Cjdns is an encrypted (asymmetric cryptography) IPv6 VPN using a mesh network. It is decentralized and multiplatform (FreeBSD, Linux, NetBSD, MacOS, Windows^[1]), based on free software under the GPLv3 license. Unlike other VPN networks like TOR, I2P or Hyphanet, complete anonymization is not a priority.^[2] The goal is rather to create a network of trust.^[3]

This software is originally developed by computer scientist, Caleb James DeLisle.^[4] Their initials are the first three letters of the network service name.

Characteristics[edit]

Packets are end to end encrypted, meaning relays don't need to be trusted.^[5]
Packets are source routed, allowing seamless upgrades of, and experimentation with routing algorithms without risking an outage.^[5]
The data for routing comes from a distributed hash table listing the peers of each node, which prevents spoofing.^[5]
Peers can be configured explicitly as UDP tunnels, or automatically configured on ethernet via layer 2 protocol 0xfc00.^[5]

Deployed networks[edit]

The Seattle Meshnet network using Hyperboria, as well as the Guifi.net network, providing 21000 Wi-Fi access points in Catalonia, are based on Cjdns.^[4]

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

Other comparable projects are being carried out in Toronto, Virginia (United States), Germany, France, New York City and San Diego.^[6]
