『一』A paper on the prospect analysis of blockchain in the financial field

A paper on the prospect analysis of blockchain in the financial field

Blockchain technology Born in 2008, the first application was Bitcoin. Blockchain technology uses a decentralized consensus mechanism to maintain a complete, distributed, and non-tamperable ledger database, allowing participants in the blockchain to implement a unified ledger system without establishing a trust relationship. . In 2015, many mainstream financial institutions in Europe and the United States recognized the application prospects of this technology and explored the application of blockchain technology in the financial field. The International Monetary Fund pointed out in a report that "it has the potential to change finance." Some people believe that blockchain technology will change human society as profoundly as double-entry accounting and shareholding.

Blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources. It will also promote the improvement of the existing financial system and financial rules, and build a shared and win-win situation. type of financial development ecosystem. The emergence of blockchain technology is a revolution in human credit creation. It allows both parties to the transaction to carry out economic activities without the need for third-party credit intermediaries, thereby achieving low-cost value transfer. It can be said that blockchain technology is a more efficient value exchange technology in the Internet era. The Internet has evolved from an information Internet that transmits information to a value Internet that transfers value. This is conducive to traditional financial institutions taking advantage of the opportunity to transform and transform endogenous businesses. Processes and application scenarios are Internetized.

1. Characteristics and shortcomings of blockchain

(1) Main characteristics of blockchain

(1) Decentralization. In the blockchain, there is no centralized hardware or management organization. The distributed structure system and open source protocol allow all participants to participate in the recording and verification of data, which is then sent to various nodes through distributed propagation. Each participant The nodes are all "self-centered", and the rights and obligations are equal. Blockchain is not simply decentralized, but multi-centered or weakly centered. When the Internet of Things makes it possible for all individuals to become central nodes, the central status of traditional financial intermediaries changes, transforming from a monopoly-type, resource-advantaged center and strong intermediary to an open platform, becoming a service-oriented multi-center. Center of differentiation.

(2) To trust. From a trust perspective, blockchain uses a set of open and transparent mathematical algorithms based on consensus specifications and protocols to enable all nodes to automatically and securely exchange data in a trustless environment. Blockchain essentially solves the problem of trust through mathematical methods. All rules are expressed in the form of algorithmic programs. Participants do not need to know the credit level of the counterparty, and do not need transaction endorsement or guarantee verification from a third-party institution. They only need trust. A common algorithm creates credit, generates trust, and reaches consensus for participants through the algorithm.

(3) Timestamp. A block is a number within a period of timeGenerated by packaging data and code, the header of the next block contains the index information of the previous block, and a chain is formed by connecting the end to the end. The blocks that record the complete history and the chain that can be completely verified form a timestamp that can trace the complete history. It can provide retrieval and search functions for each piece of data, and can use the blockchain structure to trace the source, one by one. verify. Therefore, the blockchain is timestamped when generated, forming a database that cannot be tampered with or forged. Modifications to the database on a single node are invalid unless more than 51% of the nodes in the system can be controlled at the same time, so the data reliability of the blockchain is very high.

(4) Asymmetric encryption. Blockchain uses an asymmetric encryption algorithm, that is, a "key pair" is used in the encryption and decryption process. The two keys in the "key pair" have asymmetric characteristics. In the application scenario of blockchain, on the one hand, the key is the public key visible to all participants. Participants can use the public key to encrypt a piece of authenticity information, and only the owner of the information can use the private key to decrypt it. On the other hand, the private key is used to sign the information, and the signature is verified by the corresponding public key to ensure that the information was sent by the real holder. Asymmetric encryption minimizes friction boundaries in value exchange, enables transparent data anonymity, and protects personal privacy.

(5) Smart contract: Since the blockchain can realize point-to-point value transfer, corresponding programming scripts can be embedded during transfer. This smart contract method is used to handle some unforeseen transaction patterns and ensure Blockchain can continue to be effective. This kind of programmable script is essentially a list of many instructions to achieve pertinence and conditionality in value exchange and to achieve specific uses of value. Therefore, any value exchange activity based on the blockchain can achieve hard control over its use, direction and various restrictions through intelligent programming, eliminating the cost of soft constraints by law or contract.

(2) Main problems of blockchain

(1) High energy consumption problem. There is an impossible triangle in the traditional currency and banking system, that is, it is impossible to achieve decentralization, low energy consumption and high security at the same time. The impossible triangle also exists in the construction of blockchain. For example, in the actual application of Bitcoin, its development has brought about the rapid expansion of computer hardware, and the main costs in the "mining" process have shifted to hardware costs and electricity costs. Therefore, after applying blockchain technology to achieve equity cost benefits, maximizing its technical efficacy has become an urgent problem to be solved.

