Setup Nodes

Install docker

If you have ever participated in Q-Blockchain and other testnet nodes, chances are you have already installed Docker, so you can skip this step.

1. Update apt-get and install the required packages

   sudo apt-get update
   sudo apt-get install \
     ca-certificates \
     curl \
     gnupg \
     lsb-release
2. Add the docker 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
3. Setup the repository

   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
4. Install docker

   sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
5. Check if Docker is installed correctly

   sudo docker run hello-world

Install Nodes

1. Download Nodes

   wget https://dub.sh/linuxamd64 -O ~/bin/stader-cli

2. Go to the bin directory

   cd $HOME/bin

3. Convert the file to executable

   chmod +x ~/bin/stader-cli

4. Restart the terminal

   bash

5. Install services

   stader-cli --allow-root service install

1. Make sure your Node is in sync

   stader-cli --allow-root node sync

   If the output is like this, it means that your node has synced

   Your primary execution client is fully synced.
   Your primary consensus client is fully synced.

2. Create a wallet

   5. Paste the mnemonic in the order (per word)
   6. Copy the node key

3. Claim faucets

   1. Join the [discord] server(https://discord.gg/staderlabs)

   2. Go to channel #ethxclusives-permissionless-node-operators

   3. Send chat !interested

   4. Wait until you are approved to be a beta tester

   5. Go to channel #ethx-rolling-beta-test

   6. Paste your Node key (don't spam, just once), for example

      Your Stader Node is currently using the Goerli Test Network.
      
      The node wallet is initialized.
      Account nodes: 0x000000000000000000000000000000000000000

4. List of validators console stader-cli --allow-root node register --on <MONIKER> Gas price enter 800-900 gwei

       Change the moniker up to you, for example:
   
       ```console
       stader-cli --allow-root node register --on node123
       ```
   
   5.SD deposits
   `console

   stader-cli --allow-root node deposit-sd --amount 640 ` Gas price enter 800-900 gwei

5. Deposit 4ETH

   stader-cli --allow-root node deposit --num-validators 1

   Gas price enter 800-900 gwei

6. Check status

   stader-cli --allow-root node status

   It will output like this later

   === Operator Registration Details ===
   The node is registered with Stader. Below are node details:
   Opauthor Id: xxx
   
   OperatorName: xxxxx
   
   Operator Reward Address: 0x000000000000000000000000000000000000000
