How Keychat thinks about group The essence of a group is to establish a boundary where only members can participate in communication. In a decentralized system, this boundary can only be enforced through encryption. Groups generally fall into two categories: **chat groups** and **feed groups**. The former focuses on interaction—members are visible to each other, and messages are shared with the entire group. The latter is centered around content sharing—members are invisible to one another, and messages are individually encrypted for each recipient rather than broadcast to all. Compared to chat groups, feed groups create much less social pressure, allowing both the sharer and the recipients to interact in a more relaxed and private environment. View quoted note →
