“…Various initiatives have been implemented to enhance the scalability and security of blockchain, DLT and IoT solutions, ensuring the food safety in FSCs [61,72], such as sharding, novel smart contract mechanisms, distributed and off-chain data storage solutions and platforms, such as IPFS and BigchainDB, to store large amounts of data from various origins, including sensor data. Various data access and data manipulation rights have been introduced with various encryption algorithms, such as ZKP [58], homomorphic encryption or attribute-based encryption, to improve the aspects of security, privacy and confidentiality in such applications.…”

The lack of transparency and traceability in food supply chains (FSCs) is raising concerns among consumers and stakeholders about food information credibility, food quality, and safety. Insufficient records, a lack of digitalization and standardization of processes, and information exchange are some of the most critical challenges, which can be tackled with disruptive technologies, such as the Internet of Things (IoT), blockchain, and distributed ledger technologies (DLTs). Studies provide evidence that novel technological and sustainable practices in FSCs are necessary. This paper aims to describe current practical applications of DLTs and IoT in FSCs, investigating the challenges of implementation, and potentials for future research directions, thus contributing to achievement of the United Nations’ Sustainable Development Goals (SDGs). Within a systematic literature review, the content of 69 academic publications was analyzed, describing aspects of implementation and measures to address the challenges of scalability, security, and privacy of DLT, and IoT solutions. The challenges of high costs, standardization, regulation, interoperability, and energy consumption of DLT solutions were also classified as highly relevant, but were not widely addressed in literature. The application of DLTs in FSCs can potentially contribute to 6 strategic SDGs, providing synergies and possibilities for more sustainable, traceable, and transparent FSCs.

“…Another common architectural scheme in creating decentralized applications is to store hashes in the blockchain and actual data in external storage. Most architectures use IPFS to store agriculture data and the blockchain stores either the IPFS hash [72][73][74][75][76][77][78][79] or the data hash [58,59,80]. There is a study [58] that stores data from sensors in IPFS, then the hash of this data is stored in a private permissioned blockchain, while the block hash of this blockchain and the height of the block are stored in Ethereum.…”

“…This happens at 61% and 50%, respectively. Moreover, few papers (3%) [57,72,99] use another intrinsic feature of blockchain technology: its data availability. It should be mentioned that many solutions involve the use of blockchain over conventional databases due to the availability provided but do not clearly define it, so it has not been included in our respective count.…”

“…Blockchain provides a permanent record for each transaction segment, which is grouped into separate blocks and cannot be tampered with [26]. Through the blockchain, all agricultural product information can be stored in a system that is shared and transparent to all members of the supply chain [27], instead of being stored in an opaque network system [28,29], which helps prevent the excessive use of chemicals and the use of uncertified chemicals in the production process [30]. Therefore, rapid response and efficient control of agricultural product quality problems are realized, and food safety and consumer health are ensured [31][32][33].…”

In recent years, with the frequent crises of trust in the food industry, food safety issues have become an issue of particular concern to consumers. The traditional agricultural food logistics and transportation model can no longer guarantee the traceability of food safety information, and it is particularly important to establish an effective traceability system. Therefore, a traceability system is applied as a tool to assist in the assurance of food safety and quality, as well as to achieve consumer confidence. Blockchain is a new decentralized infrastructure and distributed computing paradigm that has gradually emerged. Blockchain has the characteristics of decentralization, immutable information and trustworthiness. When blockchain is applied to the traceability system of agricultural products, the quality of agricultural products will be well guaranteed. This article aims to provide a comprehensive review of the recent research efforts on traceability in agricultural products based on blockchain technology. First, the method of content analysis used in this article to sort out the papers is introduced. Second, the background concepts of blockchain and the key technologies are presented. Thirdly, the traceability applications based on blockchain technology for agricultural products are described in detail. Finally, we expand on the current trends and provide new perspectives pertaining to this exciting application of this field.
