Vitalik Buterin explains the preferred design for Ethereum L2 solutions
Vitalik Buterin Advocates for Simplified Ethereum Layer 2 Solutions
Vitalik Buterin, Ethereum’s co-founder, is once again weighing in on the ideal blueprint for Layer 2 (L2) solutions within the Ethereum ecosystem. In a recent post on X (formerly Twitter), Buterin emphasized the importance of L2s prioritizing simplicity and leveraging the inherent security of Ethereum’s Layer 1 (L1), while minimizing unnecessary complexity.
Buterin envisions L2s primarily operating as a streamlined system focused on sequencing and proving transactions. He believes that L2s should ideally act as sequencers and provers, minimizing duplication of existing Ethereum L1 components. This approach, according to Buterin, would maximize the effectiveness of these scaling solutions without compromising the decentralized nature and robustness of the core Ethereum infrastructure.
This guidance arrives amidst discussions surrounding the migration of L1 networks, like Celo, towards Ethereum-based L2 models. This transition aims to boost efficiency, decrease inflationary pressures, reduce block times, and eliminate legacy code, ultimately simplifying the network. Furthermore, integrating within the Ethereum ecosystem grants access to its established community resources and network effects.
“The best way to build L2 is to lean on offers L1 (security, censorship, evidence, data utilize …) more, and reduce your logic in only one sequence and provider (if builder, just provider) over the core execution,” Buterin stated on X, urging developers to avoid unnecessary replication in the technical design of L2s.

Buterin further drew parallels to past attempts by various blockchain projects, arguing that while those earlier ideas may have faltered previously, they might find success now thanks to the advanced tooling and infrastructure available within the Ethereum ecosystem.
In previous discussions, Buterin has also highlighted the importance of solutions like “partly stateless nodes,” which help preserve decentralization even as computational demands increase. He has consistently emphasized the critical role of independent nodes in mitigating censorship and upholding user privacy.
Beyond scaling, Buterin has also explored the potential of zero-knowledge (zk) systems for digital identity. He noted that while these technologies offer enhanced privacy, they also introduce potential risks of coercion, a factor that warrants careful consideration.
The discussion comes as Ethereum’s native token, ETH, has seen a positive surge, climbing over 18% in the past week and reclaiming the $3,000 mark after beginning its recovery on July 9th.
