This coins is not dead, don't worry!
As some of you might know, Citizencoin code is based on Badgercoin and that's why there are problems with staking. I tried changing code base to Libertycoin, it works little bit better, but I'm still not satisfied, I wan't flawlessly working coin.
Can you suggest working X11-POS coin, that I could use as base?
MastiffCoin had a perfect PoS transition, go check their code out.
