Setting up Quorum with IBFT

In this section, we will set up a Quorum network with four nodes, demonstrating how an IBFT network can be set up and carry out private transactions in Quorum. These steps can be performed manually, or we can use a tool called Quorum Wizard to quickly and easily spin up a Quorum network.

For details on the manual setup, you can refer to the detailed Quorum setup instruction on Quorum's official website here: https://docs.goquorum.consensys.net/en/latest/Tutorials/Creating-A-Network-From-Scratch/.

Node.js can be installed from this address: https://nodejs.org/en/.
