Wow, that's a new use for the blockchain, and like you said uploading notes on the chain for the students is a novel idea.
The other thing that I can suggest is that you can upload the notes on Steemit and ask your students to access them through their mobiles using @partiko app. Easy to download on mobile and 100% access to Steemit. That way you can by pass your government's actions of stealing the university computers. Well, what I don't know is the availability of phones for your students. If they have you can try this out.
