Definition ∞ Zero-overhead proving refers to the ideal scenario where generating a cryptographic proof requires negligible additional computational cost beyond the original computation itself. This concept represents a theoretical limit in zero-knowledge proof systems, aiming to minimize the computational burden on the prover while maintaining proof soundness and completeness. While truly zero overhead is unattainable in practice, research efforts focus on reducing this overhead to make complex verifiable computations economically viable. Lower overhead enables more efficient and scalable privacy-preserving applications.
Context ∞ Zero-overhead proving is a long-term research goal in advanced cryptography and blockchain scaling solutions, often discussed in academic and technical news. Current zero-knowledge proof systems still incur significant prover costs, which limits their practical application for very large computations. Continued advancements in cryptographic algorithms and hardware acceleration are directed towards approaching this theoretical ideal, which would unlock new possibilities for decentralized and private computing.
