PARIS: Luxury groups LVMH and Prada along with Cartier announced Tuesday they are joining forces on a blockchain that will allow consumers to authenticate their goods.

Called the Aura Blockchain Consortium, the initiative will offer a secure method for consumers to access information about to a product’s history, including the materials used and craftmanship. Luxury groups have long worried about fake copies of their products, and they are keen to let customers know about how they are made in order to build their brands. “Consumers can easily and transparently follow a product’s lifecycle, from conception through distribution, with trusted data throughout, and thus strengthen their relationship with their favourite luxury brands,” the companies said in a statement.

A blockchain is in essence a ledger that is shared publicly. They are used by cryptocurrencies as transactions can registered securely and followed publicly, but blockchains are also being used for recording a variety of information to be shared publicly. The Bulgari, Cartier, Hublot, Louis Vuitton and Prada brands are already active on the platform, the statement said, adding that discussions were underway for others to join.
