 An important development to keep a network clean from sybil and malicious
 attacs it's a way to blacklist and detect malicious storage nodes

 A malicious storage node it's defined like a node that it's saying that
 it's storing data, but it isn't.

 Those parts of files that it's reciving, are lost.

 To prevent malicious storage nodes, each client will check file integrity
 to be sure files are accessible.

 Client keeps a relation of parts uploaded to each node. When a storage
 node where file were alocated there, is not giving the file, or it's
 answering it doesn't have your file or is not online, after few retries in
 different days this node it's marked as malicious.

 Each client will have a list of what he detected as a malicious storage
 node.

 Those list can be done in the introducer,too. In this way, introducer
 would prevent to notice about a malicious storage node to possible
 clients.
