Cjdns is an asymmetrically-encrypted IPv6 Virtual Private Network IPv6 using decentralized mesh networking. The network is multiplatform, with clients and servers offered for OpenWRT, FreeBSD, Linux, NetBSD, MacOS, and Windows^[1] based on free software using the GPL V3. Unlike TOR, i2p or FreeNet, total anonymization is not the priority.^[2] The goal is to build a trusted, resilient network.^[3] This software was originally developed by computer researcher Caleb James DeLisle.^[4] His initials represent the first three letters of the network's name.

Characteristics

The data is encrypted from end to end, so the relays do not need to be trusted.^[5]

packets are routed based on their source, thus making it possible to experiment with network routing algorithms without risk of dropping connections (aided by anti-spoofing).^[5]

Peer connections can be configured as UDP tunnels, or auto-configuration on Layer 2 ethernet via the fc00: IPv6 address space.^[5]

Network deployments

Seattle's Meshnet network using Hyperboria runs on cjdns, as well as the Guifi.net network. 21,000 Wi-Fi terminals in Catalonia are based on Cjdns.^[4]

A similar network called Santa Cruz Meshnet, is deployed in Santa Cruz.^[1]

Similar projects are being carried out in Toronto, Virginia (USA), Germany, France, New York City (NYC Mesh and San Diego.^[6]

Higher-layer applications

Most applications that are compatible with the TCP/IP Internet protocol will work on a Cjdns network, such as video conferencing, for example with Linphone. Other applications specifically developed for Cjdns exist, such as Cjdradio.^[7]
