Promote blockchain technology and application breakthrough
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.
2) blockchain, Internet and artificial intelligence should be regarded as technologies of the same height, and blockchain should formally enter our hard science and technology development category
3) pointed out the development and application direction of our blockchain, including the speech that the technology of blockchain has extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital asset trading, and so on. In terms of application, there will inevitably be some regulatory or legal problems in the process of application, What are the instructions in this speech? He mentioned that we should implement the rule of law in the management of blockchain, and promote the safe and orderly development of blockchain
4) in the more important point of application and development, it is mentioned that the blockchain is from virtual to real, enabling entity, improving people's livelihood, obtaining instrial advantages, and better serving the development of the whole instrial economy. In fact, through the study of blockchain technology, from one side or the signal released, we express our attitude towards the innovation and leadership of blockchain. We hope that in the development of blockchain, we can first have our own core technology, and we should be a leader in today's fierce international competition
5) it is to enhance the market confidence of the whole blockchain instry, especially for the application and development of the whole blockchain technology. With a great increase in market confidence, it is bound to attract more people in the next period of time, including the capital market and for example, more talents and research applications will enter this field. More capital, more manpower and more other social related aspects, including the rule of law and legislation, will positively promote the application and landing of the whole blockchain technology. These are my four points of view or summary of blockchain technology learning
if you have been concerned about blockchain for a long time, in fact, from the national level, including the 13th five year plan, blockchain technology has been written into the 13th five year plan, which is developed as a parallel technology with artificial intelligence, big data and cloud computing. It has been introced in the second half of 2018, and the office of network information technology has put the blockchain application service on record, From all aspects, it is actually a positive guidance or protection for the development of the whole blockchain
of course, when it comes to blockchain, you may also say that blockchain always thinks of money speculation and so on. In fact, digital currency is only a relatively narrow field in the field of blockchain. We now include support from the mainstream of modern society or the national level, and more support for the application of blockchain technology in the real instry, The core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in the distributed system without mutual trust by means of data encryption, timestamp, distributed consensus and economic incentives, so as to solve the common high cost and low cost problems of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
- original title: market analysis of China's blockchain instry in 2019: enabling various instries to accelerate the application landing, there will be two opportunities for future applications
2019 - blockchain "mainstream application year"
since August 2018, the electronic invoice of blockchain was issued for the first time in Shenzhen. So far, it has issued more than 6 million electronic invoices, with an amount of 4 billion yuan, and has access to more than 5300 enterprises, Covering more than 110 detailed instries. In addition to the field of electronic invoice, blockchain has also been successfully implemented in many project scenarios, such as supply chain finance, legal deposit, cross-border payment, etc.
at the recent "thousands of people watching fire" conference of blockchain instry, the reporter of economic daily learned that in 2019, the technology implementation and application has brought blockchain into the "mainstream application year". On the one hand, many Internet giants have a solid technical foundation, on the other hand, they actively explore more valuable scenarios to find development opportunities in the enabling real economy
"blockchain technology can play the role of anchoring, sharing and increasing trust in the whole social information flow, making the chaotic information credible. Compared with the past, this is a" qualitative leap. " Zhang Kaixiang, chief architect of Weizhong bank's blockchain, said, "risk control and business rules design based on trusted data can improve efficiency, rece risks and rece operating costs." He pointed out that as a connector, it is not meaningful for a single enterprise to operate the blockchain, and it is more meaningful to share it as an open source solution to realize the ecological co construction of the instry
"we have been exploring and practicing open source, starting from the underlying technology platform and combining with the scenes of finance, instry, Internet of things, culture and entertainment, to jointly build an open, transparent and efficient technology and instrial community. Open source ecology helps to activate the creativity of the instry. We will continue to start from the open source community and improve a complete set of systems such as system construction and skills training, so as to benefit more people. "
in 2019, the market scale of China's blockchain instry will exceed 100 million yuan
China's blockchain instry is still in its infancy, but with the continuous support of national policies, the continuous progress of instry technology and the increasing demand of downstream application fields, China's blockchain instry is expected to continue to maintain high-speed growth. According to the statistical data of in depth analysis report on business model innovation and investment opportunities of China's blockchain instry published by foresight Instry Research Institute, the market scale of China's blockchain instry was less than 6 million yuan in 2011, and the market scale of China's blockchain instry increased by 32 million yuan by 2017, By 2018, the market scale of China's blockchain instry has reached 67 million yuan, always maintaining a rapid growth rate of more than 80%. It is predicted that the market scale of China's blockchain instry will exceed 100 million yuan in 2019, and that in 2022, driven by policy support and downstream demand, the market scale of China's blockchain instry is expected to exceed 450 million yuan
market size statistics and growth forecast of China's blockchain instry from 2015 to 2022 
data source: the audited enterprise asset confirmation, registration and circulation records, etc., sorted out by foresight Instry Research Institute, are stored on the platform in the form of traceability. Based on this, banks can carry out fast financing and loan business, save the cost of guarantee and other links, greatly improve the efficiency, and make the risk of financing and loan controllable as a whole
electronic data storage is an important application field of blockchain technology.
