We describe a design for a reputation system that increases the
reliability and thus efficiency of remailer services. Our reputation
system uses a MIX-net in which MIXes give receipts for intermediate
messages. Together with a set of witnesses, these receipts allow
senders to verify the correctness of each MIX and prove misbehavior to
the witnesses. We suggest a simple model and metric for evaluating the
reliability of a MIX-net, and show that our reputation system improves
over randomly picking MIX paths.
