It feels like many people say "I saw it on the chain," but that's not necessarily real-time... It's more like you're seeing the chain through someone else's eyes. Will nodes drop blocks, is there rate limiting on RPC, how do indexers catch events—these factors can make what you see lag behind, or even miss a segment, and then you start doubting whether you saw it wrong.

Recently, I traced a few transaction paths, and the same transaction shows different times on different browsers/different RPCs; sometimes you see the swap first and then the transfer, the order can be all over the place, which is pretty outrageous but also understandable. To put it simply, the on-chain data is objective, but the access points are not.

By the way, I thought of the recent NFT royalty debate, where some people use "on-chain data proves creator income is like this or that" to argue back and forth. Actually, if the data source changes, the conclusion can be distorted... Anyway, when I look at the chain now, I first ask: whose index is this, how much is the delay, and is anything missed? Be cautious, avoid being led by screenshots and hype.
