In this episode, Anna Rose chats with David Z and Oleksandr (Sasha) from Privado ID and Billions Network about the evolution of ZK-based identity systems, tracing their roots back to iden3 in 2018, one of the earliest projects to pioneer ZK for on-chain identity.
They discuss their origin as the iden3, their creation of the influential Circom DSL, the move into Polygon ID, the spin-out as Privado ID with a focus on B2B privacy tools and verifiable credentials, and the recent launch of Billions Network, which aims to build a scalable network of humans and AI agents with mobile-first verification and progressive proofs.
They compare their broad, composable approach to projects like Self, Rarimo, and ZK Email, while highlighting future plans for reputation layers, on-chain economies, and AI agent identities to enable accountable interactions in a decentralised world.
