㈡ What is the current overall development of blockchain

Current status of blockchain development in China

1. The industry is in a stage of rapid growth

From the blockchain industry level, from 2016 to 2018, as domestic large-scale IT Internet companies have deployed blockchain, start-ups have entered a blowout mode, and the scale of the blockchain industry has continued to expand. According to IDC data, the market size of China's blockchain industry has grown from US$85 million in 2017 to US$561 million in 2020, with a compound annual growth rate of 60.3%.

㈢ What are the prospects for the future development of blockchain

Shared from District View Network: In 2018, blockchain stick AI became the most popular technical term , more and more technology companies have announced their entry into the blockchain market. On the Internet, companies such as Xunlei, Renren, Baofeng, Tianya and other companies have made blockchain-related actions. These companies have the same fate. They have all experienced prosperity, but after the impact of the Internet entrepreneurship wave, they began to decline, and then they caught up with the hot spots of blockchain and started to develop.Started trying to counterattack.
Investment in the global blockchain industry is booming
According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, as of the end of April 2017, there were a total of 455 companies worldwide The blockchain company has received a cumulative financing amount of US$1.947 billion. Among them, the total investment and financing of U.S. blockchain-related companies is as high as 1.252 billion U.S. dollars, accounting for 64.3% of the global market; the total financing amount of Chinese blockchain emerging companies is approximately 114 million U.S. dollars, accounting for 5.86%, ranking second only to the United States in the world Second, it is growing rapidly.
The current overall survival status of the blockchain is good, with a survival rate of 87.25%. 47
of all the invested companies have been closed down, accounting for about 10.51%, and another 10 companies have been acquired. Due to changes in the competitive landscape of the Bitcoin market, some companies have been forced to close down. At the same time, some companies in the currency circle have gradually transformed into chain companies
Exploration at the national level has also begun. On March 23, the Department of Information Technology and Software Services of the Ministry of Industry and Information Technology announced that it would study and explore the application of blockchain in the industrial field. Previously, the Ministry of Industry and Information Technology stated that it was preparing to establish a national blockchain and distributed accounting technology standardization technical committee to explore the formation of a complete blockchain standard system to better serve the development of the blockchain technology industry.

5 Foreign banks are experimenting with "blockchain technology", is it still far from subverting the financial industry?

Although blockchain technology has many benefits, it will also make financial institutions no longer able to use funds through The reinvestment model during the turnover period is the reason why many financial institutions are on the sidelines.
In China, the same topic is continuing. On January 20, 2016, the Digital Currency Seminar of the People's Bank of China announced the initial results of digital currency research and stated that the central bank is exploring the issuance of digital currency, and blockchain technology is the core behind it.
In the future, we feel that not only digital currency, but also blockchain technology will play a huge role in crowdfunding, P2P, securities and other fields, playing the role of a "disruptor".
However, many blockchain applications with promising applications have emerged in the world, such as Ethereum and the decentralized content publishing platform DECENT.

Industry technology research process continues to advance

In recent years, the global blockchain technology research process has accelerated, and the number of industry patent applications has increased rapidly. According to SOOPAT statistics, from 2014 to 2018, the number of global blockchain patents continued to rise. By 2018, the number of global blockchain patent applications had reached 2,966. Among them, the number of blockchain patents in China in 2018 increased from 33.33% in 2014 to 82.1% in 2018.

However, although global blockchain technology has been continuously developing and innovating in recent years, there is currently no universal evaluation standard and system that can evaluate the technical performance, efficiency and scalability of blockchain. Detailed specifications on issues such as sex and safety. Overall, blockchain technology awaits further breakthroughs.

China’s blockchain technology tends to serve applications

< p> In terms of technical direction, the core of China’s blockchain technology is to serve physical applications, while American blockchain technology is still solving potential problems of blockchain, which has led to the domestic focus on alliance chain applications and the hope of optimizing blockchain technology to meet the needs of high-concurrency applications; foreign countries focus on the application of public chains and carry out optimization and innovation of core technologies based on the characteristics of public chains. In terms of application, domestic blockchains focus on service industry applications and tend to be “coinless blockchains”; in the United States, most are public chains and tend to circulate digital assets.

