Description (last modified by davidsarah)
The Merkle Tree over the shares is stored on each of the N servers. If a server has the correct share, but its copy of the Merkle Tree over the shares has been corrupted, then the downloader could download the share and check it using a copy of the Merkle Tree which was downloaded from a different server.
However, currently the downloader stops using a server entirely if it has a corrupted Merkle Tree, so the downloader might fail to download the file since it doesn't try to use the share from the server that has the corrupted Merkle Tree.

Hmm, how likely is it that a server would have a correct share with a corrupted Merkle tree? I'm not sure this would help much in practice.
