In this talk, I discuss the limitations of current SMR protocols, which depend in some way on the existence of honest-by-default participants, particularly in the age of tokenised SMR protocols. I outline the ByRa model, a framework for player characterisation free of honest participants, and introduce the properties of strong incentive compatibility in expectation and fairness, that are necessary and together sufficient for achieving SMR in the ByRa model.
