Introduction In recent years, the widespread attention and development of blockchain technology and smart contracts in the financial industry have been notable. The origins of blockchain technology can be traced back to the publication of the Bitcoin whitepaper by Satoshi Nakamoto in 2008, where the technology was initially used to record the underlying data structure of Bitcoin transaction records. With the evolution of the Bitcoin system, blockchain technology has gradually demonstrated broad application prospects in finance, credit reporting, auditing, and various other fields due to its decentralized, tamper-resistant, and transparent nature [1]. Smart contracts, as a key application of blockchain technology, automatically execute contracts based on predefined terms and conditions, eliminating the need for third-party intermediaries and thereby enhancing transaction efficiency and fairness. The widespread application of smart contracts in the financial industry encompasses areas such as cross-border payments, supply chain finance, and equity financing [2]. The combination of blockchain technology and smart contracts not only enhances the transparency and security of financial transactions but also effectively reduces transaction costs and operational risks. Research indicates that by establishing decentralized financial services platforms, more convenient and cost-effective financial services can be provided to small and micro-enterprises and individuals, thereby driving innovation and high-quality development in the financial industry [3]. The application of blockchain technology and smart contracts in the financial industry has brought about profound technological changes, providing new impetus and safeguards for the efficient operation and sustainable development of financial markets. 2. Overview of Blockchain Technology and Smart Contracts 2.1. Basic Theory of Blockchain Technology Blockchain technology is a novel distributed ledger technology characterized by six key features: decentralization, global circulation, anonymity, public transparency, data immutability, and autonomy. This technology ensures the orderly cooperation of data across various network nodes to support its stable growth, forming a ledger consisting of a chain of blocks. These blocks are composed of a timestamp table and sequentially recorded data modules, guided by fundamental cryptographic techniques and machine theory. Zhao Xiaohui [4] believes that as blockchain technology becomes increasingly mature and refined, it has even surpassed some traditional fingerprint data block encryption storage applications and has been applied in industries such as finance. 2.2. Definition and Working Principle of Smart Contracts Smart contracts are automated contracts based on blockchain technology. They allow transaction parties to automatically execute contracts without the need for third- party intervention through preset terms and conditions. The working principle of smart contracts mainly depends on the decentralized, unalterable, and transparent characteristics of the blockchain. Specifically, smart contracts are deployed on the blockchain in the form of code, containing contract terms, trigger conditions, and execution logic. When the trigger conditions are met, smart contracts will automatically execute corresponding operations, such as transfers, data records, etc. This automatic execution feature eliminates the interference of human factors, improving the efficiency and fairness of transactions. 393 Smart contracts are widely used in the financial industry. They can be used in cross-border payments, supply chain finance, equity financing and securities issuance, the insurance industry, and many other fields. For example, in the field of cross-border payments, smart contracts can achieve automated fund clearing and settlement, improving payment efficiency and reducing costs; in the field of supply chain finance, smart contracts can help companies achieve automated financing and payment operations, improving the operation efficiency of the entire supply chain. 3. Application of Blockchain Technology and Smart Contracts in the Financial Industry 3.1. Cross-Border Payments and Settlements With the deepening of globalization, the demand for cross- border payments and settlements is increasing. However, traditional cross-border payment processes are cumbersome, costly, inefficient, and entail high risks. The introduction of blockchain technology and smart contracts has brought revolutionary changes to cross-border payments. By establishing a decentralized global payment network, blockchain technology can achieve real-time clearing and settlement of cross-border payments, reduce transaction costs, and improve payment efficiency. Additionally, the automated execution feature of smart contracts can ensure the fairness and security of transactions, reducing human interference. Payment settlement and clearing are the most fundamental financial activities, and blockchain technology was first experimented with in the banking industry in payment settlement. Modern commercial activities rely less on peer-to- peer cash transactions and more on financial intermediaries, such as commercial banks. Wen Shenghui [5 believes that the large number of modern commercial activities makes settlement and clearing cumbersome tasks for financial institutions, requiring error-free operations with enormous workloads, especially in the relatively more complex procedures of cross-border payments. Although from the perspective of the payer, the payment seems to be completed in seconds, the intermediary procedures are very cumbersome, often taking 2-3 days. Cross-border payments also incur high transaction fees and require trusted intermediary roles (correspondent banks). Compared with ordinary cross-border payments, the application of blockchain technology can bypass transit banks, which means reducing transaction costs and simplifying transaction procedures, reducing transaction costs, reducing intermediate links, and shortening the time for funds in transit; real-time monitoring can reduce regulatory difficulties and meet higher regulatory requirements; Blockchain distributed ledger technology improves transaction security; direct contact between payer and payee on the chain speeds up transactions. According to McKinsey's calculations, blockchain technology can reduce the cost of each cross- border payment business from 26 US dollars to 15 US dollars, of which 75% is the transit bank fee, and 25% is the foreign exchange conversion cost and compliance, error investigation cost. 3.2. Supply Chain Finance Supply chain finance is a specialized area of commercial bank credit business, premised on the trading relationships between core enterprises and upstream and downstream enterprises. It serves as a mutually beneficial bridge between core enterprises, banks, and upstream and downstream enterprises, allowing comprehensive information acquisition