① How blockchain will open the door to trust

According to reports, there were 58 blockchain investment events in my country in the first quarter of this year, with a total investment of 681 million yuan. Blockchain: Whether it can open the door to trust has once again triggered heated discussions.

Data from third-party research institutions say that according to incomplete statistics, investment institutions invested a total of 1.271 billion yuan in the blockchain field last year and made 100 investments. In the first quarter of 2018, there were 58 blockchain investment events, with a total investment of 681 million yuan. Capital also regards blockchain as another "window" after the sharing economy and artificial intelligence.

② What signals does the blockchain 3.0 era give us

2017 is the first year of the blockchain explosion, and 2018 It will be the first year of blockchain implementation.

What kind of changes has the blockchain brought to the world from the 1.0 era to the 3.0 era?

The development of blockchain can be divided into three stages: peer-to-peer transactions, smart contracts and pan-blockchain application ecology (Token economy)

Blockchain 1.0 Era: Digital currency return rate is king

The 1.0 era now mostly refers to the digital currency era centered on Bitcoin. Digital currency transactions are the most important form for people to participate in the blockchain. At this stage, few people really pay attention to the application value of digital currency, let alone the practical value of the blockchain technology behind it. People focus on the rate of return of digital currency, which is equivalent to buying a stock on a different market, but this "stock" is relatively Active, the rate of return is astonishing, and of course it is also full of disasters.

Blockchain 2.0 era: smart contracts provide infrastructure support for upper-layer application development

The "smart contract" era is the real Programmable blockchain, usually represented by "Ethereum", supports Turing-complete scripting language at this stage, providing the necessary infrastructure for developers to develop any application on the "operating system" they set, realizing The actual application of virtual world has been implemented. The biggest contribution of Blockchain 2.0 is to completely subvert the concepts of traditional currency and payment through smart contracts. In the era of Blockchain 2.0, the blockchain has formed a trust foundation based on its traceability and non-tampering characteristics, providing a basis for smart contracts. A trustworthy execution environment makes it possible for contracts to be automated and intelligent. The biggest difference between smart contracts and traditional contracts is that they are not restricted by real social laws. For the contract subject to automatically execute the agreement after triggering the contract terms, the arbitration platform no longer determines the execution results in the smart contract but assumes responsibility. Responsibility for execution

Blockchain 3.0: The disruption to business lies in its transformation of production relations

We are now at the junction of the 2.0 era and the 3.0 era. The 3.0 era can be called It's people's attitude toward the futureIt is an idealized vision of the virtual digital currency economy. In Blockchain 3.0, people can truly realize assets on the chain, build a variety of applications within a large underlying framework, and create a trust-free, ultra-high-end A platform with strong transaction capabilities and extremely low risk can be used to realize the increasingly automated distribution of physical resources and human assets around the world, and promote large-scale collaboration in science, health, education and other fields.

Blockchain 2.0 builds infrastructure such as digital identity and smart contracts. On this basis, the complexity of the underlying technology is hidden, and application developers can focus more on application logic and business logic level. That is to say, we have entered the blockchain 3.0 era, and the symbol is the emergence of Token. Token is a value transmission carrier on the blockchain network, and can also be understood as a pass or token.

Token’s greatest impact on human society is its transformation of production relations. Joint-stock companies will be replaced, and every actual participant becomes the owner of productive capital. This new type of production relations encourages every participant to continuously contribute their own productivity, which is a great liberation of productivity. If this business activity is mapped to inflation in real society, as long as the former outperforms the latter, every Token holder will make a profit over time.

It is too early to talk about Blockchain 3.0. Although Blockchain has gone out of the conceptual stage, the current status of Blockchain technology development is that the underlying technology is still It is not mature enough and its applicable scenarios are relatively limited. On the one hand, there is still room for optimization and improvement in core blockchain technologies such as consensus algorithms; on the other hand, the processing efficiency of blockchain is still difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms all originated from abroad. Domestic blockchain technology service providers must patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. time period.

Competing among the heroes, the company that laughs last must be the company that really focuses on researching technology and developing practical applications! According to my observation, among the various applications based on Ethereum, the SEC social e-commerce chain has a very high chance of being implemented, and it is likely to become a killer application. There is a weekly report on the SECblock official account, which shows that the team is working hard.

