Recently, people keep asking me: why does on-chain data sometimes seem to "lag," even though the blocks have been produced, and the wallet/dashboard hasn't updated yet. Actually, many times it's not the chain itself that's broken, but the middle layer that's struggling: indexers need to translate raw on-chain logs into searchable results, and subgraphs have to run mappings and write to databases; plus, with RPC rate limiting, when there's a hot topic (like memes or celebrities shouting, and everyone rushes in), requests can explode, leading to queues, dropped packets, and old data being returned—making it look like a "delayed reality."

Forget it, to put it simply: you think you're watching a live broadcast, but you're actually watching a replay edited by someone else. When the editor is overwhelmed, they just blur a frame for you first.
Veteran players advise newcomers not to take the last baton, and I think it also includes not staring at a "not refreshed" number during the loudest moments and getting scared. It's normal to be a bit slow; if you really want to confirm, switch to several sources and wait a few minutes before drawing conclusions.
