Vitalik Buterin Says L2s That Only Copy Ethereum Make No Sense

High attention and emotional sentiment detected.

Vitalik’s Remarks at Hong Kong Web3 Festival

Vitalik made these comments during a public talk at the Hong Kong Web3 Festival. (Add source link here: official event page, video, or transcript) He said, “Layer 2s that just copy Ethereum and offer slightly cheaper or faster transactions make no sense.”

He also criticized the earlier idea of L2s acting as simple “branded shards” for scaling Ethereum. He argued this approach is less relevant today. Ethereum has already improved its base layer performance. Instead, he stressed that valuable L2s should focus on unique off chain components. These include privacy features, specialized execution environments, and application specific designs that Ethereum cannot easily support.

Generic L2s vs Valuable L2s

How Ethereum L1 Progress Changed Vitalik’s Position

Vitalik was an early advocate of the rollup centric roadmap. This approach encouraged many teams to build Ethereum compatible Layer 2s. He now suggests that simply replicating Ethereum at Layer 2 is no longer enough. This reflects changes in Ethereum’s base layer capabilities rather than a complete shift in direction.

During the same talk, he highlighted the importance of PeerDAS and improved data availability. These upgrades will shape how L2s scale in the future. He added that success will depend less on transaction speed. Instead, it will depend on building specialized environments such as privacy focused or application specific chains. These systems should complement Ethereum rather than compete with it.

What to Watch Next

• How major Layer 2 teams (Arbitrum, Optimism, Base, zkSync, etc.) publicly respond to Vitalik’s criticism and whether they adjust their roadmaps.
• Emergence of genuinely differentiated L2s especially those focusing on privacy, specialized execution environments, or unique application-specific features.
• Shifts in TVL, user activity, and developer interest toward more innovative L2s versus generic “Ethereum copies.”
• Progress on Ethereum Layer 1 scaling upgrades (PeerDAS, single-slot finality, etc.) and how they influence the future role of Layer 2s.

Conclusion

Vitalik’s comments highlight growing pressure on Layer 2 projects to move beyond simple scaling solutions. The next phase of Ethereum’s ecosystem will likely favor L2s that introduce new capabilities rather than replicate existing ones.
