1/
With Event-Sourcing, your source-of-truth is an append-only series of events.
Ex: USER_REGISTERED, EMAIL_ADDRESS_VERIFIED, PASSWORD_CHANGED, etc.
In ActivityPub, this is similar to the inbox, outbox, etc being an append-only series of Activity.
Ex: Create, Like, Undo, etc.

With Event-Sourcing, you can "project" the events to get another (often more peformant) view of the data in the events.
Without having to incur the cost of having to read all the events to figure out the final state.

With ActivityPub, Activities are often applied to an object. That object gets assigned an ID in the form of a URL.
(And, by URL I mean URL, URI, IRI, etc.)
One doesn't have to read through all the Activities in an inbox, outbox, etc to get the final state of an object.
One can just get the JSON-LD document from the object's ID URL to get the final state.
