The purpose of inventing blockchain
The 2018 global media blockchain summit was held in the financial hall of the Hong Kong Stock Exchange on the 19th. Focusing on the development prospects and instry trends of blockchain, a number of participating media made suggestions on deepening the cooperation of media blockchain and promoting the healthy development of the instry, and jointly announced the establishment of the global media blockchain alliance
According to the introction, the alliance will provide an open access mechanism for media members to integrate resources and build a reliable media blockchain platform. At the meeting, the global media blockchain alliance released the "Hong Kong initiative", advocating the media to disseminate advanced ideas, encourage ecological innovation, and continuously provide high-grade and high-quality information and services in the information dissemination of blockchain Yu Guoming, executive director of School of Journalism and communication of Beijing Normal University, pointed out at the summit that only through full development of media blockchain can a more sound and good media ecology be formed. Mainstream media should consciously assume social responsibility in the development of media blockchain and become organizers and builders of promoting technological progress and business innovationDing Laibin, Secretary General of global media blockchain alliance, said that blockchain technology is expected to bring new social changes and needs to take care of its healthy development. In terms of public opinion supervision in the field of blockchain, the media should give full play to its role, tap instry value, crack down on instry fraud, and make good contributions to the development of blockchain instry

blockchain is the underlying system of distributed ledger in bitcoin. Bitcoin ledgers are built in a distributed and spontaneous way. Anyone can generate new currency blocks by performing specific cryptographic calculations, so as to obtain a digital "currency" that can be used for transactions. Bitcoin's impact on the world monetary system can be said to be subversive, which is also an important reason why it has attracted a lot of people's strong attention since it came out. After that, there were dozens of similar electronic currencies such as
"lightcoin". The abstract extraction of distributed digital currency technology from bitcoin forms a "blockchain" technology, which can be used in more fields
the basic idea of blockchain is to establish a network-based public ledger (data block), each block contains the information of a network transaction. All the participating users in the network work together to keep accounts and check accounts. All the data are open and transparent, and can be used to verify the effectiveness of the information. In this way, the authenticity and non tamperability of information can be guaranteed at the technical level without the central server as the trust intermediary
the significance of blockchain lies in "decentralization", which can fundamentally solve the fraud and rent-seeking phenomenon in value exchange and transfer by building a more reliable network system. With the popularization of blockchain technology, the digital economy will be more authentic, and the economic society will become more fair and transparent
not only digital currency, but also blockchain technology is infiltrating into more innovative fields.
virtual digital currency such as bitcoin is just an application scenario of blockchain technology. Theoretically speaking, based on the characteristics of blockchain technology, human beings can create a very rich form of services and procts, such as finance, government, enterprises, etc There are a large number of scenarios suitable for blockchain technology in cross instry and other fields, with broad prospects. At present, many countries around the world have started the research of blockchain technology, and a series of instry organizations and alliances have been established. However, as blockchain technology is a brand-new technology, which subverts the traditional centralized mode, major institutions are still in the research stage, with only a small number of actual projects landing, and the great development of the instry has just begun
now, blockchain economy is on the eve of outbreak. The exploration of financial instry is ahead of others, while the application of other instries is developing rapidly. The obvious advantage of blockchain instry application is to optimize business process, rece operation cost and improve collaborative efficiency. This advantage has been graally reflected in financial services, Internet of things, public services, social welfare and supply chain management
as the backbone of emerging technologies, blockchain is not only used in the field of virtual currency, but also in other fields such as finance, medical care, intellectual property certification, etc. a large number of excellent enterprises have emerged in China to explore or enter the blockchain instry. According to the in-depth analysis report on business model innovation and investment opportunities of blockchain instry released by foresight Instry Research Institute, as of the end of 2016, there were 105 blockchain related enterprises in China, 80% of which were concentrated in eastern coastal cities, including Shanghai, Hangzhou and Taipei
from the perspective of global blockchain technology application development, as of April 2017, financial service companies accounted for 55.43% of the 267 blockchain venture capital companies; From the perspective of the Chinese market, 34 of the top 50 blockchain venture capital companies in 2016 are involved in financial services, mainly in cross-border payment, bill discounting and financial service platform<
analysis of the development trend of blockchain
the combination of blockchain and cloud computing is more and more close, and baas is expected to become a public trust infrastructure
cloud computing is the general trend. We believe that the combination of blockchain and cloud is also an inevitable trend. There are two modes for the combination of blockchain and cloud, one is blockchain in the cloud, the other is blockchain in the cloud. The latter, namely baas, blockchain-as-a-service, refers to that the cloud service providers directly provide blockchain as a service to users. In the future, more and more cloud service enterprises will integrate blockchain technology into the ecological environment of cloud computing. By providing baas function, they can effectively rece the deployment cost of enterprise application blockchain and rece the initial threshold of innovation and entrepreneurship
