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

Opacity

Not trying to argue with Dan, just offering my perspective.

The thesis of Opacity fundamentally is based on how what can be put on-chain is limited by cooperation (signing data) and verifiability.

Most of what there is onchain is financial abstractions. 

Happy to proven wrong ofc. Writing this because i’ve thought very deeply about this particular area. 

I really don’t care about anyone else’s opinion, prove me wrong.

I swear i’m not beefing just pointing out that this pokes into my area of expertise.

Clientside proving of wallet ownership is slow as fuck. Someone should use this idea to speed it up: https://ethresear.ch/t/lookup-singularity-via-mmr/18704

I honestly don’t think ZK proving wallet state has that many interesting use cases.
