    // First, put a steward DID and its keypair in the wallet. This doesn't write anything to the ledger,
    // but it gives us a key that we can use to sign a ledger transaction that we're going to submit later.
    // The DID and public verkey for this steward key are already in the ledger; they were part of the genesis
    // transactions we told the SDK to start with in the previous step. But we have to also put the DID, verkey,
    // and private signing key into our wallet, so we can use the signing key to submit an acceptably signed
    // transaction to the ledger, creating our *next* DID (which is truly new). This is why we use a hard-coded seed
    // when creating this DID--it guarantees that the same DID and key material are created that the genesis txns
    // expect.
