CVE-2025-65951

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...

CVE-2025-65951

CVE-2025-65951 affects Inside Track / Entropy Derby. Before commit 2d38d2f , the VDF-based timelock encryption did not enforce sequential delay against the betting operator, enabling bettors to pre-compute the Wesolowski VDF and include the output in encrypted bets. This allowed the house to decr...

This allows bettors to pre-compu...

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...
