A Blockchain Enabled Trusted Public Distribution Management System Using Smart Contract

Nowadays, a large population of hungry people still exists in many countries. The government body of most countries in the world tries to provide food security to every citizen. They have implemented many rules to provide food safety for citizens. They also run many Public Distribution Shops (PDS) to distribute food products and essential commodities at low prices. But existing systems face many challenges in terms of low accessibility like buying items from the same PDS, transaction transparency, PDS trust, centralized system, and much more. So, to overcome these limitations, a Blockchain-enabled trusted public distribution framework has been proposed using smart contracts. The design and development of smart contracts will not only provide food security but can deliver transparency in the system, which leads to building trust in the system. Therefore, the concerned authorities of the distribution system can build trust with each other efficiently and reliably. In the proposed framework, people can also buy commodities from different PDS creating high accessibility to the system. The proposed work also provides secure communication among authorities and transparency and security of the management data.