from the upstream and downstream enterprises. This transformation turns uncontrollable independent enterprise risks into controllable overall enterprise risks, thereby minimizing risks within a controllable range. The role of supply chain finance in addressing issues such as long receivables collection periods and inventory backlog is becoming increasingly significant. Song Hua et al. [6] suggest that leveraging the higher credit rating of core enterprises can alleviate the financial pressure and supply-demand imbalances in the flow of funds for "weaker" members, thereby solving the funding constraints faced by small and medium-sized enterprises. It is evident that the essence of the supply chain lies in controlling the four flows of the supply chain—namely, the flow of goods, commercial transactions, information, and funds—to help enterprises revitalize their liquid assets and thus resolve their financing issues. While gaining recognition and adoption by market traders, the development of supply chain finance is hindered by various drawbacks such as slow account receivable turnover, credit risks, and high operational risks. Ling Runzhe et al. [7] found that the integration of blockchain technology with supply chain finance can optimize the operational processes of supply chain finance, reduce transaction costs, and improve the risk control system. 3.3. Equity Financing and Securities Issuance The application of blockchain technology and smart contracts in the field of equity financing and securities issuance brings innovative solutions to the traditional financial industry. By building an equity financing platform based on the blockchain, decentralized and automated equity financing can be realized, reducing issuance costs and improving market efficiency. Smart contracts can automatically execute terms and conditions in equity financing, ensuring the fairness and legality of transactions. In addition, blockchain technology can also improve the transparency of securities issuance and trading, reducing the risk of market manipulation and fraud. In terms of equity financing, there are still many limitations in traditional technology, such as the equity financing and transfer transactions of unlisted companies need to manually review paper stock certificates, option issuance and exchangeable notes, etc. A large number of manual and paper- based operations not only easily cause many human errors, but also make it difficult to leave audit traces. Compared with this, the equity financing model based on blockchain technology can reduce human errors and enhance transparency and auditability. The distributed accounting method of blockchain technology replaces the original paper record method, allowing transaction parties to complete the approval of financing materials online. While ensuring high efficiency of equity financing, it also greatly reduces approval risks and improves transaction and management efficiency. In terms of securities issuance, Joshua [8] found that in the securities system, blockchain technology can incorporate the types of securities, qualification documents for admission, transfer restrictions, and other parameters into smart contracts through pre-programmed digital procedures. Leveraging the 394 unique advantages of decentralization and trustlessness inherent in blockchain technology, it facilitates the automation and intelligence of transactions between buyers and sellers. In 2015, after obtaining approval from the U.S. SEC, Overstock successfully issued securities publicly using blockchain. Onchain, using its own blockchain technology, provides services to enterprises. The company's Antshares consensus algorithm can be utilized in areas such as equity crowdfunding, digital asset management, and smart contracts. The application of blockchain in the securities industry can simplify the securities settlement process. Data and information generated from securities transactions require confirmation and clearing from central clearing institutions, banks, brokerages, and exchanges. The current settlement process is complex and prone to causing transaction delays, thus affecting the efficiency of securities trading. By employing blockchain technology, it is possible to conduct ledger recording and clearing and settlement work independently without the need for a third-party clearing institution. This fundamental change in business processes also plays a significant role in eliminating the netting settlement system and reducing settlement risk. Research by DTCC [9] has shown that compared to traditional securities trading models, the intervention of blockchain technology leads to a trend towards automated and intelligent transactions between buyers and sellers, simplifying the settlement process and mitigating settlement risk. With the impetus of blockchain technology, intermediary institutions in the securities market will no longer exist. Relative to the current securities trading process, blockchain technology has a significant impact on optimizing securities trading processes. 4. Advantages and Challenges of Blockchain Technology and Smart Contracts in the Financial Industry 4.1. Advantage Analysis The application of blockchain technology and smart contracts brings many advantages to the financial industry. First, they improve the transparency and fairness of financial transactions by building a decentralized trust mechanism. Traditional financial transactions often need to rely on third- party intermediary institutions for verification and settlement, which not only increases transaction costs but also reduces transaction efficiency. And blockchain technology, through distributed ledgers and consensus mechanisms, allows all participants to directly participate in the verification and recording of transactions, without the need for third parties, thereby improving the transparency and fairness of transactions. The key to the widespread attention garnered by blockchain technology in numerous fields lies in its unique advantages. Wang Faming and Zhu Meijuan [10] pointed out that the main advantages of blockchain technology include decentralization, collective maintenance, security, traceability, immutability, and openness. The core advantage of blockchain technology is decentralization, meaning that the entire network lacks a central core system, operating on a decentralized distributed architecture, thus saving a significant amount of intermediary costs in practical applications. Additionally, the asymmetric encryption and consensus algorithms of blockchain ensure the security, integrity, and traceability of data. Regarding the openness of blockchain technology, Lin Xiaochi et al. [11] believe that aside from the information of accounts and transaction parties, the remaining data in the blockchain system is open, allowing anyone to query data through public interfaces, thereby ensuring the transparency of data. In summary, the unique series of advantages possessed