Sure, we’ve all heard of bitcoin and how cryptocurrencies could revolutionize the way we conduct business online. You’ve probably seen the topic buzzing around on LinkedIn feeds or in just about any recent article touting future technology predictions. While many of us may not be making important purchases in bitcoin in the near future, the tech behind bitcoin–called blockchain–has the potential to influence our daily lives in more ways than one might think, including in higher ed.
What Is Blockchain?
You’re not alone if your head starts to spin when you hear the term blockchain. Despite being around for about a decade, many institutions are still struggling to grasp just what blockchain is–and what it can mean to higher education.
At the most basic level, blockchain is a database or digital ledger. The data in the ledger is arranged in batches known as blocks, with each block storing data about a specific transaction. The blocks are linked together using cryptographic validation to form an unbroken and unbreakable chain–hence the name blockchain. As it relates to bitcoin, the blocks are monetary units, and the chain includes information about all past transactions of that monetary unit.
Importantly, the database (i.e., the series of blocks) is duplicated thousands of times across a network of computers, meaning that it has no one central repository. This not only means that the records are truly public, but also that there is no centralized version of the data for a hacker to corrupt. In order to make changes to the ledger, consensus between all members of the group must be obtained, further adding to the system’s security.
If your head is still spinning, just know that blockchain is a public database for storing and sharing data records that creates a new level of trust in digital records and transactions that take place on the internet.
1. Blockchain for the Future of Credentialing
For higher ed–and even for our professional lives after graduation–blockchain has the potential to drastically impact the future of credentialing.
With today’s technologies, graduates and prospective employers must go through a tedious process to obtain student transcripts or diplomas, and this complexity is compounded when these credentials are spread across multiple institutions. Not only that, but these transcripts can take days or weeks to produce and send, and usually require a small fee be paid to the institution.
Some interesting work has been done around introducing standards to simplify this process with organizations like IMS, PESC and Groningen Declaration Network on digital exchange, but blockchain technologies could greatly simplify this process by creating a common, trusted digital platform for storing academic records for employment purposes and to support better student mobility between universities/country borders.
This could be a key enabler to facilitate student ownership of this data and would allow them to instantly produce secure and comprehensive credentials to any institute or employer requesting them, including information about a student’s performance on standardized tests, degree requirements, extracurricular activities, and other learning activities.
Blockchain could play a major role in Competency-Based Education (CBE) programs and micro-credentialing, which are becoming ever more popular across universities and internal business training programs.
Instead of providing paper certificates that are hard to verify, blockchain could help students to compile a complete digital record of all the training courses they’ve completed and certificates they’ve obtained that would exist in the public domain and be accessible on demand. As both these new forms of training take off in the higher ed and business learning space, blockchain credentialing is uniquely poised to help enable their roll out and acceptance by providing the means through which to track and share the certifications students have earned in various programs.
This reality is in fact closer than you might think, as various companies are currently working on such a system of record. One of the most well-known is called “BlockCert,” which is an open standard created by MIT Media Lab and which the institute hopes will help drive the adoption of blockchain credentialing. MIT not only has begun issuing digital certificates to students in the Media Lab, but envisions that such a system could help to digitally represent our professional lives as well.
For example, imagine the role that LinkedIn or a similar platform could play in the distribution of such content. Beyond verification of university records, LinkedIn could become a platform for sharing verified work history and resumes as well, making the job application process far simpler.
Of course, as such a system would have complete control over our professional representation in the digital space, we must think long and hard about the best ways to create and employ such a system, as well as the regulatory bodies that would need to be put in place to govern its existence.
