Freenet

Freenet

1. Search

   • Peers try to intelligently route requests Peers ask neighbours like Gnutella BUT
   • peers DO NOT FORWARD requests to all peers. Peers find the closest key to the one supplied in their local routing tables and pass the request only to this peer.
   • At each hop keys are compared and request is passed to the closest matching peer.

2. Difference

   • Freenet peers do not store locations of files. Instead they contain file keys that indicate the direction in key space where file is likely to be.
     • Three types of keys
       • KSK - Keyword-Signed keys
         • The simplest of Freenet keys Derived directly from a descriptive string that the user chooses for the file
       • SSK - Signed-Subspace Keys
         • Used to create a subspace To define ownership or To make pointers to a file or a collection of files
       • CHK - Content-Hash Keys
         • Used for low-level data storage Obtained by hashing the content of the data to be stored
