That's my biggest problem with bitcoin. If someone figures out how to reverse sha256 they could just mine blocks here and there without attracting too much attention, but in reality the whole thing would be on shaky ground and truly worthless.

You should try to reverse sha256. If you can do it ill give you $100.

I am trying. There has probably never been a prize this large for solving any math or programming problem.
