3. A consortium of permissioned parties. I'm assuming at least the 3 major banks and some if not all of the 70 companies.
This is similar to Diem (aka Facebook Libra). PoA (Proof-of-Authority) as opposed to PoW or PoS.
The point is that the parties keep each other in check, and collectively have some level of fault tolerance. At the scale of a national economy, it's desirable to not have a single point of failure on an institutional level.
If you think "Signed Git+Raft/Paxos", that's pretty close.
I'm curious if they'll allow some level of unpermissioned access to the chain and/or for individuals to manage their own keys. The pessimist in my thinks no, but one can dream.
