LVMH, Richemont and Prada unite behind a blockchain consortium.

Three rival names in the European luxury sector have established a new blockchain consortium that will allow shoppers to track the provenance of their purchases and authenticate goods.

LVMH Moët Hennessy Louis Vuitton, which first unveiled plans for a global blockchain-based system in 2019, will be joined by Prada Group and Compagnie Financière Richemont in the Aura Blockchain Consortium, a nonprofit group that will promote the use of a single blockchain solution open to all luxury brands worldwide.

Many sectors are looking at the possibility of using blockchain, the distributed ledger system that underpins Bitcoin and other cryptocurrencies. Because blockchains are unchangeable and decentralized, the data stored on them is trustworthy and secure.

In this case, each product will be given a unique digital code during the manufacturing process that will be recorded on the Aura ledger. When customers make a purchase, they will be given login details to a platform that will provide the history of the product, including its origin, components, environmental and ethical information, proof of ownership, a warranty and care instructions.

Bulgari, Cartier, Hublot, Louis Vuitton and Prada are already using the system, with “advanced conversations” being held with a number of other luxury brands, according to a statement released Tuesday. Participating luxury brands pay an annual licensing fee and a volume fee. Aura, based in Geneva, was developed in partnership with Microsoft and ConsenSys, a blockchain software technology company in New York.

“The Aura Consortium represents an unprecedented cooperation in the luxury industry,” said Cartier’s chief executive, Cyrille Vigneron, adding that he invited “the entire profession” to join the consortium.

“The luxury industry creates timeless pieces and must ensure that these rigorous standards will endure and remain in trustworthy hands,” he said.
