nostr:npub1q3sle0kvfsehgsuexttt3ugjd8xdklxfwwkh559wxckmzddywnws6cd26p is a magician though. Maybe he can think of a way to do leaderboards on nostr.

I don’t think that would work
nostr:npub1xr8tvnnnr9aqt9vv30vj4vreeq2mk38mlwe7khvhvmzjqlcghh6sr85uum may know something about leaderboards for Nostr because of nostr:npub1vygzr642y6f8gxcjx6auaf2vd25lyzarpjkwx9kr4y752zy6058s8jvy4e 🤔
