# Sovran_SystemsOS

**A declarative, self-hosted operating system built on NixOS.**

---

## Overview

Sovran_SystemsOS is a fully integrated NixOS configuration that transforms a single machine into a personal cloud, communications hub, Bitcoin node, web server, and **daily-use desktop** — all managed declaratively.

Every service is pre-wired: reverse proxy routing, database initialization, firewall rules, automated backups, and inter-service communication are handled out of the box. Moreover, you can activate the other custom packages; the system does the rest.

---

## Architecture

Sovran_SystemsOS is structured as a set of NixOS modules exposed via a flake. A remote machine consumes the flake and selectively enables features through a simple configuration interface.

```

## Features

### Feature Toggles

[Custom Add-On Guide](custom-add-ons.md)

Every major service is gated behind a feature flag. Enable only what you need:

```nix
# custom.nix
{ config, pkgs, lib, ... }:

{
  
  sovran_systemsOS = {
    features = {
        bip110          = lib.mkForce true;
        element-calling = lib.mkForce true;
        haven           = lib.mkForce true;
        mempool         = lib.mkForce true;
        rdp             = lib.mkForce true;
    };
    nostr_npub = "pasteyournpubhere";
  };

}
```

No unnecessary services run. No wasted resources.

### Service Stack

| Category | Service | Description |
|---|---|---|
| **Web** | Caddy | Automatic HTTPS, reverse proxy for all services |
| **Cloud** | Nextcloud | File storage, sync, and collaboration |
| **CMS** | WordPress | Self-hosted publishing and content management |
| **Passwords** | Vaultwarden | Bitwarden-compatible password vault |
| **Messaging** | Element/Matrix Synapse | Federated, decentralized messaging backend |
| **Video/Voice Calling** | Element Video and Voice Calling | Decentralized Voice Over IP for Matrix with optional TURN/STUN |
| **Bitcoin** | Bitcoin Core / Knots | **Full node with optional BIP-110 consensus policy** |
| **Bitcoin Lightning** | LND Full node connected over TOR |
| **Payments** | BTCPay Server | Self-hosted Bitcoin payment processor |
| **Explorer** | Mempool | Bitcoin mempool visualizer and block explorer |
| **Nostr** | Haven | Nostr relay server |
| **Remote Access** | GNOME Remote Desktop | RDP access with auto-generated TLS and credentials |

---

### Security

- **SSH hardened** — password authentication disabled by default
- **Fail2ban** — active on https
- **Agenix** — encrypted secrets management integrated into the flake
- **Tor** — integration into the bitcoin ecosystem
- **Firewall** — ports managed per-module; only enabled services are exposed

### Reliability

- **Automated backups** via rsnapshot
- **Scheduled maintenance** via systemd timers
- **Database initialization** handled declaratively
- **Reproducible builds** — the entire system is defined in code and can be rebuilt or migrated to new hardware at any time

## Project Philosophy

Sovran_SystemsOS exists to provide a complete, self-hosted infrastructure stack that eliminates dependency on third-party platforms. It is opinionated by design — services are pre-integrated so you spend time using your system, not assembling it.

This is not a toolkit. It is a working system.

You retain full visibility into every module, every service definition, and every configuration choice. Nothing is hidden. Everything is reproducible.
