On each of the plurality of blocks included in the blockchain, transaction information generated for a predetermined time (block generation time) and verified by the node may be included. In addition, after verification of the node, information about a block connected to the blockchain may be propagated to nodes in the blockchain network 100.

Blocks connected to the blockchain may be generated based on mining, and various mining methods may be used such as proof of work (POW), proof of stake (POS), and deleted proof of stake (DPOS). The block is mined including the information of the previous block, and this mining scheme can prevent modulation on the transaction information recorded on the block.

Each block of the blockchain contains information about the movement of cryptocurrency on the blockchain, programming code (or blockchain code) to perform a specific algorithm based on the blockchain, such as a smart contract. It may include.

The nodes constituting the blockchain network 100 may include a stable coin service providing node 110, a stable coin service operating node 120, and a stable coin service using node 130. In addition, the nodes constituting the blockchain network 100 may include other nodes (eg, mining nodes, wallet nodes, etc.) having various other characteristics. Each node includes a communication unit and a processor, the communication unit is implemented for communication with the blockchain network and / or another node, and the processor may be operatively connected with the communication unit.

The blockchain network 100 is a network that acts as a platform that other blockchain-based services, such as the existing Ethereum blockchain network, can also be used for, or to operate only the stablecoin service according to an embodiment of the present invention. It may be a blockchain network.

The blockchain network 100 charges a transaction fee for a transaction using the first coin based on the blockchain code recorded on the block by the stable coin service providing node 110, and applies the transaction fee to the second coin. The wallet may be allocated to the wallet of the stable coin service operation node 120. The price of the first coin may have short-term price stability based on the second coin.

In addition, the blockchain network 100 transmits the voting information for determining the price of the first coin to the stable coin service operation node 120 staking the second coin based on the blockchain code, and the blockchain network 100 determines the price of the first coin by synthesizing the voting result information received from the stable coin service operation node 120 based on the block chain code, and the voting result information is based on the block chain code. Can be recorded on a predefined voting progress block.

Also, the blockchain network 100 collects information on the price of the first coin based on the blockchain code, determines the price volatility of the first coin, and the blockchain network 100 based on the blockchain code. The deposit type of the stability reserve fund is determined, the blockchain network 100 determines the distribution weight of the transaction fee for each deposit type according to the deposit type and / or price volatility based on the blockchain code, and the stability reserve fund It may be composed of a second coin staked by the table coin service operating device 120.

Also, the blockchain network 100 collects information on the price of the second coin based on the blockchain code, determines the price reduction rate of the second coin, and the blockchain network 100 targets the price based on the price reduction rate. It is possible to set the stock ratio and the range of change of the stock ratio.

In addition, the blockchain network 100 may change the transaction fee when the current stock ratio falls outside the range of the stock ratio change.

The above operations will be described in detail in the following embodiments of the present invention.

The stable coin service providing node 110 may be implemented to implement the stable coin service on the blockchain and to provide the stable coin service. For example, the stable coin service providing node 110 may store a smart contract for the stable coin service on the blockchain through the Ethereum blockchain network. Transactions generated by the Stable Coin Service Operation Node 120 and the Stable Coin Service Use Node 130 are processed based on the uploaded smart contract to provide the Stable Coin Service disclosed in the following embodiments of the present invention. Can be.

The first coin (or first cryptocurrency) and the second coin (second cryptocurrency) may be defined on the blockchain by the stable coin service providing node 110. The first coin may be a stable coin, and the second coin may be a non-stable coin. The stable coin may have short-term price-stability based on the exchange value with fiat money, which is characterized by a price fluctuating only within the threshold range. Unlike traditional cryptocurrencies, Stable Coins can be coins designed to be pegged into legal currency. For example, the stable coin may be a coin that has fixed the exchange value of cryptocurrency in the legal currency for a predetermined time, such as 1USD = 1 first coin, thereby reducing the value volatility over time to the minimum range. Non-stable coins can be coins that have value volatility depending on supply and demand without fixing value.

The second coin may be a non-stable coin. The transaction fee incurred by the use of the first coin as a transaction may be provided as an incentive to the stable coin service operation node 120 staking the second coin. In addition, the stable coin service operation node 120 staking the second coin may provide a right to vote for the operation of the stable coin service. In addition, the second coin may be staked in a stability reserve fund and subsequently utilized to ensure the value stability of the first coin.

That is, the first coin is used for trading of goods and / or services online and / or offline as a stable coin, and the second coin shares revenue generated by the stable coin service as a non-stable coin, It can be staked in a stability stock fund and utilized to ensure the value stability of the first coin. In addition, the node staking the second coin may be assigned a voting right to have the right to operate the stable coin service in a decentralized manner based on the voting right.

The stable coin service providing node 110 may upload the blockchain code for the stable coin service on the blockchain, and provide the stablecoin service based on the blockchain code through the blockchain network that generates the blockchain. Can be.

The stable coin service providing node 110 may be a node of a foundation that develops and services a stable coin service. The stable coin service implemented on the blockchain by the stable coin service providing node 110 will be described in more detail below.

The stable coin service operating node 120 may be a device that determines the operation of the stable coin service and is staking the second coin. The stable coin service operation node 120 may also include a node that stakes a second coin among the nodes of the foundation that develops and services the stable coin service.

The device currently staking the second coin on the basis of a booker on the blockchain may be set to the stable coin service operation node 120. For example, the Stable Coin Service Operation Node 120 is triggered based on the conditions recorded on the blockchain to operate the Stable Coin Service by sending suggestions for Stable Coin Service operation, voting for the proposal as a transaction. can do.

