Feature Request: Auto-build Internal Contacts List (hashed) from Existing Contact List
So just like Telegram, WhatsApp, Viber, etc auto build an internal contacts list from my existing contacts but make the contactID a hash of the mobile number(SIM). This way the network doesn't see my actual contact's mobile numbers(SIM). So if all my friends do the same our hashes should align and I know who is who, even though the network has no actual mobile numbers(SIM). Also I will need to enter my own mobile number(SIM) and have it hashed to create the unique contactID for my account. Of course the hash is never displayed since my contacts actual name can be retrieved by reversing the hash and then looking up their name by matching the mobile number from my existing contact list.
In this case there could be no sms verification of the mobile numbers(SIM) so anyone could spoof being someone else. To handle this each contact should default to Unverified status. Once the contact has proven to me that they are who I thought they were, then I can mark the contact as Verified.
Sorry about the poor description I know its fuzzy hopefully you get the point.
