- myth_drannon 9y agoToday we can't.
- mythrwy 9y agoActually I think we could. It just hasn't been implemented. (not to say it's practical).
- diggan 9y agoActually, from the article, it mentions this: > Leanne Kemp, an Australian who in 2015 founded a company called Everledger, has now encrypted the distinguishing features of 1.8 million diamonds and their provenance on a blockchain. > More than 40 features are logged to create a fingerprint for each diamond, logging it from mine to ring. So it seems, in the case of diamonds, they are unique enough to create a fingerprint. I'm no expert on diamonds, so that might not really work in reality.
- Isomatik 9y agoI can't find very much information on Everledger's features process, just on the blockchain aspect, which doesn't inspire confidence. It's not enough for them to create 40 features you can fingerprint a diamond by, they have to be 40 features that are independently and consistently verifiable. If I have to send my diamond to Everledger to verify it, I'm effectively just trusting them. Representing a physical object as a cryptographic hash for security doesn't work if the consumer can't independently verify the hash.
