Dash is a cryptocurrency that emphasizes transaction speed. Dash maintains a two-tier architecture with miners and “masternodes” that allow the Dash network to perform near-instant transactions (known as InstantSend). Dash network functions are handled in two different ways. Creating new blocks is handled by Dash miners in a manner that is similar to other altcoins. The second tier of the Dash network is a set of “masternodes” which perform PrivateSend, InstantSend, as well as some governance functions.
