  1. Nice Video Ivan :). One question I remained in my head: If you have more transactions then you in your example for bitcoin: will the 3 layers be stable and there are a lot of hashes which must be appended together in layer 2?
    Second option could be: only two hashes is allowed to combine and the tree have more than 3 layers at the end.

  2. So in the Blockchain we just have the merkle root?
    When I have the Data A, I need the hash of the other hashes, even if they are offline, but how do I get them?

  3. What I dont understand is how do I validate a transaction if only a Merkle root is stored in a block, and no branches? Then I still need to calculate the whole tree from scratch. And compared to calculating a hash just from all the transactions, I will need to calculate it again in order to find all the branches. So the only reason for Mercle tree seems that is strengthens sha 256

  4. I don't understand how you don't care about the other branch when you validate the "A" transaction, because the final hash is a result of the hash from AB and CD, so you should care about the CD hash

  5. great explanation. I've read a lot about Merkel trees. it took me several readings before I developed even the most basic understanding. wish I would have come across your explanation sooner. would have saved me a lot of time. thanks.

  6. Merkle tree it is then.
    Hvad med at tale lidt om EOS og Bitshares? ups nordic language 🙂 What about talking a bit about EOS and Bitshares from what you think would be Daniel Laramies meaning with the new project please?
