Updating --- In your deployment directory, enter the nix shell with `nix-shell` and run ``` fetch-release > nix-bitcoin-release.nix ``` Nodeinfo --- Run `nodeinfo` to see your onion addresses for the webindex, spark, etc. if they are enabled. Connect to spark-wallet --- ### Requirements * Android phone * [Orbot](https://guardianproject.info/apps/orbot/) installed from [F-Droid](https://guardianproject.info/fdroid) (recommended) or [Google Play](https://play.google.com/store/apps/details?id=org.torproject.android&hl=en) * [Spark-wallet](https://github.com/shesek/spark-wallet) installed from [direct download](https://github.com/shesek/spark-wallet/releases) or [Google Play](https://play.google.com/store/apps/details?id=com.spark.wallet) 1. Enable spark-wallet in `configuration.nix` Change ``` # services.spark-wallet.enable = true; ``` to ``` services.spark-wallet.enable = true; ``` 2. Deploy new `configuration.nix` ``` nixops deploy -d bitcoin-node ``` 3. Enable Orbot VPN for spark-wallet ``` Open Orbot app Turn on "VPN Mode" Select Gear icon under "Tor-Enabled Apps" Toggle checkbox under Spark icon ``` 4. Get the onion address, access key and QR access code for the spark wallet android app ``` journalctl -eu spark-wallet ``` Note: The qr code might have issues scanning if you have a light terminal theme. Try setting it to dark or highlighting the entire output to invert the colors. 5. Connect to spark-wallet android app ``` Server Settings Scan QR Done ``` Connect to electrs --- ### Requirements Android * Android phone * [Orbot](https://guardianproject.info/apps/orbot/) installed from [F-Droid](https://guardianproject.info/fdroid) (recommended) or [Google Play](https://play.google.com/store/apps/details?id=org.torproject.android&hl=en) * [Electrum mobile app](https://electrum.org/#home) 4.0.1 and newer installed from [direct download](https://electrum.org/#download) or [Google Play](https://play.google.com/store/apps/details?id=org.electrum.electrum) ### Requirements Desktop * [Tor](https://www.torproject.org/) installed from [source](https://www.torproject.org/docs/tor-doc-unix.html.en) or [repository](https://www.torproject.org/docs/debian.html.en) * [Electrum](https://electrum.org/#download) installed 1. Enable electrs in `configuration.nix` Change ``` # services.electrs.enable = true; ``` to ``` services.electrs.enable = true; ``` 2. Deploy new `configuration.nix` ``` nixops deploy -d bitcoin-node ``` 3. Get electrs onion address ``` nodeinfo | grep 'ELECTRS_ONION' ``` 4. Connect to electrs Make sure Tor is running on Desktop or as Orbot on Android. On Desktop ``` electrum --oneserver -1 -s ":50001:t" -p socks5:localhost:9050 ``` On Android ``` Three dots in the upper-right-hand corner Network > Proxy mode: socks5, Host: 127.0.0.1, Port: 9050 Network > Auto-connect: OFF Network > One-server mode: ON Network > Server: :50001:t ``` Connect to nix-bitcoin node through ssh Tor Hidden Service --- 1. Run `nodeinfo` on your nix-bitcoin node and note the `SSHD_ONION` ``` nixops ssh operator@bitcoin-node nodeinfo | grep 'SSHD_ONION' ``` 2. Create a SSH key ``` ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519 ``` 3. Place the ed25519 key's fingerprint in the `configuration.nix` `openssh.authorizedKeys.keys` field like so ``` # FIXME: Add your SSH pubkey services.openssh.enable = true; users.users.root = { openssh.authorizedKeys.keys = [ "[contents of ~/.ssh/id_ed25519.pub]" ]; }; ``` 4. Connect to your nix-bitcoin node's ssh Tor Hidden Service, forwarding a local port to the nix-bitcoin node's ssh server ``` ssh -i ~/.ssh/id_ed25519 -L [random port of your choosing]:localhost:22 root@[your SSHD_ONION] ``` 5. Edit your `network-nixos.nix` to look like this ``` { bitcoin-node = { config, pkgs, ... }: { deployment.targetHost = "127.0.0.1"; deployment.targetPort = [random port of your choosing]; }; } ``` 6. Now you can run `nixops deploy -d bitcoin-node` and it will connect through the ssh tunnel you established in step iv. This also allows you to do more complex ssh setups that `nixops ssh` doesn't support. An example would be authenticating with [Trezor's ssh agent](https://github.com/romanz/trezor-agent), which provides extra security. Initialize a Trezor for Bitcoin Core's Hardware Wallet Interface --- 1. Enable Trezor in `configuration.nix` Change ``` # services.hardware-wallets.trezor = true; ``` to ``` services.hardware-wallets.trezor = true; ``` 2. Deploy new `configuration.nix` ``` nixops deploy -d bitcoin-node ``` 3. Check that your nix-bitcoin node recognizes your Trezor ``` nixops ssh operator@bitcoin-node lsusb ``` Should show something relating to your Trezor 4. If your Trezor has outdated firmware or is not yet initialized: Start your Trezor in bootloader mode Trezor v1 ``` Plug in your Trezor with both buttons depressed ``` Trezor v2 ``` Start swiping your finger across your Trezor's touchscreen and plug in the USB cable when your finger is halfway through ``` 5. If your Trezor's firmware is outdated: Update your Trezor's firmware ``` trezorctl firmware-update ``` Follow the on-screen instructions **Caution: This command _will_ wipe your Trezor. If you already store Bitcoin on it, only do this with the recovery seed nearby.** 6. If your Trezor is not yet initialized: Set up your Trezor ``` trezorctl reset-device -p ``` Follow the on-screen instructions 7. Find your Trezor ``` hwi enumerate hwi -t trezor -d promptpin hwi -t trezor -d sendpin hwi enumerate ``` 8. Follow Bitcoin Core's instructions on [Using Bitcoin Core with Hardware Wallets](https://github.com/bitcoin-core/HWI/blob/master/docs/bitcoin-core-usage.md) to use your Trezor with `bitcoin-cli` on your nix-bitcoin node
