CDP. This deposit function is essential because it is the last means for the operator to collect the loan by forcibly disposing of the collateral. For this reason, all secured loans must include automatic liquidation to forcibly collect the loan if the value of the collateral decreases. In the case of DAI, the liquidation money recovered from forced liquidation is deposited in the network and continues to be used as collateral for the corresponding DAI. In other words, the forcibly liquidated DAI is not incinerated and continues to circulate in the market. Besides this, there is a normal 'liquidation' by the borrower. This is how the borrower returns all of the loan and ends the loan gracefully. In the case of DAI, all DAI returned in this way is incinerated. Because of this, all other DAI in circulation is always held in value by over-collateralized collateral.

However, in the event of forced liquidation, the borrower will not be able to gain any profit from the re-increase in the price of the collateral in the future, as well as the loss caused by the falling price of the collateral. For this reason, in all secured loans, the higher the price volatility of the collateral, the higher the over-collateralization is required from the borrower. For this reason, the collateral of all secured loans has no choice but to prefer the less volatile assets. This is because, with the same excess collateral, the higher the price volatility of the collateral, the higher the risk of forced liquidation. As a result, in all secured loans, the collateral has no choice but to prefer assets with low price volatility.

However, the historical volatility of cryptocurrency prices is much greater than that of traditional collateral such as real estate or stocks. For example, according to the coinmarketcap.com site, the price of Bitcoin (BTC) rose from $ 1,883 on July 17, 2017 to $ 19,896 on December 17, 2017, about 5 months later, about 10.5 times higher. And about 10 months later, on October 16, 2018, it dropped about 84% to $3,228. Not only that, but about 8 months later, on June 27, 2019, it again rose 4.2 times to $13,725. As such, the historical volatility of cryptocurrency prices is much higher than that of stocks or real estate, which are collateral for existing secured loans. In other words, cryptocurrencies as collateral have a much higher risk of being forced into liquidation than conventional collateral, which raises the problem of requiring more excess collateral. As a result, the average loan-to-value ratio (LTV) of existing cryptocurrency-backed loans is about 30%, which is very low compared to existing collateral. 1 is an example of paying DAI of $30 as a loan when a borrower provides $100 of Ethereum as collateral. So its LTV is 30%. For reference, the loan amount in a secured loan is calculated by multiplying the value of the collateral at the time of the loan by the LTV.

In all secured loans currently providing services, including cryptocurrency secured loans, the operator operates with the concept of storing the collateral entrusted by the borrower. In other words, in the existing secured loan, the operator temporarily stores the collateral, which is the borrower's asset, while the position of the collateral entrusted by the borrower is maintained, and then returns it to the borrower when liquidated. Exceptionally, the concept of storage means that when the value of collateral falls, additional collateral is requested or the loan is recovered by forcibly liquidating it.

However, in all existing secured loans, the collateral causes a fatal problem in that the value of the collateral increases only when the price rises. This means that in conventional secured loans, the borrower always takes out the loan with a bet on the price of the collateral to rise. Therefore, the value of the collateral of the existing secured loan increases only when the price rises, that is, only when it moves in one direction. Let's call this 'one-way deposit method of collateral'. In other words, in the existing secured loan, all collateral has a one-way profit structure that bets on upside profit.

Existing cryptocurrency collateral loans such as DAI use the same one-way deposit method in which CDPs simply store Ethereum. In conclusion, in all existing secured loans, the collateral always uses the one-way deposit method. However, due to this, all existing secured loans have serious disadvantages that limit borrowers' options.

Therefore, there is a need for research on a computing system that can bet on a falling profit as well as a rising profit of the collateral.

SUMMARY OF THE INVENTION The present invention aims to solve the above and other problems. Another object is to provide a secured loan system that enables two-way deposit of collateral according to the borrower's choice.

2 shows a block diagram of a computing system 12 capable of investing through two-way deposit of collateral according to the present invention, a terminal connected to the computing system, and an exchange computing device.

The present invention may include a borrower terminal 11, an exchange computing device 15 (hereinafter referred to as an exchange) and a computing system 12, all of which are a cryptocurrency network 13 and/or a general network 13 ) to transmit and receive data.

Computing system 12 according to an embodiment of the present invention, the communication unit 12c for connecting to the network 13 for transmitting and receiving data with the borrower terminal 11 and the exchange 15, data related to the loan It may include a storage unit (12b) for storing, and a processing unit (12a) for processing a loan payment in response to a loan request received from the borrower terminal. The processing unit 12a may control the overall operation of the computing system 12 .

The processing unit 12a processes to receive the collateral from the borrower terminal 11 . In this case, the computing system 12 may directly receive the collateral, or a third party (or a computing system of an exchange operated by a third party) may receive the collateral. That is, some or all of the collateral can be stored by the processing unit 12a, and some or all of the collateral can be transferred to the exchange 15 and the condition set by the processing unit, that is, the borrower terminal 11 set You may be provided to directly invest in investment products under the condition of the two-way deposit ratio.

The computing system 12 according to an embodiment of the present invention may be configured with a blockchain technology that issues and operates cryptocurrency. In other words, in the case of blockchain technology, a large number of decentralized nodes add and store transaction data in the blockchain, which is the ledger. In addition, in the case of the exchange, a decentralized exchange operated in a block chain may be used, or a centralized exchange, that is, an exchange operated as a server may be used. In contrast, in the case of the legal currency-based secured loan system according to the present invention, the computing system 12 and the exchange according to an embodiment of the present invention may be configured as a server.

The processing unit 12a may process some or all of the provided collateral to be invested as a down-deposit, and the remainder of the collateral may be processed to be invested as an up-dated deposit. The investment as the downward deposit and the upward deposit means a type of investment in which a profit is generated when the price of the collateral falls and rises, respectively.

In particular, in one embodiment of the present invention, it is proposed that the bidirectional deposit ratio, which is the ratio of the falling deposit and the rising deposit, is set by the borrower terminal.

Hereinafter, the rising deposit and the falling deposit will be described in more detail.

The bidirectional depositing method of collateral according to an embodiment of the present invention proposes a collateral loan method in which an operator invests in an investment product in which the value of collateral increases when the price of collateral rises or falls according to a ratio selected by a borrower. In other words, the loan system according to an embodiment of the present invention invests a corresponding collateral in a two-way investment product according to a ratio selected by a borrower, and is a new collateral management system in which an investment concept is newly added to the operation of collateral. In the detailed description of the present invention, investing so that the value of the collateral increases when the price rises is called 'upward deposit', and on the contrary, investing so that the value increases when the price of the collateral falls is called 'downward deposit'.