In addition, the stable coin service operation node 120 may be provided with an incentive according to the second coin being staked based on a condition recorded on the blockchain. The first coin is used to trade goods / services as a stable coin, and the transaction fee according to the use of the first coin is provided to the stable coin service operation node 120 in consideration of the number of second coins being staked. Can be.

The stable coin service using node 130 may be a device that trades goods / services using the stable coin service based on the first coin. The first coin is a stable coin and can be utilized as a payment method of goods / services in the online / offline market. For example, consumers can purchase a product in an online shopping mall using the first coin. When the first coin is used for the purchase of goods / services, a transaction fee may be generated according to the purchase amount. The transaction fee is not only provided as an incentive to the stable coin service operation node 120 staking the second coin, but also changes according to a reserve ratio, which will be described later, to maintain the price stability of the first coin. Can be used.

2 is a conceptual diagram illustrating a method of purchasing goods and / or services using a stable coin according to an embodiment of the present invention.

In FIG. 2, a method of purchasing goods and / or services using a first coin, a second coin, and a first coin is disclosed.

Referring to FIG. 2, the stable coin service using node (consumer) 240 proceeds to pay for goods and / or services using the first coin 210, and the stable coin service using node (seller) ( 260 may receive the first coin 210.

When ten first coins 210 are required to purchase a product, the stable coin service using node (consumer) 240 sends the ten first coins on the blockchain to the stable coin service using node (seller) 260. Transaction on the blockchain) can occur on the blockchain. The ten first coins on the blockchain are transferred from the wallet of the stable coin service using node (consumer) 240 to the wallet of the stable coin service using node (seller) 260 and the first coin 210 in the block. Movement can be recorded. The stable coin service using node (consumer) 240 may receive the first coin 210 as a wallet of the stable coin service using node (consumer) 240 in various ways. For example, the first coin 210 may be exchanged with the fiat currency using an exchange, or the fiat currency may be directly converted into the first coin 210 on the online shopping mall.

A transaction fee 260 may be incurred in a transaction using the first coin 210, and the transaction fee 260 may be transferred to the wallet of the stable coin operating node staking the second coin 220. The transaction fee 260 may be changed based on a reserve ratio, which will be described later, rather than a fixed value. The change of the transaction fee according to the stock ratio is described later.

Stability stock fund (or wallet) 250 may be comprised of second coins 220 staked by a stable coin operating node. Based on the stability reserve fund 250, the first coin 210 may maintain price stability and serve as a stable coin. This will be described later in detail.

The narrow stability stock fund 250 consists of a second coin 250 staked by the stable coin operating node, and the broad stability stock fund 250 is staked by the stable coin operating node. It may be configured to include a transaction fee 260 provided as an incentive according to the staking of the second coin 250 as well as the second coin 250.

Hereinafter, for convenience of description, it is assumed that the stability reserve fund 250 is configured in a narrow sense, that is, when the second coin 220 is staked by the stable coin operating node. However, the stability reserve fund 250 has a broad meaning, that is, a transaction fee provided as an incentive according to the staking of the second coin 220 as well as the second coin 220 staked by the stable coin operating node ( 260 is also included in the scope of the present invention.

3 is a conceptual diagram illustrating a method of implementing a stable coin according to an embodiment of the present invention.

In FIG. 3, a method for implementing stable coin is disclosed.

Referring to FIG. 3, the value of the whole coins staked in a token economy disturbance fund (or wallet) that may be used for negative purposes to change the price of the stable coin to maintain the price stability of the stable coin. The total value of the coins staked in the stability stock fund 300 should be greater than.

For example, the token economy disturbance fund may include an attacker fund 310 that wants to change the price of the stable coin, and a transformer fund 320 that believes and devalues the value of the stable coin. The value of all coins staked in the Token Economy Disturbance Fund is the value of the coins staked in the attacker's fund (A _t ) and the value of the coins staked in the debiter fund that believes in the value of the stable coin (D _t ). It may include.

The value R _t 300 of the stability reserve fund may be the total value of the second coins staked by the stable coin operating node.

That is, if the value of the whole coins staked in the stability reserve fund (R _t )> Token Economy Disturbance Fund is the value of the whole coins staked in the fund (A _t + D _t ), the first possible possible by the token economy disturbance fund The fluctuation of the price of the coin may be stabilized by using the staked coins in the stability stock fund 300.

Specifically, in order to prevent inflation and deflation of stable coins, stable coins are set by setting the value (R _t ) of the whole coins staked in the stability reserve fund 300 to be greater than the value of the whole coins staked in the token economy disturbance fund. You can increase your trust in and trust the payment ability of the stablecoin service. In addition, based on the payment ability of the stability reserve fund 300, it is possible to limit price disturbances of stable coins such as speculation or soros attacks caused by token economy disturbance funds.

Since it is difficult to actually determine the value of the whole coins staked in the token economy disturbance fund, according to an embodiment of the present invention, the first value of the stable coin that is distributed in the market to the value of the whole coins staked in the token economy disturbance fund It can be assumed as the total value of the coin 350.

That is, the entire coins staked in the stability stock fund 300 in order to set the value (R _t ) of the whole coins staked in the stability reserve fund 300 to be greater than the value of all coins staked in the token economy disturbance fund. in which the value (R _t) can be designed to be larger than the total value of the coin is the first coin Stables (350) circulating in the market.

4 is a conceptual diagram illustrating a method of implementing a stable coin according to an embodiment of the present invention.

In FIG. 4, an element for determining the price of the stable coin and keeping the price of the stable coin stable is disclosed.

Referring to FIG. 4, the price of the first coin in the stable coin may be determined by a vote of the stable coin service operating node staking the second coin. The voting result may be recorded on the blockchain, and the price 410 of the first coin may be determined according to the voting result 400. The voting right of the stable coin service operation node may be determined according to the second coin staking ratio of the stable coin service operation node. For example, a stable coin service operation node having a relatively large number of second coins may have a relatively higher voting authority.

