Lately I've been looking at IBC, various message passing, and bridges. The more I look, the more I feel that crossing a chain is actually just shaking hands with a series of "trust points": the source chain doesn't roll back, the light client/validators don't mess around, relays don't go offline, and the target chain doesn't do weird things during execution; if you use a bridge, you need an additional layer of multi-signature/oracles/escrow contracts—any extra layer just gives more reasons for something to go wrong. Modularization and the development of the DA layer are making developers really excited, but on the user side, it's just one sentence: can I settle when I cross over, and not get stuck for half a day. Honestly, for small fund arbitrage, I focus on settlement time and failure costs. The fewer components I trust, the better... What I still believe is: no matter how much chains tell stories, ultimately, settlement speaks.
