In the field of raw food and seafood transportation, the importance of real-time temperature control and monitoring cannot be overstated. The assurance of product safety throughout the transport will enhance the product’s trustworthiness which is one of the factors that customers consider while deciding whether to utilize the service. This paper presents the concept of the cold chain system using Internet of Things devices and blockchain technology. The device collects temperature and geolocation and sends it to Hyperledger Sawtooth, a key blockchain infrastructure that has been chosen. The idea behind the application is to allow consumers to track products through a supply chain and notify the driver when the container’s temperature is out of the range. In order to record the shipment log as a blockchain transaction, we connected the application, the devices, and the blockchain database together. This concept can guarantee the integrity, trust, and traceability of the data because no one has the authority to change, modify or delete any information.

Abstract Ensuring high quality and safety of food products has become a key factor on one hand to protect and improve consumers health and, on the other one, to gain market share. For this reason, much effort in the last year has been devoted to the development of integrated and innovative Agriculture and Food (Agri-Food) supply chains management systems, which should be responsible, in addition to track and store orders and deliveries, to guarantee transparency and traceability of the food production and transformation process. In this paper, differently from traditional supply chains which are based on centralized systems, we propose a fully distributed approach, based on blockchain technology, to define a supply chain management system able to provide quality, integrity and traceability of the entire supply chain process. The proposed framework is based on the Hyperledger Fabric technology, which is a permissioned blockchain system: a prototype has been developed and, by using some use cases, we show the effectiveness of the approach.

Based on the advantages of Big Data and blockchain in food traceability area and information sharing area, it has attracted widespread attentions. However, it is not so popular in agricultural field, a vital reason is the scarcity of effective incentives. Government incentive as an important incentive measure is thought to be useful. To study the subsidy rules in the new background, we chose an agri-food supply chain with one producer and one retailer as research object and divided government incentive into direct incentive and indirect incentive. Then, considering the changes of consumer perceived safety on agri-food in the new environment, the demand function was revised. Furthermore, we proposed and analyzed three subsidy models and their benefit functions considering the information service inputs based on Big Data and blockchain (BBIS). Findings: (1) The subsidy models will not change the variation tendency of prices and benefits with the BBIS optimization coefficient, the BBIS investment costs from the producer and the retailer, the ascension of the unreliability coefficient of quality safety and the agri-food quality level. (2) When the subsidy coefficients about direct and indirect subsidies can meet a relationship, benefits of chain members in the indirect subsidy model are higher than them in the direct subsidy model. Findings offer a theoretical guidance for government departments to make and implement the subsidy strategies. In addition, for company, it can provide a theoretical guidance on setting pricing strategies in the new technology background.

The European Union aims for Member States to achieve climate neutrality by 2050. To this end, the European Commission has launched a set of policy initiatives in The European Green Deal. One of the components is the Farm to Fork strategy, through which the European Union aims to increase, among other things, to 25% of the agricultural areas with organic production, as well as new labeling rules to promote the sustainable consumption of food and organic food. A modern technology that can be used for food traceability is Blockchain technology. The main objective of this paper is to study consumers' perceptions of the possibility of using blockchain technology in the distribution of "organic" food products. The research was quantitative and followed the specific aspects of the blockchain concept and its use in the distribution and tracking of food and ecological goods, "organic". The aim of the research was to develop a predictive model, using the basic regression equation, to obtain a positive perception of the use of blockchain technology for food and environmental goods.

