The birth of bitcoin
2008 year 10 month 31 Japan , One department is called Satoshi Nakamoto People who , Published a paper , The name of the paper is Bitcoin:A Peer-to-Peer Electroic Cash System, Translated as bitcoin : A peer-to-peer e-cash system . This represents the birth of bitcoin .
Here is an abstract of this paper .
Interested friends can read the main body of the paper , The main body is not long , Only 9 page , And that's the short 9 Page opens the door to a new world for us .
There is no new technology introduced in the paper , Just for old technologies like :P2P The Internet , Distributed systems , cryptography , The new and ingenious application of consensus algorithm .
This paper solves the problem of currency forgery and double payment in the trustless network environment .
Now the latest definition of bitcoin on bitcoin's official website is an innovative payment network and a new Money:
Satoshi Nakamoto Who is it?
Those who are familiar with Japanese may be familiar with this kind of name , I remember watching an American play Hero When , There's a stop time in it , Even the Japanese who travel through time and space are particularly impressed , That man is called... In American TV series Hiro Nakamura, Translated as Hiro Nakamura . And the invention of bitcoin Satoshi Nakamoto, It's usually translated as Nakamoto .
After Nakamoto's paper , It's time to start implementing the bitcoin system , And finally the 2009 year 1 month 3 Japan , The first bitcoin was born .
The first bitcoin was 50 individual BTC, Now the value is about … forehead ,350W RMB . I'll be out of a suite in a minute .
The above specific information is obtained through the bitcoin block browser . You can get this information in many of these public browsers .
Nakamoto is about 2010 After sharing the last part of the program in mid-2000 , Other work was given to Gavin, the development leader at that time . Anderson .
then , Nakamoto disappeared .
Yes , I never heard Nakamoto's voice again . Of course, a lot of people claim to be Nakamoto , But there's no real evidence to prove .
Whatever the reason for Nakamoto's retirement , But it doesn't matter , Because Pandora's box has been opened .
Why is there e-money
Human beings from the most primitive barter , To the back of the precious metal as a general equivalent , And then to the discovery by the state that money replaces the general equivalent , Finally, to the decentralized e-money .
In fact, I have reservations about whether the last part really needs this kind of decentralized e-money .
Behind money is actually a kind of credit endorsement , If you hold this currency , We can buy goods anytime and anywhere , And the inflation level of this currency remains in an acceptable range and so on , Then this kind of currency is the currency that can be trusted .
We don't worry about not being able to exchange this currency .
In the age of decentralized money , What is the credit endorsement behind it ?
Those who support it will say it's recognition of the algorithm . Just believe in the fairness of this algorithm , And generate the scarcity of money , Such currency is valuable , Can be trusted .
For example , Someone found a kind of stone in a mine , The total number of such special stones is 2100 m . Anyone who can afford an excavator is free to dig this kind of stone , Of course, if your excavator is more expensive , Better performance , Maybe a little more digging .
And then claim that this stone is unique , And a limited number of , It's very scarce .
So here comes the question , When a group of people hotly dug out the stones , I'll sell it to you , Would you buy ? What do you think is the value of this kind of stone ?
In fact, the essence of the problem is whether you think this stone is valuable , Or most people don't think this stone is valuable .
If everyone thinks this stone is good , Then you can go around and buy goods with this stone , This stone is no different from money .
If most people don't recognize the value of this stone , Then the stone can only be spread in a small area .
How to stir up the price of gold with stones , That's what market people are good at . Like the Dutch tulip a long time ago , Another example is an eternal diamond , Take bitcoin now .
Lu Xun said : There is no way in this world , More people are leaving , It's the way .
The price of bitcoin
Let's take a look at the price trend of bitcoin :
stay 2017 Years ago , Bitcoin is very, very cheap , That is to say, bitcoin is emerging 8 In the year , Basically no one believes it .
And then all of a sudden 17 Year to 18 It reached the peak in history , About one BTC It's about the same 2 Ten thousand dollars .
Then there are the ups and downs of volatility , To this day 9 About a thousand dollars .
When it comes to the value of bitcoin , I'm sure to mention bitcoin's first deal :2010 year 5 month 22 Laszler in Japan and the United States • Honets (Laszlo Hanyecz) use 10000 Two bitcoins exchange two values 25 Pizza in US dollars . This is the first time bitcoin has gained a price in the real world .
1 Let's not talk about the value of ten thousand bitcoins . Some things missed is missed .
Love and spare hate since ancient times , There is no end to this hatred !
Bitcoin system
The bottom layer of bitcoin is blockchain Technology , Blockchain can be understood as decentralized distributed ledger , The book is made up of many blocks .
Every time 10 A new block was created in about 10 minutes , Add to the end of the blockchain . The new block records this 10 All the transactions that happened in minutes .
Transactions are used to record the specific information of a transaction . Including the address of the payer , Payee's address , The payment amount , Signature of the payer , Payee's public key 、 The source of the payer's funds ID etc. .
The bitcoin system has the following characteristics :
- It's a P2P The Internet
- There is no need for a third party to issue money , There's no need for trusted third parties
- Everyone can create blocks
- Bitcoin through POW That is to say, proof of workload is used to produce
- Users can use it anonymously
What is mining ?
In the world of bitcoin , We call the process of creating blocks mining . Mining is a reward for the people who create blocks .
Because there are rewards , So we all hope to be able to create this block by ourselves , At this time, bitcoin took a POW, That is, the mechanism of workload proof is used to allocate the mining right of this block .
To put it simply, let's work together on hash The problem of algorithm , Who gives the right answer first , So whose is the mining reward .
So in order to solve this faster hash Algorithm title , All the big mines are trying their best to increase the computing power , In fact, all of these forces are used to calculate hash It's worth it , It's basically waste , It doesn't make any sense .
In the beginning, creating a block has 50btc. From generation to generation 21 After 10000 blocks , The reward is reduced to 25btc. The first 42 After 10000 blocks were created , The reward is reduced to 12.5btc… It can be understood as rewarding every 4 Half a year .
The ecosystem of bitcoin
There's a huge industry around bitcoin and bitcoin networks .
In mining, there are pools and mining machines . I remember earlier, it seemed that bitmainland was listed ?
In bitcoin OTC In terms of trading , There are virtual currency exchanges and market makers .
In the use of bitcoin transfer and account management , There are wallet applications .
In terms of bitcoin payments , There are bitcoin payment services and so on .
So many people around bitcoin , You want to make bitcoin worthless , It seems to be hard .
According to statistics , Bitcoin global trading 80% It's all in China . What's the concept ? You should know that virtual currency trading is prohibited in China . It's still such a big share when it's banned , As one can imagine … It's like real estate .
Most of the computing power of the bitcoin pool is in China . I won't talk about the specific meaning , Let's feel for ourselves .
summary
This article mainly explains the relevant knowledge and development history of bitcoin . There will be more detailed articles to introduce the underlying technical knowledge of bitcoin .
