I’ve been digging back into the IBC/message-passing setup lately, and the more I look at it, the more I feel like cross-chain, in plain terms, is really about “who you trust.” When moving from chain A to chain B, it’s not only about whether the bridge contract is written correctly—you also have to trust: whether the verification/relayer folks will slack off, whether there are any pitfalls in the light client/consensus proofs, whether the target chain’s execution of that message will get reorganized or get stuck, and even whether the frontend and RPC you use might feed you fake data… In any case, the more components there are, the naturally larger the trust surface becomes.

So, when I do moving-stones/arbitrage myself, I’ve increasingly become “habitually” to first break down the trust chain: on this path, who could act maliciously on their own, how high is the cost of doing harm, and whether I can stop immediately if something goes wrong. Don’t always assume that rare talent can dodge black swans; more often, what helps people live long-term is habit: each time, take one more look at the proofs, and be less greedy for that small cross-chain subsidy.

One more thing—recently there’s been this kind of social mining/fan token scheme that claims “attention is mining,” and to me it just sounds exactly like the marketing of certain bridges… It sounds very profound, but when it actually comes down to it, it still returns to how trust and incentives are designed. Without that, no matter how high the hype is, it’s just noise.
