ZK-Circuits

Definition ∞ ZK-Circuits, or Zero-Knowledge Circuits, are cryptographic constructs used in zero-knowledge proofs. They enable a prover to demonstrate the truth of a statement to a verifier without revealing any information beyond the statement’s validity itself. These circuits are fundamental to advanced privacy-preserving technologies.
Context ∞ Discussions surrounding ZK-Circuits in cryptocurrency news are primarily linked to advancements in scalability solutions (like ZK-rollups) and privacy-enhancing technologies. News reports often detail the development of new ZK-circuit designs that improve transaction throughput, reduce verification costs, or offer enhanced privacy features for blockchain applications. The sophistication and efficiency of these circuits are critical factors in the adoption and performance of next-generation blockchain protocols.
