The main advantage of using a decentralized application (dApp) is its ability to operate without a central authority, enhancing security and transparency through blockchain technology. This approach minimizes risks associated with data breaches and improves user control over personal information, as clients can interact directly with the application's functionalities. Furthermore, dApps promote greater resilience and can be more resistant to censorship, providing an equal opportunity for all users to participate. In summary, dApps offer enhanced trust and independence compared to traditional centralized applications.
