The development technology of digital currency exchange is a decentralized consensus mechanism to maintain a complete,distributed and tamper proof ledger database.It enables participants in the blockchain to achieve a unified ledger system without establishing trust relationships.
什么是Web3？
Web3（或Web 3.0）是万维网当前形式的演进，后来被称为Web2。我们今天的互联网在很多方面都是高度集中的，在很大程度上由大公司控制。Web3为网络提供了另一种去中心化的愿景。一个由其用户统治并由加密货币和区块链技术驱动。
Web3也是一个总称，用于涵盖支持去中心化互联网框架的各种项目和技术。
1、 The development of digital currency exchange mainly includes the following four systems:
① Matchmaking engine
It is mainly about order matching. All orders bought and sold by the exchange need matching engines to trade. Its performance directly determines the user's trading experience.
② Blockchain wallet
The digital currency exchange system development itself and all digital currencies of users are stored in the blockchain wallet. Every asset transfer of users is an interactive behavior on the chain, which is completed by the wallet.
③ Transaction management
The function of this system stipulates the trading rules and records the trading data. It manages the rise and fall of the exchange, the K line and the trading data.
④ Account system
Each user will have his/her own account on the exchange, which includes the user's identity information, asset information, transaction information, etc. These information needs to be recorded and managed uniformly by the account system.
Among the above four systems, two are the top priorities of system construction, one is the matchmaking engine, and the other is the blockchain wallet.
The matchmaking engine is as important to the exchange as the heart of man. All trading activities of the exchange are completed by the matchmaking engine alone. The larger the exchange is, the larger the trading volume in seconds is. The more challenging the performance of the matchmaking engine is. If the performance is poor, the exchange may collapse at any time.
2、 What aspects should be paid attention to in the development of digital currency exchange system?
Security performance: The exchange is a place for digital currency trading, and its security is very important. During the development of the exchange, various hazards and hazard protection measures, such as anti black attack measures, need to be considered.
Efficiency: The performance of a digital currency exchange needs to be efficient, requiring real-time receipt. An exchange that cannot complete transactions as soon as possible will not only fail in terms of performance, but also bring users a very poor user experience. A large number of users will be lost.
Maintenance and expansion: the functions of the exchange are not single or fixed. There will be more and better functions in the future, not to mention in the future, if customers want to expand channels and increase business on the platform, they also need a flexible way to expand the system.
Functional diversification: The currency trading mode and OTC OTC trading mode are only two of a variety of trading modes, and different trading modes have their own functions and characteristics. It is also very important to choose a suitable transaction mode for development
3、 Introduction to the development of digital currency exchange system:
Support a variety of different currency pair trading venues: French currency trading, contract trading, leverage trading, etc.
It can provide the development of APP and PC.
Secure multi-layer encryption function, supporting digital virtual currencies publicly issued by all mainstream platforms and currency transactions issued by their own platforms.
Support C2C point-to-point transactions, OTC over-the-counter transactions and other forms of entry and exit.
Security issues: two-layer encryption of the platform and the underlying encryption technology of the blockchain to ensure data/encryption/storage, permissions and control,
System: high-performance matching engine; One to one or many to one low latency technology and million level concurrency. Isolate the sub control system and verify the private cloud (vpc).
Back end settings for customers, agents, merchants, wallet assets, transaction costs, etc
