merkle-tree-verifier

Client generates files, calculates merkle root and unloads files to the server (deletes locally and uploads to the server).

Server accepts files to store, calculate merkle tree, when requested file, returns merkle proof.

Client when downloading file, can calculate merkle root hash from proof and be sure the file is not corrupted.