by blockchain technology enables it to be favored in more fields in the future. Its prospects for development and application scope are expected to be more substantial. Blockchain technology has been applied to various application scenarios such as transaction settlement in exchanges. Due to the advantages of multi-party participation, decentralization, and unalterability, blockchain technology not only helps exchanges optimize business processes and improve collaboration efficiency, but also helps exchanges strengthen the trusted system and promote data sharing. The operation mode of exchanges based on blockchain technology mainly includes securities issuance, derivative listing, trading, settlement, custody, and other scenarios. From the perspective of transaction flow, the application of blockchain technology in exchanges can be divided into three stages: pre-transaction, during transaction, and post-transaction. Secondly, the application of blockchain technology and smart contracts reduces the cost and risk of financial transactions. The automated execution feature of smart contracts reduces the need for human intervention, lowering the risk of operational errors and fraudulent behavior. In addition, the immutability and decentralization of blockchain technology also reduce the risk of transactions being tampered with or manipulated. Moreover, the application of blockchain technology and smart contracts also promotes innovation in financial services. By building a decentralized financial services platform, it can provide more convenient and low-cost financial services for small and micro enterprises and individuals. The flexibility and programmability of smart contracts also provide more possibilities for the innovation of financial products. 4.2. Contribute to Enhancing Regulatory Oversight in the Financial Sector Currently, with the continuous integration and development of China's financial sector, cross-industry transactions are becoming increasingly frequent, leading to growing regulatory challenges. In response to this shift, He Hongqing [12] found that establishing a collaborative regulatory framework for financial market behavior supervision and prudential regulation based on blockchain technology can effectively enhance the efficiency of regulating mixed-operations in the financial sector and promote effective competition in financial markets. According to Hu Qilei [13], in terms of financial regulation, the traceability and information transparency of blockchain technology can promptly capture neglected transaction rules and enterprises that violate transaction credibility, and impose corresponding penalties, thus contributing to the maintenance of corporate financial security. Zhou Qian [14] pointed out that with the advancement of "new infrastructure" in blockchain finance, the methods for regulating mixed operations in the financial industry will progress rapidly with technological advancements, and regulatory information will be shared in real time, overcoming the problem of asymmetric information in traditional financial regulation. Based on the above research, it is evident that in the digital 395 economy era, blockchain, as an important component of "new infrastructure," with its inherent traceability and information transparency, can effectively streamline the number of regulatory agencies, reduce regulatory costs, achieve unified regulation, fill regulatory gaps, and thereby address the longstanding regulatory challenges that have plagued China's financial industry, providing technical support for the stable development of the country's financial sector. 4.3. Contribute to Promoting the High-Quality Development of the Financial Industry With the advancement of China's strategy for high-quality economic development and the deepening of supply-side structural reforms year by year, the financial sector, as an important component of the modern economic system, plays a crucial role in resource allocation and its development efficiency directly relates to the high-quality development of today's socio-economic landscape. The high-quality development of the financial sector serves as an important pathway and strong support for the high-quality development of the economy. Technologies such as smart contracts and consensus mechanisms within blockchain technology can simplify transaction processes, reduce financial risks, and drive the high-quality development of the financial industry. On one hand, smart contracts can streamline financial transaction processes, thereby providing more efficient and standardized financial services. Currently, manual processing of financial transaction information still dominates the financial sector, adversely affecting the timeliness and efficiency of financial information transmission. The use of smart contracts and asymmetric encryption technology in blockchain digitizes market transactions, automates contract execution, and enhances transaction transparency, effectively reducing transaction costs, improving transaction efficiency, and propelling the high-quality development of the financial industry. On the other hand, blockchain technology provides strong technical support for reducing financial risks. The distributed ledger and consensus mechanism of blockchain can enhance the transparency of transaction information, ensuring the security and reliability of transaction data, thereby effectively reducing financial risks. Research by Li Ruixue [15] has found that smart contracts, leveraging the core advantages of decentralized blockchain and the real-time visibility of transaction data, ensure decision consistency, achieve credit data transparency, and demonstrate positive effects in financial transaction security, financial democracy, and financial transparency. Analysis reveals that smart contracts, by transforming trust mechanisms and accelerating the flow of credit value, tightly integrate blockchain technology into financial scenarios. Smart contracts and asymmetric encryption technology can reduce the costs and time associated with financial transactions, enhancing the operational efficiency of the financial industry. The consensus mechanism and distributed ledger system provide robust technical support for reducing financial risks and driving the high-quality development of the financial industry. 5. Conclusion The application of blockchain technology and smart contracts brings significant changes and opportunities to the financial industry." They bring many advantages to the financial industry by improving transparency, reducing transaction costs, and enhancing security. From the application examples in various financial fields such as cross- border payments, supply chain finance, equity financing and securities issuance, and the insurance industry, the application of blockchain technology and smart contracts is gradually changing the pattern of the financial industry, providing more possibilities for financial services.
