In March 2018, Telegram stated that it had 200 million monthly active users. Messages and media in Telegram are only client-server encrypted and stored on the servers by default. Telegram's security model has received notable criticism by cryptography experts. They criticized the general security model of permanently storing all contacts, messages and media together with their decryption keys on its servers by default and by not enabling for messages by default. Pavel Durov has argued that this is because it helps to avoid third-party unsecure backups, and to allow users to access messages and files from any device. Cryptography experts have furthermore criticized Telegram's use of a custom-designed encryption protocol that has not been proven reliable and secure. Telegram has faced censorship or outright bans in some countries over accusations that the app's services have been used to facilitate illegal activities, such as protests and , as well as declining demands to facilitate government access to user data and communications. Development Telegram was launched in 2013 by the brothers and. Previously the pair founded the social network , they left VK when it was taken over by the. Nikolai Durov created the protocol that is the basis for the messenger, while Pavel provided financial support and infrastructure through his fund with partner joining as a second co-founder. Telegram Messenger states that its end-goal is not to bring profit, but it is not currently structured as a non-profit organization. Telegram is registered as both an English and an American. Pavel Durov has said that the service was headquartered in , , between 2014 and early 2015, but moved to different jurisdictions after failing to obtain residence permits for everyone on the team. Durov left Russia and is said to be moving from country to country with a small group of computer programmers. According to press reports, Telegram had employees in. The Telegram team is currently based in Dubai. In December 2017, Cointelegraph reported that Telegram was planning to launch a platform and native. In January 2018, confirmed the news, referring to multiple sources. To fund the TON launch as well as the ongoing support and development of Telegram Messenger, Telegram launched an ICO. A 23-page white paper and a detailed 132-page technical paper of the project were released sequentially. Pavel Durov formed TON Issuer Inc in February 2018. Company officials have not made any public statements regarding the ICO. As of spring 2018, the only official sources of information are the two that Telegram filed with the. Usage numbers In October 2013, Telegram had 100,000 daily active users. On 24 March 2014, Telegram announced that it had reached 35 million monthly users and 15 million daily active users. In October 2014, South Korean governmental surveillance plans drove many of its citizens to switch to Telegram. In December 2014, Telegram announced that it had 50 million active users, generating 1 billion daily messages, and that it had 1 million new users signing up on its service every week; traffic doubled in five months with 2 billion daily messages. In September 2015, an announcement stated that the app had 60 million active users and delivered 12 billion daily messages. In February 2016, Telegram announced that it had 100 million monthly active users, with 350,000 new users signing up every day, delivering 15 billion messages daily. In December 2017, Telegram reached 180 million monthly active users. In March 2018, Telegram reached 200 million monthly active users. Account Telegram accounts are tied to telephone numbers and are verified by or phone call. Users can add multiple devices to their account and receive messages on each one. Connected devices can be removed individually or all at once. The associated number can be changed at any time and when doing so, the user's contacts will receive the new number automatically. In addition, a user can set up an that allows them to send and receive messages without exposing their phone number. Telegram accounts can be deleted at any time and they are deleted automatically after six months of inactivity by default, which can optionally be changed to 1 month and 12 months. The default method of that Telegram uses for is SMS-based single-factor authentication. All that is needed in order to log into an account and gain access to that user's cloud-based messages is a one-time passcode that is sent via SMS to the user's phone number. These login SMS messages are known to have been intercepted in Iran, Russia and Germany, possibly in coordination with phone companies. Cloud-based messages Telegram's default messages are cloud-based and can be accessed on any of the user's connected devices. Users can share photos, videos, audio messages and other files up to 1. Users can send messages to other users individually or to groups of up to 100,000 members. Sent messages can be edited and deleted on both sides within 48 hours after they have been sent. This gives user an ability to correct typos and retract messages that were sent by mistake. The transmission of messages to Telegram Messenger LLP's servers is encrypted with the service's MTProto protocol. This makes the messages' security roughly comparable to that of e-mail. Here, most providers employ client-server encryption as well, however usually with the standardized protocol. E-mails may or may not be encrypted on the servers. Telegram cloud messages and media remain on the servers at least until deleted by all participants. Bots In June 2015, Telegram launched a platform for third-party developers to create. Bots are Telegram accounts operated by programs. They can respond to messages or , can be invited into groups and can be integrated into other programs. It also accepts online payments with credit cards and. Dutch website reported that an invited bot can potentially read all group messages when the bot controller changes the access settings silently at a later point in time. Telegram pointed out that it considered implementing a feature that would announce such a status change within the relevant group. Also there are inline bots, which can be used from any chat screen. In order to activate an inline bot, user needs to type in the message field a bot's username and query. The bot then will offer its content. User can choose from that content and send it within a chat. Channels Channels can be created for broadcasting messages to an unlimited number of subscribers. Channels can be publicly available with an alias and a permanent URL so anyone can join. Users who join a channel can see the entire message history. Each message has its own view counter, showing how many users have seen this message. Users can join and leave channels at any time. Furthermore, users can mute a channel, meaning that the user will still receive messages, but won't be notified. Stickers Stickers are cloud-based, high-definition images intended to provide more expressive. When typing in an emoji, the user is offered to send the respective sticker instead. Telegram comes with one default sticker set, but users can install additional sticker sets provided by third-party contributors. Sticker sets installed from one client become automatically available to all other clients. Sticker images use file format, which is better optimized to be transmitted over internet. Drafts Drafts are unfinished messages synced across user devices. One can start typing a message on one device and continue on