🖥️ Run a Corn Node

Corn is an Ethereum Layer 2 built using the Arbitrum Orbit stack. With AnyTrust for data availability and Conduit as the sequencer.

This guide will help you set up a node for both Corn Testnet and Maizenet. For detailed instructions, the generalized manual on how to run a full Arbitrum Orbit node can be found here.

In order to set up your node, ensure you have the following:

  • Hardware Requirements: Ensure your system meets the necessary performance and storage benchmarks.
  • Parent Chain Access: An RPC endpoint for the parent chain (such as Ethereum or Sepolia Testnet).
  • Orbit Chain Details: Obtain the chain-specific parameters (e.g., RPC endpoints, Chain ID).

Testnet Celestia Configuration​

warning

Corn Testnet has recently migrated to use Celestia for Data Availability. AnyTrust should continue to run in parallel to enable legacy data access.
