These days, someone is again complaining that miners/validators make a lot of money and that MEV makes ordering unfair.

As I watch, I think: cross-chain bridges are more like a wooden bridge at night; don’t just look at whether the lights on the other side are bright, you need to see who is tightening the screws at the bottom of the bridge.
To put it simply, multi-signature is not just about the words "more secure"; who signs, and whether the same line gets compromised, are the key points.
Oracles are the same—feeding incorrect data once, and even if subsequent actions follow the rules, it can still lead to a crash.
Actually, I now wait for multiple confirmations when crossing bridges—better to be a little slower, at least give myself some time to back out.
Anyway, those few minutes of urgency often end up being paid as tuition fees.
