Base58check to decimal

Hey @golangworld, you can use a package such as https://github.com/tv42/base58 to encode and decode to and from base58. This was the first package I found on the https://golanglibs.com website, but I’m sure there are other ones available too.

Here’s an example for you:

package main

import (
	"fmt"
	"log"

	"github.com/tv42/base58"
)

func main() {
	// Address.
	addr := []byte("1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN")

	// Encode addr to a big.Int.
	bigInt, err := base58.DecodeToBig(addr)
	if err != nil {
		log.Fatalln(err)
	}
	// Print the big.Int value.
	fmt.Println(bigInt)

	// Decode the bigInt value back to an address value.
	decoded := base58.EncodeBig(nil, bigInt)

	// Print the decoded addr.
	fmt.Printf("%s", decoded)
}
