Working professionally with VMI / 3rd party inventories, I don't see how Blockchain would solve anything that isn't solved already. Maybe a well implemented blockchain solution is solving it easier, that's it so.
The main problem with third party inventories is always the question is the reported inventory levels and movements are actually correct. The real world answer to that is counting, together with the third party if so desired. Blockchain doesn't help with that since in itself it cannot guarantee that the physical movements and the dogital information flow are always in sync.
