Nice talk. Block chain is the future. I pray our governments realize that early enough. I hope 0xguard keeps the fight for security too.
The explanation at 6:05 about three friends being able to know what each of them owns on a blockchain is misleading. It runs counter to a blockchain use case: "Let the decentralized ledger keep a record of my transactions without allowing other users I don't trust to associate my assets with me." In other words, "Let the ledger keep a distributed record of my transactions like a receipt so I can prove them, but associate my transactions with a unique identifier that cannot be associated by the general public to me."
⬆️⬆️Since the days was recommended to me I've been referring my loved ones to him….🤗📌.
Very true. Blockchain technology could help channel out a lot of corruptions, briberies, securities when it comes to transactions & transparacy
An online distributed system which can store information – based on interconnected blocks which are open to everyone! Brilliant 👏 l have been searching online and no one was able to simply what Blockchain is. You are very clever 👏 Thanks
The world is about to change.we just have to embrace it.
aww poor Ali was nervous
I don't really agree with this. Lots of these examples would be terrible inefficient and way more expensive if they depended on blockchain and thousands of nodes across the world for verification
Great job dude,
You delivered a nice speech that I understood little more detail about Block chain Technology
Thanks Ali for the explanation of blockchain in simple words. I just had one question can we say that all online website are using blockchain to some extent even when we are paying by cash/card?

Thanks! Best way to put a definition about Blockchain.
Very good explanation except you lost me on the entrepreneur from poor company. You didn’t explain how he gets his loan from blockchain?
Thank you for providing the valuable information
So everyone using blockchain can see my exact account,so in a way there's no privacy?everyone would be able to see bank account balance?
Sir you are great
THE RICH STAY RICH BY SPENDING LIKE THE POOR AND INVESTING WITHOUT STOPPING THEN THE POOR STAY POOR BY SPENDING LIKE THE RICH YET NOT INVESTING LIKE THE RICH.
Thank you for helping me understand what blockchain technology is. I am quite unsure if this technolgy would help most of the people.
Do we really need this?
It seems that “crypto” language is created to help rich countries become richer and poorer countries become poor and thus creating a “gap” and “blocking” them in someway.
