Running Bisq on Tails

Overview

Unlike most operating systems, Tails runs entirely in memory. When Tails shuts down, memory contents are deleted, restoring the OS to its original state. Only files saved to the Persistent Storage survive a reboot.

Therefore, Bisq must be reinstalled (and configured) after every boot. More importantly, Bisq's default data directory must be relocated to the Persistent Storage so that your wallet, keys, etc. are not lost every time Tails shuts down.

This is easy to automate with an installation script.

Preparations

Configure Tails

On the Tails Welcome Screen:

Once Persistent Storage has been created, a settings window will open automatically. You can also open it from the desktop menu: Applications > Tails > Persistent Storage.

  • Enable the Persistent Folder in the above settings.

Configure the Persistent Folder

  • Create a directory to store the Bisq installer (and installation script):
mkdir /home/amnesia/Persistent/bisq/
  • Create a persistent data directory for your Bisq user data:
mkdir /home/amnesia/Persistent/bisq/Bisq/

Import user data from backup

Warn
WARNING: Ensure that the persistent data directory is EMPTY before importing. Do NOT mix user data from different sessions.

If you wish to import user data from a previous Bisq installation or backup, copy it into the persistent data directory:

  • cp -ra /[backupdirectory]/bisq_backup_version001/. /home/amnesia/Persistent/bisq/Bisq/

N.B. The correct path to your btc_mainnet directory should now be:

/home/amnesia/Persistent/bisq/Bisq/btc_mainnet

Download Bisq

mv /path/to/[yourdownload.deb] /home/amnesia/Persistent/bisq/

Create installation script

NOTE: The script below will install Bisq, configure Tor, and redirect user data to the persistent data directory (by creating a 'symbolic link'). Every step in the script is explained via 'echo' commands.

  • Create a new script file:
touch /home/amnesia/Persistent/bisq/install-bisq.sh
  • Make the file executable:
chmod +x /home/amnesia/Persistent/bisq/install-bisq.sh
#!/bin/bash
BisqInstaller=/home/amnesia/Persistent/bisq/[yourdownload.deb]
DataDirectory=/home/amnesia/Persistent/bisq/Bisq

Run Bisq

NOTE: Your user data is safely stored in the persistent data directory. However, the Bisq application is 'uninstalled' every time Tails shuts down.

To install Bisq:

  • Connect to the Tor network, via the desktop menu:
Applications > Internet > Tor Connection
sudo sh /home/amnesia/Persistent/bisq/install-bisq.sh

Once Bisq has been installed, you can either start it from the desktop menu:

  • Applications > Internet > Bisq

Or via terminal:

  • /opt/bisq/bin/Bisq --torControlPort 951 --torControlCookieFile=/var/run/tor/control.authcookie --torControlUseSafeCookieAuth

Maintenance

Backup user data

While Bisq is running

You can backup while Bisq is running, as normal.

While Bisq is closed

You can also backup while Bisq is closed, by copying your user data to a backup location. However:

Warn
REMEMBER: Your user data is stored in the persistent data directory, and NOT Bisq's default data directory.

WARNING: Only backup data into an EMPTY directory. Do NOT mix user data from different sessions.

To backup, first create a new (empty) directory for the backup, then copy the persistent data directory. For example:

  • mkdir /[backupdirectory]/bisq_backup_version001
  • cp -ra /home/amnesia/Persistent/bisq/Bisq/. /[backupdirectory]/bisq_backup_version001

Upgrade Bisq to the latest version

Warn
WARNING: Do not downgrade Bisq. Installing an older version could cause irreversible damage to Bisq data.

NOTE: Before upgrading, it is recommended to backup your user data.

To upgrade Bisq:
