The Effect of Blockchain Technology in Enhancing Ethical Sourcing and Supply Chain Transparency: Evidence from The Cocoa and Agricultural Sectors in Ghana

This study examines the impact of blockchain technology on ethical sourcing and supply chain transparency in Ghana's cocoa and agriculture industries. Using the Diffusion of Innovation Theory as a framework, the study investigates the adoption and influence of blockchain technology on ethical sourcing practices and supply chain transparency. Regression analysis was conducted using data from 153 firms in the agricultural and cocoa sectors to explore the relationships between blockchain technology usage, ethical sourcing, supply chain transparency, adoption of new technologies, and corporate social responsibility. The results highlight the significant influence of blockchain technology adoption on supply chain transparency and ethical sourcing practices in the cocoa and agricultural sectors. Specifically, companies that utilize blockchain technology tend to have more transparent supply chains and are more likely to engage in ethical sourcing compared to those that do not. Moreover, there is evidence suggesting that the use of technology, particularly blockchain, is a strong predictor of increased transparency, with positive correlations observed across all industries. These findings illustrate the potential of blockchain technology to enhance ethical sourcing methods and supply chain transparency in Ghana's cocoa and agriculture industries. It is recommended that both public and private corporations consider investing in technology adoption, particularly blockchain technology, as it has the potential to improve ethical sourcing practices.

Securi-Chain: Enhancing Smart Contract Security in Blockchain Systems Through Optimized Access Control

With the increase in usage of blockchain technology across domains, there is a high demand for the need of secure access control and a high level of security for smart contracts within blockchain to accommodate the domains that already implement blockchain and become accessible to other domains that require a high level of security in its transactions. This paper aims to evaluate the relationship between the best practices of access control and security of smart contracts in blockchain to optimise the usage of both technologies for blockchain usage across domains into a generalized blockchain model named the Securi-Chain Model. A literature review compares the relationship between access control and the security of smart contracts across three domains: Healthcare, IoT, and e-voting. Based on the findings of the literature review, Securi-Chain is proposed to implement the best practices displayed in these three domains and combine them in a way that ensures secure transactions across blockchain as a generalized approach that can be used throughout various domains. This model will also implement methods that enhance the security of transaction processes within the system. A Case Scenario is used to implement the Securi-Chain Model for the Healthcare and e-voting domains to display how this proposed model is used for domains that have been researched. The research that is conducted found that blockchain networks can support not only high-level access control across transactions in a network but also the security of smart contracts that comply to safeguard confidentiality, integrity, and data accessibility. Secrui-Chain, as well as the findings of the literature review, seem to benefit the domains that have been researched, as well as domains that require a high level of security regarding transactions across a network. These domains can benefit from using blockchain technology as well as the level of security that comes with the access control and security of smart contracts that have been implemented in Securi-Chain.

Blockchain-driven incentive mechanism for agricultural water-saving: A tripartite game model

Implementing water-saving agriculture is an important measure to alleviate water resource shortage, improve agricultural ecological environment, and achieve sustainable agricultural development. However, both water-saving service companies (WSSCs) and farmers often lack the motivation to adopt water-saving practices due to the high implementation costs involved. To overcome this shortcoming, this study aims to design a blockchain-driven incentive mechanism based on the evolutionary game theory, in which the government, WSSCs and farmers are game subjects and the idea of cooperative incentive for the government is introduced. Through analyzing the complex interactions among various stakeholders and agricultural water-saving incentives, some findings of this study are obtained. Firstly, the usage of blockchain technology (BT) in the incentive mechanism for agricultural water-saving is reflected in supervision and additional default costs, which promote the sustainable cooperation among government, WSSCs and farmers in varying degrees. Secondly, the additional default costs brought by the usage of BT have a deterrent effect on WSSCs and farmers, which makes them to actively implement water-saving practices. Thirdly, the additional default cost brought by BT has become the main basis for the government to choose BT supervision. As the additional default cost increases, the government are not more inclined to use BT. It provides valuable insights into motivating diverse stakeholders to actively participate in water-saving practices, promoting sustainable water resources management in agriculture.

Dynamic Evolutionary Game Approach for Blockchain-Driven Incentive and Restraint Mechanism in Supply Chain Financing

The sustainability of financing is an important measure in the development of supply chains. However, the difficulty and high cost of financing have always been critical factors hindering the sustainable development of small and medium-sized enterprises (SMEs). Blockchain technology (BT) is an effective tool to relieve the current problem. Based on it, this study aims to establish Blockchain-driven incentives and restraint mechanisms for SME financing using a dynamic game model in which financial institutions (FIs) and new agricultural business entities (NABEs) are regarded as game subjects. By analyzing the impact of key parameters on the equilibrium state of the game for all stakeholders, several findings are drawn as follows. (1) The usage of BT affects FI loan strategies by influencing their cost in supply chain financing. (2) The usage of BT affects NABE’s strategy choice by influencing their loan interest rate. (3) The usage of BT affects NABE’s strategy choice by influencing their default losses. (4) The usage of BT affects NABE’s and FI’s strategy choices by influencing their additional benefits. This study provides decision-making support for optimal strategy decisions under different conditions and serves as a theoretical reference for the government in formulating financing incentive and restraint mechanisms.

Graph-Based Profiling of Blockchain Oracles

The usage of blockchain technology has been significantly expanded with smart contracts and blockchain <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oracles</i> . While smart contracts enables to automate the execution of an agreement between untrusted parties, oracles provide smart contracts with data external to a given blockchain, i.e., off-chain data. However, the validity and accuracy of such off-chain data can be questionable that compromises the transparency and immutability chacteristics of blockchain. Despite many studies on the trustworthiness of blockchain oracles, more precisely, off-chain data, their solutions are often ‘short-sighted’ and dependent on binary decisions. In this paper, we present a novel graph-based profiling method to determine the trustworthiness of blockchain oracles. We construct a graph with oracles as nodes and cumulative average discrepancies of validity and accuracy of data as edge weights. Our profiling method continues to update the graph, edge weights in particular, to distinguish trustworthy oracles. Clearly. this discourages the provision of false and inaccurate data. We have conducted an evaluation study to see the effectiveness of our proposed method, in which we have run the experiments utilizing the Ethereum network. Additionally, we have also calculated the cost of running these experiments. Consequently, our experiment results show that the proposed method achieves around 93% accuracy in identifying the trustworthiness of data sources.
