Event sourcing as an implementation strategy for the persistence of state, e.g. of aggregates. This strategy should not be exposed beyond the boundaries of aggregates. The events from event sourcing should therefore only be used internally in the corresponding aggregate or in the context of CQRS to build related read models.

Domain events, on the other hand, represent a specific fact or happening that is relevant regardless of the type of persistence strategy for aggregates, for example, for integrating bounded contexts.

Event sourcing and domain events can of course be used both at the same time, but should not influence each other. The two concepts are used for different purposes and should therefore not be mixed.
