SafeGrains – Bringing Accountability to Public Distribution System using Blockchain

Abstract
To maintain food security, the Indian government's central and state governments use the Public Distribution System (PDS) to supply food grains at subsidized rates to Indian citizens. Because of widespread corruption among the officials who serve the system, as well as physical losses during storage and transportation, the system is prone to food grain losses. Because of its fundamental nature as a distributed ledger for recording transactions, blockchains have become a widely utilized audit trail verification tool. As a result, it's a strong contender to replace the PDS's present centralized system for tracking commodities provided. In this project, we've described a Blockchain-based prototype that the Indian government can utilize to rule. MGNREGA (Mahatma Gandhi National Rural Employment Guarantee Act) and PDS (Public Distribution System). Many frauds and corruptions occur in these schemes, such as when food does not reach the impoverished or wagers are not paid as planned. This project aims to create a Blockchain prototype that can record and log all of these schemes' transactions. For the PDS plan, a complete end-to-end web-based blockchain prototype application with all the features and functionalities to carry out all types of transactions by the central government, state governments, fair pricing retailers, and customers in the system has been constructed.
