Cryptographic Aggregation

Definition ∞ Cryptographic aggregation is a technique that combines multiple cryptographic operations or data points into a single, verifiable unit. This process aims to reduce the computational overhead and data storage requirements associated with complex cryptographic schemes. It is particularly relevant in advanced zero-knowledge proof systems and privacy-preserving technologies.
Context ∞ Current discussions on cryptographic aggregation often focus on its application in scaling solutions like zk-rollups and its potential to enhance the efficiency and privacy of blockchain transactions. The development of new aggregation techniques and their impact on transaction throughput and verification costs are significant areas of research.
