Last night, I was checking on-chain data and started to doubt myself: for the same transaction, on my side it shows "Completed," but on my friend's side it's still "Unconfirmed"... Thinking about it later, it's not so mysterious; nodes, RPC, and indexes are like food delivery: the rider (node) definitely delivered, but maybe you're looking at a platform's delivery info (RPC) that hasn't refreshed yet, or third-party statistics (index) are queued for update, so what you see on the "chain" could be delayed by a few minutes.

Recently, there have been a bunch of AI Agents and automated trading interacting wildly with the chain, honestly, I'm more worried about whether they are reading the latest state or not... Some people hype up the narrative to the sky, while others quietly focus on security and data source consistency. Anyway, I’m increasingly hesitant to rely on just one entry point for conclusions. For now, I’ll just add a "delay buff" to my pixelated little theater.
