I am trying to understand how blockchain would be helpful in provenance tracking of goods.
Example: Company X is using blockchain technology to import pork into USA. Let us assume there are many agents in between who transfer porks and finally reaches USA.
My understanding is a every agent who is sending pork would generate a public key + private key combination and add it into blockchain. By doing this way, one can track who the origin.
If my understand is right, why can’t this be done with a normal database ?
