Dash (DASH) is a privacy-centric cryptocurrrency with close to instant transactions. It is based on the open source Bitcoin code, but it has a two tier network that improves upon it. Dash allows you to remain anonymous while you make transactions online, similar to cash offline. Bitcoin transactions are published publicly on the blockchain and it’s possible to find the identity of the recipient or sender. With Dash the anonymization technology makes it impossible to trace the user.
The Dash project clearly outlines the importance of a anonymous blockchain transactions. It achieves this through a mixing protocol utilizing an innovative decentralized network of servers called Masternodes, avoiding the need for a trusted third party that could compromise the integrity of the system.
