A Blockchain and IoT-Enabled Framework for Ethical and Secure Coffee Supply Chains

John Byrd, Kritagya Upadhyay, Samir Poudel, Himanshu Sharma · 5 authors

The global coffee supply chain is a complex multi-stakeholder ecosystem plagued by fragmented records, unverifiable origin claims, and limited real-time visibility. These limitations pose risks to ethical sourcing, product quality, and consumer trust. To address these issues, this paper proposes a blockchain and IoT-enabled framework for secure and transparent coffee supply chain management. The system integrates simulated IoT sensor data such as Radio-Frequency Identification (RFID) identity tags, Global Positioning System (GPS) logs, weight measurements, environmental readings, and mobile validations with Ethereum smart contracts to establish traceability and automate supply chain logic. A Solidity-based Ethereum smart contract is developed and deployed on the Sepolia testnet to register users and log batches and to handle ownership transfers. The Internet of Things (IoT) data stream is simulated using structured datasets to mimic real-world device behavior, ensuring that the system is tested under realistic conditions. Our performance evaluation on 1000 transactions shows that the model incurs low transaction costs and demonstrates predictable efficiency behavior of the smart contract in decentralized conditions. Over 95% of the 1000 simulated transactions incurred a gas fee of less than ETH 0.001. The proposed architecture is also scalable and modular, providing a foundation for future deployment with live IoT integrations and off-chain data storage. Overall, the results highlight the system’s ability to improve transparency and auditability, automate enforcement, and enhance consumer confidence in the origin and handling of coffee products.

Christian Gómez, Benoît Garbinato

Coffee is consumed worldwide, with its supply chain starting with coffee growers, who benefit least from it. Across its production, distribution, and commercialization processes, there are risks and issues that could damage the safety and authenticity of this product. Therefore, the coffee industry is looking for innovative technologies that allow traceability in the coffee supply chain. In this context, blockchain technology offers a promising solution as it supports traceability via a decentralized system that allows immutable records and transparent access; it also promotes collaborative work and removes intermediaries by generating trust between participants. This systematic literature review describes the state-of-the-art in research and development about the use of blockchain technology to improve traceability in the coffee supply chain. We also outline the open challenges that remain to be addressed in this field. We use the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology to achieve this goal. Our findings suggest that the developments are mainly conceptual designs and prototypes, focusing on tracing products and verifying their authenticity using the Ethereum or Hyperledger blockchains. Also, our results show various challenges on the technology side, like efficiency improvements, integration with other technologies, infrastructure, and a lack of standards. There are also challenges at the management level, like the necessity of agreements for traceability processes, data governance, willingness to invest and pay, education, and support to deploy the technology on farms. After overcoming these open challenges, blockchain technology can improve traceability and increase value for stakeholders in the coffee supply chain.

Marios Vasileiou, Leonidas Sotirios Kyrgiakos, Christina Kleisiari, Pantelis Z. Lappas · 10 authors

Abstract The globalization of contemporary Food Supply Chains (FSCs) has introduced complexities involving multiple actors, food product transportation, and diverse information. Traditional information systems in FSCs face challenges in ensuring transparency and traceability due to the inherent complexities of multi-actor involvement, global transportation, and diverse information, making it difficult to ascertain product origin and processes, exacerbating issues such as food loss, safety concerns, and financial hazards. Blockchain technology, in conjunction with ancillary technologies, offers potential solutions to these challenges. This systematic literature review endeavors to comprehensively explore the multifaceted dimensions of blockchain’s role in FSC management, with an emphasis on food safety and traceability, across six thematic areas, each guided by distinct criteria. These areas include general information, FSC application, factors of blockchain adoption, blockchain platform, ancillary technologies, and the related impact of blockchain adoption. From the 2097 documents found, 122 full-text articles were assessed, and 61 were included and classified in this study based on criteria. These criteria underscore blockchain's capacity for transparency, resilience, and sustainability in FSCs. The results further indicate that blockchain's integration within the FSCs has unveiled a tapestry of possibilities and considerations that underpin its transformative potential in business systems. Blockchain’s inherent traits of transparency and immutability can enhance traceability, mitigate food fraud, and facilitate consumer trust, reshaping the information system’s implementation in the FSC landscape. However, challenges such as integration complexities, data quality, scalability, and regulatory concerns should be addressed. Through these challenges, Artificial Intelligence (AI) arises as a potential solution complementing Blockchain. This amalgamation can effectively tackle certain existing obstacles, such as ensuring data accuracy and system compatibility, while providing stronger solutions for food safety and fraud prevention. The implementation of a comprehensive blockchain solution requires strategic collaboration, technological refinement, and regulatory alignment to fully realize its benefits and address the intricate management challenges of traditional FSC information systems.

