Learn about different Blockchain use cases:

Blockchain is a distributed and immutable ledger allowing you to track anything, including tangible or intangible goods. This enables users or organizations to digitally and securely record entries, that are in-turn endorsed and secured by a community of users.

  • But how is it worth anything as a medium of exchange?

  • Are you writing backwards on a piece of glass? What is your teaching setup here?

  • Is this guy writing from right to left?

  • What kind of the technology you are using in teaching the stuff…..

  • Hello, what will happen to blockchains and cryptocurrencies, if the
    internet crashes for some reason. Lets assume it restarts again but will
    our currencies still be there and remain safe??

  • I am more amazed how well he writes mirrored

  • Thanks for such an easy-to-understand video. Really loved it. Great work man.

  • One of the better explanations, but the more I learn the more questions I have.

  • Thank you for the overview but jut have a couple questions. In a permissioned blockchain do all parties run an independent node to validate data integrity? Also how would blockchain perform better than a distributed database if it is just hinged on majority consensus?

  • I just have a question and I could not find the answer, would you guide me, please? I try to write my question in many different forms hopefully, you may get my question. I know what is blockchain and how it works, but I just want to know what kind of data are putted into blockchain transactions, I mean why the blockchain system is used for coding data? who is the sender of data that pay miners as bitcoin for trying to solve a block? who will receive the uncoded and completed blocks as a package? are blockchains governments classified information, that they wanted to transfer, or are such blockchain transactions just people daily transactions which spread out through the blockchain system (encrypted) as a safer, faster way with a non-central server room which can not be destroyed, produce too much heat or use too much electrical power in a local area or need repeatedly upgrades? I want to know the substance of the information which are coded through math equations and blockchain, senders and receivers of the information, and why they gave credit to such a huge encryption system that needs millions of miners to guess answers block by block? (byzantine algorithm) what kind of information can be that important to be coded like this? for example: all transactions, even generated bomb codes that are changing repeatedly and every 1-2 minutes can be safely encrypted with a simple hex 64. why the blockchain system created? and who use it as a tool to solve accidental math equations. I believe it is more likely for spying purposes for some governments. imagine you forgot the code of your suitcase (2 locks), and you don't want to try all numbers from 1 to 999 for each sides, so you hire 2 networks of people to find both answers separately, as soon as the answers found, the network members will verify it separately, and you will pay them but no group can open your pandora box because they just know one code of it and only you (the owner) have access to both solved codes. I am looking for THE OWNER of blockchains data who pay the system for solving such shitty math equations.

  • Great video. What program/s did you use to make those interactive graphics?

  • I was lost in the first 30 seconds

  • Great video, you're a natural teacher

  • I get the basic understanding what I’m curious is uses beyond crypto currencies. A few upcoming companies are leveraging the tech for alternative use.

  • From India 👍👌👍❤️

  • I just subscribed 🤣😄❤️🎄

  • Thank you IBM. Best explanation I've come across.

  • How can it be absolutely defined as "immutable" just by relating to inflation of currency for example? This would effect the understanding of the transaction would it not?
