In this week’s episode, Anna and Brendan Farmer catch up with Ben Fisch, CEO of Espresso Systems. They explore the inner workings of the current L2 sequencing landscape and then discuss how a shared sequencing marketplace like Espresso works. They touch on how MEV plays a part in the new system, how the role of the sequencer can be separated into subroles, how all these parts will work together in such a system and much more.

In this week’s episode, Anna catches up with Jordi Baylina, OG Ethereum contributor and Polygon zkEVM Technical Lead. They cover what Jordi has been working on since he was last on the show in 2021. Back then, zkEVMs were still just an idea. Now that many of these systems have launched, they have a chance to look at how these fit into the general L2 landscape.


They cover Jordi’s view on engineering decentralized systems and how these are rolled out, and the recent research from Polygon, including their AggLayer proposal. They wrap up on what inspires him to keep contributing in the space.

In this week’s episode, Anna and Nico chat with Chelsea Komlo, Chief Scientist for the Zcash Foundation and member of the Cryptography, Security, and Privacy lab at the University of Waterloo.


They discuss what sparked Chelsea’s interest in cryptography research, starting with her work contributing to Tor, to her move to Zcash and her PhD work on Threshold Signature Schemes. They define some important terms around different signature schemes and discuss possible optimizations that can be used to make these more performant. They then dive into her work on the FROST Threshold Signature Scheme plus some new upcoming work.
