The Traditional Textile Industry Is Equipped With Hot Technology "Block Chain", Changing The Road To Overtake To Create A New Field.

Recently, the three words of "block chain" appear frequently in front of us. Whether they are friends circle or push articles, we can find traces of it. But what is the block chain? How amazing is he? Can he bring subversion and adventure to the textile industry today?

Then, please read the following text carefully, and ensure that you can chat with friends about the chain.

In order to ensure that we can simply explain the block chain without looking at the full text (taking care of those who earn tens of thousands of minutes and do not have time to read books), we first make a summative definition of the block chain: "block chain is a distributed accounting technology", which is still a bit muddled.

In terms of personnel, it is called "block chain," that is, we divide our books (data) into small chunks or small pieces according to the time interval, and connect them in series according to the time sequence, and then copy many, many copies in different places. Of course, the data block is transmitted by network and recorded by computer.

Next we will have a detailed understanding of the block chain. We will explain the block chain technology through three topics today: 1, the category chain of life, 2, bitcoin and mining, 3, what is the essence of block chain?

Category chain in life -- account of Niu Tau Village

Once upon a time, there was a small village called Niu Tun Village. The village implemented a collective economy (big pot), and the record of work and income and expenditure of the villagers were recorded by Mr. "cattle accounting". The cattle accountant had a large account, recording these things, because the cattle accountant had to keep accounts for everyone, and he did not have to go to work. At this time, the accounts in the village are like this.

Finally, one day, a villager accidentally saw the book, looked at the book, found that the villagers' work and income and expenditure records were wrong, the most critical income, expenditure, balance and other figures are completely incompatible, so that can not be done, and then he immediately told other villagers.

We strongly condemned the convening of a village people's Congress after accounting. The conference held a heated discussion and reached an in-depth consensus. The conference decided to "remove the accounting position of cattle" and began to record accounts from the beginning of this month, starting with Zhang three, and then next month, Li Si, Wang Wu, Zhao Liu and Chen Qi. At this time, the account of Niu Tau village became so.

It was safe for several months. Until one day, the boss of the village head restaurant, Cui Hua, forced Li Si to pay for the wine and vegetables that he owed. Four, he was forced to think about how to make money. He looked at the public funds and books collected on the table for several days, and decided to embezzle public funds. But he was afraid that this matter would be discovered by the people who kept accounts next month. What should I do?

Li Si decided to burn up some of the contents of the account so that no one else could find out. If you tell people to burn the candles off, you will be most scolded.

Sure enough, we had no choice but to burn the candles. But then Wang Wu accidentally overturned the candles, Zhao Liu was bitten by rats, and Chen Qi was bitten by a dog. This will not work. Will the accounts in the village be chaotic?

So we held the second big village meetings. The meeting first condemned each other and reviewed itself. After another discussion, we reached an in-depth consensus. The meeting decided that everyone should send a book. Everyone must keep accounts. Everyone and the changed account must tell others. After receiving the news, everyone else should write a note on their books. If anyone finds that the new change accounts are not right, they can refuse to accept it. Every night everyone will reconciliate the accounts with the majority of the people. At this time, the books in the village became like this.

Sure enough, after using this method for a long time, there was nothing wrong with the books. Even if someone had broken down a part, they could just copy the others.

However, gradually some people began to be lazy, and did not want to be so troublesome to sort out accounts and keep accounts. They hoped that people would check it out with the last time after they had taken a good deal, and that they would be able to copy it directly without any problem. The people who had worked hard at that time had their opinions. After having their opinions, they urged the village committee to convene the third village Congress. In this way, the third great village conference was held in a timely and accurate manner.

As usual, he strongly condemned the lazy bookkeeping people and accepted their self-examination. After a heated discussion, we reached an in-depth consensus, and the meeting decided that "everyone will come to the village Department early tomorrow. We will throw the dice. We will decide which accounts will be collated and recorded according to the number of dice, and check the accounts at night. The others will just copy it after checking, and at the same time, those who are rocked to the bookstore every day will get a reward of a certain proportion of the total amount of the day." At this time, the books in the village became like this.

