Blockchain economy through
blockchain is decentralized, tamper resistant and anonymous
the blockchain system is actually a distributed system
bitcoin system is the earliest blockchain system and the simplest blockchain system
the whole bitcoin system is actually a distributed ledger. This ledger is backed up on each node. When a transaction occurs, it will be broadcast to the network. The miner node (the node solving the problem) in the network will mine (the node solving the problem) to record the transaction. The recorded block will be broadcast to the network, and other nodes will verify and synchronize to their own node's account book.
Blockchain instry presents rapid development, helping the real economy to rece costs and improve efficiency
at present, a new round of scientific and technological revolution and instrial change sweeping the world, big data, cloud computing, Internet of things, artificial intelligence, blockchain and other new technologies continue to emerge, and the digital economy is profoundly changing the way of human proction and life, becoming a new driving force of economic growth. As a disruptive technology, blockchain is leading a new round of technological and instrial changes in the world, and is expected to become
the "source" of global technological innovation and mode innovation, and promote the change from "information internet" to "value Internet"
in China's 13th five year plan for national informatization, blockchain is regarded as a key cutting-edge technology, and it is clearly proposed to strengthen the innovation, experiment and application of new technologies such as blockchain,
in order to seize the leading power of the new generation of information technology. At present, China's blockchain technology continues to innovate, and the blockchain instry has initially taken shape. It has begun to be rapidly applied in supply chain finance, credit reference, proct traceability, right trading, digital identity, electronic evidence and other fields. It is expected to promote China's economic system to achieve technological change, organizational change and efficiency change, and make an important contribution to the construction of a modern economic system
as of June 2018, China's blockchain related business has initially formed a scale under the promotion of the government, enterprises and capital, and is in the forefront of the world in terms of the number of patents, financing environment, policy support and application landing
the instry is developing rapidly, and the number of enterprises is increasing rapidly.
according to the statistical data of in depth analysis report on business model innovation and investment opportunities of blockchain instry published by prospective instry research institute, there were 406 patent applications related to blockchain in the world in 2017, of which 225 were from China. As of the end of March 2018, the number of blockchain based companies in China has reached 456. The blockchain instry has initially formed a scale. From the upstream hardware manufacturing, platform services, security services to the downstream instrial technology application services, instry investment, media publicity, talent services and other instrial chain links are basically complete
from the change of the number of newly established companies in China's blockchain instry, the number of Companies in this field began to increase in 2014, and the number of newly established companies increased significantly in 2016, more than 100, more than three times of 2015. 2017 is the peak period of blockchain entrepreneurship in recent years. Due to the rapid popularization of blockchain concept and the graal maturity of technology, many entrepreneurs swarmed into this field, and the number of newly established companies reached 178
from equipment manufacturing to instrial application, the context of the blockchain instry chain is graally clear.
from the distribution of newly established companies in the blockchain instry segmentation field, as of the end of March 2018, the number of instrial application companies in the blockchain field is the largest, including 86 companies providing application services for the financial instry and 109 companies providing application services for the real economy. In addition, there are more than 40 related companies in blockchain solutions, underlying platforms, blockchain media and communities
from the perspective of the distribution of investment events in the blockchain instry segments, companies related to instrial application services have the largest number of investment events, with a total of 113. It can be seen that investors are paying more and more attention to projects with specific application scenarios that can be actually implemented. The number of events in the field of underlying platform is 42, and the number of events in the field of blockchain media and community is 28. The field of blockchain is attracting more and more entrepreneurs and capital, becoming a new highland for innovation and entrepreneurship. With the development of blockchain technology and the acceleration of application, the instrial scale will continue to increase, and this field is expected to become a new economic growth point in the future
the influx of Internet giants has rapidly promoted the development of China's blockchain instry
blockchain technology is not only favored by start-ups, but also widely concerned by internet giants. Internet giants have expanded their blockchain business and rapidly promoted the development of China's
blockchain instry. At present, Tencent, Alibaba, Internet, Jingdong and other Internet instry giants have joined in the research and scenario application of blockchain technology
the regional distribution is relatively concentrated, and the instrial agglomeration effect is obvious.
