Lately, people have been talking a lot about "modular blockchains." At first, I thought it was quite distant from me as a regular end-user—just clicking a wallet, signing a transaction, the interface all looks pretty similar. But then I realized, what it truly changes might not be "what I see," but rather "that I no longer have to pick a side for each chain"—applications are separating execution, data, and consensus, making migration less painful, and if something goes wrong, it doesn't cause a total collapse.

But on the other hand, it’s also quite subtle: the more layers there are, the easier it is to stack stories. Recently, the staking/shared security model has been criticized as a "nested doll" setup. I can understand why—profits look tempting, but risks are hidden in unseen interfaces. To put it simply, the biggest change for users might be: more choices, but also harder to tell which layer’s consensus they are actually trusting. Let’s leave it at that for now and observe gradually.
