Great video, I not only learned about proof of work but about how hashing works in general which is probably even more important.

hi, great video dude this has opened my eyes a bit on how proof of work works... so can I ask perhaps a silly question - the hashing that the miners do, to calculate the hash value, is that then the value that makes up the 'previous' hash of the next block?
@ptondt

Hi Caleb, last question here for this video: 1) Regarding the merle root tree, is the double hash process including the miners' coinbase transaction performed by miners as well? 2) Additionally, for the transactions, what determines which transactions to be included in the merle root tree? Is it the same for every miner? (except the transaction to the miner itself) 3) The mining process, will it only commence once the block has been closed and will not be taking on any more transactions? Or how does this work? (Probably also relates to the previous question as to how (if all transactions are the same for all miners) this is determined by the blockchain and communicated to all the Miners. (Maybe full nodes have to do something with this communication?) I want to thank you again for this very informative video series, you've made me understand a lot more things :D Keep it up!

Bro, did you read satoshi Nakamoto book? You can find all the emails written by him responding to all of this questions. You can download this pdf anywhere. "Bitcoin: A peer-to-peer electronic cash system"

Learned so much by this video, just a small doubt, who validates the transaction like if the transaction is really valid or not?

How are the "leading number of zeros" in the target hash value related to the nonce, if any at all?

Your video is pleasantly easy to understand, however there is still something I don't understand from your explanation . at 13:10 you say the hash would be different but aren't we trying to validate the same transactions into the blockchain?
@the_real_vdegenne

@@tomlatham8482 Looking back on my comment, I think we are talking about the nonce here, the transactions we're trying to confirm are the same but we are competing to find a hash and the input is the transactions + a nonce + the variable input your mining program modifies to find the hash. Now I don't know much in details but the nonce could just be computed from your bitcoin address which is unique to any user. Head me up if you find anything useful from your research 👍
@OnionKnight541
@OnionKnight541 7 месяцев назад
how do other "full nodes" test the input to check it? i have a sense that that would be automatic, but it's not clear. and by "full node," you mean, some other guy on the network with a computer that is running to bitcoin protocol (?)?

Hey , does anyone know what happen to the transactions that haven’t been confirmed , do they just vanish ?

Dude excellent video. You delivered a lot of complex stuff in a really digestible way. One hopefully constructive criticism though (and this is coming from a complete crypto-noob so maybe this is common knowledge), but for me at least I think I would have had a better understanding of PoW if you had taken a moment around 16:00 to: (a) define the coinbase/generation transaction and (b) talk about the significance of that transaction's payout address in making unique Merkle roots for different miners from otherwise identical sets of transactions EDIT: Also cool you touched on the NP-ness of finding a pre-image that hashes to a given value

So...if I try to send $10 to you and $10 to Ally, then Proof of Work determines which transaction gets added to the blockchain first. Proof-of-Work also forces validators to spend computation power before the crypto network will listen to them, thus securing the network against malicious validators. Am I understanding this correctly?
