This video is brilliant. Talking about stuff that is happening today like Robinhood selling data to Citadel and Google/Facebook regulations which are hot topics today. I am hoping Mr Gensler as SEC chairman does the right things for Crypto and Blockchain. I hope we get real time settlement for stocks under his watch so that Robinhood does not get margin called.
Most useful part of this class for me: “The word settlement means to finally change the data in a ledger, and that we’re not gonna come back to it. It’s done. It’s final. If we’re moving something of value, and the value could be grapes, the value could be diamonds, the value can be real estate, the value can be money, but if we’re moving something of value and storing it on a ledger, it’s more adaptable to blockchain. If you’re doing some database that has nothing to do with things of value and ledger, you don’t need final immutable settlement, I would contend you have less reason to use any of this blockchain stuff… And another thing that blockchains help with is they lower the cost of reconciling multiple databases.”
1:17 Gary “I was at his wedding, and he’s getting married again next week. After class you can all ask him about Fidelity” 😐 Gary really should have said those sentences apart from each other
38:29 Gary in 2018 : I would say the investor protection side (blockchain), we’re at the early stages and it’s going to take, in most jurisdictions, another three years. Gary in 2021 : The Senate has confirmed Gary Gensler as SEC chairman in a 53-45 vote. Nice.
1:10:42 - The turning point for Walmart in its battle against K-Mart during their prime, was Walmarts initiative to adopt the satellite based technology for their suppliers. K-Mart was still operating on pen & paper for most of their operations. Walmart is pretty good at adapting to the times and using it to their advantage. I would argue that blockchain technology to be much more efficient to satellite based tech in all ways. They see that, hence their transition.
What a fantastic experience. I am a full stack student blockchain developer. I have limited resources at age 80 and going strong. It’s never too late to learn. Do you have any grants for inventiveness?
Towards the end of the video, you were talking about tracking foods and logistics. You need to take a good look at VeChain/VET who has already put together a program with Price Waterhouse Cooper and Wal-mart China. They have already passed with flying colors, the first stage of testing with Walmart-China and moving on the next and much larger scale of testing the VeChain logistics project with Walmart China. VeChain’s technology basically follows each product from the farm to the processors to the distributors to the retail stores. With all the covid problems, it protect all combined where the products have been to even the temperatures of the environments. VeChain is putting together more customers and partners and now joins Chinese alliance with Walmart, Starbucks and McDonald. Per Jake Simmons, by September 18, 2020 VeChain has joined the China Animal Health And Food Safety Alliance, sponsored by the Ministry of Agriculture of the People's Republic of China, as a council member.
The students discussing the potential use of blockchain for real estate titles (50:00) don't seem to be aware of M.E.R.S. (Mortgage Electronic Registry System). While not actually titles, mortgages, too, need to be registered at the local government records; at least they used to until MERS. Since most mortgages are traded in the secondary market, the mortgage brokers considered it too cumbersome to record those transfers at local records agencies and built their own system. It became embroiled in court cases around the country and resulted in a foreclosure defense known as "Show Me The Note". The mortgage brokers would have been better served by recording the transfers on a public blockchain than they were by their permission, centralized system. Today, the entire real estate sector is relying on MERS to track who is owed the mortgage payments. Any mistake by MERS means the wrong entity got paid while the legitimate lender might still have a claim. MERS is quite a mess.
Scalability and Security I can see, but Decentralization is difficult when the currency is pre-mined with 16.99% going to the developers. And because it is proof of stake, those who want to take over the network (corporate/state actors) simply have to buy a lot of the currency. With proof-of-work, energy-intensive as it is, an intermediary (miners) exists between corporate/state actors and influence over the protocols. I am still wrapping my head around the properties of consensus mechanisms but I think as of now a proof-of-work system is needed for maximized decentralization. Otherwise in my opinion it will be the weakest of the trilemma.
I am having a great audio problem understanding all international dialects. Is it possible to have the presenter paraphrase in English what is being spoken by someone in the audience with a non English dialect?
We recommend you turn on captioning. Almost all of our videos are captioned. There are also transcripts available on MIT OpenCourseWare at: ocw.mit.edu/15-S12F18. Best wishes on your studies!
30:00 You have some policing on it… But there isn’t any policing on centralized front running… None. There are no penalties for Market Makers or Hedge Funds, or if there are they are negligible and the cost of doing business. We need penalties that fit the crime and jail for those who commit them. 33:02 Time-stamping and order books.
I think it is wrong to say a "hash" is compressing data. Because that would mean, I could decompress the hash and get the same data out of it. That's not possible. So a hash is more like an encrypted summary of the content it hashes. And I can make sure, that if I have the same original content, and hash it with the same Algorithm, the hash will be identical and therefore the exact same data, which is the proof that it's actually the same content and wasn't changed.
I feel like Bitcoin is permissioned. Doesn't the tx fee serve to entice the miner to grant you permission to be included in their block? A zero fee transaction might never be processed. If I require zero permission, why do I require a fee? Also, can't miners decide based on any other parameter they choose? One miner might not care about fees at all and instead simply requires that anyone in his block ask permission first. What am I missing here?
@@HugosLeung Was your post intended as a personal attack? It's very rude to post "go back to bitcoin 101" when in fact it is you who is incapable of articulating even a single sentence on the subject. What about my post indicates lack of knowledge? I actually arrived at my question after reviewing the functions included in Satoshi's original source code. I honestly don't think transactions can be processed without the permission of miners. But like I said, I've got to be missing something right?
Not a personal attack. It is permissionless bc the miner solving the PoW gets to add the block and that can be anybody. It is not limited as it would a permissions system. This is what I mean by going to the fundamentals. As for what gets entered into the block, that is not part of the definition of permission. It would have to do with how transactions get grabbed from the database of queued transactions.
The transaction statistics are misleading. #Bitcoin has batched transactions and layer 2. So it depends how you want to slice this but #Bitcoin is handling more transactions than what people can imagine!
Let’s all trust the brilliant British woman famous for credit default swap. Human greed truly has no shame or limits. We can forgive Robert Oppenheimer but not sure what kind of mental gymnastics we have to do here.

