A Londres, ce matin, le train pour la blockchain était au quai à 8h30… c’est tôt.  J’ai pu évoqué les transitions sociétales que pouvait accompagner Blokchain, en évoquant la question du pourquoi? plutôt que du comment?

J’avais la chance de présenter aussi Leanne Kemp de EVERLEDGER qui utilise la blockchain dans le domaine de la supply chain. Un sujet qui touchait tout le monde dans la salle : 300 CDO français venu à Londres pour partager autour du digital.

A diamond’s past is rarely crystal clear. Knowing a stone’s origin can stop fencing and insurance frauds and winnow out synthetic diamonds or those sourced in war zones. But forged paper certificates make provenance hard to verify.

That’s why in May 2015 Leanne Kemp founded Everledger, a global digital registry for diamonds, powered by the blockchain – the decentralised ledger underpinning cryptocurrencies such as Bitcoin. « Blockchain is immutable; it cannot be changed, so records are permanently stored, » says Kemp. « Information on the blockchain is cryptographically proven by a federated consensus, instead of being written by just one person. »

Everledger uses more than 40 features, including colour and clarity, to create a diamond’s ID. Enshrined in the blockchain, this information becomes a certificate chronicling the jewel’s ownership, from mine to ring. Everledger has digitised more than a million diamonds and partnered with firms including Barclays.