another. The draft will persist in editing area on any device until it is sent or removed. Messages can also be sent with client-to-client encryption in so-called secret chats. These messages are encrypted with the service's MTProto protocol. Unlike Telegram's cloud-based messages, messages sent within a secret chat can be accessed only on the device upon which the secret chat was initiated and the device upon which the secret chat was accepted; they cannot be accessed on other devices. Messages sent within secret chats can, in principle, be deleted at any time and can optionally self-destruct. Secret chats have to be initiated and accepted by an invitation, upon which the encryption keys for the session are exchanged. Users in a secret chat can verify that no has occurred by comparing pictures that visualize their. According to Telegram, secret chats have supported since December 2014. Encryption keys are periodically changed after a key has been used more than 100 times or has been in use for more than a week. Old encryption keys are destroyed. Windows and Linux users are still not able to use secret chats using the official Telegram Desktop app while the official macOS-only client supports them. Secret chats are not available for groups or channels. Telegram's local message database is not encrypted by default. Some Telegram clients allow users to encrypt the local message database by setting a passphrase. Voice calls In the end of March 2017, Telegram introduced its own. The calls are built upon the end-to-end encryption of Secret Chats. Connection is established as whenever possible, otherwise the closest server to the client is used. According to Telegram, there is a working to learn various technical parameters about call to provide better quality of the service for future uses. After a brief initial trial in Western Europe, voice calls are now available for use in most countries. Telescope video messages Since version 4. The round videos can be up to one minute long and autoplay. When posted in a public channel on Telegram, the videos are also uploaded to and viewable without an account at. Live locations For either 15 minutes, one hour, or eight hours, Telegram users can share their live location in a chat since version 4. If multiple users share their live location within a group, they are shown on an interactive map. Sharing the 'live location' can be stopped at any time. Social login In February 2018, Telegram launched their feature to its users, named as Telegram Login. It features a website widget that could be embedded into websites, allowing users to sign into a third party website with their Telegram account. The gateway sends users' Telegram name, username, and profile picture to the website owner, while users' phone number remains hidden. The gateway is integrated with a bot, which is linked with the developer's specific website domain. Passport In July 2018, Telegram introduced their and , Telegram Passport, for platforms that requires real-life identification. It asks users to upload their own official documents such as passport, identity card, driver license, etc. When an online service requires such identification documents and verification, it forwards the information to the platform with the user's permission. Telegram stated that it does not have access to the data, while the platform will only share the information to the authorised recipient. However, the service was criticised for being vulnerable to online. A simplified illustration of the MTProto encryption scheme. Telegram uses a scheme called MTProto. The protocol was developed by Nikolai Durov and other developers at Telegram and is based on 256-bit symmetric encryption, 2048-bit encryption and. Servers Telegram Messenger LLP has servers in a number of countries throughout the world to improve the response time of their service. Telegram's server-side software is closed-source and proprietary. Pavel Durov has said that it would require a major architectural redesign of the server-side software to connect independent servers to the Telegram cloud. Client apps Telegram has various client apps, some developed by Telegram Messenger LLP and some by the community. Most of them are and released under the version 2 or 3.

In February 2016, launched an -powered news bot that pushes popular stories to subscribers and replies to search queries with relevant articles. Security Cryptography experts have expressed both doubts and criticisms on Telegram's MTProto encryption scheme, saying that deploying may render the encryption vulnerable to bugs that potentially undermine its security, due to a lack of scrutiny. It has also been suggested that Telegram did not employ developers with sufficient expertise or credibility in this field. Since July 2016, Line has also applied end-to-end encryption to all of its messages by default. On 26 February 2014, the evaluated several data-protection aspects of Telegram, along with other popular instant-messaging clients. Among the aspects considered were: the security of the data transmission, the service's terms of use, the accessibility of the source code and the distribution of the app. Telegram was rated 'critical' kritisch overall. The organization was favorable to Telegram's secure chats and partially open source code, but criticized the mandatory transfer of contact data to Telegram's servers and the lack of an imprint or address on the service's website. It noted that while the message data is encrypted on the device, it could not analyse the transmission due to a lack of source code. Telegram's default chat function received a score of 4 out of 7 points on the scorecard. It received points for having communications encrypted in transit, having its code open to independent review, having the security design properly documented, and having completed a recent independent security audit. Telegram's default chat function missed points because the communications were not encrypted with keys the provider didn't have access to, users could not verify contacts' identities, and past messages were not secure if the encryption keys were stolen. Telegram's optional secret chat function, which provides end-to-end encryption, received a score of 7 out of 7 points on the scorecard. In December 2015, two researchers from published a report in which they demonstrated that MTProto does not achieve IND-CCA or. In April 2016, accounts of several Russian opposition members were hijacked by intercepting the SMS messages used for login authorization. In response, Telegram recommended using the optional two-factor authentication feature. In June 2017, Pavel Durov claimed publicly that U. Cryptography contests Telegram has organized two cryptography contests to challenge its own security. Third parties were asked to break the service's cryptography and disclose the information contained within a secret chat between two computer-controlled users. Both of these contests expired with no winners. Security researcher and commenters on criticized the first contest for being rigged or framed in Telegram's favor and said that Telegram's statements on the value of these contests as proof of the cryptography's quality are misleading. Censorship Blocked partially some ISPs or audio traffic Telegram was open and working in Iran without any VPN or other circumvention methods in May 2015. In August 2015, the asserted that Telegram had agreed to restrict some of its bots and sticker packs in Iran at the request of the Iranian government.