For example, in one embodiment of the present invention, you can use a cryptocurrency exchange that provides arbitrary products such as margin trading and derivatives trading so that you can make a profit from 'rising deposit' and 'downward deposit' of collateral prices. Of course, the upward deposit and the downward deposit refer to any investment or investment product having any form and arbitrary investment structure in which the value of the corresponding collateral increases with respect to the increase and decrease in the price of the collateral, respectively. Accordingly, the two-way deposit may mean any product that can be invested in both directions. In general, when using a derivative product, the up-and-down deposit is a method of investing collateral in long and short positions, respectively. say that

Table 1 below is an example showing the change in the value of collateral when the price of Bitcoin (or the price of the underlying asset) changes by ±50% after the borrower deposits 1 BTC of Bitcoin as collateral in both directions. In the table, the upward and downward deposits assume an ideal situation where you invest in products denominated in BTC and inverse BTC, respectively, and there are no transaction fees. It is also assumed that the price of the underlying asset and these two products at the time of loan is $10,000, and the price of the underlying asset rises ±50% after lending, so that the price of the underlying asset is $15,000 and $5,000, respectively, to liquidate the loan. And it is assumed that these two products accurately follow in both directions at a ratio of 1x the price of the underlying asset without leverage. Here, the two-way deposit ratio refers to the ratio of the rising deposit and the falling deposit selected by the borrower at the time of lending, and for example, the (two-way) deposit ratio of 90:10 in the table is 90% and 10% for the rising and falling deposits, respectively. means the case. And in the example of Table 1, the underlying asset is the spot Bitcoin.

Table 1 shows the LTV and profit/loss ratio according to ±50% change in the price of the underlying asset at the ratio of various two-way deposits of collateral (collateral: 1 BTC, the underlying asset at the time of loan, BTC product price and inverse BTC product price: $10,000).

In Table 1 above, the (both directions) deposit ratios of '100:0' and '0:100' are cases in which the collateral is fully invested in the upward deposit and the downward deposit, respectively. And the deposit ratio of '70:30' is when the collateral is invested in the up and down deposits at 70% and 30%, respectively. In this case, if the underlying asset, the Bitcoin spot, is liquidated when the price rises by 50%, the borrower will receive 0.8 BTC back as shown in Table 1 and lose 0.2 BTC, but the return in dollars is 20%. And since the LTV of the loan is 57%, it is higher than the LTV of 30% when all collateral is invested in a rising deposit. Here, this LTV (30%) is the average value of a cryptocurrency secured loan, and this is just one example.

Hereinafter, a method for determining the loan amount will be described in detail.

The loan amount is calculated by multiplying the value of the collateral at the time of the loan by the LTV. In the system of the present invention including a two-way deposit method, the LTV of the loan can be divided into two parts. In other words, there are parts that do not change the value of collateral and loans with time after the loan and parts that change.

In the present invention, the part whose value fluctuates according to the price change of the collateral after the loan is defined as the 'value change part', and the part where the value of the loan does not change even if the price of the collateral changes and the fixed part is the 'value 'fixed part'. The loan money according to an embodiment of the present invention may be made to include at least one of a value-variable part whose value fluctuates with respect to a price change of the collateral and a value-fixed part whose value does not change. For reference, all existing secured loans are part of the change in value.

In particular, in one embodiment of the present invention, it is proposed to set different LTVs for the fixed value portion and the variable value portion of the loan. That is, the security recognition ratio (LTV) of the fixed value portion may be set higher than the security recognition ratio of the value change portion. In this embodiment, as shown in Table 1, the amount of the loan may be determined by individually reflecting the collateral recognition ratio of the value change part and the value fixed part.

This is because, in the value-variable part, a high LTV cannot be recognized because the value literally changes with time after lending, but a high LTV can be recognized because the value of the fixed value part does not change at all. . That is, the amount of the loan may be determined by setting the security recognition ratio of the value fixed portion to 100% or less so that forced liquidation does not occur due to lack of collateral for the value fixed portion.

For example, in Table 1, the LTVs for the fixed value part and the variable value part of the loan were set at 95% and 30%, respectively. For this reason, in the case of '50:50' and the (two-way deposit) deposit ratio of '100:0' in the table, the LTV becomes 95% and 30%, respectively. As shown in Table 1, in the case of the deposit ratio of '30:70' for collateral, 30% of each of the up and down deposits, and therefore the total of 60%, are completely hedged in opposite directions, so the loan amount and The collateral maintains the same value as at the time of the loan regardless of changes in the price of the underlying asset after the loan. However, the value of the loan and collateral of the remaining 40% of the change in value changes according to the change in the price of the underlying asset. In this case, the variable value and the fixed value of the collateral during the loan are $4,000 and $6,000, respectively, as shown in the table. Table 1 shows the variable value and the fixed value of collateral and loans.

The reason for dividing the loan into two parts in the present invention is that the risk of loss of these two parts is completely different with respect to the price change of the underlying asset after the loan. For this reason, in the table, the collateral recognition ratio of the fixed value part of the loan was set at 95%, but the LTV of the value change part in the deposit ratios of both extremes (100:0, 0:100) was set at 30%. As such, there is a big difference in the LTV of these two parts of the loan. For this reason, in a 50:50 deposit ratio, since every part of the loan is the fixed value part ($10,000), the loan amount is calculated by multiplying this part by the LTV (95%) at the time of the loan. Therefore, the LTV becomes 95% as shown in the table. As another example, in both extremes of the deposit ratio (100:0, 0:100), the loan is a value change part ($10,000), so the loan is calculated by multiplying this part by the LTV (30%). So at a deposit ratio of 100:0, the LTV is 30%. In other cases, the loan in the table may contain only the fixed-value portion or both. For example, at a deposit ratio of 90:10, the loan includes both a variable-value portion ($1,333) and a fixed-value portion ($1,900). Here, the loan amount of the fixed value part is calculated by multiplying the fixed value part ($2,000) of the collateral by the LTV (95%). And as shown in Table 2 below, the loan amount of the variable value part ($1,333) is calculated based on the liquidation price. In the value change part ($8,000) of the collateral, if the underlying asset falls to the liquidation price, it is liquidated in the value change part ($8,000) We subtracted $6,400 and divided the liquidation rate by this to determine $1,333. Therefore, in this case, the LTV of the secured loan is 32.3%. In contrast, at a deposit ratio of 70:30, the loan includes only the fixed value portion, and this portion of the collateral ($6,000) is multiplied by the LTV (95%) to get $5,700.

