Are there any coins that do proof-of-useful-work? Like solving scientific problems with the compute cycles?
The thought of all this pointless computation is painful.

- YossarianFrPrez 3y agoIn some sense, the introductions of scientific papers are supposed to be / are the original 'verification blockchain' albeit one done with human minds and messy research projects.

- bawolff 3y agoBasically none that actually work. The computations done in bitcoin aren't just to waste energy, they are meant to prove you have the ability to waste energy. That means you need a problem where: there are infinite instances, the hardness of an individual instance can be dynamically tuned, there is no central authority needed to give out problem instances, there are no shortcuts or ways to collude to make solving a specific instance easier. Nobody has come up with a useful problem that meets this criteria. It seems hard to imagine anyone will. If you want crypto enviro friendly, proof of stake (like eth) seems like a much more viable path forward. Even better would be to stop using fake money altogether.
- whimsicalism 3y agoAll money is fake. I am not at all a crypto evangelist, but it has its uses - especially outside of the West and in remittances.
- bawolff 3y agoIf you prefer, you can read that sentence as stop using cryptocurrency based money and use USD, gold, or whatever instead. Or if you really want electric money, use Chaum style digicash instead. It long predates bitcoin, but basically has all the benefits except technically having a central authority except you dont even have to trust the central authority.
