Definition ∞ Recursive proof aggregation is a cryptographic technique that combines multiple individual proofs into a single, compact proof. This consolidated proof retains the verifiability of all original proofs while significantly reducing the computational resources and storage required for verification. It is particularly valuable for scaling blockchain networks by enabling efficient validation of large transaction batches.
Context ∞ The pursuit of blockchain scalability and efficiency heavily relies on advanced cryptographic methods like recursive proof aggregation. News often highlights its implementation in layer-2 solutions and rollup technologies, as it offers a promising path towards processing a higher volume of transactions with reduced costs and faster finality.
