Vitalik Buterin: Copy-Paste L2s Are Hurting Ethereum’s Progress

Ethereum co-founder Vitalik Buterin has mentioned that many new Layer 2 (L2) networks are repeating shallow design patterns, and warned that generic EVM chains with optimistic bridges are holding again significant progress.

His feedback prolong the general public debate over whether or not right this moment’s L2 ecosystem nonetheless aligns with Ethereum’s unique scaling targets.

No More “Copypasta” EVM Chains

In a February 5 put up on X, Buterin argued that consolation and familiarity, not technical necessity, are driving many L2 launches, resulting in copy-paste designs that add little past surface-level Ethereum compatibility.

The developer drew a comparability between infrastructure decisions and governance habits, writing that making yet one more EVM chain and including “an optimistic bridge to Ethereum with a one-week delay” has grow to be routine in the identical means forking Compound as soon as dominated DAO governance.

“That’s one thing we’ve achieved far an excessive amount of for much too lengthy, as a result of we received snug, and which has sapped our creativeness and put us in a lifeless finish,” Buterin wrote.

He was much more direct about different designs that drop Ethereum bridges fully.

“If you make an EVM chain with out an optimistic bridge to Ethereum, that’s even worse,” he mentioned, including, “We don’t friggin want extra copypasta EVM chains, and we undoubtedly don’t want much more L1s.”

Buterin insisted that Ethereum’s base layer is already scaling and can proceed so as to add EVM block area by means of 2026, although not with out limits. He famous that some workloads, reminiscent of AI-related purposes, should require decrease latency or specialised execution environments. In his view, these wants ought to push builders towards genuinely new architectures reasonably than flippantly modified replicas.

Matching “Vibes” With Real Ethereum Connection

Buterin’s criticism builds on feedback he made earlier, suggesting many L2s not meet the unique definition of scaling Ethereum as a result of they fail to totally inherit its safety.

He argued that Ethereum not wants L2s to behave as branded shards, particularly contemplating mainnet charges are falling and gasoline limits are rising.

In his newest put up, the 32-year-old pressured that public positioning ought to mirror technical actuality. “Vibes must match substance,” he wrote, criticizing initiatives that market themselves as tightly linked to Ethereum whereas treating that hyperlink as an afterthought.

The blockchain’s co-founder outlined two fashions he considers cheap. One is an app chain that relies upon deeply on Ethereum, reminiscent of prediction markets that settle and handle accounts on the L1 whereas dealing with execution on a rollup. The different is what he known as “institutional L2s,” the place techniques like authorities registries publish cryptographic proofs on-chain for transparency, even when they don’t seem to be trustless or credibly impartial.

“If you’re the very first thing, it’s legitimate and nice to name your self an Ethereum software,” Buterin mentioned. “If you’re the second factor, then you definitely’re not Ethereum… so it’s best to simply say these issues straight.”
