As of version 188.8.131.52 PoW mining will begin to be phased out.
Starting at block 5,600,000 a Proof of Work block will only be accepted if it comes after a PoS. So no more flash mining! Then at block six million, PoW will only be allowed if the PoS block chain stalls and there are no blocks within 10 minutes. Basically I left as a just in case.
