Rebirth: Rewriting Youth

Chapter 179 Small Goals

After sending away Li Meng and the other students in the class, Shen Yu quickly drove back to Xiangzhang Garden.

The owner of a store had already replied, and Shen Yu quickly sent a message: 'Are you still there? '

After a while, the other party responded.

So Shen Yu consulted with his boss about how to buy Bitcoin, and he said he would buy in large quantities.The boss simply sent a WORD file directly, or was prepared, and asked Shen Yu to follow suit and register a Bitcoin wallet first.

Shen Yu hurriedly downloaded it and opened it. The text and pictures in the file were very detailed.After reading it for a while, Shen Yu, who was exposed to the concept of blockchain for the first time, was really confused.

There was no way, Shen Yu could only follow the step-by-step demonstration in the pictures and texts, and from time to time he would ask the sellers in the store.Fortunately, there was no need to jump over the wall. After scrambling for more than an hour, Shen Yu finally downloaded the Bitcoin full-node wallet tool step by step under the guidance of a patient merchant.

To be honest, this hanging wallet is very unfriendly to novices.

最终在得到一个32个byte组成的数组后，沈屿知道，这个就是商家口中所谓的私钥！就是类似5KYZdUEo39z3FPrtuX2QbbwGnNP5zTd7yyr2SC1j299sBCnWjss，这段字符串就是一个私钥。

As long as the application correctly supports the Bitcoin protocol, this string can be recognized as a private key, which can be converted into a public key and then into an address. The generation of public key and address depends on the private key.So the private key is the most important thing in the Bitcoin world!If the corresponding address has Bitcoins, you can use this private key to spend the Bitcoins above.

In other words, whoever writes down this string of characters is the owner of the Bitcoin.The function of the public key is to verify whether the actual controller of Bitcoin is the holder of the private key, thereby determining the authenticity and validity of the transaction.

For Bitcoin wallets, the Bitcoin payment address is similar to an email address. It is a long string of garbled characters whose length is difficult to remember.According to the merchant, with a payment address, Bitcoin transfers can be received even when offline.

After learning that Shen Yu's registration was completed, the merchant asked Shen Yu to quickly place an order on Taobao, and then sent Shen Yu Bitcoin to complete the transaction.

So Shen Yu asked the merchant how many Bitcoins he had.When he finally learned that there were only more than 600 coins, Shen Yu waved his hand and bought them all.

It’s only over 300 yuan, which is really a steal.

Shen Yu silently calculated in his mind that one Bitcoin could be sold for more than 20 yuan before rebirth.

If you calculate it like this, oh, you can easily achieve a small goal!It turns out that making money is really that simple!
"Hiss." After hearing the result, Shen Yu couldn't help but suck in a breath of cold air, and then the corners of his mouth couldn't stop rising.

There is pension money!

"Hehehe." Thinking of this, Shen Yu looked at the screen and giggled unconsciously.

After the transaction was completed, the merchant on the opposite side sent another message telling Shen Yu to remember to synchronize the data on the node.Only then did Shen Yu come to his senses and quickly asked how to operate.

Under the guidance of the enthusiastic businessman, Shen Yu finally figured it out.

The full-node wallet has a very serious shortcoming. It needs to be opened frequently and connected to the network to synchronize the data on all nodes. Otherwise, when it is not used for a long time and is opened again, it will take a certain amount of time to synchronize all the data before it can be used.

Shen Yu thought for a while, then sent another message to the merchant: 'How do you usually save your private key? '

"Just write it down in the notebook."

Seeing the merchant's reply, Shen Yu was speechless. However, after thinking about it, people nowadays don't realize how valuable this emerging Bitcoin will be in the future, and there is nothing wrong with not paying attention to it.

'Well, let's find a way on our own. ' Shen Yu thought this in his heart, but without stopping at all, he typed again: "Can you still get some Bitcoin over there? Can you help me get some more?"

'I have been saving the goods for a long time, but no one is buying them. I kept 10 of them for myself to collect. I won't do anything with them in the future. There is no profit. '

Seeing the merchant's reply, Shen Yu had no choice but to shut up and casually replied: 'Okay. '

"By the way, let me remind you that the full node wallet has too much data and will take up a lot of hard drive space. You can use a mobile hard drive to back it up."

"OK, thanks!"

After closing the chat dialog box, Shen Yu's senses were still very good for this enthusiastic businessman. After all, it was not easy for him to spend so much energy on a business worth more than ten yuan.

'I hope he can keep these 10 Bitcoins forever. Shen Yu prayed to him silently in his heart.

Shen Yu sent Wangwang messages to several other merchants, but after waiting for a while, he still received no reply.

So Shen Yu patiently watched the notebook connect to the Internet and synchronize the wallet data.But I was thinking about how to store this private key.

Relying on the human brain to memorize and manage an array of 32 bytes is very risky. Although there are mnemonics, Shen Yu doesn't think he can remember such a long array for a long time.After thinking for a long time, Shen Yu finally thought of a countermeasure.

