The blockchain is a decentralized, internet-based digital ledger onto which organizations can record transactions. In the case of higher education, those transactions are academic accomplishments: courses completed, badges earned, degrees obtained. Blockchain is more widely used in other fields, such as logistics. And interest from the business community has spurred colleges to add the topic to their curriculum. Advocates of blockchain in higher ed say it can help give students more control over their records, allowing them to share the records in parts or fully with future employers or educators throughout their lives. For instance, MIT and Central New Mexico Community College offer students digital versions of their transcripts.
