How the United Nations is using blockchain to bring stability to the lives of refugees.
The future of world food aid arrived, in early May, unnoticed by its first recipients: the grocery shoppers inside a supermarket at the Azraq camp in Jordan, home to 36,000 Syrian refugees. To be fair, their buying process already looked pretty high-tech, especially for a store with a dirt parking lot in the middle of the desert. Before paying, each shopper peered into a black, rectangular iris scanner mounted at eye-level, which confirms users’ identities with the camp’s organizing group, the United Nations High Commissioner for Refugees, and allows them to access a food stipend from the United Nations’ World Food Programme (WFP).
That’s a spiffy authentication process, but it had been there for months. What the shoppers didn’t see was the new back-end procedure. Instead of receiving WFP funds via a third party, such as a bank, the grocery store was reconciling each purchase directly with the aid group through a secure platform called Building Blocks, based on blockchain technology. Inside the store, Houman Haddad, a finance officer for the WFP and the founder of Building Blocks, watched as each eye scan led to a cashier’s tablet flashing a green check mark, signaling a completed transaction. “It was the moment when I knew this was technically possible,” he says.

But, as with everything, work trips are not what they were in 2019. From airlines to banks, companies are finding new ways to make business travel easier-and even a little fun.
