I'm curious from the technological/economical standpoint about other truly decentralized projects (i.e. no premine, etc.). I'm not interested in bitcoin forks. It's been over a decade since we've had bitcoin and surely there have been attempts to create a better version of it.

Recently, I've heard about KASPA which aims to be what silver is to gold. Although the project's Github doesn't seem very active lately.

Do you know any other decentralized projects with a theoretical potential (not to overcome bitcoin, obviously, but to have a valid use case, at least)?
