[tahoe-dev] Fwd: [p2p-hackers] [ANN] libchop 0.2, a library for distributed storage and data backup

[Zooko Wilcox-O'Hearn]

Folks:

Ludovic Courtès was the curator of a bibliography of research papers  
on "cooperative backup" which was linked from our Bibliography page  
[1], he did his PhD thesis on cooperative backup [2], and he recently  
packaged Tahoe-LAFS for NixOS [3].

He just posted this release announcement of a new version of his  
"libchop" library, which he originally implemented as part of his  
thesis.

Regards,

Zooko

> addressing,
> content hash keys, Merkle trees, similarity detection, and lossless
> compression.  It makes it easy to combine them in different ways.  The
> ‘chop-archiver’ tool provides access to these features from the  
> command
> line; along with ‘chop-block-server’, it allows for remote data
> storage.  Example uses of these tools are given in the manual.
