A “blockchain” warranty certificate at Ulysse Nardin
Ulysse Nardin is the first luxury manufacturer to deploy blockchain certification to all its collections. Remember that blockchain is a technology that can be used to store and transmit information or transactions. It is a global digital database shared among multiple users that can, at any time, using a cryptographic system, verify the validity of information, add data and record a transaction. Ulysse Nardin’s approach used here is to store the “digital signature” of all PDF warranty certificates in the form of a “hash” – i.e. an encrypted string of characters – on the Bitcoin blockchain. Therefore, a digital document like a warranty certificate in this case, when protected on the blockchain, becomes tamper-proof. Another advantage is that this certificate becomes extremely useful for the after-sales service (a reliable transaction history) or when it is offered as a gift or resold (used market).
