you sure can get reasonable close with 2 phase commit, and starting with next release and quorum commit you will be able to do exactly that.

Quorum commit is not the same as distributed strict serialization because replicas can desynchronize.

Additionally you have the bottleneck of a single master. Will it be possible to do a quorum read as well, and will every transaction on the master be doing it? Then you are starting to get closer, although many anomalies are still possible.
