Recently digging into IBC / cross-chain message passing, the more I look at it, the more I feel that "who to trust in a cross-chain transaction" is more important than "how to cross." To put it simply, you're not just moving tokens over, you're sending a proof of state + message, and the target chain needs to trust: whether the other chain itself has finality, whether the light client / validator set updates are reliable, whether the relayer (the transporter) will block you / deliver incorrectly, and whether the channel / contract implementation has pitfalls. Bridges are even more complex; many actually rely on an additional layer of multi-signature / oracle / custodians, and it's normal for issues to occur...

Thinking about the kind of inflation + studio + coin price spiral in blockchain games, if cross-chain bridges add a "liquidity expansion out of thin air," it really makes me a bit anxious. Anyway, whenever I see "cross-chain asset issuance," I first ask: who does this bridge trust? Please clarify before proceeding.
