* **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.
* **Principle of Least Privilege:** Services operate with least privileges; they each have their own user and are restricted further with [systemd options](pkgs/lib.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.

Change
```
# services.lnd.restOnionService.enable = true;
```
to
```
services.lnd.restOnionService.enable = true;
```
2. Deploy new `configuration.nix`
```
nixops deploy -d bitcoin-node
```
3. Run command `lndconnect-rest-onion` (under `operator` user) to create a QR code for
connecting to LND via the REST onion service.
4. Enable Orbot VPN for Zeus
```
Open Orbot app
Turn on "VPN Mode"
Select Gear icon under "Tor-Enabled Apps"
Toggle checkbox under Zeus icon
