-The `dss` message sends the user's signed inputs for a group transaction in a
-mixing session.
+The `dss` message replies to a `dsf` message sent by the masternode managing the
+mixing session.  The `dsf` message provides the unsigned transaction inputs for
+all members of the mixing pool. Each node verifies that the final transaction
+matches what is expected. They then sign any transaction inputs belonging to
+them and then relay them to the masternode via this `dss` message.
+
+Once the masternode receives and validates all `dss` messages, it issues a
+`dsc` message. If a node does not respond to a `dsf` message with signed
+transaction inputs, it may forfeit the collateral it provided. This is to
+minimize malicious behavior.
