Introducing the Blockchain principles to students is actually really good. However, In my opinion it will not properly work if we are going to add this on the Elementary and Jr. High Curriculum as it can be mandatory for all students to take this certain subject but can't actually help them.
Therefore the best option will be introducing it to Sr. Highs and in College. In which students will be able to choose if they get interested with this curriculum by that we can assure that students who were in the curriculum are interested and are willing to learn the blockchain technology
