Definition ∞ A Fast SNARK is a type of Succinct Non-interactive ARgument of Knowledge (SNARK) that offers significantly reduced proof generation times compared to earlier iterations. SNARKs are cryptographic proofs enabling one party to verify computations performed by another without re-executing them. The “fast” attribute specifically refers to optimizations that improve the computational efficiency of creating these proofs.
Context ∞ Fast SNARKs are a pivotal development for enhancing the scalability and privacy of blockchain networks, particularly in layer-2 solutions and zero-knowledge rollups. Their improved performance enables more practical and widespread adoption of privacy-preserving technologies and efficient off-chain computation verification. News often highlights advancements in SNARK technology as key to addressing blockchain’s current limitations in throughput and transaction costs.
