Just showerthoughts as a non-expert on data availability for validiums: what if we could take StarkWare's adamantium concept and structure it into a permissionless DAC? Users can choose (& vote for) their preferred DA provider(s) or do it themselves.

Now, the voting may make it sound like DPoS, but you don't actually need to come to consensus. As long as an n number of DA providers (by vote) sign off, the validium can transition. If the validium freezes, you only need to trust your preferred DA provider or yourself.

Essentially, you have a baseline DAC that sign off state transitions - except instead of being permissioned it's voted in by governance. On top of that, you add a 1-of-N trust layer with adamantium. I could be wrong - but we're now approaching OR type trust assumptions.

Just to be clear: this is not about replacing the highly secure Ethereum DA, i.e. rollups. It's more about looking for ways improving the status quo with permissioned DACs or DA with a relatively centralized consensus mechanism.

Of course, you can also have this setup on top of a baseline consensus mechanism instead of a baseline committee. See here:
