But as adoption surged, so did the network’s limitations. High gas fees, slow throughput, and congestion made everyday usage difficult for mainstream users. Layer 2 rollups changed everything. By moving computation off‑chain while preserving Ethereum’s security, rollups have evolved from experimental add‑ons into the primary execution layer of the Ethereum ecosystem . In 2025, more than 85% of all Ethereum ecosystem transactions now occur on L2s , while Ethereum L1 remains the settlement and liquidity backbone. Ecosystems like Base, Arbitrum, Optimism, zkSync, and StarkNet now process millions of transactions daily, support thriving DeFi and gaming ecosystems, and enable applications that would be eco...
