Dr Andreas me perdoe e algo fiz centros supletivo s com problema de saúde deste criança são estudos………se formar desocupado e algo sério livros dor cabeça ética segurança saúde costas peso desobediência e perto portão rua como chá ? Pede pedra sopa receita.? Hoje como pessoas com perdas de espaço aceita café?
This is awesome.
Andreas is a true genius! One can easily detect that, not from his deep knowledge on the subject, but from the humility with which she shares it with others! Standing applause!
So do the Forks keep us safe in the long run

Watching this in 2019 gives me a real feeling of how tech evolves! This was recorded when BITCOIN CASH was still a theory without a name yet, we have two bitcoin cash now! lightning network was still alive only in theory, we have payment channels funded with 1 BTC currently and still growing! Truly bullish on the future of crypto!!?
Thank you…anto…
Don't know what the guy put in his sha256 function, but it was not that phrase. A8D19 is not what I'm getting… 🙂

Thank you Andreas for such a clear explanation!
@aantonop don't you think that consensus rule about the longest chain leads to mining concentration in a certain region ? I appreciate your feedback
After reading Forbs and Verge article I have some doubt what Consensys and Joe Lubin doing with crypto future

26:36 Who sets the validation rules? I disagree with your answer here Andreas! I think the answer is simply 'consensus' (and all that that implies). Discussing reference implementation and core implementation may be technically correct, but it's conceptually wrong. kthxbi
Consensys is on the way down according to Verge article, Forbes article declared Joe Lubin incompetent
https://www.theblockcrypto.com/tiny/the-verge-consensys-could-be-laying-off-as-many-as-50-60-of-its-employees/
is bitcoin could be forked into post quantum cryptography
what do you think of hashgraph?
those guy in first row so bored. how it even possible when you attending absolutely fascinating lecture. I'm dreaming to learn this those days.
How about kris kringle combine b-cash and satoshi Bitcoin to create peer to peer kringle cash ?
Best Tube ever!!! I learned so much
Andreas, you have such a fantastic way of explaining things in the most clear, simple, precise, and non-arrogant way. People love you because you are clearly a genius but you don't make your listeners feel dumb. Bravo sir.
just for people who wonder, the guy in the room gave the sha-1 hash, not the sha256 hash, he run the command wrong (i guess using mac, where default is sha-1 from the shasum command)
If you are in search for some good technical explanations about Bitcoin, this video is a must watch. Hats off to Andreas !!
blockchain seems intelligent but it is not the future
what a nightmare of doing things
it is not good
it is like coal
we already have better systems
Great talk and finally someone that can explain the details.
Everyone in this room is now rich or stupid!

Best video on POW on YouTube … Best work by Andreas
Absolutely dynamite talk, at this point these more technical ones are the ones I enjoy the most.
and as i understood if you're not moving your coins during these forks, your funds are safu) right?
so all the race are for the Zeros. or any particular line of same numbers in the begining of hash. could it be a line of "1111jhdihwbvih…"? or"…ijwdhgviwfh000000000"?. I'm wondering what the reason behind chosing "zeros before hash" as a main cryteria?? is it the hadrest combination to find somehow?
At the time of race condition how the reward system work?
Interesting extreme bi-forkation event at 54:40
what if after fork also both forks generate one more block, then what happen to transactions in orphan Block?
How a node agrees to particular nonce? and Who exactly maintains this nonce value.
Brilliant explanation. Great work Sir.
