Quick start guide
In this section, we show you how to get started with installing the needed libraries and packages in Celestia to help you run a node on Celestia.
Install celestia-node allows you to get started with running a light node and do data availability sampling.
Light nodes are the best nodes to test out initially if you are new to participating in Celestia.
celestia-node client also allows you to run other types of data availability (DA) nodes like bridge and full DA storage nodes, which will be covered in later sections.
Install celestia-app allows you to get started running a consensus node.
celestia-app is the software that allows you to run validator nodes and also provide RPC endpoints.
celestia-app covers the consensus layer, while celestia-node covers the DA layer.
If you are planning to run a light node, it is recommended to use Arabica, which you will find options to connecting to in the later sections.
If you plan on running a validator, your only option is to run your node on Mocha.
In this quick start guide, we will go over installing both of the software clients: celestia-node and celestia-app.
If you just want to run a light node, you don't need to install celestia-app and can skip that part.
Proceed to the next section in order to get started.