Purpose Warehouse receipt system (WRS) schemes aim to revitalize the market of cash crops, particularly those of the smallholder farmers. However, the existing government schemes for the smallholder farmers have not been much successful on account of issues related with transparency and trust deficit, thereby limiting farmers' access to credit for their farming activities as channeled via the formal financial institutions. Conceding that blockchain is an emerging technology, this study aims to theoretically posit the potential to optimize WRS in real time to bolster farmers' trust and privacy. Design/methodology/approach The research bases itself on the design science research (DSR) approach. Using the DSR approach backed by the literature review and evolutionary prototyping, a blockchain-based WRS has been advanced in the study. Findings This study provides a design of a digital WRS, which serves as a proof of concept of blockchain technology (BCT) applications in improving transparency in the WRS in the agricultural sector. The findings from this study present the possibility of leveraging blockchain smart contracts to improve the linkages between the WRS stakeholders to promote trust and transparency that would eventually unlock the potentials of WRS schemes. Furthermore, the findings inform decision-makers and practitioners to prioritize the emerging technologies in revamping the classical WRS. Research limitations/implications The study leaves research pointers for implementing BCT in agricultural supply chain and furthering the findings from the present study with an empirical agenda. Originality/value Whilst research on the BCT applications across myriad sectors abounds, research on the BCT applications to address societal needs is conspicuously limited. Furthermore, research on the practical implementation of the BCT in real-world scenarios is few and far between. The present study seeks to plug these gaps by underlining the application and utility of blockchain in WRS. The study makes a significant contribution to the theory and practice of the agrarian supply chain management, specifically the WRS, by invoking design knowledge obtained through an iterative design process besides serving as an edifice for the integration of emerging technologies, notably BCT in the agricultural sector.

Food safety is a fundamental right in modern societies. One of the most pressing problems nowadays is the provenance of food and food-related products that citizens consume, mainly due to several food scares and the globalization of food markets, which has resulted in food supply chains that extend beyond nations or even continent boundaries. Food supply networks are characterized by high complexity and a lack of openness. There is a critical requirement for applying novel techniques to verify and authenticate the origin, quality parameters, and transfer/storage details associated with food. This study portrays an end-to-end approach to enhance the security of the food supply chain and thus increase the trustfulness of the food industry. The system aims at increasing the transparency of food supply chain monitoring systems through securing all components that those consist of. A universal information monitoring scheme based on blockchain technology ensures the integrity of collected data, a self-sovereign identity approach for all supply chain actors ensures the minimization of single points of failure, and finally, a security mechanism, that is based on the use of TinyML’s nascent technology, is embedded in monitoring devices to mitigate a significant portion of malicious behavior from actors in the supply chain.

Food safety is a public health issue of paramount importance. In this regard, blockchain has emerged as a promising technology that allows users to effectively and efficiently record the origin and flow of products and eliminate or reduce harmful food fraud. Consumers can benefit from this development by receiving up-to-date and verifiable information about the origins and delivery routes of their purchases. Drawing on signaling theory and the results of two experimental studies with 151 and 152 participants, respectively, we investigate how the use of blockchain to trace food products impacts consumers’ perception of product quality as a mediating variable and subsequently their purchase intention. Our framework further considers brand familiarity as a moderating variable. The findings from the two experiments show that blockchain labels as a signaling mechanism in food supply chains help to strengthen consumers’ perceived quality of food products, which, in turn, increases their purchase intention. This effect is more pronounced for less familiar brands, which is valuable information for managers who want to build a brand’s reputation. From an academic perspective, we highlight the applicability of signaling theory to identify blockchain-based traceability systems as important drivers of perceived product quality and consequently purchase intention.

Rice is a major food crop around the world, and its various quality and safety problems are closely related to human health. As an important area of food safety research, the rice supply chain has attracted increasing attention. Based on blockchain technology, this study investigated problems of data privacy and circulation efficiency caused by complex rice supply networks, long circulation cycles, and various risk factors in each link. First, we deconstructed the quality and safety of each link of the rice supply chain at the information level and established a key information classification table for each link. On that basis, we built a rice supply chain information supervision model based on blockchain. Various encryption algorithms are used to secure the sensitive data of enterprises in the supply chain to meet regulators' needs for efficient supervision. Moreover, we propose a practical Byzantine fault-tolerant consensus algorithm that scores the credit of enterprise nodes, optimizes the selection strategy of master nodes, and ensures high efficiency and low cost. Then, we built a prototype system based on the open-source framework of hyperledger fabric, analyzed the model's viability, and implemented the system using cases. The results indicated that the proposed system can optimize the information supervision process of rice supply chain regulators and provide a feasible solution for the quality and safety supervision of grain and oil.

