The idea of cryptocurrency exchanges is not particularly new but the mechanism for 100 % secure e-trading with extra-fast execution of the contracts is still missing. The DLEX project has been created by a group of software developers and cryptocurrency experts. It is a cryptocurrency exchange with advanced features. The project has several functional features that may be easily omitted by the users. The key idea of the project is to create a unified Blockchain-based infrastructure that allows each user to carry out necessary trade operations using the system’s own web-interface. Security and high-speed operation of the system are guaranteed by the liquidity pool. In fact, the project combines the advantages of both decentralized and centralized Blockchain systems. The former offers security and anonymity while the latter provides high-speed execution of the contracts. How the DLEX Exchange Differs from the Lookalikes? The liquidity pool and orders are used in this project for the first time. Consequently, this decreases the time needed to process the operations. Their safety is ensured by the use of the traditional Blockchain methodology.
