Maureen Downey launched the Chai Vault, an unprecedented solution for securing the authenticity and provenance of fine wine. Wine authenticated through The Chai Method® (TCM®) is certified on the blockchain, creating a permanent, digital record of provenance that can be accessed throughout a bottle’s lifetime journey. Authenticity and provenance data including detailed notes and photographs, the bottles’ unique ID, or “thumbprint,” and a virtual inspection certificate exist in the blockchain and can be kept private or made public for marketing purposes.
