Does digital currency still need watermark

1.

Basic routine: the "trading market" of MLM digital currency is basically controlled by specific institutions. In order to attract investors' investment in the early stage, the currency price may be very high. Once the time is ripe, it will be sold intensively, and the price will plummet, and the investors will lose all their money

There are three characteristics of digital money MLM:

1. Digital money is a real proct, and it is highly packaged

2. The participants can get a head pulling reward, and the prize is the digital currency itself

3. Digital currency will appreciate with the increase of participants in the scam. In the cycle of digital currency appreciation, the number of participants who can obtain digital currency will also increase, and the participants, including the lowest level participants, will also gain, but in the cycle of devaluation, the bottom level participants often lose a lot

in 2017, the Internet Finance Association of Jiangsu Province issued the "internet pyramid selling identification guide", which named 26 so-called digital currencies as illegal pyramid selling projects covered or suspected to be covered with digital currency. They are: treasure money, Baichuan money, SMI, MBI, mark money, Diablo money, mmm, Fuda compound wealth management, carat money, V treasure, Vicat money, petroleum money, Huaqiang money, CB aiib Hong Kong Group, Yuansheng, Morgan money, beta money, WorldCom, u money, Jubao, 21st century fox, Wanxi wealth management, Wanfu money, Wuxing money, Yi money, Zhonghua money, etc

extended materials:

five ways to distinguish whether digital currency is pyramid selling currency:

1. Issuance mode

virtual currency does not rely on specific monetary institutions. It is proced by a large number of calculations according to specific algorithms, and is a decentralized issuance mode. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head

2. Transaction mode

virtual currency is a kind of sporadic transaction spontaneously formed in the market, which is graally completed by a third party establishing an exchange after the scale is formed. The MLM currency is issued by an institution and traded on its own platform

3. Implementation method

virtual currency itself is an open source program, which is maintained in GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency

4, whether to give the source code link

General decentralized digital currency will give the source code link in the prominent position of the official website, so as to show the operation mechanism of the monetary system openly and transparently. The MLM currency focuses on the transaction process of recharge purchase, but does not mention its operation mechanism. Even the website does not have the link address of the source code

5, whether the official website starts with HTTPS

generally, the addresses of the official website and trading website of decentralized digital currency start with HTTPS, and the purpose is that this kind of website can well protect the user's data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS

2. Digital currency is a kind of virtual currency, so the pictures of digital currency are virtual. Unlike RMB, it really exists. Specific digital currency pictures can be viewed at bitnet exchange.

3.

With & lt; Digital currency;, People will continue to use WeChat and Alipay. The emergence of digital money will not affect WeChat and Alipay. The reasons are as follows:

first: the popularity of digital currency takes time. The

digital currency has begun to promote, but it still takes time to fully popularize it. After all, digital currency is a new way of payment, consumers need to fully accept it. Alipay is able to get users to trust and accept, and it has also been a long time. WeChat also has the user base to achieve the current popularity, but digital money has no such foundation. P>

but Alipay and WeChat do not have counterfeit software. From this point of view, at least WeChat and Alipay's security is guaranteed. Moreover, it is not easy for consumers to change their habits, especially for the same kind of things. There is no need to change them at all. In theory, digital money is just like paper money. Alipay and WeChat are only third party payment platforms, but there is not much difference as long as they can complete the payment. p>

4. Digital currency cheated, why not catch this? At present, the country is the fastest on digital currency, and there is no complete qualitative analysis, so it has no relevant laws

At present, there are two kinds of watermarks on banknote paper in China: fixed watermarks and full page watermarks. The images of Guowei in 1953, Tiananmen in 1965, farmers in 1980, workers in 50, Mao Zedong in 100 and Mao Zedong in 1999 are fixed watermarks; In the 1980 version of 1-5 yuan coupon, there are four continuous watermarks on the whole banknote. There is no fixed position, so it is called full version watermark. The application of watermark technology on banknotes can effectively prevent counterfeit banknotes

