The Circle (file system)
The Circle is a
Chord distributed hash table
(DHT).
Development on the Circle was ceased in 2004.
Features
It supports file sharing,
Internet Relay Chat
model of sending a message to a channel, and a personalized, trust-based news service.
More unusually, it supports:
- finding and sending messages to people who aren't currently online;
- a Advanced Packaging Toolsystem; and
- a probabilistic mechanism for sharing common keys between nodes, something not present in all DHT implementations.
Details
Its DHT implementation is vulnerable to denial of service attacks.
From The Circle homepage:
- 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.
The Circle currently runs on
Mac OS X
