![]() ![]() Instead, each peer maintains its own trust for each of its local links. GNUnet network has no trusted entities so it is impossible to maintain a global reputation. The idea of employing an economic system is taken from the MojoNation network. GNUnet provides trust system based on an excess-based economic model. ![]() The communication port, officially registered at IANA, is 2086 ( tcp + udp). Now GNUnet transport subsystem provides multiple options, such as TCP and SMTP. Originally, GNUnet used UDP for underlying transport. Gnutella is not an official GNU project, while GNUnet is. GNUnet is unrelated to the older Gnutella P2P protocol. GNUnet includes various P2P applications in the main distribution of the framework, including filesharing, chat and VPN additionally, a few external projects (such as secushare) are also extending the GNUnet infrastructure. On top of the core subsystem various applications are built. Transport subsystem provides insecure link-layer communications, while Core provides peer discovery and encryption. GNUnet consists of several subsystems, of which essential ones are Transport and Core subsystems. It has gained interest in the hacker community after the PRISM revelations. The primary codebase is written in C, but there are bindings in other languages to produce an API for developing extensions in those languages. Gnunet://module/identifier where module is the module name and identifier is a module specific string. GNUnet URIs consist of two major parts: the module and the module specific identifier. GNUnet uses Uniform resource identifiers (not approved by IANA, although an application has been made). The users' friends' own friends (and so on) can then indirectly exchange files with the users' computer, never using its IP address directly. GNUnet offers a " F2F topology" option for restricting connections to only the users' trusted friends. GNUnet includes a distributed hash table (DHT) which is a randomized variant of Kademlia that can still efficiently route in small-world networks. GNUnet's basic network topology is that of a mesh network. The framework offers link encryption, peer discovery, resource allocation, communication over many transports (such as TCP, UDP, HTTP, HTTPS, WLAN and Bluetooth) and various basic peer-to-peer algorithms for routing, multicast and network size estimation. GNUnet is a software framework for decentralized, peer-to-peer networking and an official GNU package.
