Ethereum co-founder Vitalik Buterin has sparked a meaningful conversation about the future of Ethereum’s scalability solutions. In a detailed blog post, he outlined why the long-standing approach to scaling through Layer-2 (L2) networks must evolve as Ethereum’s main network grows faster than anticipated and many L2 networks face challenges in meeting decentralization and security goals.
Why the Change in Layer-2 Vision?
Ethereum’s original roadmap envisioned Layer-2 solutions as “branded shards,” tightly integrated extensions of the Ethereum ecosystem that would inherit its robust security and censorship resistance. However, Buterin notes that this vision has not materialized, and the assumptions underpinning it have changed significantly:
- Progress on Decentralization: L2 networks have struggled to achieve full decentralization. Many developers admit they may never reach this goal due to regulatory requirements or technical challenges.
- Scaling the Base Layer: Ethereum’s mainnet is expanding its capacity, with transaction fees dropping and major upgrades planned for 2026. This lessens the reliance on L2 systems for scaling.
These factors indicate that Ethereum’s original approach to L2s as near-identical replicas “no longer makes sense,” Buterin stated. Instead, he proposes a more flexible and adaptive framework for these networks.
What’s Next for Layer-2 Networks?
Buterin suggests a new role for L2s in the Ethereum ecosystem. Rather than acting as direct extensions of Ethereum, they should emphasize unique features and functionalities. L2 networks could diversify by offering:
- Privacy tools for secure and anonymous transactions
- Ultra-fast processing for high-frequency decentralized applications
- Non-financial uses like identity management or social platforms
- Solutions for workloads beyond Ethereum’s expanded mainnet capacity
Additionally, he emphasized the importance of maintaining a minimum security integration for L2 networks that rely on Ethereum-native assets, such as Ether.
Ethereum’s Role in the Ecosystem
To support this evolving framework, Buterin expressed increased confidence in introducing a native rollup precompile capability to Ethereum’s blockchain. This feature would enable Ethereum to directly verify advanced cryptographic proofs from L2s, enhancing interoperability, trust, and security.
While this adaptability may result in some L2s being less secure or more centralized, Buterin believes this is a necessary trade-off in a permissionless ecosystem. His ultimate goal remains the same: to build the strongest and most versatile Ethereum possible.

Conclusion
Vitalik Buterin’s vision for Ethereum underscores a significant shift in its scaling narrative. The roadmap reflects a move away from uniform Layer-2 solutions toward a flexible, tailored ecosystem that adapts to Ethereum’s continuous growth. As the blockchain space evolves, Ethereum’s focus on scalability and innovation is set to redefine its role in the decentralized tech landscape.
