Interoperability via MACH

If a RaaS provider had many instantiated rollups, then to have interoperability across the rollups, one would normally build an enshrined bridge on the DA layer, one per rollup. An alternative would be to have one bridge between every two rollups that use the same DA layer.

With AltLayer, we adopt a third design that leverages MACH to serve as a bridging hub to coordinate across all rollups.
