What is Geth?
Geth is the most popular implementation of Ethereum. It’s the software necessary to run an Ethereum node (i.e., client), and it’s written in the Go programming language.
On Ethereum, individual computer connections, known as nodes, manage and store copies of the Ethereum blockchain. Often referred to as a decentralized computer, Ethereum uses implementations like Geth as its operating system, following this analogy.

Geth allows users to interact with the Ethereum network by interacting with smart contracts, querying blockchain data, or sending transactions.
The Go Ethereum implementation has been around since the dawn of the network. It has stood the test of time as one of the most reliable and easy to develop with Ethereum implementations. It features a suite of developer tools and APIs that help streamline and simplify the creation of decentralized applications.
Geth is completely open source and is home to a bustling developer community.
Who is Geth For?

Geth is for everyone interested in programmatically interacting with the Ethereum network via a time-tested and robust interface.
Go-ethereum, also known as Geth for short, is the most popular Ethereum client and because it’s in Go, it provides everything we’ll ever need for reading and writing to the blockchain when developing applications using Golang.

Decentralized application developers can use Geth to run functions directly from the command line and develop and debug their products. Independent node operators who wish to have complete control and autonomy over their connection to the Ethereum network can also use Geth.
Conclusion
Geth is one of the most reliable and battle-hardened Ethereum clients. Developers and node operators use it to connect to and interact with the Ethereum network.
