The Fuse archival node has a size of 2.4TB on July 3rd, 2024

Pre-Requisites

sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y

sudo apt install -y git make wget gcc pkg-config libusb-1.0-0-dev libudev-dev jq gcc g++ curl libssl-dev screen apache2-utils build-essential pkg-config unzip

Setting up Firewall

Set explicit default UFW rules

sudo ufw default deny incoming
sudo ufw default allow outgoing

Allow SSH

sudo ufw allow 22/tcp

Allow remote RPC connections with Fuse node

sudo ufw allow from ${REMOTE.HOST.IP} to any port 8545 8546

Allow P2P Connections

sudo ufw allow 30303/tcp
sudo ufw allow 30303/udp

Enable Firewall

sudo ufw enable

To check the status of UFW and see the current rules

sudo ufw status verbose

Building a Node on Fuse with Nethermind client

Install .NET SDK

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt update
sudo apt install -y apt-transport-https
sudo apt update
sudo apt install -y dotnet-sdk-8.0

Download the Latest Nethermind Release Binary

Check release binary page and take the following steps to download the latest Nethermind version:

Create a directory to store the binary and chain data (you might need sudo)

mkdir fuse-archive

Use wget to grab the latest release binary archive and output it to the directory created in the previous step:

wget https://github.com/NethermindEth/nethermind/releases/download/1.27.0/nethermind-1.27.0-220b5b85-linux-x64.zip \
-O /root/fuse-archive/ nethermind-1.27.0-220b5b85-linux-x64.zip

Use unzip to extract downloaded archive

unzip nethermind-1.27.0-220b5b85-linux-x64.zip

Configuing Nethermind client

Increase the maximum number of open files

sudo bash -c 'echo "nethermind soft nofile 100000" > /etc/security/limits.d/nethermind.conf' 
sudo bash -c 'echo "nethermind hard nofile 100000" >> /etc/security/limits.d/nethermind.conf'

Download chainspec file for Fuse

mkdir -p /root/fuse-archive/chainspec

wget https://raw.githubusercontent.com/fuseio/nethermind-client/refs/heads/production/src/Nethermind/Chains/fuse.json

The contents of the fuse.json file should be like this:

Create Data Directory to store chain data for Fuse blockchain

mkdir /root/fuse-archive/fuse_data

Configure systemd Service

Ensure that you grant execute permission to the binary file:

sudo chmod +x /root/fuse-archive/Nethermind.Runner

Create a systemd service file:

sudo nano /etc/systemd/system/nethermind.service

Add the following content:

[Unit]
Description=Nethermind Node
Documentation=https://docs.nethermind.io
After=network.target

[Service]

Reload systemd and Enable the Service

systemctl enable nethermind #enable nethermind service at system startup

sudo systemctl daemon-reload #refresh systemd configuration when changes made

sudo systemctl start nethermind #start nethermind

sudo systemctl stop nethermind #stop nethermind

To check or modify nethermind.service parameters simply run

sudo nano /etc/systemd/system/nethermind.service

Ctrl+X and Y to save changes

View Logs for Debugging

journalctl -f -u nethermind  #follow logs of nethermind service

The logs should look like below and indicate that your node syncs and is expected to reach a chainhead in ~2-3 days
