Prover Efficiency

Definition ∞ Prover efficiency relates to the computational resources and time required to generate cryptographic proofs, particularly in systems employing zero-knowledge proofs. Higher prover efficiency means proofs can be generated more quickly and with less computational power. This metric is crucial for the scalability and practical application of advanced cryptographic techniques in blockchain technology.
Context ∞ Prover efficiency is a key performance indicator discussed in relation to scaling solutions for blockchains, such as zero-knowledge rollups. News often highlights improvements in prover algorithms or hardware acceleration that enhance this efficiency. Understanding prover efficiency is vital for assessing the technical feasibility and economic viability of systems that rely on complex cryptographic computations for security and scalability.
