To further improve transparency on Telegram, official third-party services are able to assign extra verification icons to user accounts and chats — in order to prevent scams and reduce misinformation.
This is done through official verified bots, verified by Telegram as specified here ».
Once verified by Telegram, the following schema can be used by the bot or by the user that owns the bot to assign or revoke the third-party verification icon of user accounts and chats:

Bots that have the verifier_settings flag set may invoke bots.setCustomVerification to verify or unverify peers: this method may be also invoked by the owner of the verifier bot, passing the bot's ID in bot.
Verified peers will have the bot_verification_icon flag populated with the ID of the custom emoji » used as verification icon in the associated user, channel constructors, and a more detailed bot_verification flag containing a botVerification constructor in the associated userFull, channelFull, chatInvite constructors.
