The Quantum Question Panel – Live from zkSummit14
3w ago00:58:55Tap to summarizeThis episode was recorded live at zkSummit14 in Rome. In it, Anna and Nico Mohnblatt hosted the live ‘Quantum Question’ panel which began as an interview, but became something harder to categorize: part seminar, part group therapy, part improv theater, and — depending on the timeline you expect for viable quantum computers — part emergency briefing. The logistics of the panel were really unusual. The guests were meant to be Justin Drake and Dan Boneh, but Dan’s flight was delayed. And so the panel began with just Justin Drake and the hosts — what someone in the room jokingly described as the highest moderator-to-panelist ratio in zkSummit history. To compensate, the format broke open: researchers from the audience, including Daira-Emma Hopwood from the Zcash team and Jens Groth (author of Groth16), joined the conversation. A park bench materialized in real time. The conversation veered into the history of quantum computing research, why Shor’s algorithm threatens today’s public-key cryptography and pairing-based SNARKs, fault-tolerant ‘logical qubits’, physical qubit fidelities, and why neutral-atom machines—despite slower cycle times—may be the most practical path to ‘Q-Day.’ The group also debates the rush-to-post-quantum pitfalls, the benefits of lattice-based post-quantum schemes versus hash-based ones, and how hybrid transitions are unfolding in practice. This was a truly chaotic, spontaneous, informative and fun session at zk14 with some great contributors from attendees and community members, we hope you enjoy it!

Transcribe →From Access Control to Encrypted Execution with Auryn Macmillan
4w ago00:53:23Tap to summarizeIn this episode, Anna chats with Auryn Macmillan, founder of Gnosis Guild. They check in on Zodiac, which started as a DAO toolset and has evolved into a modular access control suite for on-chain entities. They discuss the state of DAOs today—what's worked, what hasn't, and how tools like Zodiac might have mitigated large-scale multisig hacks like the recent Bybit exploit. The conversation then shifts to The Interfold (formerly Enclave), Gnosis Guild's new project combining FHE, ZK, and MPC to create encrypted execution environments. These enable multiple parties to collectively compute over private data and produce a verifiable output without any single trusted coordinator. They explore use cases like secret ballot voting and sealed bid auctions, the broader potential for collaborative analytics and private AI training, and how this fits into the larger privacy ecosystem.

Transcribe →Quantum Advances, Hybrid Signatures and SNARKs to the Rescue with Dan Boneh
May 601:24:35Tap to summarizeIn this 400th episode, Anna Rose welcomes back Dan Boneh, professor of computer science and electrical engineering at Stanford University, for a wide-ranging conversation on quantum computing, post-quantum cryptography, and the evolving role of ZK. They discuss Google's recent quantum algorithm announcement—what the paper actually showed, why it was proven in zero knowledge, and the cryptographic ideas embedded in the work. Dan shares his perspective on quantum timelines, the risks of rushing the post-quantum transition, and why algebraic signatures deserve more attention than hash-based ones in the blockchain world. The conversation covers hybrid signature schemes, the web's quiet transition to post-quantum cryptography, and the intersection of AI and ZK. Dan also highlights witness encryption, explains why encrypted mempools are generating new research questions, and closes with an update on the Ethereum Foundation's Proximity Prize.

Transcribe →Is ZK dead? Or has it just begun? with the ZK Pod co-hosts
Apr 2201:02:44Tap to summarizeIn this episode, Anna is joined by co-hosts Guillermo Angeris, Nico Mohnblatt, and Tarun Chitra for a reunion on this 399th episode. They reflect on how they each joined the show and how both the podcast and the ZK space have evolved over time, before diving into discussion on whether ZK is ‘dead’ or simply maturing. They explore its shift from niche research to hype-driven narrative to becoming a widely used but increasingly invisible piece of infrastructure. They go on to discuss the changing landscape of ZK companies, the explosion of new applications, and the trend of teams using ZK as an implicit primitive rather than a headline feature. The episode closes with a broader reflection on decentralisation, usability, and what the next phase of ZK adoption might look like.

Transcribe →Verifiable Databases with Shyam & Emanuele from Provably
Apr 800:56:15Tap to summarizeIn this episode, Anna Rose and Nico Mohnblatt speak with Shyam Duraishwami and Emanuele Ragnoli, co-founders of Provably. They trace the origins of Provably, from early work on data ecosystems and blockchain infrastructure to the launch of their verifiable database approach, exploring how advances in cryptography and database theory enabled this shift. The conversation dives into what a verifiable database actually is and how this contrasts with Merkle-based systems and zkVMs, explaining how Provably’s use of polynomial and vector commitments enables performance that scales with query complexity rather than dataset size, opening the door to large-scale, real-world applications. They close with a discussion on emerging applications from proving insights over private blockchain data to enabling verifiable analytics in Web2 and multi-agent systems—and the broader implications for data integrity in an increasingly data-rich world.

Transcribe →lean Ethereum Part 5: Devnets & Upgrade Coordination with Will and Raúl
Mar 1800:39:06Tap to summarizehttps://youtu.be/Ul2bs8INF0k In this episode Nico Mohnblatt chats with Will Corcoran and Raúl Kripalani from the Ethereum Foundation. This is part 5 in the 6-part leanEthereum miniseries, shifting focus from the cryptographic primitives and LeanVM stack to the real-world integration happening through devnets, specs, and cross-team coordination. They dive into the human coordination layer, how independent teams align on post-quantum signatures, SNARK aggregation, and protocol changes, plus the networking upgrades needed for larger payloads. Raúl explains the shift from today's libp2p stack to a purpose-built Eth P2P next-gen version optimised for Ethereum's workloads, including better broadcast layers, erasure coding, and control planes to handle bandwidth competition between execution and consensus layers.

Transcribe →lean Ethereum Part 4: leanVM, a Custom VM for Signature Aggregation
Mar 1100:32:55Tap to summarizehttps://youtu.be/YWkyvTrwtQU In this episode of the lean Ethereum miniseries, Nico Mohnblatt speaks with Thomas Coratger and Emile from the Ethereum Foundation about the design and implementation of LeanVM, a minimal zkVM created to support post-quantum signature aggregation on Ethereum’s consensus layer. They explain why the team chose a VM architecture over fixed circuits and how LeanVM takes inspiration from Cairo with just 4 opcodes and 2 precompiles to keep the instruction set extremely small and make formal verification easier. The conversation also covers LeanVM implementation choices like using Plonky3 and WHIR for efficient proving on CPUs, benchmarks for aggregation speed, and the role of Python specs in testing client interop. They share ongoing efforts to optimize low-level primitives and invite community input on the project.

Transcribe →lean Ethereum Part 3: Security of PQ SNARKs and an update about the Proximity Prize
Mar 400:36:43Tap to summarizehttps://youtu.be/v8SGKS3T-3A In this episode, Nico Mohnblatt speaks with Giacomo Fenzi from EPFL and Antonio Sanso from the Ethereum Foundation. For this 3rd instalment of the lean Ethereum miniseries, they talk about the theory and security behind post-quantum SNARKs. They dive into the hash-based proof systems underpinning LeanVM, multilinear approaches like sumcheck, and how these fit into Ethereum's post-quantum upgrades. They cover the $1M Proximity Prize and the recent wave of papers on proximity gaps, correlated agreement, and list decoding. From negative results near the Elias bound to breakthroughs beyond the Johnson bound for certain codes, the discussion explores how new results slightly degrade conjectural security, why the 128-bit threshold still matters, and what it means to move from conjectural to provable security in large-scale systems like Ethereum.
