bitcoin is actually an e-coin data coin proced by P2P batch software, which belongs to a network virtual asset so bitcoin is also called bitcoin. It is generated by a set of cipher codes through complex algorithms. This rule is not interfered by any person or organization. Anyone can download, run or participate in the manufacture of bitcoin. One of the biggest characteristics of bitcoin is that it cannot be forged< you can make money in the bitcoin market by investing time and money 
when you spend time on websites, you can visit these websites every few minutes to get a small amount of bitcoin. Therefore, we can do this if we have time. If you want to earn more, you should invest money in the early stage. Bitcoin also has a special casino, so you can earn more by luck
1. Mining can not only proce bitcoin, but also guarantee transaction information
similarly, a mathematical system contains 21 million mathematical problems, so we need to constantly seek the special solution of each mathematical problem through a huge amount of calculation. In addition, the special solution is unique
mining can not only increase the supply of bitcoin money, but also protect the security of bitcoin transactions and prevent fraulent transactions. In terms of process, bitcoin network is a point-to-point payment system, and anyone can trade through the transaction program
in order to ensure that the transaction process is truthfully recorded, the role of "miner" is required to be responsible for recording bitcoin transaction information. The time interval is 10 minutes. The best recorded transaction records among miners will be packaged and stored in a new block, and the corresponding miners will also receive a certain amount of bitcoin rewards
2. The mining process is extremely complex, which is beyond human power
the specific process is as follows. When a miner listens to the transaction, he will first verify the transaction information. The verified transactions will be recorded by miners and stored in their own database. There may be thousands of miners in the world doing the same thing, but every ten minutes, only one miner has the right to create a new block, so that the transaction information recorded by himself can be recognized and stored permanently
next, miners need to fight for the right to keep accounts. This is a competition of computing power. The core of this competition is to use computers to complete a large number of calculation tasks and find a super difficult random number. This random number is the special solution of the equation mentioned in the first paragraph. The miner who calculates the correct random number first wins. According to the rules of the game, the probability of a miner getting the accounting right is directly proportional to the proportion of his computing power in the total computing power of the whole network. In other words, the probability of finding the random number is equivalent to throwing out 100 million dice, and the total number of dice is less than 150 million. Therefore, mining requires a large number of computers, installation of specific algorithm software, repeated operation day and night, not human
3. Bitcoin mining is actually "villagers' bookkeeping"
maybe some netizens still don't understand, let's take an example. In a village, the villagers often borrow money from each other, even if they write a written document, there is a risk of default. Then, every time there is a loan behavior in the village, we will use the village trumpet to inform everyone that all the villagers (miners) will record all the transaction records in their own account books.
How to evaluate Li Xiaolai, a New Oriental teacher who is worth 10 billion by bitcoin
according to the self claim and related description, Li Xiaolai has the following aura:
China's richest man of bitcoin
one of the most domestic holders of bitcoin
New Oriental master
author of many best sellers
famous angel investors, etc.
are you surprised? Looking at the background, Li Xiaolai is also a big man, but few people seem to know him well
on the contrary, it is Luo Yonghao, who was mentioned by him, who is well known in the science and technology circle
but Lao Luo never interacted with him after he became famous, whether it was the most beautiful New Oriental period or the most painful mobile phone with a hammer
who is the "richest man of bitcoin in China"? Let's take a look at his history
When Li Xiaolai was a student, he won many awards in computer competitions. In his sophomore year of high school, he participated in a competition held in Jilin Province. He was originally the first to win the competition. Because of a teacher's protest, he was canceled. The top three in this competition were recommended to Tsinghua. Hit by this, he did not play a normal college entrance examination, into Changchun Universityafter graation, I started sales first, and I once worked as a general agent and made a lot of money. But because he was treating his father, he ran out of money
Later, like Luo Yonghao, he went to New Oriental. On the one hand, he became a teacher of English, on the other hand, he published "21 day breakthrough of TOEFL core vocabulary" and other booksthere was nothing special here, until he met bitcoin
In 2011, Li Xiaolai learned that the transaction price of bitcoin exceeded $1. Although he didn't understand why it was so expensive, he bought 2100 coins in the first placewhen bitcoin rose to $24, he decided to "mine" and buy hardware equipment to dig coins. As a result, we didn't succeed this time. We invested more than 600000 yuan in partnership with others and only got more than 100 yuan
However, through this experience, he devoted himself to the field of virtual currency. Since then, there have been continuous acquisitions. Until the end of 2013, the Wall Street Journal mentioned:"a newly established group of bitcoin observers in Beijing said that Li Xiaolai, 41, is one of the most bitcoin holders in China. Li did not want to specify the amount he held, but said he held six figures, with the first digit of one. In other words, the value of bitcoin he holds has exceeded $100 million. "
What is life like after becoming a billionaire According to Li Xiaolai, one is to learn general ecation course, called "seven years", which enables people to learn skills; The other is the business school, which is called "growing together" to learn and share in the instrypublished a book, "seven years is a lifetime", and played a new trick: pay more than 2500 yuan, you can enter a group. What are the advantages of joining this group? Chapter updates of this book will be in this group first
open a column, and open a column "road to wealth and freedom" on the app. Each paying user needs to pay 199 yuan. In 2017, his column users have exceeded more than 100000, that is, he has gained more than 30 million in this column
a person who has already been rich and free can teach "the road to wealth and freedom" on a knowledge payment app with a small audience
It's always fun to think about itmaybe, as Li Xiaolai wrote in his Internet entry, "strive to make some intellectuals rich first"
in fact, Li Xiaolai has not yet shown people the evidence that he owns 10 billion bitcoins, which is very simple and there will be no loss, but he has never done so. Therefore, it is doubtful whether he owns as many bitcoins as the outside world
