GM world rollup: Part 3 ​

This tutorial is part 3 of the GM world rollup tutorials. In this tutorial, it is expected that you've completed part 1 or part 2 of the tutorial and are familiar with running a local rollup devnet or posting to a Celestia testnet.

Deploying to Celestia Mainnet Beta ​

🪶 Run a Celestia light node ​

Fully sync and fund a light node on Mainnet beta (celestia). Follow instructions to install and start your Celestia data availability layer light node selecting the Arabica network. You can find instructions to install and run the node. After the node is synced, stop the light node.

Clear previous chain history ​

Before starting the rollup, we need to remove the old project folders:

rm -r $HOME/go/bin/gmd && rm -rf $HOME/.gm

Start the rollup on mainnet ​

For this portion, you will need to stop the rollup that you have running from parts 1 and 2 of the tutorial, using Control + C in the terminal.

1. Download the script for deploying to Celestia's Mainnet Beta:

   bash

   # From inside the `gm` directory
   wget https://raw.githubusercontent.com/rollkit/docs/main/scripts/gm/init-mainnet.sh

2. Ensure that the account for your light node is funded.

3. Run the init-mainnet.sh script:

   bash

   bash init-mainnet.sh

4. Watch as your rollup posts blocks to Celestia!

5. View your rollup by finding your namespace or account Celenium.

View the example rollup's namespace on Celenium.

openssl rand -hex 10

Restarting your rollup ​

When you ran init-mainnet.sh, the script generated a script called restart-mainnet.sh in the $HOME/gm directory for you to use to restart your rollup.

In order to do so, restart celestia light node and then run:

bash restart-mainnet.sh

Next steps ​

Congratulations! You have a Rollkit rollup running on Celestia's Mainnet Beta.
