Lately, I’ve become increasingly hesitant to casually say "on-chain is real-time."

The transfer in your wallet, the liquidation in DeFi—sometimes it’s not that they didn’t happen, but that the nodes/RPC you’re connected to are queuing, rate-limiting, or even returning outdated data; plus, with indexers scanning blocks, building databases, and generating charts, any delay in these steps can cause the "on-chain status" you see to be minutes or even longer behind.
To put it simply, on-chain is on-chain; what you see on your phone is "on-chain translated for you by others."

Recently, everyone has been comparing RWA, US bond yields, and on-chain yield products.
I get tempted too, but I care more about the data sources: whether it’s cash flow or subsidies—setting that aside—if even the basic data is delayed, risk alerts could also be lagging… which is pretty dangerous.

What I fear missing the most isn’t actually opportunities, but that risks have already occurred while I still think everything is normal.
