Definition ∞ Recursive composition refers to building complex systems or proofs by combining smaller, self-similar components. In cryptography, particularly with zero-knowledge proofs, this technique allows for the aggregation of multiple proofs into a single, smaller proof. This significantly reduces the computational burden for verification, as a single proof can attest to the correctness of many underlying computations. It enables the creation of highly scalable and efficient verifiable systems.
Context ∞ Recursive composition is an advanced concept critical for scaling zero-knowledge proof systems and enhancing the efficiency of rollups in blockchain technology. Researchers are actively working on practical implementations to reduce proof generation times and overhead. Its successful deployment holds the potential to dramatically increase transaction throughput and privacy on decentralized networks.
