Keychat's initial encrypted group chat implementation, known as "pairwise group," will be rebranded as "small group" in the forthcoming version.
In this setup, when a group member sends a message within the small group, they are effectively sending a separate one-on-one message to each other member, creating a group chat through multiple individual chats. Thus, this model nearly completely retains the security features of one-on-one chats, fulfilling the five previously mentioned requirements.
However, it supports only a limited number of participants and operates on an expensive "one stamp per message" basis.