③ What is the development trend of blockchain?

Since blockchain is going to become the future development trend, blockchain technology definitely has its own advantages over traditional technology.
1. Decentralization.
The core advantage of blockchain technology is that it does not require a traditional centralized institution. In a distributed system, it does not rely on point-to-point transactions, coordination and collaboration of a certain credit center, thus avoiding the ubiquitous data problems of centralized institutions. Issues such as safety, collaborative efficiency and risk control.
2. High safety.
In blockchain technology, data is difficult to tamper with. The database recording transactions can be accessed by anyone. In this transparent and open model, everyone can act as a supervisor. Everyone can see any changes in the data at a glance, which is more secure than traditional technology.
3. More reliable.
Blockchain technology connects multiple nodes in different places. The nodes in the blockchain interact through point-to-point communication protocols. Different nodes can be used by different developers using different programming languages ​​while ensuring consistent communication protocols. , different versions of full nodes to process transactions.
To put it simply, when a node encounters network problems, hardware failures, software errors, or is controlled by hackers, it will not affect the operation of other participating nodes and the system.
So compared to traditional technology, blockchain is more reliable.
So I firmly believe that the application of blockchain must be the future development trend.

④ What should the phenomenon and application of blockchain look like

1. The revolution of blockchain

Until the 7th year after the emergence of Bitcoin , its underlying core technology blockchain has only begun to become known to people. With the wealth effect caused by Bitcoin’s multi-million-fold increase, blockchain is becoming more and more popular. Its value is widely recognized and it is generally considered to be the core technology leading the fourth industrial revolution.

In 2018, Xu Xiaoping, a well-known angel investor, raised his arms and shouted: "The blockchain revolution has arrived! We must embrace this revolution!" With one stone, it caused thousands of waves, and soon the official blockchain learning book was launched online , official media interpreted that a wave of entrepreneurship and recruitment are coming one after another. In 2019, blockchain was officially designated as “an important breakthrough for independent innovation in core technologies.”

Under this situation, blockchain has become an out-and-out "new trend", and blockchain application has become a keyword. It has significant advantages in optimizing business processes and building trustworthy systems. How can we use these advantages of blockchain technology to empower the real economy?

Not only blockchain project parties are trying, but also Chinese Internet giants represented by BAT, financial systems and mobile operators represented by China Merchants Bank, Bank of China, and Ping An Insurance, etc. They are all actively carrying out "blockchain+", and it is also in full swing overseas. Facebook, Goldman Sachs, JPMorgan Chase, etc. are all actively promoting it.

2. Blockchain+

On August 10, 2018, Tencent issued the first blockchain electronic invoice. As of July 3, 2020, invoices were issued Volume reaches 25 million. Blockchain electronic invoices have the advantages of simple invoicing, on-demand supply, low cost, high efficiency, and anti-counterfeiting. Tencent Blockchain quickly occupied the market with first-mover advantages in blockchain + government affairs and blockchain + taxation.

Ant Financial, owned by Alibaba, began to deploy blockchain as early as 2015. So far, Ant Blockchain has an open alliance chain, BaaS platform and other products cover dozens of application scenarios. It has reached on-chain cooperation with many well-known global companies such as Intel, Jingdezhen Porcelain, and Bayer. The Internet also entered the blockchain very early and launched blockchain games, blockchain certificate storage and other services. Currently, the number of certificates stored on the chain has exceeded 100 million.

In 2019, the scale of China's blockchain industry alone reached 1.2 billion yuan. Data from the research institution Research and Markets shows that the output value of blockchain technology in the telecommunications field will surge from 4.66 million US dollars in 2018 to 2023. 993.8 billion US dollars in the year. Against this background, 2020 will usher in multiple policy benefits.

1. Officials have included blockchain into the scope of new infrastructure and new technology infrastructure;

2. Hunan released the "Three-Year Action Plan for the Development of the Blockchain Industry in Hunan Province" ( 2020-2022)";

3. Guangzhou launched the "Implementation Opinions of Guangzhou on Promoting the Innovation and Development of the Blockchain Industry (2020-2022)";

4. Beijing issued the "Beijing Blockchain Innovation and Development Action Plan (2020-2022)";

5. Jiangxi launched a blockchain service hall online;

6. Wuhan A special event for the transformation of blockchain technology scientific and technological achievements will be held;

7. The Chongqing Smart Expo Blockchain Application Innovation Competition plans to invest a huge amount of 50 million yuan as investment incentives.

