De Beers Assures Provenance & Authenticity

Tamper-proof source assurance at scale for the global diamond supply chain.

Hailed as one of the leading blockchain solutions in the world, the De Beers initiative — first launched in 2018 — tracks a diamond's journey through the entire value chain, from mine to retailer. It provides "tamper-proof source assurance at scale," offering purchasers an immutable record of the diamond's origins. Source transparency is increasingly in demand in this market due to the social, political, and environmental injustice rampant in diamond-rich areas. Blockchain is the perfect vehicle to provide consumers with the assurance they demand on a product that can be sourced ethically.

UN Distributes Aid in Refugee Camps to Prevent Theft

Biometric blockchain authentication ensures food vouchers reach only their intended recipients.

Food vouchers are an important part of international aid — they enable people to afford food locally and make their own choices before the point of purchase. Black markets for stolen vouchers have emerged in war-torn areas where aid is most critical. The UN responded with Building Blocks, initially deployed throughout refugee camps in Jordan. Refugees can now enter grocery stores and buy food simply by looking at a small machine by the cash register. An iris scanner reads their biometric data, authenticating them and releasing vouchers from their linked account — ensuring food will only ever go to the intended recipient.
