Oh, sorry but let me quote it for you in case you didn't read the first post in this thread.
Atlantis Blue shows yet another real-world application of cryptocurrency, securing Larimar, a semi-precious gem. This stone is found only within a particular dead volcano on the Caribbean island of Hispaniola, alongside the Dominican Republic. Larimar is also known as the Blue Stone of Atlantis, hence the name for the platform.
I hope that's much clearer now, if you can help me with my question then that is much appreciated but if you can't then I think you are the one who is lost.
