MeV blazars are the most luminous sources in the Universe and host supermassive black holes. An MeV survey will detect >1000 of them up to z > 5. This would allow us: to probe the formation and growth of massive black holes at high z; to pinpoint the emission region location in blazars; to determine the interplay of accretion and black hole spin.
