Description

How to ensure the value stability of cryptocurrency

The present invention relates to a system and method for ensuring the value stability of cryptocurrency, and more particularly, a method for ensuring the value stability of cryptocurrency used in a decentralized application (DApp) that provides a service through a blockchain system. It is about.

Recently, Cryptocurrency technology uses a distributed ledger, such as Bitcoin, to send and receive value without a broker to record the execution result of a Turing complete programming language on the distributed ledger. It is evolving to a stage where a decentralized application (DApp (hereinafter also referred to as "Dap")) can be executed. Such a decentralized application can provide various services by the operation of the adapter (DApp) installed in each user's computer without going through a server through a network connected directly between the user's computers (Peer to Peer Network). DApp) is performed by a distributed ledger based on blockchain.

For example, a platform for decentralized decentralized applications (DApps), such as Ethereum (Ethereum, https://www.ethereum.org) is a good example, and users can use Ether, the platform's underlying token to use the platform. Service tokens issued by Leeum and each DApp will be paid to the distributed platform and Dapp, and the service will be provided.

Currently, very rudimentary DApps such as Kryptokitties (https://www.cryptokitties.co/) are in operation, but in the next three to four years various DApps, such as distributed storage, will be available. DApps are expected to provide distributed computing services, distributed exchanges, distributed social networks and chat services.

Service medium tokens that are issued to use as a service medium provided by these DApps usually have a fixed number of issues, the value of which is determined by the market and is quite unstable. This creates a great inconvenience for participants in the DApp ecosystem. For DApp service users, if a large number of tokens are purchased to reliably use DApps, they will be exposed to market risk. For those who provide services to users via), the price of the service, expressed as a token amount, must continue to be adjusted in real time to cover the cost of operating the system.

In the case of a low-margin type of DApp (eg, storage or computing services), if the service volatility is too high, the operator may see an unexpected deficit, preventing the market from becoming active.

Therefore, in order for DApp using a distributed platform to be widely used, it is necessary to have a separate device so that the value of a token issued by DApp and used as a service medium is maintained stably.

Meanwhile, as a method for stabilizing the token value, there is a method of creating a stablecoin having a stable value, such as a currency of the real economy, and using it as a service medium token of DApps.

There are three main ways to do this. The first is to guarantee the 1: 1 exchange of value stabilization tokens with assets such as gold and dollars by central institutions (Tether dollar, DigixDao, etc.). This method is heavily influenced by the stability of the central authority and the government's policies, and has the disadvantage that the system can collapse when the central authority is hacked.

The second is to use other cryptocurrencies as collaterals to guarantee the value of the value stabilization tokens and to pay off the collateral if the value falls below a certain percentage (Bitshares, MakerDAO, etc.). In this case, if the value of the cryptocurrency that is collateral falls, the value stabilization token is liquidated, causing inconvenience to use, or the assets of those who issued the value stabilization token based on the collateral in the process of recruiting additional collateral are unexpected. There is a problem of dilution. Therefore, when the value of cryptocurrency is unstable, the participation rate of the system decreases and sufficient value stabilization tokens are not issued, or a premium is attached to the price of the value stabilization tokens.

The third method is based on the monetary quantity theory, which is to issue a dominant token with the authority to issue a value stabilization token, measure the price of the value stabilization token circulating in the market, and issue it additionally if it is too expensive. It is a way to maintain the value of the value stabilization token by issuing a distribution to the distributor and trading too cheaply, by issuing additional tokens or by issuing a kind of bond to buy tokens temporarily in the market (Basecoin, Carbon, etc.). This method may operate more stably than the collateral-based method, but if the value of the value stabilization token falls in the market due to external shocks, problems may arise because participants do not purchase additional control tokens or bonds issued due to fear. . In addition, if the market suffers from chronic deflation, there is a problem that the buyer will disappear and the system will collapse because the possibility of further compensation to the controlling token or bond will be greatly reduced. In addition, depending on the design, there are cases where holders of dominant tokens are unavoidable to cause system instability and benefit from inflation / deflation.

For the above reasons, in the economy based on cryptocurrency technology, successful DApp ecosystem based on value stabilization token has not been established and the value of service media token used in the decentralized application environment based on blockchain. The problem is that there is no way to stabilize it.

