These days, I've been looking into IBC stuff, and the more I read, the more I feel that cross-chain is basically about "who do I really trust."

Once a transaction is completed, the chain's consensus mechanism, message passing system, and the execution modules—any of these could malfunction and make you think you've arrived somewhere when you actually haven't…
No matter how much the bridge is wrapped up, in the end, it's still a trust boundary issue.

I can also understand why recently staking/sharing security has been criticized as "copy-paste," with layered yields sounding very attractive, but trust is layered too.
Risks don't just disappear; they’re just hidden somewhere else.
Anyway, now I pay more attention to: who proves this message, and who will cover the losses if something goes wrong, rather than just looking at where I can get more.
