Revolutionizing the Farm-to-Table Journey: A Comprehensive Review of Blockchain Technology in Agriculture Supply Chain

Literature Review

In Revathy and Sathya Priya (2020), blockchain based producer consumer model (BPCM) aims to bridge the gap between farmers and consumers by enabling direct transactions through a blockchain-based platform. The purpose is to eliminate intermediaries, provide transparency and control over prices for farmers, and ensure quality for consumers. The deliverables include a BPCM with unique identities for all participants and smart contracts that authenticate transactions. The challenges include the vulnerability of IoT devices to security attacks, such as DoS, energy exhaustion, node capture, and Sybil attacks. The gaps in the literature include a lack of research on the effectiveness of BPCM and the need for further investigation into the security of IoT devices in blockchain-based systems. The inference is that BPCM can enhance the trust and transparency of all transactions, but its implementation must address security concerns. The methodology used is Ethereum, a public blockchain that operates in a permissionless environment, with nodes connected in a blockchain. The advantages of BPCM are transparency, no travel, no rent, and no middleman, while the disadvantages are security risks and the need for further research.
