Hailed as one of the leading blockchain solutions in the world the De Beers initiative, first launched in 2018, tracks a diamonds 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 in particular due to social, political, and environmental injustice which is rampant in diamond-rich areas and blockchain is the perfect vehicle to provide consumers with the assurance they demand on a product that can be sourced ethically albeit at an increased cost.

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. They are also essentially money and black-markets where these can be sold after they have been stolen from the rightful recipient have emerged in war-torn areas where this aid is most critical. The UN responded with Building Blocks which was 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 then reads their biometric data authenticating them and releasing the vouchers from their linked account ensuring the food will only ever go to the intended recipient.
