Getting started

This is the official Ethereum documentation for the Go implementation. This document will help you get started and will guide you in familiarising with the Go API.

Getting the package

Use go's package manager to fetch the go-ethereum package: 
go get github.com/ethereum/go-ethereum
Verify the installation with a simple ethereum.go example program: 
package main

import (
    "fmt"
    "github.com/ethereum/go-ethereum/eth"
)

func main() {
    fmt.Println("Hello ethereum:", eth.Version)
}
And verify the output: 
go run ethereum.go # Hello ethereum: 1.x.x

Setting up a node

package main

import (
    "gitub.com/ethereum/go-ethereum/eth"
)

func main() {
    // setup ethereum. the rest of the defaults will be picked for us
    // (port, host, ipc, etc). Second argument is the type of node; full/light
    err := eth.New(eth.Config{
        Name: "My ethereum node",
    }, eth.Light)
    if err != nil {
        logger.Fatalln(err)
    }

    // let eth handle shutdowns
    eth.WaitForShutdown()
}
