Abstract Applications of blockchain in the food sector are growing and the adoption of farm‐to‐fork traceability systems is at the forefront. We review applications of blockchain across different dimensions while focusing on how broad adoption of the technology might help address major challenges faced by the U.S. fresh produce industry. These challenges include food safety, food fraud, food loss and waste, and the general need for better traceability systems. We discuss whether blockchain technologies might play a role in enhancing the resilience of the produce supply chain and highlight limitations and challenges of the technology stakeholders might consider going forward.

<abstract> This study investigates the attitudes and perceptions of businesses and consumers towards the application of Blockchain technology (BCT) to fresh produce supply chains. Semi-structured interviews and focus groups (FG) were performed with fresh produce company managers and consumers, respectively. The fresh produce sector, in this context, concerns the fresh and chill chain, value-added vegetables, fruits and salads and the ingredients of these used in further food value-added processes and products. A total of five themes were identified as factors influencing BCT adoption: the novelty of the technology, supply chain characteristics, open data issues, cost-benefit analysis, and role of public stakeholders. From these, twelve sub-themes were developed and discussed. Findings provide a framework with opportunities and challenges that the fresh produce system must face in adopting decentralised systems for managing supply chain data like BCT. </abstract>

The use of new technologies to empower the social co-governance of food safety is a consensus in the theoretical and practical fields of food safety governance modernization. Based on the innovative features of the block chain such as non-tampering, consensus mechanism, and a smart contract, this paper proposes a new method to facilitate the achievement of the effect of social co-governance of food safety. Firstly, it provides a profound analysis of the causes of food safety problems and the drawbacks of traditional centralized supervision, and proposes a solution with decentralized features and the design process of smart contracts to realize the chaining and integration of finite credible data in the process of food circulation; secondly, it constructs a mathematical model through finite credible data on the chain and obtains the probabilistic consensus results of food safety through rigorous derivation; Finally, the scheme, model and algorithm are effectively practiced through the experimental environment of mature block chain platform and provincial food supervision platform. The example shows that the market failure problem in food safety can be greatly alleviated by the non-tampering feature of block chain; the consensus results formed by the credible data uploading, model construction and data derivation through smart contracts can greatly alleviate the problem of involution of government administrative supervision; and the social co-governance capacity of food safety can be improved through information sharing with the active synergy of multiple subjects of co-governance.
Supply chain management, product provenance and quality certification are among the first and most popular applications of blockchain technology, due to the inherent trust and inalterability provided by the blockchain technology. However, the proposed supply chain management systems based on blockchain and smart contract technology tend to be specific to the particular production and production process. In this paper we present a general-purpose approach for the agri-food supply chain management, proposing a system that can be configured for most agri-food productions. The primary purpose is to provide a methodology to facilitate and make more efficient the development of such applications. It is based on general smart contracts and apps interacting with the same smart contracts, which are configured, starting from the description of the specific system to be managed, given using json files. A case study on olive oil production is described, to show how our approach works.
Blockchain technology is a secure distributed ledger for lists of transactions, which has immense potential to solve traditional agri-food supply chain issues. An increasing number of research on blockchain-based traceability applications aims to improve food quality and safety. Still, relatively few works considered user interfaces when developing and reporting their applications, which could lead to usability issues. This paper aims to address this gap by reviewing existing works from user interface perspectives. We gathered 25 review papers on blockchain or agri-food supply chain and 39 research papers that presented screenshots of user interfaces of related applications. We first reviewed 7 review papers that focused on the blockchain-based agri-food supply