Nix packages and nixos modules for easily installing Bitcoin nodes and higher layer protocols. This is a work in progress - don't expect it to be bug free or secure.
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.
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. The following screen cast shows a fresh deployment of a nix-bitcoin node.
The goal is to make it easy to deploy a reasonably secure Bitcoin node with a usable wallet. It should allow managing bitcoin (the currency) effectively and providing public infrastructure. It should be a reproducible and extensible platform for applications building on Bitcoin.
By default the configuration.nix
provides:
- bitcoind (pruned) with outbound connections through Tor and inbound connections through a hidden service. By default loaded with banlist of spy nodes.
- clightning with outbound connections through Tor, not listening
- includes "nodeinfo" script which prints basic info about the node
- adds non-root user "operator" which has access to bitcoin-cli and lightning-cli
In configuration.nix
the user can enable:
- a clightning hidden service
- liquid-daemon
- lightning charge
- nanopos
- an index page using nginx to display node information and link to nanopos
- spark-wallet
- electrs
- recurring-donations, a module to repeatedly send lightning payments to recipients specified in the configuration.
The data directories of the services can be found in /var/lib
on the deployed machines.
The easiest way is to run nix-shell
(on a Linux machine) in the nix-bitcoin directory and then create a NixOps deployment with the provided network.nix
in the network
directory.
Fix the FIXMEs in configuration.nix and deploy with nixops in nix-shell.
See install.md for a detailed tutorial.
- Disk space: 300 GB (235GB for Bitcoin blockchain + some room)
- Bitcoin Core pruning is not supported at the moment because it's not supported by c-lightning. It's possible to use pruning but you need to know what you're doing.
- RAM: 2GB of memory
Tested hardware includes pcengine's apu2c4
For usage instructions, such as how to connect to spark-wallet, electrs and the ssh Tor Hidden Service, see usage.md.
