Original tribe of blockchain

1. If the subject does not mean literally, it should be used in the stock market or finance

cutting leeks generally means that part of the capital leaves at a loss and another part of the emerging capital enters the market, just like cutting leeks, cutting one crop for a long time. We can understand it as a capital shuffle in the stock market or finance

so you can use financial shuffle or directly use reshuffle

to collect wool, which refers to the behavior of using various preferential information to realize personal small interests

at present, there should not be a very consistent statement, but it can also be translated as "bonus getting" or "deal getting". The people who collect wool can also be translated as "bonus Hunter"
in recent years, the word "collecting wool" has become more and more popular. What does it mean? How to operate

the so-called "wool collecting" refers to purchasing goods at a price far below the market price, or even 0 yuan. The question is, how can we do it

for example, the current online shopping platform has a lot of proct discount activities are superimposed

1. For example, a 399 proct can also receive a 399-150 coupon when participating in the full rection of 399-200. What's the final price? 399-200-150 = 49, that is to say, you can buy 399 items with 49 yuan

2. For a 1000 yuan proct, you can get 1000-300 platform coupons, 1000-200 store coupons, and a 20% discount. What's the price?

blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

extended data:

the evolution mode of blockchain is as follows:

& 9642; Blockchain 1.0 - digital currency

▪ Blockchain 2.0 - digital assets and smart contracts

▪ Blockchain 3.0 - Implementation of distributed applications in various instries

blockchain features:

1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system

2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work

The information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

The origin of Wall Street in the United States is that the Dutch built a section of wooden wall, which was later demolished and became Wall Street

at first, New York was a Dutch colony, a settlement of Dutch immigrants, which was called New Amsterdam at that time

In 1640, small plots of land in the New Amsterdam colony were separated by pickets and fences. In order to effectively control the slaves from Africa, Peter steiversant, a representative of the Dutch West India Company, led the immigrant groups from the Netherlands to build stronger fences. The fence was strengthened into a 3.65-meter (12 foot) high wall of mud and wood

Since then, in order to resist the Indian tribes, the New England colonists and the British, the wooden wall has been graally expanded and strengthened. In 1664, New Amsterdam was captured by the British, and the city was transferred from the Dutch to the British. In 1685, surveyors marked a road along the original fence, wall street

In 1699, the British demolished the wall. The name of Wall Street has been preserved

Wall Street is a transliteration of "Wall Street"

the childhood of Wall Street is from 1949 to the end of the 19th century. The rapid development of New York and the rise of financial instry in New York have a lot to do with the Dutch business spirit. Although the early sprouting of capitalism began in Renaissance Italy, the real capitalism was graally perfected in Holland in the middle of the 17th century

at that time, the Netherlands formed a very complete financial system, including banks, stock exchanges, credit, insurance, limited liability companies, etc. the development of the financial system gave birth to the Dutch economic take-off, making this small European country once one of the most powerful countries in the world. When the Dutch immigrated to North America, they brought the business spirit of capitalism to New Amsterdam

1. Since 1974, Zhao Dayu, a famous football player, failed to apply for the provincial professional football team several times because of his short stature. His repeated failures made him feel confused and frustrated

at this time, Zhao Dayu's father is even more unhappy. Which parents don't want their children to go out and cast their children? However, he deeply understands that it is terrible for a person to lose opportunities, but what is more terrible is to lose faith. What his son needs at this moment is encouragement and support

therefore, he tried to restrain his feelings. In order not to let his son lose confidence and give up his efforts, he told his son the story of "lying on the staff and tasting the gall", and encouraged his son to bite his teeth, not to admit defeat easily, and to be a man of backbone

he also introced the story of Hu Denghui, a football player, to his son. Although he was small, because he played very well, he still entered the national team. He also took his son to see a Guangdong Star, and asked him to introce the unique skills of small men playing big men. He tried every means to make his son establish such a belief: "as long as you are better than others, someone will come."

with the encouragement and support of his father, Zhao Dayu regained his confidence and never gave up his efforts. Hard work, and finally won the initial harvest. In 1975, Zhao Dayu entered the Guangzhou team and participated in the National Youth Championship

But at this time, my father was hospitalized because of illness. In the face of such sudden changes, the father still did not give up the desire to let his son continue to work hard. He asked his son to keep faith, continue to fight, do not delay the training because of himself, this is his biggest and only wish as a father

