Vitalik Buterin suggests a major reconfiguration of Ethereum’s Layer 2 story. It isn’t the demise of rollups, however the finish of the concept that L2 is a shard whose main position is to scale the community. With L1 tariffs at present low and fuel limits anticipated to rise sharply in 2026, he argues that the unique assumptions of the roll-up-centric roadmap not match the truth on the bottom.
Buterin opened his X-Put up on February 3, pointing to 2 parallel pressures. L2 is transferring into “Stage 2” far more slowly than anticipated, and Ethereum’s mainnet is increasing by itself. He says these developments problem outdated psychological fashions in each instructions.
“Ethereum must scale,” he wrote, summarizing what he had framed as his preliminary principle. “The definition of ‘scaling Ethereum’ is the existence of a considerable amount of block area backed by the total belief and confidence of Ethereum… In block area, once you do one thing inside that block area (together with ETH), that exercise is assured to be legitimate, uncensored, unreverted, and untouched for so long as Ethereum itself capabilities. 10000 the place the connection to L1 is mediated by a multisig bridge Creating an EVM for TPS doesn’t scale Ethereum.
The punchline is simple: “This imaginative and prescient not is smart.” Buterin mentioned L1 does not want L2 to behave as a “branded shard” if base layer capability is rising, and lots of are more and more skeptical that L2 can or needs to fulfill the safety and management expectations that the label implies. He cited technical issues concerning the security of ZK-EVM, in addition to customer-driven regulatory necessities that “demand final management,” and pointed to at the very least one L2 that, in his phrases, “could by no means wish to transcend Stage 1.”
The necessity for modifications to Ethereum Layer 2
It’s introduced not as an accusation however as a change in classification. Buterin instructed that if L2 retains final management, it might nonetheless be a viable product for customers, but it surely shouldn’t be bought as “scaling Ethereum” within the strict sense envisioned by its rollup-centric roadmap. In that context, he argues, “We should always cease considering of L2 as actually a ‘branded shard’ with related social standing and tasks.”
As an alternative, he sketches a spectral mannequin. Some L2s are strictly backed by ETH’s safety ensures, whereas others may be extra relaxed and non-compulsory relying on the person’s wants. This spectral framing implicitly permits area for app-specific chains, totally different belief fashions, and non-EVM environments with out forcing them right into a single “roll up as shards” storyline.
For L2 groups, Buterin’s steering is simple. Do not pin your identification solely on scaling. If you’re coping with ETH or Ethereum issued belongings, he argues that “minimal Stage 1” is essential. In any other case, it’ll successfully act as “only a separate L1 with a bridge.” In his view, the true differentiators must be options and traits that large-scale L1s can not but supply, akin to specialised execution environments, privateness, sequence traits akin to ultra-low latency, or non-financial use instances.
Buterin mentioned he has grow to be “extra satisfied of the worth of native rollup precompilation,” particularly since Ethereum launched ZK-EVM proof verification, as a result of “we have to prolong L1 anyway.” The thought is a protocol-level precompilation that verifies ZK-EVM proofs and is handled as a part of Ethereum itself. Which means that it’ll “auto-upgrade together with Ethereum,” and if it ships with a bug, it signifies that “Ethereum will laborious fork to repair the bug.”
This final level is the subtext. He wish to see a path the place trustless validation and interoperability may be simply achieved and not using a “safety council” and the place customized performance may be added in rollups whereas pinning EVM correctness on to Ethereum. He additionally talked about ongoing analysis on tying this course with the prospect of synchronous composability, transactions that may safely straddle L1 and L2 liquidity in a tightly coupled method, combining pre-checks with base rollups and real-time proofs.
Buterin’s conclusions go away room for disagreeable penalties. A permissionless ecosystem would create a sequence with “belief dependencies, backdoors, and different insecure” components which can be “inevitable,” he wrote. The job, as he frames it, is to offer readable ensures to customers whereas strengthening Ethereum’s base layer, suggesting that the subsequent stage of the L2 race might not be about who will “scale Ethereum,” however who can reliably outline and show what they’re truly providing.
On the time of writing, ETH was buying and selling at $2,256.
