Sean Bowe on Tachyon and the Evolution of Zcash Jan 21, 2026

Show notes

In this episode, Anna Rose catches up with Sean Bowe, a Zcash core developer now leading work on Tachyon, the upcoming Zcash shielded pool upgrade. They discuss the evolution of Zcash’s technical roadmap over the past five years and how it has influenced the design of Tachyon. Sean then walks through the cryptographic ideas behind Tachyon, including its proving systems, new techniques for pruning nullifiers without disrupting other parts of the protocol, and how the upgrade aims to address Zcash’s remaining scalability bottlenecks. They also explore plans for Zcash governance, wallet UX, and the long-term outlook for privacy-focused zero-knowledge systems.

Pratyush Mishra on Tiny Proofs, Folding, Low-Memory SNARKs and More Nov 26, 2025

Show notes

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. Related Links

Lattices, Folding, & Symphony with Binyi Chen Nov 19, 2025

Show notes

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 Nov 12, 2025

Show notes

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. Related Links

Countdown to Q-Day with Project 11 Nov 05, 2025

Show notes

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.

Kevin Lacker on AI-Assisted Theorem Proving and Acorn Oct 22, 2025

Show notes

In this episode, Anna Rose and Guillermo Angeris talk with Kevin Lacker, creator of Acorn, a theorem prover utilising AI. They explore what theorem provers are, their history, and how they're used today. Kevin shares how Acorn brings in AI to simplify the proving process, letting users naturally write mathematical statements while the system checks the correctness of those statements. It's built to feel more like natural math, unlike tools like Lean that demand every step. They also explore the benefits of including AI in math, and also the challenges that come with it such as hallucinations, and how Acorn could speed up research in areas like zero-knowledge proofs. The dicussion also covers the history of mathematics, community building around Acorn and its open math library, acornlib. Related Links

Payy and Payy Card, the Undoxable Credit Card Oct 15, 2025

Show notes

In this episode, Anna Rose and Tarun Chitra catch up with Sid Gandhi and Calum Moore from Payy to discuss the Payy private payment system and the newly released Payy credit card. They explore their focus on building a user-friendly privacy focused product, how ZK tooling advancement makes this possible, and a walkthrough into how it works with the Visa remittance system. Sid and Cal explain Payy's design as a ZK Validium rollup on Polygon, using client-side proofs and a Merkle tree to ensure privacy and compliance. The discussion also delves into the history and past challenges of self-sovereign payments; how self-sovereign money goals were overshadowed by speculation, why many new stablecoin projects feel like a step back to traditional finance, and how privacy-focused payments are making a comeback in 2025.
