P2P File System

Secure Distributed File System

Imagine a file system with seemingly limitless space, that can be accessed from anywhere securely. Imagine a network not about file sharing, but instead resource sharing. Imagine a P2P Secure Distributed file system, like SETI@HOME in the business of storing your files instead of searching for ET.

The system would involve a small app that runs on your desktop and accepts a certain amount of data that others have added to the network. From that app you could also post data to the network. For example if you were to upload a 60 MB video file from your digital camera, it would be split up into 60 pieces to be stored on around 600 different computers (10 available copies of each piece). Each would be encrypted with your password and would be tagged with your user name so that no one else could access them.

But what about storage limits? Well users would gain points for the amount they allow to be stored, the amount of uptime they provide, and the amount of bandwidth they allow to be transferred. The more they give to the network, the more they'll get out of it.

There would have to be a central authority in charge of handling the base metadata, and perhaps providing a cluster of P2PFS servers for added redundancy and guaranteed network uptime. But beyond that it would all depend on the users of the network. Like SETI@HOME, the machines would dedicate more resources when idle.

Linux versions could be made to boot off live CDs, and run off RAM for computers that desire to be dedicated to the task without wasting ANY HD space for overhead.

See link for more technical details and a description of my inspiration.

Tahoe LAFS https://tahoe-lafs.org/trac/tahoe-lafs
Tahoe-LAFS is a Free and Open cloud storage system. It distributes your data across multiple servers. Even if some of the servers fail or are taken over by an attacker, the entire filesystem continues to function correctly, including preservation of your privacy and security. [fho, Nov 18 2011]

       Is data storage really so expensive (and bandwidth so cheap) that it would be practical to implement this?   

       Also, there are plenty of online storage services available (google offers at least a few gig for free) which seems to make this somewhat redundant.   

       I suppose this system could be useful for security reasons (i.e. data not in one easy-to-steal location).

       Another added benefit is the redundancy, and universal availability.   

       As far as other services. Gmail offers storage only 10 MB at a time, and doesn't allow all file types without screwing around with it first. Plus, as my blog notes, Gmail lacks the sheer geek factor that a P2P system would have.

       I know i am years too late ... but this has been baked since 2005. See tahoe-lafs link.