The present invention is to solve the above problems, to provide a system and method that can effectively stabilize the value of the token (token) provided in a blockchain-based decentralized application (DApp) environment The purpose.

It is another object of the present invention to provide a method for allowing a service medium token issued by a DApp to always correspond to providing the same amount of service.

In addition, the present invention proposes a method for issuing a new value stabilization token that solves problems of existing value stabilization tokens, and provides a method for implementing the same in the form of a DApp.

In order to solve the above problems, the present invention is a method for ensuring the value stability of cryptocurrency used in a decentralized application (DApp, hereinafter referred to as "Dap") that provides a service through a blockchain system, In at least one node included in a chain system, a first step of receiving a adapter transaction from a user system for performing a service for the adapter and performing a adapter contract corresponding to the adapter transaction, wherein the adapter transaction is An amount of a service media token paid by a user to use the adapter; A second step in which at least one node included in the blockchain system performs a token contract by performing the dap contract to incinerate a portion of the amount of the service medium token included in the dab transaction; And at least one node included in the blockchain system evaluates the average payment amount of the service medium token for the unit service provided by the adapter by performing the token contract and adjusts the value of the service medium token according to the evaluation result. And a third step of: issuing and providing a service agent token to the controlling token holder when the average payment amount of the service agent token for the unit service provided by the adapter is smaller than a preset value. Step 3-1, wherein the governing token is a token having a right to be distributed a service agent token used in the dab; And a third step of reducing the supply amount of the service agent token by buying and incinerating the service agent token when the average payment amount of the service agent token for the unit service provided by the adapter is greater than a preset value. It provides a method for ensuring the value stability of cryptocurrency characterized in that.

Here, in step 3-2, if the average payment amount of the service medium token for the unit service provided by the adapter is greater than a preset value, the new governing token or the bond for the service medium token is issued. By issuing and buying and burning service media tokens in the market, the supply of service media tokens can be reduced.

In addition, the second step may be incinerated by a predetermined amount or by a dynamically adjusted amount.

Further, after the third step, the incineration amount or the incineration rate is decreased when the average payment amount per unit service provided by the adapter is smaller than a preset value, and the incineration amount or when the average payment amount per unit service is larger than a preset value. A fourth step of increasing the incineration rate may be further included.

According to another aspect of the invention, a method for ensuring the value stability of cryptocurrency used in the DApp (DApp) that provides a service through the blockchain system, at least one node included in the blockchain system, A first step of receiving a DAP transaction from a user system to perform a service for a DAP transaction and performing a DAP contract corresponding to the DAP transaction, wherein the DAP transaction is a service media token of a service paid by a user to use the DAP. Includes amount; In at least one node included in the blockchain system, a token contract is performed by performing the DAP contract, subtracting a portion from the amount of the service medium token included in the DAP transaction, and controlling a fee corresponding to the deducted amount. Distributing to token holders; And at least one node included in the blockchain system evaluates the average payment amount of the service medium token for the unit service provided by the adapter by performing the token contract and adjusts the value of the service medium token according to the evaluation result. And a third step of: issuing and providing a service agent token to the controlling token holder when the average payment amount of the service agent token for the unit service provided by the adapter is smaller than a preset value. Step 3-1, wherein the governing token is a token having a right to be distributed a service agent token used in the dab; And step 3-2 of reducing the supply amount of the service medium token by buying and incinerating the service medium token when the average payment amount of the service medium token for the unit service provided by the adapter is greater than a preset value. It provides a method of ensuring the stability of the value of a cryptocurrency characterized by

Here, in step 3-2, if the average payment amount of the service medium token for the unit service provided by the adapter is greater than a preset value, the new governing token or the bond for the service medium token is issued. By issuing and buying and burning service media tokens in the market, the supply of service media tokens can be reduced.

In addition, in step 3-2, instead of issuing a new dominant token, the token contract may borrow a dominant token from an existing dominant token holder who has a token lease contract in advance and use it to purchase a service token.

In addition, the fee may be differentially distributed to the controlling token holder who borrowed the controlling token according to the term of the lease.

In addition, the unit service provided by the adapter according to the execution of the token contract is to transmit the value of the legal currency preset per service medium token, and the third step is to the adapter by performing the token contract. It is possible to evaluate whether the average payment of the service medium token for the unit service provided by the service corresponds to the value of a predetermined legal currency, and adjust the value of the service medium token according to the evaluation result.

