『一』What is the future prospect of blockchain
Looking forward to the innovative development and technological changes of blockchain technology, we need to maintain a prudent, objective, rational and pragmatic attitude. Neither can we take it for granted that blockchain can be applied in all financial scenarios because of its revolutionary and disruptive nature; nor can we stop moving forward because the current technology is immature and lacks the constraints of industry standard consensus.
Blockchain can effectively solve the pain points and problems in complex scenarios with long business chains, many participants, and severe information asymmetry in the traditional financial field, but it is not suitable for some unilateral and high-frequency financial businesses. .
Therefore, the development of blockchain technology is not to completely replace the existing Internet underlying protocols and financial infrastructure, but to selectively develop in parallel according to applicable conditions, while constantly solving the inherent problems that exist in the initial stage. In the process of natural technological defects, we are facing the picture of social evolution brought about by technological change.
As the underlying technology of future financial technology, blockchain has strong strategic significance. In terms of future exploration of financial technology, the domestic financial industry should strengthen top-level design, accelerate the development, practice and application of blockchain technology, actively participate in international cooperation in blockchain finance and the creation of international blockchain alliances and standards, in order to strive for international The commanding heights of financial strategy, enhance my country's financial core competitiveness, and enable finance to better serve the real economy.
Difficulties in the development of blockchain
Blockchain technology is still in the early stages of development, and its application in various industries, especially the financial field, has not yet been fully realized. There are many problems and difficulties.
First of all, there is a lack of unified technical standards. The underlying technology of blockchain is immature and not yet unified, and most platforms still lack performance and security.
Secondly, there is a lack of reliable cases in practice. Although the current largest blockchain application, Bitcoin, has a maximum market capitalization of over US$300 billion, further testing of blockchain technology is needed if it is to carry large-scale transactions worth trillions of US dollars per day.
Thirdly, the replacement cost of the platform is relatively high. For traditional financial institutions, the investment cost of infrastructure for blockchain technology application is too high, and the risk of migrating original business to a new platform is relatively high, so institutions are not very willing to start over.
Finally, there is a lack of talent resources. The market lacks cross-border talents who understand both finance and blockchain, and domestic blockchain technology reserves and innovations as well as the development of related industries require a large number of comprehensive talents.

Introduction: Block Chain technology has the potential to become a widely used breakthroughSexual technologies, like the steam engine, electricity, or the Internet, change the way entire societies and economies function. Blockchain is a distributed (decentralized) digital network that enables users to exchange value or safely share data - including financial assets and contracts - in a secure environment. Through careful design, blockchain embeds trust into every transaction and every shared data, thereby greatly improving the security and efficiency of transactions and optimizing the account reconciliation process.
Accenture China's "Perspective (Blockchain)" focuses on the theme of blockchain and explores the advantages of blockchain technology in improving corporate operational efficiency and simplifying basic corporate processes. Financial companies The experience in blockchain technology can be used in other industries and enterprises, and the bright application prospects of blockchain technology in China are also worth looking forward to.
『三』Blockchain technology development status and prospects
Blockchain technology development status and prospects
Blockchain technology originated in In 2008, a scholar with the pseudonym "Satoshi Nakamoto" published a foundational paper "Bitcoin: A Peer-to-Peer Electronic Cash System" 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 users to create advanced smart contracts, currencies or other decentralized applications; Safe and trustworthy: Blockchain technology adopts The principle of asymmetric cryptography encrypts data, and at the same time uses the powerful computing power formed by consensus algorithms such as workload proof of each node of the distributed system to resist external threats.It can prevent external attacks and ensure that the 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 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 is represented byThe issuance process of digital currency generated by a distributed network system 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 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. districtAs 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. 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, so as to realize the transformation from the current "automated" contracts toA leap forward 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 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.This computational experimentation process obtains and executes optimal decisions 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.
『四』Blockchain Graduation Project Proposal
Background of the project research:
With the development of modern technology and information industry, at this stage, The fourth 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.

『撒』 What earth-shaking changes will blockchain bring and how will it change life
In addition to being used in the financial industry, blockchain is also used in other fields. In fields such as law, retail, Internet of Things, and medical care, blockchain can solve trust problems, no longer rely on third parties to establish credit information sharing, and improve the operating efficiency and overall level of the entire industry. Extremely high productivity will connect all people and machines in this society into a global network, and mankind will accelerate towards an era where goods and services are almost free. Perhaps by the second half of the 21st century, capitalism will decline and areas The decentralized collaborative sharing model of the blockchain will replace it and become the new model that dominates economic life.
Blockchain is the best technical means for this new collaborative sharing model. The infrastructure of blockchain allocates global resources in a decentralized manner, making blockchain an ideal technical framework for promoting social and economic development. The operational logic of blockchain lies in its ability to optimize peer-to-peer resources, global collaboration, and the sensitivity that fosters and encourages the creation of social capital in society. Establishing various platforms for blockchain can encourage a collaborative culture to the greatest extent, which complements the original shared model and will make it the decisive economic model of the 21st century.
