Multi-writer will allow Dats to be modified by multiple devices and multiple authors at the same time. Each author will have their own secret key and publish a Dat with their data in it. Multi-writer fuses all of these separate Dats into one “meta-Dat” that is a view of everyone’s data combined

Partially ordered event-based systems are well placed to supportsuch branching-and-merging workflows, since they already makedata changes explicit in the form of events, and their support forconcurrent updates allows several versions of a dataset to coexistside-by-side.

in Git terms, one user can create a branch (a setof commits that are not yet part of the main document version),and another user can choose whether to merge it
