User Profile Challenge and Delivery
Introduction
Community is an important part of a peer to peer experience, and a unified user profile format enables meaningful exchange of user metadata. Gnutella user profiles are XML documents adhering to a user profile schema referenced below.
User profile information is exchanged at strategic points in network communications, using packet types defined in subsequent sections.

Profile Challenge and Response/Delivery
Requesting a user profile from another user involves a challenge and response transaction. The challenge step allows the initiator to provide a random token for the respondent to sign with a digital signature and return, verifying its identity. This allows a distributed identity safeguard, which is under development.
