This smells of trouble to me. There already are platforms that deal with online courses and are not blockchain based. Is there a need for blockchain even?
Yes, blockchain makes it unhackable and fraud protected (just to mention two benefits of blockchain in this area)
I wanted to know at what stage of development is now your product? If for any reasons the launch of core platform will be delayed, you will seek new partnerships to create a database? Have you considered this option in principle?
There will be a first working product very soon!
