The default configuration sets up a Bitcoin Core node and c-lightning. The user can enable spark-wallet in `configuration.nix` to make c-lightning accessible with a smartphone using spark-wallet.
A simple webpage shows the lightning nodeid and links to nanopos letting the user receive donations.
It also includes liquid-daemon.
It also includes elements-daemon.
Outbound peer-to-peer traffic is forced through Tor, and listening services are bound to onion addresses.
A demo installation is running at [http://6tr4dg3f2oa7slotdjp4syvnzzcry2lqqlcvqkfxdavxo6jsuxwqpxad.onion](http://6tr4dg3f2oa7slotdjp4syvnzzcry2lqqlcvqkfxdavxo6jsuxwqpxad.onion).