The processing unit 12a of the computing system 12 according to an embodiment of the present invention, when the value of the value change portion of the loan is expected to be insufficient due to the increase or decrease in the collateral value of the collateral, compulsory liquidation for this portion will be able to handle

In another embodiment of the present invention, the computing system 12 maintains a constant value of the fixed value portion of the loan when the price of the collateral changes so that forced liquidation does not occur in the fixed value portion due to the price change of the collateral. It may be set to automatically change the ratio of the up-deposit and the down-deposit corresponding to the value fixed portion so as to be maintained. That is, the ratio of collateral in the two deposits can be changed so that forced liquidation does not occur due to insufficient value of one of the rising and falling deposits among the fixed values.

Or, in another embodiment of the present invention, including only the fixed value portion may determine the amount of the loan. That is, it can be set not to include the loan amount for the value change part in a specific two-way deposit ratio. According to this embodiment, there is an advantage that there is no forced liquidation due to lack of value of collateral.

The characteristics of the bidirectional deposit method shown in Table 1 are summarized below.

Even if the price of collateral falls, borrowers can benefit from a higher drop-out ratio. This is a new deposit method according to the present invention that is not in the existing secured loans.

Lenders can adjust the bidirectional deposit ratio to include a fixed portion of value not found in traditional mortgages. Since this portion of the loan does not fluctuate in value, it can provide a very high LTV.

The higher the percentage of the fixed value part, the higher the LTV will be, so the loan will increase accordingly. Due to this, the closer the two-way deposit ratio approaches 50%, the smaller the difference in the profit/loss ratio of dollars depending on the betting direction.

The higher the drop deposit ratio, the greater the difference in Bitcoin's profit/loss ratio according to the betting direction of the collateral.

The two-way deposit method according to an embodiment of the present invention may invest in any product such as margin trading or derivatives or cryptocurrency ETFs or securities or funds in an exchange in order to invest in collateral in both directions. And the exchange according to the present invention may be an exchange that trades cryptocurrencies or fiat-based assets. If the loan is cryptocurrency, the operator can use a centralized exchange at the beginning of the business, but if conditions are met, it will use a decentralized exchange (DEX). Therefore, as an embodiment of the present invention, an investment in an investment product for depositing the amount of collateral can be made using a decentralized exchange (DEX). In this case, anyone can transparently check the status of the collateral on the block chain. On the other hand, if the loan is in fiat currency, the exchange may be a fiat currency-based centralized exchange that trades derivatives such as stocks or commodities, etc. For example, in the present invention, the borrower uses Samsung Electronics stocks in-kind as collateral. As another example, in the case of foreign exchange transactions, the borrower deposits Korean won as collateral, and the borrower deposits Korean currency as collateral, and provides a secured loan by investing in the corresponding futures product according to the two-way deposit ratio selected by the borrower. A secured loan can be configured to borrow dollars.

Currently, there are many centralized exchanges that can make two-way deposits among cryptocurrency exchanges. In December 2017, the Chicago Mercantile Exchange (CME) and the Chicago Board of Trade (CBOT) started trading Bitcoin futures. In addition, centralized platforms such as BitMEX (https://www.bitmex.com), OKEX (https://www.okex.com) and Binance (https://www.binance.com) The exchange supports derivatives and margin trading using Bitcoin as an underlying asset, and currently provides sufficient trading volume. However, the current trading volume of DEX, which trades cryptocurrency derivatives, is very low. For example, DEXs that support Ethereum derivatives include dxdy exchange (https://trade.dydx.exchange) and synthetix exchange (https://synthetix.exchange). And there are many more fiat-based assets or products or foreign exchange exchanges for applying the two-way deposit according to the present invention.

Now let's look at the forced liquidation of the system 12 according to the present invention,

In existing secured loans, all loans are part of the change in value. For this reason, if the value of collateral falls, the loan may be forcibly terminated by forced liquidation to forcibly collect the loan amount. In the aforementioned DAI, the liquidation price is determined by the liquidation rate. For example, since the liquidation rate of DAI is 150%, forced liquidation occurs when the value of collateral arrives at 150% of the loan amount. In this case, if the LTV of the loan is 30%, a forced liquidation occurs when the value of the collateral falls to 45% compared to the time of the loan.

According to another embodiment of the present invention, although forced liquidation occurs for the loan amount of the variable value portion, the loan amount of the fixed value portion may be determined so that forced liquidation does not occur. In the case of the examples in Tables 1 and 2, the loan amount, that is, the LTV, is determined so that forced liquidation does not occur in the fixed value part. For example, in Tables 1 and 2, since the LTV of the fixed value part is 95%, even if the collateral price changes after the loan, insolvency (default) for this part does not occur at all. Under these conditions, if only the fixed value part of the loan is included, it is advantageous to implement a secured loan without forced liquidation. This is a very good advantage of the secured loan according to the present invention that the existing secured loan does not have. For example, at a deposit ratio of 70:30 in Table 1, the loan includes only the fixed value portion of the collateral ($6,000), multiplied by the corresponding LTV (95%), to be $5,700. Therefore, in this case, there is no forced liquidation in the secured loan according to the present invention, and the LTV is 57%, which is higher than the LTV (30%) of the existing cryptocurrency secured loan. In contrast, in Table 1, at a deposit ratio of 90:10, the loan includes both a variable value portion ($1,333) and a fixed value portion ($1,900). In this case, the variable value portion and the fixed value portion of the collateral were $8,000 and $2,000, respectively. Therefore, in this case, there may be a forced liquidation of the value change part.

Table 2 shows the liquidation price and forced liquidation of the value-changed portion of the loan at various two-way deposit ratios (collateral: 1 BTC, the underlying asset at the time of loan, the price of BTC products and inverse BTC products: $10,000, liquidation ratio: 120 %) However, Table 2 includes all assumptions in Table 1.

In Table 2, if there is a forced liquidation of the value change part, it is set so that the liquidation occurs when the price of the underlying asset changes by ±64% compared to the time of loan. Because of this, the forced liquidation price would be $3,600 or $16,400. In other words, in the table, when the price of the underlying asset reaches ±64%, the liquidation price is set so that compulsory liquidation occurs in all value fluctuations. In this case, compulsory liquidation occurs within the same fluctuation range (±64%) of the price of the underlying asset after lending in all two-way deposit ratios. That is, another embodiment according to the present invention may be such that the compulsory liquidation of the value change part occurs in the same range of fluctuations in the price of the collateral.

Although this method is only one embodiment, it provides a great advantage that the borrower can easily predict the timing of the forced liquidation. This liquidation price is specifically the price at which forced liquidation occurs at both extremes of the two-way deposit ratio (100:0, 0:100). This is calculated by multiplying the value of the collateral ($10,000) by the LTV (30%) and the liquidation rate (120%) at the deposit rates at both extremes of the loan. Of course, since the LTV (30%) in this case is just one example, the borrower may take on a higher risk of forced liquidation and get a higher loan than this.

