Blockchain Explained

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.

Check out this lightboard video with Sai Vennam from IBM Cloud as he takes a deep dive into blockchain technology and covers everything from smart contracts to permissioned and permissionless blockchains

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

[_romeopeter]

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

[Fahdie]

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!

[christianfaust]

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!

[eddiebkheet]

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.

This video definitely helped me to understand the overview of blockchain more

[asfand]

Thanks for this video, gonna talk about it for a interview I have at IBM in a few weeks lol

[zarakmaxful]

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

[steveday]

Finally someone explaining it clearly in English not talking 20 miles in a minute.

[hannesjana]

Thank you for a good explanation. I can recommend this video. It definitely helped me understand the concept better.

[mannymorales]

Thank you for producing and sharing this wonderful and insightful video!

[sexyeur]

Haha wow. This guy can write backwards perfectly!!!!

[chakshujain]

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

[danielemessina]

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.

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".

[hightek]

A permissioned blockchain is just a database!

[mhn...]

Hi Sai!Well done and explained!Thanks for sharing the information!

[carbon-structure]

Great video, you're a natural teacher

Did you make the video readable by mirroring it vertically?
If not, this guy is brilliant!
