They aren't cucumbers but over here in Europe, eggs do have a serial number.
Making an analog asset machine readable and tied to a trackable digital asset is certainly an entertaining thought.
Especially for an industry like the food industry where currently we have to trust that the state is controlling them correctly or even that they are controlling them themselves (which several food scandals showed that this isn't working very well).
But we're still early days in that regard. None of the existing crypto coins could handle the necessary transaction volume.
- nsomaru 8y agodo you have a counter argument for: "you still need to trust the devices that write to the blockchain" -- so ultimately you would be trusting the supplier.

- hanniabu 8y agoIn order to write to chain you need a key. If malicious activity is found, these keys can be banned from the network along with any products that they verify. It's not that the system can't be exploited, it's introducing incentives to make it economically unviable to do so.

The supply records a record, immutable(like a git commit log), and posts the resulting hash every hour-is to the public chain. The information recorded remains confidential, but the posted public hash can be used to prove during an audit that the log didn't change. The confidential log can have extremely high transaction volumes, because its internal.
