Could you build this?
No Formal verification of a cryptographic primitive (SHA-256) in a parallel functional language (Bend/HVM) with machine-checked proofs requires advanced formal methods expertise.
What it would actually take: This project requires writing SHA-256 in Bend and formulating formal specifications conforming to FIPS 180-4, then constructing rigorous mathematical proofs of correctness using interactive theorem provers (like Coq, Lean, or specialized verification frameworks). The hard part is proving bitwise invariants, word schedules, and compression loops without relying on runtime testing. Requires deep domain knowledge in formal methods, proof assistants, and cryptographic specifications.
