WebRTC, or Web Real-Time Communication, is primarily used for enabling real-time audio, video, and data sharing directly between web browsers. In the context of cryptocurrencies, it facilitates peer-to-peer communication without the need for an intermediary server.When applied to decentralized applications (dApps), WebRTC allows users to communicate effectively while maintaining privacy and security. This is particularly useful for platforms that involve trading, collaboration, or sharing information, as it enhances the user experience by enabling instant interactions.Additionally, WebRTC can be utilized in smart contracts and decentralized exchanges. By integrating real-time communication features, users can verify transactions, share vital data, and negotiate terms on the fly. This reduces latency and streamlines processes, making interactions more efficient.Overall, WebRTC provides a robust solution for enhancing communication in various applications, contributing to trust and transparency within decentralized networks. Its use in cryptocurrency projects highlights the growing importance of connecting users directly and fostering collaborative environments.
