Computational Soundness

Definition ∞ Computational soundness refers to the assurance that a cryptographic proof system correctly verifies computations. This property confirms that if a statement is true, a valid proof can be generated and successfully verified. It also means no false statement can ever be proven true within the system. It is a critical attribute ensuring the integrity and reliability of zero-knowledge proofs and other advanced cryptographic protocols.
Context ∞ The relevance of computational soundness is growing significantly within blockchain technology, particularly with the rise of zero-knowledge rollups and other scaling solutions. Developers and researchers are continuously working to construct more efficient proof systems that maintain robust soundness guarantees. This is vital for securing decentralized applications and improving transaction throughput without sacrificing security. Ongoing research aims to optimize proof generation and verification while upholding these foundational cryptographic properties.