At this time, it solved the problem of misappropriation of public funds, bad accounts and bookkeeping.

Bitcoin and mining

Bitcoin (Bitcoin, abbreviated BT) is a digital currency with a constant total value of 21 million.

So why is bit a block chaining technology? This requires a detailed understanding of his accounting (data storage) and transaction verification logic. Next we will explain bitcoin from the development of Ngau Tau Village's currency.

Time passed quickly, really fast. Influenced by the outside world, Niu Tau village has also undergone several changes in this long time. Its transformation is magnificent, changing from day to day, and the result of the right choice of the Ngau Tau villagers.

After exploring and summarizing several generations of village committees, the village head and the old secretary found that the collective economy hindered human progress and hindered the development of the village economy. Only by competition can the Ngau Tau village become more prosperous. Therefore, the second session of the N village people's Congress was convened. It was also an incentive discussion which reached an in-depth consensus. The meeting decided to change the collective economic system to a contract system. The fish ponds, pig farms and land in the village are contracted to individuals, and we exchange them in a mutually agreed currency. The meeting also decided to use rare (not too rare to be pirated) gold as an exchange currency, and stipulate that all the gold in the village could not be mined. Only the village committee could exploit the village. The village committee made the gold into circular pieces to facilitate circulation. According to the labor force of the big family, the gold blocks were distributed to everyone according to the equivalent value of the goods delivered, and we could also buy the labor and goods of other villagers with the small pieces of gold on hand.

This idea is wonderful. After implementing this method, the villagers became more industrious, because only gold pieces could buy materials, and material could lead to a good life. Everyone worked hard to exchange for it, and the village was also developing rapidly.

But it did not last long. The gold mines in the village were less and less. Mining and smelting were also laborious. In addition, gold was rather worn out in the trading process. What was even more strange was that the gold was shining beautifully. Many villagers made him into jewelry, and the Yellow Gold in the market slowly became less and less. Many villagers could not get gold pieces to exchange materials.

The village head meant that this series of validation problems once again organized the N+1 village people's Congress. The meeting first strongly condemned the villagers who took the gold to make jewelry into small animals, and then heated discussions and reached an in-depth consensus. The conference decided to "replace the gold block transactions with a sheet of paper. All the villagers took the gold pieces and gold jewellery and gold animals in the hands to replace the equal amount of paper. This is not ordinary paper, only the paper stamped by the village committee is effective, and can be used as a transaction." Indeed, with this method, it is much easier for us to trade, and we do not have to waste our manpower to smelt gold.

But after a while, there was a problem with paper money. Many villagers complained that the paper money was often lost or destroyed. The village head and village cadres were even more ridiculous. When they wanted to spend money, they would draw a piece of paper, then seal the village committee and then take the deal. This problem is even more serious.

The village head had to convene the N+2 second village people's Congress again. The meeting first strongly condemned the small village chiefs and village cadres who took the paper to scribble and then took the transaction, and then reached a deep consensus after a heated discussion. "Starting today, canceling the paper currency transactions, we used the form of recording accounts, handed all the banknotes collected to the villagers' committee, and then the village accountants took a number of equal figures for each of them according to their names. After all the transactions were told to the accountants, the accountant would write a record of the increase or decrease in the accounts of both sides of the transaction." After the implementation of this method, the problem of banknote loss and village cadres' money making has been improved, and Niu Tau village is thriving.

But it didn't last long. It was not long before many villagers found that they had been eating spicy drinks since they kept accounts for themselves, and some of the villagers' bills that had been paid by the accountants had not been able to match their records. It must be the accountant who adds more numbers to himself, and the number of people who have offended him. So the village governor once again felt the seriousness of the problem.

Then held the village Congress of the N+3 people's Congress. The meeting first strongly condemned the village accountants, and then held a heated discussion and reached an in-depth consensus. "We should not find anyone to keep accounts. We should find a safe way to keep accounts, but what is the way?"

