Who is the dev?
My opinion is that the problem starts when there's PoR and scrypt PoW running in the same time. I think that a better idea would be to have pure PoR or PoS/PoR, because it's safer. Maybe instead of repairing blockchain every day (or twice a day), it would be better to finish PoW and switch to pure PoR (or rather PoR/PoS) now? And I wonder if the PoR block minting is a good idea (let's compare it to curecoin, where the research makes no blocks but a normal trasfer hashed by asics, here it should be hashed by PoS). By this ocasion the reward algorithm could be improved: no halvings, but more proportional amount of coins to the amount of points in long term.
