3. Blockchain Basics & Cryptography

Congrats to everyone who's made it this far! It's interesting how the view count dips so fast the further into the series you get! If you consider the number of people that then do the corresponding readings, I'm sure it's even lower. Still, the knowledge is there for those of us willing to put in the time and effort! Blessings to all!

blew my mind, MY GOODNESSS, never have i ever had such a good lectures, i'm here binge watching blockchain lectures, never thought learning could this much fun and easy.

thank you MIT and Prof Gensler for this free lecture series! didnt think think I'd rather watch a college lecture than Netflix but now I know I do.

This lecturer is now the chairman of the SEC. I think it is a great appointment and it will give confidence to the markets for investment in the blockchain industry

It is a privilege to be able to listen to Gary Gensler for free like this. Don't forget that these.lectures were presented before he was chosen to head the SEC.

This guy understands this stuff so well that he is able to break it down and make it easy to understand. He is astoundingly intelligent.

I never thought I would ever be watching an MIT lecture and basically already understand all of it.

I am from Jamaica, can believe I am listening to a semester of lecture from MIT... Bless be God.. Thanks MIT

Idk it's nice to know that knowledge is free. And that the majority of people watching this have probably understood the ins, outs and the importance of btc and how money and society work in relation for a while. Any ways thank you MIT for the lectures!

I’m astonished by the quality of this lectures and it’s free! Thank you so much I really appreciate this MIT

Positive feedback to MIT open courses as a whole & Gary Gensler's class in particular. Thank you MIT for making this and your previous technical courses available. While I am typically a passive listener of educational content, professor Gensler and the student engagement in this course is really terrific. I feel obligated to provide the following feedback. For what is worth, here's my critique of the course so far. The first two classes had great tidbits about the history of money and finance...but I really enjoyed watching this 3rd lecture tackle the abstract concept of how (cryptography) algorithms could provide technical safeguards in the potential presence of an adversarial actor. Felt like the Prof was still looking for a more perfect/tangible analogy of a HASH value. Also (as with the previous lectures) I enjoyed the technical tidbits about how big a blockchain header is relative to the size of the blockchain. This lecture seemed to demonstrate the caliber of students at MIT in addition to the impressive professors.

This is the best way I have found to learn about this new tech. Doing the readings, the assigments and everything and the questions from the people there are really good too. Thanks for sharing it MIT.

Gary Gensler earned a whole new level of respect from me , this damn guy is a genuis

These slides are exceptionally good. Great learning curve and the professor makes learning blockchain very exciting. I would highly recommend anyone who wants to do anything with crypto to watch this course.

Its crazy how whenever I watch crypto vids I get funneled back to this playlist .I mean it makes since now that the guy is the head of the SEC I guess.Good job algorithm!

this lecture had been told to me to learn by my university as blockchain is my self paced course .It was really good lecture even though i was lacking on so many points in lecture i found it very interesting to eatch and not drop on some point i dont get.so i think he is one of the best teachers i had ever been taught ..hats off sir

It took me 4 hours to get through this. Thanks for the free content

A PRAISE FROM A 20 YEAR OLD BLOCKCHAIN LOVER (YES ME💓😃) :- Dear professor gensler , your COMPUTATIONAL power is really great. You are a genius, we love how you are defining this brutal technology in an interactive and fun way, I swear I'll attend all the classes and I'm also preparing notes and trying to do the homework you offer. THIS CONTENT WORTH MILLIONS OF DOLLARS. GREAT . WE ALL ASPIRANTS ARE BLESSED

Not a fan of cronies, but it is amazing that this guy is still learning complex new stuff in his 60s, most people in their late 20s give up on learning new stuff.
