My assumption is that
FAILURE_SAFETY refers to how many nodes in your quorum slice you allow to fail while
QUORUM_THRESHOLD refers to the percentage of nodes in an quorum that's necessary to come to a consensus?
So I if configure
3 validator nodes with
QUORUM_THRESHOLD=66, that means if more than one of the
3 nodes fail I will fail while
QUORUM_THRESHOLD may contain other nodes that are not part of my configuration?