However, although the implementation of blockchain in financial, government affairs, public welfare, games, agriculture, manufacturing, medical care, copyright and other physical fields has achieved remarkable results, it has also played an active role in fighting the new crown epidemic. role.

However, due to the influence of the general environment, more funds, resources, and attention have been attracted to the direction of blockchain empowering the real economy, but the core native applications of blockchain have been ignored.

3. Blockchain native applications

The Internet has opened an era of information explosion, and blockchain will bring a future where value flows freely. In today's global economic and financial system, affected by many factors such as ideology, cultural systems, business models, and technological levels, the cost of value transfer is high and the efficiency is low, especially in cross-border payment scenarios.

In the future blockchain era, value transfer will be like information transfer: global, instant, free, and equally enjoyed by everyone. All offline assets such as stocks, securities, identities, and real estate can be freely converted on the chain.

Moreover, the impact of blockchain technology has far exceeded the technical category itself. It is also an idea. The soul of blockchain lies in consensus. In the era of blockchain, truly powerful vitality will be bornBorn out of community consensus and application implementation, community and consensus will become the main body and soul of the industry.

In a community with consensus, individual energy and value will be fully stimulated, offsetting the fission effect of traditional centralization, breaking the original solid underlying structure, and reshaping new business and social values.

Therefore, blockchain native applications should be based on community and consensus, give individuals a path to realize their value, and be able to maximize the application ecosystem that stimulates individual energy and creativity, ultimately breaking monopoly and forming Decentralized free value exchange network.

Individual energy and value are multi-dimensional and highly subjective. These blockchain model designs obviously cannot fully stimulate individual energy, and are even far from it.

Native applications that truly conform to the spirit of blockchain should be grand and comprehensive in application model design, taking into account all online and offline value-creating behaviors of individuals for personalized use by individuals. , each individual’s areas of expertise are different.

Borrowing from the Pareto optimal solution theory, each individual's energy can be maximized to maximize the energy of the whole, and only then can the original centralized business model be broken and a free flow of global individuals be formed. A peer-to-peer value transmission network builds a new decentralized business infrastructure, changes the value creation and delivery model, and reshapes the values ​​of the entire society.

⑤ Blockchain technology development status and prospects

Block Current status and prospects of blockchain technology development
Blockchain technology originated from the foundational paper "Bitcoin: A Peer-to-Peer" published in 2008 on the cryptography email group by a scholar with the pseudonym "Satoshi Nakamoto" Electronic Cash System". In the past two years, the research and application of blockchain technology have shown explosive growth. It is considered to be the fifth disruptive innovation in the computing paradigm after mainframes, personal computers, the Internet, and mobile/social networks. It is also the evolution of human credit. The fourth milestone in history after blood relatives credit, precious metal credit, and central bank banknote credit. Blockchain technology is the prototype of the next generation of cloud computing. It is expected to completely reshape the form of human social activities like the Internet and realize the transformation from the current information Internet to the value Internet. Technical characteristics of blockchain

