Verifiable Computation

Definition ∞ Verifiable computation is a cryptographic technique that allows a party to execute a computation and produce a proof that the computation was performed correctly. This proof can then be efficiently verified by another party without needing to re-execute the entire computation. It is essential for building trustless systems where computational integrity is paramount. This enables verification without direct observation of the process.
Context ∞ Verifiable computation is a cornerstone technology for scaling blockchains and enhancing privacy through zero-knowledge proofs. Current discussions focus on optimizing the efficiency and applicability of various verifiable computation schemes, such as SNARKs and STARKs. Key debates address the trade-offs between proof size, verification time, and the complexity of the computations that can be verified. Future developments are anticipated to yield more performant and versatile verifiable computation systems, significantly broadening their use in decentralized applications and secure data processing.
