A collection of Nix packages and NixOS modules for easily installing full-featured Bitcoin nodes with an emphasis on security.
nix-bitcoin is a collection of Nix packages and NixOS modules for easily installing full-featured Bitcoin nodes with an emphasis on security.
A Bitcoin node verifies the Bitcoin protocol and provides ways of interacting with the Bitcoin network. nix-bitcoin nodes are used for a variety of purposes and can serve as personal or merchant wallets, second layer public infrastructure and as backends for Bitcoin applications. 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.
A full installation of nix-bitcoin is usually deployed either on a dedicated (virtual) machine or runs in a container and is online 24/7. Alternatively, the Nix packages, NixOS modules and configurations 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.
See here for examples.

configuration.nixand their dependencies are installed, packages and dependencies are pinned, support for doas (sudo alternative), most packages are built from the NixOS stable channel, with a few exceptions that are built from the nixpkgs unstable channel, builds happen in a sandboxed environment, code is continuously reviewed and refined.
Note that if the machine you're deploying from is insecure, there is nothing nix-bitcoin can do to protect itself.
