What's the future of BNN blockchain

1. blockchain is a kind of technology. "In the simplest and most popular way, blockchain technology is everyone bookkeeping, or distributed ledger."
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.

2. Blockchain instry has great growth potential. Five aspects promote the healthy development of technology. Blockchain basic situation analysis blockchain technology, as a technical solution for collective maintenance of a reliable database in a decentralized way, has the characteristics of decentralization, tamper proof, highly scalable, etc., and is becoming a new technology following big data, cloud computing, artificial intelligence Virtual reality and other technologies are another emerging technology that will have a significant impact on the future, which is expected to promote human beings from the era of information internet to the era of value Internet. Some countries and regions in the United States, Japan and the European Union have promoted the development of blockchain as an important national development strategy, and vigorously promoted the research and development and application of blockchain technology. China also attaches great importance to the technological innovation and instrial development of blockchain. With the joint participation of it and other enterprises, a large number of new enterprises, new procts, new models and new applications have emerged. The application of blockchain in the fields of finance, government affairs, energy, medical and other instries has graally expanded, and is becoming an important force to drive the technological proct innovation and instrial transformation of various instries. The development of blockchain can be divided into three stages, namely, blockchain 1.0, represented by bitcoin and related financial infrastructure applications, and blockchain 2.0, represented by smart contract. At present, it is graally moving towards blockchain 3.0, which is based on blockchain technology and more complex in-depth application of smart contract. Statistical analysis of blockchain investment and financing in the first half of the year since 2016, the frequency and amount of investment and financing in China's blockchain field have increased sharply. According to the statistical data of "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, in the first half of 2018, the amount of financing in the blockchain field was about 10.7 billion, with a year-on-year growth rate of 1426% compared with the same period in 2017; The number of investment and financing events in the field of blockchain has reached 205, and it is expected that the investment in the field of blockchain will usher in another peak this year. Judging from the distribution of investment and financing rounds in China's blockchain field, the investment rounds in the start-up period (before round b) account for more than 95%. There are many instry pioneers participating in the investment together, and most enterprises are still in the race. Statistics and growth of blockchain investment and financing in the first half of 2014-2018 data source: prospective instry research institute collated the statistical analysis of Chinese blockchain enterprises and registered capital. In 2013 and before, there were only 26 blockchain related enterprises registered in China. In 2016, 116 blockchain enterprises were registered, 158 were registered in 2017, and 52 were registered from January to the end of June 2018. In terms of registered capital, there are 26 enterprises in China whose registered capital is less than 1 million yuan, accounting for about 6%; 197 companies have registered capital between 1 million yuan and 9.99 million yuan, accounting for about 46%; There are 171 companies with registered capital between 10 million yuan and 100 million yuan, accounting for about 40%; There are 31 companies with more than 100 million yuan, accounting for about 7%. Statistics on the enterprises and registered capital of China's blockchain enterprises from January to June 2013-2018 data source: prospective instry research institute collates the statistics of China's blockchain enterprises in terms of regions and fields. Among the 425 blockchain enterprises, 385 enterprises are gathered in Beijing, Shanghai, Guangdong, Zhejiang, Sichuan and Jiangsu, accounting for 90% of the total. Among them, Beijing has the largest number of enterprises, accounting for about 37% of the country. In terms of instry, China's blockchain enterprises are mainly distributed in the fields of finance, bottom public chain, enterprise services, technical solutions, data services, health care, Internet of things, transportation, games, etc. Among them, 91 enterprises are engaged in the financial field, accounting for more than 21%. China's blockchain enterprise field distribution statistics data source: prospective instry research institute collates that China attaches great importance to the development and application of blockchain technology. Driven by multiple forces such as policy, technology and market, the pace of blockchain innovation has been accelerating. It has been deeply integrated with cloud computing, big data, Internet of things and other technologies. The scope of exploration and application has also expanded from digital assets to supply chain management, intelligent manufacturing, instrial Internet, social welfare, right protection and other fields. Five aspects to promote the healthy development of blockchain technology, and promote the high-quality development of digital economy. 1. Pay close attention to the international development frontier, jointly promote the research of blockchain related technology and instry, promote the standardization of blockchain development instry behavior, and create a good development environment. 2. Strengthen the construction of blockchain core technology capabilities. Establish and improve the collaborative promotion mechanism among backbone enterprises, universities and research institutions, guide it enterprises to strengthen technical reserves, accelerate the breakthrough of key core technologies, and improve the performance, efficiency and security of blockchain. 3. Support the development of entrepreneurship and innovation in the field of blockchain, encourage the cross-border integration of blockchain enterprises and user units, guide instry organizations to establish public service platforms, support third-party organizations to carry out blockchain service evaluation and testing, promote the enrichment of instrial applications of blockchain, and serve the transformation and upgrading of entity economy. 4. Actively build and improve the blockchain standard system, accelerate the development and application of key standards, and graally build a perfect standard system. Actively connect with ITU, ISO and other international standards organizations, substantially participate in more international standardization work, and actively contribute more "Chinese power". 5. We will accelerate the improvement of the policy environment for blockchain development, support qualified enterprises to carry out application innovation and mode innovation, and guide and encourage enterprises, universities and scientific research institutes to jointly cultivate professionals needed for blockchain development. Support eligible blockchain enterprises to enjoy the preferential tax policies of the state to support the development of software instry and small and medium-sized enterprises. The instrial scale is small but the growth potential is huge. The blockchain economy is on the eve of the outbreak period. The financial instry is relatively widely used, and the application of other instries has also entered the stage of exploration and development. It is estimated that the direct market value of blockchain will increase from US $410 million to US $7.68 billion between 2017 and 2022