the provisions of the Supreme People's Court on Several Issues concerning the trial of cases by Internet courts, which came into effect in September 2018, clearly states that electronic data storage can be solved by blockchain and other technical means. Xiang Dan, vice president of bibox digital asset trading platform, said that electronic data deposit is an important application field of blockchain technology“ Blockchain technology has the characteristics of preventing tampering, leaving traces in the event, post audit and security protection, which is concive to improving the credibility and authenticity of electronic evidence. The combination of blockchain and electronic data storage can rece the cost of electronic data storage, improve judicial efficiency and enable judicial business. For example, the contract management based on blockchain has been applied in many Internet courts. "
according to Zhou Jianrui, co founder of coinword, a trusted content community, the application of electronic data storage based on blockchain can also help deepen the reform of "release management and service" and improve administrative efficiency. In Beijing Haidian District and other pilot areas, blockchain technology is playing the role of efficient data sharing, secure transmission and credit support. When applied in the field of government affairs, it can realize real-time data sharing of various departments and effectively assist window personnel and examination and approval personnel to quickly verify the authenticity of materials. For example, the public security, civil affairs, housing management and other departments "on the chain", in dealing with real estate transactions can be fast and accurate, "one key" verification of multi-party information, greatly saving social costs
there will be two opportunities for the application of blockchain
because the social recognition of blockchain is not high, the people who understand and use blockchain are still very limited, and the penetration of blockchain into the real economy still needs a graal process. " Yuan Yuming, CEO of fire coin China, introced that they used the open, transparent and tamper proof characteristics of blockchain to explore a new path of art traceability and anti-counterfeiting by means of high-precision full pixel scanning and archiving; By constructing the trust mechanism in the multi-party cooperation scenario, the integral information platform for multi-party participation and resource sharing is developed“ Next, there will be two opportunities for blockchain application:
one is training. With the entry of enterprise giants one after another and the continuous penetration of the real instry, more people will learn about blockchain through training, which will become a new market demand
the second is to provide consulting and technical solutions to more traditional enterprises to help them penetrate the blockchain into more traditional fields and promote the consumption rection, efficiency enhancement, transformation and upgrading of the real instry. "
The so-called blockchain technology, also known as the distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records
blockchain application:
1. Financial sector: mainly to rece transaction costs and Inter Organizational transaction risks. Blockchain applications in this field will mature as soon as possible, and banks and financial trading institutions will be the main promoters
financial blockchain
since the beginning of human society, financial transaction is an indispensable economic activity. The different roles and contents of transaction reflect different proction relations. Through the transaction, we can optimize the social efficiency and realize the maximization of value. The development of human society is inseparable from the evolution of transaction forms. It can be seen how important transaction is in human society. The essence of transaction is to exchange the ownership of value. Now, in order to complete the transaction (such as the ownership of houses and vehicles), some intermediate links are often needed, especially the role of intermediary guarantee. This is because there is often insufficient trust between the two sides of the transaction, it is not easy to confirm the ownership of value, and often the value of each other can not be directly exchanged. Reasonable intermediary guarantee ensures the normal operation of the transaction and improves the efficiency of economic activities. However, the existing third-party intermediary mechanism often has some shortcomings, such as high cost, long time cycle, complex process and error prone. Because of these, financial services have become one of the hottest application areas of blockchain. Blockchain technology can provide effective and reliable ownership proof and strong intermediary guarantee mechanism for financial services. Financial services include currency, securities, insurance, donation and so on
Credit reference and ownership management: This is the dream of large social platforms and insurance companies, but there is still a lack of sufficient data sources, reliable platform support and effective data analysis and management. The threshold of entrepreneurship in this field is very high, which needs top-down promotion. Because anything that needs to deal with the government has never been very good and will be carried out immediately
credit reference management is a huge potential market, which is said to exceed 100 billion scale (Ping An Securities report, Wells Fargo report), and it is also one of the most promising directions of big data application. At present, a large number of effective data related to credit investigation are mainly concentrated in the hands of a few institutions. Because these data are too sensitive, and are the lifeblood of business, they are often closely protected, thus forming a high threshold of the instry. Although a large number of Internet enterprises (the most successful one should be Facebook) have tried to obtain massive user information from various dimensions, there are still some problems in these data from the perspective of credit reference