The most important feature of the computing system according to the present invention is that, unlike the existing loan service, the borrower can select the bidirectional deposit ratio so that the fixed value part is included in the loan amount. In this case, the loan amount can be determined in two ways.

The first is, if possible, a way to include a value change portion of the loan in the loan amount. The examples in Tables 1 and 2 used this method. However, in this case, forced liquidation will inevitably occur from the loan amount in the portion of the change in value. However, the loan amount of the fixed value part is different. If the LTV of the loan is determined as shown in Tables 1 and 2, the loan of the fixed value portion can continue to provide loan services regardless of forced liquidation. For example, if the price of the underlying asset falls from $10,000 to $3,600 at the deposit ratio of 90:10 in Table 2, forced liquidation occurs. In this case, as shown in Table 2, if the value of the value change portion during the loan decreases from $8,000 to $1,600, forced liquidation occurs. However, even if such forced liquidation occurs, the computing system can be configured so that the loan for the fixed value portion of the loan can be maintained.

Second, unlike Table 2, the loan includes only one of these two parts. As an embodiment, in the deposit ratios of both extremes, the loan may include only the value-variable portion, and the loan in other cases may include only the fixed-value portion. To this end, the computing system can be configured such that the bidirectional deposit ratio selected by the borrower is also set only at an interval of 10%. In this case, compulsory liquidation occurs only at the deposit ratios of both extremes, and there is an advantage that forced liquidation does not occur at all other two-way deposit ratios. In other words, this example has a great advantage that existing secured loans do not have because permanent loans are possible in all cases except for the deposit ratios of both extremes. However, this method has the disadvantage of reducing the loan amount compared to the first method. For example, in Table 1, at a deposit ratio of 90:10, only the fixed value portion ($1,900) of the loan is paid, and the other portion of the loan ($1,333) shown in Table 1 is not paid, so the LTV is reduced to 19%. However, this disadvantage only occurs when the two-way deposit ratio is largely concentrated in one direction, as shown in Table 1.

Next, let's find out why the loan amount for the value change part in the 90:10 deposit ratio in Table 1 is $1,333. The change-of-value portion of the loan occurs when the underlying asset reaches its liquidation price ($3,600) at $10,000 at the time of the loan. Similarly, compulsory liquidation occurs when the value of the variable value of collateral during a loan ($8,000) falls to $6,400, which is the same fluctuation range (64%) that compulsory liquidation occurs. Therefore, as shown in Table 2, when the value of the collateral is reduced to $1,600, a forced liquidation occurs, and the loan amount is calculated by dividing this by the liquidation ratio (120%). As such, the loan amount of the variable value part can be calculated only by first determining when the forced liquidation will occur.

Therefore, as an embodiment according to the present invention, the collateral recognition ratio of the value change portion in the system may be configured to be determined based on the liquidation price at which forced liquidation occurs.

Hereinafter, let's find out in detail the cryptocurrency-secured loan using the two-way deposit method according to the present invention through the issuance and liquidation process of ALFA. Here, ALFA, like DAI, is a stablecoin that is provided with collateral from the borrower in the secured loan according to the present invention and is newly issued and paid as the loan.

3 and 4 are diagrams illustrating an embodiment of a control method of a cryptocurrency secured loan using a two-way deposit of collateral according to the present invention.

According to the illustrated embodiment, the borrower terminal 11 that entrusts Bitcoin (BTC) as collateral and receives ALFA as a loan, the computing system 12 (operator) that pays the loan, and the borrower's deposit of the Bitcoin bidirectionally It consists of an exchange 15 that can trade derivatives such as futures for investment. Accordingly, this is to add a two-way deposit function by newly including an exchange for two-way depositing of collateral in the structure of the existing general secured loan of FIG. 1 .

Referring to FIG. 3 , in the method of controlling the secured loan according to the present invention, the borrower terminal 11 selects the ratio of the rising deposit and the falling deposit (70:30 in the illustrated example) and applies for a loan by transferring Bitcoin (S301) ) to start That is, the borrower selects to invest $7,000 and $3,000 in the rising and falling deposits, respectively, and transmits them to the operator (the computing system 12). That is, the bidirectional deposit ratio, which is the ratio of the falling deposit and the rising deposit, is set by the borrower terminal.

In the example shown, the operator (computing system 12) stores $7,000 of Bitcoin as an upward deposit (S302, upward deposit) at the exchange, and the remaining $3,000 Bitcoin moves to the exchange for a downward deposit (S303). Invest in relevant derivatives. However, in the case of FIG. 3, it is shown that after all collateral ($10,000) is provided to the operator 12, they are transmitted to the exchange. However, it is self-evident that the collateral may move directly from the borrower 11 to the exchange 15 otherwise. In addition, the rising deposit ($7,000) may be deposited in the operator 12 instead of the exchange if there is no leverage unlike the illustrated example.

Next, the operator (the computing system 12) newly issues 5,700 ALFAs corresponding to $5,700 as a loan (S304) and pays the borrower (S305), and the issuance process ends. Therefore, in the drawing shown, the LTV in the loan is 57%. And ALFA is a stablecoin whose value is fixed at one dollar. 3 and 4 correspond to the example of 70:30 in Table 1.

In step S305, the processing unit 12a may process the loan to be paid in fiat currency or cryptocurrency. As in the example shown in FIG. 3 , when paid in cryptocurrency, it may be a stablecoin newly issued based on the collateral. Alternatively, the cryptocurrency may be a cryptocurrency such as Tether already issued by a third party.

As for the upward deposit described in FIG. 3, if there is no leverage, the corresponding bitcoin may be simply deposited on the exchange, but if leverage exists, it is possible to deposit upward through margin trading, derivatives, funds, or securities. it will be self-evident Of course, the down deposit is invested in the corresponding derivatives of the exchange.

In the case of the above-described DAI, leverage can be used by repurchasing Ethereum with the loan paid by the borrower and receiving a loan repeatedly. However, the control method of the secured loan according to an embodiment of the present invention can provide the borrower with a leverage function to the borrower terminal more easily by investing the collateral in an investment product having leverage on the exchange.

Alternatively, the computing system 12 may further receive a leverage setting request from the borrower terminal 11 . The leverage setting request means a request for setting a leverage ratio for the up-deposit in step S302 or the down-deposit in step S303. In this case, the computing system may receive the leverage in step S301.

