Mau nanya nih om-om senior baru kali ini nyoba sign message,
Tadi udah nyoba buat sign pake Electrum, ini hasilnya:

-----BEGIN BITCOIN SIGNED MESSAGE-----
Date: June 09, 2018 URL: https://bitcointalk.org/index.php?action=profile;u=1022328 Hello, this is yusuf98. My bitcoin address is bc1q6ny4np75kl9dwtn66scyr4vljx7d2lhjwdwzmt
-----BEGIN SIGNATURE-----

-----END BITCOIN SIGNED MESSAGE-----

Kalok Verify di electrum keluar pesan Signature Verified, tapi pas nyoba verify di brainwalletx, malah muncul pesannya kek gini:
Message failed to verify!

Itu gimana ya, apa memang masing-masing punya aturan sendiri buat verify nya?