(2) Storage space problem. Since the blockchain records every transaction information from the initial information in the system, and each node has to download, store and update data blocks in real time, if the data of each node is completely synchronized, the network pressure will be great, and each node will The storage space capacity requirements of each node may become a key issue restricting its development.

(3) The problem of stress resistance. The system built based on blockchain follows the barrel theory and must take into account the worst processing speed and network environment among all network nodes. Therefore, if blockchain technology is promotedIts overall ability to withstand pressure in large-scale trading environments has yet to be verified. If the transaction volume generated per second exceeds the design capacity of the system (the weakest node), transactions will automatically enter the queue and be queued, resulting in a poor user experience.

2. Application of blockchain in the financial field

(1) Financial infrastructure

Blockchain may be used as the infrastructure of the Internet in many fields. All show broad application prospects. In the financial industry, blockchain technology will first affect financial infrastructure such as payment systems, securities settlement systems, and transaction databases. Later, the technology will also expand to general financial services, such as credit systems, "anti-money laundering," etc. This is because, based on the characteristics of blockchain technology, it will first enter the infrastructure field with high trust requirements and high cost of traditional trust mechanisms. In the past, infrastructure was a public product, but new technologies and new systems of blockchain have made it more It is possible for multiple people to participate in the provision of public goods. The future of Internet finance will use Internet technologies such as blockchain to transform the core production systems of traditional financial institutions and build financial enterprises on the Internet.

The current information Internet can be collectively referred to as the TCP/IP model, and HTTP is the most important application protocol in the application layer. In the Internet of Value, blockchain is a point-to-point transmission protocol in the application layer. Its value is the same as that of the HTTP protocol in the information Internet. The huge potential and prospect of blockchain is that it can reconstruct the infrastructure and core production systems of the traditional financial industry, not just at the application level such as APPs. This is because, at the network level, the blockchain is based on the IP communication protocol and the distributed network; at the data level, the blockchain database system is brand new and is significantly better than the existing one. There is a database of the financial system; at the application level, registration and settlement, clearing systems, smart contracts, and the Internet of Things based on the blockchain can greatly improve efficiency. Financial activities on the blockchain are programmable finance. .

(2) Digital Currency

From the perspectives of security and cost, it is a general trend that banknotes will be replaced by new technologies and new products. The establishment of digital currency issuance and circulation systems is very necessary for financial infrastructure construction and economic development. Following the integration of traditional currency and digital currency, the issuance, circulation and trading of digital currency should be led by the central bank, reflecting convenience and security, and achieving a balance between protecting privacy, maintaining social order, and combating illegal and criminal activities. It is conducive to the effective operation and transmission of monetary policy. It is necessary to retain the control of monetary sovereignty. Digital currency is freely convertible and controllable.

The success of blockchain technology on Bitcoin proves the feasibility of programmable digital currency. Research from the Bank of England suggests that central banks could consider issuing blockchain-based digital currencies, which could increase financial stability. The technical route of digital currency can be divided into two types: account-based and non-account-based. They can also be used in layers to try to coexist.. The characteristic of blockchain technology is distributed bookkeeping, which is not account-based and cannot be tampered with. If the digital currency focuses on protecting personal privacy, this technology can be used. However, the current blockchain occupies too many computing resources and storage resources and cannot cope with the current scale of transactions. This problem needs to be solved before it can be promoted and applied.

(3) Self-finance

From the perspective of services and non-monetary creation, modern finance is realized through intermediaries. In the Internet era, it is possible to achieve direct finance in the true sense of disintermediation. However, this possibility is not complete. The main reason is that the current Internet finance is based on the original finance and cannot be jumped out. Blockchain technology provides a possibility. Blockchain can be divided into public blockchain and private blockchain. Public blockchains are like Bitcoin. Once the protocol is approved, it becomes an integral part of the blockchain. Private blockchains still need to be permissioned, and blockchain technology in banking systems requires auditing of each participant. Private blockchain is very similar to a form of self-finance, and public blockchain is more similar to the support and guarantee for the bottom layer of private blockchain. When blockchain technology is widely used and third-party financial management technology is generally available, self-financing based on blockchain technology will become completely possible.

