Fred Smith, chairman and chief executive of the U.S. logistic giant FedEx, yesterday said: "Blockchain has the potential to completely revolutionize what's across the border."

Logistics is thought to be one of the industries that blockchain tech could be most effective in, with increased efficiency and transparency improving the system from warehousing, to delivery, to payment.

Smith has previously signalled his interest in blockchain, with FedEx joining the Blockchain in Transport Alliance (BiTA) earlier this year.
