@ -30,8 +30,9 @@ This version of Tahoe will tolerate directory entries that contain filecap
formats which it does not recognize: files and directories from the future.
Previous versions would fail badly, preventing the user from seeing or
editing anything else in those directories. These unrecognized objects can be
renamed and deleted, but obviously not read or written. This should improve

At a high-level this system consists of three layers: the grid, the
filesystem, and the application.
The lowest layer is the "grid", a mapping from capabilities to data.
The capabilities are relatively short ascii strings, each used as a
reference to an arbitrary-length sequence of data bytes, and are like a
URI for that data. This data is encrypted and distributed across a
number of nodes, such that it will survive the loss of most of the
nodes.

The middle layer is the decentralized filesystem: a directed graph in
which the intermediate nodes are directories and the leaf nodes are
