The public distribution system (PDS) plays a vital role in eradicating hunger and ensuring food security across the world [1]. However, there are certain challenges like beneficiary identification, inconsistent transaction, diversion of grains during procurement at different stages to the open market, ration shop owners selling subsidized goods at higher prices and most importantly the paper focusses on supply chain leakages [2]. This paper proposes a conceptual model for implementing blockchain in PDS and eradicating all the supply chain leakages and making PDS fair [3]. It first focusses on operations of PDS, then assessing all the possible loopholes and implementing blockchain for removing these loopholes. It proposes the idea in which it leverages the benefits of using smart contract and consortium-based ecosystem that can bring efficiencies in PDS.
