Abstract: A country's public distribution system (PDS) is crucial in eradicating poverty and ensuring food security. To evaluate the viability of adopting blockchain to remove inefficiencies and provide confidence in the framework, this study presented a blockchain with MongoDB. This paper proposes a comprehensive web-based system with the majority of the features and functions required to manage all forms of interactions between the central government, state governments, district offices, ration shops, and customers. As a result, all transactions are recorded in the blockchain network that connects the various components. This study looks into the feasibility of implementing the proposed concept as a blockchain using Ethereum and a decentralised database (MongoDB). The usage of the blockchain system to assure confidentiality is one of the most notable features of this proposed work.

Keywords: blockchain technology; public distribution system; PDS; smart contracts; solidity; Ethereum; MongoDB; transaction; execution cost.