According to the present invention, it is possible to provide a system and method that can efficiently stabilize the value of a token provided in a blockchain-based decentralized application (DApp) environment.

In addition, the present invention may provide a method for the service medium token issued by the DApp to always correspond to providing the same amount of service.

In addition, it is possible to propose a method for issuing a new value stabilization token that solves problems of existing value stabilization tokens, and to provide a method of implementing the same in the form of DApp.

First, an environment in which the first embodiment of the present invention is performed will be described with reference to FIGS. 1 to 5.

1 to 3 show the overall system configuration for carrying out the first embodiment according to the present invention.

Referring to FIG. 1, the blockchain system 100 and the user system 200 are connected through a network.

The user system 200 refers to a device, such as a computer, a smartphone, and the like, which are known in the art, and the blockchain system 100 includes a plurality of distributed nodes directly connected to each other by a peer-to-peer communication protocol. , A network composed of a set of 10 to 60 or a plurality of distributed nodes 10 to 60.

2 is a diagram illustrating an example of a blockchain system 100.

As shown in FIG. 2, the blockchain system 100 is constituted by a plurality of distributed nodes 10 to 60, and the plurality of nodes 10 to 60 are connected to a Peer to Peer (P2P) communication protocol. Network is directly connected to each other.

Here, the plurality of nodes 10 to 60 may be physically devices such as a computer or a smartphone, and they may be of a shared ledger or smart contract by a predetermined consensus algorithm. Update the state variables corresponding to the execution result. In one embodiment, a new transaction or state variable is stored in the ledger described above in a set of blocks (blockchains) each of which has a structure in which at least one block is continuously connected like a chain. It may be provided with a virtual machine for performing a smart contract (smart contract).

Looking at the implementation of the blockchain in the prior art, such as Bitcoin or Ethereum, each block constituting the blockchain, the transaction (transaction) information that is the transaction history information between users through the blockchain system 100 Information is stored and may be composed of block headers and transactions, which are generated through proof of work by miner nodes and included in the blockchain.

Such a block, blockchain and blockchain system 100 itself is known by the prior art, and since it is not a direct configuration of the present invention, detailed description thereof will be omitted here.

However, the present embodiment is described based on the blockchain, but in other embodiments, the block or the blockchain is not necessarily required, and it is possible to maintain a shared ledger or state variables and prove something about past transaction or program execution. The system can also apply the present invention.

3 is a diagram illustrating an example of a configuration of a node.

Referring to FIG. 3, the nodes 10 to 60 include a communication unit 21, a block storage unit 22, a virtual machine 23, and a block generation unit 24.

The communication unit 21 is a means for performing a communication function with the blockchain system 100 and the user system 200, and the block storage unit 22 stores a block constituting the blockchain as described above. In charge of.

The virtual machine 23 is a means for executing a smart contract, and the block generator 24 is a means for generating a new block.

The configuration of such nodes 10 to 60 is also known by the prior art and is not a direct object of the present invention, so detailed description thereof is omitted here.

Referring back to FIG. 1, a user of the user system 200 uses a service provided by a decentralized application 300 in cooperation with the blockchain system 100.

Here, the decentralized application (Dapp, 300, hereinafter also referred to as "Dip 300") refers to the blockchain system 100 based on the blockchain system 100 without the intervention of a centralized server. In other words, it means an application that can provide a specific service based on a plurality of distributed nodes (10 to 60, see FIG. 2) constituting the blockchain system 100. For example, the adapter 300 may be an application that provides a service such as a financial transaction service, a game service, a file sharing service, a storage service, and the like based on the blockchain system 100.

The adapter 300 is known through the Ethereum blockchain platform, and in the existing blockchain platform such as Bitcoin, it is composed of code by programming, rather than storing only transaction details. It is an application that stores the "smart contract" that is to be stored and run it on the nodes constituting the blockchain system 100, so that the transaction details of the execution result of the smart contract can be reflected in the block.

As shown in FIG. 1, the adapter 300 includes a adapter user interface 210 and a adapter contract 110 that is a smart contract corresponding to the adapter.

 The adapter user interface 210 is an interface for a user to receive a service by the adapter 300 through communication with the adapter contract 110 of the blockchain system 100 through the user system 200. It may be a client program such as a wallet or the like.

