This does seem like a possible application of blockchain to me. Yes, this could theoretically be accomplished with a database but if chain of custody was written to a blockchain it would be immutable. Tracing food supply I think is important to some people and this would provide a cryptographically secure way to do so.

- solotronics 8y agoThis is short sighted. You would at least be able to see exactly who was involved along the line. It would be public knowledge to find unreliable suppliers that had a higher rate of contamination. Also, it would be really cool to see exactly what farm something came from. It doesn't apply to a bag of cheetos but it definately does for a waygu beef steak.
- heyitsguay 8y agoThat has nothing to do with a blockchain though - the data structure you use has no ties to the physical entities entering data into it. If there's a regulatory body enforcing compliance, why wouldn't that regulatory body just maintain a database to track the supply chain? More energy efficient, and it aligns the data with its oversight. If there's no regulatory body, then you're back to the original problem - nothing about a blockchain prevents dirty Farm A from entering Farm B into the ledger.
