Blockchain-Based Traceability for the Fishery Supply Chain

Abstract

Efficient traceability management is necessary for managing products in the fishery supply chain. Any negligence in products' traceability can result in food fraud that may adversely affect the consumer's health. Monitoring and tracking of the fishery supply chain operations can assist system stakeholders in identifying the origins and causes of product fraud and malpractice. Most of the existing systems and technologies used to manage the fishery supply chain processes fall short of providing traceability, accountability, transparency, reliability, trust, privacy, and security features. In this paper, we propose a private Ethereum blockchain-based solution to efficiently manage the fishery supply chain operations in a manner that is decentralized, transparent, traceable, secure, private, and trustworthy. We present the solution architecture and propose five smart contracts to automate the processes in fishery supply chain. We present ten algorithms along with their full implementation, testing, and validation details. We conduct a security analysis to show that the proposed solution is both secure and trustworthy. We compare our solution with the existing blockchain and non-blockchain-based solutions to show its effectiveness and novelty. We make the smart contract code publicly available on GitHub.

A qualitative analysis of rural fishermen: Potential for blockchain-enabled framework for livelihood sustainability

“…Where consumers are losing trust in the sources of their seafood and storage mechanisms, blockchain technology has the potential to remedy this and rebuild trust [45] . A well-designed private blockchain solution based on the Ethereum platform that utilising five smart contracts for tracking and authentication was proposed to help authorities prevent food fraud (e.g., substitution of valuable species with cheaper ones, and selling frozen-thawed products as fresh fish), and mitigate health risks for consumers [46] .…”

A Blockchain-Based Fish Supply Chain Framework for Maintaining Fish Quality and Authenticity

“…This framework incorporates the use of BC, satellite imagery, and IoT technologies. The authors of [21] proposed a BC-based fish traceability solution for handling both wild-caught fish and farmed fishery SC aiming to prevent fraudulent activities. The authors of [22] discussed a framework that combined BC, IoT, Cloud Computing, and AI technologies to implement SCs.…”

An Examination of Distributed and Decentralized Systems for Trustworthy Control of Supply Chains

“…• They proposed a fivestep procedure that should be strictly followed during a systematic review. [35].…”

“…It is imperative to implement this idea without any delay. To develop a distributed, accessible, confidential, safe, and reliable network that intends to streamline the aquaculture supply chain, the writers suggest a blockchain-based system that uses ethereum [35]. The proposed system has five smart contracts in place to achieve this end.…”
