Walks through using nixOS + Nix package manager to make full-node operation reproducible and auditable: a single nix-bitcoin config file configuration.nix flips on services, builds deterministic derivations, and supports rollbacks. Shows running bitcoind, lnd, electrs, c-lightning, joinmarket and Liquid behind Tor with hardened systemd units, namespaces and least-privilege profiles; nodes run on Raspberry Pi, Intel NUC, old MacBook or Surface and avoid a noted pseudo‑vulnerability, so the setup actually works at scale.
