ABSTRACT

The public distribution system (PDS) of a country plays a vital role in eradicating hunger and ensuring food security. However, operational inefficiencies like poor beneficiary identification, non-uniform transaction records, and lack of integration among stakeholders hinder the success of such a system. This paper proposes a conceptual model to explore the possibility of using blockchain to eliminate such inefficiencies and ensure trust in the system. It first studies the existing operations of Indian PDS and identifies the transactions requiring information exchanges, storage, and verifications. Then, it proposes a blockchain based solution that leverage smart contracts and consortium-based ecosystem that can bring efficiencies in the PDS system. This paper also proposes a conceptual model for off-chain big data and enlists the possible analytics to support the decision-making of various stakeholders. Finally, it explores the suitability of implementing the proposed model as a consortium blockchain using Hyperledger Fabric and big data analytics.

摘要

一个国家的公共分配系统（PDS）在消除饥饿和确保粮食安全方面发挥着至关重要的作用。然而，诸如受益人身份识别不佳、交易记录不统一以及利益相关者之间缺乏整合等运营效率低下，阻碍了这种系统的成功。本文提出了一个概念模型来探索使用区块链来消除这种低效率并确保对系统的信任的可能性。它首先研究印度 PDS 的现有操作，并确定需要信息交换、存储和验证的交易。然后，它提出了一种基于区块链的解决方案，利用智能合约和基于联盟的生态系统，可以提高 PDS 系统的效率。本文还提出了一个链下大数据的概念模型，并利用可能的分析来支持各种利益相关者的决策。最后，它探讨了使用 Hyperledger Fabric 和大数据分析将所提议的模型实施为联盟区块链的适用性。
