The third international blockchain

1. blockchain has developed in five stages
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.

2. The world blockchain conference, a semiannual world instry event in the field of blockchain, aims to build an international platform for global blockchain related instries to interconnect, share and co govern, and create a win-win situation.

3. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.

4.

China has started to establish a national standard for blockchain to promote the construction of blockchain standard system from top-level design, which is expected to be completed by the end of 2019 at the earliest

in this regard, Zhao Wu, founder of Beijing Huashun Xin'an Technology Co., Ltd., also said that although the blockchain has disruptive technology potential, we must realize that the blockchain is still in its infancy, far from reaching the stage of subverting the world

Yu Kequn stressed that the independent and controllable blockchain network is intended not to be controlled by others technically, but also to promote the healthy development of blockchain. Security is the future life of blockchain. Only its own security can make blockchain technology landing. This requires us to pay equal attention to the development of blockchain technology and its security attributes, even ahead of time

in this regard, Li Ming also said that an important part of the standard is the information security standard, which can also see the importance of security to blockchain technology. He also pointed out that the development of blockchain standards does not mean that it will rapidly promote the development of the instry, but give the instry certain guidance. Previously, China has suffered a lot in terms of international intellectual property rights and standards. In terms of blockchain, China has formed more than 200 patents in terms of international blockchain, and even stands in the forefront of world technology. Therefore, we also need to firmly grasp our right to speak

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

6. On the morning of June 22, 2016, the pre conference discussion of 2016 blockchain international summit was solemnly held in Beijing

7. What can blockchain do? Blockchain, a great technology with the birth of bitcoin, can greatly rece transaction costs and improve efficiency in the financial field, which is enough to make Wall Street excited. However, this is only the tip of the iceberg, and its potential application prospects are very wide, which will subvert all aspects of our lives in the future

blockchain is an important concept of bitcoin. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. One of the most basic characteristics of bitcoin is decentralization. In recent months, financial giants have graally begun to pay attention to the technology of bitcoin, and used it in non monetary fields, such as stock trading, election voting and so on 1) Art instry
artists can use blockchain technology to declare ownership, issue works that can be numbered and limited edition, and can target any type of art in digital form. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
(2) the real estate instry
uses blockchain technology to solve various problems faced by everyone when participating in real estate, including naming process, land registration, agency and so on
(3) the insurance instry
the financial instry has always been the most sensitive to advanced technology. Traditional banking and securities giants have been investing in blockchain venture capital since 2014, with a total global investment of US $1 billion in two years
(4) P2P wallet
personal assets can be traded through this P2P wallet in the future without going through any central organization, such as bitcoin

most blockchains are in their infancy, and most of them are overseas. There are very few good blockchain projects in China, so it is not recommended that any non professionals invest in blockchain projects. If you are very interested in blockchain technology and have technical or financial background, it is suggested to consider starting a business in this area. In terms of protocol system of blockchain, the bottom layer is the underlying technology of blockchain, including the technical protocol of blockchain, as well as some platform routing and basic algorithms; In the middle layer, we need to solve the problems of some application interfaces and the issuance and verification of some certificates, including the services of some instry platforms, big data analysis, etc. This is a rough division, and there should be more detailed division; The top is some applications of blockchain, including financial applications and other applications, Internet of things and so on

Introction to Bubi blockchain

since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely

the simple understanding of blockchain is a technology at the bottom of bitcoin, which is also a point-to-point e-cash system, which can realize point-to-point value express. We should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology. In the countries with more developed finance in the past, the technology of Finance and block has a long history, and the legislation of digital currency and block chain network is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own team and concept technology. Graally, regional banks are also participating in the discussion of digital currency. In addition to the application and support of this technology, blockchain has great influence on enterprises. For larger domestic enterprises, Bubi block is also applied to all kinds of equity In the fields of supply chain and points, domestic financial institutions and enterprises have focused on the value of new instries and developed their own blockchain platforms. Blockchain has instantly become a new domestic innovation instry. Overseas, compared with China, the United States has already obtained 15 blockchain patents at the end of last year. The application of blockchain finance is entering a new stage in an all-round way. Various applications will be more and more in-depth, and the relevant changes will attract more and more attention, which will also form a great new trend

financial institutions have launched blockchain technology into a new era of Internet and big data applications, which has laid a pattern from negative interest rate profit driven innovation to technological innovation. At this time, domestic giants have suggested that the cooperation alliance not only affects the implementation of financial infrastructure, but also is an important means to expand business cooperation. In terms of implementation, the future payment system securities deposit will not only affect the implementation of financial infrastructure, It is inseparable from the financial and settlement system and big data analysis, while the domestic giants join hands and propose a mutually beneficial cooperation mode, which can not only effectively improve operational efficiency, but also rece costs and find new growth points, After the adoption of blockchain technology, whether the company's procts and services can proce a new business model or a cost advantage far lower than that of competitors

what can blockchain do? What about blockchain? Although at present, there is no mature underlying blockchain technology platform solution, technical problems such as capacity scalability, privacy protection, non net settlement and non recourse need to be solved, and large-scale application of blockchain technology also needs to reset it architecture and reengineer business process, these are only technical problems. The real test of blockchain technology rooted and growing in the financial field is the regulatory agencies and financial institutions. Will the inherent "de supervision" and "de centralization" characteristics of blockchain make the market players have no power to drive technological innovation. However, because the blockchain is a technology based on mathematical algorithm, the establishment of trust relationship between all parties does not need the help of intermediaries or authority centers, and the cost of establishing trust relationship is almost zero (on the premise of the establishment of blockchain financial infrastructure and ancillary infrastructure), and the blockchain code is open-source, no geographical restrictions, and the network pattern is distributed and interconnected, It lays a technical foundation for the establishment and development of Inclusive Finance and shared finance in the future, and creates material conditions for the integration and unification of global finance. From this point of view alone, blockchain technology is bound to establish a core position in the future financial development, and rely on and complement each other with finance, and win-win in the future.

8. There are many blockchain content projects in China, such as coin, stemmit, etc. However, aqua is a relatively distinctive blockchain content project. The owner can download its DAPP to observe its difference from other projects. It is very creative in terms of publicity, objectives and functions. I hope it can help you.
