Recently, I saw Vitalik's comments on the Layer-2 ecosystem, and it struck a chord with many people. His core point is quite straightforward: right now, too many Layer-2 solutions are just copying and pasting—taking an EVM chain, adding an optimistic bridge, setting a one-week withdrawal delay—and then claiming to be part of the Ethereum ecosystem. These kinds of excuses are gradually losing their validity.

Vitalik used a vivid analogy, saying it's like back in the day when DeFi projects competed to copy Compound's governance mechanism—everyone repeating the same pattern instead of truly thinking about innovation. The result is an ecosystem that becomes more comfortable but also creatively exhausted. He bluntly stated: we don't need more copy-pasted EVM chains.

He specifically pointed out a phenomenon where some projects claim to be closely connected to Ethereum, but in practice, they operate as independent networks. Having a bridge alone doesn't mean you're part of Ethereum's core architecture. Vitalik emphasized that a project's marketing should match its actual technical integration. This sounds like a critique, but it's really a wake-up call.

Interestingly, he didn't completely dismiss the value of Layer-2. Vitalik is optimistic about two directions: one is highly integrated application-specific systems where Ethereum acts as the settlement, account, or verification layer; the other is institution-driven chains that submit cryptographic proofs or state commitments to Ethereum. These two modes have genuine technical synergy, not just marketing associations.

Once these comments were made, the entire Layer-2 ecosystem responded. Arbitrum's team said they should be seen as close allies of Ethereum rather than Ethereum itself; the team behind Base believes that as the base layer improves, Layer-2s need to offer more than just low fees. Projects like Polygon interpret this criticism as an opportunity for repositioning.

From the broader context, this discussion is set against the background of Ethereum fees continuing to decline and the base layer throughput improving. Plus, Bitcoin has recently stabilized above 74.43K, and US stocks and Asian markets are rebounding, with liquidity flowing into risk assets. In this environment, the positioning of Layer-2 solutions as "cheap alternatives" is being re-evaluated. The key question now is: as the mainnet itself scales, what real differentiated value can Layer-2 still provide? This question will determine who survives in the future.
