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 anonymity 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
editThe 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]
