It is a fork of Dynamic(DYN) which is a fork of Dash 12.2, but the difference being Dash is doomed to fail due to Masternodes not yeilding a return on investment over a long period and depreciating incentive.

Credits(CRDS) fixes that with increasing rewards for Masternodes over time and depreciated PoW rewards, this enforces ROI for Masternode operators and increases scarcity and demand of CRDS.

The mining algorithm is also NOT X11. It is Argon2d, far superior and much harder an algo, adding to the intrinsic worth and scarcity of CRDS.
