How Does Telegram Work?
The core concept behind Telegram Messenger revolves around peer-to-peer technology. Each user has a unique identifier, and all conversations occur directly between these peers. This eliminates the need for servers to manage communication, making it faster and more efficient.
Messages are sent and received over the network using UDP packets. Once a message reaches its destination, it is decrypted at the receiving end before being displayed to the user. To ensure data integrity, Telegram uses digital signatures and hash functions.
For voice and video calls, Telegram relies on peer-to-peer connections but incorporates features like local storage, caching, and CDN acceleration to improve performance and reliability.
In summary, Telegram operates primarily based on peer-to-peer communication, leveraging UDP for fast transmission and ensuring data security through cryptographic methods.
