Function hotshot_types::data::null_block::memoized_original_commitment

pub fn memoized_original_commitment(
    num_storage_nodes: usize,
) -> Option<VidCommitment>

The commitment for a null block payload.

Note: the commitment depends on the network (via num_storage_nodes), and may change (albeit rarely) during execution.

We memoize the result to avoid having to recalculate it.
