Cryptonight Dark algo is not distinctive, exclusive and not new.
It was used in other coins.
But it looks like other coins with this algo was dead...
I do not claim that it was created specifically for my coin. Initially, it was used only in Cryonote and nowhere else. Later this project was closed. Now the algorithm is used only in BlackRose, which makes it a kind of exclusive algorithm. This algorithm has not been used anywhere else and is not used to this day.
