📌 This guide will help you to install a NKN node using Linux.


NKN Node tech requirement
Spec Requirement
Operating system Ubuntu is recommended (works perfectly with Debian)
Memory 1GB
Hard Drive Disk 30GB (SSD is recommended)

A 25GB configuration is possible but it is recomanded to restart every noon the node in order to keep the chain size as light as possible

CPU Most of them works (AMD, ARM, MIPS,...)
Internet connection speed 10Mbps up and down is a minimum
Internet usage The amount of data used per month can be as high as multiple TB per month
IP address 1 IP version 4 (IPv4) is require per node. There is no way (and it would make no sense) to run multiple node on a single IP. IPv6 is not available.
Port forwarding You need to be able to reach the TCP/UDP ports 30001-30021. Optionally the TCP ports 30022-65535 for NKN Commercial services like nConnect. See our page about port forwarding

Before you start

Please be sure to check all the following points

  • [ ]  I have 10.1NKN mainnet tokens (or I'm ready to buy them)
  • [ ]  My server is connected to internet
  • [ ]  I have setup my port forwarding

It's now time to ask yourself an important question: are you confident with the concepts of console, SSH, bash ?


Here is a cheatsheet of commands helping you to debug and understand better your node.

Find and reach your node install directory

cd "$(find / -type d -name "nkn-node" 2>/dev/null)"

Verify your node service status

systemctl status nkn-commercial.service

Check on your node last logs

journalctl -u nkn-commercial.service

The following commands needs to be entered inside your node install directory

Display your node status information

./nknc info -s

Display your node log in real time

tail -f nkn-node.log


Switch to root user if not root yet

sudo su -

Run the following command

/home/nkn/nkn-commercial/nkn-commercial uninstall
