Vitalik Buterin Calls for Ethereum L1 and Native Rollup Scaling as Layer-2 Role Shifts

On a Tuesday post on X, Ethereum co-founder Vitalik Buterin said his earlier view of layer-2 networks as the main path for scaling “no longer makes sense,” citing their limited decentralization and growing base-layer capacity. He now favors expanding Ethereum’s mainnet through gas-limit increases and native rollups, while suggesting L2s focus on specialized use cases instead of serving as the core scaling engine. Developers are already discussing raising the gas limit from 60 million to 80 million, and researcher Justin Drake has outlined a roadmap targeting 10,000 transactions per second on Ethereum over the next decade.