Agri-foods that generally made purchased at traditional markets are now increasingly made purchased at modem trade market chains - supermarkets, particularly developing country. This offers particular opportunity for food producers if they can adhere to the exacting supplier standards and systems dictated by supermarket chains particularly quality assurance. Rural farmers can find themselves excluded from dealing with such bodies because they do not have the resource to implement the necessary systems to guarantee process quality. There is increasing need to develop more efficient and effective logistics operation in order to better integrate Thailand’s agri-food industry particularly food producer into this important business sector. The blockchain in its guise as distributed ledger’s allow encrypted information regarding each transaction to be securely shared between the relevant parties and offers a new approach for enhancing transparency and traceability between business and food producer, as well as the government organisations. This paper introduces the challenges currently faced by food producers and demonstrates how blockchain could potentially integration and improve service reliability for food producers.

Abstract The increasing population and income inequality in the last decades have made it necessary to focus on the concept of sustainability. In the changing world order, with economic crises, instabilities, pandemics, and social media, sustainability awareness differs significantly from past years. In addition, developing new technologies and concepts (big data, blockchain, IoT, robotic, etc.) plays a crucial role in meeting social awareness in terms of sustainability. Food sustainability is also one of the most important pillars in this concept. The integration of new technologies in agriculture and food chains will enable the current world population to use resources more efficiently and sustainably. Blockchain, one of the technologies that emerged with the arrival of Industry 4.0, is a technology that can be used effectively in many sectors. Particularly in supply chain networks, it is seen as a technology that supports the sustainability concept due to its features such as decentralization, reliability, transparency, consensus standards, and traceability. However, since blockchain is an immature and new technology, there are some challenges with integrating it into existing conventional systems. This study aims to present a conceptual framework for the integration of blockchain technology to establish a sustainable tea supply chain, define possible actions, and prioritize the possible risks that may arise in this integration process; this will be done through the Spherical Fuzzy Analytic Hierarchy Process (SF‐AHP) approach. In this context, initially, the current tea supply chain will be considered and the activities carried out will be defined in terms of technological, environmental, and strategic sustainability. Then, the design that includes the integration of all activities with blockchain technology is presented. The proposed design covers the entire tea supply chain from end to end and is considered with regard to all sustainability dimensions. In the proposed framework, barriers that may be encountered and risks that may arise at each stage of the tea supply chain process are identified; managerial implications are then presented to eliminate these risks. To enhance the use of the recommendations made, risks and barriers are prioritized with SF‐AHP management. Thus, the problems that need to be solved primarily in the technological transformation process can be evaluated more clearly. The proposed theoretical framework is expected to extend to all agricultural practices and support technological advances throughout the agricultural sector.

Modern supply chain management relies heavily on crop processing technologies and blockchain technology. However, the majority of crop processing technology fails due to a lack of available supply chain management technologies. A supply chain management system based on crop processing is developed in this research. Digital ledger technology (blockchain) takes care of supply chains and deep learning image processing (crop processing). To process the harvested crops, the study makes use of machine learning techniques. Blockchain supply chain management technology is then used to deliver the processed crops to the shops. Consequently, the research permits the accurate and transparent distribution of crops to users in an optimal and secure manner. The full hybrid model is tested in a simulation to see if it can improve agricultural production and supply chain management. This new strategy improves agricultural processing rates, and when combined with the blockchain distributed ledger technology, this results in optimal crop management for the required users.