3. Since 2018, the blockchain instry has been booming. The exploration and application of blockchain is not limited to the underlying platform. Internet giants and financial giants have strengthened the application of blockchain in finance, public welfare, commodity traceability and other fields, especially in the financial field. The application with blockchain technology as the core has been accelerated
the blockchain instry is in the stage of rapid development
China's blockchain instry is in the stage of rapid development. According to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, by the end of March 2018, the number of blockchain companies with blockchain business as the main business in China has reached 456, from upstream hardware manufacturing, platform services, security services to downstream instrial technology application services, To ensure the development of the instry investment and financing, media, talent services, companies in various fields have been basically complete
according to the classification of application scenarios of top 20 enterprises in the ranking list, in addition to 13 enterprises focusing on the infrastructure and platform construction of blockchain such as underlying platform and blockchain hardware, the application scenarios of blockchain have graally enriched. According to the distribution of instry segments, there are 7 instry application companies, mainly Internet companies (Alibaba, Jingdong, Tencent) used in public welfare and commodity traceability, and innovative financial technology applications evolved by financial enterprises (Ping An, CMB, BOC), such as supply chain finance, bills and transaction clearing
as the blockchain can realize the non tampering of information, the possibility of data falsification is eliminated from the root, especially in the financial instry, which has high requirements for real data, it will embrace the blockchain more actively
analysis on the development trend of blockchain
Second, blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
3. Blockchain will be widely implemented in the real economy in the next three years and become an important support for the construction of Digital China
fourthly, blockchain creates a new platform economy and opens a new era of sharing economy
fifthly, blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy< Sixth, the blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidated
in addition, as an emerging technology, there are still many technical difficulties in the application of blockchain in the actual proction environment of the financial instry, such as throughput, scalability, consensus mechanism, privacy and security, manageability, etc
technological innovation such as blockchain is of great significance to the financial instry, which is expected to accelerate the process of "credible digitization" and continuously drive the financial instry to "move from virtual to real".

the research process of instry technology is constantly advancing

in recent years, the research process of global blockchain technology has accelerated, and the number of instry patent applications has increased rapidly. According to sopat statistics, from 2014 to 2018, the number of global blockchain patents continued to rise, and by 2018, the number of global blockchain patent applications had reached 2966. Among them, the number of patents in China's blockchain in 2018 accounted for 33.33% of the total number of patents in 2014, and increased to 82.1% in 2018

however, despite the continuous development and innovation of global blockchain technology in recent years, there is no universal evaluation standard and system to specify the technical performance, efficiency, scalability, security and other issues of blockchain. On the whole, blockchain technology needs further breakthrough

China's blockchain technology tends to serve applications

in terms of technology, the core of China's blockchain technology is to serve physical applications, while the US blockchain technology is still solving the potential problems of blockchain, which leads to the domestic focus on alliance chain applications, We hope to optimize the blockchain technology to meet the requirements of high concurrency applications; Foreign countries focus on the application of public chain, and carry out the optimization and innovation of core technology according to the characteristics of public chain. In terms of application, domestic blockchain focuses on the application of service instry and tends to be "non currency blockchain"; Most of the U.S. is a public chain, which tends to the circulation of digital assets

5. Blockchain is the biggest trend in the next decade
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

7. Thirty years ago, if someone asked you, where could the Internet change? No one knows. Today, although there are no really valuable killer and enterprise applications in the field of blockchain, it is undeniable that it provides us with a variety of possibilities in the future. Since blockchain has such a wonderful future, we can invest in advance now, and digital currency is the best way. The investment method is very simple. Register and open an account in the okex exchange, buy bitcoin, the mainstream currency, and hold it for a long time. I believe the days of soaring will not be far away.

8. You can go to Duoyuan to learn about it

9. The main difference between private blockchain and public blockchain is that jinwowo thinks that private blockchain only uses the general ledger technology of blockchain for bookkeeping, which can be a company or an indivial, enjoying the write permission of the blockchain. This chain is not very different from other distributed storage schemes.
