Blockchain https://en.wikipedia.org/wiki/Blockchain is in the news daily - most often in relation to crypto-currencies. Other applications are also being explored https://www.sitepoint.com/blockchain-top-uses/.
As learning leaders and technologists focused on assuring business outcomes - does blockchain matter?
I worked on a project at UnitedHealthcare to blockchain professional skills via internal badging and educational institutions/universities. The goal was to accelerate selection decisions (hiring, promotion, work assignments...) and improve selection success through skill verification. It was a promising project. Some universities were already working on badging initiatives, foremost being University of Indiana. The UPCEA (University Professional Continuing Education Association) was exploring badging at the time, but I haven't heard much about it recently. The project didn't get approval to move beyond an internal badging test, which didn't include blockchain tech.
