Do not use the camera crew again for Devcon 3. These people did not know how to film/direct a keynote. many slides were missed due to the director being asleep at the wheel and not switching cameras. The pan-the-audience shots are useful for an arena rock tour, not a developers conference. Find whoever is running the Chaos Communication Congress' setup, and pay them to run it. they'd do a much better job than these guys.

[@mal3xia]

Yea...I want to see the slides to get more context on what hes talking about.

[@Sibisi]

"Director" is either lazy to plan or plain stupid....ot both!

[@dankmheems290]

Actually it's the producer's job when it comes to newsy/conference type stuff. But yeh he was asleep at the wheel.

[@dankmheems290]

I actually believe you for half a second and felt bad then went, wait a minute...

[@nawaal4452]

Bob8199 lmao! 😂

[@andreaspizsa]

It frustrates me that the video shows the speaker and fly-overs of the audience, and at the same time leaves out entire slides. 4:10 is one example, and it goes on like this throughout the video. That's disappointing, because Vitalik is a great speaker and his slides are needed to understand what he is referring to.

[@EthereumFoundation]

Slides are located at ethereumfoundation.org/devcon/?session=2-ethereum-in-25-minutes

[@_jikkujose]

It should have been embedded in the video in such a way that the slides are always seen. Would have helped much.

[@subjectivereality834]

Agreed, would be great if someone took the time to edit them in.

[@tomwojcik]

I thought that I'm the only one who noticed that. A TED style would be way better, if you know what I mean.

[@vierachstevandezevendeorde5211]

I agree and the sound is annoying too. Intro music to loud and vitalik volume is to low because I use my screen build in speakers have to switch to headphones. Food for thought. But keep up the great work Ethereum !!

[@chorgin]

05:37 Prof Of Server - Best POS His jokes are so next level that no one laughs

[@samparko723]

would you be so kind to elaborate? i didnt get it

[@ZweiBein]

i lmfao hahaha

[@enkrypt3d]

POS = piece of shit

[@ConradTTC]

The entire goal of the Blockchain is to delegate trust to a decentralized peer-to-peer system. This is done using either Proof of Work or Proof of Stake. Proof of Server is how you would call the "old" trust system, in which one entity controls the validity of the transation. The opposite of Blockchain.

[@justraze9525]

I've been educating people on crypto just so I have someone to eventually share this joke with.

[@xyhmo]

3:00 am, Vitalik is born. 3:01 am, Vitalik: LETS DO THIS THING (pull out a computer, starts coding)

[@c0unterph0bia]

I love how the slides come up, and then the camera pans AWAY from them! Pan towards them, what kind of company is filming this? I feel like I'm at a church sermon or something.

[@nairbyad7188]

they must be used to entertainers, not educators

[@hhbuerger]

To the organizers: PLEASE, for the next conference get headsets for your speakers!

[@aml6400]

Do you see that young man on stage? If you can own 0.0000001% of this guys creation, you will die an extremely wealthy person. Mark my words.

[@kevintourdeaumad1666]

you are right buddy....and by the time to die medicine would advance so much that you can chose to not die at all and being so wealthy you can afford it :D

[@ezaeza3107]

this project is very good.I am very happy working on this project.I hope those of you who have done this project have done well.

[@EricLeonor]

the constant camera panning is frustrating. I want to see and participate in what the speaker is talking about via the slides but the camera either zooms in to his face or pans across the audience, both of which i have no interest in. i am interested in whats written whilst the speaker is talking. and no, i dont want to view the slides separately.

[@kursionable]

Hi, is it possible to have the slides ?

[@ApolloLax]

Link for slides does not work for me, any ideas?

[@raysonkong]

anyone got the slides? it is not on the server !! thanks!

[@maximilianocorrea3705]

Thanks for creating the video. Can you help me with a question? Can Ethereum Smart Contract be used to receive and send bitcoins?

[@dankmheems290]

I bought 200 USD of ether when it was at 17 each. Wish I had put waaaay more in.

Presentation slides not visible!

[@srsundar33]

amazing explanation

[@pedrodfg]

It would be great to see the slides too

[@MrPaperchips]

I think everyone can agree that this video would be more useful if the video portion was replaced with the slideshow, timed with the audio. I tried following the link to download the slideshow to keep up, but that link was dead. This really needs to be fixed.

Best tutorial ive evr seen bro ur d best!!!!!

