Light node: overview & quickstart

Celestia light nodes perform data availability sampling (DAS) to verify that block data is available without downloading it all. They can also post and retrieve blobs (data) from the Celestia network.

Overview

Light nodes are the most common way to interact with Celestia networks.

light-node

Light nodes:

  1. Listen for ExtendedHeaders (block headers + DA metadata).
  2. Perform DAS on received headers.

Optional: run a light node in your browser

The easiest way to try a light node is with Lumina.rs in your browser.

Lumina.rs in browser

You can also run Lumina on the decentralized explorer, Celenium.

If you see header: syncing in progress, wait for the node to sync or use fast sync.
