I still can not believe I take an entire blockchain course from MIT fo free, unbelievable. I can not thank enough MIT.

[@blahblah6497]

Well, you can catch a Lecture, possibly a few different lectures, which I agree is Awesome! Any info, especially free info, extra Especially really good free info... Is ALWAYS welcomed and sincerely appreciated. However, it is definitely lacking compared to taking the class for real. You miss other things like tests, mid terms and finals... All are a Pain in the ass, however it accounts for a significant amount of the information a student will aquire, as the average student will spend 2-3 times the amount of time studying for Mid-terms and Finals, than the average study period. Which accounts for about 1/3 of the information learned in the class. Also, we don't have the benefit of the assigned Texts or Syllabus (if he assigns one.. though there's probably not much reading for this class).

[@mitocw]

@@blahblah6497 Visit the course MIT OpenCourseWare for the Syllabus and a list of Readings at: ocw.mit.edu/15-S12F18. We try to get other materials from the instructors (like exams). We publish what they are willing to give us. Best wishes on your studies!

[@buzzpedrotti5401]

A year after viewing this course and the FTC, SVB and Credit Suisse failures, I have retained the following. 1. A distributed accounting ledger is created that does not require a central responsible owner. 2. An system of creating an increasing but limited number of tokens allows users to agree on value through a market, so it can be used as money, a store of value and a medium of exchange. 3. Combining these two allows the creation of competing systems that may have the promise of lower transaction costs and perhaps less government control than other forms of tender. 3. In it's infancy, significant challenges remain. I term these infancy risk, promise risk and unknowns risk.

[@SC-do8mo]

Appreciate the interaction between the students and the professor in order to set up his slide. This is something that seems to be common place in US higher education. It keeps the course lively. Here in the EU, many maintain the idea of writing down what you see on a presentation, and having work on slides -> memorize and dig in if you have time. It works but interaction is lacking. Notice how he asks for the first name? These are tiny details that make a difference when you are in the audience. I've been taught by both systems.

[@Garrettm31]

In many US class there is a focus on discussion and is considered a better class when students are more interactive

I am so very grateful to have these university courses available for free. For the last few years I've been researching and studying crypto currencies, blockchain, buying, selling, trading, using exchanges as well as all the lingo etc... Just teaching myself. It seems every other youtuber (with a channel on crypto and such) is offering their own form of online courses to purchase for hundreds of dollars and up, and their idea of what is correct and helpful is questionable at best. So this is such a wonderful opportunity for me (and others) to finally get a great education at the university level, on this extremely important subject matter! I'm going to have a very busy rest of the year, who knows I might never stop school! lol. Thank you -