As described above, the price of the stable coin may be maintained based on the value (R _t ) of the whole coins staked in the stability reserve fund. The second coin has a fixed supply amount. The stable coin service operation node staking the second coin may be provided with a transaction fee generated in the transaction based on the first coin as a reward. The transaction fee 430 received as an incentive may change according to the volatility of the price of the second coin 420.

 The staking of the second coin in the stability reserve fund may limit price disturbances of stable coins, such as speculative or soros attacks caused by token economy disturbance funds.

In addition, according to an embodiment of the present invention, the first coin can operate as a stable coin by adjusting the supply amount of the first coin. Collecting the information on the first coin price 440, and if the current exchange rate of the first coin is lower than the reference exchange rate based on the set pegging price of the first coin, the second staked to the stability stock fund The coin can be used for incineration after purchasing the first coin in the open market. The exchange rate of the first coin may be set to be the reference exchange rate by reducing the issuance of the first coin.

For example, it may be assumed that the first coin is pegged to exchange 1 USD so that the USD and reference exchange ratio are set to 1: 1. As the supply of the first coin increases, the exchange rate between the first coin and the USD may change to 1: 0.8. In this case, the first coin released on the market is purchased by using the second coin staked in the stability stock fund based on the blockchain code, and then burned to set the exchange rate of the first coin and USD back to 1: 1. Can be.

On the contrary, when the current exchange rate of the first coin is higher than the reference exchange rate based on the set pegging price of the first coin, the first coin may be newly issued through mining. The finances secured by the issuance of the first coin may be used in a decentralized manner as determined by the stable coin service operation node holding the second coin.

For example, it may be assumed that the first coin is pegged to exchange with 1 USD so that the USD and reference exchange ratio is 1: 1. As the supply of the first coin is less than the demand, the exchange ratio between the first coin and the USD may change to 1: 1.5. In this case, the first coin can be additionally mined and supplied to the market, and the new coin is released to satisfy the new demand for the first coin, and the exchange rate between the first coin and the USD is 1: 1. Can be set.

Hereinafter, in an embodiment of the present invention, 1) a method of determining a stable coin value based on voting on a blockchain, 2) a method of limiting a stable coin value volatility based on coins staked in a stability reserve fund, and 3) stability A method of controlling the supply amount of the first coin by utilizing the coins staked in the stock fund to maintain a stable exchange rate of the first coin is specifically disclosed.

5 is a conceptual diagram illustrating a method of determining a price of a stable coin based on voting on a blockchain according to an embodiment of the present invention.

In FIG. 5, a method of performing a voting on a blockchain to determine a price of a first coin by a stable coin service operating node staking a second coin is disclosed.

Referring to FIG. 5, every specific block (eg, every nth block, where n is a natural number), the stable coin service operation node may perform a voting to determine the price of the first coin. Hereinafter, the block in which the voting for determining the price of the first coin is performed may be expressed by the term voting progress block. The voting process may be performed based on a blockchain code (or programming code) such as a smart contract set up in a particular block on the blockchain by the stable coin service providing node.

The blockchain code can trigger a voting procedure to determine the price of the first coin for a particular block (every nth block). For example, a particular block may be expressed in terms of voting progress block. An algorithm for voting on the blockchain code may be triggered by considering a mining time point for the voting progress block. In addition, voting information 510 for determining the price of the first coin before the voting progress block based on the blockchain code is transmitted to the stable coin service operation node 500 and the stable coin service operation node 500 Voting rights may be set.

For example, when generation of the immediately preceding block of the voting progress block is completed and mining of the voting progress block is started, the plurality of stable coin service operation nodes 500 vote to determine the price of the first coin. You can proceed. The voting result information 520 generated by each of the plurality of stable coin service operation nodes 500 may be recorded as a transaction on a block (eg, a voting progress block or another block after the voting progress block). The voting result information 520 may include price information of the first coin voting by the stable coin service operation node 500.

When the voting progress block is mined and connected to the blockchain, the voting result information 520 transmitted by the plurality of stable coin service operation nodes 500 and recorded on the block may be aggregated. The price of the first coin (or the exchange rate of the first coin) may be determined based on the aggregated voting result information.

By allowing voting to proceed only on the voting proceedings block, prior to the end of the voting (ie, before the end of mining for the voting proceedings block), each of the plurality of Stable Coin Service Operations Nodes 500 that are voters are different It is not known what 500 voted.

For example, based on the aggregated voting result information, a weighted median of the prices of the first coins voted by the plurality of stable coin service operation nodes 500 may determine the price of the first coins. Only a range of values may be used to determine the price of the first coin in consideration of a standard deviation among the plurality of pieces of voting result information 520 synthesized. In addition, a sufficient number of stable coin service operation nodes 500 may determine a reasonable price of the first coin through various reward policies and punishment policies.

The reference exchange rate may be newly calculated based on the price of the first coin determined based on the blockchain code, and the reference exchange rate may be reset. In addition, according to the new standard exchange rate, the stock rate may be reset to adjust the supply amount of the first coin and the transaction fee.

The plurality of stable coin service operation nodes 500 for staking the second coin may be incentive for the transaction fee of the first coin, and thus may have motivation to keep the value of the first coin stable. In addition, as the stake amount of the second coin that the stable coin service operation node 500 is staking is larger, more voting authority may be granted to lower price volatility of the first coin. Similar to the Bitcoin consensus process, a specific Stable Coin Service Operation Node 500 or a specific Stable Coin Service Operation Pool may be restricted from having more than 50% authority. In this way, the stable coin service may determine the price of the first coin in a decentralized manner.

