 Given a set of blocks to be submitted to DA by the block manager, the `SubmitBlocks` first encodes the blocks using protobuf (the encoded data are called blobs) and invokes the `Submit` method on the underlying DA implementation. On successful submission (`StatusSuccess`), the DA block height which included in the rollup blocks is returned.
