How is WhatsApp, Viber, Telegram written - in detail?
When examining the architectural and developmental aspects of messaging applications such as WhatsApp, Viber, and Telegram, it becomes evident that each platform employs a unique blend of technologies to ensure secure, efficient, and user-friendly communication.
WhatsApp, developed by Facebook, is built using a combination of Erlang and Java for the backend services, while the frontend relies on React Native. The application utilizes the XMPP (Extensible Messaging and Presence Protocol) for its core messaging functionality, which allows for real-time communication and presence information. To ensure end-to-end encryption, WhatsApp employs the Signal protocol, developed by Open Whisper Systems, which safeguards user messages from unauthorized access.
Viber, on the other hand, is written primarily in C++ for its core engine, ensuring high performance and efficiency. The frontend of Viber is designed using Qt framework, which provides a rich set of tools for developing cross-platform applications. For messaging, Viber utilizes a proprietary protocol that ensures secure communication between users. Additionally, Viber employs end-to-end encryption to protect user data and communications.
Telegram, known for its focus on privacy and security, is developed using a combination of C++ and Objective-C. The core libraries are written in C++ to ensure performance, while the platform's frontend is developed using native APIs provided by iOS and Android. Telegram employs a custom protocol called MTProto (Mobile Telegram Protocol) for secure communication between clients and servers. This protocol incorporates advanced encryption techniques to safeguard user data and maintain privacy.
In summary, WhatsApp, Viber, and Telegram are developed using distinct technologies tailored to meet their specific requirements for performance, security, and user experience. Each platform employs a combination of programming languages and protocols to ensure efficient, secure, and seamless communication among users.
