Ethereum

is there an onchain protocol that lets you verify ownership of multiple addresses similar to farcaster verifications?

you can do this on icebreaker by linking multiple wallets

I am interested in the answer for this so that icebreaker can honor and promote it for those who want it

We have a way to generate a ZKP of an address that is onchain provable, but don’t actively promote verifications onchain because that is terrible privacy architecture. 

@sin do you know of any?

smart contracts give you strong guarantees of availability, uptime, and are permissionless

feels like this type of primitive should exist onchain somewhere. maybe namechain

I don't know of any beyond icebreaker. I think the witnessed attestation model is probably the best here, then let a user reveal/zk-reveal/publically onchain reveal as they see fit.
