Set up an always-on Holochain node

An EdgeNode is a dedicated peer that stays online so your group doesn’t have to.

In a peer-to-peer application, two people need to be online at the same time for data to sync — if one person adds something and goes offline before anyone else appears, the group falls out of sync. An always-on node solves that: it holds a copy of the group’s data and is there whenever anyone else comes back.

This guide takes you from a spare machine to a running node joined to a Moss group.

What you’ll need

  • A dedicated machine — a HoloPort, an old laptop, or any spare computer you can leave running on a wired connection
  • A Linux install that runs OCI containers
  • Keyboard, monitor, HDMI cable
  • Moss installed on your everyday computer

What the guide covers

  1. Install Moss, create a group, and copy the invite link
  2. Prepare the dedicated machine
  3. Pull and launch the EdgeNode container
  4. Join your Moss group with the wdocker CLI — after which the node checks for new tools hourly and installs them itself

The appendix covers manual installation without wdocker, installing hApps from .webhapp files, and setting up SSH access via GitHub keys.

Once it’s running, the node is a stable backbone for every tool your Moss group uses — project boards, notes, chat, spreadsheets and files — held by a peer that stays online whether or not anyone else is.
