In this episode, Anna Rose and Tarun Chitra catch up with Kostas Kryptos from Mysten Labs to explore the latest ZK innovations being built on Sui. Kostas shares updates on zkLogin and introduces zkAt (ZK Authenticator), a new research project enabling programmable and updatable access control for accounts where Groth16's trusted setup and the generated toxic waste is used in a very novel way. 

This discussion also covers Sui's ambitious plans to become quantum-ready, including their innovative approach to transitioning existing EdDSA accounts to post-quantum security using STARKs without requiring users to change their addresses. They touch on ZK Tunnels, working with the Greek stock market, and how ZK is breaking out of the  web2/web3 paradigm.

In this episode, Anna sits down with David Wong from zkSecurity to discuss the impact of AI on the field of zero-knowledge auditing. David shares how his team is integrating AI agents into their workflow, the opportunities and challenges this brings, and how the role of the human auditor is evolving as AI becomes more capable.

They also cover the unique aspects of auditing ZK-based systems, how this is different from smart contract auditing, and the broader implications of AI for security in cryptography and blockchain. The conversation touches on the ethical considerations of AI in security, the future of the auditing profession, and the ways ZK and AI are increasingly intersecting.

In this episode, Anna and Nico speak with Abhi Shelat and Matteo Frigo from Google about their work integrating zero-knowledge proofs into the Google Wallet. They discuss the technical decisions behind the Anonymous Credentials for ECDSA system, including the challenge of designing a proof system where proving must be efficient enough to run on the client device in a large-scale consumer application, and how they design a system using sumcheck and Ligero to overcome NTT issues.

The conversation also touches on the process of standardization, the return of ZK to its privacy roots, and the broader significance of seeing advanced cryptography adopted by a major tech company outside the blockchain space.

In this episode, Anna speaks with Madhavan (Maddy) Malolan from Reclaim Protocol about his work on zkTLS and its applications in web data verification. Maddy shares the journey of building Reclaim, from initial attempts at implementing DECO to developing their current proxy-based solution.

The conversation explores the technical challenges of implementing zero-knowledge proofs for HTTPS connections, comparing proxy and MPC approaches, and discussing security considerations. Maddy explains how Reclaim is bringing ZK technology to mainstream applications, focusing on three key verticals: education verification, employment history, and financial background checks.

In this episode, Anna and Nico speak with Matthew Klein and Albert Garreta from Nethermind about their work implementing and advancing lattice-based cryptography systems, particularly focusing on folding schemes and their applications in zero-knowledge proofs.

Matthew and Albert share insights from their implementation of LatticeFold and discuss the evolution of lattice-based systems, including newer developments like LatticeFold+ and Neo. The conversation explores the unique challenges and opportunities of working with lattice-based constructions, from performance optimizations to post-quantum security considerations. They also dive into their work on post-quantum signatures for Ethereum, light zkML solutions, and the Zinc project, which offers a novel approach to handling integer-based constraints in zero-knowledge proofs.

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.
