Abstract

Once information is stored on the Blockchain, it cannot be altered retroactively. This immutability makes Blockchain technology an ideal candidate to secure learning achievements and educational credentials. Keeping data trustworthy, secure and manipulation-proof has become an increasing issue in education due to the rise of digital learning environments, which often combine learning experiences, testing procedures and educational credential management. Currently, most digital learning environments safeguard their data using traditional safety systems (e.g. password protection), which in turn are not Blockchain-based, but controlled by a centralized authority. While These centralized systems provide a certain level of security against unauthorized access from outside the system, manipulation from within the system cannot be excluded. Users with high enough Access rights (teachers, administrators, system managers) can still add, change or delete entries. This becomes an even greater problem when learning achievements are to be reflected in fair and transparent credit systems, and especially when these educational credits are to be valid across different institutions or even countries. Due to their ability to store data in a decentralized, transparent and manipulation-proof way, Blockchain-based technologies can provide solutions to this problem. The aim of this paper is to describe the status quo of Blockchain technologies in the educational sector, including the expected merits and drawbacks.
