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 video is a great resource for people who are looking for a way to deepen their knowledge in blockchain technology and go through everything from smart contracts to permissioned and permissionless blockchains.
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. Thanks nonetheless.
Amazing well described this complex topic , especially the difference between public and "private" block chains has been pointed out very well. I was always asking myself, how block chain wants to become so successful in a world where transparancy is often requested but not implemented....now I know. Thank you!
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?
Probably a correction here: "shipper" should be corrected as "carrier", this is because the "manufacturer" is the "shipper" and the shipping company is the "carrier".
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.
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?
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?
A permissioned blockchain is a misnomer of blockchain. If it is permissioned, it is not blockchain. It already exists and existed before web 1.0. All of the features exist and are in use today and have been in use for the last 40+ years before the internet, when large corporations had their intranet, and before then as hard-paper copy audit trails. Part of the definition of blockchain is that it is permissionless. You had your Freudian slip when you first misspelled "Privacy".
The point that is buried is this: why a blockchain is needed? For example, what role does a blockchain play in determining if all the condition for a shipment are met? Isn't this just a simply check?
Hi speng01! The blockchain is a single source of truth that is capable of managing itself for multiple entities. In my example, it was across multiple companies who each need a different scope of data stored in the same chain. This is inherently more advantageous and secure than each company keeping its own records. Thanks for watching, San
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?
Data on the blockchain is encrypted, and only decrypted by users with the right permissions. User management and access control is a core part of permissioned blockchains.
Hi Daniel!...no witchcraft at work I promise 😀 Here's a post we wrote to explain how these videos are created. th-cam.com/channels/KWaEZ-_VweaEx1j62do_vQ.htmlcommunity?lb=Ugzf5SL_yh9NglCJzgF4AaABCQ Let us know if you have any more questions and thanks for visiting.
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.
Hi Banonie! The Blockchain is distributed across all of its peers - meaning you and I could run a public permissionless blockchain on our local machines! So what if you and I both wanted to add our own transaction to the chain? To avoid our two blockchains becoming forked (no longer matching), a race (complex problem) is implemented. The first one of us to finish the race gets to add the transaction - let’s say that I won. You would then verify that I really did finish the race first, and also validate the transaction that I added. Thank you for watching! -Sai
Hasan, it seems you would have to TRUST an entity to give you valid block data. Bitcoin solves this by everyone running a full node (no mining needed for this).
So why would a business use blockchain vs a normal system? Isn't the whole point of all this to allow parties who don't trust each other to perform transactions?

The Market have been suffering over the past month, with all the three indexes recording losses in recent weeks. My $400,000 portfolio is down by approximately 20%, any recommendations to scale up my returns before retirement will be highly appreciated.
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?
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 !
One of the better explanations, but the more I learn the more questions I have.
that means you're learning well
yep, you are progressing to learn more
Congratulations, you have discovered the Dunning Kruger effect. Its a long road ahead 👍
True 😂 then the more i confused
Thats what they want you to. Its a scam at world wide scale
Who decides of the "members" of the chain ? What hardware ? What programs ? How come nobody ever talk about that ?
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.

This was beautifully explained. I would love a series on the topic of Blockchain. Thank you IBM for this.

I am more amazed how well he writes mirrored
yeah like wow
Bro.... the video is mirrored :D :D I guess
Me, too...! I'm like... is he writing backwards?! LOL🤣
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!
Fahad Shaikh I thought the same thing but it may be a mirror filter on the video. He is writing with his left which is pretty uncommon.
Hey guys! We actually wrote this post to explain the technique: ibm.co/3b9C7i4 😃 Thank you for watching the video.
@@IBMTechnology actually I didn't understand half may be I am beginner. Still I have one doubt why there is no course for blockchain
This video definitely helped me to understand the overview of blockchain more
Finally someone explaining it clearly in English not talking 20 miles in a minute.

Thanks nonetheless.

Watching your channel motivates me to improve. Just launched a channel and sharing my journey so far.
Can you please explain how the level of data storage required for each transaction may be increased due to this method?
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?
Did you make the video readable by mirroring it vertically?
If not, this guy is brilliant!
A permissioned blockchain is just a database!
Sure. Much like a smartphone is just a CB radio, right?
no
Thought so too
Thank you IBM. Best explanation I've come across.
Probably a correction here: "shipper" should be corrected as "carrier", this is because the "manufacturer" is the "shipper" and the shipping company is the "carrier".
2:52 but computing hashes is really quick, right? It's just guessing them that's tricky

What kind of the technology you are using in teaching the stuff.....
Thanks for such an easy-to-understand video. Really loved it. Great work man.
great explanation, seriously dude u saved me
Hi Sai!Well done and explained!Thanks for sharing the information!
Great video, you're a natural teacher
Sai you are the MAN!
Whats the code?
Great video. What program/s did you use to make those interactive graphics?
He is just stood behind a clear screen that he is then writing on. It’s very impressive because to him, he will be writing everything backwards!
I have watched many videos, and I can't still understand anything about it
Permissioned Blockchain = Distributed databases
But what about the tracking?
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?
Is block chain a hardware, software or both?
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.
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?
Are you writing backwards on a piece of glass? What is your teaching setup here?
Hey there! We shared some behind the scenes with the setup, on the Community page, check it out here 👉 ibm.co/3bRxRGI 😉
But how is it worth anything as a medium of exchange?
And that this guy can scribe backwards so clearly alludes to a severe lack of deficiencies.
