Building QaaS


Now let's start building a QaaS platform, this lets us deploy, create, and join networks with just a click of a button. As you are aware, starting a Quorum node requires a lot of manual steps, such as creating the genesis.json file, the static-nodes.json file, and enode. As we are aiming to automate all these steps, it would require us to write automation scripts to perform these steps. So instead of writing complicated automation scripts, we will use Quorum Network Manager (QNM), which allows users to create and manage Quorum networks easily without any manual steps. 

QNM is an open source wrapper for Quorum to make it easy to set up Quorum networks. When you are using QNM, you no longer have to worry about enode, wallets, the genesis file, the static-nodes.json file, and so on. You can find the official QNM repository at https://github.com/ConsenSys/QuorumNetworkManager. At the time of writing, the latest version of QNM is v0.7.5-beta
