Introduction
Ethereum has long been the backbone of decentralized applications and smart contracts. However, as the network navigates scalability challenges, the conversation around Layer 1 and Layer 2 solutions is shifting. Vitalik Buterin, co-founder of Ethereum, has brought renewed focus to this topic by calling into question the effectiveness of Layer 2 scaling through rollups. This article delves into the recent developments, balancing the merits and roles of both Layer 1 and Layer 2 solutions.
Understanding Layer 1 and Layer 2
What is Layer 1?
Layer 1 solutions refer to the base blockchain itself. For Ethereum, these consist of the underlying protocols, smart contracts, and network rules that govern transactions and security. Recent updates, such as EIP-7825, have significantly improved Ethereum’s core capabilities.
What is Layer 2?
Layer 2 solutions are built on top of Layer 1 and aim to enhance transaction speed and scalability by taking some workloads off-chain. Notable Layer 2 platforms include Optimism and Arbitrum, which strive to reduce gas fees and enhance transaction throughput.
Vitalik Buterin’s Insights on Layer 2 Decentralization
On February 3, 2026, Vitalik Buterin indicated that the decentralized growth of Layer 2 solutions has lagged behind expectations. Out of more than 50 major Layer 2 projects examined, only two had reached a sufficient level of decentralization by early 2026, as per data from L2Beat. This stagnation prompted Buterin to rethink the Ethereum scalability strategy, suggesting an increased focus on enhancing Layer 1 capabilities.
The Performance of Layer 1 Solutions
Thanks to recent upgrades, Ethereum’s Layer 1 can straightforwardly handle 20-30 transactions per second (TPS) while maintaining fees under 2 gwei. The planned increase of the gas limit to 50 million permits a more efficient allocation of block space, facilitating an enhanced user experience. This carefully orchestrated scaling demonstrates that Layer 1 is capable of supporting a more extensive user base and heavier workloads than previously anticipated.
| Improvement Measure | TPS Capacity | Fee per Transaction |
|---|---|---|
| Current Capacity | 20-30 TPS | < 2 gwei |
| Planned Gas Limit | 50 million |
The Evolving Role of Layer 2 Projects
As Ethereum’s focus shifts back to Layer 1, Layer 2 platforms must pivot from basic scaling functions to more advanced applications. Buterin has suggested potential innovations for Layer 2 solutions, including:
- Privacy Enhancements
- Low-latency Transaction Sequencing
- Non-EVM (Ethereum Virtual Machine) Virtual Machines
This shift proposes a hybrid ecosystem where Layer 1 solutions provide robust security while Layer 2 focuses on delivering specialized functionalities.
The New Paradigm of Ethereum Scaling
The current trajectory of Ethereum emphasizes a greater role for Layer 1 upgrades in achieving scalability. While Layer 2 remains vital, its responsibilities may evolve to support advanced features rather than simply offloading transactions. Balancing these two layers not only promises increased throughput but also enhances security.
By focusing on a comprehensive strategy that unifies both layers, Ethereum is set to improve user experience and achieve higher scalability without excessive reliance on Layer 2 rollups.
| Aspect | Layer 1 | Layer 2 |
|---|---|---|
| Security | Strong base layer | Dependent on Layer 1 security |
| Transaction Speed | Growing capacity | Currently high but under scrutiny |
| Use Cases | Basic transactions | Advanced applications and features |
Conclusion
The evolution of Ethereum’s scaling strategy, as articulated by Vitalik Buterin, heralds significant changes in how the blockchain will operate. By focusing on Layer 1 enhancements and redefining Layer 2’s role, Ethereum aims to provide a more unified, efficient, and secure framework that can better accommodate users and developers in an increasingly complex decentralized landscape.
