Are you planning to give ZeroBazaar a try when the project is complete?
Once this integration is completed, the difference between ZeroBazaar and OpenBazaar could not be clearer. Network stability, anonymity through Tor hidden services, removing the single store of failure, and running offline will all be made possible in ZeroBazaar. At this time, OpenBazaar does not support any of these features natively, although they may be added in a future client release.
