Provably Secure

Definition ∞ A system or cryptographic primitive is considered provably secure if its security properties can be mathematically demonstrated under specific, well-defined assumptions. This involves formal proofs that show the system resists certain types of attacks, often by reducing its security to a known hard problem. It offers a high level of assurance regarding its robustness. This mathematical certainty is a significant security attribute.
Context ∞ The concept of provable security is paramount in the design and analysis of new blockchain protocols and cryptographic algorithms. While no system is absolutely invulnerable, formal proofs provide strong guarantees against known attack vectors. News regarding new consensus mechanisms or cryptographic techniques often highlights their provable security claims, reinforcing trust in their design.
