Lately, I've been looking at the IBC / cross-chain setup again, and the more I look, the more I feel that a single "cross over" is actually just pressing confirm on a series of things: the source chain must not rollback itself, the proof sent out must be reliable; the relayer/message passing layer must not be lazy or malicious; the target chain's light client/verification logic must be correct; plus, the multi-signature/oracle/escrow of the bridge (some even have an extra layer), and trust is laid bare... To put it simply, it's not as simple as clicking a button. I'm also reviewing the comparison between RWA and US Treasury yields versus on-chain yield products, and the more I compare, the more I want to ask: is this yield really from "the asset itself" or from "bridge + contract + operation"? My own definition of "long-term" is probably about a quarter; I don't expect results every day. First, I want to understand the trust chain clearly, and then I can wait patiently.
