Abstract
A stunning technological upgrading of the Internet and its uses for companies, individuals, and public organizations is promised by the Blockchain. It allows to realize peer-to-peer transactions, and also to incorporate legally binding "smart contracts" with no need for central authorities or third parties other than the Blockchain itself. There is yet another concept that promises to revolutionize the way we trade, the Physical Internet. Like the Blockchain, it is expected have the capability to be permissioned or permissionless (e.g. known traders or anonymous auctioneers), and and to be distributed. By the year 2050, because of its high degree of standardization and automation, a trader expecting a good to move from and to any place at a specified time, will no longer have to worry for the cheapest or most sustainable solutions, because it all will be optimized by the Physical Internet itself. This document lays out a first Blockchain use case for the Physical Internet. We first outline the Blockchain and Physical Internet concepts, the use case developed with Hyperledger Fabric, and the future capability requirements for the future development of the Physical Blockchain use case.
