Basic Design
Crowds works by making each node seem equally likely to be the initiator of the message. As we said each node joins the network by starting a jondo (from "John Doe"), which is a small process that will forward and receive requests from other users. When the jondo is started all nodes in the network are informed of the new node's entrance, and will begin to select him as a forwarder. To actually send a message a node chooses randomly (with uniform probability) from all nodes in the network and forwards the message to them. Upon receiving the message the node flips a biased coin (with probability ) and if it lands heads forwards it to another random node, otherwise it forwards it to the final destination. Each node when forwarding to another node records the predecessor and in this way a tunnel is built, this is used for the communication between the sender and the receiver.
