Zero Knowledge

• Year in Review: ZK Podcast in 2025 & Beyond

  In this end-of-year episode, Anna recaps the major ZK themes of 2025 and gives a preview of what’s coming in 2026 — new episodes, a mini-series, zkSummit14, and the rollout of ZK Mesh Plus, a unified space for newsletters, educational content, and events. She highlights this year’s core research threads, from lattices and Ligero to quantum security, ZK-ID systems, emerging applications, and the ongoing push toward better proving benchmarks. Anna wraps with reflections on why privacy tech is becoming more urgent in the age of AI and what the community will be exploring next year.

• Pratyush Mishra on Tiny Proofs, Folding, Low-Memory SNARKs and More

  In this episode, Anna Rose and Nico Mohnblatt catch up with Pratyush Mishra, Assistant Professor of Computer and Information Science at the University of Pennsylvania. They discuss the various themes in his ZK research and some of the works he has been a part of in the last few years. They explore how Garuda and Pari achieve extremely small SNARK proofs, how Arc facilitates hash-based folding, proximity proofs with FICS and FACS, his work on low-memory SNARKs, and ZK applications outside the blockchain space. Pratyush shares how these ideas intersect with one another, from faster proving to smallest proof sizes to real-world uses. He also touches on his collaborations with other leading cryptographers like Benedikt Bünz and Alessandro Chiesa, and how ZK is finding its place in broader computer science.

• Lattices, Folding, & Symphony with Binyi Chen

  In this episode Anna Rose and Nico Mohnblatt chat with Binyi Chen, researcher at Stanford University. They discuss his work on lattice-based folding schemes, revisit LatticeFold and LatticeFold+, and cover how lattices enable low-cost, post-quantum-secure folding by replacing Pedersen hashes with Ajtai commitments. They discuss the early folding work from 2023 and how it has evolved and explore the advantages of lattices over other approaches in the folding context while also highlighting their tradeoffs. Binyi goes on to introduce Symphony, his new work that eliminates the need to implement Fiat-Shamir in the recursive verification circuit, and describes how that improves efficiency and removes the chances for a KRS-style attack.

• The Quest for Practical iO with Machina iO

  In this episode, Anna Rose and Tarun Chitra chat with Sora Suegami and Enrico Bottazzi from Machina iO. They explain indistinguishability obfuscation (iO) technology and how they are working to bring this powerful cryptographic primitive from theoretical territory into the practical world. They discuss how the pair got into iO and how new assumptions like all-product LWE and evasive LWE will help bridge theory to practice. They explore the benchmarks, the challenges and opportunities of this cutting-edge privacy cryptography and cover potential optimizations and real-world uses. While iO is still far from being truly practical, their work shows tangible steps ahead and offers interesting insights into how this could actually work.

• Countdown to Q-Day with Project 11

  In this episode, Anna Rose chats with Alex Pruden and Conor Deegan from Project 11. They revisit the topic of quantum computing and explore the threat it poses to cryptographic systems like blockchains. As blockchain technology becomes increasingly integrated into global financial infrastructure — especially through stablecoins and banking rails — the stakes for quantum security continue to rise. Alex and Conor break down which algorithms are most at risk, why simple network upgrades won’t be enough, and what users will need to do to protect their own funds. They also outline potential mitigation strategies, including how Project 11 is approaching the challenge with post-quantum signature schemes, secure vaults, and a global namespace to coordinate user migrations ahead of “Q-Day.” The conversation also touched on how post-quantum thinking overlaps with zero-knowledge research, as hash- and lattice-based SNARKs offer resilience against future quantum attacks.
