TelegramAndroid VS ContactDiscoveryService

This issue on github explains better what is going on: https://github.com/forkgram/TelegramAndroid/issues/150

Forkgram (version 9.5.8.0): Forkgram is a fork of the official Telegram for Android application.

Best foss YT client no doubt, it plays every yt video with rare crashes, Libretube is best UI wise and have MU but it can't play every yt video, so it this app in MU will be bliss :) * Tasks.org apparently dev of this app tried to implement MU but i think he said, due to code languge it is not possible * Aegis/Authenticator Pro Both are best 2fa apps there is no doubt but i prefer Authenticator pro for it's more features and seamless backup...Dev. of aegis denied MU in issues page of his repo, Maybe Auth. Pro will have it :) There is Mauth with MU but still in Alpha so it's unusable * Bitwarden It is always a nice thing to see this app in MU :) best password manager (I know for 2fa app and password managers we don't supposed to look of UI but still) * Forkgram Besically all telegram clients lacks MU, there is workaround with TG monet (which i use) but you have to manually apply theme everytime so inbuilt monet will be great. Nonfoss apps like MDgram have monet theme (but this is foss sub) * VLC Just imagine how nice it would look if most widely used media player follows MU :), let's hope it will get it soon :)

Forkgram have that feature to nuke messages.

Signal uses SGX for remote attestation, which presumably lets the client verify that the code running on the server is a build of the OSS code and not a modified version. But I don't know the details or if this is reliable.

SGX and remote attestation described here:

Signal does private contact discovery and the effort they've gone to to do this is quite impressive.

TEEs have numerous privacy-enhancing applications that may benefit users. One of them is, as discussed earlier, private contact discovery; the Signal application uses a contact discovery service enhanced using Intel SGX, a TEE technology, to protect its users' privacy. A similar application of TEEs is performing malware analysis in a remote cloud service, so that the service may not identify users by the contents of their devices, such as the applications they have installed, especially important as 98.93% of users may be uniquely identified by the list of applications they have installed.

Signal (or, more accurately, one of its predecessors) used to use client-side private set intersection for contact discovery, but this scales poorly [1].

Now they use a solution based on Intel SGX and server-side trusted computing [2].
