I formalised and proved the correctness of Move’s new borrow checker in Lean: 39,000 lines of mechanised metatheory, produced in under a month with the help of an AI coding assistant. This post tells the story of how it went and what it means for the future of PL research.

In this post, we will show how to specify and verify imperative programs in Lean 4 using Velvet—an embedded verifier, which relies on a combination of automated symbolic and AI-assisted theorem proving techniques.

In this post, we discuss how to formalise, test, and prove the correctness of a classic distributed protocol by combining model checking, automated deductive verification, and AI-powered invariant inference in Veil, a new auto-active Lean-based verifier for distributed protocols.