Compared with the normal paper, the fiber density of the dark part of the watermark is higher, and the fiber density of the bright part is lower. Therefore, the real watermark effect can only be obtained when making paper, and forgery is difficult. Some counterfeiters use embossing, whitewashing or printing to create a false watermark that seems to have light and shade. With a little knowledge of the watermark, it is easy to identify it

for the first set of RMB banknote paper in China, except for a few large denomination tickets with ripple, five pointed star or English alphabet watermark, most of the tickets have no watermark. In 1953, the second set of RMB was printed. Most of the banknote paper was made by the Soviet Union. Three kinds of banknote paper were made. One dime, two dime, five dime and one yuan banknotes were hollow five pointed star full page watermark paper, two yuan, three yuan and five yuan banknotes were solid five pointed star full page watermark, and ten yuan banknotes were fixed watermark of the national emblem of the people's Republic of China. The quality of banknote paper in this period has been tested and improved to a certain extent compared with that before the founding of the people's Republic of China. With the development of China's national economy and the improvement of proction level, with the approval of the higher authorities, it is decided to develop China's own special watermark banknote paper from 1957, which is a new work. The development of watermark banknote paper is a highly technical and artistic work. The technological requirements of design, sculpture, plate making and paper making are very high. In the process of research and development, experts from the Central Academy of fine arts and the Central Academy of Arts and crafts were employed as teachers. At the same time, the whole process of papermaking was studied. A large number of documents at home and abroad were carefully searched. After more than three years of research and repeated experiments, the five pointed star banknote mixed full version watermark banknote paper was successfully trial proced in the first half of 1960, In the same year, we successfully trial proced the national flag five pointed star full version watermark banknote paper. Later, we worked hard to develop the Tiananmen fixed watermark banknote paper with high denomination and high quality of 10 yuan in the second year. In just over three years, we have successfully developed more than ten kinds of banknote watermark paper, which is ready for printing the third set of RMB. The printing of the third set of RMB is in a difficult period of natural disasters, but for the first time, all the new banknotes have adopted the watermark banknote paper of high standard and high quality developed by ourselves. Since then, the history of China's long dependence on imported banknote paper has ended

After the 1960s, especially after the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, on the basis of further learning foreign advanced technology, we reformed and innovated, making our watermark proction technology have a new improvement. Since April 27, 1987, the fourth set of new version of RMB has been issued one after another, showing a new look in front of the Chinese people. In addition to 1 yuan, 2 yuan and 5 yuan, 10 yuan, 50 yuan and 100 yuan banknotes are made of highly difficult head portraits of farmers in Northern Shaanxi, steel-making workers and Mao Zedong, which proves that China's banknote watermark paper proction has entered the ranks of advanced countries in the world and will play an important role in ensuring China's currency stability

Anti counterfeiting methods of digital RMB:

1. Observe the number of glossy and variable denomination

on the basis of the current fifth set of anti-counterfeiting technology for RMB banknotes, the new version of 50 yuan, 20 yuan and 10 yuan banknotes has added the glorious variable denomination number. Guangcai Guangbian technology is recognized as an advanced anti-counterfeiting technology in the field of international banknote printing, which is easy to identify by the public

the fifth set of RMB 50 yuan, 20 yuan and 10 yuan banknotes of the 2019 edition is printed with the variable denomination number of Guangcai light in the middle of the face. The color of the denomination number changes when the viewing angle of the banknote is changed, and a bright light band can be seen rolling up and down. Take the new version of 50 yuan as an example. With the change of viewing angle, the color of the denomination number "50" will alternate between green and blue

2

the safety line of light variable hollowed out windows has the characteristics of color change and hollowed out text, which is easy to be recognized by the public, and is a common public anti-counterfeiting feature

the 2019 version of 50 yuan banknote adopts dynamic light to change the safety line of hollowed out window, change the viewing angle of banknote, the color of safety line changes between red and green, and the bright light band rolls up and down; Light transmission observation showed that "&" 165; 50”

the safety line of 20 yuan and 10 yuan banknotes in 2019 version is similar to that of 100 yuan banknotes in 2015 version. The color of safety line changes between red and green by changing the viewing angle of banknotes; Through light observation, 20 yuan note can be seen "&" 165; 20 ", 10 yuan note can be seen" &# 165; 10”

3. Observe the watermark

the 2019 version of 50 yuan, 20 yuan and 10 yuan banknotes significantly improves the watermark clarity and level effect. The watermark of the portrait is located in the blank space on the left side of the face of the ticket, and the head of Mao Zedong can be seen through light transmission. The definition of human image watermark is obviously improved, and the level is richer. The white watermark is located below the horizontal number on the front of the ticket, and the watermark denomination can be seen through light transmission observation. It is worth mentioning that the new version of 1 yuan note added white watermark

the fifth set of RMB in 2019 edition adjusts the left horizontal number pattern and adds vertical number, which can effectively prevent the alteration of banknotes. The crown and the first two digits of the left horizontal number are dark red, and the last six digits are black. On the right side of the vertical number, the crown words and numbers are blue

