Hyperproperty Preservation

Definition ∞ Hyperproperty Preservation refers to the maintenance of complex security or privacy characteristics across multiple execution paths or states of a system. It is a formal concept in computer science ensuring that properties relating to the entire behavior of a system remain intact. This ensures that even under varying conditions, certain critical security attributes are consistently upheld. It goes beyond simple state-based properties.
Context ∞ Hyperproperty preservation is a highly specialized topic within advanced blockchain security and privacy research. While not frequently in mainstream news, it underpins the theoretical security of zero-knowledge proofs and privacy-preserving smart contracts. Discussions among experts concern its application to verify the non-leakage of sensitive information or the integrity of complex decentralized protocols.
