You have the opportunity to engage with EigenLayer’s testnet in several capacities, including as a restaker, operator, or AVS Node Operator.

“Enhancing Ethereum’s Cryptoeconomic Security with EigenLayer’s Restaking Innovation” EigenLayer is a protocol built on Ethereum that introduces restaking, a new primitive in cryptoeconomic security. This primitive enables the rehypothetication of $ETH on the consensus layer. Users that stake $ETH can opt-in to EigenLayer smart contracts to restake their $ETH and extend cryptoeconomic security to additional applications on the network. Part of EigenLayer’s potential lies in its ability to aggregate and extend cryptoeconomic security through restaking and to validate new applications being built on top of Ethereum.

Order & Configure your VPS You can establish your node by either configuring it on a personal computer or by utilizing a Virtual Private Server (VPS), which is well-suited for managing websites, applications, or other internet-based services, including nodes.

For my setup, I selected Contabo, a well-regarded provider of VPS rentals. Opting for a plan with at least 100 GB of storage is advisable to ensure sufficient space for long-term node operation.

My suggestion would be to go for the Cloud VPS M or higher option. https://contabo.com/en/

Choose Cloud VPS M or Higher Select Payment Term Region — Germany Storage Type -400 GB SSD Image — Go to Apps & Panels > Docker

Apps & Panels > Docker 5. Log in & Set a Password for your Server

Set a password 6. Object Storage — Default 7. Networking — Default 8. Add-Ons — Default

After finalizing your payment, you’ll get an email verifying your purchase. Hold tight for a follow-up email, which will provide details about your VPS, encompassing your access credentials.

You’ll need to download and use Putty, a tool that enables you to securely connect to your VPS and utilize its functionalities. Download it here https://www.putty.org/

Enter IP ADDRESS Enter the VPS IP Address then Click OPEN Login : root Password: (Enter your chosen password)

Log in using the password you set earlier. Before Proceeding, you can check the official documentation here.

Preparations Install essential components sudo apt update && sudo apt upgrade -y 2. Install Essential Codes

sudo apt install pkg-config curl git-all build-essential libssl-dev libclang-dev ufw reply Y then proceed

1. Check if Docker is up-to-date / Docker Installation

docker version If docker is not installed, run the following command:

sudo apt-get install ca-certificates curl gnupg lsb-release Now add Docker’s official GPG key:

sudo mkdir -p /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg proceed… We Are to set up Repository: (just copy and paste)

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null Let’s grant Docker file permission just in case, before updating the package index

sudo chmod a+r /etc/apt/keyrings/docker.gpg sudo apt-get update after granting, updated index, Install latest version of docker

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin Now install Docker compose :

sudo apt install docker-compose

Press Y then ENTER Lets verify the ENGINE INSTALLATION is successful by running the hello-world

sudo docker run hello-world You should get this.

Now check Docker compose version :

docker-compose -v

Part 1: Node Installation

1. Let’s Install SCREEN sudo apt install screen Create new screen session

sudo screen -S Eigenlayer 2. GO LANGUAGE INSTALLATION a. Install

wget https://golang.org/dl/go1.21.4.linux-amd64.tar.gz

b. Extract folder

tar -C /usr/local -xzf go1.21.4.linux-amd64.tar.gz

c. Add Go to your Environment

export PATH=$PATH:/usr/local/go/bin

d. Verify Go bin installation

go version

1. Install CLI from Source a. Install github eigenlayer

git clone https://github.com/Layr-Labs/eigenlayer-cli.git cd eigenlayer-cli mkdir -p build go build -o build/eigenlayer cmd/eigenlayer/main.go

b. Copy file into the system

cp ./build/eigenlayer /usr/local/bin/

c. Verify if Eigen is properly installed

eigenlayer

1. Create and List Keys a. Create Keys

eigenlayer operator keys create --key-type ecdsa [keyname] eigenlayer operator keys create --key-type bls [keyname] example:

eigenlayer operator keys create --key-type ecdsa EkkoNodes eigenlayer operator keys create --key-type bls EkkoNodes [keyname] — This will be the name of the created key file

This will prompt a password which you can use to encrypt the keys. Keys will be stored in a local disk and will be shown once keys are created. It will also show the private key only once, so that you can back it up in case you lose the password or key file. Make sure to Backup your keys. You can only see this once.

b. View Keys

Verify Operator status eigenlayer operator status operator.yaml or you can view it on the website here (will appear after a few mins) Part 2: EigenLayer AVS Operator Now that your operator is registered on Eigenlayer, you can launch the Eigenlayer node. You will need to have 32 gETH and enough restaked gETH on your operator to rank among the top 200 validator nodes. WARNING: As of this writing you will need at least 18,000 gEth restaked to your operator to be on the EigenDA AVS Operator.
