Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.

If you can do a P2P transaction like that, you need either a central server or a blockchain or equivalent to prevent double-spends. There is no other way. Satoshi's innovation for Bitcoin was developing a system (blockchain) that can do this without a central server.
I don't know how the technical implementation will work, but here is a post I found.
The idea is that you transfer money from the bank to your device, just like withdrawing cash from an ATM. Transferring money from one wallet to another should be able to be offline.
It seems like privacy is a priority, if only to satisfy privacy groups and improve acceptance.
You still need to be able to defend against double spends, meaning I digitally copy my wallet and give two people the same 5€.
