Añadir un tag ["-"] indica a los relays que solo el autor puede publicar este evento, para que otros no lo copien a relays donde no debía estar.
Edita el formulario o el JSON: ambos se mantienen sincronizados, la insignia indica si el resultado es válido y, al tocar cualquier campo, se explica qué hace.

| 1 | Cliente de Dave | Relay Delta | Dave publica una nota protegida antes de autenticarse. |
| 2 | Relay Delta | Cliente de Dave | El relay pide al cliente que demuestre quién es. |
| 3 | Relay Delta | Cliente de Dave | Hasta que Dave se autentique, el evento protegido se rechaza. |
| 4 | Cliente de Dave | Relay Delta | Dave firma el desafío (NIP-42), demostrando que controla su pubkey. |
| 5 | Cliente de Dave | Relay Delta | Dave reenvía el mismo evento. |
| 6 | Relay Delta | Cliente de Dave | La pubkey autenticada coincide con el autor del evento, así que se almacena. |
| 7 | Cliente de otra persona | Relay Delta | Otra persona intenta publicar la nota firmada de Dave. |
| 8 | Relay Delta | Cliente de otra persona | Su conexión no está autenticada como Dave, así que el relay la rechaza. |

Los relays comprueban la autoría con AUTH de NIP-42.
Los grupos basados en relays suelen proteger así sus eventos.
Los reposts de eventos protegidos no deben incrustar el original.

When the "-" tag is present, that means the event is "protected".
A protected event is an event that can only be published to relays by its author. This is achieved by relays ensuring that the author is authenticated before publishing their own events or by just rejecting events with ["-"] outright.
The default behavior of a relay MUST be to reject any event that contains ["-"].
Relays that want to accept such events MUST first require that the client perform the NIP-42 AUTH flow and then check if the authenticated client has the same pubkey as the event being published and only accept the event in that case.
Reposts of protected events MUST NOT embed the reposted event. If a repost of a protected event embeds the event anyway, relays SHOULD summarily reject it.
The tag is a simple tag with a single item: ["-"]. It may be added to any event.

There are multiple circumstances in which it would be beneficial to prevent the unlimited spreading of an event through all relays imaginable and restrict some to only a certain demographic or to a semi-closed community relay. Even when the information is public it may make sense to keep it compartimentalized across different relays.
It's also possible to create closed access feeds with this when the publisher has some relationship with the relay and trusts the relay to not release their published events to anyone.
Even though it's ultimately impossible to restrict the spread of information on the internet (for example, one of the members of the closed group may want to take an event intended to be restricted and republish it to other relays), most relays would be happy to not facilitate the acts of these so-called "pirates", in respect to the original decision of the author and therefore gladly reject these republish acts if given the means to.
This NIP gives these authors and relays the means to clearly signal when a given event is not intended to be republished by third parties.
