---------------------------------
2016-07-05 07:38:17 -04:00
A "split" bitcoin wallet is a strategy of protecting your bitcoin by having your wallet split into an offline "[cold storage](https://en.bitcoin.it/wiki/Cold_storage)" wallet and an online "watching only" wallet.
A "Watching" Wallet and a "Cold" Wallet
---------------------------------------
1. Create a fedora-25-electrum template using the Qubes VM Manager or running
`qvm-clone fedora-25 fedora-25-electrum` in dom0.
2. Start the new template:
`qvm-start fedora-25-electrum`
`qvm-run fedora-25-electrum xterm`

3. Install `electrum` to fedora-25-electrum template VM. From fedora-25-electrum terminal enter:
`sudo dnf update`.
`sudo dnf install electrum`.

5. Create an `offline-bitcoin` qube based on `fedora-25-electrum` using the Qubes VM Manager or running `qvm-create -t fedora-25-electrum -l black offline-bitcoin` and `qvm-prefs -s offline-bitcoin netvm none` in dom0.

7. Create a `watching-bitcoin` qubes based on `fedora-25-electrum` connecting to the internet how ever you prefer using the Qubes VM Manager or running for example `qvm-create -t fedora-25-electrum -l green watching-bitcoin` and `qvm-prefs -s watching-bitcoin netvm sys-whonix` in dom0.

Important Notes
---------------
* The private keys (xpriv) should never be moved outside of `offline-bitcoin`.
* For copying out the public keys (xpub), Qubes provides two secure, convenient
methods: the [inter-VM clipboard] and [inter-VM file copy] tools. Compared to
traditional physically air-gapped machines, these tools make it very easy to
copy out public keys.
