Is there something unique or special about the private keys that are guessed? This seems like an incredibly wasteful allocation of compute (which wouldn’t be surprising given that it’s bitcoin but still)

I had the same reaction. Isn't Bitcoin wasting enough energy as it is?

What if it’s 100% green energy? Is it a waste?

Given that green energy is currently finite, and shortfalls are (generally) made up for by non-green energy, yes.

I think the puzzle idea is that, if you could figure out a weakness in the hash, you could claim it faster than the brute force approach. So each prize that's claimed "on schedule" supports the idea that there aren't any widely known shortcuts. Obviously if you found a shortcut in the hash you might do other things first, but I think that's the idea.

Hmm yeah if I cracked Bitcoin then last thing I'd do is claim a prize that gave away the fact that I'd cracked Bitcoin.

There is a difference between a weakness and complete breakage. You might have a small edge over brute force, but not enough to reverse any public key. This acts like a canary for weaknesses.

some people just want the cred though. their name will be immortal and live through history as being something, or some such nonsense that feeds an ego.

also, if you were the type that thinks bitcoin is lame, this could be a way of undermining the concept to the point that people no longer use it because it's not secure as it was touted

Of course. It's still energy produced which could be used for something that is not a scam; that is not just funding North Korea with extra steps.

Why?

Can't we come up with puzzles where at least something of value is created when the puzzle is solved (and a tremendous amount of resources is not wasted)?

> puzzles where at least something of value is created when the puzzle is solved

What puzzles create something of value when they're solved today? A puzzle is typically a thing you do for fun and entertainment, not something you try to solve for the purpose of creating value.

I guess you're thinking more about logic/mathematical puzzles and alike? Would make sense in that case, but that's not the only type of puzzle.

I would argue that it's still a waste, because that energy could be put to an otherwise better use. Now that energy has to be replaced by a non-green counterpart since it's been spent.

It's all one energy market however. It's a bit a of rough approximation, but green energy wasted on unnecessary purposes is green energy not used for necessary things.