from the perspective of the regional distribution of China's blockchain companies, Beijing, Shanghai, Guangdong and Zhejiang are still the concentration places of blockchain entrepreneurship, accounting for more than 80% of the total. Among them, Beijing is in the absolute leading position with 175 companies, accounting for 38%; Shanghai ranked second with 95 companies, accounting for 21%; Guangdong Province ranked third with 71 companies, accounting for 16%; Zhejiang Province ranked fourth with 36 companies, accounting for 8%. In addition, Jiangsu, Sichuan, Fujian, Hubei, Chongqing and Guizhou are among the top ten provinces in China's blockchain entrepreneurial activity
the application of blockchain is diversified, extending from finance to the field of entity
blockchain technology has the characteristics of distributed, tamper proof, high transparency and traceability, which is very suitable for the business needs of the whole financial system. Therefore, it has been applied in payment and clearing, credit financing, financial transactions, securities, insurance, leasing and other sub fields. For example, Minsheng Bank and China CITIC Bank jointly launched the first domestic L / C blockchain application, and Ping An of China's two major application scenarios of asset trading and credit reference have been online. China Merchants Bank has landed the first domestic blockchain cross-border payment application, and Weizhong bank has shortened the reconciliation time from t + 1 day to t + 0 day through the inter agency reconciliation platform based on blockchain, realizing daily quasi real-time reconciliation
with the graal maturity of blockchain technology innovation and development, the actual effect of instrial application has become more and more obvious
now, the application of blockchain has extended from the financial field to the physical field, including electronic information deposit, right management and trading, proct traceability, digital asset trading, Internet of things, intelligent manufacturing, supply chain management and other fields. Blockchain technology began to be deeply integrated with the real economy instry, forming a number of "instrial blockchain" projects, ushering in the era of "a hundred flowers bloom" of instrial blockchain
to realize "informatization of cooperation links" and help the real economy rece costs and improve efficiency, Specifically, we can promote the development of traditional instries from two aspects of "cost rection" and "efficiency improvement"
in addition to low cost and high efficiency, blockchain can also realize "trust transfer" or "trust spillover". Based on blockchain technology, since the information on the chain can not be tampered with, after the two parties jointly verify a transaction, the third party can also trust the information, In fact, this kind of trusted state can be transmitted to a third party, and then realize the capitalization of data. In addition, it is very easy for institutions to turn from the "black box" state to the "white box" state, that is, the operational mechanism of institutions is transparent, which makes it very easy to prove their innocence and greatly reces the cost of mutual trust between multi-agent
Further, blockchain will play the role of "improving the efficiency of instrial chain coordination". To improve the level of instrial collaboration is an important way to promote made in China to move towards the middle and high end, and also an important requirement for building a modern economic system. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international tradetechnology abuse leads to certain risks in instrial development, which can not be ignored
although the positive value of blockchain technology graally appears, there are still a series of risks that can not be ignored in the process of instrial development. On the one hand, it is compliance risk. In the early stage of the development of blockchain, because it has the property of transmitting value, it has attracted some behaviors that are not focused on technology application, but are keen on illegal fund-raising, pyramid selling and even fraud through ICO (initial token issue)
the instrial policy system has been graally constructed, and the instrial development environment has been continuously optimized. In December 2016, the notice of the State Council on printing and distributing the 13th five year plan for national informatization first mentioned blockchain, and took it together with quantum communication, artificial intelligence, virtual reality, big data cognitive analysis, driverless vehicles and other technologies as key cutting-edge technologies, clearly proposed the need to strengthen the innovation, testing and application of blockchain and other new technologies, In order to seize the leading power of the new generation of information technology. Secondly, relevant instry, national and international standards are also speeding up to solve the key technical standards of blockchain and promote the ecological development of blockchain instry. In order to grasp the development opportunity of blockchain instry and seize the commanding point of blockchain instry development, local governments timely issued blockchain technology and instrial development support policies, which ushered in a new outbreak of blockchain instry
at present, local governments are actively positioning blockchain technology from the perspective of instry and seizing the new opportunities brought by technology upgrading. For example, in March 2018, the Hebei provincial government issued the guiding opinions on accelerating instrial transformation and upgrading and building a modern instrial system, proposing to actively cultivate and develop future instries such as blockchain and build a world-class high-tech instrial cluster
