GNUnet's identity management is built around the following principles:

• Public key pairs as "egos" to identify users.

• Multiple alter-egos (pseudonyms) per user, enabling identity separation.

• Independent from peer identities, meaning network addresses do not determine user identities.

GNUnet includes a decentralized Name System with key features:

• Secure, memorable names in a fully decentralized system.

• Delegation to achieve transitive trust.

• Globally unique, secure identifiers for names.

• Privacy-focused queries and responses.

• Alternative to traditional public key infrastructure (PKI).

• Interoperable with DNS.

• Simple API:

  • GNUNET_GNS_connect()

  • GNUNET_GNS_lookup()

GNUnet supports an efficient revocation mechanism with the following properties:

• Instant revocation at all peers that the network permits to receive it.

• Highly efficient protocol for propagation.

• Offline revocation messages—can be pre-generated and stored.

• Trivial API:

  • GNUNET_REVOCATION_revoke()

  • GNUNET_REVOCATION_query()

GNUnet integrates PSYC2 and GNS to support decentralized social networking applications.

Key concepts:

• nym → A pseudonym of another user in the network.

• place → A virtual space where social interactions happen.

• host → The owner of a place.

• guest → A visitor in a place.

The API provides a vocabulary for managing social interactions:

• enter, leave → Users joining and exiting places.

• host_eject, host_entry_decision, host_announce → Host controls over guests.

• guest_talk → Communication within the place.

• place_history_replay, place_look_at → Interaction history and visibility.
