# How to self-host hardened Bitcoin node
## Requirements
- [Hardened Debian server](../how-to-configure-hardened-debian-server) or [hardened Raspberry Pi](../how-to-configure-hardened-raspberry-pi) (with at least 4GB of RAM, 1TB of SSD storage and IPv6 disabled)
- Linux or macOS computer
## Caveats
- When copy/pasting commands that start with `$`, strip out `$` as this character is not part of the command
- When copy/pasting commands that start with `cat << "EOF"`, select all lines at once (from `cat << "EOF"` to `EOF` inclusively) as they are part of the same (single) command
## Setup guide
### Step 1: log in to server or Raspberry Pi
> Heads-up: replace `~/.ssh/pi` with path to private key and `pi-admin@10.0.1.94` with server or Raspberry Pi SSH destination.
```shell
ssh -i ~/.ssh/pi pi-admin@10.0.1.94
```
### Step 2: install dependencies
> Heads-up: if `sudo: command not found` is thrown, use `su -` instead.
```console
$ sudo su -
$ apt update
$ apt install -y apt-transport-https build-essential clang cmake curl git gnupg sudo
```
### Step 3: add user to sudo group
> Heads-up: replace `pi-admin` with user.
```shell
usermod -aG sudo pi-admin
```
### Step 4: log out and log in to enable sudo privileges
> Heads-up: replace `~/.ssh/pi` with path to private key and `pi-admin@10.0.1.94` with server or Raspberry Pi SSH destination.
```console
$ exit
$ exit
$ ssh -i ~/.ssh/pi pi-admin@10.0.1.94
$ sudo su -
```
### Step 5: install and configure [WireGuard](https://www.wireguard.com/)
#### Install WireGuard
```console
$ apt update
$ apt install -y openresolv wireguard
```
#### Create and fund [Mullvad](https://mullvad.net/en/) account and [generate](https://mullvad.net/en/account/#/wireguard-config/) WireGuard config
> Heads-up: replace `ca-mtr-wg-101.conf` with Mullvad endpoint, paste Mullvad WireGuard config into `/etc/wireguard/$MULLVAD_ENDPOINT.conf`.
```console
$ MULLVAD_ENDPOINT=ca-mtr-wg-101
$ nano /etc/wireguard/$MULLVAD_ENDPOINT.conf
$ sed -i -E 's/^(Address.*?),.*/\1/' /etc/wireguard/*.conf
$ sed -i -E 's/^(AllowedIPs.*?),.*/\1/' /etc/wireguard/*.conf
```
#### Enable IP forwarding and configure firewall kill switch
> Heads-up: replace `eth0` with network interface (run `ip a` to find interface).
```console
$ NETWORK_INTERFACE=eth0
$ sed -i -E 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
$ sysctl -p
$ cat << EOF > /etc/nftables.conf
#!/usr/sbin/nft -f
flush ruleset
table ip firewall {
chain input {
type filter hook input priority filter; policy drop;
iif "lo" accept
iif != "lo" ip daddr 127.0.0.0/8 drop
iifname "$NETWORK_INTERFACE" tcp dport 22 accept
ct state established,related accept
}
chain forward {
type filter hook forward priority filter; policy drop;
}
chain output {
type filter hook output priority filter; policy drop;
oif "lo" accept
oifname "$NETWORK_INTERFACE" udp dport 51820 accept
oifname "$MULLVAD_ENDPOINT" tcp dport { 80, 443 } accept
oifname "$MULLVAD_ENDPOINT" udp dport { 53, 123 } accept
ct state established,related accept
}
}
table ip6 firewall {
chain input {
type filter hook input priority filter; policy drop;
}
chain forward {
type filter hook forward priority filter; policy drop;
}
chain output {
type filter hook output priority filter; policy drop;
}
}
EOF
$ nft -f /etc/nftables.conf
```
#### Enable and start WireGuard
```console
$ systemctl enable wg-quick@$MULLVAD_ENDPOINT
$ systemctl start wg-quick@$MULLVAD_ENDPOINT
$ curl https://am.i.mullvad.net/connected
You are connected to Mullvad (server ca-mtr-wg-101). Your IP address is 89.36.78.153
```
You are connected to Mullvad
👍
### Step 6: install [Cargo](https://doc.rust-lang.org/cargo/index.html)
```console
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
info: downloading installer
Welcome to Rust!
This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.
Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:
/root/.rustup
This can be modified with the RUSTUP_HOME environment variable.
The Cargo home directory located at:
/root/.cargo
This can be modified with the CARGO_HOME environment variable.
The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:
/root/.cargo/bin
This path will then be added to your PATH environment variable by
modifying the profile files located at:
/root/.profile
/root/.bashrc
You can uninstall at any time with rustup self uninstall and
these changes will be reverted.
Current installation options:
default host triple: aarch64-unknown-linux-gnu
default toolchain: stable (default)
profile: default
modify PATH variable: yes
1) Proceed with installation (default)
2) Customize installation
3) Cancel installation
>1
…
Rust is installed now. Great!
To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).
To configure your current shell, run:
source $HOME/.cargo/env
$ source $HOME/.cargo/env
```
### Step 7: import Sun’s PGP public key (used to verify downloads below)
```console
$ curl --fail https://sunknudsen.com/sunknudsen.asc | gpg --import

### Step 17: watch initial block download
> Heads-up: initial block download will likely take more than a week on Raspberry Pi.
```console
$ sudo -u bitcoin watch bitcoin-cli -datadir=/var/lib/bitcoind getblockchaininfo
Every 2.0s: bitcoin-cli -datadir=/var/lib/bitcoind getblockchaininfo

### Step 19: install [electrs](https://github.com/romanz/electrs) (see [docs](https://github.com/romanz/electrs/blob/master/doc/install.md))
> Heads-up: build will likely take more than half an hour on Raspberry Pi.
```console
$ git clone https://github.com/romanz/electrs

…
Finished release [optimized] target(s) in 24m 18s
$ cp target/release/electrs /usr/bin/
$ systemctl enable electrs
$ systemctl start electrs
$ cd

### Step 20: watch initial sync
> Heads-up: initial sync will likely take more than a day on Raspberry Pi.
> Heads-up: run following commands concurrently.
```console

## Upgrade guide
### Step 1: log in to server or Raspberry Pi
> Heads-up: replace `~/.ssh/pi` with path to private key and `pi-admin@10.0.1.94` with server or Raspberry Pi SSH destination.
```shell
ssh -i ~/.ssh/pi pi-admin@10.0.1.94
```
### Step 2: stop Bitcoin Core and electrs
```console
$ sudo su -
$ systemctl stop bitcoind
$ systemctl stop electrs
```
### Step 3: upgrade dependencies
```console
$ apt update
$ apt upgrade --yes
```
### Step 4: upgrade Bitcoin Core
> Heads-up: replace `24.0.1` with [latest release](https://bitcoincore.org/en/releases/) semver.
