Is this PoS only? In this case, maybe parameters are bad. I have got coins in wallet and i could go staking but first, my blocks need to mature. So i have to wait till someone else does the staking. Is anyone able to bail us out of the near-deadlock ?

Such things never happen to oldschool PoS coins such as PPC, NVC, DMD, CLAM, etc. Perhaps their choice of PoS parameters was better?

EDIT: Someone said there is no wallet. I got my wallet via
