WeBank Files Patent for Secure Communication Between DApps and Digital Wallets, Enhancing Decentralized Application Interaction Security

On January 25, 2025, the State Intellectual Property Office of China published information showing that WeBank (Shenzhen Qianhai WeBank Co., Ltd.) filed a patent application for a "Communication Method and Device Between Decentralized Application (DAPP) and Digital Wallet," with publication number CN119341828A and an application date of October 2024. This patent aims to solve the problem of secure communication between decentralized applications (DApps) and digital wallets by enabling direct and secure interaction without relying on any third-party services.

The patent abstract details the technology's mechanism. The method involves the following steps: First, the DApp publishes a first message to a specific topic (first topic) monitored by the blockchain system. This message contains information indicating a first generation element (first instruction information). Then, the DApp retrieves a second message from the first topic, published by the digital wallet. This second message contains information indicating a second generation element (second instruction information). The digital wallet uses the first generation element obtained by decrypting the first message to generate another specific topic (second topic) monitored by the blockchain system. The DApp then uses the second generation element obtained by decrypting the second message to identify this second topic. Finally, the DApp communicates with the digital wallet through this second topic.

The key to this technology lies in its ingenious use of blockchain characteristics. By publishing and receiving information on the blockchain, a secure and reliable communication channel is established between the DApp and the digital wallet. Traditional DApp and digital wallet communication often relies on third-party service providers, increasing communication costs and security risks. Third-party providers may be vulnerable to attacks, leading to data breaches or transaction tampering. WeBank's patented technology effectively mitigates these risks. By decentralizing the communication process and placing it entirely under blockchain supervision, the security and reliability of communication are enhanced. This direct, peer-to-peer communication model not only improves efficiency but also strengthens user privacy protection.

This patent application offers a more secure, efficient, and reliable solution for DApp and digital wallet interaction. In the context of the booming decentralized application market, securing communication between DApps and digital wallets is crucial. WeBank's patented technology provides a novel approach to addressing this issue. It will contribute to the healthy development of the decentralized application ecosystem and promote a thriving digital economy.
