Memory Integrity Proof

Definition ∞ A Memory Integrity Proof is a cryptographic construct that verifies the correct execution of computations on data stored in memory without revealing the data itself. It ensures that a program has accessed and manipulated memory locations precisely as intended, without unauthorized modifications or errors. This proof is vital for enhancing the security and trustworthiness of computations in untrusted environments. It is a fundamental component in verifiable computing systems.
Context ∞ Memory integrity proofs are gaining prominence in the development of zero-knowledge virtual machines and confidential computing solutions within the blockchain space. Their ability to confirm computational correctness privately is a key discussion point for improving the security and privacy of smart contracts and decentralized applications. Continued research aims to optimize the efficiency and scalability of generating and verifying these proofs.
