Fault Tolerance, Concurrency, Transparency, QoS of Solid

Hello Guys,

I am new to Solid. I am analyzing it from a distributed system perspective.
Specifically, I am looking at:

  1. Fault tolerance (Crash, Byzantine, Omission, Timing) of Solid
  2. Concurrency
  3. Transparency
  4. QoS

I failed to find documentation concerning these things. Any leads or explanations would be greatly appreciated. Thanks!
