Matching Exchange System Development | Blockchain Contract Trading System Development

Since the total amount of BTC is constant and has better divisibility than gold, the uncertainty of the international financial situation has strengthened the hedging properties of BTC, which has aroused more investors' trading and attention. The recognition and wide application of blockchain technology is also an important factor pushing up the price of BTC.
The digital asset trading platform is still the most mature system in the application of blockchain technology. Compared with currency applications, digital asset trading platforms can provide users with more services. It has derived a series of models that can make users more aware of the power of blockchain technology. For the current mainstream trading platform models, mainly over-the-counter transactions and currency-to-currency transactions. Of course, these two models have their own advantages.
Matching/Trading Engine, as the name suggests, is a software used to match transactions, which is widely used in finance, securities, cryptocurrency trading and other fields. The trading engine is responsible for managing all open orders (Open Orders) in the crypto asset market, and automatically execute transactions when a matching order pair (Trading Pair) is found.
The principle of currency matching transactions:
1. Matching transaction algorithm The core business module of the matching engine is the matching transaction algorithm. On the one hand, the task of the matching transaction algorithm is to complete the fair and reasonable arrangement and matching function of the orders placed by customers, and also to ensure the matching The matching business of different financial transaction systems such as the fairness, efficiency and scalability of the algorithm is different.
2. An important part of the order queue matching transaction is the buying and selling order. By matching the buying and selling orders, the transaction records are finally lined up; therefore, for the orders that cannot be matched immediately, there needs to be a buy queue and a sell queue to save the order, and the queue is in accordance with The principle of "price priority" and "time priority at the same price", the buying queue is arranged in the order of the commissioned price "from low to high", and the selling queue is arranged in the order of the commissioned price from "low to high"
The advantage of the distributed framework of the exchange is that the decoupling of different systems and modules is important, which reduces the dependency between various subsystems and sub-modules. Each module can be developed independently and deployed independently without interfering with each other, which is convenient for rapid development. Distributed structure such as locating faults is to split a complete system into independent subsystems according to business functions. In a distributed structure, each subsystem is called a "service". These subsystems can run independently in the web container, and communicate between them through RPC.
