Part of Stem. This page defines the group audience.

The audience is every principal that currently holds a live grant on the named group at read or above.

Rules

Group membership is itself expressed by grants whose subject is the group, so one grant from the owner can reach many people and adding or removing a member is one grant or one revocation. Membership is evaluated late: when a member is removed, every node whose readers included the group loses that member at once. Nested groups are allowed in the data model; the first implementation caps evaluation depth and marks deeper nesting an open question.

Today (HM24)

No group concept. The roadmap asks for "one capability granting several keys at once" and a permanode per space; this audience with the Group permanode is that.
