1. Cryptofinance focuses on bringing news about bitcoin, cross-border remittance of cryptocurrency, bitcoin information, blockchain projects, etc. for more information, you can pay attention to the official website of cryptofinance and learn more!
2. The era of blockchain 1.0 is the era of digital currency, and the technical basis is:
1. Lianzhuang data block structure based on blocks
2. Network wide shared ledger
3. Asymmetric encryption
4. Source code open source
blockchain 2.0 era technical basis:
1. Smart contract; It is an application in the blockchain system. It is a business logic that can run automatically by coding. It usually has its own token and special development language
2. DAPP: it includes the user's applications, including but not limited to various cryptocurrencies, such as Ethereum wallet
3. Virtual machine: used to execute the compiled code of smart contract. Virtual machine is Turing complete
with the application and deepening of blockchain technology, the era of blockchain 3.0 has come. The mode of blockchain cooperation can be seen from behind the operation of all walks of life. Therefore, blockchain will change the way of human life widely and profoundly, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology
of course, 3.0 came into being with the development of modern cryptography. Today's applied cryptography is the result of cryptography 20 years ago. Therefore, in order to apply blockchain technology to more participation scenarios, especially in Internet economy and other aspects, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed.
3. 1、 Decentralization:
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, independence:
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity:
unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

4. The disappearance should be temporary, just as newspapers are still there after Internet news. However, the new technology will certainly bring some impact or even impact. Blockchain may affect the following 12 instry regions:
1. Banking
as a digital, secure and anti-interference account, blockchain realizes the core function of Banking: the safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking instry. Indeed, UBS, a Swiss company, and baecelays, a British company, are trying to use blockchain technology to improve payment terms. Some other banking companies even said blockchain technology could save $20 billion in intermediate costs

therefore, it is not surprising that banks, as financial service giants, have become the growth force of blockchain venture. Payment and transfer
recently, the world economic forum wrote in Forbes magazine that decentralized payment technology, such as bitcoin, may change the "business structure" of the transfer instry that has not changed for more than 100 years. Blockchain technology can avoid complex systems and create a more direct payment process between the payer and the payee. Whether it is domestic transfer or cross-border transfer, this method has the characteristics of low price, fast speed, and no intermediate fees. Abra (above) is a start-up enterprise that uses blockchain technology for global bitcoin and blockchain based transfer
3. Network security
although the system of blockchain is public, advanced encryption technology is used in the process of data exchange such as verification and transmission. This technology not only ensures the correct source of data, but also ensures that the data will not be intercepted in the intermediate process. If the application of blockchain technology is more extensive, the probability of being attacked by hackers may also decrease. Therefore, people think that blockchain system is more secure than traditional system. One of the reasons why blockchain system can rece the traditional network security risk is that it relieves the demand for middleman
"eliminating middlemen not only reces the potential security risk of hacker attacks, but also reces the possibility of corruption," Goldman Sachs wrote. Guardtime (above) is an Estonian start-up company, which mainly studies instrial network security solutions based on blockchain technology
4. Academic record and academia
holbertson school, a California software skills program, announced that it will use blockchain technology to identify academic credentials. This will ensure the authenticity of holbertson school students in course identification. If more schools adopt such transparent certificates, transcripts and diplomas, academic corruption will be greatly reced, not to mention the labor verification time and paper document cost
5. Elections
at the University of West Virginia, the student union is considering whether to use a voting platform based on blockchain technology to conct school elections. If such a platform is used, students can vote with mobile devices, and the voting results will be included in the public system, so the voting is completely safe. One student who supported this way explained that the vote "can never be modified or deleted by us - programmers, school administrators or students."
