  1. Let's say, with block chain A>B>C>D, you tamper with block B. How would that affect all following blocks, or even just block D? Wouldn't tampering with B's hash only affect B's hash and C's previous hash?

  2. Prove of work (i.e. proof of waste) can safely be replaced with proof of stake. Faster and basically no elcetric bill. Shame that Bitcoin doesnt use that yet.

  3. Just wanted to say I'm citing your video in a paper I'm writing for my health information systems class. My professor also showed your video in class one day a month or two after I had found it. Needless to say, this video has been quite helpful for explaining blockchain in a way which is easy to understand lol. Thanks!

  4. This was very good, but left me with a couple questions. How is mining done, I think I understand that it is the act of processing these transactions and generating the proof of work, but then somehow a bitcoin gets created and given to you for your "work" but at some point there will be no more bitcoins available, so why would anyone do the work of processing the proof of work anymore, and how would the ledger stay current?

  5. @… Blockchain = a virtualized handshake … wow !!! 😀 … dencentralized … wow!!! 😀 …. everything you need preventing eyecontact with Hitler … for one eyecontact at least 1000 Watts … and then your toilet also can send message about the color of your shit

  6. Intresting how these conversations were being had and most had no idea of it.

    Now this tech has become so wildly mainstream that most (me lol) are playing catch-up trying to better understand this all.

  7. Thank you for giving me information about blockchain. Theoretically, it looks so secure and wonderful, because it can assure that exchange can't never be changed. Hopefully, blockchain, which is such a great tool, will become a main component of any monetary system in the world.
