Kaspa Nodes

This guide walks you through the process of deploying, managing, and connecting to a Kaspa Node (Mainnet or Testnet) using FluxCloud. Whether you’re setting up a new node or maintaining an existing one, this page provides step-by-step instructions and key details for a seamless experience.

How To Install a Kaspa Node

Overview

Deploying a Kaspa Node on FluxCloud allows you to participate in the Kaspa network with full redundancy, automated failover, and blockchain-backed registration — all managed from an easy-to-use web interface.

Steps

  1. Access FluxCloud

  1. Find Kaspa Node

  • Open the Applications → Marketplace tab.

  • Search for Kaspa and select the KaspaNode for Mainnet, or KaspaTestnet for Testnet.

    • Choose 16GB or 24GB depending on your budget, and usage of the node.

  1. Choose Subscription

  • Select your preferred subscription duration (starting at $27.20 per month).

  • Agree to the Terms of Service, then click Start Launching Marketplace App.

  1. Sign Your App

  • When the registration message appears, click Next.

  • Sign it using your chosen login method.

  • If you signed in via email, use the Flux Single Sign-On button.

  1. Register Your App

  • Review the price summary and click the green Register button.

  • Wait for registration to propagate across the Flux Blockchain, then click Next once Done.

  1. Complete Payment

  • Choose your payment method:

    • Fiat: Stripe or PayPal

    • Crypto: FLUX coin (5% discount)

  • After confirmation, your deployment is recorded on the Flux Blockchain and distributed globally. This process typically takes 10–30 minutes, after which your node begins syncing automatically.

With built-in auto-failover, FluxCloud is redundant by design. Each Kaspa Node deployment spins up three independent nodes that automatically fail over if needed, ensuring uptime and stronger decentralization — all for just $27 a month.

How to Manage Your Kaspa Node

Once deployed, FluxCloud provides all the tools you need to monitor, update, and control your Kaspa Node instances directly from the management dashboard.

Access Your Kaspa Node Logs

How to Access

Applications → Management → Manage App → Local App Management → Logs

  • Open the Management tab under Applications.

  • Select your KaspaNode from My Active Apps and click Manage.

  • In Local App Management, open the Logs tab.

Backend Selector

At the top right, you’ll find a FluxNode IP selector, allowing you to choose which node instance you want to inspect or control. Use the reload button to refresh the list of currently active FluxNodes running your app.

Why This Is Useful

  • Troubleshoot issues or monitor node performance.

  • Review startup or sync status messages.

  • Confirm your node is running and connected properly.

Successful Kaspa Node Synced 100%

  • If your Kaspa node is 100% synced you should see logs similar to the example below.

Connect to Your Kaspa Node

You can connect to your Kaspa Node directly via its public IP and designated ports for peer-to-peer, gRPC, or WRPC access.

How to Find Node IPs:

Applications → Management → Manage App → Global App Management → Running Instances

  • Open the Management tab under Applications.

  • Select your KaspaNode app and click Manage.

  • Under Global App Management, go to the Running Instances tab to view your node IPs.

Port Usage:

Port
Function

15111

P2P

15110

gRPC

17110

WRPC-Borsh

18110

WRPC-JSON

For testnet connections, replace the middle digit with “2” (e.g., 15211 for P2P).

Example P2P connection:

78.46.37.110:15111

Test your Connection:

You can use the website https://nodes.kaspa.ws/ to verify whether your Kaspa Node is publicly reachable via its P2P port.

  1. Open nodes.kaspa.ws.

  2. Enter one of your FluxNode IP addresses and the P2P port (15111) in the input fields.

  3. Click the Lookup button to test connectivity.

  4. If your node is reachable, you’ll see a confirmation message such as:

    Success! 65.109.52.141:15111 is a Crescendo compatible public node

Note: It may take up to a couple of hours after deployment for your node to become publicly reachable.

Update or Renew Your Kaspa Node

How to Access

Applications → Management → Manage App → Global App Management → Update/Renew

  • Open the Management tab under Applications.
