Buterin argued that many Layer 2s now not meaningfully inherit Ethereum safety.
Ethereum co-founder Vitalik Buterin mentioned latest developments imply the unique conception of Layer 2 scaling throughout the ETH ecosystem is now not viable.
He mentioned that the progress amongst many L2 networks has fallen wanting earlier expectations, whereas the mainnet continues to scale instantly.
Gradual Progress, Low Charges
In a latest submit on X, Buterin pointed to 2 necessary realities reshaping the talk. First, there’s the gradual and tough progress of L2s towards “stage 2” decentralization and interoperability, and the truth that Ethereum’s mainnet has already achieved very low charges, with gasoline limits anticipated to rise considerably by 2026.
Buterin reiterated that Ethereum scaling was initially outlined as increasing block house that totally inherits Ethereum’s safety. Which means that all exercise stays legitimate and censorship-resistant so long as the community operates. As such, techniques that depend on multisig bridges or different types of discretionary management can’t be thought of extensions of Ethereum on this sense, even when they provide excessive throughput.
The co-founder defined that this framing now not holds as a result of the blockchain now not wants L2s to perform as “branded shards,” whereas many L2s are both unable or unwilling to fulfill the safety and governance necessities that such a task would indicate.
Buterin noticed that some initiatives have explicitly said they could by no means transfer past stage 1, not solely resulting from technical issues round zero-knowledge EVM security, but additionally as a result of regulatory or buyer necessities necessitate final management. Whereas he mentioned this can be applicable for these initiatives’ use circumstances, it means they shouldn’t be described as scaling Ethereum underneath the unique definition.
As a substitute, Buterin prompt abandoning the concept all Layer 2s ought to occupy the identical class and be judged by the identical standards. He proposed that they be seen as a broad spectrum of techniques with various levels of connection to Ethereum. On this framing, some L2s could also be totally backed by Ethereum’s safety whereas others function with extra restricted ensures. This could permit customers and purposes to decide on based mostly on their wants.

He added that L2s ought to deal with offering distinct worth past generic scaling, equivalent to specialised digital machines, application-specific effectivity, excessive throughput, non-financial use circumstances, low-latency sequencing, or built-in providers like oracles or dispute decision. For networks dealing with ETH or Ethereum-issued belongings, he mentioned reaching not less than stage 1 must be a minimal normal.
ZK-EVM Precompile
From Ethereum’s perspective, Buterin mentioned he has develop into more and more satisfied of the significance of a local rollup precompile that will confirm ZK-EVM proofs as a part of Ethereum itself. Such a system in place permits trustless interoperability and composability whereas permitting L2s flexibility in extending performance.
He mentioned that whereas a permissionless ecosystem will inevitably embrace techniques with weaker or trust-dependent ensures, Ethereum’s duty is to make these ensures clear and proceed strengthening the bottom protocol.
