Private addresses connected to Farcaster protocol

1. Web app with open source repo so you can run locally if you want

2. Ability to sign from two addresses: a) your Farcaster custody address b) an arbitrary ETH or SOL address

3. Publish the ZK proof to blockchain / website / API to start; if started to get adoption, could figure out best way to add to protocol

a. Address X (publicly revealed) is connected to a unique FID Y (private); address X cannot be reused in the proof system for another FID.

b. Bonus points if you could include some generalized information about the FID (<# fid, # followers as of proof date).

You could imagine token pages showing way more Farcaster ownership by done anonymously but provable thanks to ZK
