Friend-to-friend¶
A friend-to-friend (F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know.
Core Idea¶
Friend-to-friend is treated here as the recurring computerscienceandinformation identity summarized by this source-grounded definition: A friend-to-friend (F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know. A friend-to-friend (F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know. Passwords or digital signatures can be used for authentication. Unlike other kinds of private P2P, users in a friend-to-friend network cannot find out who else is participating beyond their own circle of friends, so F2F networks can.
Scope of Application¶
-
Documented setting. Retroshare, WASTE, GNUnet, Freenet and OneSwarm are examples of software that can be used to build F2F networks, though RetroShare is the only one of these configured for friend-to-friend operation by.
-
Documented setting. Passwords or digital signatures can be used for authentication.
-
Potential applications of F2F. The Bouillon project uses a friend-to-friend network to assign trust ratings to messages.

Documented setting. Unlike other kinds of private P2P, users in a friend-to-friend network cannot find out who else is participating beyond their own circle of friends, so F2F networks can grow in size.
Clarity¶
A clear use of Friend-to-friend names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is A friend-to-friend (F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know.
Manages Complexity¶
Friend-to-friend compresses multiple computerscienceandinformation details into a stable diagnostic relation. The source shows both the central mechanism—the Bouillon project uses a friend-to-friend network to assign trust ratings to messages.—and the practical consequence—for example, a node in a friend-to-friend overlay can automatically forward a file (or a request for a file) anonymously between two friends, without telling either of them the other's name or IP address.
Abstract Reasoning¶
- Type the carrier. Identify the computerscienceandinformation entities to which the claim applies.
- State the relation. Use the source-grounded identity: A friend-to-friend (F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know.
- Check operation and conditions. A friend-to-friend (F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Friend-to-friend transfers literally when a new case preserves the same carrier type, relation, and recognition test. Retroshare, WASTE, GNUnet, Freenet and OneSwarm are examples of software that can be used to build F2F networks, though RetroShare is the only one of these configured for friend-to-friend operation by default. Passwords or digital signatures can be used for authentication. Beyond the home domain. No canonical parent is asserted for Friend-to-friend.
Neighborhood in Abstraction Space¶
Friend-to-friend sits in a sparse region of the domain-specific corpus (94th percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
