Abstract: The emergence of blockchain technology has spurred innovation in various domains, including decentralized communication systems. In this context, a decentralized chat application leveraging blockchain, Remix Ethereum IDE, Ganache blockchain, and MetaMask offers a novel approach to secure and privacy-centric messaging. The application harnesses blockchain's immutable ledger to store chat messages, ensuring data integrity and censorship resistance. Remix Ethereum IDE provides developers with a robust environment for crafting smart contracts, the backbone of the chat application's functionality. Developers can design and deploy smart contracts defining chatroom logic, message encryption, and user authentication. Ganache blockchain serves as a local testing environment, enabling developers to validate smart contracts and simulate blockchain interactions in a controlled setting. This facilitates rapid iteration and debugging during the development phase. MetaMask acts as the gateway for users to access the decentralized chat application. Through MetaMask, users authenticate securely using their Ethereum wallets, ensuring pseudonymous identity verification and enabling seamless interaction with the Ethereum blockchain. Together, these technologies form the foundation of a decentralized chat application that prioritizes privacy, security, and user control. By leveraging blockchain and associated tools, the application offers a compelling alternative to centralized messaging platforms, empowering users with sovereignty over their data and communication.
