Hi, we have created an application in which cryptocurrency can be sent by phone number, even if the user is not registered in the application itself! What do you think, how much will this mutual settlement between users simplify?
This is much more convenient than the private key. But I don't think it will be secure enough for us to trust, the phone number can be stolen at any time and abused. Either way, it's a great idea, but I think it will be very difficult for you to apply it to the blockchain.
