Nexus Node

Guide to help you run an Erebrus Nexus Node that enables AI Agents & Applications Hosting over dVPN

Nexus Node Overview

The Nexus Node is a high-performance node designed for AI workloads, application orchestration, and decentralized VPN. Unlike the Beacon Node, which primarily functions as a VPN relay, Nexus Nodes provide AI Agent hosting, firewall deployment, and global DNS assignment for applications deployed by users.

Running a Nexus Node allows you to earn rewards for sharing compute and storage resources, supporting decentralized AI coordination and censorship-resistant applications. Operators must have a static IP and a wildcard domain to enable seamless deployment and connectivity. While a home lab setup is possible, cloud deployment is recommended for performance and reliability.

By hosting a Nexus Node, you help build a resilient AI coordination layer, enabling users to deploy AI agents, self-hosted apps like Nextcloud, and privacy-enhancing tools.

Prerequisites

Hardware Requirements

• Operating System: Linux

• Minimum Hardware Requirements:

  • 8GB RAM (Recommended: 16GB+)

  • 4 vCPUs (Recommended: 8 vCPUs)

  • 200GB+ SSD storage (Recommended: 500GB+ for AI Agents hosting)

  • Static IP required

  • Domain and Wildcard domain (for App Orchestration & DDNS Assignment)

Network Requirements

• Incoming traffic allowed on ports:

  • 51820 (WireGuard VPN)

  • 9002 (LibP2P peer discovery)

  • 443 & 80 (Web applications & API access)

• A stable, high-bandwidth internet connection (preferably wired)

• Basic familiarity with command-line interface (CLI) i.e. terminal

• Node Wallet (i.e. valid mnemonic on the supported chain) for on-chain registration and checkpoint

Estimated Cloud Deployment Costs (Per Month)

Nexus Nodes require higher computing power, making cloud deployment preferable. Here’s an estimated monthly cost based on recommended specifications:

Cloud Provider	Instance Type	CPU	RAM	Storage	Static IP	Estimated Cost
Hetzner	AX41	8 vCPUs	16GB	512GB SSD	✅ Included	~$50/month
AWS EC2	t3.xlarge	4 vCPUs	16GB	500GB SSD	✅ $5 extra	~$90/month
DigitalOcean	General Droplet	8 vCPUs	16GB	500GB SSD	✅ $5 extra	~$80/month
Vultr	High-Performance	8 vCPUs	16GB	500GB SSD	✅ Included	~$60/month

License & Staking Requirements

• License Fee: A Node License NFT is required to run a Nexus Node.

• Staking Requirement: 150 USD (Currently $0 USD)

  • Ensures great user experience while improving stability and preventing spam deployments.

  • Higher staking incentivizes reliable operators.

  • Staking requirement changes based on demand & supply.

• Revenue Model: Earn rewards for both:

  • Enabling encrypted, censorship-resistant VPN

  • Hosting AI Agents & decentralized apps

Installation

1. Install the Node Software

Run the following command in your terminal:

sudo bash <(curl -s https://raw.githubusercontent.com/NetSepio/erebrus/nexus_installer/install-node.sh)

Follow the on-screen instructions to install dependencies.

2. Configure the Node

• Set up public IP and wildcard domain.

• Choose resource allocation for AI compute & app hosting.

• Configure firewall settings for security.

3. Verify Configuration

• Ensure all necessary ports are open.

• Test AI workload execution & VPN reachability.

Once the configuration is verified, the Nexus Node will become active and start processing hosting tasks & handle VPN client connections.

Maintenance & Monitoring

• Update your node software regularly for performance & security patches.

• Monitor system usage (CPU, RAM, storage) to ensure smooth operation.

• Use logging tools to track AI task execution & app deployments.

Troubleshooting

1. AI Agents Not Running or Get Stopped Frequently

   Issue: AI Agents fail to run properly. Solution: Ensure enough RAM & storage is allocated and dependencies (Caddy, Docker, Git) are installed and configured correctly.

2. Wildcard Domain Not Resolving

   Issue: Apps hosted on the node are inaccessible. Solution: Check your DNS settings and verify that the wildcard domain points to your static IP.

3. Firewall Blocking Traffic

   Issue: Users can't connect to your node. Solution: Ensure the required ports are open in your firewall settings.
