Blockchain is being used by the United Nations and NGOs to deliver humanitarian aid faster, cheaper, and more securely. Programs like the UN’s Building Blocks project use blockchain to give refugees cashless access to food and supplies, cutting banking costs by up to 90%. Similar blockchain applications now support smallholder farmers, unbanked gig workers, and food-safety tracking in crisis-affected regions.
Why Humanitarian Organizations Are Turning to Blockchain
When people think about industries blockchain will transform, they usually picture finance, supply chains, or voting systems — not refugee camps. Yet the United Nations has been running some of the world’s largest blockchain-based humanitarian programs for years, using the technology to move aid faster, cut fraud, and reach people who have no access to traditional banking.
Here’s how three real UN-backed initiatives are putting blockchain technology to work and what businesses can learn from them.
Building Blocks: Cashless Aid for Refugees
The UN World Food Programme’s Building Blocks project gives refugees a secure, cashless way to receive aid. Instead of carrying cash or vouchers, refugees are identified through biometric eye-scan data linked to UNHCR’s identification system. Purchases at camp supermarkets are recorded on a blockchain ledger shared with vendors no cash changes hands, and no names, birthdates, or fingerprints are stored on-chain.
The results are significant:
- Local banking costs cut by roughly 90% (2018 data)
- Over 1 million refugees supported across Bangladesh, Lebanon, and Jordan
- US $325 million in aid distributed since 2017 — the largest blockchain-powered humanitarian program in the world
- Refugees build a transaction history, helping them access financial services without navigating traditional banking bureaucracy
Because identity data is anonymized, the system also protects vulnerable users from the security risks that come with centralized data storage.
Decapolis: Supporting Smallholder Farmers
Smallholder farmers in crisis-affected regions face compounding problems: limited access to water and energy, broken supply chains, and no reliable way to prove their produce meets safety standards. The WFP Jordan Innovation Hub’s Decapolis program addresses this with a blockchain-based supply chain that tracks food from farm to retail.
Farmers get training in agricultural best practices pesticide management, contamination prevention and can register their produce on Decapolis to verify it meets domestic and international food-safety standards. Buyers can then browse and purchase only verified goods. The program has already supported around 100 farmers, with plans for a food-health tracking system to flag risks from unverified suppliers.
EMPACT: Bringing the Unbanked into the Digital Economy
The global gig economy is projected to be worth hundreds of billions of dollars, but more than 170 million young people in low-income regions including refugees and displaced people are locked out of it due to limited tech access and no banking history.
EMPACT trains young people in IT skills and connects them to online job markets, while using blockchain development to solve the “unbanked” problem: workers can receive and track payments without a traditional bank account, avoiding the high fees typically attached to cash transfers for small, informal work.
What This Means for the Future of Blockchain in Aid
The UN’s long-term goal is to scale these pilot programs into a broader model for sustainable development. To support that, it created The Atrium a collaboration platform where humanitarian organizations share blockchain research, tools, and lessons learned, including a public GitHub library of UN blockchain applications.
These programs matter beyond the humanitarian sector. They demonstrate blockchain’s core strengths at scale: secure identity without centralized data risk, transparent supply chains, and low-cost financial access for people traditional systems overlook. Businesses evaluating blockchain for supply chain, identity, or payments use cases can look to these deployments as proof the technology works under real-world constraints not just in theory.
What’s notable is the scale at which these systems now operate. Building Blocks alone processes millions of transactions across multiple countries without a central database of personal information, and it has run continuously since 2017 without a major security failure. For an industry still fighting perceptions of instability and risk, that track record is one of the strongest real-world arguments for blockchain adoption available today.

Frequently Asked Questions
What is the UN's Building Blocks blockchain project?
Building Blocks is a UN World Food Programme initiative that uses blockchain and biometric identification to let refugees make cashless purchases at camp supermarkets, cutting banking costs and improving aid delivery security.
How does blockchain help unbanked populations?
Blockchain lets people transact and build a financial history without a traditional bank account, lowering the fees and barriers associated with cash transfers which is especially valuable for refugees and gig workers in low-income regions.
Is blockchain actually being used in humanitarian aid today?
Yes. Programs like Building Blocks, Decapolis, and EMPACT are active UN- and NGO-backed initiatives, not pilots or concepts Building Blocks alone has distributed over $325 million in aid since 2017.
Can businesses apply these same blockchain principles?
Yes. The same core capabilities secure identity, transparent supply chains, and low-cost digital payments apply directly to commercial use cases in finance, logistics, and cross-border payments.
