Hi @Nesopie n

Can you provide a sequence diagram?, It will help to explain your idea and make the protocol more understandable.

Hi @chiro-hiro !
We've added some more diagrams

@Nesopie Thankyou for adding it, Let me ask the team to have a view

Thanks for the update @Nesopie, everything looks better now.

1/ In your sequence diagram, I think you need to clarify that only user is able to obtain vanity address otherwise it will raise the concern of privacy.
2/ Homomorphic addition wasn't clarified, i think it is also play an crucial role in your protocol.
3/ Adding security consideration section would help to clarify the status of the project, as you known all protocol need to be audited.
4/ There are some contents were derived from https://cryptobook.nakov.com/asymmetric-key-ciphers/ecies-public-key-encryption. Your should add references section.

1. Provided miner is relatively random and is not spiteful the vanity public key will never be acquired by anyone else. We are also planning to implement FHE based solutions which will resolve this problem as well but the idea here is that no one expect the user will be able to calculate the private key. Zanity is a demonstration of what ECIES can be used for can be used and how it can reduce trust-less interactions between a person with computational needs and a resourceful person ,without a layer of escrow.
2. Homomorphic Addition here meant point addition of public keys in the context of Private keys.
   3,4. Yep we will be definitely adding security considerations and references section.

(1) is strong, would love to see it in your proposal. Thanks and have a nice weekend 😁

• We explored implementations of FHE and found a real absence of any performant solutions and are motivated to do it ourselves also as an other grant proposal fr!.
  • Sha256 with FHE
  • Point addition with FHE.
• We also secured confidence in implementing this in RISC0 counterparts like SP1 for better understanding cause the miner ,a resourceful guy, is taking the computational effort.
• We also believe people don't want their vanity address to be obscured after paying a hefty miner's fee for it .
• Existence of such an implementation will crack open astronomical possibilities for privacy enabled bridging solutions.
• ECIES with all the extended cryptographic library stack will be the main focus for this proposal 😇.

@chiro-hiro any update on the evaluation of this proposal?
