Just now, I stared at an address for a long time, feeling pretty pleased: blockchain transparency.

But then I switched to a different RPC and refreshed, and the timestamps and event order became "more reasonable"...
To put it simply, what you often see as "on-chain" is: nodes first sync, RPC then relays, indexers digest, and finally tools tag for you.
If any step in the middle stalls, you'll think the whales are playing you, but actually you're just seeing delayed playback.

Recently, some people have been criticizing certain on-chain data tools/tagging systems for lagging or even being misleading.
Now I believe: tags are made by humans, humans can be lazy, indexes are run by systems, systems queue up.
Anyway, I now check data from two or more sources, confirm the same block height before trading, or else that "OCD's tiny fee savings" will end up costing me through information gaps.
The market never rewards overconfidence, especially confidence based on delays.
