Simple: it’s game-theory. It’s not even possible to built something like $UP on eg. Eth because you run into gas fee issues. Right now it’s only possible on a L1 like Tezos. What makes it special? It’s the first project that I know tries „simulate“ the game-theory of BTC, improves it, and applies it to a eco-friendly L1 (Tezos). As soon as our new whitepaper is available you can have a deeper look into the math of $UP. Happy to answer any questions though.
