Blockchain Basics for Program Managers
During the last few years, blockchain has sucked a lot of air out of the room with respect to security and systems design. Among other things I have heard include blockchain will cure world hunger, blockchain is the future of colleges, and something about blockchain is the future of Social Security. All of this, and a lot more nonsense can be found here: https://decrypt.co/4936/ridiculous-things-blockchain Blockchain will not cure cancer and it will not do your laundry. But that does not mean it does not have some uses. For government IT managers, understanding what blockchain is, how it works, and what its role in the data storage ecosystem is critical for evaluating enterprise architectures and proposals for new systems. Accordingly, at JHU/APL, we worked with DHS to develop a white paper to do exactly that and I am quite happy to say it was published in the Journal of Information Technology Management, last night. The most fun part of this is figure 2. DHS shared our flowchart with NIST and they put it in NISTR 8202, and they put it everywhere! https://www.google.com/search?q=nist+blockchain+flowchart Anyway, you can read the paper in the latest issue of JITM, here: http://jitm.ubalt.edu/XXX-3/contents.html It is aimed at government managers, but, really, every IT manager should read it!
