Why would a vendor cheat in a database that contains only a list of legitimate parts from the vendor? It is in their interest to sell those parts and not have any knock-offs sold.
The same goes for quality data, mostly because even if the vendor provides it, basically any industry partner will absolutely insist on doing sample tests on the quality anyway. That also doesn't remove the factor where the quality results are cheated before being put on the blockchain.
A blockchain is not very useful when
A) all participants are trusted or
B) there is no incentive to cheat or
C) if there is incentive to cheat there are already countermeasures available that are more useful (ie, doing samples and having a contract that specifies damage payments in case quality does not match)