The adapter contract 110 is a smart contract corresponding to the adapter 300 and is stored in the blockchain system 100 as shown in FIG. 1. The adapter contract 110 is a smart contract for providing a service by the adapter 300 and is stored in the blocks of the nodes 10 to 60 when the adapter 300 is distributed to the blockchain system 100.

A user uses a service provided by the adapter 300 by transmitting a transaction for performing a specific service and receiving a result thereof through the adapter user interface 210 of the user system 200 to the adapter contract 110. Done. The specific configuration and operation of the adapter 300 and the adapter contract 110 itself are well known in the existing blockchain system such as Ethereum, etc., which is not a direct object of the present invention, and thus detailed description thereof is omitted. do.

On the other hand, in the first embodiment of the present invention, the block chain system 100 is characterized in that the token contract 120 is additionally provided, the token contract 120 in conjunction with the adapter 300, the adapter 300 It stabilizes the value of service medium token (Medium of Exchange, MoE), which is a cryptocurrency used to provide services. The token contract 120 is also implemented as a adapter that operates independently in the blockchain system 100 without server intervention.

In order to use the adapter 300, the user has to pay a token as a price for performing the service provided by the adapter 300, so that the user is required to pay the token. of Exchange (MoE) token. For example, in a blockchain platform such as Ethereum, the adapter 300 may be distributed to the blockchain system while issuing a token, and the user may purchase a service agent token for using the adapter 300 to purchase a service adapter token. 300).

The token contract 120 stabilizes the value of the service agent token when the user using the adapter 100 is provided with the service through the adapter 100 using the service agent token.

Next, with reference to Figures 4 to 6, it will be described in detail a method for ensuring the value stability of the cryptocurrency by the token contract 120, that is, the service medium token.

4 is a view for conceptually explaining the overall operation of the first embodiment of the present invention.

First, the first embodiment of the present invention is based on the premise that a service medium token and a governance token are separately issued when the adapter 300 is distributed. Here, the service agent token refers to a token which is a cryptocurrency paid by a user to receive a service using the adapter 300 as described above, and the control token is a service agent token used for distributing the adapter 300. Tokens that have the right to receive. In the first embodiment of the present invention, as described below, in order to maintain the price stability of the service medium token, the service medium token may be additionally issued or repurchased in the market, and it may be determined that the service medium token is additionally issued. At this time, a token having a right to be distributed is called a dominant token, and a user holding such a dominant token is called a dominant token holder 500.

4 illustrates that the governing token and the service agent token are issued separately, and the service agent token adjusts the value of the service agent token so that it always corresponds to the same amount of service provision provided by the adapter 300. It features.

In general, the adapter 300 has a problem in that it will have to suffer chronic deflation as a competitive service emerges or the demand of the market changes over time. Because it is maintained, it is impossible to find a way to buy back the service medium token in the market, and thus it is impossible to prevent the value of the service medium token from falling. In this embodiment, each service medium token is incinerated whenever the adapter 300 performs the service. This will gradually reduce the volume of service vehicle tokens, thereby allowing inflation to continue in the long run to preserve the value of the governing tokens.

Referring to FIG. 4, a user uses a service provided by the adapter 300 by transmitting a transaction to the adapter contract 110 using the service agent token through the user system 200.

The token contract 120 incinerates some of the service medium tokens used when the adapter contract 110 performs a transaction for using the adapter 300, evaluates the average payment amount per unit service of the adapter 300, and evaluates the result. Adjust the value of the service medium token accordingly. Adjusting the value of the service medium token may be achieved by increasing or decreasing the token supply if the average payment per unit service is lower or higher than a predetermined criterion.

Increasing the token supply means issuing additional service agent tokens, and as described above, the additionally issued service agent tokens are transferred to the account of the controlling token holder 500.

Reducing the token supply may be achieved by issuing a controlling token or bond through the exchange 400 to purchase a service agent token or sell by auction.

Meanwhile, the exchange 400 refers to a market for trading service medium tokens and other cryptocurrencies, and the user 200 may buy or sell the service medium tokens through the exchange 400.

5 is a flowchart illustrating a method according to a first embodiment of the present invention using a token contract 120.

