Recently, people keep asking me "Why does on-chain data keep lagging?" Basically, what you're seeing isn't the chain itself lagging, but your data service layer is struggling. Many pages use indexers/subgraphs, first scanning the chain, then storing data, then querying; when there's a reorganization, rollback, or index rebuilding, it suddenly slows down. Switching to direct RPC isn't necessarily stable either; public RPCs have rate limits (like 429 errors) or nodes lag behind by a few blocks, making the frontend freeze and spin.

What's more annoying is that in the group, some are discussing stablecoin regulation/reserve audits, while others shout "it's losing its peg again." When everyone's emotional, they focus even more on those few data refreshes... I stared at it last night, my eyes hurt so badly. Anyway, I've gotten used to this: for the same transaction, compare the block height using two different RPCs + block explorers; if they don't match, first assume cache/rate limit issues, don't immediately suspect the chain is about to collapse. That's it for now.