In the 2000 Premier League, Everton played West Ham. At the last minute, the score was still 1-1. At this time, Everton goalkeeper suddenly injured when throwing the ball, the ball rolled to the opponent's player di Canio side, he was only 10 meters away from the goal, just a light kick can kick into the "undefended" goal

At the critical moment, di Canio didn't play the decisive role, but bent down to hold the ball firmly in his arms. The whole football field was silent for a moment, and the applause was thunderous

However, who would have thought that 10 years ago, Messi almost ended his football career because of dwarfism. Like other children in his hometown of Rosario, Messi has loved football since childhood; But like his family, Messi was born short and thin

although he has always been the best player in the junior team of Newell's old boys, Messi was only 3500px at the age of 12. According to the doctor's examination, he suffered from congenital dwarfism and stopped growing at the age of 11

Messi's dwarfism is not incurable, but the monthly cost of injecting growth hormone is as high as $900. The old man of Newell, the parent team, is not willing to pay for a child whose future is uncertain. He once coveted Messi's river bed, and when he learned of his stubborn disease, he gave up the idea of poaching

"I remember and will never forget the day when I got the diagnosis. It was very cold at that time. We were in the street. Messi didn't have any expression and was very calm. I know he knows better than anyone that there is no ability for him to be treated at home

father Jorge recalled, "as a father, I know that Messi's illness is e to malnutrition. Argentina is rich in the best beef in the world and has the best cheese in the world, but that doesn't belong to us

Macy grew up eating potatoes and carrots and playing football after drinking soup without oil foam. He never complains. No one knows that better than me when he is young. "

In September 2000, he joined the Barcelona youth team at the age of 13 and height of 140cm with his superb skills. In the first game, with his skillful footwork and excellent dribbling ability, he won over thousands of spectators in the stands

in the stands, there were thunderous applause and screams! Father was even more excited to tears. However, after the surprise, the father's heart is boundless desolation and despair. The height of 140 cm doomed my son to have nothing to do with football. The more perfect his footwork is, the more regret and pain he brings to his father

4. Lovely buckteeth and skillful football skills may be the impression of many fans on Ronaldinho. Now that Ronaldinho is getting older and his form is declining, people graally forget about the post-80s football superstar

Therefore, it is necessary for the post-80s inspirational network to review the brilliant achievements of Ronaldinho in this article: he won the World Footballer of the year in 2004 and 2005 for two consecutive years; In 2005, he was elected European Footballer of the year and became the best player of the first international professional football association in the same year

Ronaldinho's football career is absolutely a classic inspirational model of the post-80s generation: on March 21, 1980, Ronaldinho was born in a family with a strong football tradition in Porto Alegre, a small city in Brazil. Just like the growth process of many Brazilian international players, Ronaldinho's family has an unusual passion for football

my father used to be a football player, my mother was a fan, and my brother was also a football player. Influenced by his family, Ronaldinho began to play football when he was very young. He even played with his dog

Luo said: "as soon as my mother comes to Sunday, she will take her homemade Bento and go to the stadium to enjoy football with us. When I was a child, I always felt like a happy child. " Ronaldinho's happiest life every day is to go to the football field, and from the slum cottage to the stadium is Ronaldinho's most common route

The family was not rich when he was a child. When his father was 8 years old, his mother shouldered the burden of the family life. "Overnight, we didn't know what to do, the pillar of the family was gone, and the future was gone

at this time, my brother woke me up and said that I had the responsibility to make the family life better. " Xiao Luo, who grew up overnight, completely changed his temper. He no longer relies on cleverness to show off his footwork. He has a sense of crisis to practice every skill well

At this time, Ronaldinho is looking forward to following his brother Robert Assis's footsteps to achieve success. His brother played in Porto Alegre's Gremio and was selected for the Brazilian national team

In 1997, the World Youth Championship held in Egypt became a brilliant stage for Ronaldinho, whose name made the headlines. He showed his skill in that cup and defeated Ghana 2-1 in the final

Ronaldinho, who scored seven goals in this cup, was named the best player and became the best shooter of the champion team, which was the first best in his football career. His name was known all over the world for a while, and this success opened a new chapter in Ronaldinho's career

after Ronaldo, Ronaldinho has been hailed as another outstanding Brazilian new star. "The honor made me more confident and opened the door to the world's top football clubs," Ronaldinho recalled

