ZCash, one of the anonymous currency troikas, has been controversial in its approach to financing, and in order to keep the project running, the ZCash team has ordered that 20 percent of the first four years of mining be owned by the team, which is unfair to the diggers, so the miners have split a ZClassic from ZCash. ZClassic gives all the proceeds from the mine to the miners, but this raises the question of how much money is needed for the development of the project, which depends only on the contribution of the community. So the development progress is not satisfactory. Finally, three former U.S. government military personnel split a more perfect version of ZClassic: ZenCash. ZenCash is the world's first private, distributed, reliable anonymous currency, ZenCash provides private communications, anonymous distribution of content and other functions. ZenCash was split by ZClassic on May 30, 2017. ZenCash was created by ZClassic. Some of these ZClassic developers believe that in addition to removing ZCash's controversial two points (20% reward and slow start), they can actually add some other currency features to Zclassic's: such as Dash's de-centric anonymous management organization DAO, Decred's consensus mechanism for self-voting, and so on.

Zclassic was split from zero-currency Zcash, eliminating previous rewards for founders.

ZClassic (ZCL) Menetnet will be officially released on September 6 and the test network will end at the end of August.