According to the overall plan of the 19th National Congress of the Communist Party of China, preventing and defusing major risks is one of the priorities of China's economic work in the next three years, and the key to preventing and defusing major risks is to prevent and control financial risks. Therefore, China also actively strengthens instry supervision, prevents possible financial risks in the process of blockchain development, maintains the stability and security of national finance, and promotes the healthy development of blockchain instry, so as to better play the positive role of blockchain "value Internet"blockchain is a cutting-edge technology, and the new regulatory challenges caused by technology also require the continuous progress of regulatory technology. "Reg tech" (regulatory Technology) in the financial technology segment. It is to use new technologies such as big data, artificial intelligence and blockchain to solve regulatory compliance problems and rece compliance costs. Blockchain filing platform and blockchain based regulatory system all belong to the field of reg tech. There have been companies engaged in regulatory technology in China, which mainly provide regulatory technology solutions for the government, major banks and other financial regulatory agencies. Jinqiu technology, zhongxiangbit and other companies have launched a supervision system based on blockchain
MBA think tank defines "digital assets": digital assets refer to non monetary assets owned or controlled by enterprises, existing in the form of electronic data, held in daily activities for sale or in the process of proction
in our life, direct consumption in Alipay is a common way to use digital assets, that is, the electronic payment system. Besides, we often use network office, Internet stocks, online reading or video broadcasting, which are using digital assets. For enterprises, online coupons or points are the use of digital assets, and some companies also distribute equity in the form of digital assets
2. Why digitalize assets<
as for the allocation of private digital assets, Xiao Feng, vice chairman of Wanxiang holdings and chairman of Tonglian data, said at a financial technology investment summit that in order to get more than expected returns, it means that we must adopt a different way of asset allocation from others. In the future, the most obvious opportunity for alternative asset allocation may be digital assets. In the next 10 years, This new asset class cannot be ignored. For the society, asset digitization is a major trend
the bat empire is soaring in the digital economy of the Internet. In recent years, Didi, meituan, P2P lending and ofo are all inseparable from two key factors: asset circulation and sharing economy. The most convenient way of asset circulation is undoubtedly to digitize assets! The essence of sharing economy is to make the real assets more convenient for resource sharing through intelligent digital way. Through technical means to rece the waste of resources and rece costs
for enterprises, asset digitization is the best solution to rece costs and increase efficiency. If the privacy file is encrypted and saved by technical means, the security will be far greater than that in the entity. And digital assets are also convenient for enterprises to manage. When the era of big asset management comes, asset management needs to face thousands of asset types, involving a large number of calculations, which can not be completed by manpower alone
③ why use blockchain technology to digitize assets
1. Distrust. Through the distributed system of the blockchain, the trust between people is transferred to the trust in the machine, and the machine will not cheat people - it has no feelings and only operates in its own way. This greatly reces the number of central links generated by trust. In some instries, intermediaries can even be removed. Supply and demand trust is entirely based on this magical machine
2. Decentralization. At present, if you want to transfer the equity you hold, you have to go through a lot of proceres and find different departments to do it well. It's a waste of time and money. If blockchain technology is combined with electronic contract, this problem can be solved. Shareholders can trade their shares just like buying and selling T + 0 shares, and they are also protected by law. What about cross chain technology Cross chain: for example, you directly use your shares to buy other people's digital rights, recing the steps of exchanging legal currency.) How convenient that would be
3. Highly transparent. Now the business's biggest fear is information opacity. The application of blockchain technology can solve this problem. As long as the public digital assets are set up, everyone can view them. If necessary, the number of assets held by the owner can even be displayed, and some shady transactions can be avoided
4. Anonymization. We often do "streaking" on the Internet carelessly. Our information is sold at a price in some bad companies. We check all the system records of a person for several hundred yuan. We can receive some sales calls from time to time in our daily life, and most of the fraud calls are successful only after we know your information. In the blockchain, we only display one address for transactions, which can effectively protect our own information and rece the possibility of information being sold publicly
blockchain technology is a "customized" technology for its security, confidentiality, openness and transparency in asset digitization.
