Introduction

This section addresses common questions about setting up and running a Nesa node.

---

What is a Nesa node?

A Nesa node is a server that participates in the Nesa blockchain network, either by validating transactions (Validator) or by handling inference tasks for AI models (Miner).

What are the hardware requirements for running a Nesa node?

• CPU: Multi-core processor

• Memory: 4 GB RAM minimum

• Storage: 50 GB free disk space (or more depending on the size of the model(s) you plan to power)

How do I view my node's performance?

Visit https://node.nesa.ai and enter your Node ID.

You can find your Node ID by re-running the bootstrap script and reading it from the script's header.

How do I install Docker?

• Linux:

  # Add Docker's official GPG key:
  sudo apt-get update
  sudo apt-get install ca-certificates curl
  sudo install -m 0755 -d /etc/apt/keyrings
  sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
  sudo chmod a+r /etc/apt/keyrings/docker.asc
    
  # Add the repository to APT sources:
  echo \
    "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
    $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
    sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
  sudo apt-get update
  sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
  # Example command to install Docker on macOS using Homebrew
  brew install --cask docker
  # Example command to install Docker on Windows using PowerShell
  choco install docker-desktop

• macOS:

  brew install --cask docker

• Windows (WSL):

  choco install docker-desktop

How do I configure my node as a Validator or Miner?

During the bootstrap script execution, you will be prompted to select a node type:

• Validator: Enter the private key for the validator.

• Miner: Choose between Distributed Miner or Non-Distributed Miner, and select or enter a model.

What should I do if the bootstrap script fails to run?

• Verify network connectivity

• Check curl installation

• Run the script with appropriate permissions

# For all operating systems
curl -L https://raw.githubusercontent.com/nesaorg/bootstrap/master/bootstrap.sh | bash

How do I check if my node is running correctly?

Verify Docker containers status:

docker ps

Ensure all required Docker containers are running.

What are swarms, and how do I join or start one?

A swarm is an orchestrator and miner(s) working collaboratively to handle inference tasks. During the bootstrap script execution, you may:

• Join an existing swarm: Select from a list of available swarms.

• Start a new swarm: Enter the model name to run.

Advanced: Can I override my node's model cache directory?

Yes, set your preferred cache directory using the HF_HOME variable in ~/.nesa/env/orchestrator.env.
