Grainbee: A Quantum-Resistant Blockchain-Based Ration Distribution System with Hardware Security Modules

In developing countries, subsidized food programs aimed at supporting the poor are often undermined by corruption and mismanagement, leading to food waste and unequal distribution. To overcome these challenges, we introduce GrainBee, a blockchain-powered ration distribution system designed to ensure secure, transparent, and efficient food supply distribution. By leveraging blockchain’s inherent security and immutability, GrainBee addresses the major security and transparency issues that plague traditional and existing blockchain-based systems.Our proposed system employs a post-quantum secure, blockchain-based approach to combat corruption and fraudulent invoicing, guaranteeing integrity through a distributed, immutable ledger. To further fortify security, we integrate Hardware Security Modules (HSMs), providing an additional layer of protection for sensitive data and transactions. A built-in reservation and scheduling system streamlines the distribution process, while a user-friendly interface and machine translation services bridge language gaps, enhancing usability and accessibility. By harnessing the power of blockchain technology, GrainBee offers a robust solution to the complex challenges of food distribution.
