On Isogenies Verifiable Delay Functions (VDF)

This continues the post from part 1.
In the previous post we discussed about Verifiable Delay Functions. Here is a quick summary of what we discussed in the first part: We covered the definition of  Verifiable Delay Functions (VDF). We have seen a short history of how this idea slowly developed.We hinted the existence of some constructions.We described some application with an eye on the blockchain World. In this post we will switch gear and we will focus on a particular construction: the isogenies VDF (a construction defined by Luca De Feo, Simon Masson, Christophe Petit and myself). We try to keep the description as easy as possible simplifying many things, without trying not to worry too much about mathematical rigor (that risks to become mathematical rigor mortis :)), so mathematicians out there I beg your pardon! . Isoge WHAT? Isogeny based cryptography is last baby in the (cryptography) family.Below you can see a short history of isogeny based cryptography.

As matter of fact, the…
