Cryspen

Congrats to Cryspen 🏆   Cryspen received the POPL Most Influential Paper Award for their paper “Dependent Types and Multi-monadic Effects in F*”. The 2016 paper presented a redesigned version of F* enabling to work both as a proof assistant as well as a general-purpose, verification-oriented, effectful programming language. Karthikeyan Bhargavan received the award together with Nikhil Swamy, Catalin Hritcu, Chantal Keller, Aseem Rastogi, Antoine Delignat-Lavaud, Simon Forest, Cédric Fournet, Pierre-Yves Strub, Markulf Kohlweiss, Jean Karim Z. and Santiago Zanella-Béguelin.   Today, F* plays a key role in Cryspen’s participation for PROTECT.     #POPL #EvIT #formalverification #trustworthyIT #cyberagentur

[🥇 Distinction] Le Most Influential Paper Award de la conférence #POPL2026 (Principles of Programming Languages) a été attribué à l’article « Dependent Types and Multi-monadic Effects in F* », co-signé par plusieurs scientifiques de l’équipe-projet PROSECCO du Centre Inria de Paris en 2016. Cette distinction récompense l’impact scientifique durable de ces travaux dans les domaines des langages de programmation et de la vérification formelle. En proposant une approche combinant types dépendants et effets multi-monadiques, l'article a contribué de manière déterminante au développement du langage F*. Ces recherches ont permis la mise en œuvre de projets dédiés à la vérification formelle de logiciels sécurisés à grande échelle. 👏 Félicitations aux auteurs, alors affiliés au Centre Inria de Paris lors de la rédaction : Catalin Hritcu (Max Planck Institute for Security and Privacy (MPI-SP), Karthikeyan Bhargavan (Cryspen), Chantal Keller (Centre Inria de Saclay), Antoine Delignat-Lavaud (Microsoft Research), Simon Forest (Centre Inria de l’Université de Lorraine), Jean Karim Z.

New blog post is live! 🦀 We used hax and F* to formally verify termination and panic freedom for a small real-world Rust crate (gcd). But that's not all—we also conducted a deep comparative analysis! We put Kani, Verus, and Aeneas to the test on the exact same code, exploring the different approaches, challenges, and proof efforts required by each tool. See how the Rust verification landscape stacks up! https://lnkd.in/dbuR29Wh

Catch Karthik, our Chief Researcher, at the European Conference on PQC Migration next week, where he will be championing the need for the EU to implement provably secure protocols and high-assurance software. See you there? 👋 📅 Dec 2-3, 2025 🔗 https://pqc-conference.eu/ #PQC #EU

We're thrilled to welcome Alexander Bentkamp to the Cryspen family! Alex joins our Tools and Proofs team with a deep background in automated and interactive theorem proving, especially with the Lean proof assistant. We're excited to have his expertise as we continue our work on formally verifying security-critical software. Welcome aboard, Alex! https://lnkd.in/ev4fubGs #Cryspen #Welcome #FormalVerification #TheoremProving
