Chainmail: ZKP Email Marketplace 📧🛡️

Chainmail is a marketplace for emails verified using Zero-Knowledge Proofs (ZKPs) to prove the authenticity of the sender whilst preserving the anonymity of the recipient.

🗺️ Project Overview

The project leverages ZK Email to generate ZKPs of emails via their DKIM signatures.

By analysing the DKIM signature in the header of an email, we can verify the public key of the sender's domain. Find more details on DKIM here.

After verification, a ZKP of the email is generated via a circom circuit to verify the DKIM signature, provide public signals for details such as the sender, subject, body hash & ETH address of the owner.

Chainmail then provides a smart-contract backed marketplace to facilite the sale and transmission of these emails between buyers & sellers.

Transaction disputes are mediated via a Chainmail Voting Token.

🎯 Project Goals

Empower information distribution: Provide a platform and mechanisms for encrypted transmission of email data.
Verify authenticity: Ensure that information transferred between parties is authentic.
Protect privacy: Redact the identity of an email recipient
