In the past two days, the group has been discussing the matter of a certain mainstream public chain's upgrade/maintenance, and everyone is guessing whether the ecosystem will "move out collectively." I'm actually more concerned about: when it comes to cross-chain, who do you really trust? For messages like IBC, the trust aspect feels relatively clear—it's based on the consensus of both chains plus light client verification, and problems are easier to pinpoint; but once you go through a "bridge," it easily becomes: do you trust multi-signature/relay services, trust the data fed by oracles, trust that the smart contract isn't written to explode, and also trust that the chain itself won't rollback... Anyway, with more components, the fee structure becomes like a patchwork, and it's not surprising if some parts are expensive or slow. I personally now do small, incremental cross-chain transfers; I prefer to go through multiple steps rather than bundle all trust into one shot.
