-## Abstract
-
 Service providers want to offer live activities to the Nostr network in such a way that participants can easily logged and queried by clients. This NIP describes a general framework to advertise the involvement of pubkeys in such live activities.

+## Concepts

+### Live Event
 
 A special event with `kind:30311` "Live Event" is defined as a _parameterized replaceable event_ of public `p` tags. Each `p` tag SHOULD have a **displayable** marker name for the current role (e.g. `Host`, `Speaker`, `Participant`) of the user in the event and the relay information MAY be empty. This event will be constantly updated as participants join and leave the activity.

 Event owners can add proof as the 5th term in each `p` tag to clarify the participant's agreement in joining the event. The proof is a signed SHA256 of the complete `a` Tag of the event (`kind:pubkey:dTag`) by each `p`'s private key, encoded in hex.

 This feature is important to avoid malicious event owners adding large account holders to the event, without their knowledge, to lure their followers into the malicious owner's trap.

 Event `kind:1311` is live chat's channel message. Clients MUST include the `a` tag of the activity with a `root` marker. Other Kind-1 tags such as `reply` and `mention` can also be used.
