Ethereum’s roadmap increasingly centered rollups for scaling
Ethereum’s scaling strategy evolved toward supporting many rollups that execute transactions while using Ethereum as a settlement and data layer.
This direction favors ecosystem diversity and specialized execution environments over forcing every application into one global execution layer.
The shift made L2 interoperability, bridging and data availability central topics for the next phase of Ethereum development.
A rollup ecosystem can scale aggregate capacity while fragmenting liquidity and user experience across networks.
