Recursive Zero Knowledge

Definition ∞ Recursive Zero Knowledge refers to a cryptographic technique where a zero-knowledge proof can verify the correctness of another zero-knowledge proof. This allows for the creation of proofs about proofs, enabling the aggregation of many computations into a single, compact proof. It significantly reduces the computational resources needed for verification, especially in large-scale systems. This method offers a powerful way to scale verifiable computation.
Context ∞ Recursive Zero Knowledge is a cutting-edge area of cryptography with profound implications for blockchain scalability and efficiency. It is a key component in the design of next-generation layer-2 solutions and rollups, allowing for off-chain computation to be verified on-chain with minimal cost. News often reports on breakthroughs in recursive ZKP research and their implementation in new protocols. This technology is viewed as essential for overcoming current blockchain throughput limitations and enabling more complex decentralized applications.
