Blockchain defined: Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding). Virtually anything of value can be tracked and traded on a blockchain network… ~ IBM

One place that I see blockchain technology being used in education is credentialing. Right now a general arts degree at a good university is a credential that says, ‘I know how to study, write essays, and express my ideas’. Unlike professional programs like engineering or law or med school, a general arts degree is about building more general skills. More and more jobs are not requiring a professional focused degree, but also demand more specific skills than a general degree.

Can a potential job candidate manipulate pivot tables in Excel? Or understand the basics of coding in python? Or use a design thinking process? These questions aren’t always answered by a degree, and might be answered by a certificate. What if Microsoft or other large companies delivered skill-based credentials through online courses? What if when you received certification of completion of the course, you didn’t just get an easily copied and doctored paper certificate, you also got digital certification that could not be doctored by you, but could be verified by anyone?

Imagine having a digital portfolio that linked to all your credentials in immutable ledgers. Your skills could be verified and job descriptions could include expectations of specific skills and credentials. What do you know? What can you do?

So, maybe in the future a college degree will be less impressive than a series of verifiable skills. Maybe high school students will start getting these credentials before they graduate. To me this had a few implications to think about:

1. If we move to a more skill-based economy, how will this affect our school curriculum?

2. If credentials and credentialing become a major driver to workforce hiring, will this force more specialization in high schools?

3. Where does that leave the soft skills like communication, critical thinking, and creativity?

Some people think that credentialing like this can replace teachers, I don’t. I think teachers become more valuable. Let credential testing and digital training measure the skills that are easily measured, and let teachers loose on helping students be more creative, more entrepreneurial, and better problem solvers. Let teachers focus on helping students trying things that are epic, things that are so big they are likely to fail, and help students understand perseverance. Have teachers focus on developing communication and cooperation skills, and helping students understand the importance of learning and process.

Credentialing won’t diminish the role of the teacher, it will magnify their importance in creating leaders and problem solvers. And to me, that’s the more exciting part of being a teacher.
