   Yes.
   
   > (and whether the S3 Gateway ever supports intended anonymous access).
   
   When security is enabled, no, anonymous access will be rejected. (At least 
there is no plan for that right now, see 
https://issues.apache.org/jira/browse/HDDS-7961)
   
   > * **Q-ratis** — the Ratis honest-majority safety bound you stand behind, 
and whether there's an **independent block/container integrity check** so a 
single Byzantine datanode can't serve corrupted data undetected.
   
   Ratis gives standard Raft safety under an honest majority, e.g. 2 of 3 
replicas for RATIS-3. It is not Byzantine fault tolerant.
   
   Ozone has checksum verification for normal reads and replica/container 
checks, so ordinary single-replica corruption is detected. But I would not 
claim a full guarantee against a Byzantine datanode that can forge both data 
and metadata on the path it serves
