Hello everyone, welcome to the "Quality" channel This channel is mainly about blockchain, Blockchain technology And related content This video is the "Creation" video of this channel
So I want to talk about it Bitcoin's "Creation" block Excavating the first block from Bitcoin It has been more than 10 years That is 2009 Before we study the Bitcoin creation block I want to introduce it first Bitcoin blocks and transactions Let's take a look Bitcoin Is made up of a chain of blocks You can see Every block Is made up of some transactions List here (List) Not a list inside the real data structure It is actually a tree This we can talk about later, it is a Merkel tree Every block Will have a hash pointer Point to the previous block Every block is like this Add one by one at the end Every transaction in the block Contains "Inputs" and "Outputs" Let's zoom in on one of the deals Every transaction Must have "input" or multiple "inputs" And "output" or multiple "outputs" "Input" is Some currency that was not spent before "Output" is Who is the bitcoin called to? Bitcoin from an address Send to another address The principles here are: You have to use all the "Inputs" Transfer to all "Outputs" Of course, you can have multiple "inputs" and "outputs" In all transactions There are actually two types of transactions One is (for example): Someone has 8 bitcoins Then I sent it to Suppose there are 8 bitcoins that are Alice Alice has 8 bitcoins These 8 coins are either dug by myself
Either someone else gave her This is the "input", the input corresponds to The "output" of a previous transaction Alice wants to transfer 4 coins To Bob In this case, the remaining 4 coins Transfer to herself It is emphasized here that you must use all the "inputs" Then the rest will return to her own There may be other remaining As a transaction fee, we will talk about it later There is also a special kind of transaction There are no "Inputs" "input" the data structure in the transaction Is a list (List) The "input list" for this type of transaction is empty But there is a special field in "input" CoinBase I think we used it The name of CoinBase, which buys and sells bitcoin or other digital coins It’s from here CoinBase this field The miner can put anything in The "Outputs" here are the bitcoins that have just been dug up This special transaction Is the process of bitcoin production It does not transfer any coins Bitcoin’s creation block also has no coins to spend It doesn't have any "input" "Output" is the coin just dug out Based on this information Let's see Genesis block This is the block numbered 0
you can see There is only one transaction in this block Trading "Output" has 50 BTC BTC is the symbol of Bitcoin The timestamp of the block is 2009 January 3 The time to receive this block is also January 3, 2009 Let's see The only transaction in this block Click inside to see Here is the transaction size, volume Time of receipt of this transaction Important fields are here This CoinBase field This field is encoded in base58 Decode it out The Times, January 3, 2009 The British Chancellor of the Exchequer wants to use People's money assistance banking Let's go see that one The Times This is the Times of January 3, 2009 The title of the front page is The Chancellor of the Exchequer is on the verge of implementing the second round of bank emergency assistance This is 2009 This is the second year of the financial crisis in the United States
The crisis swept the world Blockchain information is a satire on capitalism Also shows why Bitcoin has a need to exist Bitcoin creator: satoshi nakamoto thanks for watching If you have any content you want to see, please leave a message If you like this video, please subscribe to this channel thank you all!
