The original Cwtch paper defined a set of properties that Cwtch Servers were

never learn the identity of participants within a group.

### Detectable Faults
* If a Cwtch server fails to relay a specific message to a subset of group
members then there will be a detectable gap in the message tree of certain
peers that can be discovered through peer-to-peer gossip.

* A Cwtch server cannot modify any message without the key material known to
the group (any attempt to do so for a subset of group memebers will result in
identical behavior to failing to relay a message).
* While a server *can* duplicate messages, these will have no impact on the
group message tree (because of encryption, nonces and message identities
) - the source of the duplication is not knowable to a peer.
