A proof assistant and functional programming language used for formal verification, cited in the context of a proof-of-concept converting zlib to formally verified Lean code using Claude.
Signal Shot: a project to verify the Signal protocol and its Rust implementation using Lean
Lean formally verified Signal's cryptographic protocol and Rust implementation using the Aeneas translator, proving deployed crypto systems can achieve mathematical correctness guarantees.

FormalScience: Scalable Human-in-the-Loop Autoformalisation of Science with Agentic Code Generation in Lean
Agentic code generation enables scalable autoformalisation of mathematical proofs in Lean, overcoming a fundamental bottleneck in formal verification of science.
"Why not just use Lean?"
Lawrence Paulson contextualizes Lean's current prominence within 60 years of formal mathematics history (from AUTOMATH in 1968), arguing that landmark achievements like Jutting's 1977 formalization required original thinking rather than following crowd consensus.
"Why not just use Lean?"
Lean's current dominance in formalized mathematics risks eclipsing 60 years of foundational work in proof systems like AUTOMATH (1968) and HOL Light.
