Future application of blockchain
blockchain technology has realized the key characteristics of tamper proof, decentralization, anonymity, security and reliability. Now more and more instries choose to use blockchain technology. For example, NASDAQ has adopted blockchain technology to realize LINQ, a private equity trading platform. It is more secure, and the transactions stored in the blockchain can not be tampered with, that is to say, once written, it is impossible to be modified. In the future, the application of blockchain will be very wide, and all aspects can be applied to blockchain technology. For example, in the future, schools can store the electronic version of Graation Certificate in the blockchain, which will not be tampered with. Employers can check the authenticity of students' graation certificate by querying the information in the blockchain<

an overview of blockchain Technology: architecture, consensus, and future trends
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date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.
- 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. "
From District TV network Share: in 2018, blocklink bar AI has become the most popular technical term, and more and more technology companies have announced to enter the blockchain market. In the Internet, Xunlei, Renren, Fengfeng, Tianya and other companies have blockchain related actions. These companies share the same fate. They have all experienced prosperity, but after the impact of Internet entrepreneurship tide, they began to go downhill. Then they rubbed against the hot spots of blockchain and began to try to counter attack
Global blockchain instry investment is hot
according to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by prospective instry research institute, as of the end of April 2017, there were 455 blockchain companies in the world, with a total financing amount of US $1.947 billion. Among them, the total investment and financing of us blockchain related companies reached US $1.252 billion, accounting for 64.3% of the global market; The total financing amount of China's blockchain emerging enterprises is about US $114 million, accounting for 5.86%, ranking second in the world after the United States, and growing rapidly
at present, the overall survival status of blockchain is good, with a survival rate of 87.25%. Among all the invested companies, 47 have been closed, accounting for about 10.51%, and the other 10 have been acquired. Due to the change of competition pattern in bitcoin market, some companies have been forced to shut down. Meanwhile, some coin circle companies are graally transforming to chain circle companies.
exploration at the national level has also begun. On March 23, the information technology and Software Services Department of the Ministry of instry and information technology announced that it will study and explore the application of blockchain in the instrial field. Previously, the Ministry of instry and information technology said that it was preparing to establish a National Technical Committee for standardization of blockchain and distributed accounting technology to explore the formation of a complete blockchain standard system to better serve the development of blockchain technology instry
The application prospects of blockchain are mainly in the fields of finance, Internet of things and logistics, public services, digital rights and insurance
1. Blockchain has great potential applications in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can eliminate the third-party intermediary link and realize the point-to-point direct docking
2. Blockchain can also be naturally combined in the field of Internet of things and logistics, which is considered as a promising application direction of blockchain. The establishment of credit resources in the blockchain can double improve the security of transactions and improve the convenience of Internet of things transactions. It can save time and cost for the application of intelligent logistics mode
3. Blockchain is closely related to people's proction and life in public management, energy, transportation and other fields. The decentralized and fully distributed DNS service provided by blockchain can realize the query and resolution of domain name through the point-to-point data transmission service between nodes in the network
4. Through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection
5. In terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized
extended data:
the core technology of blockchain
1. Consensus mechanism, through the voting of special nodes, completes the verification and confirmation of transactions in a very short time; For a transaction, if several nodes with unrelated interests can reach a consensus, it can be considered that the whole network can also reach a consensus. The goal of blockchain consensus mechanism is to make all honest nodes keep consistent blockchain views
2. Asymmetric encryption requires two keys for encryption and decryption, which are public key and private key. The public key corresponds to the private key. The public key is used in the process of data encryption, and only the corresponding private key can be used to decrypt; On the contrary, the private key is used to encrypt the data, and only the corresponding public key can be used to decrypt the data
