Lately, checking on-chain data has been a bit frustrating: you think you're monitoring "real-time," but most of the time you're actually looking at the "cached version" provided by RPCs or indexers. When node synchronization is slower, RPC load is higher, or the index service rebuilds, the smart money's path can appear minutes or even longer after you, causing delays... To put it simply, it's not that the chain is slowing down, but that the window you're looking through has latency.

These days, everyone is talking about rate cut expectations and the US dollar index. Risk assets sometimes rise together, sometimes fall together. I'm actually more worried about the "chasing" impulse driven by emotions, because when data is delayed, it's easiest to misjudge it as "sudden volume increase / sudden reflow." Now I cross-check two or three data sources, at least compare the same large transfer across different RPCs, to feel more at ease.

For now, I'll do that. I'm going to measure the latency of two commonly used RPCs and also make a table of the indexer's update times.
