Wasabi Setup on Tails


This essay is extracted from this step by step guide, which also includes tutorials on how to install Tails, create a persistent storage and use Bitcoin Core alongside with it.

CREATE ADMIN PASSWORD

You need sudo privileges to install Wasabi, at “Tails Greeter” create your admin password in “additional settings” and launch Tails.

gpg -v Wasabi-X.X.X.deb (For more details check this guide)

You can now save your Wasabi-X.X.X.deb into the persistent storage, which should look like this:

/Persistent
|__ /bitcoin-0.18.1    # Bitcoin Core launcher folder
|__ /Bitcoin           # Bitcoin Core data folder
|__ /Wasabi-X.X.X.deb  # Wasabi installer

WASABI DATA FOLDER

As of version 1.1.9 Wasabi doesn’t offer easy ways, especially without command line, to change install directory. There is though a quick workaround.

Wasabi saves session files in /Home/.walletwasabi/client, you need to mark the “show hidden files” setting to see it.

Create a directory in your persistent with the same hierarchical structure, like this:

/Persistent
|__ /bitcoin-0.18.1    # Bitcoin Core launcher folder
|__ /Bitcoin           # Bitcoin Core data folder
|__ /Wasabi-X.X.X.deb  # Wasabi installer
|__ /.walletwasabi
    |__ /client        # Here we save our wallet files, filters and blocks

After every session, when you’re done, navigate into /Home/.walletwasabi/client and copy the desired folders into your persistent directory.

Generally, you’d like to save the Wallets and Blocks folders.

The former contains your wallet information (e.g. keys, labels), while the latter includes the blocks needed to establish your balance.

Could be also nice to save the BitcoinStore folder, which contains the BIP 158 block filters, so that you don’t have to download them again.

INSTALL WASABI

Drop the Wasabi-X.X.X.deb file from /Home/Persistent into desktop.

Open the terminal and run:

cd Desktop
sudo dpkg -i Wasabi-X.X.X.deb

Type the password you created at “Tails Greeter”.

(Info about dpkg)

Wasabi will show as a normal application in your activities overview menu, ready to start.

LOAD FROM YOUR DATA DIRECTORY

After the first time you save a Wasabi session, your persistent storage will look like:

/Persistent
|__ /bitcoin-0.18.1        # Bitcoin Core launcher folder
|__ /Bitcoin               # Bitcoin Core data folder
|__ /Wasabi-X.X.X.deb      # Wasabi installer
|__ /.walletwasabi
    |__ /client            # Here we save our wallet files, blocks and filters
        |__ /Wallets
        |__ /Blocks
        |__ /BitcoinStore

To load your saved session, drop the .walletwasabi folder into /Home before starting Wasabi.

You can save multiple copies of .walletwasabi in your persistent, each with different data:

/Persistent
|__ /bitcoin-0.18.1                # Bitcoin Core launcher folder
|__ /Bitcoin                       # Bitcoin Core data folder
|__ /Wasabi                        # General Wasabi folder
    |__ /Wasabi-X.X.X.deb          # Wasabi installer
    |__ /BitcoinStore              # Filters (No need to keep multiple copies of them)
    |__ /CoinJoin wallet
    |   |__ /.walletwasabi
    |       |__ /client            # Here we save our wallet files and blocks
    |           |__ /Wallets
    |           |__ /Blocks
    |__ /watch-only coldstorage A
    |   |__ /.walletwasabi
    |       |__ /client
    |           |__ /Wallets
    |           |__ /Blocks
    |__ /watch-only coldstorage B
        |__ /.walletwasabi
            |__ /client
                |__ /Wallets
                |__ /Blocks

This is only a minor example, tune it to your own needs.

Remember to do backups!
