Abstract: Decentralized chat applications using blockchain technology are becoming more prominent due to their ability to enhance security and privacy in online communication. This research paper discusses the design and implementation of such an application, focusing on its decentralized architecture and the use of blockchain for secure messaging. The application ensures that messages are encrypted end-to-end, making them resistant to unauthorized access and censorship. Through an in-depth analysis of the application's performance and security features, this paper underscores the benefits of decentralized chat applications in providing a secure and private communication platform. The results highlight the potential of blockchain technology to transform online communication by ensuring security and privacy.

Keywords: Blockchain, Decentralized, Technology, Application.