development history of digital RMB:

in 2014, the people's Bank of China set up a special team to carry out special research on issues such as digital currency issuance framework, key technologies, Issuance and circulation environment and relevant international experience

at the end of 2017, the people's Bank of China organized some commercial banks and relevant institutions to jointly develop the digital RMB system (DC / EP). DC / EP has basically completed the top-level design, standard formulation, function research and development, joint debugging and testing under the premise of adhering to double-layer operation, cash (M0) substitution and controllable anonymity

on April 19, 2020, the relevant person in charge of the digital currency Research Institute of the people's Bank of China said that the research and development of digital RMB is steadily advancing, and the internal closed pilot tests are carried out in Shenzhen, Suzhou, xiong'an New District, Cheng and the future Winter Olympics scenes in China, so as to continuously optimize and improve the functions

in May 2020, Yi Gang, President of the people's Bank of China, said that the current pilot test of digital RMB is only a routine work in the process of research and development, which does not mean that the digital RMB will be officially launched, and there is no timetable when it will be officially launched

on August 14, 2020, the Ministry of Commerce of the people's Republic of China issued the overall plan for comprehensively deepening the pilot project of innovation and development of service trade. In the part of "tasks, specific measures and division of responsibilities for comprehensively deepening the pilot project of innovation and development of service trade", the Ministry of Commerce of the people's Republic of China proposed to carry out digital RMB pilot projects in Beijing Tianjin Hebei, the Yangtze River Delta, Guangdong, Hong Kong, Macao and other qualified pilot areas in central and Western China

the people's Bank of China formulates policy safeguard measures; First, Shenzhen, Cheng, Suzhou, xiong'an new area and other relevant departments of the future Winter Olympic Games scene will assist in the promotion, and then expand to other regions as appropriate

on October 8, 2020, Shenzhen Internet Information Office of Guangdong Province of China announced that in order to promote the construction of Guangdong, Hong Kong and Macao Dawan District, and in combination with the local consumption promotion policy, Shenzhen Municipal People's government and the people's Bank of China recently launched a pilot project of digital RMB red envelope [4]. The red envelope was issued in the form of "lottery", and the lottery registration channel was officially opened on the 9th [9]

7. Edison (1847-1931) was a famous American inventor. He was diligent, studious, thoughtful and hardworking all his life. At the age of 75, he also went to the laboratory on time every day to check in for work. For decades, he worked for more than ten hours every day and read for three to five hours in his study at night. If we calculate by the activity time of ordinary people's life, his life has been doubled. So Edison, on his 79th birthday, said to people with pride, I'm 135 years old. He lived to be 84 years old. He made 1100 inventions in his life. His greatest contributions were the invention of phonograph and automatic telegraph, the experiment and improvement of incandescent lamp and telephone. Edison began to study electric lamps in his early twenties. It took him more than 10 years. He used thousands of different materials, such as bamboo, cotton, graphite, tantalum, and so on, as filament materials to carry out experiments. He often reached the top of the sky. Once, he and his assistants worked continuously for five days and nights. In 1879, Edison used carbon filament as incandescent filament and ignited it for 40 hours. Because the surface of carbon fiber is porous, brittle and low strength. It was soon replaced by tungsten wire< In 1883, Edison discovered the phenomenon of hot electron emission, also known as "Edison effect", that is, some electrons or ions near the metal surface get enough kinetic energy e to the high temperature, so as to overcome the binding of the surface and escape from the metal. Edison effect is very important for the operation of all vacuum tubes. The cathode, as the emitting surface, is often coated with alkaline earth metal oxide to facilitate electron emission, and heated by electric current to maintain high temperature< In 1900, Edison invented the iron nickel battery, which is an alkaline battery with electromotive force of about 1.3-1.4 V, long service life and low efficiency.

8. Go language has not shown a clear direction since its appearance. Google employees call it an "experimental language", saying that it tries to integrate the development speed of dynamic languages such as python with the performance and security of compiled languages such as C or C + +. A supporter of go language summarizes that go language is as follows: simple, fast, safe, concurrent, happy programming, open source; But go language lacks direction and the attempt of its "synthesizer" will easily lead to its failure to learn from cats and dogs, and become a four unlike. Nevertheless, the editors still think that go language has great potential: many developers are interested in it - not only its original designers have a strong lineup, but also the people involved in modifying the source code. This is likely to help go language find its own direction and open up a new direction of system programming.