Referring to FIG. 5, first, a user generates a DAP transaction, which is a transaction for using a service provided by the DAP 300, through the user system 200 and transmits the generated DAP transaction to the blockchain system 100 (S100).

Here, the DAP transaction is generated through the DAP user interface 210 of the user system 200 and transmitted to one of the nodes of the blockchain system 100. The DAP transaction includes a sum (amount), a DAP contract address, and DAP contract data of a service medium token used in the blockchain system 100 to perform a service provided by the DAP 300, as is known in the art. In addition, it may include information necessary for other transactions such as signature information of the user, gas for performing the transaction, nonce and the like.

The node of the blockchain system 100 that receives the DAP transaction executes the DAP contract 110 corresponding to the DAP transaction based on the address of the DAP contract 110 included in the DAP transaction (S110). As described above, the dip contract 110 may be performed by the virtual machine 23.

When the adapter contract 110 is executed, the adapter contract 110 transmits a token transaction to the token contract 120 (S130). The token transaction is a transaction for incineration of a portion from the service agent token that the adapter 300 is paid from the user by the result of the execution of the adapter contract 110 when the token contract 120 is executed. Here, the token transaction includes the amount (price) of the service medium token, the token contract address, the token contract data, and may include other necessary data as described above.

The token contract 120 is also a smart contract, which can be executed by the virtual machine 23 of any one of the nodes included in the blockchain system 100, and by the execution of the adapter contract 110 by the execution of the token contract. A part of the service medium token received by the adapter 300 from the user is burned (S130).

Herein, the incineration of a part means that the adapter 300 destroys a predetermined amount from the amount of the service medium token received, for example. For example, when the service medium token paid by the adapter 300 is 100 for the performance of the service, it means that it destroys 0.1 and leaves a difference of 99.9.

At this time, the method of incinerating a part may use a method of incineration by a predetermined amount or incineration by a predetermined ratio.

In addition, it is possible to incinerate the amount of the determined amount by dynamically determining the amount to be incinerated each time without using a predetermined fixed value.

After the token contract 120 incinerates the service medium token, the remaining difference information is updated to the address of the adapter contract 110, and the incineration result message including the difference information is transmitted to the adapter contract 110 (S140). The contract 110 executes the service of the adapter 300 requested by the user through the user system 200 (S150), and when the execution is completed, transmits the result to the user system 200 (S160).

Meanwhile, the token contract 120 evaluates the average payment amount of the service medium tokens that the users pay on average for the unit service provided to the adapter 300 while performing the steps S100 to S160 (S170). ), The value of the service medium token can be adjusted accordingly. Since the code for performing this process is included in the token contract 120 in advance, the corresponding code may be automatically executed by the virtual machine 23. Evaluating the average payment amount may be made each time the token contract 120 is performed or may be made at regular intervals.

As a result of the average payment evaluation, if the average payment per unit service is less than 1-α, it means that the value of the service medium token is high, which means that the value of the service medium token is adjusted (lower) by increasing the supply of the service medium token. Therefore, in this case, the token contract 120 issues a new service agent token and supplies it to the controlling token holder 500 (S180). Here, α is a value in the range of 0 to 1, and is a value which can be adjusted as necessary. As described above, this may be automatically performed by the virtual machine 23 of the nodes 10 to 60 by code included to perform an operation corresponding to the token contract 120.

On the other hand, if the average payment amount is greater than 1 + α as a result of the average payment evaluation, it means that the value of the service medium token is low, so that the value of the service medium token is adjusted (by increasing the value of the service medium token). ) do. Thus, in this case, the token contract 120 either issues a new governing token or bonds to the service media tokens to buy the service media tokens from the user via the exchange 400 and then incinerate them. Reduce the supply amount of (S190).

The purchase through the exchange 400 and the collection by the issuance of the token are performed by the operation of the token contract 120, and the token contract 120 is sent to the exchange 400 by sending a buy signal or a bond issuing signal with a higher amount than the market price. It may be automatically performed by the virtual machine 23 of the nodes 10 to 60 by the code included to perform the operation corresponding to).

