No, AES everywhere, and DSA, and Diffie-Hellman (soon to be STS). > 2.

Identity = 32-byte opaque node unique identifier. Not used for routing. Location = Double precision number between 0.0 and 1.0. Swapped by the location swapping algorithm. We ASSUME that the network topology is correct, and use a variant of the Metropolis-Hastings algorithm which Oskar came up with to assign locations such that greedy routing (always route to the node whose location is closest to the target) works. > 3.

A very good question! The answer is "with difficulty". Probably we will divide the network into cells and expose the topology within those cells; then the node would pick two nodes at random from within the cell, and onion wrap the request to the two nodes, and pass it to a random direct peer. > > In any case i`lll be uploading my efforts onto freenet itself & also the > web, to serve as a beginner-friendly guide for tyros > Looking forward to hearing from you guys.
