Building ZK Registries Onchain with Rarimo

This week, Anna speaks with Lasha Antadze, co-founder of Rarilabs and Rarimo, about the evolution of digital identity systems. Lasha shares his journey from working with government eID systems to building decentralized identity solutions using zero-knowledge proofs. The conversation explores how Rarimo is taking a fundamentally different approach to identity verification by keeping all processing client-side, from passport scanning to biometric verification. This enables new use cases like censorship-resistant voting systems and privacy-preserving account recovery, while avoiding the traditional pitfalls of centralized identity providers. The discussion also covers the challenges of building trust in cryptographic systems, the potential applications of client-side ZK proofs for AI governance, and how Rarimo is working to make identity tools that are both powerful and accessible to everyday users. This episode provides a fascinating look at how zero-knowledge proofs are reshaping our understanding of digital identity and privacy. Further reading:
