Logistics is defined as the process of transporting, storing, and delivering goods from the producer to the final user. In today’s globalized world, logistics have become increasingly complex, making it imperative to address challenges related to data integrity, transparency, and secure storage. The incorporation of IoT devices in logistics allows for real-time monitoring of goods, vehicles, and environmental conditions. However, this generates vast amounts of data, which necessitates a reliable and secure data storage and management system. These aforementioned issues can be addressed by deploying a blockchain-based solution. Blockchain is an innovative technology that operates on a decentralized database system and it has different applications which include finance, healthcare, and so on. This research proposed a blockchain-IoT-based model for enhancing the logistics process. The proposed model utilized the Interplanetary file system for the secured and efficient storage of logistics data on a distributed and decentralized network and the SHA-256 hashing algorithm to ensure the anonymity of users’ private information. The model also establishes rules by using smart contracts, which increases efficiency. The performance evaluation of the proposed model was done based on the security, latency, cost, and throughput of the transaction. The experimental results and performance evaluation show that the proposed model is more efficient and secure than the existing blockchain-based systems. Additionally, the proposed model offers the real-time monitoring of goods while in transit. The proposed model offers the solution to the security, storage, and interoperability challenges in the IoT logistics system. It also provides recommendations to logistics stakeholders to adopt blockchain technology. Despite the implications, the limitation of this study is that it was tested in a controlled environment.
Purpose Blockchain is a developing technology that affects numerous industries, including facility management (FM). Many barriers are associated with adopting blockchain-enabled building information modeling (BEBIM) in FM. This research aims to identify and prioritize the barriers to adopting BEBIM in FM. Design/methodology/approach To address the knowledge gap, this study employs a two-phase methodology for evaluating the barriers to adopting BEBIM in FM. The first phase involves a comprehensive literature review identifying 14 barriers to BEBIM adoption. Using a Delphi approach, the identified barriers were categorized into 6 groups and finalized by 11 experts, adding 3 more barriers to the list.

Worldwide, shipping documents are still primarily created and handled in the traditional paper manner. Processes taking place in shipping ports as a result are time-consuming and heavily dependent on paper. Shipping documents are particularly susceptible to paperwork fraud because they involve numerous parties with competing interests. With the aid of smart contracts, a distributed, shared, and append-only ledger provided by blockchain technology allows for the addition of new records. In order to increase maritime transport and port efficiency and promote economic development, this paper examines current maritime sector developments in Iraq and offers a paradigm to secure the management system based on a hyper-ledger fabric blockchain platform. The performance evaluation of the proposed system implies two scenarios: one organization and two organizations by examining throughput and latency. High transaction transmission rates on large block sizes produced positive results. Similarly, employing a small block size and higher send rates results in poor performance. Additionally, it was noted that throughput will decrease and latency will rise as the number of organizations increases. Block size and block timeouts should be high in applications with many concurrent transactions in order to maintain good throughput.

Digital transformation plays a key role in improving information sharing and information processing in supply chains. Specifically, maritime supply chains require numerous data and document exchanges and can significantly benefit from digital information sharing (DIS). This notable potential has attracted attention and has resulted in a growing number of studies on blockchain platforms, cloud-based platforms, and other digital technology platforms. However, DIS adoption and execution is a complex process as it depends on various success factors and barriers and affects numerous capabilities and performance outcomes. Moreover, various information systems and management theories can be utilised to underpin these relationships. Our study aims to conduct a systematic literature review that uncovers dynamic capabilities, barriers, enablers and outcomes of DIS with blockchain and cloud-based platforms, illustrates the relationship between them, and discloses methods and theories applied in supply chains. We discuss different use cases of blockchain and cloud-based platforms for DIS in various business functions in supply chains. Particularly, we reveal six DIS-powered capabilities, five performance outcomes improved by the DIS, eight main barriers, and nine enablers of DIS implementation. The lack of theoretical underpinning and causal empirical studies is identified as an important gap in the literature. This study also presents precise future research directions that can help address these gaps.
Blockchain technology has experienced a tremendous increase in popularity in recent years due to its potential to change a number of industries, including finance, healthcare, and logistics. One of the key features of blockchain technology is its capacity to provide safe authentication and permission. In order to maintain and verify identities and rights, traditional authentication and authorization techniques rely on a centralised authority. However, this strategy has a number of shortcomings, including single points of failure, security flaws, and constrained scalability. A decentralised, secure method of maintaining identities and permissions is provided by blockchain technology. The development of a transparent, impenetrable record of all transactions and data is made possible by blockchain technology. The positives of adopting blockchain technology for authentication and authorisation over more traditional methods are examined in this article, along with its cons and potential applications. This study contributes to the evolving discourse on blockchain technology by specifically examining its applications in authentication and authorization systems. By investigating the strengths and weaknesses of this decentralized approach, we aim to provide valuable insights for researchers, practitioners, and decision-makers seeking to harness the full potential of blockchain in enhancing security and transparency in identity management.

Blockchain technology will soon change the way reliable transactions work. By combining distributed cryptographic methods, immutable ledgers, Transactions, and financial audit trails that will be recorded in consensus validation, communication can now use blockchain technology for business advantage. A blockchain-based business version is currently under consideration because they promise to guarantee trust, identity management, reputation management, processing time, reduced fees, and fraud in commercial transactions. However, the current problem is that there needs to be more research into how ready businesses are to use blockchain and at what cost. This study examines the mediating and moderating effects of perceived costs on the relationship between an organization’s readiness to adopt blockchain and its intention to accept it as something new. This study uses empirical and quantitative analysis methods in reviewing the document-based multiscale questionnaire that has been developed. In this study, we collected data from blockchain experts and used the Partial Least Square Structural Equation Model (PLS-SEM) analysis tool to test the assumptions of our framework. This study also uses Key Performance Map Analysis (IPMA) to explore the potential management impact of this issue, which is a novelty in previous studies. The results show that rather than mediating the relationship between Acceptance of Technology Readiness (TeRa) and intention to adopt blockchain, the perceived costs change. According to IPMA’s analysis, the most critical factor behind the desire to adopt blockchain is the perceived cost, with the highest support structure rating. This research is expected to assist decision-makers and stakeholders in developing and improving the latest performance and features needed for the successful implementation of this blockchain technology.
Financial technology and green finance have an irreplaceable position in today's society. The relationship between the two is becoming increasingly close due to the diversification of economic development.
