When you vote have you ever wondered
whether your ballot is actually counted? If you meet someone online how do you
know they’re who they say they are? When you buy coffee that’s labeled fair trade what makes you so certain of its origin? To be sure really sure about any of
those questions you need a system where records could be stored, facts can be
verified by anyone, and security is guaranteed. That way no one could cheat
the system by editing records because everyone using the system would be
watching. Systems like this are on the horizon and the software that powers
them it’s called a blockchain. Blockchains store information across the
network of personal computers, making them not just decentralized but distributed. This means no central company or person owns the system, yet everyone can use it
and help run it. This is important because it means it’s difficult for any
one person to take down the network or corrupt it. The people who run the system
use their computer to hold bundles of records submitted by others, known as
“blocks,” in a chronological chain. The blockchain uses a form of math called cryptography to ensure that records can’t be counterfeited or changed by anyone
else. You’ve probably heard of the blockchain’s first killer app: a form of digital cash called Bitcoin that you can send to anyone, even a complete stranger. Bitcoin is different from credit cards, PayPal, or other ways to send money because there isn’t a bank or financial middlemen involved. Instead, people from all over the world
help move the digital money by validating others’ Bitcoin transactions
with their personal computers, earning a small fee in the process.
Bitcoin uses the blockchain by tracking records of ownership over the
digital cash, so only one person can be the owner at a time and the cash can’t
be spent twice, like counterfeit money in the physical world can. But bitcoin is
just the beginning for blockchains. In the future, blockchains that manage and verify online data could enable us to launch companies that are entirely run
by algorithms, make self-driving cars safer, help us protect our online
identities, and even track the billions of devices on the Internet of Things.
These innovations will change our lives forever and it’s all just beginning. To

  1. Read about how to architect a blockchain application.

  2. This cyber hackers platform its so wonderful i benefited alot from the bit coin mining and investment its so real and legit i gained about 0.1 bit coin a day if you in need of help for mining and investing bit coin you can send him a DM on instagram @internetkingssolutions_

  3. I get the chilling impression that nobody really knows the value nor future of cryptocurrency and a blockchain 'controlled' financial society. WOW!!!!

  4. And when vast proportions of country's economies are tied into bitcoin and other cryptocurrencies what may have started out as an altruistic endeavor for the good of the world will all unravel and the taxpayers will be told that cryptocurrency is too big too fail. Where there is money to be made by cheating the system you're up against the Wallstreet banksters who have hired armies of lawyers and tech savvy personnel to write algorithms that have figured out how to exploit loopholes and weaknesses. Just as it did in what lead up to the financial crash of 2008 with their exotic financial instruments such as credit default swaps and hedge fund managers betting against subprime mortgages. I realize that there is supposed to be concerned citizens overseeing that this is kept honest but where there are people there is corruption. I'm concerned about how cryptocurrency will be kept above board and the security aspects of it. In the end of any transaction that occurs won't it have to be backed by an actual currency anyway to settle the payment from buyer to seller?

  5. Power goes done like it did during Sandy in New York and block chain becomes 100% USELESS. I would never want it for a substitute of cash. Paper and coins work fine they just need a backing standard that is a basket of useable goods.

  6. Has anyone heard of the HYBSE joint venture ? https://cointelegraph.com/press-releases/mindex-gmex-group-and-hybse-join-forces-to-launch-the-first-blockchain-securities-exchange-in-mauritius

  7. I suspect that early adoption means you can potentially make money out of it, much the same way as buying bitcoin early made a healthy profit up until 2 years ago, before it's value decreased. In future, the concept of blockchain may not be as useful (I know nothing of quantum computing but I'm going to look it up!) but for now, it's still such a new and unknown 'thing' that many businesses are keen to monetize it or try it out…

  8. since BTC is low now is better I continue earning BTC with the help of Vosk Coin miners,they are actually fast as I heard and confirmed.

  9. Brief book about blockchain

    BLOCKCHAIN TECHNOLOGY FOR BEGINNERS https://www.amazon.com/dp/B07KNR58M9/ref=cm_sw_r_cp_apa_7xA9BbP18EZDW

  10. still can't understand what blockchain is but thanks for the effort. Anyway, check this app called benepit.io you can get rewards just by making your regular phone calls or watching ads.

  11. If we have companies entirely run by algorithms (1:50) is that how they'll manage lawsuits regarding self-driving cars? Will people end up suing companies that are effectively extensions of a computer algorithm (people suing computers)?

  12. Who input the first data who is winner? How to confirm first data input is true? I said you land is my, so its mine? Or your company decides who said is true?

  13. What that means in English is that one person will collect the taxes instead of the individuals. hmmmm….. where have I heard of this before?

  14. “If you meet someone online how do you know they are who they say they are?” Contradictory sentence: “You’ll be able to protect your identity online.”

  15. You can also invest in real blockchain projects, like this one that has multiple use cases to lessen an investor's risk.

  16. Why is there a fee with Bitcoin transactions? Who is the centralized institution that gets the bitcoins' fee money?

  17. With Block Chain THEY will be able to track How much urine you dispense THINK ! !
    Every purchase, Every device, Every location, " THEY WILL KNOW ". THINK ! !

    Freedom is not free. Land of the FREE, Because of the BRAVE.

  18. Bitcoin trade has always been a mystery to me, until I met Mr Richard Scottfield through a client of mine and I traded bitcoin worth 2500$ with him, after a period of 7days, I received a profit of 8000$. Sincerely at first I was skeptical about it but am glad I did trade with him

  19. Nice way to easily explain the system to beginners! Some totally fresh view, we would like to share with you guys out newest app “Cryptalk”, join crypto world with us!

  20. Understand that if you buy nothing and hope to get something for that you will find you're left with What you paid for. Nothing.
    "Get your shit together, and buy silver!" Chris Duane

  21. Its a scam to get your money. Don't buy into it. Its called "the fed and state money laundering ponzi scheme because all that printed money from out of thin air to keep a failing system afloat needs somewhere to go)

  23. So if information about me (or you) is incorrect, its impossible to change because its in 1000's of locations around the world at the same time and they won't allow anyone to change it, sounds like blockchain is very dangerous to me.

  24. When is our ability to explain technology in simple terms going to catch up with the geeks that come up with this stuff? I swear there are aliens amongst us whose brains work on a different level these days

  25. why is it those that understand blockchain always fail to explain it to those that don't…..pisses me off

  47. The purpose of this piece is to introduce the concept of bitcoin mining. When I was home for holidays, I had family and friends that haven't heard of the word "bitcoin". This space is highly volatile and complex. You have to be open minded and have willingness to learn and teach yourself a completely new skill to see return in this. To make it clear I'm no expert. I just don't want you to miss out the opportunity I'm privileged to have. I'm planning to follow up videos on YouTube as a step by step to get into space. But again, do your own research or you can contact the lady behind my success as a trader, Princess Mai Fujimoto (The Bitcoin Princess from Japan) she makes use of bots in her mining analysis, she equally earns bitcoin for miners and give them the latest techniques on how to mine bitcoin. Reach her by [email protected] for her assistance as well as binary and forex trading. I have been privileged to be blessed by her abundant trade knowledge.

  48. This professional lady hacker also did it for me, it work through her services.via +1 62 63 86 31 55 she founded me 3.0997 btc to my wallet

  49. I'm absolutely impressed working with +1(626)386-3155 she just fund me 10.0887bitcoin to my blockchain account, with no failure
