Geth (Go Ethereum) is the official Ethereum client implementation written in the Go programming language. It enables users to run a full Ethereum node, interact with the Ethereum network, deploy smart contracts, and mine Ether. Geth is widely used by developers, enterprises, and blockchain enthusiasts for building and maintaining decentralized applications (dApps).

Features of Geth:

• Run full or light Ethereum nodes on public or private networks.
• Interact with smart contracts using JSON-RPC, IPC, or WebSocket interfaces.
• Built-in support for mining and transaction signing.
• Extensible via JavaScript console and powerful APIs.
• Supports synchronization, peer discovery, and custom chain configurations.
