In this week’s episode, we dive into Isogenies - a topic at the cutting edge of cryptography. We look at how they are related to VDFs and randomness generation. Our guest, Luca de Feo, one of the co-inventor of SIDH, helps us get an understanding for what Isogenies - or morphisms of algebraic groups - really are.

This week, we explore the Fractal transparent SNARK construction with its authors Dev Ojha and Nick Spooner - both students of Alessandro Chiesa at UC Berkeley. In this episode, We explore how Fractal works, how it improves on some of the earlier work on Sonic and Marlin, how it borrows from but differentiates itself from STARKs, as well as what they discovered while working on this paper about recursive SNARKs and what makes that property possible.