For example, if the borrower terminal 11 requests to set the leverage ratio to 2x, the computing system 12 applies twice the requested leverage ratio even at the time of the rising deposit (S302), and similarly, the lowering deposit (S303) This means that twice the requested leverage ratio is applied. Alternatively, the leverage of the rising deposit and the falling deposit may be configured to be set differently. According to another embodiment, the leverage is applied only to the two-way deposit ratios (100:0, 0:100) of both ends, and the loan may not be paid. Because leverage is for speculative purposes, borrowers can use leverage for speculation without taking out a loan.

If the borrower has invested all of the collateral in a rising deposit with double leverage, as shown in Table 1, if the price of Bitcoin is 15,000 and $5000, the price of the product will be 20,000 and $0, respectively, so the PNL Ratio is Each is ±100%. This represents a doubling of the P&L ratio compared to the case without leverage in Table 1. It is self-evident, however, that the borrower may assume this risk, as this increases the risk of the borrower being forced into liquidation.

4 shows an example of the liquidation process of the secured loan control method according to the present invention by the borrower. The borrower terminal 11 returns all 5,700 ALFA, which is the loan, to the operator and requests liquidation (S401). The computing system 12 receiving the liquidation request checks whether all of the loan amount (ALFA) has been recovered, and if confirmed, incinerates all the ALFAs returned from the borrower terminal 11 ( S402 ). Then, the computing system 12 recovers all of the collateral invested in both directions from the exchange (S403), returns it to the borrower as a recovery money (S404), and ends the liquidation process. In the case of the drawing, the recovery amount is BTC. Then, all of the issued ALFA is incinerated, and the processes of FIGS. 3 and 4 do not affect the total issuance of ALFA at all.

As collateral according to an embodiment of the present invention, bitcoin, which has the smallest price volatility among cryptocurrencies, may be used. The advantage of Bitcoin is that it has the lowest price volatility among cryptocurrencies as well as the most developed cryptocurrency trading market such as derivatives for two-way depositing of collateral. This is because it is possible to reduce excess collateral by selecting collateral with low price volatility in collateralized loans. Meanwhile, the present invention is not limited thereto, and other cryptocurrencies such as Ethereum may be used as collateral in the future. In addition, the collateral according to the present invention may be any asset or product capable of bi-directional deposit based on fiat currency.

As described above, in one embodiment of the present invention, a stablecoin is proposed as a cryptocurrency for the loan. Hereinafter, the characteristics of stablecoins will be described in more detail.

Stablecoins can be fixed in price by an exchange method. In this case, the exchange exchanges the stablecoin at a fixed price. For example, on this exchange, ALFA can be exchanged for Tether at a fixed 1:1 ratio. In this case, the price fixing of ALFA will depend on the arbitrage of users. Reliance on arbitrage means that the price can be fixed through the process of users buying ALFA at a lower price on this exchange and other exchanges and selling it at a higher price to make a profit.

Furthermore, the computing system 12 according to an embodiment of the present invention may be configured as a smart contract or DApp executed in a block chain to transparently disclose the state of collateral to the block chain. . This can be implemented so that the transfer details of Bitcoin as collateral and the amount of issuance of ALFA can be checked directly on the corresponding blockchain network.

3 and 4 are only one example of a cryptocurrency secured loan. The present invention can also be applied to secured loans based on legal currency such as stocks. For example, the borrower deposits Samsung Electronics stocks, receives the loan in fiat currency, and invests in the product according to the two-way deposit ratio in an exchange that trades Samsung Electronics' derivatives at the two-way deposit ratio specified by the borrower. can do. Accordingly, according to the present invention, when the borrower provides the operator with the asset traded in the fiat currency-based spot market and the two-way deposit ratio, the operator can operate the asset in a way that invests the asset in the corresponding derivative according to the two-way deposit ratio. Therefore, the present invention is not limited to the case where the collateral is cryptocurrency, but can be applied to any asset, currency, or product that can be deposited in both directions. That is, if there is an exchange that is a commodity such as crude oil or a foreign exchange transaction (FX) and can deposit in both directions, the collateral loan system and control method according to the present invention may be applied. Therefore, according to the present invention, the collateral and the loan can be deposited in both directions, regardless of the type or form, and can include everything that is transacted.

Advantages of the computing system according to an embodiment of the present invention will be described below.

1) The present invention provides the borrower with a new two-way deposit function that allows the borrower to select the direction of rising and falling prices of collateral to obtain profits. Accordingly, the present invention provides a computing system and a control method in which a borrower can select a two-way deposit ratio of collateral according to their investment propensity and obtain investment results therefor.

2) The present invention can provide borrowers with a new type of secured loan in which forced liquidation does not exist. This is because the present invention can provide this in such a way that the loan includes only the new fixed value part that is not in the existing secured loan.

3) The present invention provides borrowers with a new means to reduce the risk of forced liquidation by adjusting the ratio of two-way deposits. Since the volatility of the value of collateral decreases as the ratio of upward and downward deposits becomes similar, this method provides borrowers with a means to reduce the high price volatility of cryptocurrencies.

5 shows an embodiment of an investment by two-way deposit between a borrower's wallet and an operator's wallet during a loan according to the present invention.

The figure shows that the borrower's wallet 21 controlled by the borrower terminal 11 provides collateral, and the operator's wallets 22 and 23 under the control of the computing system 12 according to the present invention are provided with the collateral. shows an example of the process of investing by two-way deposit.

Specifically, the drawing shows that the borrower terminal 11 provides a two-way deposit ratio (70:30) and 1 BTC as collateral and applies for a loan (S501), then the borrower's wallet 21 controlled by the borrower terminal 11 ) shows an embodiment in which 1 BTC as collateral is transferred to the operator wallet 22 controlled by the computing system 12, and then 0.3 BTC, which is a part of the collateral, is invested in a downward deposit. In the figure, in the investment by two-way deposit, 0.7 BTC is deposited in an upward deposit according to the two-way deposit ratio (70:30) of the collateral that arrives at the operator's wallet 22, and the rest is deposited in a falling deposit (S502). Specifically, the upward deposit is kept in the operator's wallet 22 as it is, and the downward deposit is transmitted to the operator's exchange wallet 23 controlled by the operator, and then it is linked to -1x of the underlying asset (BTC). It is exchanged for the HEDGE token, which is a waste (S502), and it is returned to the operator's wallet 22 (S504) and stored. In the drawing, the number of exchanged heads is indicated by '?'.

As a result of the S501 ~ S502, the final state of the operator wallet 22 is '? HEDGE' is stored.

