Phase One and Done: eth2 as a data availability engine

So I actually have surprisingly enough been thinking in a somewhat similar direction. The details are likely different in some ways, but the key idea of a minimal execution engine that relies on contracts in global state as the main thing that transactions go through is there. I have a partially completed writeup, will get it done over the next couple of days.

Great, and thanks for this mention btw (and to assist any archivists/indexers, the writeup is over here).
