That is very interesting comment @akdx.

Will it not make my computer to visible to the world? Will it not steal my personal information or compromise my computer's security in any way?

In order to set up a NOIA node you have to open ports in your router, which will allow users to receive content cached on your device. Generally opening ports is controversial, so I decided to allow experts from NOIA to clarify this issue. That is the reply I got from them:

It is completely safe. We selected ports 8048 tcp and 8058 udp that are free to other functionality, like http connection

There is a team of experienced and reputable people behind NOIA. I think they take care of our safety properly.

If you are still a bit distrustful, if NOIA didn't take care of our safety it is still virtually impossible to get into the device with enabled firewall (Widows system has a built-in firewall).