secondly, blockchain will play a role of "improving the efficiency of instrial chain collaboration". Enhancing instrial collaboration is an important way to promote manufacturing in China to move towards the middle and high end. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international trade
thirdly, blockchain will play a role of "building an honest instrial environment". At present, the construction of China's social credit system is accelerating, but in some cases, the process of building trust among partners is still slow, it is difficult to obtain all kinds of credit information, and it is difficult for small, medium and micro enterprises to obtain credit loans from financial institutions. Through the "transaction on the chain", all aspects can more easily find out the accurate historical credit situation of the counterparties, and establish the cooperation mechanism faster; Banks can also give credit to enterprises more safely based on transaction records, and promote the solution of the problems of "difficult, expensive and slow financing" of small, medium and micro enterprises operating in good faith
in addition, blockchain can make use of smart contracts to avoid default and fraud to a large extent, and can also make efficient and convenient payment scenario applications in combination with blockchain asset wallet. As early as in the blockchain circle, there have been many innovation forums and Instry Summit aiming at the direction of blockchain enabling the real economy, and combining with the local economic instry to carry out landing optimization. For example, the world blockchain conference Macao station intends to make a deep integration with the local economic instry, and use and popularize the blockchain assets with the payment means of magic chain wallet.
the core of blockchain technology is that all participating nodes jointly maintain the transaction and database, which makes the transaction based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party< br />?
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the blocks of the transactions that have been reached are connected together to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash formed by the previous block, and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All miners compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction
1.1 what is a blockchain
blockchain is a technical solution to collectively maintain a reliable database through centralization and de trust in the past. This technical solution mainly allows any number of nodes in the participating system to generate a series of data blocks by using cryptographic methods. Each data block contains all the information exchange data of the system in a certain period of time, and generates a data fingerprint to verify the validity of its information and link to the next database block< br />?
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems, that is, a big ledger. So it's very important who keeps this account book. At present, whose system is responsible for bookkeeping, the account book of each bank is the account book of each bank, and the account book of each bank is the account book of Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there are new transaction data changes in a certain period of time, everyone in the system can make bookkeeping. The system will judge the fastest and best bookkeeper in this period, write the recorded content into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. As a result, the data becomes very secure. Tamperers need to modify more than half of the system node data at the same time to truly tamper with the data. The cost of such tampering is so high that it is almost impossible. For example, bitcoin has been running for more than seven years, and countless hackers around the world have tried to attack bitcoin, but so far there have been no trading errors. It can be considered that bitcoin blockchain has been proved to be a safe and reliable system< br />?
1.2 why is there blockchain innovation
human beings need to communicate in the process of activities, and communication is based on information. In the past, information circulation was not convenient enough to meet the information needs of market participants, so the intermediary and center were born. This centralized system has the problems of high cost, low efficiency, scattered value, "information island" and unsafe data storage. However, e to technical and environmental factors, this system still continues to operate for many years until the emergence of the Internet. The starting point of the first generation Internet is TCP / IP protocol, which is to implement the open code of peer-to-peer transmission of information in a unified format of all nodes on the network, and to program, protocol and execute the basic values of freedom and equality needed by the global unified market. Internet eliminates the middle chain of low value and high cost, and realizes the low cost and high efficiency of global information transmission by decentralization< br />?< However, the first generation Internet did not solve the credit problem of information. The activities that can be decentralized on the Internet must be those that do not need credit endorsement, and those that need credit guarantee must be those that are centralized and participated by third-party intermediaries. As a result, Internet technology, which is unable to establish global credit, has encountered great obstacles in its progress - people can not participate in any value exchange activities on the Internet in a decentralized way. In order to realize value exchange, people still need the third-party intermediary (such as bank, clearing, exchange) based on credit. There are still some problems in the global centralized credit system, such as high operating cost, low efficiency and vulnerability to attack. For example, the legal currencies of different countries have different credit values and different clearing systems, which increase the cost of Global trade< br />?
