Celestia Node
Golang implementation of Celestia's data availability node types (light | full | bridge).
The celestia-node types described above comprise the celestia data availability (DA) network.
The DA network wraps the celestia-core consensus network by listening for blocks from the consensus network and making them digestible for data availability sampling (DAS).
Continue reading here if you want to learn more about DAS and how it enables secure and scalable access to Celestia chain data.

Minimum requirements
| Requirement | Notes |
|---|---|
| Go version | 1.21 or higher |
System Requirements
See the official docs page for system requirements per node type:
Installation
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node
make build
sudo make install
For more information on setting up a node and the hardware requirements needed, go visit our docs at https://docs.celestia.org.
API docs
The celestia-node public API is documented here.
Node types
- Bridge nodes - relay blocks from the celestia consensus network to the celestia data availability (DA) network
- Full nodes - fully reconstruct and store blocks by sampling the DA network for shares
- Light nodes - verify the availability of block data by sampling the DA network for shares
More information can be found here.
Run a node
<node_type> can be: bridge, full or light.
celestia <node_type> init
celestia <node_type> start
Please refer to this guide for more information on running a node.
Environment variables
| Variable | Explanation | Default value | Required |
|---|---|---|---|
CELESTIA_BOOTSTRAPPER |
Start the node in bootstrapper mode | false |
Optional |
