    Structure of blockchain

    A block consists of 3 parts

    1. Header : It has version information, nonce, previous block id and timestamp

    2. Merkle : It is a hash built from the block's transaction identifiers

    3. List of records : It is an identification of hashes that were included into the block's Merkle tree


  2. Not to take away from your stellar videos, for which I am grateful, however reducing some reverb in your voice and/or using more sound dampening techniques would give your voice more direct power, hence greater effect. ? Please don't hear what I'm not saying. Your videos are awesome and some of the most helpful. Just giving some perspective on the impact of audio as someone with a background in this area to help you impact more people. Blessings ?

  3. Hey on the application regarding tracking food, I don't understand why you need to use blockchain , all it needs is constantly tracking it – it doesn't require publicly broadcasting the data. So why do you require blockchain? Please correct me if I'm wrong.

  4. Quick question: for the examples (such as the food example) in the beginning – when smart contracts haven't had been mentioned yet in the video – wouldn't we also have to create smart contracts? In the case of the food example: each piece of food e.g. a steak when created is identified via smart contracts on the blockchain. Thanks a lot in advance!

  5. Oh my! This technology needs to be incorporated with Statistics. Why? After learning it, I understood that you can pretty much make a statistic say what you want it to say by the collection of data or the presentation of such said data.

  6. 3:00 the significance of this rings totally different after 2020…
    Still, doubters would still find a way to doubt, I'm sure.

    Another great use for the blockchain going forward, would be for fact-checking.
    Imagine having it all securely validated… it would be a great solution to derail the spread of misinformation, that become practically viral (more so than the actual covid virus) after the way social media platforms made it so easy to spread.
