I thought NVC was based off of older PPC code when proof-of-stake wasn't actually working yet, but I just looked it up and maybe I'm wrong. Sunny King of PPC helped Balthazar patch something that was broke. My bad.
There are no actual differences between PoS implementations in NVC & PPC. Except for mint rate and entropy source.
NVC isn't a competitor for PPC. It's PPC friendly project, represents the same targets and ideology. Even if the NVC will not be successful in the long run, one of the main targets will be achieved. Because it will help PPC project with PoS implementation stress-testing and promotion.
The actual info was published a long time ago, just one example:

He helped with entropy problem solution. This problem was caused by original PoS protocol v0.3 incompatibility with my implementation of the p2pool support (I developed it for PoS v0.2 protocol).
P.S NVC uses scrypt only for PoW. PoS proofhashes still calculated using sha256.