the security problem of blockchain has become increasingly prominent, and security protection needs the overall consideration of technology and management
blockchain system is almost perfect mathematically, with the advantages of openness and transparency, difficult to tamper, reliable encryption, anti DDoS attack, etc. However, from the engineering point of view, its security is still restricted by infrastructure, system design, operation management, privacy protection and technology update iteration. In the future, we need to consider the overall situation of technology and management, strengthen basic research and overall protection, so as to ensure the application security
the competition of blockchain is becoming increasingly fierce, and patent competition has become an important field of competition
with the increase of participants, the competition of blockchain will become more and more fierce, and the competition is all-round, including technology, mode, patent and other dimensions. We believe that in the future, enterprises will strengthen the layout of blockchain patents. Since 2014, the number of blockchain patent applications has grown explosively. Blockchain patents are mainly distributed in the United States in North America, the United Kingdom in Europe, China and South Korea in Asia, and this pattern will be maintained in the future. The patent gap between China and the United States is narrowing, and the number of applications in China in 2016 has surpassed that in the United States. It can be predicted that the patent competition of blockchain will become increasingly fierce in the future
with the acceleration of domestic policy process, the development of the instry ushers in a new opportunity
blockchain has attracted attention from all walks of life e to its core advantages of high performance, high security, high-speed access, efficient operation and so on. In the context of the rapid development of blockchain, China conforms to the needs of globalization, closely follows the international pace, and actively promotes the research, standardization and instrialization development of domestic blockchain related fields
trustworthiness is the core requirement of blockchain, and the importance of standards and specifications is becoming increasingly prominent
in the future value delivery network based on blockchain, we will completely use algorithms and software to build the trust foundation. However, we believe that this is far from enough, and we need the standard to increase the credibility of the blockchain. In the future, the standard of blockchain will standardize the technology and governance of blockchain from the perspective of users, business oriented, and from the dimensions of smart contract, consensus mechanism, private key security, and authority management, so as to enhance the credibility of blockchain and add weight to the trust of blockchain.
(1) Technical level. Since 2007, distributed computing has affected technical developers, so it is normal for bitcoin to appear in the field of virtual currency
(2) hardware level. The popularity of PC servers and the exponential growth of computing power (3) commercial level. The three characteristics of blockchain, namely, decentralization, distrust and extremely difficult forgery, just meet the needs of recing the trust cost and speeding up the transaction speed in financial fields such as stock trading and bank settlement (4) political level. Blockchain can rece the transaction cost to a certain extent, but the anonymity and untraceability of blockchain cause huge political risk[blockchain as the underlying technology of bitcoin was proposed at the end of 2008]
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

what is distributed and decentralized? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer before they could finish the legal process. What if we use blockchain technology? As long as two people agree to get married, and then release a message in the circle of friends, the process of marriage is completed, and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses, they may be distributed all over the world, but their mobile phones will help you record the information and tell others who want to know
if you want to hide the marriage information, you used to just modify the records on the computer of the Civil Affairs Bureau, but now you have to modify the records on the mobile phones of all the people who know the truth at the same time. The more people who know the truth, the less likely they are to modify it, so it is an impossible task. This is distributed and decentralized
deepen the understanding
on the network, every once in a while, a block will be generated. This block is equivalent to a network logbook, which is used to record the relevant information that happened in a period of time. When the logbook is full, a new logbook will be generated. Once the information is recorded, all participants will be informed, and everyone's logbook will be updated synchronously
these logbooks are finally connected in series, which is blockchain technology. Because of the use of cryptography technology, if someone wants to tamper with the message unilaterally, through the verification of blockchain algorithm protection mechanism, if the time point is not right and the associated information is not right, other people will not update their own record book, and the information will be invalid
therefore, compared with the traditional information storage technology, blockchain technology is more secure, transparent and irreversible
concept differentiation
blockchain is not equal to bitcoin, it is just a kind of underlying technology invented to realize bitcoin as a digital currency. Blockchain can be applied to a wider range. In addition to digital currency, it can also be applied to P2P loan, global payment, micro finance, electronic payment, remittance and other financial aspects. It can also be applied to intellectual property, election, notarization and other aspects of people's livelihood.
