ANNOUNCING: Allmydata-Tahoe version 0.7
|
|
|
|
We are pleased to announce the release of version 0.7 of allmydata.org
|
|
"Tahoe".
|
|
|
|
Tahoe is a secure, decentralized, fault-tolerant filesystem. All of
|
|
the source code is available under a Free Software, Open Source
|
|
licence (or two).
|
|
|
|
This filesystem is encrypted and distributed over multiple peers in
|
|
such a way that it continues to work correctlly even when some of the
|
|
peers are unavailable, malfunctioning, or malicious.
|
|
|
|
This is the successor to Allmydata-Tahoe v0.6.1, which was released
|
|
October 15, 2007 [1].
|
|
|
|
This release adds decentralized, encrypted directories and mutable
|
|
files, making it the first release of Tahoe in which no part of the
|
|
filesystem is centralized. It also adds a FUSE interface, allowing
|
|
you to access a distributed Tahoe grid as if it were a normal local
|
|
filesystem.
|
|
|
|
This is also the first release to be offered under a novel open source
|
|
licence which allows people to redistributed proprietary derivatives
|
|
of Tahoe for a limited time.
|
|
|
|
|
|
WHAT IS IT GOOD FOR?
|
|
|
|
With Tahoe, you can distribute your filesystem across a set of
|
|
computers, such that if some of the computers fail or turn out to be
|
|
malicious, the filesystem continues to work from the remaining
|
|
computers. You can also share your files with other users, using a
|
|
strongly encrypted, capability-based access control scheme.
|
|
|
|
This release is targeted at hackers and smart users who are willing to
|
|
use a web user interface, a command-line user interface, or a FUSE
|
|
interface. (Or a RESTful API. Just telnet to localhost and type HTTP
|
|
requests to get started.)
|
|
|
|
Because this software is new, it is not yet recommended for storage of
|
|
highly confidential data nor for valuable data which is not otherwise
|
|
backed up. However, it works well in practice, it comes with extensive
|
|
unit tests, and there are no known security flaws which would
|
|
compromise confidentiality or data integrity. (For a current
|
|
description of all known security issues and an overview of Tahoe's
|
|
security properties, please see the Security web page: [2].)
|
|
|
|
This release of Tahoe is suitable for the "friendnet" use case [3] --
|
|
it is easy to create a filesystem spread over the computers of you
|
|
and your friends so that you can share files and disk space with one
|
|
another.
