Public Distribution System Using Blockchain Technology

Abstract

In India, the government-run Public Distribution System (PDS) program offers qualified households subsidized food and other necessities. The PDS aims to eradicate food insecurity for the underprivileged and vulnerable people of society, especially in rural areas. Under the PDS, the government offers eligible households basic grains like rice and wheat as well as other necessities like sugar, kerosene, and cooking oil at discounted prices. However, there are numerous issues with the present food supply chain system, which results in a lack of responsibility, transparency, and assurance. In this paper, we suggest a blockchain-based approach to resolve these problems by offering a secure and transparent mechanism for food distribution to the public. From the point of origin of the food goods to the final customer, our system's immutable record of all transactions is kept on a decentralized blockchain network. All participants in the food supply chain, including distributors, retailers, and consumers, are guaranteed access to up-to-date information about the food's provenance, quality, and safety because of this system.
