The Circle is a peer-to-peer distributed file system written mainly in Python. It is based on Chord, which is a member of the distributed hash table (DHT) algorithm for its network routing method.

It supports file sharing, instant messenging with buddy lists, the Internet relay chat model of sending a message to a channel, and a personalized, trust-based news service.

• finding and sending messages to people who aren't currently online;
• a proxy for the Debian Advanced Packaging Tool system; and
• a probabilistic mechanism for sharing common keys between nodes, something not present in all DHT implementations.

Its DHT implementation is vulnerable to denial of service attacks.

:The Circle is a scalable decentralized peer to peer application.... There's no central authority running the show. Which means no entry taxes, no one booting you off the network, and (in theory) no weak point which can break the whole system. As long is there's one Circle peer running, anywhere in the world, there's still a network. Circle does not try to provide anonymity, which allows it to be much more scalable than gnutella.
