Secure Ration Provision: Ethereum Blockchain Powered Supply Chain Management for India's Public Distribution System

Abstract

Exploring the Application of Blockchain Technology in India's Public Distribution System (PDS), this paper addresses inefficiencies within the supply chain and enhances its transparency. The focus is on developing a Decentralized Application (dApp) for the PDS, with the primary aim to improve transparency and efficiency and ensure food security among millions of vulnerable individuals. The proposed system provides a transparent and immutable record of transactions throughout the supply chain, enhancing overall efficiency and effectiveness while addressing issues of accountability and data integrity. The methodology involves developing a comprehensive system architecture for integrating blockchain into the existing PDS infrastructure and creating a permissioned blockchain network to ensure only authorized participants engage. This has implications not only for PDS management but also for similar systems globally.