• Insufficient data: the larger the amount of data, the higher the value can be obtained, and there is a lower limit for the effective value generated by data. The amount of data below the lower limit can not proce effective value
• Poor relevance: the most core data is often the most sensitive. In today's highly sensitive privacy era, users do not want to expose too much data to third parties, so there are few effective components in the data obtained by enterprises
• Lack of timeliness: the user data that enterprises can obtain from the public is often outdated, and even has false information, which seriously interferes with the credibility of relevant analysis
and blockchain has the characteristics of natural tampering and non repudiation. At the same time, blockchain may provide unprecedented scale highly relevant data, which can be accurately located in time and space and strictly associated with users. Therefore, providing data based on blockchain for credit management will greatly improve the accuracy of credit evaluation and rece the cost of evaluation. In addition, unlike the traditional manual audit, blockchain technology relies entirely on mathematical results, and the credit mechanism based on blockchain will naturally be stable and neutral. IDG, Tencent, Ernst & young, and PwC have all invested in or entered the field of credit information management based on blockchain, especially the application scenarios related to insurance and mutual aid economy
Resource sharing: companies represented by airbnb will welcome this kind of application, which will greatly rece the management cost. The threshold of entrepreneurship in this field is low, the theme is concentrated, and it will be popular with investmentin the era of big data, value comes from data mining. The more data dimensions, the larger the volume, the higher the potential value. For a long time, the headache is how to evaluate the value of data, how to use data for exchange and transaction, and how to avoid valuable data leaking out without permission. Blockchain technology provides the potential to solve these problems. By using the unified ledger composed of blockchain, the flow of data among multiple parties will be tracked and managed in real time, and the management cost of data sharing process can be effectively reced through the control of access rights
4. Investment management: both public and private funds can apply blockchain technology to rece management costs and control risks. Although there is a trial like Dao, we are cautious that the demand in this field is not mature. However, Xiaoyao has found that China's major start-ups have begun to test the water in this field, hoping for a major breakthrough
in international trade activities, buyers and sellers may not trust each other. Therefore, the two banks need to act as the guarantors of the buyer and the seller, to collect and deliver documents on behalf of the buyer, and to replace commercial credit with bank credit. Blockchain can provide a common account book for L / C transaction participants, allowing banks and other participants to have confirmed common transaction records and perform accordingly, thus recing risks and costs. With Dao (decentralized autonomous organization) as the representative of crowdfunding management, Dao has set the highest financing record in history, more than 160 million US dollars
5. Internet of things and supply chain: Internet of things is a very suitable field, and there will be a large number of applications in the short term, especially in specific scenarios such as leasing and logistics. However, the development limitations of the Internet of things will lead to the difficulty of large-scale application in the short term
the supply chain instry often involves many entities, including logistics, capital flow, information flow, etc. there are a lot of complex cooperation and communication between these entities. Under the traditional mode, different entities keep their own supply chain information, which is seriously lack of transparency, resulting in higher time cost and money cost, and it is difficult to trace and deal with problems (false claim, counterfeit goods, etc.). Through the blockchain, all parties can obtain a transparent and reliable unified information platform, which can view the status in real time, rece the logistics cost, and trace the whole process of proction and transportation of goods, so as to improve the efficiency of supply chain management. When disputes arise, the proof and tracing become clearer and easier. This field is considered as a promising application direction of blockchain. IBM has continuously invested in the research and development of the Internet of things for decades, and is currently exploring the use of blockchain technology to rece the cost of Internet of things applications
blockchain is applied only after it has technology, such as Huixin cloud platform: only when it has platform can proct managers enter the platform for development, so technology and application should progress together
the application of blockchain technology is different in the field of instry, and the functions and effects are also different. Let's take the field of credit system for example. Because the leakage of personal information will cause great harm to the informants, which makes them suffer from conservative harassment. What's more terrible is personal information leakage, which is usually accompanied by tens of thousands of personal information being stolen, illegally sold, and even using the formal data trading institutions to steal data
with the rise of blockchain technology, the encryption of blockchain technology can provide solutions for the protection of personal information. Blockchain technology can store personal information in a distributed way to avoid the security risks faced by a single server
and as one of the most ice breakers of blockchain technology research, jinwowo network technology has concted in-depth research and Application on blockchain technology. Jinwowo's big data service based on blockchain can eliminate illegal data reselling and reestablish data circulation rules from four aspects of data storage, data analysis, data tracking and data security
