Satellite and Blockchain for Transparent and Resilient Disaster Relief

ReliefChain Alliance is a humanitarian technology initiative that combines satellite communication and blockchain transparency to strengthen disaster relief supply chains.

When traditional infrastructure breaks down, ReliefChain Alliance ensures that aid continues to move—reliably, securely, and transparently—from donors to survivors.

Our mission is clear:

• Deliver aid faster and more effectively
• Eliminate fraud and misallocation
• Build trust through full transparency

Disasters expose major gaps in relief delivery:

• Communication networks fail when cell towers go down.
• Donors have no visibility into how their contributions are used.
• Supplies risk being diverted, delayed, or lost.
• Agencies often struggle to coordinate without real-time data.

These gaps cost time, resources, and, most critically, lives.

ReliefChain Alliance integrates resilient communication and transparent record-keeping to create a trustworthy relief ecosystem:

• Satellite Connectivity – Works even when local networks fail.
• Blockchain Transparency – Every transaction and delivery is recorded immutably.
• Real-time Supply Tracking – GPS-enabled packages monitored through satellite.
• Donation Accountability – Donors can see exactly how their support is used.
• Multi-Role Platform – Governments, NGOs, distributors, and beneficiaries work together on one system.

• Frontend: React, Web3.js, Tailwind, Leaflet Maps
• Backend: Node.js, Express, MongoDB, Redis, Socket.io
• Blockchain: Ethereum (Hardhat, Solidity, OpenZeppelin)
• Satellite: Python integrations with Iridium, Inmarsat, and other networks
• Mobile: React Native, with offline-first design for field operations
• Infrastructure: Docker, Kubernetes, GitHub Actions

• Node.js 18+
• Python 3.8+
• Git
• Docker (recommended)