6 is a flowchart illustrating a method of determining a price of a stable coin based on voting on a blockchain according to an embodiment of the present invention.

In FIG. 6, a method of determining a price of a first coin based on a voting procedure on the blockchain described above with reference to FIG. 5 is described as a flowchart illustrating an operation flow between a blockchain and configuration nodes constituting the blockchain.

Referring to FIG. 6, the stable coin providing node may upload the blockchain code onto the blockchain (step S600).

The blockchain code for proceeding with the voting procedure described above with reference to FIG. 5 may be uploaded to a specific block on the blockchain. The voting procedure, which will be described later, is triggered by the condition set by the blockchain code, and the voting result is synthesized to reset the price of the first coin.

The blockchain network may trigger the progress of the voting to determine the price of the first coin for each voting block according to the blockchain code (step S610).

The blockchain network may trigger a voting procedure for determining the price of the first coin every voting progress block (eg, every nth block) based on the blockchain code. According to the setting based on the blockchain code, an algorithm for voting on the blockchain code may be triggered by considering a mining time point for the voting progress block.

The blockchain network may transmit the voting information to the plurality of stable coin service operation nodes (step S620).

As an optional step, voting information on the previous block of the voting progress block may be sent to a plurality of stable coin service operations nodes to vote on. The blockchain network may determine a plurality of stable coin service operation nodes staking the second coin based on the distributed ledger on the blockchain, and transmit voting information to the plurality of coin operation service nodes. The transmission of voting information may be performed on the blockchain network, or may be performed based on a separate network other than the blockchain.

The blockchain network allocates voting authority to the plurality of coin coin service operation nodes and receives voting result information (step S630).

For example, when the generation of the immediately preceding block of the voting progress block is completed and the mining of the voting progress block is started, a plurality of stable coin service operation nodes having voting rights may vote to determine the price of the first coin. You can proceed. The voting result information generated by each of the plurality of stable coin service operation nodes may be recorded as a transaction on a block (eg, a voting progress block or another block after the voting progress block). The voting result information may include price information of the first coin voting by the stable coin service operation node.

The blockchain network determines the price of the first coin based on the voting result information (step S640).

When the voting progress block is mined and connected to the blockchain, the voting result information transmitted by the plurality of stable coin service operation nodes and recorded on the block may be aggregated. Voting result information may be aggregated based on the blockchain code to determine a price (or exchange rate of the first coin) of the first coin.

For example, the blockchain network may determine the price of the first coin by synthesizing the voting result information based on the blockchain code. In addition, the blockchain network may be reset the reference exchange rate based on the determined first coin price, the stock ratio is also reset according to the new reference exchange rate, the supply amount of the first coin can be adjusted, and the transaction fee may be adjusted.

The adjusted first coin price, reference exchange rate, stock ratio, and supply amount of the first coin, which are changed according to the first coin price, are recorded directly on the blockchain, or recorded as a hash value to be transparent. (transparently) can be made public.

7 is a conceptual diagram illustrating a stability stocking method according to an embodiment of the present invention.

In FIG. 7, a stability reserve method for ensuring price stability of stable coins is disclosed. In particular, a method is disclosed for adjusting the distribution ratio of transaction fees distributed to a stability stock fund to ensure price stability of stable coins. At least one operation disclosed in FIG. 7 may be triggered by a block code uploaded on a block by the stable coin serving node, and the arrangement of blocks on FIG. 7 may be arbitrary and start on the same block or another block. Operations may be performed.

Referring to FIG. 7, the reserve ratio may be set to be equal to or greater than a certain threshold for stability stockpiling. The reserve ratio is the ratio of the value of the second coin staked in the stability reserve fund to the value of the first coin released to the market (ie, the value of the coin staked in the stability reserve fund / the value of the first coin released in the market). Can be.

Stability reserve funds staking the second coin can be divided into two types. The first is a stability stock fund (hot deposit) 700, which may be available for withdrawal within a set time (eg, 24 hours) after withdrawal notice. The second is a stability reserve fund (cold deposit) 720 that is locked up for a set period (e.g., 100 days) so that withdrawals cannot be made during the set period and can be withdrawn immediately after the set period. have.

Incentives according to the transaction fee incurred in accordance with the trading of the first coin may be distributed by applying distribution weights according to the type of the stability reserve fund (hot deposit or cold deposit) and the amount of second coins stored in the stability reserve fund. The distribution weight may be determined based on the deposit ratio 730, which is the ratio of the stability reserve fund (hot deposit) 700 and the stability reserve fund (cold deposit) 720, and the price volatility 740 of the first coin.

First, a method of changing the distribution weight 750 based on the ratio of the stability reserve fund (cold deposit) 720 and the stability reserve fund (hot deposit) 700 (hereinafter, the deposit ratio 730) is disclosed.

The stability reserve fund (cold deposit) 720 may have a relatively high distribution weight 750 since it contributes more to the price stability of the first coin than the stability reserve fund (hot deposit) 700.

Also, the larger the value of the stable reserve fund (cold deposit) / stable reserve fund (hot deposit) (i.e., deposit ratio 730), the greater the stability based on the reference distribution weight of the stable reserve fund (cold deposit) 720. A relatively low distribution weight 750 may be given to the reserve fund (cold deposit) 720. That is, since there are many stability reserve funds (cold deposit) 720, the stability reserve is stable, and thus, a relatively low distribution weight (750) is based on the reference distribution weight (default value) of the stability reserve fund (cold deposit) 720. ) Can be set.

