Prerequisites

Before running the script to set up your Nesa node, ensure you have the following ready

Note: This software is in beta and primarily targets Ubuntu/Debian machines with CUDA-enabled GPUs. Support for other hardware/software configurations is experimental and will improve over time.

Introduction

Before running a Nesa node, ensure your system meets the following prerequisites. This will help you set up and run the node smoothly.

---

System Requirements

Hardware Recommendations

• 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'd like to power)

• Network: Stable internet connection

Note: Miner nodes operate optimally with high-performance graphics hardware.

Supported Operating Systems

• Linux (Ubuntu, Debian, CentOS, etc.)

• macOS

• Windows (with WSL recommended)

Software Requirements

Required Software

• GPU Drivers: Required for hardware acceleration. Please consult your GPU manufacturer's website for reference.

• Nvidia Toolkit: Applicable to machines with an NVIDIA graphics card. Install Toolkit
• Docker: Required to run the node. Install Docker

  # Example command to install Docker on Debian/Ubuntu
    # 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

• curl: Required to fetch the bootstrap script. Install curl

  # Example command to install curl on Ubuntu
  sudo apt-get update
  sudo apt-get install -y curl

  # Example command to install curl on macOS using Homebrew
  brew install curl

  # Example command to install curl on Windows using PowerShell
  choco install curl

Installing Necessary Dependencies

• gum: The script installs gum if not present.

• jq: The script installs jq if not present.

  # Command to check if jq is installed
  jq --version
  
  # If jq is not installed, the script will attempt to install it

Account and Token Requirements

Hugging Face API Token

You will need a Hugging Face API token. Get your token here.

Hint: Make sure to save your Hugging Face API token securely. You will need it during setup.

Moniker for Your Node

Decide on a unique name (moniker) for your node.

Hint: Choose a moniker that reflects the identity of your node within the network.

Node Type Selection

Decide whether your node will be a Validator or a Miner. Validators participate in consensus, while Miners handle inference tasks.

Validator

• Role: Validators are responsible for verifying transactions, creating new blocks, and maintaining the security and integrity of the blockchain.

• Tasks: Participate in the consensus process, validate transactions and blocks, and earn rewards for their services.

• Requirements: Require a stable internet connection and typically less less computational power than miner nodes. In a PoS network, they also stake tokens as collateral.

Miner

• Role: Miners execute the heavy-lifting components of AI inference.

• Tasks: Collect and verify transactions, bundle them into blocks, and earn rewards for successfully adding blocks to the blockchain.

• Types:

  • Distributed Miner: Joins existing swarms for collaborative mining.

  • Non-Distributed Miner: Operates independently without collaboration.

• Requirements: Vary depending on whether they are distributed or non-distributed. Both types require good computational power and internet stability.

Administrative Rights

Ensure you have administrative rights on your system.

Linux/macOS

You should have the ability to use sudo for installing packages and running Docker.

For linux-based systems, ensure your user is part of the docker group by running the following commands:

# Create a docker group (if non-existent), adds the current user, 
# and applies group membership immediately in the current session
sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

Hint: To check if you have sudo privileges, run the following command:

sudo -v

Windows

You should have an administrator account or use WSL with administrative privileges.

Hint: On Windows, you can check if you are an administrator by going to Control Panel > User Accounts > Manage User Accounts.
