 ### Parameters
 
-For each column -- use `data_column_sidecar_{subnet_id}` subnets, where each column index maps to the `subnet_id`. The sidecars can be computed with `get_data_column_sidecars(signed_block: SignedBeaconBlock, blobs: Sequence[Blob])` helper.

 To custody a particular column, a node joins the respective gossip subnet. Verifiable samples from their respective column are gossiped on the assigned subnet.
