Setting up the environment

We are going to run the Ethereum client Geth to create a private blockchain with only one user: ourselves. Let's get started:

1. First, open up a Terminal window and navigate to any directory that you want. From there, we are going to create the hello_world directory to host the data of the two blocks, as follows:

    $ mkdir hello_world

2. We will also create a subdirectory under hello_world to host all the logs. First, navigate to the directory we just created, that is, hello_world. Next, a directory named logs , as follows:

    $ cd hello_world
    $ mkdir logs

With the directories created, we have set up the environment to configure the genesis file. Let's move on to the next step.
