Function serai_coordinator::substrate::verify_published_batches

pub(crate) async fn verify_published_batches<D: Db>(
    txn: &mut D::Transaction<'_>,
    network: ExternalNetworkId,
    optimistic_up_to: u32,
) -> Option<u32>

Verifies Batchs which have already been indexed from Substrate.

Spins if a distinct Batch is detected on-chain.

This has a slight malleability in that doesn’t verify who published a Batch is as expected. This is deemed fine.
