Problem Statement
The lack of a unified digital link between market purchases and export inspections allows mineral weight under-declaration and illegal trade to go undetected, causing severe revenue loss for the nation .
Proposed Solution
A Web3 application that records mineral batches on a shared blockchain ledger, requiring dual officer signatures and automatically blocking export transactions that exceed registered market weights
Innovation
The system moves compliance checks directly into smart contract code to automatically reject invalid weight declarations at execution time while storing miner personal data off-chain for strict privacy compliance.
Expected Impact
MadiniChain stops export revenue loss in real time, eliminates delayed audit backlogs, and builds global trust in Tanzanian minerals through instant QR-code verification.
