Ethereum's recent Fusaka and Cancun upgrades have indeed brought significant benefits to Layer 2 — transaction fees have noticeably decreased, which is undoubtedly good news for the entire ecosystem. However, just as these good developments are still being digested, there are voices criticizing the fragmentation of L2 solutions. Essentially, each Layer 2 chain operates independently, with almost no interoperability between them, making user transitions across different ecosystems feel fragmented.

Some people are working on solutions to this dilemma. For example, the zero-knowledge privacy channel proposed in EIP-7503 is quite interesting — it can protect user privacy while attempting to enable smooth asset transfer across different layers. It sounds like it could improve the current user experience. However, to be honest, the technical difficulty of such cross-layer interoperability solutions is significant, and there are safety concerns that need to be addressed. Whether these solutions can be practically implemented and operate stably still depends on future validation results.

The fees have indeed decreased, but the fragmentation issue really makes people annoyed.

The lower fees are really satisfying, but the fragmentation is truly annoying. Jumping around feels like playing a jumping game.

Lower fees are great, but fragmentation really sucks L2s each do their own thing, cross-chain feels like crossing mountains and rivers, EIP-7503 sounds promising but who knows if it's reliable Honestly, we still need to wait for time to test it; don't let it just be another PPT proposal If this round succeeds, great; if not, we'll keep getting chopped up by the whales

Lower fees are great, but fragmentation is indeed a headache—each chain does its own thing. EIP-7503 sounds good, but I'm worried it might just be another PPT plan. As for cross-chain interoperability, don't rush to praise it before security is sorted out. To be honest, we still need to wait for verification; right now, it's all just castles in the air. Only when it can operate stably will it be considered a real solution; for now, it's not there yet.

So what if the fees are down? Cross-chain is still so fragmented... It's really like a slow motion with the left hand and right hand.

The fees have come down, which is quite satisfying, but the fact that each L2 is doing its own thing is really disgusting, and the cross-chain experience is terrible. EIP-7503 sounds impressive, but honestly, the implementation difficulty is outrageous, and security risks haven't been addressed. Do your own research, everyone. The Cancun dividend has been exhausted. Next, it depends on whether there are real capabilities to eliminate fragmentation. Currently, it's still in the pie-in-the-sky stage. The fee battle has been won, but interoperability hasn't started yet. It feels like the next round will be the real test. Zero-knowledge proofs sound explosive, but to really run stably? Brother, don't think too much. Wait for the verification results.

The fee reduction feels great, but L2 fragmentation is really a headache. Interoperability sounds nice, but what about reliability? Still a question mark. EIP-7503, whether reliable or not, we'll have to wait and see. This upgrade is like patching a hole only to dig another one. It's still early to say if it will be truly useful; don't be fooled by the hype.
