The tier system can really help with communications between the foundation.
The 3 problems are:
Decentralization
We have been told that eventually the foundation might step away from the project. So we need to prepare for that. The “Executive arm” is a step towards that goal but doesn’t fully commit to the idea. While the Tier system will align everyone on the same path and as the power of decentralization becomes more robust, the foundation can slowly hand over their roles to the Tier 1s.
Communication
The foundation and Tier 1s needs to be on the same page. Same databases. etc. Not too hard to do…
Giving all the executive decisions to an “executive arm”, just moves the power from one group to another… Without a democratic system in place eventually one will need to be created and we will need to commit to full decentralization anyway.
