Channels will be public and likely for all users to join, so messages in them may not be end-to-end encryption as is always the case in the app.
Only channel owners will have the ability to send messages within channels, while other members will only receive messages, and may give them some options to interact with messages.
WhatsApp will also allow channels to be searched for and accessed through their unique identifier.
This feature is very similar to the channels feature in the competing instant messaging application “Telegram”, which has been in it since 2015, and it seems that the parent company Meta of WhatsApp will transfer the channels feature in terms of name and work mechanism as it is from “Telegram”.--
Updates from channels may be displayed alongside statuses on the same tab, and may be moved to be present in the message box alongside other conversations.
Telegram channels differ from groups, as groups allow the exchange of messages between members within the group, and there is a ceiling for members within one group that does not exceed 1024 members in the group.
Currently, the channel feature in WhatsApp is under trial, and will be released later to the public after the completion of the beta phase. (Arabic)
