In this episode, Anna Rose and Guillermo Angeris catch up with Muthu Venkitasubramaniam, Professor of Computer Science at Georgetown University and cofounder of Ligero. They discuss how Ligero’s small memory footprint makes it a good choice for client-side proving, as well as the importance of programmable compliance in blockchain. The conversation explores the differences between ‘MPC in the head’ and error-correcting code perspectives, and how well-established primitives influence the design of modern ZK systems. They also debate the challenge of adding ‘ZK’ privacy back into systems without it, why proving EVM traces may be absurd, and what kinds of guarantees might exist around the results of vibe coding.

In this episode, Anna Rose and Nico Mohnblatt speak with Dan and Sinu from TLSNotary to trace the project’s journey from early Bitcoin forum ideas to its current role as a foundational protocol maintained by PSE. Dan recounts the origins of TLSNotary as a tool for cryptographically proving web data, while Sinu explains how the project was revived to provide modern TLS attestation.

The conversation covers the use-cases for verifiable web proofs, the different modes these interactive protocols can take, and the broader impact of this technology on leveraging siloed user data.

In this episode, Anna Rose and Nico Mohnblatt speak with Goblin Oats from Tonk and grjte from Bain Capital Crypto to explore the emerging world of local-first architecture.

Goblin shares the evolution of Tonk from an experimental lab working on blockchain games to a product that enables anyone to build personalised local-first software using natural language. grjte discusses her Groundmist project exploring personal data lakes and the intersection between local-first systems and the AT Protocol. The conversation explores the technical foundations of local-first software, including Conflict-free Replicated Data Types (CRDTs), parallels with blockchain systems, and how ZK proofs show up within cloud-optional architecture.

In this episode, Anna Rose speaks with Florent Tavernier from Self and Marek Olszewski from Self and Celo to explore how Self are bringing identity onchain using ZK, the Sybil protection that offers, and the origins of OpenPassport.

The discussion covers Self's approach to supporting different forms of ID, the challenges of disparate cryptographic standards, and how government signatures can be used to bootstrap onchain identity systems.

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.
