EUVD-2025-199528

Inside Track / Entropy Derby is a research-grade horse-racing betting engine. Prior to commit 2d38d2f, the VDF-based timelock encryption system fails to enforce sequential delay against the betting operator. Bettors pre-compute the entire Wesolowski VDF and include vdfOutputHex in their encrypted...

On Isogenies Verifiable Delay Functions (VDF)

This continues the post frompart 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...

On Verifiable Delay Functions - How to Slow Burning the Planet Down (Verifiably)

Update: you can find the Part II of this series here In this blog post I am going to talk about some really cool cryptographic research done by Luca De Feo, Simon Masson, Christophe Petit and myself around a relatively new cryptographic construction called Verifiable Delay Functions VDF from now...