Interoperable Traceability in Agrifood Supply Chains: Enhancing Transport Systems Through IoT Sensor Data, Blockchain, and DataSpace

Giovanni Farina, Alexander Kocian, Gianluca Brunori, Stefano Chessa · 21 authors

Traceability plays a critical role in ensuring the quality, safety, and transparency of supply chains, where transportation stakeholders are fundamental to the efficient movement of goods. However, the diversity of actors involved poses significant challenges to achieving these goals. Each organization typically operates its own information system, tailored to manage internal data, but often lacks the ability to communicate effectively with external systems. Moreover, when data exchange between different systems is required, it becomes critical to maintain full control over the shared data and to manage access rights precisely. In this work, we propose the concept of interoperable traceability. We present a model that enables the seamless integration of data from sensors, IoT devices, data management platforms, and distributed ledger technologies (DLT) within a newly designed data space architecture. We also demonstrate a practical implementation of this concept by applying it to real-world scenarios in the agri-food sector, with direct implications for transportation systems and all stakeholders in a supply chain. Our demonstrator supports the secure exchange of traceability data between existing systems, providing stakeholders with a novel approach to managing and auditing data with increased transparency and efficiency.

Plastic pollution poses an escalating global threat, with Indonesia ranked among the largest contributors to marine plastic leakage due to inadequate waste management systems. Although blockchain technology has been increasingly applied to enhance transparency in various sectors, its direct integration into plastic waste management remains underexplored. This study proposes a blockchain-based cyberphysical system (CPS) that utilizes fungible tokens (FTs) to represent verified plastic recycling activities and non-fungible tokens (NFTs) as immutable certificates of plastic offset achievements. Smart contracts were developed in Solidity and tested on a local Ganache blockchain by executing 100 sequential minting transactions. Validation results demonstrated an average confirmation time of approximately 1.388 seconds per transaction, indicating strong system performance under continuous load. The proposed model offers a decentralized, verifiable approach to plastic credit management, supporting Indonesia’s efforts toward Sustainable Development Goals (SDGs) 12 and 14.

Sustainable Development of Seafood Supply Chains via Blockchain Technology: Innovation Adoption and Implementation by Businesses and Entrepreneurs

Benjamin S. Thompson, Sascha Rust

ABSTRACT We investigate why and how businesses and entrepreneurs adopt and implement blockchain technology to improve the economic, environmental and social sustainability of seafood supply chains. We conduct interviews with entrepreneurs and small‐ to medium‐sized enterprises (SMEs) – specifically fishers, aquaculturists and restaurants – using new blockchain platforms to increase the traceability and trackability of seafood in Australia. Drawing on innovation adoption theory, we examine drivers and barriers to trading seafood via these innovative platforms, compared to traditional trading routes – such as through wholesalers. Benefits for seafood buyers included greater freshness, less waste, value‐adding the customer experience and supporting locally sourced products. Benefits for sellers included price security and transparency, and the marketing and branding opportunities that the platforms enabled through social media. Challenges regarded distrust, competition, uncertain product availability and the tangibility of seafood, which – unlike cryptocurrency – requires transport, packaging and processing, meaning potential efficiencies could become constrained by supply chain logistics.

Diana Hawashin, Khaled Salah, Raja Jayaraman, Raja Wasim Ahmad · 6 authors

• Proposes a blockchain-based solution to reduce waste in the dairy industry • Ensures waste assessment and accountability through the proposed solution • Tests and validates various scenarios to evaluate the practicality of the system • Presents a security analysis to assess the system's resilience against threats In recent years, the global demand for dairy products has reached unprecedented levels in the food and beverage market. Despite being produced in large quantities to meet daily needs, high organic content in milk causes it to expire quickly, leading to food waste. Current dairy supply chain management systems lack traceability, auditability, and trust relationships, contributing to the problem. To address this issue, we propose a private Ethereum blockchain-based solution that holds all participants accountable and assesses their actions in a decentralized, auditable, traceable, secure, private, and trustworthy manner. Our system consists of various phases managed by four smart contracts that ensure all involved parties are accountable. We use an events-based approach to ensure traceability and data provenance, where all actions are stored on an immutable ledger in the form of events. By providing a transparent and traceable system, it encourages responsible resource utilization and supports a more sustainable approach to dairy production. We present the system architecture, sequence diagrams, entity-relationship diagrams, and algorithms to explain the working principles of our solution. We also validate the effectiveness of our developed smart contracts and make our smart contract code publicly available on GitHub.

A robust food traceability system is crucial for ensuring seamless information flow within supply chains. While the current centralised approach, typically led by a supply chain leader, facilitates information exchange, it faces significant limitations, such as prolonged tracing processes and a lack of transparency. Blockchain technology presents a promising solution to address these challenges. However, concerns persist about the costs of IT infrastructure required to operate blockchain-based systems. This research compares the costs between centralised and blockchain ecosystems, focusing on the total cost for the entire industry, using the Thai broiler supply chain as a case study. We analysed both centralised and blockchain IT models, selecting 13 deployment scenarios for comparison. The Thai broiler supply chain provided data on IT infrastructure usage, with Monte Carlo simulation employed to address undisclosed supply chain data. The IT infrastructure costs for each scenario were calculated and compared. The analysis reveals a significant finding: blockchain implementation results in approximately 43% lower infrastructure costs compared to the practical centralised approach. This cost-effectiveness suggests that third parties, such as government bodies or central regulatory agencies, could play a crucial role in supporting the transition from centralised to blockchain-based food traceability systems, thereby enhancing supply chain transparency, efficiency, and food safety.
