---

Returns the mining nodes (i.e., the members of the DS committee and shards) at
the specified DS block.

**Notes:**

1. Nodes owned by Zilliqa Research are omitted.
1. `dscommittee` has no `size` field since the DS committee size is fixed for a
   given chain.
1. For the Zilliqa mainnet, this API is only available from DS block 5500
   onwards.
