Recently, I've seen everyone talking again about whether a main public chain upgrade/maintenance will cause the ecosystem to move together. My first reaction isn't "which chain to go to," but rather "who do I trust to cross over this step." For a cross-chain message/asset, superficially it seems simple, but at least you have to trust: the source chain itself won't rollback or reorganize too ridiculously; the relay/light client or validator set won't mess around; the message proof won't be forged; the contract on the destination chain executing that message isn't missing anything; and the frontend routing won't secretly change paths. The benefit of the IBC system is that it binds trust as much as possible to consensus and proof, but the real implementation still depends on the details and the security boundaries of the other chain. Anyway, I no longer believe that "just big-name bridges are safe," so before each cross-chain transfer, I wait for several confirmations, preferring to be slow and pay less tuition.
