News communication of blockchain Technology
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.
blockchain is an important concept of bitcoin. It is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
the information websites in the instry now include:
1. Dig chain network: dig chain network is a professional blockchain media information portal. Dig chain network gathers the big data of global blockchain trading institutions, takes technology as the core, creates dig chain index, dig chain flash, dig chain College and other core sectors, excavates the value of blockchain, and serves as a platform for blockchain entrepreneurs, entrepreneurs and experts Blockchain investors provide one-stop blockchain service system
2. Golden Finance: a well-known old station in the instry
3. Color cloud bit: it is also the old cloud in the instry

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

On 19, 2018, "global media blockchain summit" was held in the financial hall of the Hong Kong stock exchange. The summit gathered more than 100 global media and dozens of top experts in the instry. At the meeting, we witnessed the establishment of the global media blockchain Alliance (bimg) and the release of bimg Hong Kong initiative, and discussed in depth the development prospect and instry trend of blockchain
member of the journalism and communication discipline evaluation group of the Academic Degrees Committee of the State Council Professor Yu Guoming, executive director of School of Journalism and communication of Beijing Normal University, delivered a keynote speech entitled "the value of mainstream media in the tide of technology" at the "2018 global media blockchain summit"
Yu Guoming said: "for the whole social communication in China and other major countries and regions in the world, including the process of blockchain construction, development In terms of the communication ecology in the process of evolution, the value of traditional mainstream media should also be indispensable. Although its share has really declined worryingly, such responsibility and value bearing are still very important. "
Yu Guoming further pointed out that traditional mainstream media's professional adherence, social status conferring function and local advantages are its great advantages. At the same time, with the development of social development and Internet technology, blockchain is not only a technology, but also a way to reorganize the society to a greater extent. Yu Guoming said: "in the words of Marx a hundred years ago, it is a technological form on top of such a new Internet technology as" Free Alliance of free people. ". To a large extent, it is a new form of social evolution after the Internet technology activates the indivial. Such a new form needs the mainstream media to play an important role in it, because in the process of such a new social evolution as blockchain, it is embodied in the so-called emergent evolution in system science, that is to say, the micro force and micro value released by Internet technology is a qualitative change in the development process and direction, which is a kind of social development A qualitative turning point in the development of the field, instry and market. "in the presence of all guests, the global media blockchain Alliance (bimg) was officially established at the meeting. Ding Laibin, Secretary General of the alliance, pointed out in his speech that the blockchain is really using the mechanism to let people see some changes that may occur in the future, and these changes may subvert the current state and make the social efficiency leap forward. In this process, the media function can not be absent, should play a supervisory role, exert a strong media supervision role, let investors distinguish right from wrong
Ding Laibin said: "the media is the public knowledge and conscience of the society and the supervisor of the development of the instry. To play this role well, we should be close to the game and stand where we can hear the gunfire. Therefore, if there is still a little distance between traditional media and blockchain before, let's eliminate this distance at today's summit. The listing of any enterprise is not the end, but the starting point. It is the same for many blockchain projects. From the beginning to the development, it also needs a lot of disclosure and planning, so that the enterprise can be presented to all the public and investors without reservation. It should be open and transparent, from the beginning to the end. Only in this way can the instry grow more healthily and more rapidly. "in the bimg Hong Kong initiative released at the event, Ding Laibin called on the media to join hands and make joint efforts to create a fair, just, honest, dynamic, harmonious and orderly instry public opinion environment; At the same time, the media should be encouraged to be open and inclusive, advanced in communication, and ecological innovation in information dissemination in the blockchain field, so as to continuously provide high-grade, high-quality information and services