Conversely, the smaller the value of the stability reserve fund (cold deposit) / stable reserve fund (hot deposit) (i.e., deposit ratio 730), the more relative to the reference distribution weight of the stability reserve fund (cold deposit) 720. A relatively high distribution weighting 750 can be given to the stability reserve fund (cold deposit) 720. That is, stability stockpiling cannot be performed stably in a situation where the stability stock fund (cold deposit) 720 is small. Accordingly, a distribution weight 750 that is relatively higher than a reference distribution weight of the stability reserve fund (cold deposit) 720 may be given to give more incentive to the stability reserve fund (cold deposit) 720.

Next, a method of changing the distribution weight 750 based on the price volatility of the first coin is disclosed.

Basically, the first distribution weight of the stability reserve fund (cold deposit) 720 may be set to be greater than the second distribution weight of the stability reserve fund (hot deposit) 700, but if the price volatility of the first coin becomes large, By setting the value of the first distribution weight / second distribution weight to a larger value, the Stable Coin Service Operation Node, which stakes the second coin, will induce the second coin to stake into the stability reserve fund (cold deposit) 720. Can be.

In this way, when the current exchange rate of the first coin is lower than the base exchange rate based on the set pegging price of the first coin, the first coin is purchased on the open market by borrowing the second coin of the second stability reserve fund. After the incineration, the reference exchange rate of the first coin may be re-established.

8 is a flowchart illustrating a stability stocking method according to an embodiment of the present invention.

In FIG. 8, a flowchart for adjusting the distribution ratio of transaction fees distributed to the stability reserve fund described above in FIG. 7 to ensure price stability of stable coins is disclosed as a flowchart.

Referring to FIG. 8, the deposit type of the second coin constituting the stability reserve fund on the blockchain network is determined (step S800).

The stable coin service operating node staking the second coin determines whether to stake the second coin using hot deposit or cold deposit and the determined result may be recorded on the blockchain. One Stable Coin Service Operation Node may stake some of all coins staking into hot deposits and the rest into cold deposits.

The block chain network may determine whether the second coin staked on the hot deposit or the cold deposit is staked based on the record on the block.

The blockchain network may determine the ratio of the stability reserve fund (hot deposit) and the stability reserve fund (cold deposit) (step S810).

The blockchain network can determine the ratio between the current stability reserve fund (hot deposit) and the stability reserve fund (cold deposit) based on the collected information.

The blockchain network may determine the price volatility of the first coin (step S820).

The blockchain network may collect information about the price of the first coin. For example, at least one exchange and at least one online market, information about the price of the first coin may be periodically collected and recorded on the block. The price volatility of the first coin may be determined based on the price information of the first coin recorded on the block.

The blockchain network may determine a distribution weight based on the ratio of the stability reserve fund (hot deposit) and the stability reserve fund (cold deposit) and the price volatility of the first coin (step S830).

The blockchain network may determine a distribution weight based on the ratio of the stability reserve fund (hot deposit) and the stability reserve fund (cold deposit) and the price volatility of the first coin according to the blockchain code.

The stability reserve fund (cold deposit) may have a relatively high distribution weight because it contributes more to the price stability of the first coin than the stability reserve fund (hot deposit).

In addition, as described above, the blockchain network is based on the blockchain code, and the stability reserve fund (hot deposit) and the stability reserve fund (cold deposit), respectively, according to the ratio of the stability reserve fund (hot deposit) and the stability reserve fund (cold deposit). The distribution weight for determining the transaction fee to be distributed can be changed.

In addition, the blockchain network changes the distribution weight to determine the transaction fee distributed to each of the stable reserve fund (hot deposit) and the stable reserve fund (cold deposit) based on the blockchain code's price volatility. You can.

The blockchain network may distribute the transaction fee to the stable coin operating node (step S840).

The blockchain network may distribute the transaction fee generated through the transaction to the stable coin operating node by applying the determined distribution weight.

9 is a conceptual diagram illustrating a method of setting a stocking ratio for stability stockpiling according to an embodiment of the present invention.

In FIG. 9, a method for maintaining a price stability of a first coin by setting a target stock ratio and a stock change ratio range is disclosed. At least one operation disclosed in FIG. 9 may be triggered by a block code uploaded on a block by the stable coin serving node, and the arrangement of blocks on FIG. 9 is arbitrary and may be initiated on the same block or another block. Operations may be performed.

Referring to FIG. 9, a target stock ratio 900 and a stock range changeable range 920 may be set according to a blockchain code uploaded on the blockchain.

As mentioned above, the stock ratio 900 may be the value of the second coin staked in the stability stock fund / the value of the first coin unwrapped in the market.

The target stock rate may be a target stock rate and may vary depending on price volatility of the second coin.

The reserve ratio changeable range may be set to 1 <r _min <r * <r _max . Here, r _min may be set to a value greater than 1 (eg, 1.2) as a minimum stock ratio at which the stock ratio should be satisfied at a minimum. The stockpile ratio must be greater than at least 1, but you can set a separate minimum stockpile ratio so that the stockpile ratio is greater than the minimum stockpile ratio.

r * may be a target stock ratio as the target stock ratio 920. The target reserve ratio 920 may be determined based on the minimum reserve ratio and / or price volatility of the second coin. For example, target stock ratio 920 may be defined as r * = r _min / (1-d). 'd' may be the maximum price reduction rate 900 of the second coin that occurred over a period of time (eg, 100 days). For example, if the second coin has had a 50% price drop over a period of time, then d = 1/2 and r * may be set to 2r _min .

r _max is the maximum value of the reserve ratio and may be the maximum reserve ratio. For example, r _max may be defined as 2r * -r _min . When r _max is defined as 2r * -r _min , the average value of r _max and r _min may be r *.

That is, the stock ratio changeable range 940 may be set in consideration of the variability of the second coin.

Information on price fluctuations of the second coin is recorded in the block on the blockchain, and based on the price volatility of the second coin, the blockchain network sets the target stock ratio 920 and the changeable range of the stock ratio 940. You can decide.

