It happens in the movies all the time. The good guys and the bad guys do it. But it doesn’t seem at all realistic. Even in one company it’s expensive to ensure you purge all the info your required to. So many systems. On the flip side. If everyone knows your exact identity, there is no privacy or anonymity. This kind of seems opposite the model of simplex chat. Syncronized, Tokenized or local identity? They are somewhat in conflict - no?
