Vitalik Buterin tempers vision for ETH L2s, pushes native rollups

The Ethereum co-founder said many layer‑2s have failed to decentralize and continue to be mediated by multisig bridges instead of inheriting Ethereum’s security advantages.

Ethereum co-founder Vitalik Buterin has reversed his long-held view that layer-2s should be the primary way to scale Ethereum, saying the approach “no longer makes sense.”

“We need a new path,” Buterin said in a post to X on Tuesday, arguing that many layer-2s have failed to decentralize and that the Ethereum mainnet is now sufficiently scaling, with improvements coming from gas limit increases and soon native rollups.

Layer-2s were envisioned as extensions of Ethereum, managing most transactions at high speed and low cost while inheriting Ethereum’s security.