Blockchain has the characteristics of decentralization, time series data, collective maintenance, programmability, security and trustworthiness. Decentralization: The processes of verification, accounting, storage, maintenance and transmission of blockchain data are all based on the distributed system structure. Pure mathematical methods are used instead of central institutions to establish trust relationships between distributed nodes, thus forming a decentralized system. Centralized and trustworthy distributed system; time series data: the blockchain uses a chained area with timestampsThe block structure stores data, thereby adding a time dimension to the data and having strong verifiability and traceability; Collective maintenance: The blockchain system uses a specific economic incentive mechanism to ensure that all nodes in the distributed system can participate in the data The verification process of the block (such as the "mining" process of Bitcoin), and selecting specific nodes to add new blocks to the blockchain through the consensus algorithm; Programmable: Blockchain technology can provide a flexible script code system, Support users to create advanced smart contracts, currencies or other decentralized applications; Safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, and is formed with the help of consensus algorithms such as workload proof of each node of the distributed system. It uses powerful computing power to resist external attacks and ensure that blockchain data cannot be tampered with or forged, so it has high security. Blockchain and Bitcoin Bitcoin is by far the most successful blockchain application scenario. Blockchain technology has solved the double payment problem and Byzantine Generals problem that the Bitcoin system has long faced in the field of digital cryptocurrency. Different from the credit endorsement mechanism of traditional central institutions (such as central banks), the Bitcoin blockchain forms software-defined credit, which marks a fundamental change from centralized national credit to decentralized algorithmic credit. In recent years, Bitcoin has relied on its first-mover advantage to form a complete ecosystem and industry chain covering issuance, circulation and financial derivatives markets. This is also the main reason why it has occupied the vast majority of the digital cryptocurrency market share for a long time. The development context and trends of blockchain
Blockchain technology is a universal underlying technology framework that can bring profound changes to various fields such as finance, economy, technology and even politics. According to the current development trend of blockchain technology, blockchain technology will experience the blockchain 1.0 model with programmable digital encryption currency system as the main feature, the blockchain 2.0 model with programmable financial system as the main feature, and the blockchain 2.0 model with programmable financial system as the main feature. The blockchain 3.0 model is characterized by a programmable society. However, the above-mentioned models are actually developing in parallel rather than in an evolutionary manner. The digital cryptocurrency system of the blockchain 1.0 model is still far from mature, and is actually farther and more difficult from its vision of global currency integration. At present, the blockchain field has shown an obvious development trend driven by technological and industrial innovation, and relevant academic research is seriously lagging behind and urgently needs to be followed up. Basic models and key technologies of blockchain
Generally speaking, a blockchain system consists of a data layer, a network layer, a consensus layer, an incentive layer, a contract layer and an application layer. Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamp technologies; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates various consensuses of network nodes Algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contractsContract is the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology. Application Scenarios of Blockchain Technology
Blockchain technology can not only be successfully used in the field of digital cryptocurrency, but also has a wide range of application scenarios in economic, financial and social systems. According to the current status of blockchain technology applications, this article broadly summarizes the current main applications of blockchain into six scenarios: digital currency, data storage, data authentication, financial transactions, asset management and election voting: Digital currency: Bitcoin It represents a digital currency that is essentially generated by a distributed network system, and its issuance process does not rely on a specific centralized institution. Data storage: The characteristics of blockchain such as high redundant storage, decentralization, high security and privacy protection make it particularly suitable for storing and protecting important private data to avoid attacks caused by centralized institutions or improper permission management. Massive data loss or breach. Data authentication: Blockchain data is time-stamped, jointly verified and recorded by consensus nodes, and cannot be