The Verifying Hashes, in an AICH supporter client, are those which aren't neither Block Hashes not the Root Hash.
Each Verifying Hash is calculated out of the concatenation of the SHA1 hash strings of the Verifying Hashes or Block Hashes in the level right beneath (in the AICH Hashset tree).
Their purpose are to make a client easier to know if the recieved Block Hashes are fake/corrupt or not by sending those Veryfing Hashes, instead of all the Block Hashes of a file, when no Block Hashes in the levels beneath that Verifying Hash (in the AICH Hashset tree) have been asked by the client.
This avoids both using more bandwidth and CPU cycles on the remote (recieving) client.
