Purpose of Nano crystal coating in lenses?

I'm not 100% if Canon lenses has this coating, but I know Nikon's does. What is the purpose of this coating?

"Ghost and flare: Phenomena that occur due to reflection inside a lens barrel or camera. In the past it had been thought that it was impossible to eliminate the type of ghosts and flare that are caused by strong light entering the lens diagonally—even using various types of lens coating. Here we mark the arrival of the Nano Crystal Coat (as used on the AF-S NIKKOR 14–24mm f/2.8G ED, the first ever ultra wideangle lens)—a truly revolutionary technology that has greatly alleviated these problems—and focus on the men who developed it."

Yeah they all have their own versions. The old Magnesium Flourite coatings are to get rid of chroma and did nothing to end ghosting, or internal reflectiveness.

"Magnesium Flourite" just doesn't have the same sound appeal as "Nano crystal coating" :owned:

It dates back to Zeiss lenses in their T* coating (Carl Zeiss AG is the oldest surviving lens maker):
