167 Figure 8.4 : Link state when X sends communication to non-friend Z is shown (a) before the token is issued, (b) after the token is issued, (c) if Z marks the communica- tion as unwanted, and (d) if Z marks the communication as wanted or if the timeout occurs. It is worth noting that the intermediate users along the path are largely indifferent to the outcome of the transfer, as any credit transfer will leave them with no net change. For example, consider the scenarios shown in Figure 8.4 (c) and (d). In either case, the total amount of credit that intermediate user Y has with all her friends is the same regardless of the outcome. If Z marks the communication as unwanted, as shown in Figure 8.4(c), Y owes a credit to Z, but X now owes a credit to Y . Ostra allows users to transfer credits along trust paths such that intermediate users along the path are indifferent to the outcome. Generalization of Ostra strawman One can show that Ostra generalizes the strawman design from the previous section. Recall the account C that is owned by the trusted site. Now, we construct a trust network in which each user has a single link to C, with the link balance and balance range equal to their user balance and balance range in the strawman design. Ostra with such a trust network has the same properties as the strawman design.
