Whats the difference between JM and Freenet?
Freenet is a distributed file publication system. In Freenet, each node (or “host”, or “computer”) has a cache of files and each file has a name. Nodes connect to each other to form a mesh (it is not specified how the host decides who its neighbors are in the mesh). The namespace in Freenet is flat and nodes can allocate names freely. Hosts can place files in their cache or any of their neighbors caches. If a host needs a file not in their cache, it asks its neighbor for the file. If the neighbor has the file, it gives the file to the requesting host. Otherwise, the neighbor asks one of its neighbors for the file. If that neighbor doesn’t have it, it asks the next neighbor, and so on. In this manner, the mesh is searched depth-first for the file (though there is a TTL on the search so that the entire mesh isn’t searched). It is not specified how a host decides which neighbor to ask for a file it needs. Note that to get a file it only needs to be in a cache _somewhere_ in the mesh. That
