That you for bringing for this intriguing idea for discussion! Supply chain tracking of the sort you describe is excellent for tracking packages and the movement of goods. It's very useful for tracking the inputs to and outputs from a manufacturing process. Perhaps it's just my personal failure to understand your proposal, but this approach seems mainly limited to tracking known and expected inputs. So it might have a hard time detecting some nigh-invisible addition that takes place within an existing stage of manufacture and does not result in any additional attestation. Can you help me understand? How does a blockchain solve the problem of a fabrication step compromised?
