Telegram apps areopen sourceand supportreproducible builds.Anyone can independently verify that Telegram apps you download from App Store or Google Play were built using theexact same codethat we publish.
For the moment we are focusing on open sourcing the things that allow developers to quickly build something using our API. We have published the code for our Android, iOS, web and desktop apps (Win, macOS and Linux) as well as the Telegram Database Library.
This code allows security researchers tofully evaluateourend-to-end encryption implementation.It is also possible toindependently verifythat Telegram apps available on Google Play and App Store are built using thesame codethat we publish on GitHub.
