"Unlike algorithms, QMC does not use cryptography to register the Tags and therefore cannot be hacked. I have no proof of this other than what I read in my DD and interpretation of what the company has stated. FWIW!"

Why blockchain? Because once data is recorded on a blockchain it cannot be modified - so it cannot be hacked or tampered with. Blockchains are secured by cryptography originally developed by the NSA. Also, blockchains allow the same set of data to be shared among many participants. It is the same data, not local copies. This means that all participants in a supply chain from the point of manufacture to point of retail sale have access to the same original digital signature to ensure that a product is authentic.
