How does it work?

Retroshare is a network of computers. These computers we call nodes and every user has its own node. Neighbors only know the exact location (the IP-address) of nodes. You invite someone to become a neighbor by sending your public key.

Forums use pseudonymous nicknames to identify people. The nickname system uses cryptographic keys to verify messages come from specific authors. The nickname information travels wherever the forum post goes.

If you send a message to a user, the system delivers it to his node by searching for a route by forwarding it via a chain of neighboring nodes. If you want a certain file, your node asks your neighbors and they in turn request it from their neighbors.
