Get Started with Lean Proof Assistant
Lean is an open-source programming language and proof assistant designed for creating correct and maintainable code. It features powerful automation tools like 'Grind' for efficient theorem proving and supports extensive metaprogramming capabilities. Lean is utilized in various verification projects, demonstrating its effectiveness in both academic and industrial applications.
- ▪Lean enables the creation of formally verified code through its proof assistant capabilities.
- ▪The 'Grind' tool automates complex theorem proving tasks, making it easier to manage intricate mathematical proofs.
- ▪Lean is used in real-world verification projects, such as AWS's Cedar authorization policy language and Rust program verification.
