In the current system design or application development, the central server is considered to realize all information exchange and data storage. But in the blockchain, by building a distributed structure system and open source protocols, all participants are allowed to participate in the recording and verification of data, and then sent to each node through distributed propagation, even if some nodes are attacked or damaged. It will not affect the integrity and information update of the entire database, which is equivalent to that each participating node is "self-centered."
The reason why the blockchain is attractive has its advantages, that is, the mechanism of distributed storage. The information records on each block in the blockchain are recorded by each computer participating in the bookkeeping, mainly node competition records.
The soul of the blockchain is to form an important consensus mechanism to ensure that nodes are willing to take the initiative to keep accounts. In addition to the above-mentioned core technologies, blockchain is also applied to mathematics, economics, etc.
All digital assets in the exchange will be recorded on the blockchain, which can be used as the user's asset certificate. The digital assets on the chain are cleared in real time for matching transactions, without suspension, and easy to reconcile
Three types of exchanges:
Legal currency-digital currency exchange
Currency exchange: digital currency versus digital currency
Contract Exchange (Futures Contracts and Perpetual Contracts)
What are the common development models in the blockchain exchange system platform?
(1) Introduction to price-limit trading mode:
Limit buy/sell means that the user sets the price and quantity of a buy/sell coin, generates an order, and the system will automatically best match the buy and sell orders in the market. Once the price set by the user is reached, the price priority time will be given priority The order is automatically executed.
(2) Introduction to currency trading mode:
The currency transaction is mainly for the transaction between virtual digital assets and virtual digital assets. One of the currencies is used as the unit to purchase other currencies. The currency transaction rules are also to complete the combined transaction according to the price priority time priority order.
(3) Introduction to quantitative trading mode:
Quantitative trading refers to the use of advanced mathematical models to replace human subjective judgments, and the use of computer technology to select multiple "high probability" events that can bring excess returns from huge historical data to formulate strategies, which greatly reduces investor sentiment The impact of volatility, to avoid making irrational investment decisions when the market is extremely enthusiastic or pessimistic.
(4) Introduction to market price trading mode:
Buying at market price means that the user sets a total amount and generates an order, which is matched from the beginning of the sale until the total amount is completed. Market selling means that the user sets the total number of coins to be sold, generates an order, and matches from the beginning of the purchase to the completion of the total number of coins transaction.
(5) Introduction to margin trading mode:
Leveraged trading is the use of small amounts of funds to invest several times the original amount. In order to expect to obtain a return rate of several times relative to the fluctuation of the investment target, or loss. Since the increase or decrease of the margin (the small amount of funds) does not move in proportion to the fluctuation ratio of the underlying asset, the risk is high.
