Peer-to-peer backup is not a new idea, but it is a difficult challenge. This is where the research effort comes into play. [S]afer implements a new peer-to-peer based protocol based on the latest and most advanced research techniques and innovative ideas, such as block-chains, IPv6 "NAT friendly" overlay network protocols, and many more.
Because most of this research is still ongoing, we cannot tell much yet about it until our first beta release is out. At this point we will proudly publish a whit paper to describe in details the [S]afer protocol internals.
Eventually, it is our plan to fully release the [S]afer box software as OpenSource once the service is in commercial production.
