Hi TimeTeller!
First of all, it's not just the server, but many distributed servers with blockchain nodes.
If we're talking about an intruder, then access to a server won't help him. Because all information stored there is encrypted. Moreover, such a server will be regarded as a hacked and will be eliminated from actual blockchain nodes.
But who has the access of the iTrue platform's server?
Of course, those data need to be stored somewhere.
Or I'm not understanding things here. Please enlighten us.
