Geth, Parity, and Ganache are three of the most common Ethereum clients you will encounter as you build decentralized applications. You've already briefly seen how Ganache works by using ganache-cli in the second chapter. And, to be honest, you've seen most if it already! This chapter will touch on the last few bits of Ganache, and it will take a shallow dive into Geth and Parity to give you an idea of the power of the most widely used Ethereum clients.
Although we will briefly cover Geth and Parity, we will mainly focus on Ganache for the rest of this book as it allows you to get a Truffle Dapp up and running quickly, and with the least development pain.
