In this episode of the No Execution Podcast we explore  the world of intents. What are they? Why do they matter? And how do they relate to modular blockchains?We are joined by guests Chris Goes, Zaki Manian, Uma Roy, and Henry de Valence. Moderated by Nick White.

In this episode of the No Execution Podcast we explore how rollups *actually* work, if settlement is real, and if rollups are really just bridges. We are joined by guests Jon Charbonneau, Kelvin Fitcher, Toghrul Maharramov, and James Prestwich. Moderated by Nick White.
