Dafny

Dafny is a programming language designed for writing software that can be formally verified for correctness. Think of it as a special type of coding tool where you not only write the code but also include precise rules and properties about how the code should behave. The Dafny system then automatically checks that the code adheres to these rules, ensuring it works correctly before it’s even run. This approach helps catch bugs and errors early, making software more reliable, especially in safety-critical systems like banking, aerospace, or medical devices.
