N2 - We generalize the definition of Proof Labeling Schemes to reactive systems, that is, systems where the configuration is supposed to keep changing forever. As an example, we address the main classical test case of reactive tasks, namely, the task of token passing. Different RPLSs are given for the cases that the network is assumed to be a tree or an anonymous ring, or a general graph, and the sizes of RPLSs’ labels are analyzed. We also address the question whether an RPLS exists. Interestingly, for the anonymous ring, it is known that no token passing algorithm is possible even if the number n is known. Nevertheless, we show that an RPLS is possible. We show that if one drops the assumption that n is known, the construction becomes impossible.
