Vitalik Buterin is signaling a significant reframing of Ethereum’s layer-2 narrative: not the dying of rollups, however the finish of the concept L2s are shards whose main job is scaling the community. With L1 charges now low and fuel restrict projected to rise sharply in 2026, he argues the rollup-centric roadmap’s authentic premise now not matches the truth on the bottom.
Buterin opened his X post on Feb. 3 by pointing to 2 pressures which have been constructing in parallel: L2s have moved to “stage 2” much more slowly than anticipated, and Ethereum mainnet is scaling in its personal proper. In his telling, these developments break the outdated psychological mannequin in each instructions.
“Ethereum needs to scale,” he wrote, recapping what he framed as the unique thesis. “The definition of ‘Ethereum scaling’ is the existence of large quantities of block space that is backed by the full faith and credit of Ethereum… block space where, if you do things (including with ETH) inside that block space, your activities are guaranteed to be valid, uncensored, unreverted, untouched, as long as Ethereum itself functions. If you create a 10000 TPS EVM where its connection to L1 is mediated by a multisig bridge, then you are not scaling Ethereum.”
The punchline is blunt: “This vision no longer makes sense.” Buterin says L1 doesn’t want L2s to function “branded shards” if base-layer capability is increasing, and he’s more and more skeptical that many L2s both can or need to meet the safety and management expectations that label implies. He pointed to a minimum of one L2 that, in his phrases, “may never want to go beyond stage 1,” citing not solely technical considerations round ZK-EVM safety but in addition customer-driven regulatory necessities that “require them to have ultimate control.”
Ethereum Layer-2’s Need To Change
That’s not introduced as an indictment a lot as a categorization shift. If an L2 retains final management, it could nonetheless be a legitimate product for its customers, Buterin instructed, but it surely shouldn’t be marketed as “scaling Ethereum” within the strict sense envisioned by the rollup-centric roadmap. In that context, he argues, “we should stop thinking about L2s as literally being ‘branded shards’, with the social status and responsibilities that this entails.”
Instead, he sketches a spectrum mannequin: some L2s will be tightly backed by ETH’s safety ensures, whereas others will be looser and extra optionally available relying on person wants. That spectrum framing implicitly makes room for app-specific chains, completely different belief fashions, and non-EVM environments—with out forcing them right into a single “rollup as shard” storyline.
For L2 groups, Buterin’s steering is simple: cease anchoring your id on scaling alone. If you’re dealing with ETH or Ethereum-issued property, he argues “stage 1 at the minimum” issues; in any other case, you’re successfully working as “just a separate L1 with a bridge.” The actual differentiator, in his view, must be options and properties {that a} bigger L1 nonetheless received’t present—whether or not that’s specialised execution environments, privateness, sequencing traits like ultra-low latency, or non-financial use circumstances.
Buterin says he’s turn out to be “more convinced of the value of the native rollup precompile,” particularly as soon as Ethereum has enshrined the ZK-EVM proof verification it “need[s] anyway to scale L1.” The thought is a protocol-level precompile that verifies ZK-EVM proofs and is handled as a part of Ethereum itself, that means it will “auto-upgrade along with Ethereum,” and if it shipped with a bug, “Ethereum will hard-fork to fix the bug.”
That final level is the subtext: he desires a path the place trustless verification and interoperability are simpler to realize and not using a “security council,” and the place rollups can add customized options whereas nonetheless anchoring their EVM correctness on to Ethereum. He additionally tied this route to the prospect of synchronous composability: transactions that may safely span L1 and L2 liquidity with tight coupling, referencing ongoing analysis on combining preconfirmations with based mostly rollups and real-time proving.
Buterin’s conclusion leaves room for uncomfortable outcomes. A permissionless ecosystem will produce chains with “trust-dependent, or backdoored, or otherwise insecure” parts, he wrote, calling that “unavoidable.” The job, as he frames it, is to make ensures legible to customers whereas strengthening Ethereum’s base layer, suggesting that the subsequent section of L2 competitors could also be much less about who “scales Ethereum,” and extra about who can credibly outline, and show, what they’re truly providing.
At press time, ETH traded at $2,256.