Meanwhile, the token contract 120 may adjust the incineration amount or the incineration rate by evaluating the average payment amount per unit service (S200). For example, if the average payment per unit service is less than 1-β, it means that the value of the service medium token is high, so that the supply amount of the service medium token can be increased by reducing the incineration amount or the incineration rate. If the average payment per unit service is greater than 1 + β, it means that the value of the service medium token is low, so that the supply amount of the service medium token can be reduced by increasing the incineration amount or the incineration rate. Here, β is also a value in the range of 0 to 1, which can be adjusted as necessary. This operation may also be automatically performed by the virtual machine 23 of the nodes 10 to 60 by the code included to perform the operation corresponding to the token contract 120 as described above.

According to this method, the governing token and the service agent token are issued separately, and the value of the service agent token can be adjusted so that the service agent token corresponds to the same amount of service provision provided by the adapter 300 at all times.

In addition, even when the value of the service medium token increases excessively, it is possible to stabilize the value of the service medium token by using the method described above, thereby preventing the value of the service medium token, which is a cryptocurrency as a whole, from rapidly rising or falling. have.

6 is a flowchart illustrating a method according to another embodiment of the present invention using a token contract 120.

FIG. 6 is basically the same as the embodiment of FIG. 5, but instead of incineration of the service agent token, whenever a token contract is executed (S300), a fee is distributed to the controlling token holder 500 (S310). There is a difference.

In this case, the fee refers to, for example, the amount of the service medium token corresponding to the amount of the service medium token or the corresponding service medium token corresponding to the deducted amount by subtracting a predetermined amount from the amount of the service medium token paid by the adapter 300, for example. do. For example, when the service medium token paid by the adapter 300 is 100, a subtraction of 0.1 and a service medium token corresponding to 0.1 or a corresponding control token to the controlling token holders 500 are performed. Means to dispense. In this case, the difference 99.9 of the service agent tokens is finally paid to the adapter 300.

Even in this case, the fee can be distributed by a predetermined amount or a predetermined ratio.

It is also possible to determine the amount of fees to be dynamically distributed each time without using a preset fixed value.

In addition, the embodiment of FIG. 6 performs the step S320 of adjusting the fee amount or ratio instead of adjusting the incineration amount / ratio of the service medium token (S200). Since similar to the process of adjusting the incineration solution / ratio in Figure 4, a detailed description thereof will be omitted.

The embodiment of FIG. 6 differs in that the fee is provided to the controlling token holder instead of burning the service medium token, but here the service that the adapter 300 is paid from the user to provide the fee to the controlling token holder. Since it subtracts some from the amount of the mediator token, this can actually mean the same as burning the mediator token.

In addition, in the embodiment of FIG. 6, a fee may be differentially paid to the controlling token holder, in which a special lease agreement is established with the existing controlling token holder in advance, instead of issuing a new controlling token when a service medium token needs to be purchased in the market. It is a method of renting a dominant token from an existing dominant token holder who has a lease agreement and using it to buy service tokens, and pays a higher fee only to the dominant token holder who lent the dominant token in return. Here, the fee payment can be differentiated according to the length of the lease agreement. This may also be performed by the token contract 120.

In the above, the preferred embodiment according to the present invention has been described, but the present invention is not limited to the above embodiment, and various modifications and changes may be made, of course.

For example, in the above embodiment, the function of the DAP is defined to keep the value of the service medium token equal to the common currency used in the market such as US dollar or Korean won, so that the service medium token can be used as a substitute for general purpose fiat money. You can also

That is, the unit service provided by the adapter according to the execution of the token contract is defined as transmitting the value of the legal currency preset per service medium token, and the unit service provided by the adapter by the execution of the token contract. It is possible to evaluate whether the average payment amount of the service medium token corresponds to the value of a predetermined legal currency, and adjust the value of the service medium token according to the evaluation result.

In this case, each time at least one node included in the blockchain system 100 performs a token contract, the value of the service medium token is adjusted to correspond to the value of the legal currency which has previously set the value of the service medium token. do. For example, define 1 unit of service medium token to correspond to the value of US $ 1, and if the user transmits the service medium token to another user by Dab, the unit service provided by Dap by the execution of the token contract It is possible to evaluate whether the average payment of the service medium token for the service medium corresponds to the value of a predetermined legal currency, that is, 1 unit of the service medium token corresponds to US $ 1, and adjust the value of the service medium token according to the evaluation result. have. The adjustment of the value of the service agent token, as in the embodiment described above, issuing the service agent token and providing it to the controlling token holder, issuing a new governance token, or issuing a bond for the service agent token in the marketplace.