[@tombranson9341]

I am a CS grad student and am getting a better understanding of the underlying technology behind Blockchain (BC) and its potential. But, I am sill kind of skeptical on bitcoin, ethereum, etc.. If we look at BC as a new technology to track a financial asset, say an new IPO on the stock market and this can show a chain of ownership, whether someone is attempting to manipulate it by insider trading, etc.. I am all for it. Also, another use case is about ownership of something.. say a hard consumer good like a car, washing machine, etc... those could be embedded with a Blockchain from manufacture to buyer and all the life of the product... all VIN, INSURANCE, TITLE, OWNERSHIP, MAINTENANCE is encoded every step of the way and all someone has to do is look at a app and it shows everything about the car and how it was maintained.. that is very valuable to a seller and buyer in the secondary market. I still don't fully understand the all the broad use cases yet for Etherium smart contracts with the limited knowledge that I possess on the subject, but what I see as a skeptic to the underlying broad scope of things are: who or what is in actual control of the money supply? but beyond that... when the gas and other 'fees' part was explained... it dawned on me.. this seems to be more about nicking fees and who controls the fees or "tolls" - in the business world -... who is the gatekeeper? and how big is the moat? My skeptical self instructs me that this is as much as who will get the 'fees' from uses, than about creating a new model of financial commerce and wrapping it in a utopian bow. Don't get me wrong... as a programmer, and all around nosey person... I like what I see, but still kind of holding it at half arm's length away until I 'gets' my head wrapped around this. Valery: improve your speech patterns.. stop with the 's' at the end of each verb... it's not only annoying.. but wrong and takes away from the genius that you are.. further, when and if this goes more mainstream, folks are more likely to take you seriously.

[@charlesgoldt7943]

I would love to hear an update on your view of Ethereum and Blockchain in general now, a year later. I know this is very random, but i too am nosey :)

[@oknoobcom]

It's like some live music clips, where they show a close up of the drummer, when the guitar player is playing an awesome solo. Wtf people. Show the slides!!

The price of this coin will double before Halloween. I consider this the best bet for a future holding. If tomorrow my father came to me and said son, manage my money. I'd put 100 percent of it into eth. Food for thought: 200,000 total developers working within the Eth sphere.

[@djBC10000]

for some reason watching this video at 1.5x speed made it more understandable than watching it at 1x speed.

[@rajaatsethi7448]

At 15:16 he talks about the halting problem, if this problem is not solved, the transaction fee will go higher and no will want to use it anymore.

[@heraldo623]

If the gas is over the whole transaction is rolled back. No changes are made on the blockchain.

How did the audience grasp all this without pen and paper? :o

You could avoid the mic issues altogether with a snap on pack style... holding on to that mic for 25 minutes is just redic

[@tickledropstop]

Advice to the camera man. Keep the camera at the slides, not the presenter.

[@cryptobradley2006]

Vitalik say you pic 5 of your buddies how long would it take you guys to break the Ethereum model you have created?

[@andresgonzalezaragon5689]

The presentation is not available anymore

[@semenpavlov5778]

What will you tell o to the TokenGo platform? The project is perspective, the command actively advances a new functionality, new counters are entered. The personal office for bounist's convenient, did not see it still on one platform. Developers embody the relevant ideas in life. I think to this project it is worth giving fixed attention.

[@charliekp6534]

How can i actually learn about ethereum and cryptocurrencies? Dude's going on about blockchains like i know what that is? Anyone know where i can start off (i really know nothing about it) and then graduate to become knowledgeable on this stuff? Thanks

[@Felipe-zl1rj]

Fuck. I've watched a thounsand videos already, and it's safe to say that I will never understand what ethereum is. #frustration

[@jllarivee60]

Felipe its basically a platform you can write code to. So, for example, you could write code that says -> if Bill pays Margaret x amount of Ethereum then send Bill y amount of ethereum. This is a contract that can be written to the ethereum platform.

[@maesitos]

t's just one computer running in multiple machines that stores the value of 'ether' in each account and a list of key, value information. Think of the state as the current status of your computer now, for example the exact size of your browser's window at this right moment and think of the blockchain as the software siting on your hard drive when your computer is turned off. Still in my opinion everything would need more clarity. Things like the name 'Contract Accounts' is very unfortunate.

[@alansdad4613]

It's basically an operating system on which developers can create programs on. Bitcoin is blockchain for currency but, Ethereum is blockchain for EVERYTHING, on top of which developers can build programs/functions.

Is Ethereum also a currency?

[@londonspade5896]

Ethereum numbers have no limit, correct? This like a fiat currency in that way, surely the value will go down as a result? I'm confused as to why it's a good investment long term.

[@rumfordc]

ether is distributed algorithmically, according to a curved rate of inflation. New ether will always be added but less and less over time and nothing can change it. fiat currency has no such algorithmically enforced limit. In times of great inflation ether would rise in value relative to fiat.

[@londonspade5896]

Ah thanks

[@rumfordc]

on a side note, that's pretty much how all cryptocurrencies work but the purpose of Ethereum isn't just to be another cryptocurrency its a Decentralized Consensus Network in other words a framework for creating applications that can't be stopped, censored or updated once started and are fully public to the network. The success of Ethereum will depend on the success of these applications, so that's most investments should take into account i think.
