"I want people to see the truth... regardless of who they are... because without information, you cannot make informed decisions as a public" -- Bradley Manning

The Cryptosphere is a global peer-to-peer cryptosystem for publishing and securely distributing content anonymously with no central point of failure. The system is openly federated and anyone can join. To ensure quality service and prevent abuse, the Cryptosphere uses an integrated cryptographically secure reputation system which provides a distributed web of trust.

There are several systems with similar goals to the Cryptosphere, such as MNet, Freenet, and Tahoe-LAFS. These systems serve as inspiration for the Cryptosphere's design. The Cryptosphere is also heavily influenced by Git, the distributed version control system.

For more information, please see the project philosophy page in the wiki.

Is it any good?

Yes.

Is It "Production Ready™"?

No, the Cryptosphere is still in an early development stage, and is not yet ready for general usage.

Use Cases

The Cryptosphere provides an encrypted storage system where only users with the capability tokens for respective content are able to access it. Unlike many other peer to systems, there is no global search system because all content in the system is encrypted and therefore unsearchable.

This makes the Cryptosphere quite a bit different from many other P2P systems which sought to publicize users content. Instead, the Cryptosphere tries to keep your content as confidential as possible. This makes it useful for the following things:

• Secure personal backups
• File sharing among small groups (ala Dropbox)
• Secure anonymous encrypted source control
• Censorship-proof anonymous web hosting