tampered with or forged. These characteristics make the blockchain widely used in various data notarization and audit scenarios. For example, blockchain can permanently and securely store various licenses, registration forms, licenses, certificates, certifications and records issued by government agencies. Financial transactions: Blockchain technology has a very high degree of compatibility with financial market applications. Blockchain can spontaneously generate credit in a decentralized system and can establish a financial market without the credit endorsement of a central institution, thereby realizing "financial disintermediation" to a large extent; at the same time, it can use blockchain to automate smart contracts and trustworthy transactions. The characteristics of programming can greatly reduce costs and improve efficiency. Asset management: Blockchain can realize the confirmation, authorization and real-time monitoring of tangible and intangible assets. Intangible asset management has been widely used in intellectual property protection, domain name management, points management and other fields; tangible asset management can be combined with Internet of Things technology to form "digital smart assets" to achieve distributed authorization and control based on blockchain. Election voting: Blockchain can implement applications such as political elections and corporate shareholder voting in a low-cost and efficient manner. At the same time, voting can be widely used in fields such as gambling, prediction markets, and social manufacturing. Existing issues with blockchain technology
Security threats are the most important issues faced by blockchain so far. Among them, blockchains based on the PoW consensus process mainly face the 51% attack problem, that is, nodes have the ability to successfully tamper and forge blockchain data by controlling more than 51% of the computing power of the entire network. Other issues include the potential threats of emerging computing technologies to crack asymmetric encryption mechanisms and privacy protection issues. The efficiency of blockchain is also an important factor restricting its application. Blockchain requires each node in the system to save a data backup, which is extremely difficult to store the growing mass of data. Although lightweight nodes can be deployedThis problem is partially solved, but industrial-grade solutions suitable for larger scales still need to be developed. The Bitcoin blockchain can currently only process 7 transactions per second, and transaction confirmation time is generally 10 minutes, which greatly limits the application of blockchain in high-frequency trading scenarios in most financial systems. The PoW consensus process highly relies on the computing power contributed by the blockchain network nodes. These computing powers are mainly used to solve SHA256 hashes and random number searches. In addition, they do not produce any actual social value. Therefore, these computing powers are generally considered Resources are "wasted", and a large amount of power resources are also wasted. How to effectively pool the network computing power of distributed nodes to solve practical problems is an important issue that blockchain technology needs to solve. As a decentralized distributed system, the blockchain network will inevitably have game relationships of competition and cooperation between its nodes during the interaction process, such as the block interception attack game of the Bitcoin mining pool. The blockchain consensus process is essentially a crowdsourcing process. How to design an incentive-compatible consensus mechanism so that self-interested nodes in a decentralized system can spontaneously implement the verification and accounting of block data, and improve the efficiency of non-profit organizations within the system. The cost of rational behavior to suppress security attacks and threats is an important scientific issue to be solved in blockchain. Smart Contracts and Blockchain Technology
Smart contracts are a set of scenario-responsive programmed rules and logic. They are decentralized, trustworthy and shared program codes deployed on the blockchain. Usually, after the smart contract is signed by all parties, it is attached to the blockchain data (such as a Bitcoin transaction) in the form of program code, and is recorded in a specific block of the blockchain after being propagated through the P2P network and verified by nodes. . Smart contracts encapsulate a number of predefined states and transition rules, scenarios that trigger contract execution (such as reaching a specific time or occurrence of a specific event, etc.), response actions under specific scenarios, etc. The blockchain can monitor the status of smart contracts in real time, and activate and execute the contract by checking external data sources and confirming that specific trigger conditions are met. Smart contracts are of great significance to blockchain technology. On the one hand, smart contracts are the activators of the blockchain, giving flexible and programmable mechanisms and algorithms to the static underlying blockchain data, and laying the foundation for building programmable financial systems and social systems in