Modeling the blockchain enabled traceability in agriculture supply chain
Abstract Blockchain Technology (BT) has led to a disruption in the supply chain by removing the trust related issues. Studies are being conducted worldwide to leverage the benefits provided by BT in improving the performance of the supply chains. The literature reveals BT to offer various benefits leading to improvements in the sustainable performance of the agriculture supply chains (ASC) It is expected that BT will bring a paradigm shift in the way the transactions are carried in the ASC by reducing the high number of intermediaries, delayed payments and high transaction lead times. India, a developing economy, caters to the food security needs of an ever growing population and faces many challenges affecting ASC sustainability. It is therefore essential to adopt BT in the ASC to leverage the various benefits. In this study, we identify and establish the relationships between the enablers of BT adoption in ASC. Thirteen enablers were identified from the literature and validated by the experts before applying a combined Interpretive Structural Modelling (ISM) and Decision Making Trial and Evaluation Laboratory (DEMATEL) methodology to envision the complex causal relationships between the identified BT enablers. The findings from the study suggest that, among the identified enablers, traceability was the most significant reason for BT implementation in ASC followed by auditability, immutability, and provenance. The findings of the study will help the practitioners to design the strategies for BT implementation in agriculture, creating a real time data driven ASC. The results will also help the policymakers in developing policies for faster implementation of BT ensuring food safety and sustainable ASCs.

Blockchain Based Agri Food Supply Chain: A Complete Solution
Supply chains are evolving into automated and highly complex networks and are becoming an important source of potential benefits in the modern world. At the same time, consumers are now more interested in food product quality. However, it is challenging to track the provenance of data and maintain its traceability throughout the supply chain network. The traditional supply chains are centralized and they depend on a third party for trading. These centralized systems lack transparency, accountability and auditability. In our proposed solution, we have presented a complete solution for blockchain based Agriculture and Food (Agri Food) supply chain. It leverages the key features of blockchain and smart contracts, deployed over ethereum blockchain network. Although blockchain provides immutability of data and records in the network, it still fails to solve some major problems in supply chain management like credibility of the involved entities, accountability of the trading process and traceability of the products. Therefore, there is a need of a reliable system that ensures traceability, trust and delivery mechanism in Agri Food supply chain. In the proposed system, all transactions are written to blockchain which ultimately uploads the data to Interplanetary File Storage System (IPFS) The storage system returns a hash of the data which is stored on blockchain and ensures efficient, secure and reliable solution. Our system provides smart contracts along with their algorithms to show interaction of entities in the system. Furthermore, simulations and evaluation of smart contracts along with the security and vulnerability analyses are also presented in this work.

Sea Food Supply Chain Management Using Blockchain
Blockchain is a distributed open ledger that is used to record the transaction across many computers. Blockchain technology can be applied in any domain such as banking, healthcare, real estate, travel, food, and supply chain. Blockchain allows us to have a distributed peer to peer networks, so it provides security and privacy. Example: Bitcoin. To enhance the Supply chain management using in the blockchain using some unique tags (Example: RFID/NFC/QR Code) tags describe the information about products and track the products. This paper discusses the blockchain in supply chain management to eliminate the disadvantages of the supply chain in the life cycle. In order to provide the solution of supply chain management to using these unique tags to get all details for manufacturing date/expiry date, etc. from the manufacturer side so no can alter this tag for the manufacturer to build a trustworthy of wholesaler/retailer/consumer for using the special tags.

A Content Analysis Based Literature Review in Blockchain Adoption within Food Supply Chain
According to the World Health Organization (WHO) one out of 10 people get sick from eating contaminated food. Complex food production process and globalization make food supply chain more delicate. Many technologies have been investigated in recent years to address food insecurity and achieve efficiency in dealing with food recalls. One of the most promising technologies is Blockchain, which has already been used successfully in financial aspects, such as bitcoin, and it is attracting interests from food supply chain organizations. As blockchain has characteristics, such as decentralization, security, immutability, smart contract, it is therefore expected to improve sustainable food supply chain management and food traceability. This paper applies a content analysis based literature review in blockchain adoption within food supply chain. We propose four benefits. Blockchain can help to improve food traceability, information transparency, and recall efficiency; it can also be combined with Internet of things (IoT) to achieve better efficiency. We also propose five potential challenges, including lack of deeper understanding of blockchain, technology difficulties, raw data manipulation, difficulties of getting all stakeholders on board, and the deficiency of regulations.

