Today I encountered that moment again where "on-chain data gets stuck," even though the block has already been produced, the page still seems unresponsive... Frankly, many times it's not the chain slow; it's the data services in the middle catching their breath. Indexers need to split the new block, store it, then feed it to the subgraph; if you refresh frequently, it queues up, and when reorganizations happen, it has to roll back and recalculate. On the other end, RPCs also limit flow, and free/shared nodes get a 429 when busy, making you feel like you're offline, but actually they're throttling the frequency.

Recently, I’ve also enjoyed watching the L2s argue about TPS, fees, and subsidies, but in actual use, I care more about whether "the data can be stable": don’t make me spin in circles just to check a balance when doing a task... Anyway, my current habit is to keep the txhash for key steps so I can verify it myself; if the page gets stuck, I switch RPCs first, and if that doesn’t work, I wait ten minutes. First, note down the few rate-limiting points I hit today into the airdrop map.