chain to understand the benefits and challenges in the blockchain applications. We then analyzed 14 blockchain-based agri-food traceability applications and 10 non-blockchain-based agri-food traceability applications. The analysis resulted in categorizations of 5 target user groups, 3 main approaches for collecting data, 5 main approaches for visualizing data, and a discussion of other aspects of user interfaces. However, we found insufficient details and discussions on the user interfaces and design decisions of the applications for further usability assessment. Additionally, user involvement for evaluation is lower in blockchain-based researches than in non-blockchain-based researches. This trend could lead to usability problems of blockchain applications, causing blockchain technology to be underutilized. Finally, we discussed research gaps and future research directions related to user interface design, which should be addressed to ease future blockchain adoption.
In this paper we present a blockchain based system for the supply chain management of a particular Italian bread. Goal of the system is to guarantee a transparent and auditable traceability of the Carasau bread where each actor of the supply chain can verify the quality of the products and the conformity to the normative about the hygienic-sanitary conditions along the chain. To realize this system we relied on the Blockchain and the Internet of Thing technologies in order to provide a trustless environment, in which trust is placed in cryptography, in mathematical operations and on the network, and not in public or private companies. Thanks to the use of digital technologies the system aims to reduce the data entry errors and the risk of tampering. Our system is designed so that along the supply chain, the nodes equipped with several sensors directly communicate their data to Raspberry Pi units that elaborate and transmit them to Interplanetary File System and to the Ethereum Blockchain. Furthermore, we designed ad hoc Radio Frequency Identification and Near Field communication tags to shortly supply the proposed system with information about the products and batches. The dedicated RFID tags robustness during on-bread operation was numerically tested. The system will easily allow end consumers to have a transparent view on the whole journey from raw material to purchased final product and a supervisory authority to perform online inspections on the products’ quality and on the good working practices.
In agri-food supply chains (ASCs), consumers pay for agri-food products produced by farmers. During this process, consumers emphasize the importance of agri-food safety while farmers expect to increase their profits. Due to the complexity and dynamics of ASCs, the effective traceability and management for agri-food products face huge challenges. However, most of the existing solutions cannot well meet the requirements of traceability and management in ASCs. To address these challenges, we first design a blockchain-based ASC framework to provide product traceability, which guarantees decentralized security for the agri-food tracing data in ASCs. Next, a Deep Reinforcement learning based Supply Chain Management (DR-SCM) method is proposed to make effective decisions on the production and storage of agri-food products for profit optimization. The extensive simulation experiments are conducted to demonstrate the effectiveness of the proposed blockchain-based framework and the DR-SCM method under different ASC environments. The results show that reliable product traceability is well guaranteed by using the proposed blockchain-based ASC framework. Moreover, the DR-SCM can achieve higher product profits than heuristic and Q-learning methods.
Traditional traceability system has problems of centralized management, opaque information, untrustworthy data, and easy generation of information islands. To solve the above problems, this paper designs a traceability system based on blockchain technology for storage and query of product information in supply chain of agricultural products. Leveraging the characteristics of decentralization, tamper-proof and traceability of blockchain technology, the transparency and credibility of traceability information increased. A dual storage structure of “database + blockchain” on-chain and off-chain traceability information is constructed to reduce load pressure of the chain and realize efficient information query. Blockchain technology combined with cryptography is proposed to realize the safe sharing of private information in the blockchain network. In addition, we design a reputation-based smart contract to incentivize network nodes to upload traceability data. Furthermore, we provide performance analysis and practical application, the results show that our system improves the query efficiency and the security of private information, guarantees the authenticity and reliability of data in supply chain management, and meets actual application requirements.

