Learning records represent the activities of learners on a learning platform. Because learning takes place at different institutions, organizations and/or platforms, it is important to connect learning records belonging to the same learner on these various platforms for a wider spectrum of analytics. With decentralization at the heart of the blockchain technology, we show the implementation of a blockchain based learning analytics platform. By using smart contracts, we enforce restricted access to learner’s data and empower learners with more control over their learning records. To ensure that learning records are immutable, we use a hashing strategy to detect changes between earliest version of a learning record and subsequently retrieved versions.
