What is Telegram?

Telegram is a cloud-based mobile and desktop messaging service that was developed in 2013 by brothers Pavel and Nikolai Durov, who also founded the Russian social network VK. Telegram claims to have over 500 million active users as of January 2023. Telegram’s major purpose is to create a fast, secure, and simple means for people to connect with each other.

Telegram is built on the MTProto protocol, which uses end-to-end encryption for secret talks and client-server encryption for cloud chats. This implies that only the sender and the receiver may read the messages in secret chats, whereas the texts in cloud chats are saved on Telegram’s servers and can be accessed from any device. Telegram also allows users to establish self-destruct timers for their conversations, delete communications for both parties, and make secret chat invitations that expire after a specific period.

Telegram is not only a messaging software, but also a platform for generating and sharing all forms of content. Users can build channels to broadcast messages to infinite subscribers, groups to chat with up to 200,000 members, bots to automate jobs and provide services, stickers to express emotions, and themes to personalize the app’s design. Users can also share and receive any form of media items, such as images, movies, audio, documents, contacts, places, etc., without any limit on their size or quality.

How does Telegram work?

Telegram operates by employing a distributed network of servers around the world to send messages faster and more consistently than other apps. Telegram also uses powerful encryption techniques to safeguard the security and privacy of its users’ data. Here is how Telegram works in greater detail:

  • When a user sends a message to another user or a group chat, the message is encrypted with a unique key and transferred to the nearest server.
  • The server then transfers the message to the recipient’s device or devices (if they have more than one) or to other servers if they are closer to the recipient.
  • The recipient’s device decrypts the message with the same key and shows it on the screen.
  • If the message is sent in a secret chat, the key is produced on the devices of both parties and never kept on the servers. If the message is sent in a cloud chat, the key is created by the server and saved in an encrypted form.
  • If the communication has a self-destruct timer or is destroyed by either participant, it is erased from both devices and from the server.
  • If the message is sent in a channel or a group chat with more than 200 people, it is encrypted with an additional layer of encryption called server-client encryption. This means that only the server can decode the message and send it to the subscribers or members.

What are the main features of Telegram?

Telegram includes several features that make it a flexible and effective chat service. Some of these characteristics are:

Secret Chats

Secret chats are one-on-one communications that employ end-to-end encryption and self-destruct timers. Secret conversations are not kept on Telegram’s servers and may only be viewed from the devices that created them. Secret chats also contain extra security features such as screenshot protection, message deletion for both participants, and secret chat invites that expire after a specified period.

Cloud Chats

Cloud chats are discussions that employ client-server encryption and are saved on Telegram’s servers. Cloud conversations may be accessible from any device that has Telegram installed and signed in with the same user. Cloud chats also provide certain benefits over hidden conversations such as limitless message history, media sharing without compression or size restriction, offline access, multi-device support, etc.

Voice Calls

Voice calls are encrypted voice interactions that employ peer-to-peer connections wherever feasible. Voice calls also employ artificial intelligence to minimize data use and increase sound quality. Voice calls may be initiated from any conversation simply touching on the phone symbol.

Video Calls

Video calls are encrypted video interactions that employ peer-to-peer connections wherever available. Video calls also employ artificial intelligence to minimize bandwidth use and increase video quality. Video calls may be started from any conversation by touching on the camera icon.

Group Chats

Group chats are discussions that may have up to 200,000 people. Group chats may be public or private, and can include moderators that can control the group’s settings, members, and messages. Group chats may also contain voice conversations, which are live audio broadcasts that can have limitless participants.

Channels

Channels are broadcast platforms that might have limitless subscribers. Channels may be public or private, and can have administrators who can submit messages, modify messages, remove messages, pin messages, etc. Channels may also feature voice conversations, which are live audio streaming that can have limitless participants.

Bots

Bots are accounts that are run by software and offer different services and tasks. Bots may be added to any conversation by inserting their username with the @ symbol. Bots may also be developed by anybody using Telegram’s Bot API.

Stickers

Stickers are expressive graphics that may be transmitted in any communication. Stickers are arranged in sets that may be made by anybody using Telegram’s Sticker API. Stickers may also be animated and have sound effects.

Themes

Themes are changes that affect the look of the app. Themes may be produced by anybody using Telegram’s Theme Editor. Themes may also be shared and applied by other users.
