I just earned a “Blockchain Essentials” Digital Badge – for free (and it was fun)
Kudos to IBM for putting together great mini-courses that are free to everyone and provide digital badges upon completion. I got a solid introduction to Blockchain Essentials while also earning my first Digital Badge, in just a couple hours. It was a fun experience. I look forward to taking another one of these little courses:Â https://developer.ibm.com/courses/all/!
Many of the courses are pretty techy, but some less so, like the Blockchain Essential course.Â These was a nicely done course consisting of mostly short video clips followed by “check points” requiring users to validate their understanding of learned facts. These were not super-challenging, and participants get multiple attempts at finding the right answer to these multiple choice questions. The bigger challenge was a hands-on lab in which you had to change some default values in pre-formatted JSON code blocks. To finally earn the badge you had to get 8 out of 10 questions on a quiz correct.
I came away with solid overview of “Blockchain Essentials” and learned things I did not know. For example, I developed a considerable appreciation for the extent to which Blockchain is quickly being adopted for use for supply chain management in numerous industries. I also learned about the vast and growing open Linux Foundation's Hyperledger Project (with 140+ major cross-industry organizations involved) and the open Hyperledger Composer.
Upon completion, I earned a Digital Badge, which can be viewed here.
I highly recommend that those interested in tech take a look at IBM's free courses.
