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!

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

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.

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.

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.

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.

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

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

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.

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.

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

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

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 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

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 really is incredible, never thought I'd be so intrigued learning about block chain!

Thank you very very much for this series, I’m learning a lot. Those who want to dig deeper on RSA, hash functions, elliptic curve cryptography, and random-number generation can probably benefit from a specialized book on the subject.

Thank you MIT & prof. Gary Gensler.

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!

This is so interesting series of videos, that when I watching it during Im making my stocks analysis and is time to relax and play Diablo III I have a big problem to switch this video off and play game. Proffesor Gensler, you are great, and also the audience!

The information I learned from these 3 classes are very informative and fascinating. I appreciate everyone who made this far.

I am on the 3rd , lecture ... its great learning ...thanks MIT

What a strategy!...and now, Gary's the US-SEC Chairman!

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.

these classes are amazing. thank you for posting them!

Truly a hidden gem of KZfaq, thank you for the amazing content 👏👏

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

i feel much more motivated to dig deeper into blockchain after watching this lecture. best speaker for blockchain that i have encountered

Leaving my mark here at this mile marker. Thanks MIT and Professor Gensler. Peers, If you’ve made it this far, keep going!

Que gran curso! Me encanta, motiva y aprendo un montón, la calidad de la información y como esta organizada es perfecta. Saludos desde Argentina 🇦🇷

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

I make all the people that work in my office watch this MIT blockchain course. Then I give them a test. It helps to make sure when we have tech support problems I know all my people can at least think problems out in a group

this is a wild video, like outside of the informative nature of it. seeing Gensler talking about needlessly printing money a whole year before the pandemic, and noting one of the creators of Algorand over 6 months before it launched. shows have far we have come in only 3 years

What a great academic, so lucid presentation!

all this for free. lord what at time to be alive. just wished this series was recommended to me when it came out! but nonetheless very thankful

What a amazing method of teaching - No brainer why he is the SEC chairman

This class is so entertaining I’m awestruck

Thank you MIT for these amazing classes! 💐❤️

that base 2 to base 10 conversion trick/estimation at 35:55 was pretty genius and smart btw...for anyone who didnt catch that. shows hes pretty quick on his feet and knows quite a few math tricks

Cryptographic hashing is not only a way to take a lot of information and put it in fixed form, but The key thing is the hash functions tie the blocks together cause hash functions can point to previous info 1:13:11

thank you MIT for sharing this amazing course for free!

Thanks MIT for sharing knowledge with the world!

I love these videos. Thank You MIT

Congratulations on your new position Mr Gensler

This is a very helpful and clear class. Thanks.

Wow, this lecture series is amazing, thank you.

how does Gary retain all this knowledge ? unbelievable

Gem of a course. Good stuff prof..

Thank you I really appreciate the content. I am from Africa and to get this for free is heart warming.

That one was a brain buster for me. I fully understood about 60-65% of it at depth, and its ok.

Absolutely well done and definitely keep it up!!! 👍👍👍👍👍

I’m going to MIT for FREE! This is Awesome!❤️❤️❤️❤️❤️

Excellent and easy to grasp concepts. Need one update maybe, at 1:00:20 Bitcoin will use soon Schnorr signature instead of elliptic curve signatures

A nonce isn't a random number that is used once, it's just a number that is used once. In fact with EVM based chains the nonces of your transactions have to be in exact numerical order with no gaps or your transaction will never confirm. I you successfully send a transaction with nonce 1 and then try to send another with nonce 3 the second transaction will not be considered for confirmation until a transaction with nonce 2 is submitted.

Awesome show !

Damn we sittin here watching this for free not having to go in a debt with a student loan, while everyone in that room had to pay thousands just to hear this. Lmao

I’ve just spent an hour down the rabbit hole of blockchain like he said I would be in lecture 2 😂

The difficulty rating varies based on how much hash power is available to mine. The nonce value varies to accommodate increased or decreased hash power available to mine the next block. By adding or reducing the zeros in the nonce, the time to hash the next block precisely lands in 10 minute intervals, regardless of how much hash power is added or reduced.

Thanks for the content!

Blockchain is the evolution not only of economy but also for social life and sciences 1 of biggest fans

Thank you MIT courseware

i'm honestly just marveled that i made it to class 3 of an MIT course...

I stumbled on this last Night.. What an amazing insight..

Great engaging teacher!

thankyou for this video. I want to ask about technical presentation. How to switch between slide and presenter? is there an operator to operation this? thank you

Great content. Thank you!

