nix-bitcoin is a collection of Nix packages and NixOS modules for easily installing full-featured Bitcoin nodes with an emphasis on security.
Overview
nix-bitcoin can be used for personal or merchant wallets, public infrastructure or for Bitcoin application backends. In all cases, the aim is to provide security and privacy by default. However, while nix-bitcoin is used in production today, it is still considered experimental.
nix-bitcoin nodes can be deployed on dedicated hardware, virtual machines or containers. The Nix packages and NixOS modules can be used independently and combined freely.
nix-bitcoin is built on top of Nix and NixOS which provide powerful abstractions to keep it highly customizable and maintainable. Testament to this are nix-bitcoin's robust security features and its potent test framework. However, running nix-bitcoin does not require any previous experience with the Nix ecosystem.
Get started
- See the examples for an overview of all features.
- To setup a new node from scratch, see the installation instructions.
- To add nix-bitcoin to an existing NixOS configuration, see importable-configuration.nix and the Flake example.

- backups: duplicity backups of all your node's important files
- operator: adds non-root user
operator
who has access to client tools (e.g.bitcoin-cli
,lightning-cli
)
Security
See SECURITY.md for the security policy and how to report a vulnerability.
nix-bitcoin aims to achieve a high degree of security by building on the following principles:
- Simplicity: Only services enabled in
configuration.nix
and their dependencies are installed, support for doas (sudo alternative), code is continuously reviewed and refined. - Integrity: The Nix package manager guarantees that all dependencies are exactly specified, packages can be built from source to reduce reliance on binary caches, nix-bitcoin merge commits are signed, all commits are approved by multiple nix-bitcoin developers, upstream packages are cryptographically verified where possible, we use this software ourselves.
- Principle of Least Privilege: Services operate with least privileges; they each have their own user and are restricted further with systemd features, RPC whitelisting and netns-isolation. There's a non-root user operator to interact with the various services.
- Defense-in-depth: nix-bitcoin supports a hardened kernel, services are confined through discretionary access control, Linux namespaces, dbus firewall and seccomp-bpf with continuous improvements.
Note that if the machine you're deploying from is insecure, there is nothing nix-bitcoin can do to protect itself.
Security fund
The nix-bitcoin security fund is a 2 of 3 bitcoin multisig address open for donations, used to reward
security researchers who discover vulnerabilities in nix-bitcoin or its upstream dependencies.
See Security Fund for details.
Developing
See dev/README.
Troubleshooting
If you are having problems with nix-bitcoin check the FAQ or submit an issue.
There's also a Matrix room at #general:nixbitcoin.org
and a #nix-bitcoin
IRC channel on libera.
We are always happy to help.
