Fiat-Shamir Bugs: How One Missing Line Breaks a Proof System
This blog post looks at Fiat-Shamir from a practical security perspective: it explains why something that seems simple in theory can become surprisingly easy to get wrong. By using vulnerabilities found in real-world projects, we give developers and reviewers a better way to think about Fiat-Shamir when designing, implementing, and auditing proof systems.
Better Codes - and how they can be worse if you're not careful
An exploration of how an AI tried to work around a security feature to handle a theorem that was hard to prove.
The Year Finding and Exploiting Bugs Became Cheap, and What to Do About It
The economics of security have changed. AI has made finding and exploiting bugs cheaper, including in cryptographic and zero-knowledge code, while validation and remediation remain slow. Here is our view of what happened, what comes next, and how teams should change the way they secure their stack to defend against AI-assisted attackers.

Common Circom Pitfalls and How to Dodge Them, Part 1
Programming in Circom comes with its fair share of challenges. After reviewing numerous Circom codebases, we’ve identified certain anti-patterns that occur frequently. In this series, we’ll provide a comprehensive overview of these issues to help you avoid the most common pitfalls. Of course, this won’t be a complete list of every mistake possible (Circom has plenty of ways to trip you up). But the footguns we’ll cover are the ones that tend to catch developers off guard the most.
