I don't know it seems like a great idea but if you're having a prize by just hunting a bounty, then for sure students would cut classes just to focus for that bounty. I think it would be better to still connect the subjects to some bounty for them to still focus on studying and the class. There's already a lot of universities that teaches crypto industry and blockchain technology. There's no need for them to force or encourage them with a task just because there's a prize. If they want to learn something they would search for it. Just give them some enough money for a good start consider it as part of the scholarship for the courses under crypto subjects. It can already be consider as work when you're trying to understand and doing stuff just for money.
