Validator Node Installation Instructions

This page provides step-by-step instructions for how to install a validator node in the Volta test network and the production Energy Web Chain network.

Good to know: The overall process of installing a validator node is identical on both the Volta test network and the main Energy Web Chain. The only difference is the installation script used in Step 2 - be sure that you use the correct installation script for the intended network!

We recommend using the Nethermind Validator Installation Script, as the OpenEthereum Client is no longer in development and has been deprecated. You can find the validator installation scripts here:

1. Volta:https://github.com/energywebfoundation/ewc-validator-node-install-scripts/tree/master/volta-affiliate/nethermind

2. EWC: https://github.com/energywebfoundation/ewc-validator-node-install-scripts/tree/master/ewc-affiliate/nethermind

1. Install the operating system and prepare the host machine according to the requirements (Step 1 in the previous checklist).

2. Select the correct Client installation script matching the desired network and installed OS on the energyweb github:

   • For the VOLTA TEST NETWORK: https://github.com/energywebfoundation/ewc-validator-node-install-scripts/tree/master/volta-affiliate, or copy the recommended client directory (Nethermind) from the volta-affiliate directory to the host

   • For the main ENERGY WEB CHAIN: https://github.com/energywebfoundation/ewc-validator-node-install-scripts/tree/master/ewc-affiliate, or copy the recommended client directory (Nethermind) from the ewc-affiliate directory to the host

3. Make sure the latest system updates are installed by running :

   • For Debian and Ubuntu:

     sudo apt-get update && sudo apt-get dist-upgrade

     For CentOS:

     sudo yum update

4. Make the script executable with

   chmod +x ./install-*.sh

5. Run the script (NOTE: please do not use the --auto parameter which can be used to take default for node-name and generate a random key).

6. If the installation was successful, it should generate a .txt file (named install-summary.txt) that lists the node address, IP address, and influxDB username/password. You will need to provide these details via a form in the next step to successfully add your validator node to the validator system contract.

   • If you encounter issues with the installation or the install-summary.txt file is not generated:

     1. First review any open issues on Github to see if there is a known issue.

     2. If the issue is not already known, submit a question in the #validators or #technical_questions channels in the EWF Member Slack space to troubleshoot.

7. Submit node installation details using the appropriate form below:

   1. For the VOLTA TEST NETWORK, enter details here.

   2. For the main ENERGY WEB CHAIN, enter details here.

8. After submitting the installation summary via the form, you will receive a confirmation email with next steps and links to helpful resources.
