A Web Based Blockchain System for Decentralized Location Identification in Africa # SpaceID A Web-Based Blockchain System for Decentralized Location Identification in Africa ## Overview SpaceID is a blockchain-based system that provides every registered physical location with a unique digital identity. Built on the Ethereum Sepolia Testnet, SpaceID addresses the challenge of unreliable location identification in many African countries where standardized addressing systems are incomplete or unavailable. ### Problem Statement Many homes, businesses, schools, farms, and public facilities in Africa cannot be identified using a standardized address. People often rely on landmarks such as "behind the church" or "next to the market" to describe locations. This creates difficulties for: - Emergency responders - Delivery services - Ride-hailing platforms - Property management - Government services - Tourism - Businesses ### Solution SpaceID creates a secure and verifiable digital identity for physical locations using blockchain technology. Each location receives a unique SpaceID that is deterministically generated from geographic coordinates and blockchain transaction data, ensuring global uniqueness and resistance to duplication. **Example SpaceID:** `SPC-RWA-KGL-a3f7b2c9` ### Mission Alignment This project aligns with the mission: *"To design and develop secure, efficient, and accessible technology systems that improve education, strengthen digital security, and support innovation in Africa through practical software engineering solutions."* SpaceID applies blockchain technology to solve a real infrastructure challenge while promoting secure, trustworthy, and decentralized digital systems. ## Features - **Register Locations**: Register physical locations with geographic coordinates - **Unique SpaceIDs**: Generate globally unique, hash-based SpaceIDs - **Duplicate Prevention**: Prevent duplicate registrations at the same coordinates - **Verification**: Verify registered locations and retrieve information - **Ownership Management**: Transfer …
