== Trust system ==

GNUnet provides trust system based on an excess-based economic model.{{sfn|Grothoff|2003}} The idea of employing an economic system is taken from the [[MojoNation]] network.{{sfn|GrothoffPatrascuBennettStef|2002|loc=2.4 Mojo Nation}}

GNUnet network has no trusted entities so it is impossible to maintain a global ''reputation''. Instead, each peer maintains its own ''trust'' for each of its local links.

When resources, such as bandwidth and CPU time, are in excess, the peer provides them to all requesting neighbors without reducing trust or otherwise charging them. When a node is under stress it drops requests from its neighbor nodes having lower internal trust value. However, when the peer has less resources than enough to fulfill everyone's requests, it denies requests of those neighbors that it trusts less and charges others by reducing their trust.
