In this episode, Anna Rose chats with Théo Madzou and Michael Elliot from ZKPassport and Obsidion about their ZK-based identity solution. Théo shares his start in ZK through ZK Hack hackathons using Noir, while Mike shares his path from Bitcoin and MakerDAO to working on zkID systems. They explain how they teamed up to build ZKPassport, a non-profit public-good ZK identity solution project,and how they plan to bring it into Obsidion, a for-profit, privacy-focused fintech-style application that they’re working on. They discuss Noir's evolution and their contribution to this accending zkDSL, how subcircuits and subproofs enable mobile proving, how ZKPassport differs from projects like Self and Rarimo, how they integrated ZKPassport in the wild with DevCon and Aztec, and their plans for better UX and user-friendly apps.   Related Links ZKPassportObsidionZKPassport: Where are we now?ZK HACKNoirAztec   Related Episodes Episode 358: Building ZK Registries Onchain with RarimoEpisode 377:Evolving ZK Identity from Iden3 to Privado & BillionsEpisode 366: Bringing ID Onchain with Self     ZK Whiteboard Sessions is an educational video series produced by ZK Hack.
