The Tahoe Least-Authority Filesystem (Tahoe-LAFS) is an open source, secure, decentralized, fault-tolerant, peer-to-peer filesystem[2]. It is being used as an online backup system by Least Authority Enterprises. It can also serve as a file or web host similar to Freenet[3], depending on the front-end used to insert and access files in the Tahoe system. Tahoe can also be used in a RAID-like manner to use multiple disks to make a single large RAIN pool of reliable data storage.

The system is designed and implemented around the "Principle of Least Authority" (POLA). Strict adherence to this convention is enabled by the use of cryptographic capabilities which grant the minimal set of privileges necessary to accomplish a given task to requesting agents. A Redundant Array of Inexpensive Nodes act as storage servers—these servers do not need to be trusted for confidentiality or integrity of the stored data.
