Use Case
As every Thursday, you order 42 raw eggs online. You want them to be delivered safely and unbroken, so you have to trust the delivery company that they handle your package with care. The egg shop might apply stickers to the packaging, but in the end the delivery itself is "blind" for the receiver (you) and the sender (the egg shop). If the package gets damaged on the way, it is very difficult to find out later when and where the damage happened -- in some cases this might turn into an insurance issue.
... but what if the package itself could tell you a story about how it has been handled and in case of damage could tell you when and where it happened -- everything ensured by the immutability and trustworthiness of a public distributed ledger? Introducing "Argos Delivery" - an IOTA Streams demo application.