You can't put all your eggs in the same basket, so be prepared to buy a few large-capacity mobile hard drives.Register a few more wallets later, back up the wallet programs to the internal hard drives, and then synchronize the data.In this way, you can divide your Bitcoin into many points and spread the risk.

As long as there is a network, there will definitely be traces.For top hackers, even if a dozen anti-virus software are installed on a computer connected to the Internet, it is still a naked chicken.Therefore, devices that are not connected to the Internet are best.

"That's right!" Shen Yu suddenly thought of something, clapped his hands excitedly, and said to himself: "I have to format the computer later! This way there will be no traces!"

Staring at the computer in front of Jin Jin Ye Ye, Shen Yu involuntarily pinched his chin and thought: "How about formatting this computer and then smashing it?"

"Forget it, this computer will no longer be connected to the Internet." Shen Yu chuckled and looked at the computer and muttered to himself.

Of course, in addition to electronic backup, there should also be offline backup such as note recording.

After reading Wangwang's message, there was still no reply, so Shen Yu decided to go outside to get some mobile hard drives and two laptops at the same time.

After making up his mind, Shen Yu took his wallet and went out.

When buying computers in Jiankang City these days, everyone in Jiangnan knows Zhujiang Road!

The 286 computer used by Shen Yu’s mother, Lianliankan, was added to her home after she graduated from primary school. It was provided by Zhujiang Road.

I excitedly ran to Zhujiang Road and bought two laptops, one Lenovo to put in the dormitory, and one Asus to put in Xiangzhangyuan.This way, you don’t have to worry about carrying your laptop back and forth in the future.Then I bought 10 Seagate 500G mobile hard drives in one go.

While walking around Zhujiang Road, Shen Yu saw a bank on the side of the road and suddenly remembered that when watching Hong Kong movies, he often saw rich people storing valuables in bank safes.

So while she was installing programs on her laptop, Shen Yu went to the Aicunbu Bank outside to inquire.The lobby manager told Shen Yu that the safe business is available, but only at the head office!
After getting a positive answer, Shen Yu planned to rent a safe, write the private key on paper, and deposit it in the bank!After all, banks have a very high security level, otherwise how would everyone store their gold?Isn’t this foolproof!
'no! Shen Yu frowned: "You have to keep the private key separately!"They are stored in different banks, so you have to take them all out later and put them together to open the private key! '

After finishing the work, Shen Yu found a bookstore to buy some kraft paper and envelopes, and then hurried back to Xiangzhang Garden.

Take a look at Wangwang, there will be a reply!
Shen Yu quickly contacted the merchant excitedly.

After re-registering three private keys, Shen Yu received a total of more than 400 Bitcoins from the other three merchants, for a total of 1174 Bitcoins!Well, there is pension insurance! (I don’t know how many Bitcoins were produced in 2010, but the news about buying pizza with 1 Bitcoins was from May 2010, so it’s a novel, just read it for fun, don’t be too nervous) Seriously.)
A total of 2100 million Bitcoins have been produced. By this time, Shen Yu did not dare to buy any more, and was ready to close it as soon as it was ready!After all, thinking about the news on the Internet in his previous life, many big names in the currency circle died inexplicably, and Shen Yu did not dare to bet on whether it was accidental or inevitable.

Next, is the long wait.

At this time, Shen Yu was not in the mood to write any Lao Shizi novels. How much money could he make by writing a crappy novel?You must give yourself a day off, no, a few more days off!
The whole operation lasted until around 11 o'clock in the evening, and Shen Yu lazily went back to his dormitory. He just sat in front of the computer, waiting for the data synchronization of each account to be completed, and then backed up to the mobile hard drive.

Back up each data twice to prevent one of the hard drives from breaking, and then mark it with a red-framed label sticker on the hard drive.

Put the four wallet private keys in groups of 8 characters and write them on four pieces of kraft paper with regular tear marks on the edges from top to bottom.Such a piece of paper has 32 characters, but who would have thought that this byte combination is actually four account numbers?

It wasn't until it was dark outside that Shen Yu completed all the work!

Although he stayed up all night, Shen Yu felt that he was still energetic and not sleepy at all!

After all, compared to the income from the book that I worked so hard for a year, it is not as good as a fraction of what I made in one night.

Is this the so-called 'get rich overnight'?
After finding a new mobile hard drive and backing up some files on the laptop, Shen Yu directly formatted the laptop!
After shutting down the computer, unplugging the power, and picking up the laptop, Shen Yu couldn't help but pat it and said, "Old guy, it's time to die. Thank you for your hard work!"

After thinking about it, Shen Yu stuffed the notebook into the corner of the closet, covered it with several layers of clothes, and then nodded with satisfaction.

Taking a deep breath, Shen Yu felt his eyes were a little sore.

Rubbing his eyes, Shen Yu walked back to the living room, opened the refrigerator, took out a bottle of Fujia White, wandered to the balcony, and sat down on the lounge chair.

Looking at the deserted street outside the window, Shen Yu smiled, raised his beer, and murmured to the sky with interest: "Cheers! Good life!"
