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??
A bit hazzy at the end
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?
you lost me at hello
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?
Thanks for the video.
Thank you for a good explanation. I can recommend this video. It definitely helped me understand the concept better.
what's the name of this guy? He's really good!
Super excited to talk About block chain
This video definitely helped me to understand the overview of blockchain more
Thanks for the explanation, I found it very helpful for someone who has no blockchain background. A less surprising ending like a conclusion could've made it even better.
Finally someone explaining it clearly in English not talking 20 miles in a minute.
GREAT video!! Thanks a lot for the clear explanation.
even though I comprehended the blockchain expl, the most amazing part of the last 11 minutes was the fact that the dude was writing inversely!
The video content was really good. I want a more comprehensive take on the idea of "Blockchain". The generation of the hashes. And the interlinkage too.
Great work thnks .
Learning same from Ednerds 👍
Thank you sir great presentation.
So digital currency? Nay
I understand the importance of privacy for a permissioned blockchain, but how does such a blockchain stop the retailer & the shipping company from seeing all information?
Haha wow. This guy can write backwards perfectly!!!!
I’m looking for a good video to help a friend of mine learn about blockchain . I’m not a noob by any means and I can tell you I had a hard time understanding what the hell you were talking about . After only 1 minute the average person would most likely abandon your explanation to never return again . You have done an injustice to the space and the progress we all hope to achieve . Terrible !
Hi Sai!Well done and explained!Thanks for sharing the information!
Is block chain a hardware, software or both?
Thanks for this video, gonna talk about it for a interview I have at IBM in a few weeks lol
makes sense until 4:40 then it all falls apart as an explanation. what is a client? what are transactions submitted to? to a node? where do nodes pick transactions from? is it one transation per block? now it looks like it's more than one in a block. what are you validating if you are still picking the next block to add? what does unlocking the position of the next block mean? that a node gets to pick? is the position a number, it sounds like there is more to it. It sounds to me you can only understand from this video if you already know.
This was beautifully explained. I would love a series on the topic of Blockchain. Thank you IBM for this.
This is utterly useless to me, I'm afraid. I stopped watching after a couple of minutes, totally lost in incomprehensible technicalities and terminology. Can you recommend an explanation that starts at a much lower level, please? Why use blockchain as opposed to other 'ordinary' methods? What are the advantages, if any, of using blockchain? What alleged problems does it avoid or solve? What use is it, if you need a degree in IT to understand it?
How will a permissioned blockchain reach a consensus.. if some part of it must be kept private only for a few people to be able to access that information?
Very well explained.
THAT MAN IS WRITING BACKWARDS or the video is simply mirrored
