L3 Rollups

Architecture

L3 Rollups represent a scaling solution built atop Layer-2 rollups, functioning as an application-specific or generalized rollup operating within the data availability layer provided by the underlying L2. This tiered structure aims to enhance transaction throughput and reduce costs beyond what’s achievable on L2s alone, leveraging the security of the base layer while optimizing for specific use cases. Consequently, they introduce a modularity that allows for customized execution environments and data structures, potentially fostering innovation in decentralized applications and financial instruments. The design necessitates careful consideration of inter-rollup communication and potential fragmentation of liquidity.
