Program Verification

Definition ∞ Program verification is the process of proving that a computer program or algorithm meets its specified requirements and behaves as intended. This technique employs formal methods to mathematically confirm the correctness, security, and reliability of software. In blockchain development, it is crucial for smart contracts and core protocol logic to prevent vulnerabilities. Rigorous verification helps ensure the integrity and safety of decentralized applications.
Context ∞ News often highlights program verification in the context of smart contract audits and the security of decentralized finance (DeFi) protocols. Discussions frequently concern the complexity and resource intensity of formally verifying large codebases. A key future development involves the advancement of automated verification tools and more accessible formal methods for blockchain developers.
