To put it in a nutshell, Dash is an open-source project that aims to create a user-friendly, scalable, and straightforward solution for the payment industry. Since its launch in 2014 from a hard fork of the Bitcoin protocol, the project went through several evolutions and rebranding processes, going from “Xcoin,” to “Darkcoin” before being rebranding to “Dash” in reference to “Digital Cash.”
