F* is proof-oriented programming without a narrow domain
The F* project presents a language for writing programs together with machine-checkable proofs of their properties.
F* is a general-purpose, proof-oriented language: code can carry specifications that a verifier checks. Its appeal is not replacing ordinary programming, but making high-assurance pieces of a system expressible in the same development workflow.
Programs with claims attached
The F* project describes a general-purpose language designed for verification. Developers state properties alongside code, then use its tooling to check that an implementation meets the specification under the model being used.
The boundary is where it becomes useful
Formal methods are most persuasive when failure is expensive: cryptography, protocol components, parsers, or other code with sharply defined invariants. F* is a reminder that proof-oriented programming is not only an academic exercise; it is a way to make selected assumptions executable and reviewable.
