Ethereum Founder Vitalik Buterin Calls for a Rethink of Layer-2 Networks as Base Layer Gains Momentum

Ethereum founder Vitalik Buterin has called for a fundamental reevaluation of the role of Layer-2 networks in the blockchain ecosystem. He argued that Ethereum's base layer is now scaling independently, reducing the need for L2s to serve as primary scaling solutions.

The founder pointed to two key developments: first, the slow progress of Layer-2s toward full decentralization and security. Second, the rapid improvements in Ethereum's main network capacity and reduced transaction fees.

This shift has prompted a rethinking of the original vision for L2s, which Buterin described as no longer making sense. Instead, they should be viewed as a spectrum of options with varying degrees of integration and security.

Why the Move Happened

Ethereum's core network has grown faster than anticipated, making it less reliant on Layer-2 solutions. Transaction fees have fallen sharply, and planned capacity increases for 2026 will further enhance the base layer's scalability.

Buterin also noted that some Layer-2 projects have openly stated they may never achieve full decentralization. These projects may better serve niche use cases but do not align with the broader vision of scaling Ethereum.

The original roadmap for Ethereum envisioned L2s as tightly integrated, branded shards. However, this vision has not materialised. Instead, Buterin now sees a future where L2s range from chains fully secured by Ethereum to more independent systems.
