But on which blockchain can I verify that Aura is the right blockchain to verify Prada?
Prada blockchain NFC tags:
The NFC tags are just a dumb URLs IIUC:
Even though even item in the store had them, and this is a fairly recent initiative, the URLs seem to be broken:

Discussion
Serious answer: the fact that these NFC tags are present on clothing at the Prada store in the stupidly expensive and high profile Dubai Mall, right next to the Burj Khalifa, is solid social evidence that the Aura Blockchain is the legit one.
Which actually means these NFC tags are undercutting some of the purpose of the high end Prada retail stores...
