Package chaincfg defines chain configuration parameters for the three standard Decred networks and provides the ability for callers to define their own custom Decred networks.

Although this package was primarily written for dcrd, it has intentionally been designed so it can be used as a standalone package for any projects needing to use parameters for the standard Decred networks or for projects needing to define their own network.

Sample Use

package main

import (
	"flag"
	"fmt"
	"log"

	"github.com/decred/dcrutil"
	"github.com/decred/dcrd/chaincfg"
)

var testnet = flag.Bool("testnet", false, "operate on the testnet Decred network")

// By default (without -testnet), use mainnet.
var chainParams = &chaincfg.MainNetParams

func main() {
	flag.Parse()

	// Modify active network parameters if operating on testnet.
	if *testnet {
		chainParams = &chaincfg.TestNetParams
	}

	// later...

	// Create and print new payment address, specific to the active network.
	pubKeyHash := make([]byte, 20)
	addr, err := btcutil.NewAddressPubKeyHash(pubKeyHash, chainParams)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(addr)
}