When there is a large fluctuation such as a large drop in the price of the second coin, the target target stock ratio 920 becomes large, and the changeable range 940 of the stock ratio may be set to be relatively wide. On the contrary, when there is no change in the price of the second coin, the changeable range 940 of the stock ratio may be relatively reduced.

10 is a flowchart illustrating a method of setting a stock ratio for stockpiling stability according to an embodiment of the present invention.

In FIG. 10, a method for maintaining the price stability of the first coin by setting the target reserve ratio and the reserve ratio changeable range disclosed in FIG. 9 is disclosed as a flowchart.

Referring to FIG. 10, the blockchain network may collect price information of the second coin and record it on the block (step S1000).

The blockchain network may periodically collect price information of the second coin based on the blockchain code and record it on the block. For example, the price information of the second coin may be transmitted as transaction information and recorded on the block based on the exchange API.

The blockchain network may determine the target stockpile ratio and the stockpile ratio changeable range based on the price information of the second coin (step S1010).

The blockchain network may use the block code and the input price information of the second coin to determine a target stockpile ratio and a stockpile ratio changeable range. The target stock ratio and the stockpile ratio changeable range may be determined through the above-described procedure in FIG. 9.

The blockchain network may record the determined target reserve ratio and reserve ratio changeable range on the block, and determine an additional output value (eg, a transaction fee) in consideration of the target reserve ratio and reserve ratio changeable range (step S1020). ).

The method for changing the transaction fee in consideration of the target stock ratio and the stockpile ratio changeable range will be described later.

11 is a conceptual diagram illustrating a method of adjusting a transaction fee for stockpiling stability according to an embodiment of the present invention.

In FIG. 11, a method for adjusting a transaction fee is disclosed when leaving a changeable range of a stock rate. At least one operation disclosed in FIG. 11 may be triggered by a block code uploaded on a block by the stable coin serving node, and the arrangement of blocks on FIG. 11 may be arbitrary and start on the same block or another block. Operations may be performed.

Referring to FIG. 11, a transaction fee 1100 may be determined in consideration of a current stock ratio according to a blockchain code uploaded on a blockchain by a stable coin service providing node.

If the stock ratio is less than r _min , the transaction fee 1100 may increase. When the transaction fee 1100 increases, the stable coin service operating node staking the second coin to receive incentives according to the transaction fee 1100 may increase relatively, and the reserve ratio may be greater than r _min. Can be.

In addition, since the increase in the transaction fee 1100 means an increase in revenue of the stable coin service operation node staking the second coin, the price of the second coin may be increased, and the price increase of the second coin is also stored in the stock ratio. Can be increased.

Conversely, if the reserve ratio is greater than r _max , the transaction fee 1100 may be reduced. When the stable coin economy according to the embodiment of the present invention continues to grow, the reserve ratio may be greater than r _max . When the transaction fee 1100 is reduced, the stable coin service operating node staking the second coin to receive incentives according to the transaction fee 1100 may be relatively reduced, and the reserve ratio is less than r _max. You can lose.

In addition, the decrease in the transaction fee 1100 means a decrease in profits of the stable coin service operation node staking the second coin, so that the price of the second coin may drop, and the decrease in the price of the second coin reduces the reserve ratio. Can be reduced.

According to an embodiment of the present invention, the blockchain network may be applied by changing the transaction fee 1100 when the stock ratio is reduced to r _min or less based on the blockchain code. The changing transaction fee f 'may be m * f, which is the product of the previous fee f times m. Here, m = r * / r _min may be the target stockpile ratio / minimum stockpile ratio.

In addition, the newly set transaction fee 1100 may be continuously maintained until the supply of the first coin has a net growth percent of at least m. The supply of the first coin having a net growth percent of at least m may serve as a milestone 1120 to trigger a change in transaction fee.

For example, if the transaction fee 1100 is increased by 50%, at least 50% increase in the supply of the first coin may be set to the milestone 1120. Accordingly, the transaction fee 1100 may be maintained until the supply of the first coin is increased by at least 50%, and the transaction fee 1100 may be changed when the supply of the first coin is increased by 50%.

When the milestone 1120 is achieved, the transaction fee 1100 may be reduced by a set percentage (eg, 0.02) every first set period (eg, 10 days). In exceptional cases, when the stock ratio exceeds r _max , the transaction fee may be reduced every second setting period (eg, 24 hours).

If the current reserve ratio is outside the reserve ratio changeable range, the transaction fee change algorithm above may be triggered on the blockchain to adjust the transaction fee 1100 to approach the target reserve ratio.

The change size of the transaction fee 1100 may be determined according to the size of the maximum value fall of the second coin. As the value of the second coin decreases, the transaction fee 1100 may change more.

If the depreciation of the second coin occurs continuously and the newly set transaction fee 1100 as in the algorithm described above continues to hold until the supply of the first coin has a net growth percent of at least m. If it does not reflect a continuing decline in value, the stock ratio cannot quickly come within the range of change in the stock ratio.

Therefore, when the price drop of the second coin exceeds the threshold range, even if the milestone 1120 described above is not satisfied, the set transaction fee 1100 may be fixed only for a set time and may be further changed thereafter. For example, if the value fall of the second coin exceeds the threshold range, the transaction fee 1100 is fixed for 24 hours, and the transaction fee 1100 is changed in consideration of the price change of the second coin after 24 hours. Can be. In this way, even when the second coin changes drastically, the stock ratio can quickly enter the changeable range of the stock ratio.

According to an embodiment of the present invention, the value of the second coin may be determined as follows.

<Equation 1>

Where R _t is the value of the second coin stored, T _t is the supply amount of the first coin, V _t is the circulation rate of the first coin, and m _t is the price-to-earning ratio (P / E) It may be a relative ratio of the price of the second coin to the incentive obtainable per second coin.

