  • Building ZK Registries Onchain with Rarimo

    Building ZK Registries Onchain with Rarimo
    Apr 23 2025
    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:

  • ZK Benchmarks with Conner Swann

    ZK Benchmarks with Conner Swann
    Apr 9 2025
    In this episode Anna explores the contentious topic of ZK benchmarking with Conner Swann, founder of ProofLab. Drawing parallels with AI's development, they explore how tools like ProofLab could help standardize benchmarking across dimensions like speed, cost, and security. The conversation touches on the importance of formal verification and real-world workload testing, while considering how better benchmarking could accelerate ZK adoption and potentially lead to ZK's own 'ChatGPT moment' Related links:

  • The Founding of Zero Knowledge Systems with Austin Hill

    The Founding of Zero Knowledge Systems with Austin Hill
    Mar 25 2025
    This week, we present the third installment in the Zero Knowledge Systems story. In this episode, Anna chats with Austin Hill, one of the original founders of Zero Knowledge Systems. They explore the company’s early days, Austin’s background in tech, and what this scene in Montreal was like in the late ’90s. The conversation covers fundraising during the dot-com boom, Zero Knowledge Systems’s ambitious vision for internet privacy, its flagship product Freedom, and how the company pivoted from a broad individual privacy mission to a more focused B2B approach. They cover Austin’s journey after ZKS—including how he discovered Bitcoin, co-founded Blockstream, and navigated the challenges of building a business around open-source infrastructure. He also discusses a new project he's involved in, which ventures into a completely different field—material nanotechnology. We encourage you to check out the first two episodes of the series here and here before diving into this one. Related links:
