func main() {
    // Sign up and get your secret token at https://api-dashboard.stampery.com
	events := stampery.Login("user-secret")

	for event := range events {
		switch event.Type {
		case "ready":
			// In this case we are going to add a random number to the string
			// to generate a different hash each time.
			r := rand.New(rand.NewSource(time.Now().UnixNano()))
			digest := stampery.Hash("Hello blockchain!" + strconv.Itoa(r.Int()))
			// Stamp the hash
			stampery.Stamp(digest)

		case "proof":
			fmt.Println("\nProof")
			p := event.Data.(stampery.Proof)
			fmt.Println("Hash: ", p.Hash)
			fmt.Printf("Version: %v\nSiblings: %v\nRoot: %v\n", p.Version, p.Siblings, p.Root)
			fmt.Printf("Anchor:\n  Chain: %v\n  Tx: %v\n", p.Anchor.Chain, p.Anchor.Tx)

		case "error":
			log.Fatalf("%v\n", event.Data)
		}
