  description: |
    JSON-RPC methods in the `da` module of celestia-node. Implements the modular
    Data Availability interface (https://github.com/rollkit/go-da) so that rollups
    and other execution layers can post blobs to and retrieve them from Celestia
    without coupling to celestia-node internals.
