DASH - cryptocurrency, seeking to replace traditional payment systems such as PayPal and Visa. The project was created by programmer Evan Duffield, who initially wanted to add anonymity to Bitcoin, but the community did not accept his idea. Then, in a few days in January 2014, he created a new cryptocurrency code, called DarkCoin (later named XCoin, and then DigitalCASH (DASH)).A key feature of this cryptocurrency is to provide cryptocurrency transactions with complete anonymity, this is achieved through the X11 algorithm, which collects 11 different cryptographic algorithms. DASH has a significantly fast network, which is a two-level system of miners (PoW algorithm) and masternode holders. The network is completely decentralized and so each participant with an open masternode can vote to change various parameters within the network.The team is actively developing and actively working not only on the development of the network, but also on the implementation of DASH in many services and institutions of the real world. This cryptocurrency is already used in many online stores around the world, there are also a number of partnerships with representatives of the financial sector, this has become possible due to the high speed of the network and a very low commission.
