Dash (Ticker symbol: DASH) is a digital currency based on the Bitcoin software. Created by software developer and financial advisor Evan Duffield, Dash's primary objective is to offer its users a secure, privacy-centric alternative to Bitcoin. Dash is the leading anonymous digital currency; it improves upon the well-established Bitcoin source code and features a custom, decentralized implementation of the CoinJoin transaction protocol that removes the need for Dash users to entrust their privacy to a third party.
Every Bitcoin account and associated transaction is stored on a ledger, or "blockchain". This information is publicly available, and is retained in perpetuity. In contrast, Dash's underlying technology masks the link between the sender and receiver on the blockchain, affording its users a high degree of privacy
