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 long run.
Furthermore, from a regulatory perspective. The deployment of L2 applications may come under regulatory scrutiny sooner, especially in financial and privacy scenarios.
Another overlooked issue: Does excessive L2 adoption weaken main chain revenue? If data compression is overdone, L1 transaction fee income might decline, which requires mechanism design to balance.
Therefore, the development of L2 will not be smooth sailing but will evolve through trial and error.
A rational summary in one sentence: L2 is an expansion solution, not a universal answer.