Agora voting, a Spanish software project, uses encryption technology to improve the security of online voting. Several of their systems have also been tested in Spain. Recently, the leader of this project proposed several ideas to turn bitcoin and blockchain technology into voting applications, which are far from experimental
6. Car rental and sales
later last year, visa and DocuSign announced a cooperative plan to create specific solutions for car rental by using blockchain technology. In the future, car rental can be completed in three steps of "click, sign and open". The specific operation is: customers choose the car they want to rent, and then the transaction will be uploaded to the public account of the blockchain; Then, the customer signs a lease agreement and an insurance agreement from the driver's seat, and the blockchain will upload the information in real time. It is not hard to imagine that this leasing model may also be applied to the field of car sales and car registration
7. Network communication and Internet of things
IBM and Samsung are working together to realize an idea called adept. Adept uses blockchain technology to build the pillar of decentralized Internet of things. Coindesk said that with adept, the decentralized P2P automatic telemetry system, the blockchain can become a public system for many devices, and there is no need for a central hub to mediate the communication of various devices. After removing the central control system and identifying each other, the devices can automatically communicate with each other, manage software updates, bugs, or energy consumption
other companies are also committed to integrating blockchain technology into the Internet of things platform. For example, filamen, which uses blockchain technology to build a decentralized network for sensor communication, announced that they have obtained US $5 million investment in round a financing, with the participation of Verizon ventures and Samsung ventures
8. Smart contract
a smart contract is actually a computer program that functions on the action of another object. Like ordinary computer programs, intelligent contracts are also an "If then" function, but blockchain technology realizes the automatic filling of these "contracts" without human intervention. This kind of contract may eventually replace the core business of the legal instry, that is, the business of drafting and managing contracts in the commercial and civil fields
for example, mortgage loans can be completed through blockchain technology and automatically executed every year according to the terms of the contract. Ethereum, a crowdfunding platform based on blockchain technology, not only provides decentralized applications, but also provides smart contracts. Some users have married with their smart contracts. Another company, hedgy, received $1.2 million in seed round investment from Tim Draper, Marc Benioff, boost.vc and sand hill angels earlier this year. The company uses smart contracts to build a platform for users to discuss the value of bitcoin
9. Prediction
blockchain technology may shake the whole research, analysis, consulting and prediction instry. Aug, an online crowdfunding platform, hopes to make a profit in a decentralized forecasting platform. The company said it would offer a service that looked like a gaming swap. The whole process will be decentralized, and the AUG platform will not only provide users with sports and stock gambling services, but also provide election and natural disaster gambling services. This idea actually goes beyond sports gambling and creates a "forecasting market"
10. Online music
many musicians are choosing blockchain technology to improve the fairness of online music sharing. Billboard reports that two companies are automatically solving licensing problems by paying artists directly and using smart contracts. Peertracks, which is still in its infancy, wants to create a new music streaming platform where users can pay artists directly without middleman's intervention. Peertracks also hopes to create more direct interaction between artists and users
ujo music, led by entrepreneur Phil Barry, claims that they are rebuilding the music instry on the blockchain. Ujo also hopes to solve the problem of streaming music and artist payment. In addition to streaming music, it is also expected that ujo will be able to better classify the artists and creators behind the songs by using intelligent contracts as the autonomous brain of the song list
11. Travel sharing
Uber and other travel applications seem to be on the opposite side of decentralization. This company is like a deployment center, using its algorithm to control its drivers and their charges. According to the report of blog, Israeli venture LA & # 39; Zooz wants to "go against Uber.". The company invented its own patented digital currency, which, like bitcoin, can be digitally recorded using blockchain technology. Different from the centralized network, users can call in LA & # 39; Find people with similar itinerary on zooz, and then use LA & # 39; Zooz's currency pays the taxi fare. These coins can be used for car hailing in the future. Users can get LA & # 39 as long as they allow the app to track their location; Zooz's digital currency
12. Stock trading
for many years, companies have been trying to simplify the process of stock purchase, sales and trading. Emerging blockchain technology makers believe that they can go beyond the past, realize the automation of the whole process, and improve security and efficiency. Overstock's subsidiary T & # Com wants to use blockchain technology to realize online trading of stocks. Overstock is already using blockchain technology to issue public shares, wired reported. At the same time, chain, a blockchain technology maker (mentioned above), is working with NASDAQ to realize the share trading of private companies through blockchain technology.
5. Blockchain technology has been basically mature, and now it mainly focuses on landing applications
on the ground, there will be different solutions according to different instry needs
for example, in the financial instry, relevant financial technology companies have studied and applied it for a long time. Recently, there is a one account chain platform, which is released by Ping An's financial one account link company. It is the solution of blockchain in the financial instry. According to the introction, it has broken through the bottleneck in the implementation process.
6. Yes, blockchain technology is based on big data. Only if big data is big enough and there are enough categories, blockchain technology will become more and more mature
at present, the application of blockchain has extended to the Internet of things, intelligent manufacturing, supply chain management, digital asset trading and other fields. According to the analysis of Chongqing jinwowo group, the development and application of big data technology and blockchain technology have a profound impact on the organizational structure of the society, the governance mode of the country, the decision-making structure of the enterprise, the business strategy of the business and the personal lifestyle.