Therefore, in the above diagram, if the leverage is 1, therefore, the downward deposit uses a method of holding a 1x short product (HEDGE) that moves in the opposite direction to the price of BTC, the underlying asset. In this regard, BEAR(-3x) and BULL(3x) tokens, which are cryptocurrencies that move 3x against the underlying asset (BTC), are currently trading in the market. Therefore, according to the embodiment of Fig. 5, it will be possible to expand the application as a method of investing collateral in a leveraged product. Since these tokens are like Exchange Traded Funds (ETFs) based on existing fiat currencies, these tokens can also be viewed as cryptocurrency ETFs with cryptocurrencies as an underlying asset. Cryptocurrency tokens with these EFT characteristics are sufficiently traded in the current market. In addition, cryptocurrency tokens with this leverage function are also traded on exchanges other than Bitcoin (BTC) linked to other cryptocurrencies such as Ethereum.

5, the operator's exchange wallet 23 according to the present invention may be a wallet that supports derivatives or margin transactions under the control of the operator. In this case, the two-way deposit according to the present invention can be performed by investing in futures products traded on the exchange. In this case, the collateral invested by the two-way deposit is stored in the operator's exchange wallet 23.

In particular, in an embodiment of the present invention, it is proposed that the borrower terminal 11 directly selects an investment item for depositing up or down. That is, it means that the borrower terminal 11 can directly select a desired investment item from the exchange and apply it to a rising or falling deposit. To this end, the computing system 12 according to an embodiment of the present invention receives a request to change the collateral from the borrower terminal 11, but the request for changing the collateral includes products (gift products, etc.) or assets (other other products) traded in the exchange. It is proposed to include item identification information for identifying cryptocurrencies, etc.).

In this embodiment, the collateral change request refers to a request to change to another product or asset in order to deposit the received collateral up or down. In other words, the borrower selects a stock to be applied to a rising or falling deposit, and requests a collateral change so that the currently provided collateral is changed to the selected item.

To this end, in an embodiment of the present invention, the processing unit 12a receives a request for changing the collateral from the borrower terminal 11, and the request for changing the collateral is item identification for identifying products or assets traded in the exchange. may contain information. In this case, the item identification information is information for identifying the type of collateral that the borrower terminal 11 wants to change, and may be, for example, the name of a product or asset traded in a corresponding exchange. In addition, the processing unit 12a may exchange some or all of the provided collateral for products or assets corresponding to the item identification information in the exchange. In addition, the processing unit 12a may invest in at least one of the rising deposit or the falling deposit as the exchanged product or asset.

As in one embodiment of Figure 5, in one embodiment of the present invention, the upward deposit may include keeping the collateral for the loan period.

In particular, in one embodiment of the present invention, further specifically, it is proposed to separately designate the item to be designated as the rising deposit and the item to be designated as the falling deposit by the borrower terminal 11, or to designate a leverage ratio. In the investment as the rising deposit and the falling deposit, it means that two or more items of the investment may be configured. For example, the processing unit 12a invests in Bitcoin and Ethereum together in a rising deposit and a falling deposit.

And the investment as a rising deposit or a falling deposit may be configured in the form of a basket (provided in the form of a list) to include one or more stocks. Accordingly, the borrower terminal may select one or more of the investment items in the basket (list) and provide it to the computing system 12 to change the collateral to the selected investment item.

To this end, the collateral change request may include 1) name information (and/or identification information) of the product as a rising deposit and a falling deposit, and 2) information on the leverage ratio of the product. That is, the borrower terminal 11 may provide such information to the computing system 12 together with the bidirectional deposit ratio. Here, the product may be a derivative product, a margin transaction, or a product traded on an exchange, such as an ETF. To this end, the borrower terminal 11 according to the present invention provides name information (identification information) of the collateral to be exchanged, that is, name information of each of the rising deposit product and the falling deposit product.

All or part of the collateral is exchanged for other cryptocurrencies such as Ethereum (ETH) in accordance with the two-way deposit ratio and the collateral change request provided by the borrower terminal 11, and the exchanged Ethereum is exchanged according to the two-way deposit ratio You can invest in a rising or falling deposit. For example, if the borrower terminal 11 provides 1 BTC to the computing system 12 as collateral when making a loan, 70% of the provided collateral, 0.7 BTC, is invested as a rising deposit in a product following 3 times the leverage, and the remaining 0.3 BTC can invest in products that track -1 times of Ethereum (ETH). This means that you can invest up and down deposits in different stocks (different instruments or different leverage).

6 is a diagram illustrating a liquidation procedure according to an embodiment of the present invention.

The processing unit 12a according to an embodiment of the present invention receives a liquidation request having a condition not to return some or all of the loan from the borrower terminal 11 (S601), the investment in the exchange Processing (S602, S603, S604) is performed so as to recover a portion of the collateral that meets the above conditions. Then, in the recovered collateral, the remaining collateral after deducting the portion corresponding to the shipbuilding of the loan may be settled and returned to the borrower terminal 11 ( S605 ) to complete the liquidation.

To this end, the computing system 12 according to an embodiment of the present invention includes a communication unit 12c for connecting to a network for transmitting and receiving data with the borrower terminal 11 and the exchange 15 and data related to the loan. a storage unit (12b) for; and a processing unit 12a for processing a loan payment in response to a loan request received from the borrower terminal 11 , receiving collateral from the borrower terminal 11 and processing the loan in the borrower terminal 11 . In order to do this, the processing unit 12a is, when a liquidation request having a condition not to return part or all of the loan money is received from the borrower terminal 11, a portion of the collateral invested in the exchange that corresponds to the condition The liquidation may be completed by processing the recovered collateral and returning the remaining collateral to the borrower terminal 11 after deducting the portion corresponding to the above conditions among the loan amount.

Here, the processing to recover the collateral refers to selling the collateral invested by the two-way deposit at the exchange (S603) and returning it as the recovery money (S604). Here, the recovery money may be a stablecoin, cryptocurrency such as collateral, and fiat currency depending on the purpose of the recovery.

In a general secured loan, liquidation is started when the borrower terminal 11 returns all the loans borrowed to the computing system 12, which is an operator, and requests liquidation. It is self-evident that the computing system 12 according to an embodiment of the present invention may also process liquidation in this existing method.

However, in addition to this existing method, in an embodiment related to FIG. 5 , the borrower terminal 11 proposes to make a liquidation request without returning the loan to the computing system 12 . That is, when such a liquidation request is received from the borrower terminal 11 (S601), the computing system 12 sells all the invested collateral at the exchange (S603), collects it and prepares a recovery money, and subtracts the loan amount from the recovery money Returning the settlement money obtained by calculating the remaining collection amount to the borrower terminal 11 (S605). That is, the borrower terminal 11 will be able to settle the loan in a simple way without returning the loan amount.

