Yeah the integration network between each entity in the supply chain at the moment is complex and highly susceptible to malware attacks. With logistics being such a fluid entity its also hard to build automated systems that can adapt.

In controlled warehouses like Amazon it works like a dream.

Bridging between each company's preferred software application is doable, and it all talks to each other, but yeah I think industry can learn alot from current blockchain applications. ARK for one, and bridging. Getting code to talk to one another is one of the major hurdles right now.

Though I do think block chain and some form of adaptive learning machine intelligence will eventually supersede the systems we have in place right now. I don't think it will be decentralised tech, that is as per IBM no crypto currency tokens governing the staking process and securing the network. But its interesting to watch.
