Understanding Geth

Geth, also known as Go Ethereum, is the most popular Ethereum implementation that allows you to do a wide variety of tasks. We will go through how to do most of them in the following sections to help you understand how to execute each of the commands that are required for every task.

You can install Geth easily with the following commands on macOS:

brew update
brew install ethereum
brew upgrade ethereum

Alternatively, if you're using Windows or Linux, you can go to geth.ethereum.org/downloads/ and get an executable for your system. In either case, the geth command will be available in your Terminal or command line after installation.
