Recently, on-chain data keeps "hanging," but actually, it's often not the chain itself being slow, it's the layer you're viewing struggling... The frontend sends a bunch of requests to RPC first, and when rate-limited, they queue/retry; further down, if it goes through Subgraph/indexers, it has to first process new blocks, parse, store in the database, then return the query results. Even if a node goes offline or rolls back in the middle, the page feels like it's suddenly disconnected.

To put it simply: what happens on the chain ≠ what you can read immediately and stably. Modularization, DA layer narratives are popular among developers, but ordinary users just feel "loading again," and the user experience actually depends more on the stability of these underlying services. Anyway, I now check data from several sources at once to avoid being misled by the "truth of the hang." That's all for now, I’m off to work.
