👉 Proof engineering is a systematic approach to verifying the correctness of software systems through rigorous mathematical and formal methods. It involves designing, constructing, and validating proof systems that can automatically or semi-automatically demonstrate the correctness of software properties, such as functional equivalence, safety, and security. This process typically includes formal specification of system behavior, creation of proof assistants or automated theorem provers to construct and check proofs, and continuous refinement of these proofs based on feedback and analysis. By integrating proof engineering into the software development lifecycle, engineers can ensure that critical systems meet their specifications and operate reliably under all conditions, significantly reducing the risk of errors and enhancing overall system trustworthiness.
