⑵ Blockchain technology development status and prospects

Blockchain technology development status and prospects
Blockchain technology originated in 2008 under the pseudonym "Nakamoto Satoshi Nakamoto’s seminal paper “Bitcoin: A Peer-to-Peer Electronic Cash System” was published on the cryptography mailing group. 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: Blockchain uses a chain block structure with timestamps to store 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 systemAll nodes can participate in the verification process of data blocks (such as Bitcoin’s “mining” process) and select specific nodes to add new blocks to the blockchain through a consensus algorithm; Programmable: Blockchain technology can provide flexibility A script code system that supports users to create advanced smart contracts, currencies or other decentralized applications; Safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, while leveraging the workload of each node in the distributed system The powerful computing power formed by consensus algorithms such as proofs can 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 Algorithm; 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 contracts, and is the programmable feature of the blockchain. The foundation; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamp, the consensus mechanism of distributed nodes, the economic incentives based on consensus computing power andFlexible and 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 credit endorsement by a central institution, thereby realizing "financial disintermediation" to a large extent; at the same time, blockchain can be used 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 partially solve this problem, 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 use of the blockchain in mostApplication in high-frequency trading scenarios in 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 among 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 Decentralized Autonomous Society (DAS) 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 centralized social systems, 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 can be naturally 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 features of distributed social systems.Modeling in which each node will act as an autonomous and autonomous agent in a distributed system. 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.

⑶ How blockchain technology empowers real industries

Now there are domestic companies that have implemented blockchain technology into actual industries. For example, Wanglian Technology has put blockchain technology into practice. The chain is applied to financial services, medical health, IP copyright, Internet of Things, sharing economy, communications, education,
social management, charity, culture and entertainment and other fields

⑷ China’s Blockchain in 2021 What is the development trend

Looking forward to 2021, the top-level design of my country’s blockchain will be further improved, application standards for various industries will be gradually established, and the development direction will move from technology leadership to market penetration; blockchain integration applications in finance , supply chain, government affairs and other fields have begun to be implemented, and the industrial scale will show rapid growth. However, many problems currently faced by the development of blockchain in our country still need to be focused on and started to be solved or alleviated in 2021. For example, the independent innovation capabilities of core technologies still need to be further strengthened, security issues and talent gaps need to be improved urgently, and integrated applications The scene still needs to be explored in depth. Therefore, CCID Research Institute proposed to accelerate the construction of the blockchain ecosystem, improve standards and regulations, improve the supervision system, strengthen the independent innovation capabilities of core technologies, promote the coordinated development of blockchain and other new technologies, and vigorously cultivate professional talents to achieve The blockchain industry is developing healthily.
Yibaoquan has been committed to the research and development and application independent innovation of blockchain since 2014. It is a blockchain electronics company that has maturely used blockchain technology to solidify and store electronic data and has been recognized by judicial authorities. Data storage and security agency. Through the pioneering "blockchain + judicial + application" model, with blockchain technology as the underlying technology and electronic data storage and preservation as the basis, we have launched intellectual property protection (micro-copyright), electronic contract signing (gentleman signature), Internet Notary System (Zhongzhengbao) has three application layer brands.
E-Baoquan jointly launched the "Preservation Chain" open platform together with the Notary Office, Arbitration Commission, Copyright Protection Center, CA Organization, etc. At the same time, it has connected with the Guangzhou Internet Court and the Supreme CourtA judicial chain involving more than 30 courts led by the Law of the People's Republic of China. Continuously improving the "blockchain + judicial" ecosystem, Yibaoquan can provide one-stop blockchain security services such as evidence collection, evidence storage, and certificate issuance for different groups.
Currently, it has obtained 15 independent invention patents, 27 copyrights, ISO 27001 information security system certification, Ministry of Public Security Level 3 certification, national double-high enterprise, and the 2018 National Ministry of Industry and Information Technology Industrial Internet Pilot Demonstration Project (the only Blockchain selected projects), and one of the first batch of domestic blockchain information service registration companies by the State Cyberspace Administration of China in 2019.

⑸ What is the prospect of blockchain and where is the future?

Prospects: A series of actions at the national level in China are enough to say that global blockchain standards will be dominated by China in the future. This is a huge goal for China. After China missed the right to speak in the Internet, it can no longer miss the right to speak in the blockchain. At present, China has the most blockchain projects besides the United States. As early as 2019, reports pointed out that China controls two-thirds of the world's encryption computing power. The Cryptozoology Law that China has voted to pass is also a careful layout for China to master blockchain standards. In the near future, this is an inevitable result. This means that if Chinese college students participate in the construction of this field, they will be able to take advantage of national policies, participate in the construction of the world's top industries, and become the main force in building this industry!
Future Judgment: There is no doubt that the support of national policies will be followed by the crazy pursuit of the capital market. In fact, this can be referred to the development history of the Internet. Any emerging sunrise industry will become the target of capital pursuit. How capital originally competed for the Internet, now the same drama will be staged for the blockchain.
It is recognized that the biggest application scenario of blockchain is the financial industry, because the biggest attribute of Bitcoin with the birth of blockchain is financial attribute. The use of blockchain technology in government affairs systems can solve many service difficulties and information flow, saving more costs and time. Therefore, piloting in these two industries is in line with the characteristics and needs of blockchain.
In addition, as blockchain technology continues to mature, in addition to these two industries, blockchain will quickly penetrate into all walks of life and solve industry pain points, such as: the game industry, solving game asset property rights issues; manufacturing industry, to solve the problem of fake brand supply; the medical industry, to solve the problem of medical file exchange; the financial industry, to solve the problem of rapid cross-border payments; students with a financial major background will be the first group to enjoy the employment dividends of the industry, and then follow As the technology matures, students regardless of professional background will be able to participate. However, students with traditional professional backgrounds also seriously lack blockchain-related knowledge. If they want to enjoy the dividends, they must supplement blockchain knowledge.

⑹ What is the current status of China’s blockchain industry

China’s blockchain industry has developed rapidly in 2019, which is mainly reflected in the following points:

First, the country’s high-level strategic guidance and support create a good policy environment. According to incomplete statistics, in the first half of 2019, more than 23 provinces and cities across the country released more than 112 pieces of policy information involving blockchain. High-level government officials emphasized that the application of blockchain technology plays an important role in technological innovation and industrial transformation, and supported the accelerated development of blockchain technology and industrial innovation.

In addition, market supervision policies regarding blockchain have also gradually improved. On the one hand, strict vigilance and testing are carried out for virtual currency transactions and services; on the other hand, related industries with blockchain applications The regulatory system is also being further constructed and improved to provide a strong guarantee for industrial blockchain projects to deeply serve the real economy. The market has become more standardized and the industrial environment has gradually become clearer. In addition, support for technological breakthroughs and talent encouragement has also been provided through the establishment of blockchain Industrial parks, blockchain special investment funds and other means will subsidize technological innovation and talent introduction to promote the development of the blockchain industry.

Second, domestic enterprises actively participate in the research and development and application of blockchain technology and carry out blockchain strategic layout. For example, e-commerce giants such as Alibaba use blockchain technology in areas such as product traceability and cross-border settlement. JD.com uses a transparent supply chain system to combat counterfeit and shoddy products. Tencent focuses on the development of applications in financial fields such as electronic invoices.

⑺ What is the overall situation of the blockchain?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. When paying attention, you must make a multi-faceted comparison. First of all, you must choose according to your needs. You must also pay attention to the team's strength and effectiveness. You know that Baker Chain is doing a good job in blockchain. You can consult first
