I think there’s probably a program you could write that finds low values of SHA256(SHA256(x)) really fast. I mean, a program you could write if you knew it, I don’t think anybody can think of such a program. But since it’s possible, and solves proof of work for adding bit coin blocks, it’s like a real life cheat code. You enter the code into your computer and then you have a lot of money.
