 The "OFF System" is a kind of anonymous, fully decentralized P2P file sharing program and network.In contrast to other anonymous file sharing networks, which derive their anonymity from forwarding their data blocks via intermediate network nodes, "OFF" derives its anonymity from anonymizing the data files.Thus, the system refers to itself as a "brightnet" to contrast its method of operation with that of private file sharing systems known as darknets and with traditional, forwarding anonymous P2P programs.