3. Blockchain Application and Financial Supervision

Blockchain technology is currently the only tool that can be used to record and prove transaction consistency and company financial accuracy without the need for a third party. Therefore, it can meet the requirements of potential regulators and the public for audit effectiveness, accuracy and timeliness, and has broad application prospects in the financial field. However, its development is still restricted by the current system. On the one hand, blockchain has had an impact on the current system because its decentralized and autonomous characteristics dilute concepts such as the state and supervision. For example, digital currencies represented by Bitcoin challenge the country's right to issue currency and regulate monetary policy, causing monetary authorities to take a conservative attitude towards the development of digital currencies. On the other hand, regulatory authorities also lack full understanding and expectations of this new technology, and the establishment of laws and systems will be seriously delayed, resulting in the lack of necessary institutional norms and legal protection for blockchain applications, increasing the risks for market entities.

Once blockchain financial technology is widely deployed in the financial industry, the de-financial nature of supervision will occur, and supervisory functions, supervisory methods and supervisory means will be redefined. For example, if securities lending, repurchases, and margin trading can be traded through the blockchain, regulatory authorities can consider using the information from this public ledger to monitor systemic risks in the market, which is not only efficient but also reliable. From a macro-financial perspective, after the emergence of the financial era, the currency creation and transmission mechanism and the credit creation pattern will change. From a micro-finance perspective, with the further development of blockchain technology, finance and business have become difficult to distinguish, and will transcend the meaning of separate and mixed industry supervision. The reform of the financial supervision system needs to be discussed from this perspective.

BlockchainThe "decentralization" brought about by technology still requires centralized departments to provide regulatory and guarantee support. Regulators can proactively embrace new technologies in Internet finance. U.S. Securities and Exchange Commission member Kara Stein believes that regulators need to be in a leading position, taking advantage of the advantages of blockchain technology and quickly responding to its potential weaknesses. For example, blockchain technology hopes to break privileges and human manipulation and allow computer algorithms to achieve "free credit notarization." But in practice, due to the lack of supervision, digital currency transactions such as Bitcoin face high risks of speculation and money laundering. Therefore, the application of blockchain technology requires regulatory authorities to formulate relevant standards and specifications to ensure that financial innovative products are used appropriately. At the same time, it is necessary to improve the protection of consumer rights and interests, strengthen education on the protection of financial consumer rights and interests, and improve consumers' awareness of risk prevention.

『II』 What are the possible application fields of blockchain? What are the application fields of blockchain technology?

1. Financial field. Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

2. Internet of Things and logistics fields. Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered to be a promising application direction of blockchain.

『三』What are the application fields of blockchain technology?

Application fields: financial field, Internet of Things and logistics field, public service field, digital copyright field, insurance field, public welfare field .

Blockchain can also be naturally combined in the fields of the Internet of Things and the field of mold grinding and cavity flow. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

Blockchain is closely related to people’s production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

『五』Blockchain Graduation Project Proposal

Background of the project research:

With the development of modern technology and information At this stage of industrial development, the fourth industrial revolution is beginning to take shape. The world is about to enter a technological era with new technologies such as the Internet and artificial intelligence as the core. At the same time, blockchain technology has emerged as the times require and has become an important factor for many international governments and industries. Hot topics of concern. 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.

The main content of the research: This topic mainly includes the following three aspects:

[if !supportLists] 2. [endif] Make a public welfare inquiry webpage based on blockchain technology

[if !supportLists] 3. [endif] Application issues and explanations of the query system

The purpose of the research:

The scale of my country’s public welfare continues to develop and expand , then our shortcomings were also exposed, including lack of credibility and lack of management of charitable organizations. The use of blockchain technology can solve this problem. This technology will track and store data and behaviors throughout the donation process, realize the complete disclosure of the public welfare chain, enable donors to effectively supervise, avoid shortcomings such as low efficiency and clear fund flows, and control risks for public welfare projects, improving Credibility and transparency of public welfare projects promote the development and progress of public welfare projects and enhance trust between people. According to the attributes and characteristics of the blockchain system, public welfare enterprises can implement full-cycle tracking, evidence storage and auditing of data and behaviors in the public welfare process, so that all parties involved in public welfare projects can conduct full-process tracking and effective supervision of the project, avoiding Due to the shortcomings of artificially reducing efficiency in public welfare, it provides a rational method for public welfare projects to control risks and judge effects, improve the transparency of public welfare undertakings, and promote the development of public welfare.

Significance of the project research: This project intends to develop an open and transparent system for tracking public welfare donations based on blockchain technology and combined with the actual development of public welfare undertakings in my country. Through in-depth analysis of blockchain technology and charity business, we found that blockchain technology has natural advantages in solving the problem of public welfare transparency. Blockchain technology can be understood as a distributed accounting method that can record all transaction information and ensure that it cannot be tampered with. This determines that wherever justice, fairness, and integrity are required, blockchain has great technology. Room to play. At the same time, the addition of smart contracts directly solves the business problem of earmarked funds.
