Note: This won’t handle encryption. We’re working on that but key management is a rather hard problem so it will take time. If you’d like an example project, take a look at peer pad: https://peerpad.net/
I believe as time passes more and more dapps will appear and all these issues would be solved, just like you have online tools in the traditional client-server internet that didn’t exist years ago.
This is a brand new world, like colonists just arrived to a new untamed land, we gotta build things up!!
(altho, as they said, there are already some cute things made already)
