Ethereum co-founder Vitalik Buterin has said that many new Layer 2 (L2) networks are repeating shallow design patterns, and warned that generic EVM chains with optimistic bridges are holding back meaningful progress.
His comments extend the public debate over whether today’s L2 ecosystem still aligns with Ethereum’s original scaling goals.
No More “Copypasta” EVM Chains
In a February 5 post on X, Buterin argued that comfort and familiarity, not technical necessity, are driving many L2 launches, leading to copy-paste designs that add little beyond surface-level Ethereum compatibility.
The developer drew a comparison between infrastructure choices and governance habits, writing that making yet another EVM chain and adding “an optimistic bridge to Ethereum with a one-week delay” has become routine in the same way forking Compound once dominated DAO governance.
He was even more direct about alternative designs that drop Ethereum bridges entirely.
Buterin insisted that Ethereum’s base layer is already scaling and will continue to add EVM block space through 2026, though not without limits. He noted that some workloads, such as AI-related applications, may still require lower latency or specialized execution environments. In his view, those needs should push developers toward genuinely new architectures rather than lightly modified replicas.
Matching “Vibes” With Real Ethereum Connection
Buterin’s criticism builds on comments he made earlier, suggesting many L2s no longer meet the original definition of scaling Ethereum because they fail to fully inherit its security.

He argued that Ethereum no longer needs L2s to act as branded shards, especially considering mainnet fees are falling and gas limits are rising.
In his latest post, the 32-year-old stressed that public positioning should reflect technical reality. “Vibes need to match substance,” he wrote, criticizing projects that market themselves as tightly connected to Ethereum while treating that link as an afterthought.
The blockchain’s co-founder outlined two models he considers reasonable. One is an app chain that depends deeply on Ethereum, such as prediction markets that settle and manage accounts on the L1 while handling execution on a rollup. The other is what he called “institutional L2s,” where systems like government registries publish cryptographic proofs on-chain for transparency, even if they are not trustless or credibly neutral.
