BEFORE YOU START THIS PROCEDURE - Make sure the button "Become a Validator" is available on

Create an EtherLite validator node on VULTR or DIGITAL OCEAN or any root access server supporting Ubuntu 20.04

Watch full video procedure on coming soon


You are now ready to configure your Server!

Recommended Server Size: 2 CPU Premium Intel/AMD (DIGITAL OCEAN) or High Frequency (VULTR) with 2GB of RAM and 60+GB SSD. Note that you will have to Resize/Upgrade your Droplet/Server over time as the Blockchain will increase in size as well as the number of transactions per block.

  1. Update and Upgrade your server.

    sudo apt-get update
    sudo apt-get upgrade
  2. Sync Clock:

    Your clock should by synchronized to prevent skipping block sealing.

    Enter timedatectl status , you should see similar output:

    Local time: Tue 2020-06-30 17:16:19 UTC
    Universal time: Tue 2020-06-30 17:16:19 UTC
    RTC time: Tue 2020-06-30 17:16:19
    Time zone: Etc/UTC (UTC, +0000)
    System clock synchronized: yes
    systemd-timesyncd.service active: yes
    RTC in local TZ: no

    If System clock synchronized displays yes and Time zone is set to UTC, proceed to step 3.

    If not, get help here:

  3. Clone this repo:

    git clone
    cd validator-node-screen
  4. Download OpenEthereum.

    curl -SfL "" -o
  5. Install unzip.

    apt install -y unzip
  6. Unzip the OpenEthereum zip

  7. Give proper permission to run the file

    chmod +x openethereum
  8. Download the genesis file of EtherLite

    curl -SfL '' -o genesis.json
  9. Create password file for Validator account.

    echo "YOUR-VAL-UNIQUE-PASS" > password
  10. Create your Validator account address

    ./openethereum account new --keys-path=data/keys --password=password --chain=genesis.json

    Save the return address for next stept

  11. Update node.toml file. There are a few settings you need to define:

    nano node.toml
    Update Parameter below.
    unlock = [""]
    engine_signer = ""
    • Line 31 unlock - Your account address (with leading 0x).
    • Line 33 engine_signer - Your account address (with leading 0x).

    After Adding your validator address Press CTRL+X you will be asked if you want to save. Enter Y and Press Enter.

  12. (RECOMMENDED BUT OPTIONAL) Download a Blockchain snapshot for faster initial sync. Save 3+ hours of sync.

    Since synchronizing the blockchain can take many hours at this point, I decided to make a snapshot (around block height 3,748,000) so you can synchronize faster when setting up a new node - your node will only have to sync blocks made after that point. Make sure you are still in ~/validator-node-screen# directory before unziping.

    curl -L "" -o

    NOTE: This file is 1.6 GB, download time may differ depending on your server performance and connection (usually under 30 seconds) this will save you 3+ hours of sync. The snapshot file is located on my personal high-speed space Digital Ocean paying account for better download performance speed.

  13. Start your node.

    screen -S node
    ./openethereum --config=node.toml --jsonrpc-port=8545 --jsonrpc-cors=all --jsonrpc-interface=all --jsonrpc-hosts=all --jsonrpc-apis=web3,eth,net,parity --ws-interface=all --ws-apis=web3,eth,net,parity,pubsub --ws-origins=all --ws-hosts=all --ws-max-connections=10 --max-peers=100

    The node will sync with the chain (may take a while).

    To safely minimize Screen by entering (CTRL+a+d)

  14. Check if sync is completed.

    curl --data '{"method":"eth_syncing","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:8545

    This is what you're waiting to see: {"jsonrpc":"2.0","result":false,"id":1}

  15. (OPTIONAL SCREEN COMMAND) If you need to Stop your node.

    First you need to find your Screen ID

    screen -list

    You will get back something like below.

    There is a screen on: 5182.node (10/16/2021 03:02:40 PM) (Detached) 1 Socket in /run/screen/S-root.

    Your Screen ID is 5182.node. (replace 5182 with your ID)

    screen -X -S "5182.node" quit

    Or if you just want to get back to monitor your node. (replace 5182 with your ID)

    screen -r 5182.node
  16. Security.

    There is no need to setup a UFW firewall (There are too many ports to allow for communication between nodes)

    So make sure it is Offline. (There is nothing of value anyway, unless you are running other scripts with your EtherLite Node, Not recommended)

    sudo ufw status

    You should get "Status: inactive"

    If not type:

    sudo ufw disable

    (Optional) We recommend you to install Fail2ban to avoid brute force attack.

  17. Setup Monitoring with a crontab entry. If your node go offline, it will restart automatically. (NOTE: FOR crontab -e "select NANO 1")

    sudo chmod 755 /root/validator-node-screen/cron/
    crontab -e
    Add this line to the end of the file plus(+) a carriage return(blank line). save and exit.
    * * * * * $HOME/validator-node-screen/cron/ > $HOME/validator-node-screen/cron/watchdognode.log 2>&1

    After Adding the cron line Press CTRL+X you will be asked if you want to save. Enter Y and Press Enter.

    (Optional) Monitor all your nodes with Site24x7. Receive Server Down, Critical or Trouble SMS/eMail alerts.

  18. Double check if your validator node is working after ReBooting before you submit it to

    sudo reboot

    Wait 2 minutes before login back in your server.

    curl --data '{"method":"eth_syncing","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:8545

    Again, This is what you're waiting to see: {"jsonrpc":"2.0","result":false,"id":1}

    Next test if RPC communication is enabled with your server, type http://YOUR-EXTERNAL-IP-ADDRES:8545 in any web browser.

    This is the message you're waiting to see: Used HTTP Method is not allowed. POST or OPTIONS is required

    Now you are ready to got to Just click the Become a Candidate Button and fill up the form.

    All done now! You are now a Validator Node Master...
