 An Open edX Event is compatible with the event bus when its payload can be serialized, sent, and deserialized by other services. The payload, structured as `attrs data classes`_, must align with the event bus schema format which in this case is the :term:`Avro Schema`. This schema is used to serialize and deserialize the :term:`Event Payload` when sending it across services.
 
-This ensures the event can be sent by the producer and be then re-emitted by the same instance of `OpenEdxPublicSignal`_ on the consumer side.
