random sunday thought: since a message on the farcaster protocol doesn’t validate the fid of the data, could you theoretically build a public but encrypted messaging app on top of the protocol with derived private keys from the user, for p2p or group communication? it wouldn’t pollute your profile because it wouldn’t be tied to your fid or private key but it would take advantage of the network and have everyone onboarded without further setup. I’m sure there are multiple reasons not to do it but would it be possible?
