I know work is ongoing in the CRDT space (Kleppman's work gets posted here regularly). I'm assuming Hellerstein et al. are continuing work on distributed consistency, but "what and where" is not immediately obvious . Bloom/bud is being maintained, but that seems to be about it.

It seems like event-sourcing draws a tiny bit from this well, but it could be much more powerful with some help from CALM or similar.

Can anyone point to any other areas of active research and development in the area of reducing conflict in distributed systems?
