Abstract
A method of obtaining content includes receiving a playfile. The playfile includes a chunk ID corresponding to a chunk of the content, a packet ID corresponding to a packet of the chunk, and a hash of the packet. The method further includes obtaining the chunk from a peer, determining a calculated hash for the packet, and discarding the chunk when the calculated hash does not match the hash in the playfile.
