Definition ∞ A proof composition scheme allows for the combination of multiple cryptographic proofs into a single, more compact proof. This technique is particularly valuable in scaling solutions for blockchains, where aggregating proofs reduces the amount of data that needs to be verified on the main chain. It enables efficient verification of a large number of computations or transactions. This method significantly enhances throughput.
Context ∞ Proof composition schemes are a critical area of research and development for zero-knowledge rollups and other layer-2 scaling solutions in blockchain networks. The objective is to achieve highly efficient aggregation of proofs, thereby lowering transaction costs and increasing network capacity. Ongoing work focuses on optimizing the cryptographic overhead and ensuring the security guarantees remain robust across multiple layers of proof aggregation.