The processing unit 12a according to an embodiment of the present invention pays the loan in a predetermined kind of stablecoin, and in the case of forced liquidation, which is expected to lack the value of investment in the falling deposit and the rising deposit, the forced liquidation occurs. The collateral that is forcibly recovered by liquidation may be stored as at least one of a different kind of stablecoin from the loan or the fiat currency, so that the issued stablecoin is continuously circulated in the market without incineration. That is, when forced liquidation occurs, it is common for stablecoins corresponding to the forced liquidation to be burned. However, the present invention is to exchange the recovered collateral with other types of collateral so as not to incinerate the stablecoins corresponding to the forced liquidation even if forced liquidation occurs.

In addition, the computing system 12 according to another embodiment of the present invention includes a communication unit 12c for connecting to a network for transmitting and receiving data with the borrower terminal 11 and the exchange, and a storage unit for storing loan-related data ( 12b); and a processing unit 12a that processes to pay a loan in response to a loan request received from the borrower terminal 11, and receives a collateral from the borrower terminal 11 to process the loan to the borrower terminal 11 In order to do this, the processing unit 12a pays the loan as a first stablecoin and collects the collateral recovered by the forced liquidation when a forced liquidation that is expected to lack the value of the investment as the falling deposit and the rising deposit occurs. It is characterized in that the first stablecoin of the loan is exchanged with at least one of the second stablecoin or the fiat currency, which is different from the first stablecoin. This is because the total issuance of the first stablecoin is fixed constant.

In general, when a forced liquidation occurs in a secured loan that provides stablecoins as a loan, the computing system 12 sells the collateral at the exchange to purchase the corresponding number of stablecoins, and burns all the purchased stablecoins. do. This is a method of recovering the loan as liquidation through forced liquidation. This existing method reduces the total number of stablecoins circulating in the market, making the secured loan always maintain excess collateral. Therefore, this method is a method of reducing the total number of stablecoins circulating in the market by the amount of the reduced loan when the total loan amount is reduced by forced liquidation.

However, the computing system 12 according to an embodiment of the present invention exchanges the liquidation money by forced liquidation, that is, the collateral recovered by the forced liquidation, with at least one of the loan and other types of stablecoins or fiat money, in addition to these existing methods. can be kept Another kind of stablecoin means that if the computing system 12 paid a kind of stablecoin called ALFA as a loan, the collateral recovered by forced liquidation is exchanged for ALFA and Tether, which is a different kind of stablecoin. . And the computing system 12 is to keep the tether as new collateral for the forcibly liquidated loan. In this way, there is no need to purchase new stablecoins in circulation and burn them. This is because this is because the collateral recovered by forced liquidation is sold at the exchange 15 to purchase other types of stablecoins or fiat currency and store them as new collateral. This has the advantage that the total number of stablecoins provided as loans does not decrease even if forced liquidation occurs.

The other type of stablecoin is pegged to the same fiat currency or asset as the loan amount. For example, in FIG. 3, 1 ALFA is a stablecoin pegged to 1 US dollar. Therefore, as the other types of stablecoins, the coins pegged to the US dollar may be Tether, USDC, DAI, and the like, and these are the exchanged collateral. Accordingly, the exchanged collateral does not fluctuate in value over time, so it has exactly the same value as the stablecoin provided as a loan.

The processing unit 12a according to an embodiment of the present invention receives the bi-directional deposit ratio again from the borrower terminal 11, and calculates the ratio of the falling deposit and the rising deposit according to the received bi-directional deposit ratio again. By changing and investing, the two-way deposit ratio can be changed again without paying off the loan. This is to provide the borrower terminal 11 with a function of changing the two-way deposit ratio of the collateral already invested in the borrower terminal 11 when the market situation changes and the borrower terminal 11 wants to adjust the two-way deposit ratio of the invested collateral. am.

The exchange 15 shown in FIGS. 3 to 6 may use the operator's exchange wallet 23 which is operated by a third operator and can only be controlled by the computing system 12 . Alternatively, the exchange 15 may be configured such that the computing system 12 controls and operates the entire system of the exchange.

The computing system 12 according to the present invention can pay more loans than the existing secured loan system under the same compulsory liquidation conditions. This is not in the existing secured loan system, but it has an advantage because of the value fixed part, which is a newly included hedged part because of the two-way deposit function.

To understand this, let's look at how the loan amount is determined. First, in the existing secured loan system (FIG. 1), the loan amount is determined by the LTV (Security Recognition Ratio). If the LTV is 30% as shown in FIG. 1 , since 30% of the value of the collateral is paid for the loan, the forced liquidation occurs when the price of the collateral falls to 70% compared to the time of the loan. Therefore, in this system, the LTV decides when the loan amount and forced liquidation occurs.

On the other hand, the loan amount in the computing system 12 according to the present invention is determined by the forced liquidation rate, not the LTV. However, the compulsory liquidation ratio is defined as the ratio of the value of the collateral in which the compulsory liquidation occurs to the value of the collateral at the time of loan. For example, if the liquidation ratio is 70% and the value of the collateral at the time of the loan is $10,000, the liquidation occurs when the value of the collateral falls to $3,000 after the loan. Therefore, the compulsory liquidation ratio according to the present invention determines when the loan and forced liquidation occurs. That is, the processing unit 12a of the computing system 12 determines the occurrence time of the forced liquidation caused by the lack of value of the collateral after the loan as the forced liquidation ratio, and the forced liquidation rate is the forced liquidation of the value of the collateral at the time of loan. It is the ratio of the value of the collateral at the time of occurrence.

And in the system according to the present invention, the LTV varies depending on the investment ratio, even if the compulsory liquidation ratio is the same as shown in Table 3. The loan amount can be determined in two different ways at the same compulsory liquidation ratio. First, the existing method is As a method used in existing secured loans, the loan amount is determined by calculating the value of the entire collateral.For this reason, forced liquidation occurs in the entire collateral.Secondly, the separation method divides the collateral into a fixed value part and a variable value part and pays the loan amount. This allows the loan to be determined so that forced liquidation only occurs on the part of the change in value.

Table 3 shows the loan amount calculated by the conventional method. However, in this table, the borrower terminal entrusts 1 BTC of Bitcoin as collateral, and the computing system 12, which is the operator, uses this collateral as a rising deposit and a falling deposit, respectively, in the upward direction for the spot price (or underlying asset price) of Bitcoin. and (1x) long positions and (-1x) short positions that follow exactly 1x in the downward direction. Therefore, in this embodiment, the rising deposit keeps the collateral in the wallet as it is. In addition, it is assumed that the price of both the underlying asset and the investment product is $10,000 at the time of loan, and an ideal situation is assumed with no fees.

