In a digital social relationship network, a social network server computer stores a digital social network representation corresponding to a graph having nodes representing individuals or groups and links representing actual social relationships between the individuals or groups. The server computer obtains relationship-dependent information corresponding to a plurality of links of the graph, and embeds the relationship-dependent information in the digital social network representation stored in the social network server computer. The server computer interactively presents to a user of a client computer connected to the social network server computer a social network of the individuals or groups and the social relationships between the individuals or groups. The social network server computer receives input from the user of the client computer selecting at least one of the social relationships between individuals or groups other than the user, and presents to the user of the client computer a social relationship profile comprising the relationship-dependent information corresponding to the social relationship selected by the user of the client computer. The server computer facilitates exchange of digital value to the user of the client computer, or a group to which the user of the client computer belongs, based on the relationship-dependent information embedded in the digital social network representation stored in the social network server computer.
