Lately, I've been noticing that on-chain data always seems to "lag," sometimes balances don't match, and transaction records only appear a few minutes late. Thinking about it later, it makes sense: the indexer/Subgraph has to scan through blocks before presenting the data to you, RPCs might also be rate-limited, and when free nodes are busy, it's like waiting in line for a number. The frontend caches some data, so the experience feels like it suddenly speeds up or slows down.

So I no longer trust a single source; when I see anomalies, I compare two or three different sources, or simply wait ten minutes before checking again—don't make a mistake just because of a momentary data fluctuation. This is even more obvious in blockchain games, where inflation plus studio-driven hype causes a surge, then when the coin price retraces, data delays again, and the sentiment spirals. Anyway, I prefer to take it slow for now.
