16:03 I'm so smart! I answered that before everyone! lol
oh look the guy who wants to ban crypto
Gary Gensler is Satoshi Nakamoto and he's just trolling everybody every time he asks. 1:10:30
Gary Gensler? Is that you ?
Very fascinating class! Thank you
Honestly. Thank you. I'm learning a lot and I've been messing with bitcoin here and there for years. Gensler 2024.
Craig Steven Wright aka Satoshi.
Thank me later.
Dr craig wright is satoshi nakamoto
Thank God for these classes God bless MIT if I had to pay for these courses I wouldn’t be able to eat
ELON MUSK IS SATOSHI NAKAMOTO!!!!!!!!!!!!!!!!!!!!!
One would surmise that during the conversion from text to hash the 'mechanism' of conversion makes the hash useless. My understanding is the conversion is similar to compiling a program. If you have the 'mechanism' of the compiler, you automatically know the character of the machine language coming out on the other end.
Amazing how difficult it is to imagine that Nakamoto is not a celebrity but some genius who maintained his identity anonymous.
First table had the semi-correct answer. Multiple people. Hal Finney & David Kleinman. Both of these gentlemen are deceased.
Are not the unspent transactions inputs? how can they be outputs?
students reveal!
sheesh
WOW MATTHEW do your readings man….very dissappointed
I've really enjoyed Gary Gensler's teaching style. Thank you MIT for allowing us (the world) to enjoy these classes on youtube. #blockchain #blockchainknowledge #bitcoin #learnbitcoin #learnblockchain #enjoylife
?✨? THANKYOU
Very professional and informative ⭐⭐⭐⭐⭐
Oh my God. I've never been so excited to learn. Love this course.!!!!

If terminator came back in time he'd hunt down Satoshi Nakamoto #BTC
Thank you very much ?
YT crowd here, who's your pick for Satoshi Nakamoto?
Where is the lecture? he's just discussing questions over and over from the public? He barely touched the theory
broccoli soup is fantastic
DARPA has invented Bitcoin…
what a nice gentlemen Prof. Gary ..My sincere respect to his patience and sensitivity !
He knows who Satoshi is.
At 41:46, Transaction sent to Hash of Bitcoin Address – Pay-to-PubKeyHash is 81%. But isn't a bitcoin address already a hash of the public-key? why would you hash that again?
Plot twist, he is Satoshi Nakamoto
so nobody picked Adam Back or Paul Leroux.
Prof, Gary comes across as a very decent man. If only I had a professor like him when I was in college. MIT and those students are lucky to have him teach this class.
What happens if the NONCE cannot be found within a 10-minute window?
Is Bitcoin based on the $USD?
How do I convert Bitcoin Yen to Bitcoin $USD?
How are exchange rates handled?
I love broccoli!
Hash function
it's Craig.
Whoever picked Gary Gensler to be the SEC Chair sure did the right thing. He is exactly the sort of person you need in that role, at this time…
Craig wright is satoshi nakamoto…only morons don't know that in 2021… nice my comment is censored. F utube…its garbage. Can't wait for LIFE AFTER GOOGLE
Craig Wright
Thank you thoroughly explaining hashing
Prof Gary is a really great lecturer, very engaging, and the topic is fascinating.
when PhD?
1:02:00 The whole consensus mechanism reminds me of notary offices. Nodes are working like a network of notary offices notarizing copies of documents and getting a fee (bitcoin and later what?) for the work done. Then they are collectively bookkeeping the record of the all notarized documents (transactions and balances?) to date. They are in a sense vouching that the transaction indeek took place.
Who is then managing the balance in each wallet/private address? The bitcoin script itself? It should be referring to the block number where a certain account/wallet has last been updated for balance to read the (most recent) balance from the record, not necessarily always but whenever a new transaction is going to take place.
43:19 Holochain, Dag will be the future after blockchain
The last statement Gary at the end of this lecture made me think he might know who Satoshi is.
1rst of all many thanks to MIT for sharing this unique empowering Blockchain courses,my respects and admiration to Professor Gensler.