the blockchain 2.0 and 3.0 eras. On the other hand, the automation and programmable characteristics of smart contracts enable it to encapsulate the complex behavior of each node in the distributed blockchain system and become a software agent robot in the virtual world composed of blockchain, which helps Promote the application of blockchain technology in various distributed artificial intelligence systems, allowing the construction of various decentralized applications (Decentralized applications, Dapp), decentralized autonomous organizations (Decentralized Autonomous Organization, DAO), and Decentralized Autonomous Corporation (DAC) or even a decentralized autonomous society (Decentralized Autonomous Society (DAS)) becomes possible. The main development trend of blockchain and smart contract technology is from automation to intelligence. The essential logic of various existing smart contracts and their applications is mostly based on "IF-THEN" type conditional response rules based on predefined scenarios, which can meet the current needs of automated transactions and data processing. Future smart contracts should have "WHAT-IF" deductions based on unknown scenarios, computational experiments, and a certain degree of autonomous decision-making functions, thereby achieving a leap from current "automated" contracts to true "smart" contracts. Blockchain-driven parallel society
In recent years, a parallel society based on CPSS (Cyber-Physical-SocialSystems) has emerged. Its core and essential feature is virtual-real interaction and parallel evolution. Blockchain is one of the infrastructures for realizing CPSS parallel society. Its main contribution is to provide a set of effective decentralized data structures, interaction mechanisms and computing models for distributed social systems and distributed artificial intelligence research. And it has laid a solid data foundation and credit foundation for the realization of a parallel society. As far as the basis of data is concerned, management scientist Edward Deming once said: Everyone except God must speak with data. However, in a centralized social system, data is usually in the hands of a "few people" such as governments and large enterprises. It "speaks" for a few people, and its fairness, authority and even security may not be guaranteed. Blockchain data is stored in highly redundant distributed nodes and is in the hands of "everyone", enabling true "data democracy". In terms of the basis of credit, centralized social systems will inevitably have the characteristics of "Mertonian systems" due to their high engineering complexity and social complexity, that is, uncertainty, diversity and complexity, which are the center of social systems. Institutions and rule makers may behave dishonestly due to individual interests; blockchain technology helps realize a software-defined social system. Its basic idea is to eliminate centralized institutions and convert unpredictable behaviors into programmed codes of smart contracts. The form is deployed and solidified in the blockchain data in advance, and cannot be forged or tampered with afterwards and is executed automatically. This can, to a certain extent, transform the "Merton" social system into a "Newton" that can be fully observed, actively controlled, and accurately predicted. "Social system. The ACP (Artificial Societies, Computational Experiments and Parallel Execution) method is the only systematic and complete research framework in the field of parallel society management so far. It is the logical extension and logical extension of complexity science in the parallel social environment in the new era. Innovation. The ACP method canNaturally combined with blockchain technology to achieve blockchain-driven parallel social management. First of all, mechanisms such as blockchain's P2P networking, distributed consensus collaboration, and contribution-based economic incentives are themselves natural modeling of distributed social systems, in which each node will act as an independent and autonomous agent in the distributed system. Agent. With the improvement of the blockchain ecosystem, the consensus nodes of the blockchain and increasingly complex and autonomous smart contracts will form DAC and DAO in specific organizational forms by participating in various forms of Dapp, and ultimately form DAS, which is the ACP. artificial society. Secondly, the programmable nature of smart contracts allows the blockchain to carry out various "WHAT-IF" types of virtual experimental design, scenario deduction and result evaluation. Through this computational experiment process, optimal decisions are obtained and executed automatically or semi-automatically. Finally, the smart assets formed by the combination of blockchain and the Internet of Things make it possible to connect the real physical world and virtual cyberspace, and can achieve collaborative optimization of social management and decision-making through virtual-real interaction and parallel tuning of real and artificial social systems. It is not difficult to predict that in the future, when all physical assets in the real physical world are registered as smart assets on the chain, the blockchain-driven parallel society will arrive.

