Hello everyone, I’m a PhD student (hopefully not a student for much longer) in cryptography. I’ve recently become interested in formal verification/type theory etc which brought me here.

I’m generally interested in using Lean to build dependent-typed DSLs for cryptographic applications (such as SNARKs for example). I’m interested in lean both as a theorem prover but also potentially as a somewhat more general purpose programming language for cryptographic implementations. As such, I’m very interested in learning more about writing performant code in Lean. Glad to meet you all!

Hey! Great to see more cryptographers interested in Lean.

Are you aware of https://www.hacs-workshop.org?

if you haven’t seen it, there’s ArkLib, clean, zkLean

@Wrenna Robson I am, thank you! I will be at RWC this year, so I did apply to attend this workshop

Wrenna Robson (Jan 14 2026 at 14:42):

I'll see you there

I was aware of Galois' zk dsl, but I was not aware of 'clean', that looks really interesting, thank you!

I've been contributing to the clean project for a while. There's also cryptography involving reduction proofs. I formalized a recent FRI round-by-round soundness proof (by a colleague and his coauthors) with the help of Harmonic's Aristotle: https://blog.zksecurity.xyz/posts/simple-rbr-fri/

Alas, they did not accept my self nomination, but perhaps I'll see you at RWC itself!
