	// More emitters must submit the same execution to reach consensus.
	Status_Proposed Status = 1
	// InProgress informs that the execution reach consensus and the processing of execution must start.
	Status_InProgress Status = 2
	// Completed is a success status after execution was processed and result submitted.
	Status_Completed Status = 3
	// Failed is an error status after execution was processed but an error occured.
	Status_Failed Status = 4
