Dash was founded by software developers Evan Duffield and Kyle Hagan. The project was originally called XCoin, changing its name to Darkcoin two weeks later before rebranding again to Dash in March 2015 in an effort to positively change its image. Dash is an open-source blockchain and cryptocurrency focused on offering a fast, cheap global payments network that is decentralized in nature. According to the white paper, Dash seeks to improve upon Bitcoin (BTC) by providing stronger privacy and faster transactions. Dash, whose name comes from "digital cash," was launched in January 2014 as a fork of Litecoin (LTC). Since going live, Dash has grown to include features such as a two-tier network with incentivized nodes, including "masternodes," and decentralized project governance; InstantSend, which allows for instantly settled payments; ChainLocks, which makes the Dash blockchain instantly immutable; and PrivateSend, which offers additional optional privacy for transactions.
