How do I know if the wine in the bottle and what is on the blockchain are the same?

At Everledger we call this the ‘last-mile problem, and that is what happens between that digital asset and the offline world. For wine, in particular, there’s a security layer needed to preserve its forensic identity — that is its chemical composition and its verifiable origin. This is where tamper-resistant capsules and secure NFC technology come in. A tap with your smartphone not only opens a digital experience that shows the provenance of the wine, but also offers options to authenticate, purchase or claim ownership. Bottle’s that have been opened, siphoned or otherwise manipulated are reported as such when scanned.
