Recently, everyone has been arguing again about L2 compared to TPS, costs, and subsidies, which is quite lively... But if you really want to transfer assets/messages across, honestly, you haven't lost any trust in what you believe. One cross-chain (whether called IBC or other messaging protocols) requires trusting: that the source chain won't rollback itself, that the light client/verification logic won't be broken, that the relayer/relay won't act maliciously or get stuck, that the target chain won't have bugs in executing this proof, plus the application layer contracts that "mint/unlock upon receiving messages" must have no vulnerabilities. The faster the bridge, the more it often exchanges security for operational/economic guarantees; you're just shifting trust from the chain to people and mechanisms. Anyway, before I cross chains now, I always think carefully: am I trusting consensus, or a committee/multisig? I want to understand this clearly before acting. Forget it, I won't get into a flame war now.
