     There are two possible statuses for a timestamp:
     - `Pending`: The timestamp has been submitted to the calendar server but has not yet been confirmed in the Bitcoin blockchain.
-    - `Confirmed`: The timestamp has been confirmed in the Bitcoin or Litecoin blockchain.
+    - `Confirmed`: The timestamp has been confirmed in the Bitcoin blockchain.
 
     ### Upgrading Timestamps
     To upgrade a timestamp from 'pending' to 'confirmed', you can use the `ots upgrade` command from the opentimestamps-client package