In 1998, Ronaldinho signed his first contract with Gremio. He took the first step towards success, which soon earned him a place in the national team

when Ronaldinho entered the Brazil national team and scored the first goal, his celebration was to point his finger to the sky, look up for a long time, as if to tell his father's spirit in heaven: your dream has finally come true. Since then, every time Ronaldinho points to the sky after scoring, it means that he wants to dedicate the goal to his father

Ronaldinho's eye-catching performance in international competitions has attracted the attention of many European giants. Different from many famous Brazilian international players who started from low-level or minor league matches in Europe, Ronaldinho has only played for Gremio, Paris Saint Germain, Barcelona and AC Milan

in Gremio, he was already compared with Pele. Maradona said that Ronaldinho is more flexible than Pele, more agile than Zico and more practical than Denilson

for comparison, it is natural that everyone has their own opinions. However, no one can deny Ronaldinho's talent and efforts. Ronaldinho's superb skills have been praised by many of his predecessors. Maradona called Ronaldinho a "football artist"

On July 19, 2003, Ronaldinho joined Barcelona for $28 million. When Laporta accompanied him to the stadium, about 30000 fans cheered their long admired idols in the stands, and all the jerseys printed with Ronaldinho's name sold out

afterwards, Ronaldinho enjoyed himself in this top European club, and the Brazilian began to show his fists in this fertile land of football. His arrival also injected new vitality into the sick Barcelona. In the match with Sevilla, Ronaldinho took the ball from the back field to the front 25 meters, which was his debut in La Liga

Ronaldinho scored a hat trick in the 8-0 UEFA Cup victory over Slovakia's puchev. In his first season, Ronaldinho helped Barca not lose in 17 league matches in a row, and finally won the second place in the league and the chance to advance directly to the Champions League

since 2006, e to the long-term nightclub life, the state has dropped sharply, until the 09-10 season finally began to recover, the 11 season performance was brilliant and returned to the Brazilian national team, we look forward to more surprises from Ronaldinho

Didier Drogba is undoubtedly one of the greatest players in the world. This young Ivorian, who was elected "African Footballer of the year" in 2006, never forgets to call for peace with the charm of football, and has made the world look up to him with his unique bravery again and again

On December 13, 2013, Drogba represented Galatasaray in the Turkish Football Super League, which coincided with the death of former South African President Mandela

in the middle of the match, Drogba suddenly took off his shirt and revealed a T-shirt printed in memory of Mandela, which said: "thank you, Mandela!" His move is a clear violation of FIFA's stipulation that "indivials are not allowed to express their political inclination ring the competition"

Then, the Disciplinary Committee of the Turkish Football Association announced that Drogba would be given a warning. As a result, Drogba has become the only star in the world who bravely salutes and mourns Mandela on the field

In response, Drogba said: "for peace, I don't care how severe punishment I am given. I have to use my own way to send off and mourn the old man who has been fighting for the abolition of racial discrimination all his life, so as to express my highest respect for him."

This is not the first time Drogba has made a special move. On October 8, 2005, Didier Drogba's Ivory Coast National team beat Sudan 3-1 in the last group match of the world cup preliminaries to get the ticket to enter the world cup

as the captain, Drogba is very clear that his motherland is in the civil war caused by the mutiny at this time. Therefore, he specially invited the camera reporter of the Ivorian national TV station to the dressing room and suddenly fell on his knees

In terms of form, money can be divided into physical money and formal money according to the commodity value of money. Physical money itself is a kind of special commodity, including the amount of value, such as sheep, precious metals, etc; However, formal money itself has no value quantity, value is contracted, only contractual value

extended data:

the generation of money:

the function of money as a means of payment is generated to meet the needs of the development of commodity proction and commodity exchange. Because merchandise transactions were initially paid for in cash. However, because the proction time of various commodities is different, the sales time is also different

e to the difference in proction and sales time, some commodity procers need to buy some goods on credit from other commodity procers before their own goods are proced or sold. The transfer of goods is separated from the realization of price in time, that is, the phenomenon of buying on credit. When the debt is paid off on the agreed date after the credit purchase, the currency performs the function of payment means

As a means of payment, money was first caused by the purchase of goods on credit and prepayment, and then graally extended to the field of commodity circulation. In the capitalist society with developed commodity exchange and credit, it has increasingly become a common way of transaction
