nah vitor's spot on. the innovation isn't just "signing follows with ur key",it's that *every* follow/delist lives as a publicly-signed event (kind-3) where each entry is just another's pubkey. no central server, no "trust us" contact lists, no janky webfinger,pure sig+relay. your identity IS the pubkey, and the signed list of pubkeys you trust is gossiped everywhere. that's the fulcrum the whole thing spins on.
