  • Sergey Gorbunov on TEEs and the Arc Privacy Sector

    Sergey Gorbunov on TEEs and the Arc Privacy Sector
    Jul 8 2026
    This week, Anna speaks with Sergey Gorbunov, Engineer at Circle, about Arc, Circle’s new EVM-compatible Layer 1 blockchain, and its approach to a TEE based on-chain privacy. They begin by revisiting Sergey’s journey from Axelar to Circle, reflecting on the evolution of cross-chain infrastructure, the aftermath of the Terra collapse, and how Circle’s acquisition of Interop Labs led to the development of Arc. The conversation then turns to Arc’s architecture, including its privacy layer, known as the Privacy Sector, and the decision to build it around Trusted Execution Environments (TEEs) rather than ZKPs or FHE. Sergey explains the design trade-offs, discussing privacy, composability, enterprise infrastructure, and why he believes TEEs are currently the most practical foundation for programmable private execution.

  • zkMesh+ Exclusive Clip – Benedikt Bünz on the threat of AI

    zkMesh+ Exclusive Clip – Benedikt Bünz on the threat of AI
    Jul 1 2026

    Last week on the show, we interviewed Benedikt Bünz, Chief Scientist at Espresso Systems and Professor at NYU.

    The conversation ran long, so we're releasing some of the extra material as an exclusive clip for zkMesh+ subscribers. We've also included the first five minutes here. In this segment, Anna, Kobi, and Benedikt discuss whether AI poses a genuine threat to the foundations of cryptography.

    They explore the 'immune system' metaphor for AI's dual role in security: it can uncover bugs and vulnerabilities, while also strengthening defenses through tools like formal verification. The conversation closes with the question of whether AI could ever break fundamental cryptographic primitives—or even invent new physics to do it.

  • Pushing the Limits of Proof Systems with Benedikt Bünz

    Pushing the Limits of Proof Systems with Benedikt Bünz
    Jun 24 2026
    In this episode, Anna and Kobi speak with Benedikt Bünz, Chief Scientist at Espresso Systems and Professor at NYU. They start with a quick update on Espresso's architecture, its role in delivering fast finality across chains, and the challenges of building high-throughput blockchain infrastructure. The conversation then turns to Benedikt’s recent research on folding schemes, hash-based proof systems such as Arc and Warp, and Golden, a non-interactive distributed key generation protocol for threshold signatures. The episode later explores Flock, a new proof system for standard hash functions such as Blake3 and SHA-256 that exceeds Ethereum's post-quantum proving targets without relying on specialized hash functions. They conclude by discussing proof system performance, post-quantum cryptography, and the use of AI-assisted development in cryptographic engineering.
