I hope that in the near future such technologies will begin to be introduced everywhere and decontaminated networks will be introduced into our everyday life more actively.
Why do you think that this is necessary? why do we constantly try to introduce something that is not fully understood and understood. These technologies are good only in theory, no one can guess what will happen in practice.
And what is there to suppose. Such systems are transparent, without bureaucratic difficulties. Any user can track the transaction and make sure that everything went honest, it's fine.
But suddenly such a method would be dangerous for personal data, what if a particular node of the system is susceptible to hacking and the entire network will fall? I'm afraid of this.
In fact, such crypto-projects provide security at a high level. And I'm not talking about implementing such projects at once, naturally the transition should be gradual, I just hope that it will finally start.
I agree that if you introduce such innovative technologies gradually, people will be able to control the safe operation of these systems and, in the event of problems, can make adjustments to the operation of such systems in time.
