Smart Pairing Smart Pairing is a value protocol for Decentralized Finance (DeFi) and Central Finance of digital assetization that sets the value of DeFi as the basis for determining the value of central finance. Decentralized Finance is based on Cryptocurrency like Bitcoin and Ethereum, while Central Finance is based on national currencies such as USD and KRW. Investors in DeFi refer to people who buy Cryptocurrency such as Bitcoin and Ethereum, while DeFi refers to those who use Cryptocurrency as a means of trading and payment. Since Cryptocurrency such as Bitcoin and Ethereum, which are the basis of Decentralized Financing, are very important in determining the value of Cryptocurrency. It is a concept that can present accurate and transparent standard average price.

History

Smart Pairing was proposed by Russia cryptographers: Alensky, Uzbek cryptographers: Khalilov Valijon, Saidov Jamshid, and Korean cryptographers: Ha Woo Sung, An Ho Sub and Cho Kwang in 2019. In these implementations, the average price of the currency value of the CryptoCoin based on the currency of the central bank was implemented based on the blockchain.

Necessity

The credibility of CryptoCoin, the currency of the blockchain, is high because CryptoCoin's accurate and transparent value judgment determines its value only through trading (sell, buy) through the exchange. The birth of StableCoin, which chose CryptoCoin currency as the national currency due to the acceleration of distrust, is bringing even greater distrust. Currently, the currency of the StableCoin is a state-run digital currency and is not regulated by the law of the country. Currently, StableCoins are issued by companies and are not under the control of the laws of the country, so there are various risk factors such as trading and storage of StableCoins. We need a pair that can quote the average price of CryptoCoin with the value of StableCoin's activation.

Implementation

Smart Pairing could be formed through the concept of a pair that represents the value of currency between countries.

In addition, we applied VWAP and TWAP algorithms to determine the value of exchange rates.

There is two basic structures in Smart Paring.

Crypto Coin - A digital asset that represents Decentralized Finance Price value of CryptoCoin is based on “Volume Weighted Average Price” (VWAP) as the main concept and “Time Weighted Average Price” (TWAP) as a sub concept to create Average Price of value judgment.
Stable Coin - A digital asset that represents Central Finance Stable Coin creates the average price of the value judgment based on the (Country Weighted Average Price) as the main concept.

Smart Pairing presents the average price of CryptoCoin as a pair of the average price of Stable Coin as TWAP (Time Weighted Average Price) and the suggested average price of CryptoCoin VWAP and TWAP.

These suggested prices are contracted through smart contract. Smart Contract allows you to conduct transactions that you can trust without third parties.

StableCoin trading volume of TWAP

StableCoin trading volume of TWAP = ( Open Transaction Count + High Transaction Count+Low Transaction Count+Close Transaction Count) / 4

Open Transaction Count: Number of transactions initially traded
High Transaction Count: Number of trades highest in the market
Low Transaction Count: Number of trades lowest in the market
Close Transaction Count: Number of trades last in the market

StableCoin Profit

StableCoin trading volume of TWAP * StableCoin trading fee

CryptoCoin VWAP

CryptoCoin VWAP = (((High Price + Low Price +Close Price) / 3) * Volume) / Volume

High Price: Market Best Price
Low Price: Lowest Price in Market
Close Price: Market Last Price
Volume: Trading Volume

StableCoin TWAP

StableCoin TWAP = (Open Price + High Price + Low Price +Close Price) / 4

Open Price: Market First Price
High Price: Market Best Price
Low Price: Lowest Price in Market
Close Price: Market Last Price
Volume: Trading Volume

CryptoCoin Revenue

CryptoCoin trading volume TWAP * Crypto transaction fee

StableCoin Revenue TWAP

StableCoin Revenue TWAP = (SCR Open Price + SCR High Price + SCR Low Price + SRC Close Price) / 4

SCR Open Price: StableCoin Proceeds Initial Price
SCR High Price: StableCoin Revenue of Best Price
SCR Low Price: StableCoin Revenue of Lowest Price
SCR Close Price: StableCoin Revenue of Last Price
SCR Volume: StableCoin Revenue of Trading Volume

CryptoCoin and Smart Contract of StableCoin (Smart Pairing)

First Type - Publish CryptoCoin in the ratio of StableCoin / CryptoCoin Pair to the profit of StableCoin
Second Type - Publish StableCoin in the ratio of CryptoCoin /Stable Coin Pair to the profit of CryptoCoin
