China Mobile Applies for Patent on Blockchain-Based Data Query Method to Enhance On-Chain Query Efficiency

China Mobile Communications Group Design Institute Co., Ltd. and China Mobile Communications Group Co., Ltd. jointly filed a patent titled "Blockchain-based data query method, device and storage medium," with publication number CN118796886A, on December 2023. The patent aims to optimize blockchain data query processes and improve query efficiency by introducing skip list information.

The patent abstract indicates that the core of this method lies in utilizing skip list information to achieve efficient data querying. Specifically, the method involves the following steps:

1. Obtain Search Conditions: Users input search conditions, such as the data type or keywords they need to query.

2. Generate Search Vector: The system generates a corresponding search vector based on the search conditions, used to match blockchain data.

3. Obtain Skip List Information: The system retrieves the first skip list information from the last block in the blockchain and uses it as the initial search skip list information.

4. Determine Target Block: Based on the matching results of the search skip list information and the search vector, the system identifies the block containing the target data.

5. Retrieve Target Block: The system retrieves the target block to confirm the target data.

6. Data Quantity Determination: The system determines whether the amount of target data is sufficient. If insufficient and the target block is not the genesis block, the system obtains the second skip list information corresponding to the target block as the new search skip list information and repeats steps 4-6 until the target data quantity is sufficient or the target block is the genesis block.

By using skip list information, this method can effectively reduce unnecessary retrieval, avoid traversing all blocks, and significantly improve query efficiency.

The skip list information mentioned in the patent is one of the key technologies. A skip list is a data structure that helps to quickly locate the position of data. Compared to traditional linear linked lists or tree structures, skip lists have higher retrieval efficiency. Applying skip list information in blockchain can effectively reduce the number of data traversals during the query process, saving time and resources.

Furthermore, this method offers the following advantages:

• Enhance On-Chain Query Efficiency: Compared to traditional linear query methods, this method can effectively shorten query time and improve user experience.

• Reduce Resource Consumption: By reducing the number of data traversals, this method can lower resource consumption during the query process, enhancing system performance.

• Enhance Data Security: This method is based on blockchain technology, ensuring a high level of security and effectively preventing data tampering.

In conclusion, the patent filed by China Mobile aims to optimize blockchain data query processes and improve query efficiency by introducing skip list information, providing a more efficient and convenient data query solution for practical blockchain applications. The application of this technology will further drive the development and application of blockchain technology, laying the foundation for building a more efficient, secure, and transparent data management system.

It is worth noting that this patent is just one of China Mobile's many innovative achievements in the blockchain field. In recent years, China Mobile has actively invested in blockchain technology research and has explored applications in various fields, including data security, supply chain management, digital asset management, and more. In the future, China Mobile will continue to delve deeper into blockchain technology, continuously developing and applying new technological achievements to contribute to the advancement of the digital economy and social progress.
