We show that Naming- the existence of distinct IDs known to all- is a necessary assumption of Herlihy’s universality result for Consensus. We then show in a very precise sense that Naming is harder than Consensus and bring to the surface some important differences existing between popular shared memory models which usually remain unnoticed.
