Today, when I was checking on-chain data again, I ran into that “stuck for a moment” feeling—transactions were clearly submitted, but the page just wouldn’t update… I only gradually understood it later: some sites don’t query the chain directly; instead, they go through an indexer/Subgraph first, organize the on-chain data, and then show it to you. If it falls behind, it’s like you’re watching a delayed live broadcast. On top of that, RPC rate limiting is even more annoying—especially during airdrop season, when everyone is running tasks, anti-sybil (anti-witch) teams have a bunch of scripts hammering the interfaces, and the point system has turned the “farm points for rewards” crowd into something like a clock-in workforce. When public nodes can’t take it, they start giving you 429/timeout responses, and the frontend ends up showing “Loading…”. Now when I see it lag, I’m not that worried anymore—I switch nodes, wait a few minutes, or just compare against a block explorer. Anyway, I’m not pretending to be an expert; I’ll just observe for now. That’s it for now.
