This module is outdated and incomplete. We can readd an improved version in the future. Move nanopos nginx proxy tests to the nanopos test.

nix-bitcoin is a collection of Nix packages and NixOS modules for easily installing **full-featured Bitcoin nodes** with an emphasis on **security**.
|
|
|
|
Overview
|
|
---
|
|
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.

Features
|
|
---
|
|
A [configuration preset](modules/presets/secure-node.nix) for setting up a secure node
|
|
* All applications use Tor for outbound connections and support accepting inbound connections via onion services.
|
|
* Includes a [nodeinfo](modules/nodeinfo.nix) script which prints basic info about the node.
|
|
|
|
NixOS modules
|
|
* Application services
|
|
* [bitcoind](https://github.com/bitcoin/bitcoin), with a default banlist against spy nodes
|
|
* [clightning](https://github.com/ElementsProject/lightning) with support for announcing an onion service\
|
|
Available plugins:
|
|
* [clboss](https://github.com/ZmnSCPxj/clboss): automated C-Lightning Node Manager
|
|
* [helpme](https://github.com/lightningd/plugins/tree/master/helpme): walks you through setting up a fresh c-lightning node
|
|
* [monitor](https://github.com/renepickhardt/plugins/tree/master/monitor): helps you analyze the health of your peers and channels
|
|
* [prometheus](https://github.com/lightningd/plugins/tree/master/prometheus): lightning node exporter for the prometheus timeseries server
|
|
* [rebalance](https://github.com/lightningd/plugins/tree/master/rebalance): keeps your channels balanced
|
|
* [summary](https://github.com/lightningd/plugins/tree/master/summary): print a nice summary of the node status
|
|
* [zmq](https://github.com/lightningd/plugins/tree/master/zmq): publishes notifications via ZeroMQ to configured endpoints
|
|
* [lnd](https://github.com/lightningnetwork/lnd) with support for announcing an onion service
|
|
* [spark-wallet](https://github.com/shesek/spark-wallet)
|
|
* [electrs](https://github.com/romanz/electrs)
|
|
* [btcpayserver](https://github.com/btcpayserver/btcpayserver)
|
|
* [liquid](https://github.com/elementsproject/elements)
|
|
* [Lightning Loop](https://github.com/lightninglabs/loop)
|
|
* [JoinMarket](https://github.com/joinmarket-org/joinmarket-clientserver)
|
|
* [recurring-donations](modules/recurring-donations.nix): for periodic lightning payments
|
|
* [bitcoin-core-hwi](https://github.com/bitcoin-core/HWI)
|
|
* Helper
|
|
* [netns-isolation](modules/netns-isolation.nix): isolates applications on the network-level via network namespaces
|
|
* [backups](modules/backups.nix): daily duplicity backups of all your node's important files
|
|
* [operator](modules/operator.nix): adds non-root user `operator` who has access to client tools (e.g. `bitcoin-cli`, `lightning-cli`)
|
|
|
|
Security
|
|
---
|
|
* **Simplicity:** Only services you select in `configuration.nix` and their dependencies are installed, packages and dependencies are [pinned](pkgs/nixpkgs-pinned.nix), most packages are built from the [NixOS stable channel](https://github.com/NixOS/nixpkgs/tree/nixos-20.09), with a few exceptions that are built from the nixpkgs unstable channel, builds happen in a [sandboxed environment](https://nixos.org/manual/nix/stable/#conf-sandbox), code is continuously reviewed and refined.
|
|
* **Integrity:** Nix package manager, NixOS and 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 options](modules/nix-bitcoin-services.nix), [RPC whitelisting](modules/bitcoind-rpc-public-whitelist.nix), and [netns-isolation](modules/netns-isolation.nix). There's a non-root user *operator* to interact with the various services.
|
|
* **Defense-in-depth:** nix-bitcoin is built with a [hardened kernel](https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/profiles/hardened.nix) by default, services are confined through discretionary access control, Linux namespaces, [dbus firewall](modules/security.nix) 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.