May be a profit that can be obtained based on the transaction fee 1100 for one year.

12 is a flowchart illustrating a method of adjusting transaction fees for stability stocking according to an embodiment of the present invention.

In FIG. 12, a method for adjusting the transaction fee described above in FIG. 11 is disclosed.

Referring to FIG. 12, information on a reserve ratio may be set on a blockchain and a current stock ratio may be determined (step S1200).

Based on the blockchain code, current stock ratio determination information for determining the current stock ratio may be collected. In detail, on the blockchain network based on the blockchain code, information about 1) a second coin staked in a stability stock fund and 2) a first coin released to the market may be collected.

The blockchain network may determine the value of the second coin staked in the stability stock fund based on the second coin information staked in the collected stability stock fund. In addition, the blockchain network may determine the value of the first coin released to the market based on the blockchain code.

The blockchain network can determine the current reserve ratio based on the value of the second coin staked in the stability stock fund and the value of the first coin released on the market.

The blockchain network determines the transaction fee based on the current stock ratio, the target stock ratio, and the possible change in the stock ratio (step S1210).

The target stockpile ratio and the stockpile ratio changeable range may be calculated in the above-described procedures of FIGS. 9 and 10.

As disclosed in FIG. 11, the blockchain network may increase the transaction fee when the current stock ratio is smaller than the minimum stock ratio r _min based on the blockchain code. In addition, the newly set transaction fee may be continuously maintained until the supply of the first coin has at least a certain net growth percent.

Further, if a set milestone is achieved, the transaction fee may be reduced by a set percentage (eg 0.02) every first set period (eg 10 days). In exceptional cases, when the stock ratio exceeds r _max , the transaction fee may be reduced every second setting period (eg, 24 hours).

In exceptional cases, if the blockchain network tracks the price volatility of the second coin, and the value of the second coin continues to fall above the threshold, additional transaction fees may be adjusted even before milestone achievement.

13 is a conceptual diagram illustrating a method for implementing stable coin according to an embodiment of the present invention.

In FIG. 13, a method for controlling the supply amount of the first coin by utilizing the second coins staked in the stability stock fund is disclosed so that the first coin operates as a stable coin. At least one operation disclosed in FIG. 13 may be triggered by a block code uploaded on a block by the stable coin serving node, and the arrangement of blocks on FIG. 13 may be arbitrary and start on the same block or another block. Operations may be performed.

Referring to FIG. 13, when the price of the first coin is lower than the pegged price, the second coin may be borrowed from the stability stock fund to purchase and incinerate the first coin in the open market. Purchasing and incineration of the first coin may reduce the amount of the first coin circulated in the market to prevent the price of the first coin from falling and the reserve ratio may be changed within a possible change ratio of the reserve ratio.

On the contrary, when the price of the first coin is higher than the pegged price, the first coin may be further mined on the blockchain. When the newly mined first coin is supplied to the market, a mining fund according to the sale of the first coin may be formed.

The use of mining funds can be agreed in the following manner.

A device that is staking a predetermined number (eg, 1000) or more of the second coins among the stable coin service operating nodes staking the second coin may be set as the representative stable coin service operating node. The representative Stable Coin Service Operation Node can propose a usage for the mining fund and vote on the usage proposal. Voting authority of the representative stable coin service operation node may be set relatively different according to the number of stakings of the second coin. Each representative stable coin service operation node may be assigned an identifier. The usage proposal is a single unit of data (e.g. a tuple), requesting a funding size for the usage proposal, a target wallet address, an identifier of a representative Stable Coin service operational node, an address related to the proposal (e.g., And a www url (uniform resource locator) link that contains a description.

A meeting for n blocks may be set up and proceeded to determine the use of the mining fund. The meeting for n blocks can determine the use of additional mining funds.

When the exchange rate of the first coin increases (e.g., when the exchange rate of the first coin and USD changes from 1: 1 to 1: 1.5), every set time (e.g. every 15 minutes) ( ) First coins may be issued, and the first coins issued may be sold on the open market and exchanged for another cryptocurrency (eg, Ethereum) to create a mining fund.

The mining fund may be used to pay back the cost of borrowing a second coin from a stability reserve fund if the price of the first coin first falls below the pegged price. Thereafter, the remaining mining funds may be stored in a separate mining fund wallet.

The meeting may be conducted periodically in units of n blocks to determine the use of the mining fund described above. For example, n blocks may be a period corresponding to one month. The representative Stable Coin Service Operation Node may proceed by meeting for the current n blocks for the use of cryptocurrencies stored in the mining fund wallet for the previous n blocks.

14 is a conceptual diagram illustrating a voting method according to an embodiment of the present invention.

In FIG. 14, a method is disclosed in which a representative stable coin service operating node votes on the use of cryptocurrencies stored in a mining fund wallet during a previous n blocks. At least one operation disclosed in FIG. 14 may be triggered by a block code uploaded on a block by the stable coin serving node, and the arrangement of blocks on FIG. 14 is arbitrary and may be initiated on the same block or another block. Operations may be performed.

Referring to FIG. 14, at the start of each n-block conference session, the stable coin service operation node may check the proposal / voting history of each representative stable coin service operation node. The representative Stable Coin Service Operations Node may declare a waiver for voting.

The representative Stable Coin Service Operations Node may proceed to register a usage proposal for a mining fund and / or vote on a usage proposal for a mining fund during an n-block meeting session. Voting can be cold / half.

Suggestions for use at the end of an n-block conference session may be stored in a queue, sorted sequentially according to the size of the voting balance (yes-no). If there is more opposition than yes and the voting balance is negative, it can be removed from the queue without being stored.

