Blockchain is rapidly evolving from a niche technological concept into a foundational driver of global innovation. During the 18th collective study session of the Political Bureau of the CPC Central Committee, President Xi Jinping emphasized the importance of actively promoting the integration of blockchain technology with economic and social development. He highlighted that China possesses a solid foundation in this field and should accelerate the advancement of blockchain technology and industry.
Globally, major economies are intensifying their efforts to develop and implement blockchain solutions. Applications of this technology now extend into digital finance, the Internet of Things (IoT), intelligent manufacturing, supply chain management, digital asset transactions, and numerous other sectors. Promoting its integration is not only beneficial for expanding the applicability and future potential of blockchain but also positions countries to gain a competitive edge in the global technology race and foster high-quality economic development.
Current State of Blockchain Technology
A New Frontier in Global Technology Competition
Blockchain is a decentralized, distributed database system participated in by multiple nodes. It is not a specific product but rather a mechanism—a technical solution—for public bookkeeping. The core idea is to create a shared digital ledger on the internet where all users in the network collectively record and verify transactions, ensuring information authenticity and immutability. The term "blockchain" originates from its use of cryptographically linked data blocks. Each block contains all transaction information from a specific period, which is used to verify the validity of the information and generate the next block.
The three defining characteristics of blockchain—complete traceability, decentralization, and trustlessness—make it particularly promising for the financial industry, where it has emerged as a core component of financial technology (Fintech). While blockchain gained widespread attention through its association with cryptocurrencies like Bitcoin, it is crucial to understand that cryptocurrencies are just one of its applications. The essence of blockchain is decentralization, which aligns with the future direction of market evolution.
Today’s internet has effectively decentralized information sharing but has not achieved the same for transactions. People freely share personal updates, knowledge, and files online but remain hesitant to transact directly with strangers. Most existing financial systems on the internet rely on central banks or highly credible third-party payment processors—essentially centralized solutions. Establishing a global consensus-based trust system is incredibly challenging due to vast differences in politics, economics, and culture between nations. Blockchain technology aims to solve this by breaking the chains of centralized credit systems and enabling trust and monetary interoperability among nodes worldwide. Consequently, applying blockchain to improve market structures is an inevitable trend.
Developed countries such as the United States, the United Kingdom, and Japan are actively participating in this space. Major financial organizations are establishing large blockchain consortia, striving to solidify their international financial centers by gaining a first-mover advantage in blockchain adoption.
Challenges in Technological Maturity
Despite its revolutionary potential, blockchain technology is not yet mature enough for large-scale commercial application. Current limitations mainly involve hardware and performance issues during implementation:
- Transaction speed: The transaction processing speed of a blockchain is inversely related to the number of node copies. More nodes result in slower speeds. For example, Bitcoin can handle a maximum of only seven transactions per second. Even more advanced solutions like HyperLedger process only 200–300 transactions per second—far fewer than the tens of thousands handled by centralized banking and third-party payment systems.
- Node incentives: Maintaining a stable blockchain network requires a sufficient number of active nodes. Since running a node incurs costs, a reasonable incentive mechanism is essential to encourage participation and ensure transactions are recorded and maintained. Currently, such a structured incentive model is lacking, and node participation relies largely on voluntarism or randomness.
- Data consensus cost: In an open network environment, ensuring the security and reliability of blockchain data requires multiple nodes across the globe to participate in bookkeeping simultaneously. However, this process of achieving data consensus is highly energy-intensive. Bitcoin’s “mining” mechanism, for instance, involves extremely high computational costs, with energy consumption reportedly exceeding that of some countries and incurring annual economic costs in the hundreds of millions of dollars. This makes widespread adoption challenging under the current model.
Application Prospects in the Economy and Society
The potential applications of blockchain are vast. The technology has evolved from its first-generation use in Bitcoin to second-generation implementations in payment清算 (clearing), securities trading, healthcare, logistics, government services, and more.
In China’s current economic environment, where credit costs are relatively high and the social credit system is still developing, blockchain offers a low-cost credit platform. This can significantly reduce overall societal credit costs and promote the growth of a credit-based economy. President Xi Jinping pointed out the need to deepen the integration of blockchain and the real economy and to use the technology to facilitate large-scale interoperability between cities in information, capital, talent, and credit reporting. This would ensure the orderly and efficient flow of production factors across regions.
