Episode 188: Analyzing Osmosis & Preventing MEV with Sunny and Dev

This week, Anna and Tarun chat with Sunny Aggarwal and Dev Ojha about their new project Osmosis, an AMM built into the Cosmos ecosystem using the IBC interoperability protocol.

Osmosis brings some interesting innovations to the AMM table, starting from the seamless IBC integration to customizable bonding curves and per-pool governance to promote experimentation. Sunny and Dev are also very passionate about the topic of MEV, diving into the various types of value extraction, how MEV is mitigated on other networks and how it could be largely eliminated on Osmosis through threshold cryptography.

Thanks to this week’s sponsor, Least Authority!

Least Authority will soon be releasing a whitepaper on ZKAPs – Zero-Knowledge Access Passes. ZKAPs is an anonymous, token-based authorization protocol that facilitates an online exchange of value while disconnecting the necessary payment data from the day-to-day usage service data of customers.

Episode 328: ZK on Bitcoin with Alpen Labs

In this week’s episode, Anna and Tarun chat with Sims Gautam and Liam Eagen from Alpen Labs. They dive into the world of Bitcoin L2s and focus on how ZK can be used to incorporate strong connections between Bitcoin and new execution environments. The group then explores BitVM, covenants, the distinction between the Bridge Operators and sequencers in this model and how this differs from how these actors work in Eth L2s. They then dive into SNARKnado, including what is happening under the hood, the ways in which this system offers round-based fraud games mixed with ZK and which agent provides DA and more.

Episode 327: Proof Aggregation with Shumo and Yi from NEBRA

In this week’s episode Anna chats with Shumo and Yi from NEBRA. They discuss NEBRA UPA, their Universal Proof Aggregation product. They cover what it takes to incorporate proving systems into NEBRA UPA as well as the benefits that these systems will bring, how developers are meant to interact with them, and future integrations to enable seamless cross-zkRollup applications. They cover prover marketplaces, verification aggregation systems, and the design space that these systems open up.

Bonus: ZK Hack Montreal!

Episode 326: MPC & ZK in Ligero and Ligetron

In this week’s episode Anna and Kobi chat with Muthu Venkitasubramaniam and Carmit Hazay from Ligero. They discuss their work on MPC and ZK for the last 20 years and how the research has evolved. They then dive into a nuanced conversation on how MPC & ZK are interrelated. The discuss Ligero, what led to the project and the early phases, as well as the new Ligetron system and how they plan on getting this technology into the wild.

Episode 325: Web Proofs with Tracy from Pluto

In this week’s episode Anna chats with Tracy Livengood, co-founder of Pluto; an applied cryptography org building developer tools which add verifiable data from web data to an on-chain application, using ZK.

They discuss Tracy’s move from being an engineer in Web2, what prompted his move into the decentralized web and how he eventually found his way into the ZK space. He shares the concept of ‘Web Proofs’, and how Pluto can use some of the TLSNotary stack to bring private web data into on-chain applications, as well as a future tool set he hopes to develop with the project.

Episode 324: Discovering New Elliptic Curves with Antonio Sanso and Youssef El Housni

This week, Anna and Nico catch up with Antonio Sanso, Researcher at the Ethereum Foundation and Youssef El Housni, Engineer at ConsenSys and builder of Linea.

They discuss Antonio and Youssef’s new work, Families of prime-order endomorphism-equipped embedded curves on pairing-friendly curves, and dive into Elliptic Curve cryptography, Bandersnatch and Verkle Tries amongst much more, before dissecting what terms in the title of this paper truly mean. After getting into the weeds of cryptographic technicalities, the group explores where this work could be used and what it would enable.

Episode 323: The Role of Reth with Georgios

This week, Anna and Tarun catch up with Georgios Konstantopoulos, CTO of Paradigm and long-standing friend of the ZK Pod!

First they cover the work Georgios has been doing since he last appeared on the show, covering everything from updates on Foundry to the more recent work on Reth. They then dig into what makes it different, what inspires its design, where it is heading and the eventual end goals of the project. They also chat about the general client node landscape, from the ETH 2.0 research days to present day, before diving into discussing different clients from different teams, how this diversity can protect a chain and how each client can differ.

Episode 322: Definitions, Security and Sumcheck in ZK Systems with Justin Thaler

In this week’s episode, Anna and Guillermo catch up with Justin Thaler, Associate Professor at Georgetown and Research Partner at a16z.

The group dive into a handful of points from Justin’s ‘17 Misconceptions about SNARKs’ article, discussing if his views have changed since it was published back in 2023 and whether some points have become common knowledge since the article first rippled through the ZK community. They then dive into his new zkVM Jolt, which was initially described along with Lasso in 2023, but has now been implemented and is open to contributions from the community.