In this method, in order to determine the loan amount, you must first select a forced liquidation ratio. In this table, the forced liquidation rate is set at 70%. Next, the value of the entire collateral is calculated from the forced liquidation ratio. As shown in Table 3, when the price of the underlying asset changes by ±70%, the value of collateral is calculated at various two-way investment ratios. That is, the value of the loan is calculated from the price at which forced liquidation occurs. The loan becomes the collateral value (indicated in italics in Table 3) when the market moves in the opposite direction of the borrower's bet. This is because the collateral is forcibly liquidated in a situation where the betting direction is wrong, but in the opposite case, the borrower will receive a profit. Therefore, the betting direction refers to the investment ratio that includes more collateral among the two-way deposit ratios when lending. For example, in a (two-way) investment ratio of 70:30, the collateral has an upward deposit (70%) than a downward deposit (30%), so the betting direction is an upward deposit, and thus forced liquidation occurs when the price of the underlying asset decreases. do.

The big advantage that can be found in this table is that the loan amount increases significantly as the two-way deposit ratio approaches 50:50 at the same forced liquidation ratio (70%). That is, as shown in Table 3, the LTV increases from 30% to 100%. In addition, in Table 3, the bidirectional deposit ratio (100:0) including only the upward deposit is the existing secured loan. Therefore, in the table, the existing secured loan corresponds to the case where only the rising deposit is included among the various two-way investment ratios of the new secured loan. And its LTV (30%) is the smallest among the various interactive investment ratios.

Table 3 shows the loan amount calculated by the conventional method when the forced liquidation ratio is 70%. In this table, the reason the loan amount is different under the same compulsory liquidation conditions, that is, the same compulsory liquidation ratio, is because the value of the collateral includes a new fixed value part. Existing secured loans cannot contain this fixed value part. In conclusion, as the ratio of the fixed value part of the total collateral increases by the two-way deposit ratio, the loan amount also increases proportionally. Taken together, the advantage of the system 12 according to the present invention is that it can pay more loans than the existing secured loan system by using the amount "?* deposit function.

Table 4 shows the loan amount calculated by the separation method when the forced liquidation ratio is 70%. However, the calculation conditions in this table are the same as in Table 3. This separation method is calculated by dividing the collateral and the loan into a stable portion and an unstable portion.

In this method, the loan is calculated from the collateral. That is, the fixed value part of the loan is calculated from the same part of the collateral. Since the value of the collateral does not fluctuate in this part, the computing system can pay the loan up to the maximum amount of the collateral value under ideal conditions, so that there is no shortage of collateral in this part. In Table 4, the loan for this part paid the maximum amount. Because of this, the LTV becomes 100% at the 50:50 bidirectional deposit ratio in the table.

The change in value of the loan is determined by the forced liquidation ratio. However, in Table 4, the forced liquidation ratio is assumed to be 70%. If the value of the collateral is reduced by 70% compared to the time of the loan due to the compulsory liquidation conditions, this value change part is forcibly liquidated. We use these characteristics to calculate the loan amount for this part. That is, when the price of the collateral reaches the liquidation ratio, if this part of the collateral still has value, the remaining part becomes the loan. In other words, if the value of the variable value part of the collateral is negative, there is no loan for this part. Let's apply this to Table 4. In this table, since the collateral is 1 BTC and the forced liquidation ratio is 70%, when the value of the collateral is more than 0.7 BTC when it arrives at this ratio, this large part becomes a loan, and if it is less than this, there is no loan for this part at all . For example, in the 90:10 deposit ratio in Table 4, the value of the collateral is 0.8 BTC, so 0.1 BTC minus 0.7 BTC is the loan amount for this part. As another example, in a (two-way) deposit ratio of 70:30, the value of the collateral part is 0.4 BTC, which is less than 0.7 BTC, so there is no loan for this part. The total loan amount is calculated by adding up the two parts and multiplying this by the price of the collateral at the time of the loan.

The advantages of the computing system 12 indicated by Table 4 are as follows. First, as in Table 1, as the bidirectional deposit ratio approaches 50:50, the loan amount increases significantly. This is an advantage that occurs because the fixed value is increased by the two-way deposit function. In summary, the advantage of the present computing system 12 that can be seen through Tables 3 and 4 is that it can pay more loans than the existing secured loan system. Another advantage is that in the two-way deposit ratio (80:20-20:80) indicated in italics in Table 4, the loan includes only the fixed value portion. Therefore, there is no shortage of collateral in this case.

However, there is a difference in the amount of loans made by these two methods. That is, the loan amount in Table 4 is smaller. The difference between them is indicated in the last column of Table 4 and is maximized at the bidirectional deposit ratios of 80:20 and 20:80. If the compulsory liquidation ratio is very high as shown in Table 4, in most of the two-way deposit ratios, the loan includes only the fixed value part. . In this case, not only will the loan amount increase due to the reduced forced liquidation ratio, but also the loan amount will increase due to the newly included value change. Of course, setting the compulsory liquidation rate at 70% is only an example.

Next, the two-way deposit function can be implemented in a decentralized way using leveraged tokens issued by ftx.com. These tokens are ERC-20 tokens issued on the Ethereum network and are a kind of ETF product. Examples of these tokens are HEDGE (-1x), BULL (+3x) and BEAR (-3x) linked to the price of the underlying Bitcoin, HEDGE (-1x), ETHBULL ( +3x) and ETHBEAR(-3x). Therefore, these tokens can be used for the two-way deposit function. If this is applied to the example of FIG. 3, it is as follows. First, when the borrower terminal transmits 1 BTC and a two-way deposit ratio (0.7:0.3) as collateral, the computing system, the operator, stores 0.7 BTC in the operator's wallet 22 to deposit the collateral, and the remaining 0.3 BTC is After exchanging for HEDGE at the cryptocurrency exchange, it is stored in the operator's wallet 22 to complete the investment of collateral. Therefore, this example invests the collateral in a product that tracks the collateral at exactly 1x in both the up and down directions. Conversely, in the case of liquidation, HEDGE is exchanged for Bitcoin at the exchange and then the entire collateral is transferred to the borrower's terminal.

In this embodiment, the collateral and the investment product are the same. In other words, if the collateral is Bitcoin, the two-way deposit function also uses Bitcoin. However, otherwise, in the present invention, the collateral and the investment product may be different from each other. In other words, borrowers can select investment products from a basket of various investment products. For example, if a borrower entrusts Bitcoin as collateral and selects Bitcoin (30%) and Ethereum (70%) for rising and falling deposits, respectively, the operator can execute the corresponding investment accordingly.