Application of Blockchain in Agri Food Supply Chain
Supply chain traceability is one of the most important problems faced by all organizations globally. Tracking any commodity is a tedious job and requires a lot of manual attention. The existing system uses a centralised database system to track a commodity. Blockchain is a decentralised, immutable ledger managed by a cluster of computers. The very nature of blockchain makes it suitable technology for traceability in a supply chain. Blockchain creates immutable records. Once a transaction is stored in the blockchain, it is impossible to tamper it illegally. This immutability of blockchain builds trust among the participants that conduct business in a lack of trust environment. Using consensus protocols, blockchain builds trust between the various participants. Blockchain provides traceability since immutable records are added in blockchain; it is easy to track the source of the product. This paper illustrates the Application of Blockchain in Agri Food Supply Chain. It unfolds how blockchain technology can be integrated to an Agri Supply Chain and improves the traceability. This integration enables companies to quickly track unsafe products back to their source and see where else they have been distributed. This integration can result to prevent illness and save lives, as well as reduce the cost of product recalls.

Blockchain Inspired RFID Based Information Architecture for Food Supply Chain
In this paper, we propose a blockchain inspired Internet of Things architecture for creating a transparent food supply chain. The architecture uses a proof of object based authentication protocol, which is analogous to the cryptocurrency's proof of work protocol. The complete architecture was realized by integrating a radio frequency identification (RFID) based sensor at the physical layer and blockchain at the cyber layer. The RFID provides a unique identity of the product and the sensor data, which helps in real time quality monitoring. For this purpose, a small feature size 900 MHz RFID coupled sensor was fabricated and demonstrated for real time sensor data acquisition. The blockchain architecture aids in creating a tamper proof digital database of the food packages at each instance. A detailed security analysis was performed to investigate the vulnerability of the proposed architecture under different types of cyber attacks.

Boundary conditions for traceability in food supply chains using blockchain technology
Abstract Traceability of ingredients in food supply chains has become paramount in a world in which markets become global, heterogeneous, and complex and in which consumers expect a high level of quality. The food supply chain consists of many organizations having different interests and are often reluctant to share traceability information with each other. Blockchain has been advocated for improving traceability by providing trust. Yet, practice proved to be more stubborn. The goal of this paper is to identify boundary conditions for sharing assurance information to improve traceability. Four cases in the food supply chain have been investigated using a template analysis of 16 interviews. Eighteen boundary conditions categorized in business, regulation, quality and traceability categories have been identified. Some boundary conditions were found in all supply chains, whereas others were found to be supply chain specific. Standardization of traceability processes and interfaces, having a joint platform and independent governance were found to be key boundary conditions before blockchain can be used. Our findings imply that supply chain systems have first to be modified and organizational measures need to be taken to fulfill the boundary conditions, before blockchain can be used successfully.

Impact of Blockchain Adoption for Safe Food Supply Chain Management through System Dynamics Approach from Management Perspectives in Thailand
Today's food supply chain is incredibly complex and imposes enormous challenges across the Globe. Products are transported through multimodal transportation internationally, comprising of combination of ship, rail, truck and flight modes etc. The supply chain under multistage network poses more quality related issues. Hence, blockchain technology helps to enhance food safety and quality in the logistics process. This, when coupled with the existing traceability system can create more agile value chain and closer customer relationship across regions. Though, Thailand is a leading food exporter, it lacks in implementation of blockchain technology. The objective of this study is to analyse the impact of blockchain technology adoption for safe food supply chain management through System Dynamics (SD) approach from management perspectives in Thailand. The preliminary survey and discussion were carried out with the participants from food expert firms, and causal loop diagrams and stock and flow diagrams were developed and validated. The trade off, challenges and opportunities of applying block chain technology on the global food value supply chain has been discussed throughout the system dynamics model. The major contribution of this work is in providing insight into some of the main dimensions of block chain technology and its implications for global food value chain performance improvements.

Blockchain: case studies in food supply chain visibility
Purpose: This paper investigates how blockchain has moved beyond cryptocurrencies and is being deployed to enhance visibility and trust in supply chains; its limitations, and potential impact. Approach: Qualitative analysis undertaken via case studies drawn from food companies using semi structured interviews. Findings: Blockchain is demonstrated as an enabler of visibility in supply chains. Applications at scale are most likely for products where the end consumer is prepared to pay the premium currently required to fund the technology, e.g. baby food. Challenges remain in four areas: trust of the technology; human error and fraud at the boundaries; governance; consumer data access and willingness to pay. Research implications and limitations: The paper shows that blockchain can be utilised as part of a system generating visibility and trust in supply chains. Research directs academic attention to issues that remain to be addressed. The challenges pertaining to the technology itself we believe to be generalisable; those specific to the food industry may not hold elsewhere. Practical implications: From live case studies we provide empirical evidence that blockchain provides visibility of exchanges and reliable data in fully digitised supply chains. This provides provenance and guards against counterfeit goods. However, firms will need to work to gain consumer buy in for the technology following repeated past claims of trustworthiness. Originality: This paper provides primary evidence from blockchain use cases 'in the wild' The exploratory case studies examine application of blockchain for supply chain visibility.
