Formal Security

Definition ∞ ‘Formal Security’ refers to the rigorous mathematical verification of security properties within a system or protocol. It involves using formal logic and mathematical proofs to demonstrate that a system adheres to its specified security requirements under various conditions. This approach aims to provide a higher degree of assurance than traditional testing methods.
Context ∞ In the realm of digital assets and blockchain, ‘Formal Security’ is increasingly discussed in relation to smart contract auditing and protocol design. Key debates center on the feasibility and cost-effectiveness of applying formal methods to complex systems. Future developments to watch include advancements in automated verification tools and their broader adoption by development teams.