Last September 2020 I bought 3 bitcoin at $9,000 when my friends told me I'm stupid for buying so high. Best decision ever.. 😂😂😂

One of the most valuable resources available on the internet about blockchain. Can anyone tell me which is the demo is he talking about?

I couldn’t believe my eyes when I see this course being taught by GG! Oh how the times have changed….

that first dude lol who read the book 5 years ago this is an inspiration if you realize hes at that class now , the implications haha

Cryptographic primitive - Used in communications & computations Hash functions Digital signatures Class 2 Review - Gensler mentions that blockchain isn’t necessarily the complete solution in the context of markets & money & that there are instances when an intermediary is necessary. But of course, there are cases when a decentralized solution will beat a centralized intermediary. - 10 key design features of Bitcoin: 1. Addresses 2. Hash functions 3. Nodes

Русскоязычные хомяки отмечаемся под этим комментом. Спасибо mit за уникальную возможность смотреть это из любой точки мира

28:32 interesting analogy Gary

I love this guy!!

Prof. Gary made a mistake with Base58's functionality, which is not designed to compress data, but to make binary data trasmitted over network easily and more visual friendly. The cons of Base58 is it makes data size bigger, not smaller.

The question at 49:45, the lecturer misunderstood/mis-answered (or was it me?) I think the point being made by the student is that: Assume some random set of transactions (and other bits) that produce a collusion with an existing hash in the blockchain. The probability that all of those transactions are also simultaneously valid is very low, and therefore the block would be rejected in many cases - thus reducing the number of possible collisions. Or put another way, it's not sufficient to find a set of transactions (and nonce etc) that produce the same hash, those transactions must also be completely valid for the starting ledger state.

Your mathematics is top tier babyyy

This is gold ❤️

Watching this in April 2024 16 days before the halving. BTC is is valued around $67,800

Wow, this course is addictive.

diffie hellman did pretty good privacy for email before bit coin think of the trap door hash function example add 2 primes even if u have the total u cannot recover the primes one is the public key one is the private key u need both to have validation. basically it is the one way trapdoor.

Does the word knots also transfer to the speed of a boat? Mph or kph are accurate but speed of a boat it surely Less accurate ?

Mr Gensler provided very detailed explanation about bitcoin and its cryptography.. could he be Satoshi Nakamoto or the part of the group??

The private key is the key for the seed

The time stamp is not what causes the difficulty adjustment its based on the last 2016 blocks

I’m confused if Larry is still there for the lecture or not

Students attending this class in 2018 who invested in BTC have seen their investment grow up to 10x to 20x(depending on the time in the year 2018) of the initial amount. Damn.

tank you for your lectures much appreciated. I dont know if i should be asking this question here but i just cannot find the answer anywhere. I have asked on forums but people give me generic answers. Being an academic my self i dont see anywhere else to turn to to ask. I have just started learning about crypto. I wanted to trade on the ADToken / BTC market and maybe some other similar ones. I am useing bittrex. I changed usd to btc, i started with 0.0005 btc. I then observed the market value of ADToken/BTC. at 0.00000002 btc. when the market value fell to 0.00000001 i went to buy but when i chedked the buy rate was 0.00000002 btc instead of the 0.00000001 btc market value showing on the graph. likewise when the value went up to 0.00000002 again, i notied when i went to sell, the sell value was only allowing me to sell at 0.00000001 . can anyone help. i cannot find the answer to this anywhere.

42:00 With the digibyte blockchain, you can download the entire blockchain quite easily. The exact mechanics Im not sure but its must more faster, scalable, and decentralized than any blockchain currently available.

This is a great lecture but I am confused by which order everything occurs. In order to mine the next block, don't the transactions from the current block have to be completed as indicated by the merkle root hash? Wouldn't that make for a lot of wasted time that miners could be mining? How can you be continuously guessing nonces if the transaction list is not fully determined?

Thanks MIT, MIT has made me think that I am now MIT, not at MIT...

Bravo! This is so great!!

The UTXO was a crucial piece he left out when trying to explain the public key impersonation question. Can anyone confirm this?

Could anybody tell which books were used in this course?

Love this! Thank you MIT!

Lovely, thanks

Great teacher. Thanks so much for this lecture Prof. Gary

I heard that the last Bitcoin Will not be mined before 2120…. Gerry saying 2040! Which one is correct?

Wow I could be in MIT. I did more readings then them :D and understood all. Great professor and it made me confident with myself. Thanks MIT, send me free stuff :DDD

If these people only knew it would have went up 10 times in 2021
