queue managers only. After you have worked through the Getting started with Hyperledger Fabric tutorials, understood What's happening behind the scenes, and have launched your network by using one of the Hyperledger Fabric samples, you should have the following configuration file in your /blockchain/fabric-samples/basic-network folder.

To connect to your blockchain network, we must use the configuration details from this file when we are Create the configuration file for the IBM MQ Bridge to blockchain.
