That would let you describe the current location of each container, right? Presumably we also want to describe a history of locations and events for each container so we're talking a few additional orders of magnitude more storage and complexity. But still, your point 100% stands. We're not talking about something that traditional technologies can't handle. Although to be fair it seems like the blockchain fans are trumpeting the "publicly available ledger" aspect and not the "suitability for Big Data" angle... I'm no blockchain booster, but I don't think anybody is claiming that it outperforms a trad DB.