7. Hello, it is reported that the public platform of SMIC blockchain in Changsha is going to launch blockchain + human resource services recently. We can look forward to how they can do blockchain + human resource applications.

Chinese Name: Thomas Alva Edison
English Name: Thomas Alva Edison
a world-famous American electrician and inventor, known as the "king of invention in the world", has made more than 1000 inventions in his life. In addition to his invention and contribution in phonograph, electric lamp, telephone, telegraph, film and other fields, he also has many famous creations and insights in mining, construction, chemical instry and other fields. Edison had about 2000 inventions in his life, which made great contributions to the civilization and progress of mankind
Edison was also a great entrepreneur. In 1879, Edison founded "Edison Electric lighting company". In 1880, incandescent lamps went on sale. In 1890, Edison had established its various businesses into Edison General Electric Company. In 1891, Edison's thin filament and high purity blank incandescent bulb were patented. In 1892, Tom was born; Houston incorporated with Edison power lighting to form general electric company. General Electric began to dominate the electric field for a century< Edison was born on February 11, 1847 in Milan, Ohio, a small town in the Midwest of the United States. His father is a descendant of the Dutch, and his mother, a former primary school teacher, is a descendant of the Scots. When Edison was 7 years old, his father lost money in the tile business and moved his family to Fort gratiott, a northern suburb of Huron, Michigan. Soon after he moved here, Edison suffered from scarlet fever, which is believed to be the cause of his deafness. Edison went to school at the age of 8, but after only three months of reading, he was expelled from school by his teacher as an "imbecile". From then on, his mother was his "tutor.". Because of his mother's good ecation method, he became interested in reading“ He not only read extensively, but also read everything at a glance. At the age of 8, he read the works of Shakespeare and Dickens, the most important playwrights in the British Renaissance, and many important historical books. At the age of 9, he could quickly read difficult books, such as nature and experimental philosophy by Parker. When I was 10 years old, I loved chemistry. At the age of 11, he experimented with his first telegram. In order to make money to buy chemicals and equipment, he began to work. At the age of 12, he got a job selling newspapers on the train, traveling between Port Huron and Detroit, Michigan. He sells newspapers while doing fruit and vegetable business. Whenever he has time, he goes to the library to read. He bought an old printing press and began to publish his weekly, the herald, the first of which was printed on the train. With the money he earned, he set up a chemical laboratory on the luggage cart. Unfortunately, once a chemical caught fire and he and his equipment were thrown out of the car. Another time, while Edison was trying to get on a freight train, a conctor grabbed his ears to help him get on. This action led Edison to be deaf for life< In August 1862, Edison rescued a boy who was about to die on the train track with great courage. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it. From then on, Edison had a relationship with this mysterious new world of electricity and embarked on the journey of science< In 1863, Edison served as the telegrapher of Stratford junction station on the main line railway. From 1864 to 1867, he worked as a telegraph operator in the central and western regions and lived a life similar to wandering. Footprints, including Stratford, Adrian, Fort Wayne, Indianapolis, Cincinnati, Nashville, Tennessee, Memphis, Louisville, Huron and other places< In 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first patent for invention. This is an automatic voting device. Edison thought the device would speed up the work of Congress, and it would be popular. However, one congressman told him that they had no intention of speeding up the agenda and that sometimes voting slowly was out of political need. From then on, Edison decided not to invent anything that people didn't need< In early June 1869, he came to New York to look for a job. While he was waiting for a call in an agent's office, a telegraph broke down. Edison was the only one there who could fix the telegraph, so he got a better job than he expected. In October, he and Popper set up a "Popper Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the "Edison universal press". He dedicated the press to the manager of a big Wall Street company. He wanted to ask for $5000, but he didn't have the courage to say it. So he asked the manager to give him a price, and the manager gave him $40000<

