Description

Decentralized exchange system, trading method, equipment and storage medium
Technical Field
The invention belongs to the technical field of computers, and particularly relates to a decentralized exchange system, a trading method, equipment and a storage medium.
Background
The most prominent essential feature of blockchains is decentralization. At present, two decentralization exchange schemes exist on a block chain, one scheme is to provide liquidity in the form of an order book, and represents the exchanges such as Newdex, IDEX, DDEX, Radar Relay, EtherDelta and the like; one is to provide liquidity by way of an automated market (AMM) represented by Uniswap, Bancor, etc.
The order book contains a list of orders, called bids (bid), and orders, called ask (ask), called ask. The order book lists the number of tokens to be bid or ask at each price point. The highest bid (buy one) and lowest ask (sell one) are referred to as buy and sell one (top of the book). They mark the market mood as well as the bid and offer prices needed to obtain the order. The difference between the highest bid price and the lowest ask price is the spread (spread). For an exchange in order book mode, its scope of applicability is a well-liquidated market. The traditional stock market and the centralized digital currency trading market adopt the order book mode. However, for a less mobile market, many problems arise with the exchange in order book mode. At the time of trading, an order is completed only if the bid and ask match, and the market will not be able to trade if the market highest bid is still below the lowest ask. Therefore, for the market with insufficient liquidity, the order book trading scheme has the problem that the trading success rate is low when the spread price is too large.
The automatic marketing scheme does not adopt an order book mode, but adopts a coin exchange algorithm, namely, the exchange between two or more coins is realized according to a certain rule or exchange rate. The essence of the automated market (AMM) is a commodity exchange or coin exchange, the transaction mode gives users great freedom, users can randomly select coins existing in two exchanges to exchange coins based on certain rules, the AMM exchanges on the market at present are gradually touted by the users, but with the gradual rise of transaction amount, the transaction amount is limited by the TPS of one layer of network, and limited by the TPS of one layer of network, the transaction fee may become very high, which is very unfriendly for the exchanges.