therefore, what the second generation Internet must break through is: how to decentralize the establishment of global credit? So that the value transfer is also low-cost and efficient. We need to create a kind of technology in the Internet, which can also engage in value exchange activities on the premise that people can't trust each other, so as to achieve real decentralization and go to the third-party intermediary, and realize the transformation from information internet to value Internet
1.3 application of blockchain
Bubi blockchain has been applied to equity, supply chain, points and other fields, and is carrying out experiments and application tests with exchanges and banks
as an integral application on Bubi blockchain, Shubei Hebao has been launched recently, which is a good demonstration for the landing application of blockchain technology in various instries
1.4 why the financial instry needs blockchain
trust is the foundation of the financial instry. In order to maintain trust, the development of the financial instry has spawned a large number of high-cost, low-efficiency, single point of failure intermediaries, including trusteeship, third-party payment, notaries, banks, exchanges and so on. Blockchain technology uses new encryption authentication technology and decentralized consensus mechanism to maintain a complete, distributed and tamperable account book, so that participants can ensure the security of funds and information through a unified account book system without mutual recognition and trust. This is of great significance to finance. Therefore, global financial giants are exploring blockchain applications one after another. On the one hand, this is to prevent the risk of being subverted; on the other hand, it is also "for our own use" to improve efficiency and rece costs, so as to consolidate, optimize and expand the existing power< br />?
first, blockchain can rece trust risk. Blockchain technology has the characteristics of open source and transparency. The participants of the system can know the operation rules of the system, verify the authenticity and integrity of the account book content and account book construction history, and ensure that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system and recing the trust risk of the system. For example, blockchain can avoid the current Internet Financial P2P running, fraud and other events< br />?
secondly, blockchain can improve the efficiency of payment, transaction and settlement. On the blockchain, the process of transaction confirmation is the process of clearing, settlement and auditing. Blockchain uses distributed accounting, all transactions are displayed in real time on a spreadsheet similar to global sharing, real-time clearing, and efficiency is greatly improved. For example, the U.S. securities settlement system is t + 3, but the blockchain can improve the efficiency to the minute level, which can rece the settlement risk by 99%, thus effectively recing the cost of capital and systemic risk< br />?
thirdly, blockchain can rece operating costs. Financial business systems and back office work are often faced with long processes and multiple links. Nowadays, no matter visa, master or all of them operate in a centralized way, money transfer has to go through a third party, which makes the cost of cross-border transaction, currency exchange rate, internal accounting and time cost too high, and brings risks to capital. Blockchain can simplify and automate the lengthy financial service process, rece the interaction between foreground and background, and save a lot of human and material resources, which is of great significance to optimize the financial business process and improve the financial competitiveness. The Bank of Spain believes that by 2022, blockchain technology will help the financial instry rece its bookkeeping costs by $20 billion< br />?
fourthly, blockchain can effectively prevent failures and attacks. The traditional financial model takes the exchange or bank as the center. Once the center fails or is attacked, the whole network may be paralyzed and the transaction will be suspended. The blockchain is supported by many distributed nodes and computer servers on the point-to-point network. The problems of any part will not affect the overall operation, and each node keeps a of the blockchain data. Therefore, the built-in business continuity of blockchain has high reliability and fault tolerance< br />?
fifthly, blockchain can improve the level of automation. Since all files or assets can be represented in the form of codes or ledgers, smart contracts and automatic transactions can be realized on the blockchain by setting the data processing program on the blockchain. For example, a smart contract can write a set of financial terms into the agreement to ensure the automatic execution and default payment of the contract< br />?
sixth, blockchain can meet regulatory and audit requirements. The records stored on the blockchain are transparent, traceable and unchangeable. Any record, once written to the blockchain, is permanent and cannot be tampered with. Any transaction between two parties can be tracked and inquired< br />?
in addition to the above positive effects on existing systems and business models, blockchain can also drive the birth of new business models. On the one hand, the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. On the other hand, blockchain greatly encourages the innovation and cooperation of the whole society through the opening and cooperation of source code. Of course, there will be a lot of problems and challenges in the application of blockchain in finance. This paper also thinks about the specific application
the working principle of blockchain technology is not difficult to understand. If we focus on the application research of specific blockchain technology, we can find that the working principle of this blockchain technology is ubiquitous.
