Pivx was originally cloned from the Dash code base and called darknet. It carries most of the features created by Dash groups v10 release like instant send pivx calls swiftx, and the incentivized masternodes cleary first created by Dash and copied by many, as well as the governance system. At least they took a few features from some other coins too so its not a complete dash copy and paste. Zcoin tech and pos was used as the main differentiators in pivx.
