# Participate in the Celestia networks

## Mainnet Beta

Celestia's [Mainnet Beta](/operate/networks/mainnet-beta) is the production network
for deploying Mainnet Beta rollups and applications. This marks the
culmination of years of development and community testing. While
the network is stable and continues to receive updates, it remains
experimental and users may experience occasional instability or
reduced performance.

## Testnets

Celestia currently has one public testnet that you can participate in:

### Mocha testnet

[Mocha testnet](/operate/networks/mocha-testnet) is a testnet focused on enabling validators
to test out their infrastructure by running nodes connected to the network. Developers
can also deploy sovereign rollups on Mocha. Breaking network upgrades are coordinated
with the validator community.
