Recently, when I check on-chain data, it keeps “freezing for a moment.” At first, I even thought it was my internet connection… Later, it occurred to me that it’s probably not the chain itself that’s slow, but the whole bunch of middlemen who are gasping for breath. For example, Subgraph/indexers have to first “organize the blocks into the format you want to query.” If you flip through too many pages at once, they have to compute it on the spot. RPC is the same: when too many people are using public nodes, they throttle the traffic, and what looks like your transactions have stopped is actually just queuing.

It’s a bit like going to the convenience store after work to buy coffee: the shelves are right there, but there’s only one cashier, and a long line forms behind you. So you can only stand around waiting, wondering whether the coffee has already sold out. Lately, people have been discussing rate-cut expectations, the Dollar Index, and how risk assets rise and fall together. Everyone rushes in to refresh and scrape data, and public RPC is even more likely to get overwhelmed… In any case, I’m not panicking when my dashboard “stalls” now. I’ll switch nodes, reduce the query frequency, or just wait two minutes before checking again—so I don’t let my own anxiety end up driving the whole situation.