all the information about his worth of 10 billion bitcoin comes from his unilateral statement to reporters. Around 2013, when bitcoin began to be popular, the financial headlines of major media began to introce the legendary figure who was a former New Oriental teacher. Li Xiaolai told people that he started to be the upstream instry of bitcoin two years ago, renting factory buildings in a place where there is no shit, and using cheap land rent and electricity cost to mine
of course, many people don't buy it. They ask Li Xiaolai to show evidence. They just need to make his wallet public. Because of the encryption design of bitcoin, such display will not affect his financial security at all, but Li Xiaolai always avoids talking about it
because for Li Xiao, no matter whether he has so much money or not, it's his best strategy not to show it publicly, because it will give people a sense of mystery, a sense of shadow wealth, and help him with other businesses
No matter whether he has 10 billion worth of bitcoin or not, Li Xiaolai seems to be a successful person, because he is always on the cusp of the new wave in recent yearsWhy do small enterprises need law and large enterprises need law? Because enterprises need high human cost to improve, supervise and implement the management system. And the department work of small enterprises is not saturated, so the management can not proce benefits, so the boss is unable to support the human cost. If there are too many managers in an enterprise, not only the boss will not make money, but also the enterprise will be in debt. Basically, because the management has the final say, the rule of law management is not effective. For example, foreign employees can leave work without asking about the company. Is Chinese enterprises OK? A lot of boss's private affairs have become employees' work. After work in the evening, maybe the boss will call you back to work overtime. Can the staff not go? Can the boss stop calling? No, because the enterprise is too small, there are too many things, and it's too urgent. The boss is busy, but who doesn't he call you? This is China's national conditions. Foreign employees can shut down after work. Chinese employees can try to shut down. Maybe they will ask you to pack and leave the next day. Therefore, Chinese enterprises should not blindly learn from foreign enterprise management mode, because you are in China, not in foreign countries
Why do small businesses need to be governed by people? Because most small business owners can't afford to pay high wages, most of the talents they recruit are employees who are attracted by their own human relations. People help the boss to work regardless of pay for their emotional relationship. If the boss controls everything and doesn't trust the employees, who else will want to work with you. Therefore, the success of small businesses basically depends on the boss's personality charm in the leaders and influence people, rather than on the system in the managers. Although this kind of management method is unscientific, it is efficient. As a start-up enterprise, the effect is more important than the truth, so the little boss must not superstition what too deep enterprise management, suitable is the best
Why do large enterprises need the rule of law? Because the enterprise is big, there are many people, the boss's personal ability is limited, his language and behavior influence is also limited. If the enterprise does not have an effective management mechanism, then many important documents or important decisions of the enterprise can not be effectively implemented or communicated. There will be a big difference between what the employees do and what the boss thinks. So large enterprises need the rule of law. In addition, the advantage of the rule of law is to solve the unfair phenomenon of enterprises. Let employees compete and grow in a fair, just, open, reasonable and legal market environment. We have the responsibility to bear together, the fault to punish together, the goal to struggle together, the achievement to share together
the problem with most enterprises in China is that the boss does not know under what circumstances the enterprise should be governed by man and under what circumstances the enterprise should be governed by law. Because the development of Chinese enterprises is basically a process from the rule of man to the rule of law. Too early or too late rule of law will be detrimental to the development of enterprises. Therefore, too many enterprises in China either go bankrupt under the rule of man or disappear under the rule of law. Because the rule of man is too loose and the rule of law is too strict and cautious, enterprises often die as soon as they are in charge and mess as soon as they are released. The boss does not know whether the rule of law is good or the rule of man is good. More people lose prestige, less people lose cohesion. If you rule by law too early, you will be alone; If you rule by man too late, you will lose power. Therefore, it is a difficult process for an enterprise to change from rule by man to rule by law. First, the awareness of the boss, second, the determination of the boss, third, the courage of the boss, and at the same time, the opportunity should be grasped. Only in this way can the enterprise effectively transition from the rule of man to the rule of law, so as to make the enterprise develop healthily!
Two statements for reference are found from Babbitt:
-
bitcoin adopts a mathematical contest to determine the time when a transaction arrives at a node, and at the same time to protect this order. In bitcoin system, transactions are sorted by group allocation, Such groups are called blocks (transactions occurring at the same time will be divided into the same block), and then these blocks are linked together, which is called blockchain. Blockchain is used to sort transactions, while the transaction chain tracks and records the change of bitcoin ownership. These blocks are arranged according to time, which is a link. Transactions not in the block are called unconfirmed or unsorted transactions, and any node is about to put a group of unconfirmed transactions into the block, Then broadcast their suggestions about what the next block should be to other nodes in the network
If multiple people generate blocks at the same time (the probability is very small), there will be multiple choices for the next block of the current block. In order to ensure the sequence of block links, the bitcoin system requires each effective block to include the answer to a special mathematical problem, and the computer calculates the text of the whole block, In addition, random guessing based on encrypted hash can be done until an output lower than a certain value is obtained. Hash function can create a short summary from any length of text. This fixed output value is very complex. The only way to find it is random guessing, which is called mining -
when King released PPC last year, it introced checkpoint mechanism to protect against attacks in its early development. This mechanism enables it to resist 51% attacks. " Developers can control a parent node and broadcast "checkpoints" to the whole network, which allows other nodes to agree on certain blocks“ This is actually a [blockchain] continuity warning message, "he said< br />
