Industry pain points of blockchain
what is centralization
the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent
the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers
the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high
at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know
so, in which fields can blockchain be applied, what kind of changes will it bring to our future life
the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud
core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people
Application:
1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment
2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute
3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city
4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords
in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.
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.
Original title: China's blockchain instry market status and development trend analysis in 2019, widely used to accelerate the construction of Digital China. Basically, a relatively mature instrial chain has been formed. With the promotion of national policies and the increasing demand of downstream application fields, the market scale of China's blockchain instry is constantly developing, the regional concentration is high, and the instrial cluster effect is obvious. With the increasing maturity of blockchain technology, the blockchain instry is entering the 3.0 stage as a whole. It has a good performance in finance, logistics, right protection and other fields, and has made great contributions to promoting China's digital construction and accelerating the process of Digital China
instrial chain analysis of blockchain instry: there are many downstream application fields with huge development potential
from the perspective of instrial chain, China's blockchain instry includes upstream hardware, technology and infrastructure; Midstream blockchain application and technical services
application fields of downstream blockchain. The upstream hardware, technology and infrastructure mainly provide the necessary hardware, technology and infrastructure support for blockchain application. The hardware equipment includes mining machinery, ore pool, chip manufacturer, etc; General technologies include distributed storage, decentralized transaction, data service, distributed computing and other related technologies
the downstream application fields include the combination of application blockchain technology and existing instries, mainly including financial instry, logistics instry, right protection, medical health, instrial energy and many other fields. As an emerging technology, blockchain has many downstream application fields and great development potential
the application and service of midstream blockchain includes the construction of infrastructure platform and the provision of technical service support. The construction of infrastructure platform is divided into general infrastructure chain and vertical domain infrastructure chain; Technical service support includes technical support and service support. Similar to upstream technology, technical support is responsible for providing buyers with a series of technical support based on blockchain procts, such as blockchain security protection; Service support includes a series of services such as digital asset trading place, digital asset storage, media community, etc
instry chain analysis of blockchain instry Most of 360 and other enterprises use their own financial companies to apply blockchain technology to launch a new mode of blockchain + finance and broaden the application scenarios of blockchain technology
With the continuous development of China's blockchain technology and the continuous expansion of blockchain application fields, China's blockchain instry will become the forefront of global technology development and open up a new international competition track in the future2. 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
4. Blockchain creates a new platform economy and opens a new era of sharing economy
5. Blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy
The blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidatedAnalysis on the expenditure scale and application prospect of China's blockchain instry in 2018 will be close to US $300 million in 2019, so as to solve the short board problem and promote economic development
blockchain technology is expected to be widely used in the economic field
blockchain technology has strong practical significance for cultivating new momentum of economic growth, building an honest society, improving the level of management technology and alleviating the financing difficulties of small and medium-sized enterprises, It is expected to be widely used in the economic field. At present, the application of blockchain technology is still in the early stage of development, facing many challenges. We should actively promote the application of blockchain in many economic and social fields, scenes and environments, create a good environment for instrial development, improve the quality of development, strengthen the research and development of blockchain core technology, professional application demonstration, and strengthen standard manufacturing Personnel training and the construction of public service platform
in 2019, the expenditure scale of China's blockchain market will be close to US $300 million
according to the statistical data of in depth analysis report on business model innovation and investment opportunities of China's blockchain instry published by prospective instry research institute , as of 2017, the expenditure scale of China's blockchain market is only US $83 million. In 2018, the expenditure scale of China's blockchain market will reach US $160 million. It is predicted that the expenditure scale of China's blockchain market will be close to US $300 million in 2019. At this stage, the overall market scale of blockchain is small, because most blockchain projects in the market are in the trial stage, with little investment. On the other hand, many enterprises have realized the potential of blockchain and plan to increase the budget in the future. Affected by this, China's blockchain market will usher in rapid growth. It is estimated that the market expenditure will reach US $1.95 billion by 2023, and the average annual compound growth rate will be 60.51% from 2019 to 2023
Statistics and forecast of China's blockchain market expenditure scale from 2017 to 2023. At present, blockchain technology is not mature in system stability, application security, business model, etc., which can not meet the requirements of "high efficiency and low energy", "decentralization" and "security" at the same time. First, performance. The transaction throughput that can be carried out on the blockchain is not high, and the current block capacity is very small, which leads to network congestion, and it is difficult to meet the needs of high-frequency business. Many projects are also starting to optimize, but there is still a certain distance from the transaction throughput of real scenes such as banks and stock exchanges. Second, consensus mechanism. In terms of energy consumption, consensus algorithms such as workload proof consume a lot of energy and cost, which makes blockchain waste a lot of network computing power and pairing power; In terms of types, there are too few types of blockchain consensus mechanisms at present. In the future diversified business scenarios, more abundant consensus mechanisms are necessary to adapt. Third, security. Privacy protection, harmful information on the chain, smart contract vulnerability, consensus mechanism and private key protection, computing power attack, cryptography algorithm security and other issues make the blockchain face a severe situation of platform security and application security. Fourth, the database problem. Different from traditional databases, blockchain applications require a lot of write operations, hash calculation and verification operations. The database system for blockchain is still a difficult point to break through2. Unclear application scenarios
