in opinion, would it be possible to implement yr solution without blockchain or is such an option excluded?
I think putting the idea of education behind it makes them think everyone would by in. Almost like saying its helps feed the poor, homeless etc. I honestly believe that if you want to make money don't use the less needy to do it.
Some aspects of the project could be developed without the blockchain, but not all of them or at least not as efficiently as with using the blockchain, such as immutable store of the achievement records, curriculum snapshots, certification of content providers, micro payments, payment ecosystem for lectures, scholarships, mentorships etc.
