Multi-Round Aggregation

Definition ∞ Multi-round aggregation is a process where data or computations are combined across several distinct steps or iterations to produce a final, consolidated result. In cryptographic contexts, this often involves iteratively combining proofs or commitments from multiple parties or transactions into a single, compact proof. This method significantly reduces the amount of data that needs to be stored or verified on a blockchain. It enhances efficiency and scalability.
Context ∞ News frequently reports on multi-round aggregation in the context of scaling solutions like rollups and zero-knowledge proof systems. These technologies leverage iterative aggregation to bundle numerous off-chain transactions into a single on-chain proof. Monitoring advancements in multi-round aggregation helps in understanding how blockchains are improving transaction throughput and reducing verification costs, thereby addressing network congestion challenges.
