Hemi Network

Prerequisites

  • Operating System: Linux (Ubuntu 20.04/22.04 recommended)

  • Hardware Requirements:

    • CPU: 4+ cores

    • RAM: 16GB+

    • Storage: 500GB SSD+

    • Network: High-speed, stable internet connection with a static IP

  • Software Requirements:

    • Docker and Docker Compose

    • Git

    • Curl or Wget

Step 1: Update and Install Dependencies

Update your system and install necessary dependencies.

sudo apt update && sudo apt upgrade -y
sudo apt install -y curl git jq build-essential

Step 2: Install Docker

Install Docker and Docker Compose.

# Install Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

# Install Docker Compose
sudo apt install -y docker-compose

Verify Docker installation:

docker --version
docker-compose --version

Step 3: Clone Hemi Network Repository

Clone the official Hemi Network GitHub repository.

git clone https://github.com/HemiNetwork/hemi-core.git
cd hemi-core

Step 4: Configure Node

Generate the node configuration file.

cp config/default-config.yml config/config.yml
nano config/config.yml

Edit the config.yml file to include your desired settings, such as:

  • Node Name: Choose a unique name for your validator.

  • Network Configuration: Ensure the correct network (testnet/mainnet) is specified.

  • Validator Key: You will generate this in the next step.

Step 5: Generate Validator Keys

Run the following command to generate your validator keys:

docker run --rm hemi-node generate-keys

This command will output a public/private key pair. Save these keys securely.

Step 6: Start the Validator Node

Create a docker-compose.yml file to manage your node:

version: '3.8'
services:
  hemi-node:
    image: hemi-network/hemi-node:latest
    container_name: hemi-validator
    ports:
      - "30303:30303"  # Replace with the required ports
    volumes:
      - ./data:/data
    environment:
      - NODE_NAME=<Your Node Name>
      - VALIDATOR_KEY=<Path to Your Validator Key>
    restart: always

Start the validator node:

docker-compose up -d

Step 7: Verify Node Status

Check the logs to ensure your node is running correctly.

docker logs -f hemi-validator

Step 8: Stake Tokens

To become a validator, you need to stake the required amount of tokens. Follow the official staking documentation on Hemi Network or use their staking portal to delegate your tokens.

Step 9: Monitor and Maintain Your Node

Set up monitoring tools like Prometheus and Grafana to ensure your node remains healthy and performs well. Additionally, automate backups of your node's data and keys.

Useful Commands

  • Restart Node:

    docker-compose restart

  • Stop Node:

    docker-compose down

  • Check Node Logs:

    docker logs -f hemi-validator
