Recently studying IBC, the more I look at it, the more I feel that "cross-chain" is essentially asking: who do I trust?

I used to think a bridge was just a lock, lock it and it's done... but I found out that in a cross-chain transaction, you need to trust a series of components: the source chain itself must not rollback, the light client/verification logic must be correct, the relayer (the one who moves messages) must not go offline or mess up, and the target chain must honestly accept according to the rules;
if you use multi-signature or custodial bridges, there's also an additional layer of "people" and operational risk.

Now, with so many people incentivized on testnets and earning points, and everyone in the group guessing whether the mainnet will issue tokens, I also feel the itch, but thinking about how reckless it is to cross chains just for points...
As a newbie who often makes mistakes even in drawing lines, I’d rather clarify the trust chain first before taking action.
Slow down, then slow down.
