Next, we need to initialize the IPFS nodes for our system. Since we are setting up two nodes, we'll repeat the necessary steps twice, once for Node 1 and once for Node 2. Node 1 will be owned by Bank A, and Node 2 by Bank B.

1. First, initialize Node 1, using the following command on the Terminal. Make sure you are in the IPFS executable path, which in my case is /usr/local/bin/ipfs.

The IPFS_PATH parameter points to the location of the local node folder for the IPFS Node 1. By default, it is available at /home/<user name>/.ipfs. 

2. Update this location to the IPFS_PATH parameter, by running the following command:

IPFS_PATH=~/.ipfs ./ipfs init

• A new peer ID will be generated. It will look something like this: QmQVvZEmvjhYgsyEC7NvMn8EWf131EcgTXFFJQYGSz4Y83. 
• Keep it safe. We'll need it later for bootstrapping the nodes.

3. Next, repeat the same for Node 2 by executing the next few commands on the Terminal window.

We first need to point the IPFS_PATH parameter to the location of the local node folder for the IPFS Node 2. I've set it to /home/<user name>/.ipfs2 for Node 2.

4. Run the following command on the terminal to initialize IPFS Node 2:

IPFS_PATH=~/.ipfs2 ./ipfs init

A new peer ID will be generated similar to before. Make sure you copy and store the peer ID for this node as well.

This will create two nodes and two-node configuration paths for IPFS in the same local machine.
