Have anybody received anything for Proof-of-stake mining?
Yep. For PoS success you should have matured non-coinbase coins (i.e. coins that you can spend) and these coins should be kept in your wallet more than 150 blocks.
p.s. Also important to start komodod with
-gen -genproclimit=0
for staking only and
-gen -genproclimit=x
, where x is number of your cores for
mining + staking. Remember, if generate is false - you can't stake.