currently, the blockchain project is still in the exploration stage, and no specific landing scenarios can be found. At present, the more promising fields are finance, sharing economy, Internet of things, public services, etc., but from the perspective of the existing blockchain technology maturity, there are still many problems in the application of blockchain, and there is still a gap from the actual use. First, the immaturity of blockchain technology restricts the implementation of commercial applications. At present, although there are many kinds of blockchain core technologies such as privacy protection algorithm and consensus mechanism, they generally do not have commercial availability. Second, the application mode of blockchain is still in exploration, and the "irreplaceable" advantage of blockchain has not been reflected. Blockchain itself represents a consensus system, so we should build a consensus system in line with the corresponding business scenarios from a higher level, rather than just "business + blockchain". There are many users in China, and the business scenario is complex. Moreover, any commercial proct will involve a very large flow and population. The current blockchain technology can not meet the demand
3, lack of professional talents
blockchain technology is a multi-disciplinary and interdisciplinary technology, which mainly involves operating system, network communication, cryptography, mathematics, finance, proction and so on. However, at present, there are still deficiencies in interdisciplinary and fields in China, and the supply of talents in related fields is seriously insufficient. On the one hand, there is a large gap of R & D technical talents. Blockchain technology research and development mainly focuses on go, JavaScript, C and C + programming languages, and new smart contracts use Haskell, Ocaml, rhoang and other new functional programming languages. In China's talent market, there is a big gap for technical talents with senior R & D experience in relevant languages. On the other hand, there is a lack of bottom design talents. Different from R & D technical talents, blockchain bottom system architecture designers need to master a number of interdisciplinary professional skills, not only to deeply understand the block chain bottom design principle, but also to have the system architecture design experience, but also to master the business logic of specific application scenarios. Although some colleges and universities have launched interdisciplinary ecation and blockchain special skills discipline setting, professional talents are still very scarce
analysis of favorable factors for the development of China's blockchain. In January 2017, the Ministry of instry and information technology issued the development plan of software and information technology service instry (2016-2020), which proposed that the innovation in blockchain and other fields should reach the international advanced level. In August 2017, the State Council issued the guidance on further expanding and upgrading information consumption and continuously releasing the potential of domestic demand, proposing to carry out the pilot application of new technologies such as blockchain and artificial intelligence. In October 2017, the State Council issued the guidance on actively promoting the innovation and application of supply chain, which proposed to study the use of blockchain, artificial intelligence and other emerging technologies to establish a credit evaluation mechanism based on supply chain
in March 2018, the Ministry of instry and information technology (MIIT) issued the key points for standardization of informatization and software service instry in 2018, proposing to promote the establishment of the national informatization and instrialization Integration Management Standardization Technical Committee, and the national blockchain and Distributed Accounting Technology Standardization Committee. In June 2018, the Ministry of instry and information technology issued the instrial Internet development action plan (2018-2020) to encourage the application and research of emerging cutting-edge technologies such as edge computing, deep learning and blockchain in the instrial Internet
since the blockchain was listed in the 13th five year plan for national informatization for the first time in 2016, the national government has paid more and more attention to the blockchain. 24 provinces and cities or regions, including Beijing, Shanghai, Guangdong, Hebei, Jiangsu, Shandong, Guizhou, Gansu and Hainan, have launched dividend policies to carry out the layout of the blockchain instry chain, Actively explore instry applications based on blockchain
At present, China's blockchain technology continues to innovate, and the blockchain instry graally takes shape, and has begun to be applied in supply chain finance, credit reference, proct traceability, right trading, digital identity, electronic evidence and other fields, which is expected to promote China's economic system to achieve technological change, organizational change and efficiency change, To make important contributions to the construction of a modern economic system. With the continuous influx of entrepreneurs and capital, the number of enterprises is increasing rapidly. The application of blockchain will accelerate the landing, boost the high-quality development of traditional instries, accelerate the instrial transformation and upgrading, use blockchain technology to "rece costs" and "improve efficiency" for the real economy, and boost the standardized development of traditional instries. In addition, blockchain technology is becoming a new business form and a new driving force for economic development. Blockchain technology is promoting a new round of business model reform and becoming an important support for building a social system of integrity In the past, the circulation of physical banknotes was difficult to trace, but with the application of blockchain technology, the flow of all digital assets will have a "chain" to check. For example, in the financial field, blockchain is expected to solve the pain points and difficulties in the payment field, rece the complexity of transactions, improve the end-to-end speed of transactions, rece the communication cost in the transaction process, and improve the transparency and non tamperability of transaction records. The cost of reconciliation, clearing and settlement among 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 among financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In addition, the application of blockchain will also extend to many fields, such as health care, ecation, charity, social management and so on. The market prospect is very broad
