The former Darkcoin

Dash is yet another fork of Bitcoin core, but designed with faster and more private transactions. Dash stands for “Digital Cash” and is available over Mainnet and Testnet networks.

Addresses Bitcoin’s weaknesses

Dashcoin “fixes” Bitcoin’s issue with the 10 min block confirmation time which makes it more efficient than Bitcoin as confirmations occur in seconds. Dash also incorporates a feature called “InstantSend” which locks the transactions and avoids the Double Spending issue some blockchains have.
