  • เผยแพร่เมื่อ 14 เม.ย. 2019
  • Here I showcase how a simple bitcoin transaction (p2pkh) works. It's important to understand the foundation of bitcoin if you want to understand the crypto and blockchain space as a whole. This is just an introduction video. If you are interested in more of bitcoin programming, check out our Bitcoin Programming Course over at our academy. Over there we go into detail into all different transaction and script types and create our own timelocked and segwit transactions plus a whole lot more.

    Hi, Filip!
    Could you clarify how a video, animation fragments, images or 3Dobject for example, to store into the blockchain?
    So, basically, the idea behind my question on how to create a unique digital object using blockchain technology.
    Do I need to use the relation DB for referential purpose, because, it hard to imagine to put in the block huge amount of information(whole 3D object, Movie or Sound Tracks)?
    Could you explain the process, probably in the next part of the Blockchain course?
    Best regards!

    • @filipmartinsson8766
      @filipmartinsson8766  5 ปีที่แล้ว

      I'm not sure it's an idea that would work. But you can store them however you want. Serialize them just like bitcoin or hash them maybe. Depends on what you want to accomplish. The problem is that the objects themselves will probably be too large to actually propagate properly in a decentralized network. The latency would be too big.

    • @RSkyCar

      @@filipmartinsson8766 What I'm trying to accomplish, it's make the digital object (Picture, 3Dmodel or Soundtrack) unique, that's all. I think it's interesting topic to explore. Hope your will dedicate next course to learn this area in more detail in the academy.

    Hey Philip, it's a trip watching u explain via acadamy... I just learned p2sh and having the redeem script but also the Sig's after the fact is crazy secure. The fact that you guys teamed up to teach this and broadcast it was a amazing heavy task. The acadamy is changing my life and you will soon become legend to me. You rock Philip.

    With all of these utxo’s constantly being broken into smaller utxo’s, won’t all bitcoins eventually end up being tiny bits of dust?

    • @filipmartinsson8766
      @filipmartinsson8766  5 ปีที่แล้ว

      Only if people send smaller and smaller amounts.

    • @meredithrose2889
      @meredithrose2889 5 ปีที่แล้ว

      Filip Martinsson seems like with every transaction, some amount will get broken into a smaller amount (for change, fees, etc). More just curious if that was a trend that might emerge when mass adoption happens. Is it more work for the miners if a transaction has a large amount of small UTXOs?

    • @ziomanzo
      @ziomanzo 5 ปีที่แล้ว +1

      If you send a Tx, you can combine multiple utxo's and send it to 1 utxo to to receiver

    • @filipmartinsson8766
      @filipmartinsson8766  5 ปีที่แล้ว +1

      Like fabrice said. Tx fees are small yes, but miners will take thousands and thousands of small tx and just make 1 output. So no, this is not generally an issue.

    Hey Filip, I was one of the early buyers of the first two academy courses (smart contracts and blockchain for business). GREAT content. In looking at the new courses now (mainly Bitcoin programming). I'm all on board for the subscription model, but is there an incentive for people that have bought courses outright previously??
    Thanks for getting back to me!

    What does it mean when people say the real Satoshi can prove his identity by simply “signing a transaction”?

    • @filipmartinsson8766
      @filipmartinsson8766  5 ปีที่แล้ว

      Satoshi owns the first bitcoins that were ever created. They were mined and sent to a specific address and has been sitting untouched for years. By signing a message or a tx with the private key that corresponds with that address, a person could prove that he/she is Satoshi.

    • @meredithrose2889
      @meredithrose2889 5 ปีที่แล้ว

      Filip Martinsson I understand that part, and I understand that Satoshi could send a transaction, but what does “sign a message” mean?

    • @filipmartinsson8766
      @filipmartinsson8766  5 ปีที่แล้ว

      You can sign anything with a private key. So if you sign a message we can see that it comes from that person which holds that private key.

    • @filipmartinsson8766
      @filipmartinsson8766  5 ปีที่แล้ว +1

      You can do this in many bitcoin wallets actually.

      @@meredithrose2889 To sign a message means to take the message and your private key and pass it to a cryptographic function to a get a signature.
      msg + private key ==> signing algorithm ==> (digital) Signature.
      Then, anyone who has the public key (to that private key) can again use the public key + the signature to verify that the signature was indeed signed by the private key to that public key.
      signature + publicKey ==> verifying algorithm ==> match/not a match
