I believe that everyone has already guessed that everything that Musk experienced, including the small bookstall and the yellowed notebook, was actually Boss Jia's masterpiece. Otherwise, would Boss Jia really let Musk, a time bomb, take over the Daqian phone?
Boss Jia's purpose of meeting Musk was to let him get the concept of Bitcoin and get out of here.
As for why Boss Jia did this, that was the answer to be revealed later. Let's not talk about it for now.
Let's go back to Bitcoin. What is this Bitcoin?
It's very complicated, but it's also very simple. In fact, Bitcoin is essentially a string of passwords, a string of passwords that is unique in the entire network.
It sounds very unbelievable that a string of passwords can be worth more than 60,000 USD. Why? What can a string of passwords do? Can it open the Daqian's bank account?
Of course not. However, if you think about it another way, a pile of 60,000 USD bills is just a pile of paper. It's even worse than passwords.
A step further is the digital cash in Alipay. To put it bluntly, it's just a string of data. It's even worse than paper.
In fact, the fundamental reason why all the money in the world can be maintained is not because of what the money can do, but because of the trust behind the money. Everyone believes in the value of the money and is willing to use their own products to exchange for it, which means that the money is valid.
Almost all the money in the world is backed by the credit of the country because personal credit is worthless in the face of money.
However, Bitcoin is an exception. Bitcoin is not backed by the credit of the country, but by the credit of the entire network.
Next is the process of the creation of Bitcoin.
I believe that everyone must often use Bitcoin download because this download method is indeed much faster than other traditional download methods.
This was because downloading files was different from traditional downloading. Traditional downloading was downloading files from a fixed server. Although the stability and network of this server were very high, a single server had to deal with thousands of downloads, and the download speed was very slow.
However, it was different for X Download. He did not download it directly from the server provided by the service provider. Instead, he downloaded it directly from the computer of the user who had already downloaded it.
For example, there was a user who had a very good movie, but this movie was not suitable for public download servers. Therefore, he made this movie into an X file and then posted this file on the Internet. At the same time, he made sure that his computer was connected to the Internet.
At this time, if someone downloaded this X sub-file and double-clicked to use it, they could directly enter the publisher's computer through the network and download the movie.
Once the download was completed, the two people's computers would have the movie and the seed. In this way, a third person could download a part of the movie's data from the two people's computers at the same time. This way, the download speed was greatly improved.
Then, three people became six people, and six people became twelve people. Anyway, as time passed, more and more people had the same movie, so the download speed became faster and faster. This was because the download work was distributed to hundreds and thousands of private computers instead of a single server. Naturally, the download speed was faster.
In this way, each computer took out a part of its own computing resources, network resources, and storage resources, and gathered together to form a large network body. This was the peer-to-peer network, which was the concept of a P2P network.
After understanding this concept, let's continue to understand Bitcoin.
The process of the birth of Bitcoin was actually not complicated. It was a process of solving a mathematical problem.
The creator of Bitcoin, Satoshi Nakamoto, listed a very complicated set of equations. You didn't need to know what this set of equations was. You only needed to know that this set of equations did not have a fixed solution. It had many different special solutions.
As for how to solve the solution to this equation, users didn't need to worry about it because Satoshi Nakamoto had already provided an open source Bitcoin mining knife software. Using this software, one could directly calculate the special solution of Bitcoin.
At the same time, according to estimates, because the number of special solutions was limited, the number of Bitcoins was also limited. At most, there were about 21 million Bitcoins in the world because there were only so many special solutions to this equation.
When the first person used the Bitcoin mining knife software to solve the first special solution, the Bitcoin mining knife software would reward the solver with 50 Bitcoins. Then, this solution, as well as all the transaction data changes that occurred within 10 minutes, would all be packaged into a data package and stored on the peer-to-peer network mentioned earlier.
This data package was called a block, and the first packaged data was the first block.
When a user solved the second special solution, they would also be rewarded with 50 Bitcoins. Then, all the transaction data within 10 minutes would be packaged into a data package.
This data package was the second block, and the first block and the second block were connected to each other through the peer-to-peer network. After that, the second block was also connected to the third block, and the third block was connected to the fourth block. Finally, a long chain of countless blocks was formed. This was the so-called blockchain technology.
This blockchain would automatically be stored in the computers of all users who installed the Bitcoin mining knife software. Of course, some people might choose to delete the data.
But it didn't matter because there were already countless identical blockchain stored in countless computers, which was equivalent to having countless data backups. It was absolutely safe.
Bitcoin itself was a string of passwords. When you uploaded the special solution to the Bitcoin mining knife for verification, all the connected Bitcoin mining knives in the world would verify your special solution at the same time.
As long as the special solution was brand new and was completely different from the other verified special solutions stored in all the mining knives, the mining knife would automatically generate a Bitcoin private key, which was a string of complicated passwords that couldn't be solved at all, and send it to a Bitcoin address set by the user.
At the same time, the Bitcoin mining knife would also generate a public key corresponding to the private key obtained by the user. A private key could only open one public key.
Only the user had the private key, but the public key was stored in everyone's computers.
When conducting a Bitcoin transaction, only by opening the private key with your public key could the transaction be carried out. In this way, the Bitcoin mining machine would generate a brand new private key and send it to the Bitcoin address of another user who spent money to buy your Bitcoin. In this way, the user would lose the private key, and the Bitcoin would be equivalent to being traded to another person.
This was the basic structure of Bitcoin. Everyone might be a little confused, so let's make a visual analogy.
First of all, let's assume that a person's circle of friends could be added infinitely, and it was always visible to all friends.
Then the owner of this circle of friends posted a question on WeChat: What is a fruit?
Then all the friends could post a picture of a fruit under the picture. Then all the friends who added this circle of friends, if they thought that the picture was indeed a fruit, and this fruit had not been posted by other friends before, they could like the picture.
Only when more than 90% of the friends liked the picture, then the picture of the fruit would be recognized. At the same time, the system would automatically give a string of password to the person who posted the picture, and this password was Bitcoin.
At the same time, all the friends would also get a corresponding password box. At the same time, everyone would remember that there was a Bitcoin placed on someone.
If someone wanted to trade this Bitcoin, then he first had to leave a message, saying who he wanted to give the Bitcoin to.
Then he would send his own password to open the password boxes in everyone's hands. Only when these password boxes were all opened, could he get the unanimous approval of all the friends.
So the system took back the original password, then generated a new password and gave it to the person who was given the Bitcoin. At the same time, a new corresponding safe box was generated and given to all the friends.
Well, it was roughly like this process.
So in fact, blockchain technology was not very high-end. To put it bluntly, it was just data packets connected together. Any high school student, or even junior high school student or elementary school student, as long as they had the corresponding network programming knowledge and connected to the Internet, could create a new blockchain.
