Tencent Applies for Blockchain Data Cleaning Patent to Enhance Performance and Security

On January 30, 2025, the State Intellectual Property Office of China revealed that Tencent Technology (Shenzhen) Co., Ltd. had applied for a patent titled "Blockchain Data Cleaning Method, Device, Computer Equipment, and Storage Medium," with publication number CN119377196A and an application date of July 2023. This patent application aims to address data redundancy and the accumulation of outdated data in blockchain systems, thereby improving blockchain performance and efficiency while ensuring security.

The patent abstract details the core method, which comprises the following steps: first, the system identifies expired transaction tasks within its maintained transaction cleaning tree; second, it retrieves a preset number of target transaction tasks from the transaction pool; third, it generates a new block proposal message based on the expired and target transaction tasks, including the identification information of the expired tasks; finally, it broadcasts the proposal message to the first node in the blockchain, which uses the target transaction tasks to reach consensus on the new block. Upon reaching consensus, the system cleans up the expired data based on the identification information.

A key advantage of this technology lies in its integration of data cleaning with the blockchain's consensus mechanism. By performing data cleaning concurrently with consensus, the method avoids separate cleaning steps, reducing system overhead and improving efficiency. Furthermore, as data cleaning is constrained by the consensus mechanism, the security of the process is ensured, preventing malicious nodes from tampering with or deleting crucial data. This approach effectively balances performance and security, mitigating the security risks or performance bottlenecks potentially present in traditional methods.

The patent application covers "blockchain data cleaning methods, devices, computer equipment, storage media, and computer program products," indicating a comprehensive solution from methodology to implementation. This highlights Tencent's investment and capabilities in blockchain technology R&D and suggests broad application prospects.

The patent mentions smart transportation as a potential application scenario; however, the technology's applicability extends to any field requiring the processing of large transaction volumes and data integrity and security. For example, in finance, it can clean up expired transaction records to improve efficiency; in supply chain management, it can track and manage goods flow, increasing transparency and efficiency; and in healthcare, it can securely store and manage patient medical data, protecting privacy and security.

This technology is significant for blockchain development. Blockchain systems have long faced data bloat and performance degradation. As blockchain applications proliferate, data volume will continue to grow, posing greater challenges to system performance. Tencent's patent offers an effective solution, significantly improving performance and scalability.

By cleverly combining data cleaning with the consensus mechanism, the technology enhances both efficiency and security. Traditional data cleaning methods often require extra steps and resources, making them vulnerable to attacks. Tencent's approach integrates data cleaning into the consensus process, making it more secure and reliable. This is crucial for promoting blockchain adoption, boosting confidence among businesses and users.

Furthermore, the successful patent application reflects Tencent's proactive approach to technological innovation and ongoing investment. As an internet giant with extensive experience, Tencent's exploration and practice in blockchain technology contribute to its advancement. This patent technology is expected to provide strong technical support for the wider adoption of blockchain across various sectors.
