A Big Thank You to My OLLI Students!

Notionovus Blockchain Class

For those of you visiting this site to view the links I mentioned in my last lecture, here they are:

First of all, if the graphic wasn’t hokey and looked professionally done, I got it from Unsplash or Wikimedia Commons. I tried to credit the origin of each picture from either of these fine sites. The opening splash screen and a few of the early graphics were created in Adobe Spark, so no attribution supplied or needed.

If, on the other hand, the graphic was just a bunch of crudely drawn blocks and arrows and the text was in Comic Sans, then I take full responsibility for creating those messes.

For much of the material and narrative in the class I can’t really site every book or website I read. I can recommend a book that I finished recently, that I really liked: The Truth Machine: The Blockchain and the Future of Everything.

I will also recommend two books that I read previously that I garnered quite a bit of wisdom from: Mastering Bitcoin: Programming the Open Blockchain and Mastering Ethereum: Building Smart Contracts and DApps.

A good article to read about the history of the Bitcoin phenomenon is Joshua Davis’ piece in the New Yorker about his search for the inventor of Bitcoin.

Of course, one of the best places to start when it comes to crypto-currency and even blockchain are the tutorials at Coindesk. Their Beginner’s Guide is one of the resources I used to cut my teeth on this blockchain thing and, so can you! The lessons are very accessible.

Trading heroes also has a pretty good getting started guide to crypto-investing.

Once you’ve been through Coindesk’s free courses you’ll probably want to head over to coinmarketcap.com to check out the crypto-currency markets. You can find more detailed information there about certain crypto-technologies as well as the marketplaces that will help you trade in and out of currencies.

We talked, briefly, about Initial Coin Offerings, but I don’t think I had time to actually bring up icorating.com. This site will give you a heads up about specialty coins that are about to be released in the wild. There are plenty of lessons to be learned here about ICOs.

The Ethereum Project and Foundation can be found at ethereum.org. They are loosely related to Consensys, which is an interesting set of applications spinning up on the Ethereum blockchain.

Another interesting blockchain research play is the activity going on at Hyperledger. Hyperledger is sponsored by the Linux Foundation, but it has a bunch of high-tech heavy hitters involved in very visible projects.

You’ll find out more about Ripple at their website, but also at their YouTube channel at: https://www.youtube.com/channel/UCjok1uTSBUgvRYQaASz6YWw.

We spent a little bit of time talking about what I believe may be one of the most impactful blockchain / crypto applications yet. Brendan Eich’s Brave Browser and the Basic Attention Token. If you haven’t at least tried this browser, I think the time not spent on downloading ads and finding the real content on pages helps this free browser pay for the inconvenience of downloading and installing.

Finally, in no particular order are a bunch of online articles about using blockchain technology for supply chain transparency:


















Why blockchain won’t fix food safety—yet




I almost forgot the cryptomining demonstration software on my codepen. A crude but effective hands-on way of teaching someone the rudiments of mining.

Thank you for attending my Blockchain class. I hope everyone benefited from the experience as much as I did. Feel free to join me on LinkedIn, Facebook or twitter.
