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.
