Scalable Rollup Design

Definition ∞ Scalable rollup design refers to the architectural and engineering principles employed in constructing rollup solutions to significantly increase the transaction processing capacity of a base blockchain. Rollups execute transactions off-chain, bundle them, and then post a compressed summary or cryptographic proof to the mainnet. This design aims to achieve high throughput and lower transaction costs while inheriting the security of the underlying layer-1 chain. It is a key approach to blockchain scaling.
Context ∞ In crypto news, scalable rollup design is a central discussion point for improving the performance of major blockchain networks, particularly Ethereum. Reports often cover the advancements in optimistic rollups and zero-knowledge (ZK) rollups, comparing their security models, proof generation times, and data availability strategies. The ongoing evolution of rollup designs is critical for supporting the mass adoption of decentralized applications and digital assets.