Agriculture traceability demands a large volume of data that needs to be collected across the supply chain. Very early tracking and traceability systems used workers to record the information manually which entails risks, such as faulty information recording as well as inefficient resource usage. The implementation of tamper proof semi-automated digital ledgers will have a great impact on issues such as compliance with regulations, food provenance, food fraud, and many others, and therefore will gradually increase the trust within the supply chain. This paper provides an overview on the different stages of the AgriFood supply chain and of the fundamentals of a Distributed Ledger Technology, namely Blockchain, which can be used to mitigate some of the issues related to transparency and traceability of this sector. It also presents some solutions that already implement this technology to enable the traceability in the AgriFood sector. The authors also present the most important challenges and opportunities identify regarding the application of Blockchain based traceability systems for the AgriFood supply chain.

Abstract Food supply chain transparency and traceability is very important to address the issue regarding quality and safety. In traditional tracing system, with increasing the complexity of supply chain making product recalls difficult to manage and putting human lives at risk. To eliminate such types of risks, blockchain technology gives more efficient and reliable system for food tracing. Recently, there is an exponential rise in adoption of blockchain technology and most disparate IOT (Internet of things) devices in agriculture and food supply chain. It is an evolving technology that comforts the food supply chains by providing transparent data records and manage the food movement in the chain using distributed (P2P) network. That is more secured and there's no need for third party verifications. Our focus in this research will be on the Indian wheat supply chain and issues related to food losses caused by a lack of transparency and traceability. In order to improve the transparency of the wheat supply chain, we created an end-to-end smart wheat supply chain solution that combines blockchain technology, NFC tags, IoTs, and smart contracts. The solution is supported by entity relationship diagrams, information and money flow sequence diagrams, and a blockchain network diagram. We also used a security algorithm and the “NFC-Tag writer by NXP” program to validate and assess our system. This work could serve as a springboard for more in-depth research in this area. Depending on the existing situation in the industry, this research can also advise corporate procedures to deploy blockchain-based applications in the supply chain and logistics industry.

Recent progress in IoT and software development has simplified data acquisition and immutability of information in the agri-food supply chain. In the last few years, several frameworks and applications were proposed to ensure traceability in the agri-food-sector using distributed ledger technologies (DLT) such as Blockchain technologies. Still, no other study has presented a Blockchain-based traceability platform with a lower impact on the environment and lower cost for each transaction sent by the supply chain. This article presents a traceability platform based on Green Blockchain with low energy consumption and costs savings applied to the Fontina PDO cheese supply chain, part of the project “Typicalp”, funded by the European Union (EU). The proposed traceability system is based on Algorand Blockchain, which uses the Pure Proof-of-Stake mechanism of consensus that requires minimal computational power, is highly scalable and environmentally sustainable. In addition to the environmental and financial benefits, the developed traceability platform has made it possible to digitize the entire production chain, making the data immutable and available in real-time for Fontina consortium operators and final consumers.

Purpose This study aims to formulate a conceptual sustainable framework for developing a trusted, reliable, scalable, transparent, traceable and sustainable agri-food supply chain in a developing country so that it minimizes wastage and increases the efficiency levels of agri-produce and its usage. Design/methodology/approach This study uses a rigorous review of extant literature, case studies and the interview method for theory building, using blockchain technology (BT) as a subject. Further, the study builds a framework to relate blockchain solutions to the challenges faced by the agri-supply chain. Notably, the use of BT in the agri-food supply chain is a relatively new area of study. Findings Limitations of using BT 3.0 in a diverse supply chain like the food sector, especially in a developing country such as India, may be overcome by adopting BT 4.0 and could change the country’s face by controlling inefficiencies and ensuring transparency, helping in good governance, improving the humanitarian supply chain and integrating the bottom of the pyramid to the main economy. Based on the findings, this study proposes BT 4.0 for the agri-supply chain in India to deal with the current issues of demand-supply gap, wastages of agri-produce, unequal distribution of profit among agriproduct producers and logistics suppliers and ensuring sustainability. Research limitations/implications Results in this study have been derived from a specific demographic condition in India. Future research with other demographic conditions may be replicated. BT is a new technology product, and its effectiveness is yet to be established. Practical implications The outcome of this study provides the application of BT 4.0 in the area of the agri-food supply chain. The BT 4.0 framework has been developed on studying a few cases that either implemented BT or were in the testing phase. The benefits of the agri-food supply chain vis-à-vis its overall social well-being may be achieved on the successful implementation of the framework, despite existing complexities in the food supply chain. Further research on this subject may help the other dimensions of the complexity of adopting BT 4.0. Both practitioners and policymakers from developing countries can, therefore, use the findings of this study to analyze BT 4.0 and address the concerns of the agri-food supply chain. Originality/value This research paper has proposed a conceptual framework of BT 4.0, which is a completely new technology. It is fairly transparent, and therefore sustainable supply chain practices may be achieved easily.

