Implementation of Ethereum nodes and clients is available in multiple languages, including Go, C++, Python, JavaScript, Java, and Ruby. The functionality or usability of these clients is the same across languages, and developers should choose the language implementation they are most comfortable with. This book uses the Go implementation known as Geth, which acts as an Ethereum client to connect to public and test networks. It is also used to create the mining and EVM (transaction nodes) for private networks. Geth is a command-line tool written in Go for creating a node and miners on a private chain.
