China Construction Bank (CCB) Applies for Patent on Offline Digital Currency Transactions, Enhancing Hardware Wallet Security and Efficiency

On December 18, 2024, the State Intellectual Property Office of China revealed that China Construction Bank Corporation (CCB) has applied for a patent titled "Offline Transaction Method, Hardware Wallet and Medium for Digital Currency," with publication number CN119130448A and an application date of September 2024. This patent application signifies a significant breakthrough in CCB's digital currency hardware wallet technology, providing crucial technological support for promoting the widespread adoption of digital currencies.

The patent abstract shows that this invention pertains to digital currency transaction technology and discloses an innovative offline transaction method, hardware wallet, and medium for digital currency. Its core lies in improving the design and functionality of hardware wallets to enhance security, efficiency, and practicality. Unlike traditional digital currency hardware wallets, CCB's proposed solution manages and executes transactions for multiple accounts within a single secure module, effectively addressing numerous issues present in existing technologies.

Specifically, the patented method applies to a specialized hardware wallet. This wallet contains multiple processing units and multiple storage units, all located within the same secure module and individually corresponding to multiple different accounts. This design cleverly leverages the isolation of the secure module to ensure that the transaction data of each account is fully protected, preventing financial losses due to security vulnerabilities.

The described offline transaction method is equally innovative. When a business request arrives, such as a transfer transaction, the corresponding processing unit first retrieves the request. Then, based on the request content, the processing unit modifies the information in the storage unit of the corresponding account, such as updating the account balance. This process is completed entirely within the hardware wallet without requiring a network connection, effectively preventing network attacks and data breaches.

Importantly, the patent highlights the advantages of implementing transactions between multiple accounts on the same secure module. This design reduces redundant information generated by managing multiple accounts, thereby improving transaction efficiency and security. It also lowers the hardware wallet's cost, as it eliminates the need for a separate secure module for each account. Reduced cost facilitates wider adoption and accessibility, enabling more users to utilize secure and reliable digital currency hardware wallets.

The core innovation of this patent technology lies in its multi-account management mechanism. Traditional hardware wallets typically support only one account, while CCB's proposed solution supports multiple accounts operating simultaneously within a single secure module. This not only enhances user experience but also provides greater flexibility for various application scenarios. For example, users can allocate different funds for various purposes, such as daily expenses, investments, etc., to different accounts for more refined financial management.

Furthermore, the patent also covers the hardware wallet's medium. While the patent application doesn't detail the specific form of the medium, it can be inferred that this refers to the physical carrier of the hardware wallet, such as a USB storage device or smart card. Selecting an appropriate medium is crucial for ensuring the hardware wallet's security. A secure and reliable medium can effectively prevent the hardware wallet from being tampered with or copied, thus protecting users' digital currency assets.

The significance of CCB's patent application lies in its enhancement of not only the security of digital currency hardware wallets but also their efficiency and practicality. By implementing transactions between multiple accounts on a single secure module, it reduces redundant information, lowers hardware costs, and expands the application scenarios of hardware wallets. This is of significant importance in promoting the widespread adoption of digital currencies.

This technological breakthrough also reflects CCB's commitment and capability for continuous innovation in the digital currency technology field. In today's booming digital economy, secure and reliable digital currency hardware wallets are essential tools for safeguarding digital assets. CCB's patented technology is poised to contribute to the construction of a safer, more efficient, and more convenient digital currency ecosystem.

In summary, the core innovation of China Construction Bank's patent application for "Offline Transaction Method, Hardware Wallet and Medium for Digital Currency" lies in the implementation of a multi-account management mechanism within a single secure module. This not only improves security and efficiency but also reduces costs, representing a significant advancement in digital currency hardware wallet technology. The application of this technology will further promote the popularization and development of digital RMB and contribute to the prosperity of the digital economy. CCB, as a major domestic commercial bank, actively participates in the research and development and application of digital currency technology, demonstrating its emphasis on and investment in fintech, and providing a valuable reference for other financial institutions. The mature application of this patented technology will provide more reliable security and convenience for digital currency users.

In the future, with the continuous improvement and application of this technology, we can expect the emergence of more secure and reliable digital currency hardware wallet products, injecting new vitality into the healthy development of the digital economy. This will not only help improve the market recognition of digital currency but also provide individuals and businesses with more convenient and secure digital asset management solutions. CCB's initiative undoubtedly makes a positive contribution to the development of China's digital currency field.
