Modular blockchain... in simple terms, it means splitting the tasks that were previously handled by a single chain into several parts, each running independently. It sounds very engineering-oriented, but for someone like me who only cares about whether NFTs can be minted normally, the change is actually quite subtle.

In the past, when gas spiked, the entire chain would get congested. Now, the execution layer can be swapped out; if it's cheaper, you switch over. After all, my wallet only recognizes whether the final transaction is on-chain or not. The experience is that "it's not as easy to get stuck anymore," but it hasn't reached a qualitative change. After all, the frontend is still the same frontend; the abstraction isn't good enough.

Recently, AI agents are everywhere, automatically bidding the floor price for me, automatically cross-chaining — it sounds futuristic. But to be honest, handing my private key to an agent I don't understand feels about the same as handing it to a contract I don't understand in terms of fear level. Maybe I'm still old-school; I'd rather manually create a few redundancies — one copy in a multi-sig wallet, one on hardware, and one set of seed phrases in my memory. It's not that I don't trust the technology; it's that I don't trust myself not to make mistakes.

That's it for now. No matter how far modularization advances, if you don't manage your keys well, you'll end up with zero anyway.
