KRanTi: Blockchain-based farmer's credit scheme for agriculture-food supply chain

The advent of agro-industrialization has helped the agricultural food supply chain (AFSC) in introducing ease and innovation to other facets. In addition, Blockchain (BC) technology is revolutionizing each distributed data-related application by adding authentication and trust among the system's stakeholders. Inspired by the above-mentioned argument, this article proposes a system, KRanTi, to promote the supply chain of agricultural food by BC embedding across the 5G network. The 5G network upgrades the data connectivity by enhancing network infrastructure efficiency. In KRanTi, we present an efficient credit system that enables associated farmers to purchase the requisite agricultural raw product of higher quality without the pressure of instant payment. A score-based farm-food quality assurance system is then proposed, which guarantees optimal quality grading. Trust, transparency, and traceability are preserved through the implementation of Smart Contracts (SC) distributed across public Ethereum BC. The cost-effective off-line data storage service in AFSC is offered through the use of the Inter-Planetary File System (IPFS), a shared storage system to hold all data from stakeholders. Results show that the efficiency of the proposed scheme KRanTi is improved compared with traditional schemes with metrics such as less than 1 millisecond latency with 99.99% reliability compared with LTE with 5G, scalability, packet failure ratio, BC performance, cost-quality ratio, and data storage contrast.

Automated summary

The article introduces a system called KRanTi that aims to improve the agricultural food supply chain by utilizing blockchain technology and 5G network. The system includes an efficient credit system and score-based food quality assurance system to ensure product quality. Additionally, the use of smart contracts and IPFS ensures trust, transparency, and traceability.