At this time, a student named "Zhong Ben Cun" in Niu Tau Village university came out. He said he designed a system to solve this problem. First of all, we need to restructure our accounts.

1, open accounts, so that everyone can see the transaction figures.

2, do not remember specific amount of figures, only record transactions, to know the balance through the calculation will know.

3, we must use online money to circulate and name it "bitcoin".

4, everyone's home computers and mobile phones have to download this system, and then use this system to transfer transactions. This system is called "bitcoin system".

In this statement, the villagers exploded the pot and did not record the balance. They could not accept the public accounts, so that no one knew how much money my family had.

Nakamoto So said, "don't worry. For privacy and safety considerations, all of us do not trade with real names. 。

• I randomly generate a bunch of numbers for each person. This number is your password. The password is the only proof that you have bitcoin.
• I will generate a numeric account for you according to your password, and then give you a person's address, which is unique and will not be repeated.
• If you want to collect money, you can only tell others your account name; if you want to pay, you need to tell your account and user name address. This solves the problem of open privacy and transaction security during transactions.

The villagers feel that this method is good. Whose computer records the transaction books? We don't believe in cattle accounting and village cadres. If they change the data of the books, if they fail, they will not be able to trade, or if they lose their account data, what do they do?

Chung Ben Cong said: we do not look for any person to keep accounts, but all the villagers' computers are involved in bookkeeping. After every transaction system will be notified to everyone's computer through wireless routing. The computer will record, that is, everyone will have records of these transactions. Then we find a person to put these transaction data into a bill, the bill after finishing, and then sent to all people, we use the transaction data before to verify the bill is not correct, after verification is correct, save the page bill, the error is refused to retain, after we have verified this bill, the system will calculate whether the page bill is verified by most people, if so, the bill is verified, all transactions recorded on the bill are effective, if only a few people pass the verification, then all transactions on this bill will not be effective.

People who do not pass the bill before the bill comes into effect will also have to keep it. The system will link up the bills in your computer according to the time sequence, and link them into a complete bill.

The villagers felt that this method was feasible after hearing it, but who would check the bill?

In the village again: it is very hard to arrange the bill, so we must be rewarded. The system will bring out the sum of the sum of X% of the transaction data in the consolidated bill as a reward for arranging the bill.

The villagers thought that this good and reward would be willing to sort out the bill, but everyone wanted to sort out the bill, so who would it be sent to?

Zhong Ben village again said: we are not issuing bitcoins. Our bitcoin is issued in this way. "Every 10 minutes there will be an arithmetic problem. All villagers can participate in the calculation. Whoever first calculates the problem, we will reward him with 50 bitcoins, and all the bills within 10 minutes will be handed to the man to sort out". I have taken several very impressive and memorable names in the whole process of recording our entire account. What is the name?

1. The process of calculating arithmetic and competing for the right to settle accounts is called "mining."

2, the bill that is sorted out every ten minutes is called "block".

3, the book that links every page bill in chronological order is called "chain".

The villagers have problems again. This method is good, but every 10 minutes, there will be an arithmetic problem and a bill. If we get the reward, then we won't have any bitcoin in the past few years.

Zhong Ben Shen Shen has perfectly solved this problem. He said: our bitcoin has a total circulation of 21 million. The first time to get the right to record is 50 bitcoins. Every record of the 210 thousand bills is rewarded by half, and so on, so we don't have to worry about inflation. Money will become harder and harder to earn.

Since then, the technology of block chain led by bitcoin has come into being. Is Nakamoto So a teenager special?

What is the job of block chain?

After seeing the change of account books and currency reform in Niu Tau Village, we have a basic understanding of block chain. Now let's summarize what the essence of block chain is.

Block chain is a computer technology of distributed data recording. It is to use the server to record and support the operation of a total Internet product, which is supported by many servers. Any server's data disorder, downtime and hacking are not affecting the real data produced by the Internet, unless more than half of the servers have the same problem.
