In these kinds of cases it's mostly about simplifying transactions or contracts via hash-based signatures. Scenario: 1. You request service A from me 2. I confirm receipt of service request 3. I provide service A 4. You confirm receipt of service A and provide payment 5. I confirm receipt of payment Since each block of a blockchain is dependent on the previous blocks, it makes it impossible for me to go back and adjust the record to say, claim you never paid me, or change the order quantity, or for you to go back and claim you never ordered a thing. It makes 5 depend on 4 which depends on 3 which depends on 2 which depends on 1 and altering any of the steps "breaks" the later steps in such a way that you not only can tell they're broken, but also at which step did the chain break. In this sense you can basically use math to provide enforcement of the kinds of transactions that might occur during a sale. With shipping containers you can simply put in movements of the container, or manifest of the containers or track bill of lading [1]. 1 - https://en.wikipedia.org/wiki/Bill_of_lading https://en.wikipedia.org/wiki/Bill_of_lading
