These days, the task platforms during airdrop season have been messing with me like clocking in for work... The anti-witchcraft measures are getting more and more complicated, and as a result, everyone cares more about "how to pass the rules." Cross-chain itself is already full of pitfalls.

My understanding of a cross-chain (whether called IBC or bridge) is basically: on chain A, lock or burn tokens, and you have to trust that chain B can "correctly know that this really happened." So who do you trust? One layer is the consensus and finality of the chain itself (no rollbacks); another layer is the verification mechanism for message passing (light client/proof—who is actually verifying); a third layer is the relay/listener (they can choose not to cheat but can also slack off and block you); and then there are "human-controlled switches" like bridge contracts/upgrades, many accidents are actually caused by these. Anyway, when I see "instant cross-chain transfer," I first ask: where exactly are you placing your trust? If I’m wrong, feel free to correct me—I’m also digging through the materials.
