NIP-15

End of Stored Events Notice

final optional author:Semisol

Relays may support notifying clients when all stored events have been sent.

If a relay supports this NIP, the relay SHOULD send the client a EOSE message in the format ["EOSE", <subscription_id>] after it has sent all the events it has persisted and it indicates all the events that come after this message are newly published.

Client Behavior

Clients SHOULD use the supported_nips field to learn if a relay supports end of stored events notices.

Motivation

The motivation for this proposal is to reduce uncertainty when all events have been sent by a relay to make client code possibly less complex.
