We discuss a non-equilibrium statistical system on a graph or network. Particles are injected, interact with each other, and traverse and leave the graph in a stochastic manner. We show that under the assumption of constancy of a subset of parameters, the system demonstrates the universality of the statistics of the particle currents. In systems connected to a heat bath, this universality leads to fluctuation relations that forbid distinguishing stochastic currents in a strongly driven regime from the currents in thermodynamic equilibrium. We apply this universality to enabling examples from mesoscopic electronics and biochemistry.