The complexity of a supply chain makes product safety or quality issues extremely difficult to track, especially for the basic agricultural food supply chains of people's daily diets. The existing agricultural food supply chains present several major problems, such as numerous participants, inconvenient communication caused by long supply chain cycles, data distrust between participants and the centralized system. The emergence of blockchain technology effectively solves the pain-point problem existing in the traceability system of agricultural food supply chains. This paper proposes a framework based on the consortium and smart contracts to track and trace the workflow of agricultural food supply chains, implement traceability and shareability of supply chains, and break down the information islands between enterprises as much as possible to eliminate the need for the central institutions and agencies and improve the integrity of the transaction records, reliability and security. At the same time, farmers record details of the environment and crop growth data in the InterPlanetary File System (IPFS) and store file IPFS hashes in smart contracts, which not only increases data security but also alleviates the blockchain storage explosion problem. This framework has been applied in Shanwei Lvfengyuan Modern Agricultural Development Co., Ltd. Although there are still many defects, the framework has successfully realized functions such as disintermediation and tracing of agricultural product information through QR codes. Thus, the framework proposed in this paper is of great significance and reference value for enterprises to ensure product quality and safety traceability.
With the development of Internet technology, especially the application of mobile Internet technology in people’s daily lives, people’s lifestyles and production methods have changed, and they have brought huge economic benefits to society. In order to improve the development quality of agricultural e-commerce and expand the integration model of e-commerce, the paper analyzes the development and changes of Internet technology in the agricultural industry chain from the source to operation, production, service, security, and sales and studies the production experience model iterative upgrade. At the same time, a blockchain-based agricultural product traceability system is proposed. The system has a good supervision effect. Once recorded on the blockchain ledger, all data cannot be changed, which plays a very good traceability role for agricultural e-commerce. Actual cases show that the integrated model of agricultural e-commerce based on blockchain technology can bring huge development potential to the e-commerce industry and can improve the security and traceability of agricultural e-commerce.
One of the essential points of food manufacturing in the industry and shelf life of the products is to improve the food traceability system. In recent years, the food traceability mechanism has become one of the emerging blockchain applications in order to improve the anti-counterfeiting area’s quality. Many food manufacturing systems have a low level of readability, scalability, and data accuracy. Similarly, this process is complicated in the supply chain and needs a lot of time for processing. The blockchain system creates a new ontology in the traceability system supply chain to deal with these issues. In this paper, a blockchain machine learning-based food traceability system (BMLFTS) is proposed in order to combine the new extension in blockchain, Machine Learning technology (ML), and fuzzy logic traceability system that is based on the shelf life management system for manipulating perishable food. The blockchain technology in the proposed system has been developed in order to address light-weight, evaporation, warehouse transactions, or shipping time. The blockchain data flow is designed to show the extension of ML at the level of food traceability. Finally, reliable and accurate data are used in a supply chain to improve shelf life.

Abstract Amid stringent traceability requirements and a nearly 14‐year ban, the U.S. beef industry is rebuilding its market presence in China. Blockchain technology offers a responsive means of meeting Chinese import traceability requirements while also addressing consumers' food safety concerns. We evaluate Chinese demand for U.S. beef and blockchain‐based traceability and find that a sizeable segment of the market (37%) is willing to pay a premium for U.S. beef that is traceable using blockchains. Results indicate that investments in traceability systems that utilize blockchain technology may be an effective way for producers to capture a significant market share in China.
In this modern era, as the demand for the products has substantially increased, it has been observed that compromises being made in the quality of the products. This has also led to many frauds due to the lack of transparency in the Supply Chain Management (SCM) systems. Due to the inconsistency and opaqueness of these systems, it is not possible to detect all the fraudulent steps that have been carried out with the product and other compromises that have been made to the quality of the product.Here we propose a blockchain-based product traceability system to overcome these inconsistencies in the current systems. With the help of enhanced security of blockchain technology [1], tampering of the data can be prevented and transparency of this system can help us develop and maintain trust among all the participating entities in the system. In this way, we can eradicate all the discrepancies present in the current system and ensure that the quality of the product is not being compromised.

Considering the overall situations of cultivator’s economic degradation, food safety chain issue, and whole food supply chain, newer technologies are emerging in the field of agriculture over time. If we look at third world countries, these traditional food supply chains still play the main bearish down prediction. For the result, if any customer deceived by adulterated foods, then in most cases, he/she could not get the original source of the food where it was produced or processed. And in this case, also the administration cannot make this possible to identify and punish the fraudsters. This is where the fraudsters get the opportunity to mix adulteration in foods, put new expiration on expired foods, and release them in the market. Again because of the lack of efficient distribution facilities between cultivators and industrial or last stage vendors, most of the cases cultivators could not get fair pay. And to solve this problem and set explicit or trustworthy communications, the civilization needed immutable and trustworthy technology so that all these problems can be solved. And in that stage, blockchain comes to the picture. In this research paper, we propose an effective, efficient, and satisfactory model or system and service solution to agro traders and also a food traceability system based on blockchain and the help of IoT to make their business more smart and rich. And through the blockchain, smart contract, and the help of IoT sensors, we tried to do maximum effort to reduce human intervention.
