Definition ∞ Proof-based security refers to cryptographic methods and protocols that provide verifiable assurances of data integrity and system behavior. These security models often rely on mathematical proofs to guarantee properties like confidentiality, authenticity, and non-repudiation. Zero-knowledge proofs are a prominent example, allowing verification without revealing underlying information. This approach enhances trust in digital interactions.
Context ∞ Proof-based security is a rapidly advancing area within blockchain technology, particularly relevant for enhancing privacy and scalability in digital assets. News often reports on new cryptographic primitives and their applications in decentralized finance and identity management. The development of more efficient proof systems contributes significantly to the security and utility of blockchain platforms. Zero-knowledge attestations are a key application.
