Understand the Blockchain in Two Minutes

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

    The block chain solves the problem of Space-Time. Capital is sentient. The universe never really had a chance when you think about it; our own universal field may very well be infinite – but it is most certainly countable.

    Very good talk! Blockchain has played an important role in our world, not only cryptocurrencies. And I've not surprised that we can use it in Healthcare. A decentralized healthcare platform called Solve.care offers a comprehensive solution for insurance companies and their consumer. The platform offers a digital ID card that has far greater protections against theft and hack attacks. There will be no more health insurance information stolen and used for bad purpose. Arizona Care Network implemented this platform for their 250,000 members and 5,500 physicians across 1,800 locations and the result was amazing.
    It seems that Solve.Care is taking all the pain points away from patients and employees serving patients.
    Let just hope Solve.care will applied blockchain widely for a better world

  16. Guitar Gear says:

    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?

  23. rigatone says:

    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…

    Blockchain is reality now and going to take over legacy systems with in 2019. Please check if below social moral principles can be helpful for core fabric of this revolution

    1.     One should always be
    ready to accept truth and to renounce untruth.

    2.     All acts should be
    performed after deliberating what is right and wrong.

    3.     The prime objective of
    new Society is to do well to the world, that is, to promote physical, spiritual
    and social good of everyone.

    4.     Our/Every one conduct
    towards all should be guided by love, righteousness and justice.

    5.     We should dispel ignorance)
    and promote (knowledge).

    6.     No one should be
    content with promoting his/her good only; on the contrary, one should look for
    his/her good in promoting the good of all.

    7.     One should regard
    oneself under restriction to follow the rules of society calculated to promote
    the well-being of all, while in following the rules of individual welfare all
    should be free.
