Ethereum’s Co-Founder Calls for L2s That “Bring Something New to the Table”

Reused Layer-2 models and unclear ties to Ethereum are raising doubts about scalability, trust, and long-term relevance.

Ethereum co-founder Vitalik Buterin has raised concerns about the direction of Layer-2 development. He argued that many projects rely on similar technical designs with little variation. His remarks have reignited debate about what meaningful progress should look like for Ethereum’s next phase.

Calls Emerge for Rethinking Layer-2 Architecture on Ethereum

In a post shared on Farcaster, Buterin criticized what he sees as a habit of building near-identical Layer-2 networks. According to him, launching standard EVM-compatible chains paired with optimistic bridges has become routine.

He argued that comfort with familiar designs has limited creative thinking and pushed developers into a technical dead end. Buterin compared current Layer-2 practices to repeated forking in decentralized governance.

In his view, both trends reflect the overuse of tools that once served a purpose. The co-founder warned that copying existing models no longer addresses Ethereum’s real scaling needs.

Stronger criticism followed for projects that remove Ethereum entirely. Buterin stated that building standalone EVM chains without any bridge back to Ethereum creates even less value.

Such efforts only add more Layer-1 networks to an already crowded space. Ethereum itself continues to scale and will offer more blockspace over time, even if limits remain.

Future demand, particularly for AI applications, will still require faster execution and lower latency. Even so, he stressed that duplicating existing chains does not solve those challenges. Buterin insisted that developers should instead focus on ideas that clearly differ from existing ones.

Buterin Calls for Clearer Standards on How Layer-2s Connect to Ethereum

Buterin said projects should describe their connection to Ethereum honestly, with public claims matching how systems actually function. He noted that some networks present themselves as tightly integrated while relying only on a basic bridge. According to him, such gaps could lead to confusion and loss of trust.

He also backed app-chain designs that treat Ethereum as a core layer from the start. Prediction markets were one example, where market creation and settlement stay on Ethereum. In such setups, Layer-2 systems read Ethereum data directly, keeping strong ties to mainnet security and composability.

Another category discussed involved institutional Layer-2 systems. These could include government registries, social platforms, or games posting cryptographic proofs on-chain. While not trustless or neutral in the Ethereum sense, such systems could still offer verifiable transparency.

Buterin also called for honest positioning, saying projects deeply tied to Ethereum should present themselves as Ethereum-based applications. Projects that are more loosely aligned should explain their goals without overstating their ties.

His message ended with two simple principles. Buterin called on builders to create systems that deliver genuine new value. He also added that public claims about Ethereum alignment should reflect real technical dependence. As Layer-2 development continues to grow, those guidelines may shape how future projects earn trust within the Ethereum community.
