#以太坊L2如何发展？ L2 is Cooling Off? Vitalik Changes Tune After Reversal, the Deadlock of Ethereum L2's Fate
On February 3, 2026, Ethereum co-founder Vitalik Buterin changed his long-held view that Layer-2 is the primary way to scale Ethereum, stating that this approach "no longer makes sense."
Vitalik's remarks clearly put L2 at a crossroads—what does the future hold for L2?
1. L2 at the Crossroads
Layer-2 aims to participate in "Ethereum scaling" by creating block space fully protected by the Ethereum mainnet. In this block space, all transactions are valid, censorship-resistant, and final, but ma

L2 is not about scalability; it's about "division of labor."
Many people understand Ethereum L2 as a "scalability tool," but a more accurate description is that it is reconstructing the division of labor system. L1 is responsible for security and settlement, while L2 handles execution and user experience. This is like transforming a congested one-way street into a city traffic network of "main roads + overpasses + side streets."
The maturity of Rollup technology allows transactions to be efficiently executed off-chain, with the results compressed and submitted to the main chain for verificatio

L2 Competition Will Ultimately Return to the "Liquidity Battle"
Technology is just the entry ticket; liquidity is the real game-changer. Currently, multiple L2s are vying for market share, essentially competing for user assets and protocol deployment.
Why do many L2s have incentive programs? Because early-stage ecosystems need to kickstart with subsidies to attract liquidity. The question is: after the subsidies fade, who will retain genuine users?
The future winning L2s often possess three key traits:
1️⃣ Deep integration with mainstream protocols
2️⃣ Low cross-chain asset transfer co

The ultimate fate of L2 might be "invisible existence"
When infrastructure becomes sufficiently mature, people often don't perceive it. TCP/IP is not discussed by the general public, but the internet cannot do without it. The same may be true for L2 in the future.
Ideally, users only see the app and don't care about the chain. Wallets automatically select the optimal L2 to execute transactions, handling settlement and data submission in the background. L2 becomes the default layer, rather than an option.
This means the competition will shift toward: developer experience, SDK tools, account abs

L2 is not a panacea
Although the prospects for L2 are broad, challenges are equally real.
First is the difference in security models. Different Rollup solutions make trade-offs between data availability and verification mechanisms, making it difficult for ordinary users to assess risks. If a bridge or verification system encounters issues, the impact could be significant.
Second is governance issues. Some L2s still carry a strong centralized flavor, with upgrade permissions held by a few teams. This is beneficial for efficiency in the early stages but needs to be gradually decentralized in the