As a major manufacturing nation, China should focus its blockchain development efforts on innovations within producer services to boost productivity in the real economy. Currently, countries are concentrating their blockchain strategies in several key areas.
Payments and Clearing
In payment and clearing, particularly in cross-border transactions, blockchain offers notable advantages by eliminating the need for intermediary banks and enabling fast, low-cost, peer-to-peer payments. Using a blockchain platform reduces中转 fees, enhances security and transparency, lowers risks, and accelerates clearing speeds, thereby improving capital utilization. In the future, banks could interact directly via blockchain without third-party involvement. According to McKinsey estimates, applying blockchain in B2B cross-border payments and结算 could reduce the cost per transaction from about $26 to $15, with nearly 75% of the savings coming from intermediary bank fees and the rest from compliance, error investigation, and foreign exchange costs.
Securities Trading
The securities market is highly suitable for blockchain applications. Traditional stock trading requires coordination among four central institutions: central clearing agencies, banks, securities companies, and exchanges. This process is inefficient and costly. Blockchain can streamline this into an integrated service. This is especially relevant for private equity trading, which requires a reliable system for recording ownership and facilitating transactions without needing extremely high processing power. Both NASDAQ and the London Stock Exchange are experimenting with blockchain in private markets. NASDAQ launched its blockchain platform, Linq, in October 2015, enabling users to hold digital ownership with transparent, auditable records and greater control over issuance and ownership transfer. Once performance issues are resolved, higher-frequency assets like publicly traded stocks may also migrate to such open platforms.
Healthcare
Blockchain holds great promise for authentication and privacy protection in healthcare. Medical records and other user data are highly sensitive and require robust security. Current centralized information systems are vulnerable to network attacks and large-scale data breaches—even tech companies with mature security have experienced incidents. Blockchain’s highly secure encryption and distributed storage architecture are well-suited to address these challenges. For example, Philips Healthcare and Tierion are collaborating to use blockchain for medical record authentication and privacy protection. Complex, programmable permission settings prevent unauthorized access or tampering. Even if parts of the blockchain are compromised, the overall system remains secure.
Logistics
In logistics, blockchain can record every step of a shipment from sender to recipient. By creating a consensus network, it becomes possible to pinpoint issues in the delivery process and ensure traceability, reducing problems like lost parcels, misdeliveries, or warehouse overloads. It also supports the implementation of real-name systems in logistics. Each courier or delivery point has a private key for signing, and recipients must confirm delivery with theirs, preventing forgery and significantly improving delivery accuracy and efficiency. Customers can verify delivery status on the blockchain, ensuring transparency and trust.

Strengthening Regulation for Secure and Orderly Development
President Xi Jinping stressed the importance of strengthening the guidance and regulation of blockchain technology, exploring the establishment of a security guarantee system adapted to its mechanisms, and promoting its safe and orderly development through law-based governance. Therefore, it is essential to accelerate the formulation of relevant laws and regulations, incorporate blockchain into an appropriate regulatory framework, strictly standardize the issuance of virtual currencies, enhance market supervision in finance and other industries, and prevent systemic risks.
Regulatory bodies need to collaboratively address security issues arising from blockchain technology, strengthen oversight, protect public interests, and ensure social stability. Through coordinated regulation, a balance can be struck between the interests of system participants and broader societal benefits, avoiding rigid management structures that could hinder technological innovation.
Given the global spread of underground virtual currency trading, Chinese authorities should cooperate with international financial institutions to accelerate the development of domestic regulatory guidelines, providing a basis for coordinated international policies. Global coordination in regulation is necessary to combat illegal cryptocurrency transactions and criminal activities effectively. Regulatory tools could include blockchain network risk assessment models to measure virtual currency risks accurately and enhance the enforcement capacity against related crimes.
Since blockchain lacks unified industry standards and technical guidelines, institutions develop various isolated applications based on different protocols and needs. To improve guidance and standardization, China should actively participate in formulating international standards, engage with open-source organizations and community groups aligned with global standards, and strengthen communication between national and international standards. This will enhance China’s influence in the global blockchain standards system.
Continuously monitoring industry trends and focusing on key links inadvantageous industries will help gradually improve the application and standardization of blockchain technology. Fostering domestic talent in blockchain development, organizing international seminars, and encouraging collaboration between government, universities, fintech firms, and internet companies to establish research labs and develop applications are vital steps. Forming a national blockchain technology alliance will accelerate the pace of industry innovation.
