AirGap Vault Distribution

AirGap Vault Distribution can be started from a CDROM or an USB stick on a computer and being used to sign air gapped transactions. The AirGap Vault Distribution is the equivalent of the mobile version of AirGap Vault, use the mobile app AirGap Wallet to broadcast transactions.

Setup AirGap Vault Distribution

Copy AirGap Vault Distribution to a CDROM or USB stick

CDROM:
use your favorite program to burn the ISO to CDROM. Nothing special. CDROMs are naturally read-only and tamper resistant.

USB:
If you don't burn AirGap to a CDROM, writing AirGap Vault to a USB stick with a hardware read-write toggle (e.g., Kanguru FlashBlu) is the next best thing.

On USB sticks without write protection, you can remove the AirGap Vault USB after booting as an additional security measure. AirGap loads into RAM so after booting you no longer need the USB.

  1. Insert USB stick and detect the device path::
$ dmesg|grep Attached | tail --lines=1
[583494.891574] sd 19:0:0:0: [sdf] Attached SCSI removable disk
  1. Write ISO to USB::
$ sudo dd if=path/to/airgap.iso of=/dev/sdf
$ lsblk | grep sdf
sdf                                8:80   1   7.4G  1 disk  
└─sdf1                             8:81   1   444M  1 part