The ordered usage proposal may be dequeued and processed in first in first out (FIFO) order until the mining fund stored in the mining fund wallet is exhausted during the previous n-block meeting session.

For example, 100ETH exists in the mining fund wallet, and Suggestions 3 (50ETH required), Suggestion 1 (requires 30ETH), Suggestions 4 (requires 20ETH), and Suggestions 6 (requires 30ETH) depending on the voting balance. If present, Proposal 3 (requires 50ETH), Proposal 1 (requires 30ETH), Proposal 4 (requires 20ETH) in FIFO order, the remaining Proposition 6 is either not processed or proceeds to the next n-block conference session. Can be.

If the mining fund existing in the mining fund wallet remains to process all the usage proposals present in the queue, the remaining mining funds may be used for processing the usage proposal in the next meeting session.

The representative Stable Coin Service Operations Node that participated in the voting of the current meeting session may be provided with a portion of the transaction fee collected in the previous meeting session. The amount of compensation may be proportional to the staking size of the second coin. These rewards can increase the vote participation rate of the representative Stable Coin Service Operation Node.

According to an embodiment of the present invention, an additional method for stably maintaining the initial stable coin protocol may be used. In the early stable coin markets, rational valuations are difficult, and low trading volume and low cash flows can increase the volatility of stable coins.

Thus, in the embodiment of the present invention, some of the Stable Coin Service Operations Nodes (eg, Stable Coin Service Operations Nodes of the Stable Coin Service Foundation) are obtained through sales on the market of the first coin using voting rights. Mining funds can be used to stock fiat currency (eg fiat currency). This nominal currency reserve allows one to have a parity of 1: 1 between the stable coin economy and the nominal currency.

After the initial service operation, if a stable coin economy is mature, another decentralized application (dApp) may be grafted onto the stable coin economy. The incorporation of other dApps can expand the Stable Coin Economy and diversify the assets associated with the Stable Coin Economy. In this way, the Stable Coin Economy can be more robust to external shocks.

15 is a conceptual diagram illustrating a stable coin service method according to an embodiment of the present invention.

In FIG. 15, a method for a blockchain network to adjust a supply amount of a first coin is disclosed.

Referring to FIG. 15, the blockchain network may collect information on the first coin price and compare it with the pegged price (step S1500).

The blockchain network may collect information on the first coin price based on the blockchain code and compare it with the pegged price.

If the price of the first coin is lower than the pegged price, the blockchain network may borrow the second coin from the stability reserve fund to purchase and incinerate the first coin in the open market (step S1510).

The blockchain network may record the second coin information borrowed from the stability stock fund on the block, the purchase information of the first coin in the open market, and the first coin information incinerated.

If the price of the first coin is higher than the pegged price, the blockchain network may further mine the first coin on the blockchain (step S1520).

When the newly mined first coin is supplied to the market, a mining fund according to the sale of the first coin may be formed.

The blockchain network may pay back the second coin borrowed using the mining fund (step S1530).

The blockchain network may determine a representative stable coin service operating node (step S1540).

The blockchain network may receive a proposal to use the mining fund and proceed to vote (step S1550).

The representative Stable Coin Service Operation Node can propose a usage for the mining fund and vote on the usage proposal. Voting authority of the representative stable coin service operation node may be set relatively different according to the number of stakings of the second coin.

 The blockchain network may aggregate the voting results, record them on the block, and process them in a FIFO manner (step S1560).

The blockchain network may store the proposed usage proposals in a queue in a sequential order based on the size of the voting balance (yes-no) through n-block conference sessions. If there is more opposition than yes and the voting balance is negative, it can be removed from the queue without being stored.

The blockchain network can process the ordered usage proposals by dequeuing them in first in first out (FIFO) order until the mining funds stored in the mining fund wallet are exhausted during the previous n-block meeting session.

16 is a conceptual diagram illustrating a transaction fee providing method according to an embodiment of the present invention.

In FIG. 16, a method for increasing price stability of a first coin by adjusting a distribution timing for a transaction fee is disclosed.

Referring to FIG. 16, the transaction fee may be distributed to the stable coin service operation node. The transaction fee may not be directly distributed, but may be divided by setting a period and distributed to the stable coin service operation node.

For example, the average value of transaction fees generated in each of the 10 transaction fee calculation periods may be distributed to the stable coin service operation node.

Transaction fee calculation period may be divided by a specific time period, such as the _{V t, V t-9,} V t-8, V t-7, V t-6, V t-5, V t-4, V The average value of the transaction fees for which the previous 10 transaction fee calculation periods were calculated, such as _t-3, V _t, V _t-2, V _t-1, V _t (that is, [V _t-9 + V _t-8 + V _t-7 + V _t-6 + V _t-5 + V _t-4 + V _t-3 + V _t + V _t-2 + V _t-1 + V _t ) / 10] is _stable after V _t It may be provided to the coin service operation node.

In this case, in order to provide a transaction fee as an incentive, the number of divisions (in this case, ten sections) may be changed in consideration of the price volatility (or stock ratio) of the second coin.

For example, when the price of the second coin falls, if the transaction fee calculation period is reduced from 10 to 8, the recent transaction fee may be relatively reflected. In this way, the net present value of the second coin can be increased to prevent the price change of the second coin.

According to an embodiment of the present invention, as described above, the blockchain network may obtain information on the price and the stocking ratio of the second coin based on the blockchain code. The blockchain network may determine whether the transaction fee calculation period is increased or decreased in accordance with the change in the price and / reserve ratio of the second coin when the price and / reserve ratio of the second coin is less than the set threshold.

Even when a recession occurs through the division of the transaction fee calculation period, the transaction fee is normalized so that the stable coin service operation node may receive a transaction fee that does not significantly decrease even when the recession occurs.