Edison used the money to build a factory on ward street in Newark, New Jersey, which specializes in manufacturing all kinds of electrical machinery. He works all night. He trained a lot of capable assistants. At the same time, he also ran into the diligent Mary, his first bride in the future. In Newark, he made such inventions as wax paper and mimeograph. From 1872 to 1875, Edison invented the double Telegraph and quadruple telegraph, and helped others build the world's first English typewriter< In the spring of 1876, Edison moved to "Monroe Park" in New Jersey. He built the first "invention factory" here, which "marks the beginning of collective research". In 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented his favorite project, the phonograph. Telephone and Telegraph "is a revolution to expand human sensory function"; Gramophone is one of the three great inventions that changed people's lives. "From the perspective of invention imagination, this is his extremely important invention achievement.". By this time, people called him "the magician of Monroe Park"< When Edison invented the phonograph, he finally made a breakthrough in the research of electric lamp after numerous failures. On October 22, 1879, Edison lit the first electric lamp with wide practical value. In order to extend the life of the filament, he retested, and tried out more than 6000 kinds of fiber materials before finding a new luminous body, Japanese bamboo silk, which lasted for more than 1000 hours, and achieved a rable purpose. In a way, this invention is the highest achievement of Edison's life. Then he created a power supply system that allowed distant lamps to be distributed from a central power station, a major technological achievement
his first discovery in pure science appeared in 1883. When experimenting with electric lamps, he observed what he called the Edison effect: an electric charge in the lighted bulb passes through space from the hot filament to the cold plate. Edison patented the discovery in 1884, but did not study it further. Other scientists used the Edison effect to develop the electronic instry, especially radio and television
Edison tried to do what the phonograph did for the ear for the eye, and the film camera was born here. Using a new Celluloid film invented by George Eastman, he took a series of photos and projected them onto the screen quickly and continuously, creating the illusion of movement. He first experimented with films in the laboratory in 1889 and patented them in 1891. In 1903, his company proced the first feature film "train robbery". Edison did a lot of work for the formation and standardization of the film instry< After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies to make procts and promote sales for his various inventions; These companies later merged into Edison General Electric Company, later known as general electric company. Since then, his interest has shifted to fluorimetry, ore crushers, magnetic separation of iron, batteries and railway signaling devices
ring World War I, he developed torpedo mechanisms, flamethrowers and underwater periscopes< On October 21, 1929, on the 50th anniversary of the invention of electric light, people held a grand celebration for Edison. Famous scientists such as Einstein of Germany and Madame Curie of France congratulated him one after another. Unfortunately, at this celebration, when Edison delivered his reply, he suddenly fainted e to excessive excitement. From then on, his health went from bad to worse. On October 18, 1931, the scientist who had made great contributions to mankind died of illness at the age of 84
Edison's ecation level is very low, but his contribution to mankind is so great. What's the "secret" here? In addition to a curious heart, he has an instinct to test himself, that is, he has the infinite energy and bold spirit of extraordinary hard work. When someone called Edison a "genius", he explained: "genius is one percent inspiration and ninety-nine percent perspiration." In the "invention factory", he organized many people of different professions, including more than 100 scientists, engineers, technicians and workers. Many of Edison's major inventions were successful thanks to this collective force. His achievements are mainly e to his hard work and creative ability as well as the collective strength. In addition, his wife also played a very important role< In August 1862, Edison rescued a boy who was about to die on the track of a train. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it. From then on, Edison had a relationship with this mysterious new world of electricity and embarked on the journey of science< In 1863, Edison worked as a telegrapher at Stratford junction station of the main line railway. From 1864 to 1867, he worked as a telegraph operator in the central and western regions and lived a life similar to wandering. The footprints include Stratford, Adrian, Fort Wayne, Indianapolis, Connecticut, Nashville, Tennessee, Memphis, Louisville and Huron< In 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first patent for invention. This is an automatic voting device. Edison thought the device would speed up the work of Congress, and it would be popular. However, one congressman told him that they had no intention of speeding up the agenda and that sometimes voting slowly was out of political need. From then on, Edison decided not to invent anything that people didn't need< In early June 1869, he came to New York to look for a job. While he was waiting for a call in an agent's office, a telegraph broke down. Edison was the only one there who could fix the telegraph, so he got a better job than he expected. In October, he and Popper set up a "Popper Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the Edison general seal
9. There is a misunderstanding here. We all think that the technology is advanced and difficult to understand. It is difficult for us to understand the technology of non professional technicians, let alone use it to judge whether a project is worth investing or not. In fact, the technology is not so difficult to understand. The underlying technology of the blockchain is more of a kind of mathematical logic, which takes time to understand. However, it does not need the programming foundation, and ordinary investors can understand it. We can all make value investment by looking at technology.
