Recently, I've seen a bunch of people complaining that validators are eating up too much, and that MEV ordering is unfair. Thinking about it, it's normal: once you cross chains, the trust surface area becomes as large as opening a new line of communication. For something like IBC, don't just look at "messages being sent out"; you're actually trusting the consensus/validators of both chains, the light client verification (avoid bugs), relayers (don't go offline or mess up), plus how the application layer handles timeouts/replays. Bridges are even more complex: multi-signatures, oracles, guardians, custodial contracts... with more components, the probability of issues increases. To put it simply, cross-chain isn't just "transferring assets"; it's "packing up the reputation of a bunch of people and code." I now prefer to go slower and cross less whenever possible.
