Proof Aggregation

Definition ∞ Proof Aggregation is a cryptographic technique used to combine multiple individual proofs into a single, more compact proof. This process significantly reduces the verification overhead required for a large set of claims or transactions, making systems more efficient. It is particularly relevant in blockchain technology for improving scalability and reducing the computational burden on network validators.
Context ∞ The implementation of Proof Aggregation techniques is a key area of research and development for enhancing blockchain scalability and reducing transaction costs. Discussions often revolve around the trade-offs between different aggregation schemes, such as SNARK aggregation and STARK aggregation, in terms of proof size, generation time, and security assumptions. The successful deployment of these methods is seen as critical for enabling more complex decentralized applications and wider network adoption.
