Episode 117: Isogenies with Luca De Feo
February 19th, 2020 | 1 hr 23 secs
blockchain, cryptography, isogenies, math, morphisms, tech education, vdfs, verifiable delay functions
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.
