Yes, blockchain technology can be used in the education sector too. I just learned the research if blockchain is implemented that can save a lot of educational data. for example in college, there's a lot of data that they have to store manually on PCs and libraries but sometimes it is not effective, because the Old data is often deleted if any new data comes to be saved. So if blockchain technology is implemented for purpose, I really sure the data will be forever on blockchain and can be checked it by the public.