In terms of the trilemma, bitcoin loses on scalability but xrp loses on decentralization. I would argue decentralization is the most important of the three. I don't see governments being okay with xrp when they can just design their own centralized digital currencies.

i'm sorry to give you a thumbs down, but i don't know what else to do. this video keeps playing despite my attempts to block it. i ve seen it once and that was enough. i wasn't that interested in the first place. stop playing this in my feed. what's the point of giving useres the option to tell you we're not interested in seeing content if you're just going to show said content more often after the request was made. pretty sure i blocked this channel last time it came up in my feed..
I am amazed by how he is able to summarize every question asked so beautifully and concise.
It's like he understands the question even better than the person who asked it lol
And now he can't even decide if he wanna go after Bitcoin or not 😂
Hugo's investor protection question @28:00 even references robinhood specifically. Brilliant.
Blew my MIND
yea it's wild to see how much of the stuff discussed here played out
This class was in 2018 btw, insane how far ahead of the curve these guys were
This is how humans can create a better future, share knowledge. Thank you MIT.
I feel like I am back in college, it is great. I am slowly getting these theories, but I have to say I am so happy I am not being graded.
This is the way !
C-
These MIT videos are gold. Thank you so much for uploading these for the general public!
100% with you. I feel so blessed watching these

The broccoli analogy was great LOL. And as mentioned by a few others, Hugo's question referencing Robinhood was spot on. Bravo.
code, blockchain and ledgers .... changing they way we keep lists and accounts ..... incredible !
"He's having his second wedding coming up, you can all grill him about fidelity" bahahahaha 😂
boy that robinhood question at minute 28 was spot on 😎
Dark pool?
What a lecture! So far this was the most exciting part of the course. Im excited to the next classes.

Yep, exactly what I was thinking. VET is already doing this
Vet to the moon 🌙
Nice video and the concluding advice.. thanks prof. Gensler
Noticed something weird: Gensler pronounces "susceptible" as "sup-sceptible" twice, once at 1:07:10 and the other earlier.
Thank you MIT. This is highly appreciated!
Absolutely well done and definitely keep it up!!! 👍👍👍👍👍
We will plan on looking at Corda.
Love explanation of front running!
Thank you for sharing this knowledge
23:57 I like how this was explained.
