How to Run Harmony Node?

Participate in the Harmony blockchain network by running a Harmony node and contribute to the DeFi ecosystem. It doesn’t really matter who you are – all it takes is interest, some level of technical expertise, some gear. Through this guide today, we will show you in a step-by-step manner how to run Harmony Node from scratch. Just follow the steps – and you will be able to run a Harmony node on your own.

What is Harmony Node?

Harmony is a blockchain platform for providing scalable & secure infrastructure for decentralized applications (dApps) and transactions. It utilizes a sharding technique to achieve high throughput & low latency – making it suitable for a wide range of applications from finance to gaming.

System Requirements to Run a Harmony Node

Before diving into setting up your Harmony node, ensure you have the following:


  • A dedicated machine or virtual private server (VPS) with at least 4 cores, 8 GB RAM, and sufficient storage space of at least 100 GB SSD is recommended.
  • Stable internet connection with adequate bandwidth to handle network traffic.


  • An operating system supported by Harmony (Linux distributions like Ubuntu 18.04 LTS or higher are commonly used).
  • Basic command-line proficiency.

Harmony Wallet

Create a Harmony wallet if you don’t already have one. This wallet will store any earned rewards and interact with the Harmony network.

How to Run Harmony Node? | A Step-by-Step Approach

Step 1: Installing Dependencies

You must ensure your server or machine has the necessary software dependencies installed – for running a Harmony node.

Install Docker

Harmony nodes are typically deployed using Docker containers for easy management & deployment. Install Docker by following the instructions specific to your operating system from the official Docker documentation.

Install Docker Compose (Optional)

Docker Compose simplifies the management of multi-container Docker applications. Install Docker Compose after installing Docker itself.

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli

Step 2: Setting Up Your Node

Once Docker & Docker Compose (if used) are installed, proceed to set up your Harmony node:

Clone the Harmony Repository

git clone
cd harmony


  • Navigate to the scripts directory within the cloned Harmony repository.
  • Edit the node_config.toml file to configure your node settings, such as validator information, network settings, and logging preferences.

Generate Keys

Generate the necessary keys for your Harmony node. These keys will be used to identify your node on the network and for signing blocks.

./ -B -k <validator_name> -p <validator_password>

Replace <validator_name> and <validator_password> with your chosen values. Keep these secure – they are crucial for node operation.

Start the Node

Run the following command to start your Harmony node:

./ -N <node_type>

Replace <node_type> with validator when setting up a validator node. For non-validator nodes, use explorer, partner, or all.

Monitor Node Status

Check the status of your node and ensure it is synchronized with the Harmony blockchain:

./ -W

Step 3: Joining the Network

After setting up your Harmony node, you must join the Harmony network:

Obtain Tokens for Staking

Acquire ONE tokens to stake. Staking tokens are required to participate as a validator or a delegator on the Harmony network.

Stake Your Tokens

Use your Harmony wallet to stake tokens to your validator address. This process varies depending on your wallet interface. Although it typically involves selecting your validator node and specifying the amount to stake.

Monitor Validator Performance

Regularly monitor your validator’s performance, including block signing success rate and network uptime. Use tools provided by Harmony or third-party monitoring services for detailed analytics.

Step 4: Maintaining Your Node

Running a Harmony node is an ongoing commitment. You must make sure that your node remains updated with the latest software releases and security patches:

Update Node Software

Periodically check for updates to the Harmony software and update your node accordingly. This is to ensure compatibility with the latest network protocols & features.

Backup Keys

Regularly back up your validator keys and store them securely. These keys are critical for maintaining node operation and accessing rewards.

Monitor Network Health

Stay informed about network upgrades, maintenance schedules, and community announcements for your node’s compatibility with network standards.


When you run a node, it is an experience of learning that can reward you, too, if done right. You also contribute to the entire blockchain & DeFi ecosystem – a good deed. Follow this guide to run a Harmony node from scratch. Remember to stay engaged with the Harmony community for support & updates and to keep your node’s performance at peak.

Here’s a quick revision on how to run a Harmony node: install necessary dependencies, configure the node, join the network, and maintain it for optimal performance. This guide provides a comprehensive walkthrough for anyone looking to participate in the Harmony blockchain ecosystem.

Q1. How do I earn rewards by running a Harmony node?

Ans. Running a Harmony node allows you to earn rewards through staking. By staking ONE tokens as a validator or a delegator, you contribute to the network’s security and earn a share of block rewards and transaction fees.

Q2. What are the hardware requirements for running a Harmony node?

Ans. To run a Harmony node, you must have a machine or VPS with at least 4 cores, 8 GB RAM, and 100 GB SSD storage. This setup ensures your node can handle the computational and storage demands of participating in the network.

Q3. How do I monitor the performance of my Harmony node?

Ans. You can monitor your Harmony node’s performance using tools provided by Harmony or third-party services. Check metrics, block signing success rate, uptime, and network synchronization to ensure your node is working fine.

Q4. How often do I need to update my Harmony node software?

Ans. Regularly update your Harmony node software to stay compatible with the latest network upgrades and security patches. Check for updates from Harmony’s official channels and follow their guidelines for timely updates.

Q5. Can I run multiple Harmony nodes on the same machine?

Ans. Yes! You can run multiple Harmony nodes on the same machine using Docker containers. Each node should have its own set of keys and configurations to operate independently and contribute to the network.

Q6. What if I need human help with running a node?
