Lately I’ve been working on IBC and all sorts of messaging/bridge-related things, and the more I look into it, the more it feels like cross-chain, at its core, is just: “Who exactly am I trusting?”

A transfer across involves the chain itself, light clients/validators, forwarding relayers, bridge contracts, oracles (some even throw in a multisig/admin setup)… and every additional layer means another row in my spreadsheet: “might end up tweaking parameters to the point of death.”
I’m kind of no longer trying to explain everything anymore—I’ve decided to accept the randomness: if you can understand part of it, start by testing with the smallest amount; don’t just take your assets and toss them across as if they were faith from the very beginning.
Also, lately there’s been a pretty heated argument over privacy coins/mixers and compliance boundaries, and I actually care more about: will this bridge one day suddenly add a blacklist, or will the relayers collectively just go dead… If the parameters aren’t tuned properly, then consider it paying tuition.
