The argument I hear is it’s adjacent to the lightning network and not on top. I would argue that you can’t have a mint without running a lightning node. Curious to see what others think
I tend to call Cashu a “permissioned L3” since you still need permission from the custodian to send ecash
Right. If you can't have a mint without Lightning, it's an application protocol built on Lightning. It's built on top of Lightning. It's a layer on top of an existing second layer. It's layer 3, IMO. But yes, ask calle that invented it 🥹 He knows best.
