The Fuse archival node has a size of 2.5TB on Septmber 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

Not advised to allow all or unknown IP address to RPC port

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

Since 08.2022 Fuse is moving from OE client to . To bootstrap Fuse archive node this guide covers the steps on how to build Nethermind from source and configure it to run for Fuse Network

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

wget "$(curl -s https://api.github.com/repos/NethermindEth/nethermind/releases/latest \
        | grep "browser_download_url" \
        | grep "linux-x64.zip" \
        | cut -d '"' -f 4)" -O nethermind-latest-linux-x64.zip

Use unzip to extract downloaded archive

unzip nethermind-latest-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'

Create chainspec file for Fuse

mkdir -p /root/fuse-archive/chainspec

nano /root/fuse-archive/chainspec/fuse.json

Copy/Paste the following contents into the file:
