Is Farcaster an app or a protocol? Is this app using it?

Here for the vibes.

Farcaster = the protocol
Warpcaster = the app

Gotcha.  Yeah, @dwr.eth has been teasing quite a bit of info on protocol since they moved to OP mainnet.  Not sure I understand most of it.

But I’m here for it 🫡

Thanks - what I didn’t get was when @dwr.eth says “I have invites for Farcaster”, what does he mean? Perhaps setting up the “protocol” account?
