Erigon 🦦

Official Docs https://erigon.gitbook.io/

Pre-requisites

Update, upgrade, and clean the system, and then install essential development tools (build-essential), firewall management (ufw), and the Git version control system.

sudo apt update -y && sudo apt upgrade -y && sudo apt auto-remove -y
sudo apt-get install -y build-essential ufw git cmake

Set explicit default UFW rules

sudo ufw default deny incoming
sudo ufw default allow outgoing

Allow P2P connections with Erigon, Consensus peers and SSH

sudo ufw allow 30303
sudo ufw allow 9001
sudo ufw allow 22/tcp

Allow remote RPC connections with Execution Client

sudo ufw allow from ${REMOTE.HOST.IP} to any port 9656

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

Enable Firewall

sudo ufw enable

Install go

Download the Go programming language distribution archive, extracts it to the "/usr/local" directory, and then removes the downloaded archive, effectively installing Go version 1.20.6 on the system.

wget https://go.dev/dl/go1.20.6.linux-amd64.tar.gz && \
rm -rf /usr/local/go && \
tar -C /usr/local -xzf go1.20.6.linux-amd64.tar.gz && \
rm go1.20.6.linux-amd64.tar.gz

Please add the Go executable path to your system's PATH environment variable, and then test to ensure that Go is working correctly.

echo "export PATH="$PATH:/root/.foundry/bin:/usr/local/go/bin"" >> /root/.bashrc
source /root/.bashrc
go version #test

Create Erigon Directory

Create a new directory named erigon within the "/root/.local/share" directory, providing a location for storing data related to Erigon.

mkdir /root/.local/share/erigon

Generate JWT token

Generate a 32-byte random hexadecimal value using OpenSSL, removes any newline characters, and then save the result into the file "jwt.hex" located in the "/root/.local/share/erigon/" directory.

openssl rand -hex 32 | sudo tee /root/.local/share/erigon/jwt.hex > /dev/null

Build Erigon

Clone the Erigon repository from GitHub, including its submodules, changes the current directory to the Erigon directory, checks out the latest release tag, and then compile the project using the "make" build system.

git clone --recurse-submodules https://github.com/ledgerwatch/erigon.git
cd erigon
git checkout <latest release tag>
make

Configure Erigon

Append a systemd service configuration for the Erigon Gnosis Mainnet Service to the "/etc/systemd/system/erigon.service" file, specifying its description, dependencies, and executable parameters for proper execution and monitoring.

sudo echo "[Unit]

Run Erigon

Reload the systemd manager configuration, start the Erigon service, and enable it to start automatically on system boot, ensuring that the Erigon Gnosis Mainnet Service is active and will be automatically started upon system startup.

sudo systemctl daemon-reload
sudo systemctl start erigon
sudo systemctl enable erigon

Monitor Logs

Use journalctl to display real-time log messages and continuously follow the log output of the Erigon service, allowing you to monitor its activity and troubleshoot any issues as they occur.

sudo journalctl -fu erigon

Consensus Clients

For Erigon to operate, it requires the use of a consensus client. It is crucial to consider client diversity while doing so. -> https://clientdiversity.org/

Nimbus ☁️

Official Docs https://nimbus.guide/index.html

Install cmake

sudo apt -y install cmake

Create Nimbus Directory

Create a new directory named nimbus within the "/root/.local/share" directory, providing a location for storing data related to Nimbus.
