This (19 page PDF) is a pretty good and very detailed description of a use case for blockchain technology in education, and specifically, a mechanism for supporting the use of digital labs by students working in a learning management system (in this case, Moodle). The parameters for access and use of the lab are established using an Ethereum smart contract, while data is linked from the blockchain and stored using the interplanetary file system (IPFS), which provides robustness against single-point failures or intrusions. The difficulty with this approach (in my view) is that the technology it's using might not be more reliable than the technology it replaces, and there are in addition cost overheads (in the form of Ethereum gas fees) to consider.