Tracing food products along the entire supply chain is important for achieving better management of food products. Traditionally, centralized traceability systems have been developed for such purposes. One major drawback of this approach is that different users of the supply chain have their own systems with their own complexities and distinct features; thus, the interaction among them creates challenges when implementing a single centralized system. Therefore, a decentralized traceability system is favorable for tracing food products along the supply chain. In this study, we develop a supply chain traceability system framework based on blockchain and radio frequency identification (RFID) technology. The system consists of a decentralized blockchain-enabled data storage platform for data management and an RFID system at the packaging level for data collection and storage. We applied a consortium blockchain to the application. Fabric 2.0 in Hyperledger was chosen as the development platform. The proposed blockchain-enabled platform can provide decentralized data management and its underlying algorithm can guarantee data security. The system includes a creatively designed blockchain-enabled data structure in the RFID tag. When people scan the tag, the relevant information is written in the tag as a block linked to the previous blocks; simultaneously, the information is transmitted to the blockchain platform and recorded on the platform. No battery is required and the system works when there is an RFID reader nearby. The usage conditions included shipment, stocking, and storage. The RFID tag can be directly attached to paper packaging. This approach embeds the blockchain technique into the RFID tag and develops a corresponding system. The new traceability system has the potential to simplify the tracking of products and can be scaled for industrial use.

Smallholder farmers produce over 70% of the world’s food needs. Yet, the socioeconomic conditions of the smallholder farmers are substandard. One of the primary reasons for this unpropitious situation is that they generate modest income by selling their harvest due to the lack of trusted buyers and organized markets. This research explores how technology can enable the trust to reduce transaction-related risks, empowering unknown parties to transact. Blockchain technology has the potential of mitigating transaction-related risks and promoting trust with a tamper-proof history of transactions and automatic execution of smart contracts. Based on blockchain technology to promote trust, this research has discovered a novel approach for smallholder farmers to conduct exchanges by generating social capital as an individual and using that social capital as collateral for financial exchanges when establishing contracts. This approach empowers farmers to trade smart futures contracts on behalf of the expected harvest at a better rate to receive some cash in advance to be used in the cultivation process to produce a high-quality harvest that attracts better rates. It also enables them to perform aggregated marketing with enhanced market linkages that, in turn, assist in increasing margins made by the farmer.

In agriculture supply chain management, traceability is a crucial aspect to ensure food safety for increasing customer loyalty and satisfaction. Lack of quality assurance in centralized data storage makes us move towards a new approach based on a decentralized system in which transparency and quality assurance is guaranteed throughout the supply chain from producer to consumer. The current supply chain model has some disadvantages like a communication gap between the entities of the supply chain and no information about the travel history and origin of the product. The use of technology improves the communication and relation between various farmers and stakeholders. Blockchain technology acquires transparency and traceability in the supply chain, provides transaction records traceability, and enhances security for the whole supply chain. In this paper, we present a blockchain-based, fully decentralized traceability model that ensures the integrity and transparency of the system. This new model eliminated most of the disadvantages of the traditional supply chain. For the coordination of all transactions in the supply chain, we proposed a decentralized supply chain model along with a smart contract.