㈦ What is the impact of blockchain on the world economy?

In just a few years, blockchain has developed from the 1.0 era to the 3.0 era, and each "era" update has It has brought changes to the world. The development of blockchain can be divided into three stages from blockchain era 1.0 to 3.0: peer-to-peer transactions, smart contracts and blockchain application ecology (Token economy)
Block Chain 1.0 era: digital currency return rate is king

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

Blockchain 3.0: for business Its subversion lies in its transformation of production relations

All obstacles to the development of human society are fundamentally caused by "mutual distrust", especially various economic and financial crises. If humans can solve the problem of mutual trust, then humans will complete a very big leap.
The development of blockchain has gradually laid the foundation for this direction. Humanity is entering the era of "smart contracts". This is the process of upgrading human trust mechanisms. Once smart contracts are reached, human society will face a new major upgrade. , as each person is a value creator, the value he creates can be accurately recorded and rewarded accordingly. There will be less and less interference between everyone, and people are truly moving towards independence and equality. Human civilization has evolved from an "identity society" to a "contract society", and blockchain is expected to lead mankind to transition from a "contract society" to a "smart contract" society.
Although blockchain has moved out of the conceptual stage, the current status of blockchain technology development is that the underlying technology is not mature enough and the 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, it can be said that the entire domestic trend is waiting for the emergence of a super-powerful blockchain project.

㈧ 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 system can participate in the verification process of data blocks (such as the "mining" process of Bitcoin), and select specific nodes through a consensus algorithm. Nodes add new blocks to the blockchain; Programmable: Blockchain technology can provide a flexible script code system to support user creationBuild advanced smart contracts, currencies or other decentralized applications; Safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, while relying on the powerful consensus algorithms such as workload proof of each node in the distributed system. It uses 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 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, which 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 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 widely used in economic, financial and social systems.application scenarios. 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 application of blockchain in high-frequency trading scenarios in most financial systems. The PoW consensus process is highly dependent on the computing power contributed by the blockchain network nodes. These computing power are mainly used to solve SHA256 hashing and random number searches. Otherwise, they do not generate any actual social value.Therefore, in a general sense, these computing resources are considered to be "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) and even Decentralized Autonomous Society (DAS) become possible. The main development trend of blockchain and smart contract technology is from automation to intelligence. Most of the existing smart contracts and their applications’ essential logic are still based on the “IF-THEN” type of predefined scenarios.Conditional response rules 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 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 be formed by participating in various forms of Dapp.DAC and DAO formed a specific organizational form, and finally formed DAS, the artificial society in ACP. 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.

Background of the project research:

With the development of modern technology and information industry, at this stage, the fourth The second industrial revolution is beginning to take shape, and the world is about to enter a technological era centered on new technologies such as the Internet and artificial intelligence. At the same time, blockchain technology has emerged as the times require and has become a hot topic of concern to many international governments and industries. Blockchain technology has been regarded as the core technology with the greatest potential to trigger the fifth round of disruptive revolution after steam engines, electricity, information and Internet technology. In the past 10 years, with the strong support of the government and policies, the development situation of my country's philanthropy has been relatively optimistic. However, as the scale of charity continues to develop and expand, my country's public welfare undertakings have gradually revealed some shortcomings. The biggest problems existing in traditional public welfare undertakings are insufficient credibility, imperfect internal management of charitable organizations, and high costs. However, many Internet public welfare service companies are currently actively using the new technology of blockchain to solve this problem. Blockchain technology has the characteristics of decentralization, information traceability and non-tampering, openness and transparency, and smart contracts. It can make up for the shortcomings of traditional public welfare undertakings such as opaque information and low management efficiency. Blockchain technology will enter public welfare undertakings and will Bring new development opportunities to the charity industry.
