1. Blockchain technology implementation for traceability in the food supply chain – case research : XIII.Marina Balaic, Samo Bobek, Vujica Lazović, Simona Sternad Zabukovšek, 2025, independent scientific component part or a chapter in a monograph Abstract: Food supply chains are evolving into coordinated systems, prompting competition between companies and entire supply networks. In this context, Short Food Supply Chains (SFSCs) have emerged as a response to public concerns about food sourcing and handling. Defined by the EU as systems involving few economic actors committed to local development and close producer-consumer relations, SFSCs present both opportunities and challenges. Among key challenges are identity management, transparency, and security. Blockchain technology, introduced shortly after SFSCs gained attention, offers promising solutions by enhancing traceability and linking product information with physical flows. This chapter explores the role of blockchain in addressing traceability challenges and presents a practical case of its application in SFSCs.
Keywords: agribusiness supply chains, short food supply chains, traceability technologies, blockchain technology, implementing blockchain in the food supply chain

2. Analyzing supply chain dynamics to enhance their environmental performance in the age of emerging technologies : doctoral dissertationSamar Kamal Mohamed, 2024, doctoral dissertation Abstract: Amid the rapid increase in environmental degradation and the depletion of natural resources, there has been a noticeable shift in global focus from economic issues to environmental concerns. The research conducted for the doctoral dissertation addresses the complexity of building supply chain resilience (hereafter: SCR) for long-term environmental sustainability. It examines the potential of new technologies, particularly blockchain technology (hereafter: BCT), as an innovative tool for enhancing the sustainability and resilience of supply chains, with a focus on uncertain environments. Utilizing Systems Theory (hereafter: ST) and the Knowledge-Based View (hereafter: KBV), this study aims to demonstrate how BCT adoption can improve environmental supply chain performance (hereafter: ESCP).
Empirical testing was conducted with respondents from manufacturing and service organizations in Egypt. The data collected was analyzed using structural equation modelling. The results revealed that BCT adoption alone had a negative direct impact on ESCP. However, when this relationship was mediated by SCR and sequentially mediated by customer integration and green customer information sharing, the results were positively rehabilitated.
This research provides valuable insights into how organizations can adapt to dynamic business environments and extends the theories of KBV and ST. It offers an empirical contribution by filling the gap in a more comprehensive understanding of how ESCP can be enhanced by adopting BCT.

3. A novel off-chain channel model for blockchain-based solutions : doctoral dissertationBlaž Podgorelec, 2024, doctoral dissertation Abstract: This dissertation introduces a novel off-chain channel model aimed at enhancing existing solutions to address scalability challenges in blockchain technology. It begins with an overview of the problem statement, research objectives, methodology, and potential limitations before establishing a thesis and hypotheses. A comprehensive theoretical background on blockchain technology, scalability solutions, and the off-chain channel approach ensures a common understanding of the topic. To provide a thorough overview of existing off-chain channel solutions and identify and categorize their limitations, we conducted a systematic literature review, identifying 65 relevant studies. Through detailed analysis, six categories of solutions and six implemented off-chain channel solutions were identified. Five primary categories of limitations were also identified: routing, flexibility, privacy, network properties, and online assumptions, some with sub-limitations. To address these limitations, a new off-chain channel model, named ”Off-chain Channel as a Service,” is proposed, featuring four core design decisions: eliminating the need for an off-chain channel network, assuming blockchain properties by design, introducing a trustworthy service, and enabling flexibility by design. Validation and evaluation of the proposed model employ case-study and experiment research methods to confirm compliance with off-chain channel principles, validate it against identified limitations of existing solutions, analyze its impact on blockchain scalability, and assess its applicability across blockchain platforms. For this purpose, two off-chain payment channel prototype solutions have been implemented, each using a different underlying blockchain platform, namely Ethereum and Solana. Moreover, the proposed model’s security evaluation using risk-analysis methodology is also provided. Qualitative and quantitative analysis demonstrates that the proposed off-chain channel model adheres to off-chain channel principles, improves most identified limitations of existing solutions, positively impacts blockchain scalability, and can be applied to different blockchain platforms supported by smart contracts.

4. Blockchain technology adoption for improved environmental supply chain performance : the mediation effect of supply chain resilience, customer integration, and green customer information sharingSummer K. Mohamed, Sandra Haddad, Mahmoud Barakat, Bojan Rosi, 2023, original scientific article Abstract: Due to the complexity of building supply chain resilience (SCR) towards long-term environmental sustainability amendments, the use of emerging technologies such as Blockchain Technology (BCT) can be adopted as an innovative tool to enhance the sustainability and resilience of supply chains, especially in uncertain environments. Drawing on the Knowledge-Based View (KBV) and Dynamic Capability View (DCV), this research aims to demonstrate how the adoption of BCT can enhance the environmental supply chain performance (SCP). A total of 603 valid surveys were collected from respondents from manufacturing and service organizations in Egypt. The collected data were analyzed using structural equation modelling, and results revealed that BCT adoption alone had a negative direct impact on environmental SCP. However, when this relationship was mediated by SCR and sequentially mediated by customer integration and green customer information sharing, the results were positive. This research presents insights on how organizations can adapt to dynamic business environments, and, in addition, it extends the theories of KBV and DCV in an empirical contribution by filling the gap in understanding regarding how environmental SCP can be enhanced through the adoption of BCT.
