 ## Message Persistence 
 
 All messages will saved in a SQLite DB and restored upon relaunch of the app.  You may delete `client.db` if you wish to erase all stored messages and node data.  If multiple nodes are used, each will independently store data in the database, but the data will not be shared or viewable between nodes.
