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 Nethermind. 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

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'

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:
