According to MEET.ONE, in the morning, BM actively interacted with community members in the Voice Telegraph Group to talk about the topic of information dissemination: 1. If we can only deliver messages via Bluetooth, how many people will participate in the dissemination? I think people will be too lazy to spread and lose interest in it; 2. Later, some members replied: Are you referring to real contact like people? BM: Yes, there is a need for communication (information) and reception (information) in communication. Some people will be the makers of information, others are the recipients of information; 3. It is conceivable how information flows before the Internet appears and needs to be transmitted through libraries, documents and other media. Now, with phones, Bluetooth, and encryption (applications), we can propagate and replicate those authenticated messages.
