This paper introduces the N-party BAR Transfer service. The service aims at transferring data from a group of replicated producers to a group of replicated consumers, in a setting where the behavior of the participants is characterized by the Byzantine Altruistic Rational (BAR) model. The problem is motivated, a precise definition of problem is presented, and the challenges on solving the problem are discussed.
