Dash (DASH) uses a new chained hashing algorithm approach, with many new scientific hashing algorithms for the proof-of-work. DASH aims to be the first privacy-centric cryptographic currency with fully encrypted transactions and anonymous block transactions, this feature is called PrivateSend and can be found on the official Dashcore wallet.
PrivateSend mixes your DASH coins with other users who are also using this feature at the time, making your transactions untraceable.
Users can also earn Dash rewards by hosting a master node to help maintain the Blockchain. One must have a balance of at least 1000 DASH in order to host a Dash master node, this collateral is required to avoid 51% attacks on the network.
