The other day we had an Eye-Opener about how Eastman Kodak - the same company that years ago hastened its own near-obsolescence by putting its pioneering digital photography research into a closet lest it hurt the company’s legacy film business - said yesterday that it is getting into the cryptocurrency business. Kodak said that it was using blockchain technology to create a new platform with its own digital currency.

I confessed that I’m not particularly good at explaining stuff like blockchain, which prompted MNB reader Jeff Gartner to pass along a site that he felt offered a particularly cogent and accessible explanation, from Northwestern University's Kellogg Insights newsletter.

I agree … and wanted to share it with you.