⑥ Are there any development prospects for blockchain community operations?

The prospects for blockchain community operations are very good. Mainly reflected in the following points.

First, the popularity of blockchain has not diminished in 2018. It can be as big as BAT or as small as a technology company. They all jumped into the blockchain.

Second, all blockchain projects require communities and communities to operate and fission users. According to reports, there is currently a shortage of more than 6,000 community operations personnel in large company blockchain projects.

Third, what is the future of blockchain projects? Some companies serving the blockchain will have very good development prospects.

So there are very good prospects for blockchain operations.

⑦ Blockchain Industry Public Opinion Research Report

Blockchain technology is considered to be the fifth core technology most likely to trigger a disruptive revolution. After experiencing a period of chaos And after the bubble period, with the intervention of national policies and the implementation of relevant supervision, +B39 will gradually get on the right track and develop in a healthy direction. In 2017, blockchain suddenly became popular all over the world and became the focus. If the emergence of blockchain made people in the industry excited at first, and ordinary people had an attitude that it had nothing to do with them and just passed by, then it can be said that blockchain has quickly and deeply entered the public's consciousness. view. The concept of blockchain was proposed by Satoshi Nakamoto in 2008. Its characteristics such as decentralization, non-tamperability, and traceability have attracted many investors to invest in it. Blockchain has gradually entered various industry fields, bringing not only considerable changes, but also some adverse effects. Analysts analyze and discuss the development trends of China's blockchain industry by collecting and organizing relevant data on China's blockchain industry.The rising trend of blockchain popularity is obvious. It can be clearly seen from the network index trend chart of blockchain and digital currency in the past six months that the popularity of blockchain has only increased. By the end of 2017, there was even an explosive rise. According to the trend chart, it can be predicted that the exponential growth of the blockchain network will show a gentle trend in the near future. The digital currency network index, which is closely related to the blockchain, was not much different from the network index of the blockchain before 2018. That was because the popularity of the blockchain detonated the value of Bitcoin, and many people took the opportunity to follow suit, causing the market to be chaotic for a time. . Since the beginning of 2018, the network index of blockchain has far exceeded that of digital currency. Such changes indicate that more people are focusing on blockchain, which will also be more conducive to the healthy development of blockchain technology. The value of digital currencies represented by Bitcoin has doubled, and ICOs have followed the trend. Financing models such as ICO are both similar to and different from traditional IPO financing methods. It can open up markets on a global scale and gain more development opportunities. However, due to the ulterior motives of many people and the fact that ICOs currently do not undergo any strict review process, chaos occurs frequently in the ICO market. The positive and negative impacts brought by ICO also make countries have different attitudes when facing this mixed market. According to the information table on the attitudes of some countries towards ICO, it can be seen that the most clear-cut attitudes are China and Japan. China completely bans ICO projects and defines them as illegal financing activities; Japan allows ICO projects and takes the lead in establishing a blockchain alliance; Countries such as the Philippines, Russia, and Canada adopt a regulation + development model, do not prohibit ICO projects, and actively build regulatory systems. Since the United States is a federal country, states have different attitudes. It is worth mentioning that the attitudes towards ICOs in Hong Kong and Macau are the same as those in mainland China, while Taiwan is very different. The person in charge of the "Taiwan Financial Regulatory Agency" promised to adopt a more friendly attitude to support enterprises. Development and adoption of cryptocurrency and blockchain technology in Taiwan. The top 10 national blockchain platforms are mainly concentrated in Beijing, Shanghai and Guangzhou. The top 10 national blockchain platforms show that Bitmain, Babbitt/Blockyuan and Huobi occupy the top three positions. The top 10 blockchain platforms are mainly concentrated in Beijing. Most of them were launched relatively early, with many episodes in 2016. years ago. Generally speaking, the development of blockchain has driven the development of related industries and set off a wave of entrepreneurship. Blockchain-related companies are mainly concentrated in Beijing, Shanghai and Guangdong, which is affected by the high barriers to blockchain technology. Beijing is rich in talent resources and has a good entrepreneurial environment. Shanghai has a unique financial status and has the greatest possibility of incubating the most successful companies in blockchain applications. Guangdong has a strong entrepreneurial atmosphere, which can attract related entrepreneurs. and promote the implementation of relevant enterprises. In addition, Hangzhou also benefits from its excellent Internet financial industry, and the blockchain industry is performing well. With the development of blockchain, related companies will appear in more cities. The popularity of blockchain continues unabated, and a large number of related public accounts have been spawned.It can be seen from the top 10 most influential WeChat public accounts that the number one “Digital Currency Trend Madman” is estimated to have more than 800,000 active fans in the past seven days, and the number two “Wang Tuanzhang Blockchain Diary” is estimated The number of active fans is also close to 500,000, and "Bi Lao Ye", who is estimated to have close to 400,000 active fans, is close behind, ranking third. The increase in public accounts also shows that more and more people are paying attention to the blockchain industry. Blockchain is becoming more and more popular. The average salary for related positions was 23,800 yuan before November 2017. By 2018, the average salary had reached 25,800 yuan. According to the skill demand chart for blockchain positions, it can be seen that the most important ones are commonly used development languages ​​(Go, C++, Java). In addition, you also need to have sufficient understanding of cryptography, formula algorithms, smart contracts, etc. In addition, There are also positions with relatively low thresholds such as operations. In general, the talent gap in the blockchain industry is relatively large. Blockchain technology is considered to be the fifth core technology most likely to trigger a disruptive revolution. After experiencing periodic chaos and bubble periods, it will gradually get on the right track with the intervention of national policies and the implementation of relevant regulations. , develop in a healthy direction. Blockchain will inevitably produce bubbles when it develops, but these bubbles will gradually become controllable with the healthy development of blockchain. The development prospects of blockchain and the innovations it can bring are unpredictable. From now on, leave this stage to it and watch its performance.

Industry overview

1. Definition

In a narrow sense, blockchain is a chronological A chained data structure that combines data blocks in a sequential manner and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

Blockchain is not a single technology, but a combination of new technologies. Each of these technologies performs its own role, solves different problems, and is combined to form a blockchain. As the basic structural unit of the blockchain, the block consists of two parts: the block header and the block body containing transaction data.

2. Industry chain analysis: The downstream industry covers a wide range

The upstream of the blockchain industry chain is mainly the underlying technology and infrastructure. The underlying technology includes core basic components, protocols and algorithms. Represented by Bitcoin, Litecoin, and Ethereum, a network environment such as distributed algorithms, digital keys, data storage, P2P network protocols, and consensus mechanisms based on blockchain technology, transaction rules, and incentives for miners to join network nodes have been built. Mechanism, representative companies include Xiaoyi, Quantum Chain, Wanxiang Blockchain, etc.; the infrastructure is mainly mining machines.

The midstream is the platform layer, which mainly provides developers with applications based on blockchain technology.
