Attack Surface

Definition ∞ An attack surface represents the sum of all possible points where an unauthorized user can attempt to access or extract data from a system. In digital assets, this includes smart contract code, network protocols, user interfaces, and connected third-party services. A smaller attack surface generally correlates with a higher security posture.
Context ∞ Security experts consistently assess and work to reduce the attack surface of blockchain protocols and decentralized applications. Significant efforts are directed towards formal verification of smart contracts and secure coding practices to limit vulnerabilities. Ongoing research focuses on zero-knowledge proofs and other cryptographic methods to minimize exposed data points.
