Lately, everyone has been arguing again about cross-chain bridges being hacked. As this "On-Chain Gossip Auntie," I can only keep nagging: a cross-chain transfer, to put it simply, isn't just about "moving tokens over." You're actually betting that none of the components fail— the chain sending the message must truly produce a block, the packager must not cause trouble; the relay/validator in the middle must honestly pass the message; the target chain's receiving contract must have no backdoors; plus, there's the signature threshold, who has upgrade permissions... if any link is compromised, it can turn into "minting tokens out of thin air." After that oracle incident with the abnormal quote, everyone learned to "wait for confirmation," which is pretty realistic—taking a bit longer at least exposes problems when they happen. Oh, my partner also complained about me: you can stare at a transfer diagram all night, but when I click the cross-chain button, I have to keep talking about the trust model for half a day... Isn't that annoying? Anyway, now before I do a cross-chain transfer, I check permissions and validator decentralization. If I'm unsure, I take fewer steps.
