In a world where global connectivity allows for immediate awareness of humanitarian crises, one persistent challenge remains: getting aid into the hands of those who need it most. Despite generous international donations of money and supplies, inefficiencies in distribution systems often prevent relief from reaching vulnerable populations. Now, the United Nations is turning to an innovative solution — blockchain technology — to bridge this gap and ensure aid reaches refugees efficiently, securely, and transparently.
The Problem: Aid That Never Arrives
When natural disasters or conflicts displace thousands, the global community typically responds with financial support and essential supplies. However, traditional aid distribution systems are often hampered by bureaucratic delays, corruption, and high transaction costs. In refugee camps, these inefficiencies can mean the difference between survival and starvation.
Even well-intentioned programs face logistical hurdles. Cash transfers may be lost in banking fees, physical goods might be diverted before reaching recipients, and identity verification processes can exclude those most in need. These systemic flaws have long undermined the effectiveness of humanitarian efforts.

Blockchain to the Rescue: The WFP’s Building Blocks Initiative
Recognizing these challenges, the United Nations’ World Food Programme (WFP) launched a pioneering project called Building Blocks. Since May, the WFP has successfully used Ethereum-based blockchain technology to distribute over $1.4 million in food vouchers to 10,000 Syrian refugees in Jordan.
Instead of relying on cash or physical cards, refugees at participating supermarkets in Jordan’s refugee camps use iris scanning technology at checkout. The system verifies their identity and records the transaction directly on a private blockchain ledger. No physical money changes hands — just a secure, tamper-proof digital record of each purchase.
This approach eliminates the need for third-party financial institutions, significantly reducing transaction fees. According to Houman Haddad, the project’s lead, blockchain not only cuts costs but also enhances privacy, security, and transparency in aid distribution.
“Every transaction is recorded in real time,” Haddad explains. “We can track exactly what’s being bought, when, and by whom — all while protecting the dignity and data of the recipients.”
Scaling Up: A Vision for 100 Million Transactions
Haddad’s ambitions extend far beyond a single pilot program. He envisions a future where blockchain enables one million daily transactions across multiple humanitarian operations. By January, the WFP aims to expand the Building Blocks system to serve 100,000 refugees, with plans to cover all 500,000 Syrian refugees in Jordan by April of next year.
To achieve this scale, the WFP is actively seeking collaboration with developers, technologists, and other aid organizations. Haddad recently spoke at an Ethereum developers’ conference, calling for global talent to join the effort and help refine the platform for broader deployment.
The goal is not just efficiency — it’s empowerment. By giving refugees direct access to aid through secure digital identities, the system reduces dependency on intermediaries and puts control back in the hands of individuals.

Why Blockchain Works for Humanitarian Aid
Several core features of blockchain make it uniquely suited for humanitarian applications:
- Transparency: Every transaction is permanently recorded and auditable.
- Security: Data cannot be altered once written, preventing fraud.
- Efficiency: Eliminates middlemen and reduces processing times.
- Privacy: Biometric authentication protects user identity without exposing sensitive data.
- Traceability: Donors and agencies can see exactly how funds are used.
These benefits align perfectly with the needs of modern aid delivery — especially in regions with weak infrastructure or unstable financial systems.
Challenges Ahead: Interoperability and Adoption
Despite its promise, blockchain is not a silver bullet. One major hurdle is interoperability. As Paul Currion, founder of the blockchain nonprofit Disberse, points out: “We can’t just hand someone a ticket and tell them to jump on the blockchain train. We have to bring them along the entire journey.”
Different organizations often use incompatible systems, making coordination difficult. For blockchain to reach its full potential in humanitarian work, there must be standardized protocols and shared frameworks that allow seamless integration across agencies.
Additionally, adoption requires training, infrastructure investment, and cultural shifts within large institutions. Resistance to change — especially in risk-averse environments — can slow progress.
Real-World Impact: Stories from the Camps
Behind the technology are real people whose lives have been transformed. Refugees report feeling more dignified using iris scans instead of carrying paper vouchers or standing in long lines for cash assistance. Parents can now reliably feed their children without fear that aid will be misdirected.
One refugee woman described the experience: “It feels like I’m part of the modern world again. I don’t have to beg or wait. I go to the store like anyone else.”
These small moments of normalcy are powerful reminders of why innovation in aid matters.
The Future of Aid: Digital Identity and Financial Inclusion
The Building Blocks initiative could pave the way for broader financial inclusion. With a secure digital identity anchored on blockchain, refugees gain access not only to food aid but potentially to banking, education, and employment services — even across borders.
As Haddad puts it: “This isn’t just about feeding people today. It’s about giving them the tools to rebuild their lives tomorrow.”

Frequently Asked Questions (FAQ)
Q: What is blockchain, and why is it useful for humanitarian aid?
A: Blockchain is a decentralized digital ledger that records transactions securely and transparently. It helps humanitarian organizations reduce costs, prevent fraud, and ensure aid reaches intended recipients without relying on traditional banking systems.
Q: How do refugees use blockchain-based food vouchers?
A: Refugees shop at designated stores and pay using iris scanning technology. Their identity is verified instantly, and the transaction is recorded on a blockchain ledger — no cash or cards needed.
Q: Is personal data safe on the blockchain?
A: Yes. The WFP uses a private blockchain where personal information is encrypted and access is tightly controlled. Biometric data is stored securely and used only for authentication.
Q: Can this system work in other countries?
A: Absolutely. While currently focused on Jordan, the WFP plans to expand Building Blocks to other regions facing humanitarian crises, provided local infrastructure supports biometric verification and digital payments.
Q: Does blockchain eliminate corruption in aid distribution?
A: While not foolproof, blockchain greatly reduces opportunities for fraud by creating an immutable audit trail. Every transaction is traceable, making it harder for funds to be diverted.
Q: Who funds the Building Blocks project?
A: The initiative is funded through a combination of UN budgets, donor contributions, and partnerships with technology providers committed to social impact.
