Buzzer is built on the Qbit blockchain and works directly with the Qbit network. To interact with network you need Qbit key pair (public & secret keys). Public Qbit key - is the only identity in the Buzzer network. No e-mails, cell phone numbers or other personalized entities. Also public Qbit key - is your personal Qbit address used, for example, to receive QBIT coins (platform cryptocurrency). Private or secret Qbit key - this is your unique key, used for signing your transactions i.e. send buzz, make like or reply and send QBIT coins to the other buzzers on the Buzzer social network platform.
