Today, globalized markets require more resilient and agile manufacturing systems, as well as customized and virtualized features. Classical self-standing manufacturing systems are evolving into collaborative networks such as Cloud Manufacturing (based on centralized knowledge and distributed resources) or Shared Manufacturing (based on fully decentralized knowledge and distributed resources) as a solution to ensure business continuity under normal as well as special circumstances. Additive Manufacturing (AM), one of the enablers of Industry 4.0 (I4.0), is a promising technology for innovative production models due to its inherent distributed capabilities, digital nature, and product customization ability. To increase the adaptivity of distributed resources using AM technology, this paper proposes a mechanism for sharing workload and resources under unexpected behaviours in the supply chain. Smart contracts and blockchain technology in this concept are used to provide decentralized, transparent, and trusted operation of such systems, which provide more resilience to disruptive factors. In this paper, the proposed Blockchain-based Shared Additive Manufacturing (BBSAM) protocol, ontology, and workflow for AM capacity pooling are discussed and analysed under special conditions such as anomalous demand. Discrete-time Python simulation on a real Italian AM market dataset, also provided, is available on GitHub.

The recent revolution in Industry 4.0 (IR 4.0) has characterized the integration of advance technologies to bring the fourth industrial revolution to scale the manufacturing landscape. There are different key drivers for this revolution, in this research we have explored the following among them such as, Industrial Internet of Things (IIoT), Deep Learning, Blockchain and Augmented Reality. The emerging concept from blockchain namely “Non-Fungible Token” (NFT) relating to the uniqueness of digital assets has vast potential to be considered for physical assets identification and authentication in the IR 4.0 scenario. Similarly, the data acquired through the deployment of IIoT devices and sensors into smart industry spectrum can be transformed to generated robust analytics for different industry use-cases. The predictive maintenance is a major scenario in which early equipment failure detection using deep learning model on acquired data from IIoT devices has major potential for it. Similarly, the augmented reality can be able to provide real-time visualization within the factory environment to gather real-time insight and analytics from the physical equipment for different purposes. This research initially conducted a survey to analyse the existing developments in these domains of technologies to further widen its horizon for this research. This research developed and deployed a smart contract into an ethereum blockchain environment to simulate the use-case for NFT for physical assets and processes synchronization. The next phase was deploying deep learning algorithms on a dataset having data generated from IIoT devices and sensors. The Feedforward and Convolutional Neural Network were used to classify the target variables in relation with predictive maintenance failure analysis. Lastly, the research also proposed an AR based framework for the visualization ecosystem within the industry environment to effectively visualize and monitory IIoT based equipment’s for different industrial use-cases i.e., monitoring, inspection, quality assurance.

Reversing the digital twin concept to control the physical entity with its virtual entity is an emerging field of research to ensure that the physical components of a production system mirror the simulation precisely. We present a novel concept for the integration of blockchain-based smart contracting into the reverse digital twin of a hybrid production. In this approach, a simulation model monitors and controls the physical system to increase transparency and to enable dynamic simulation of scenarios. To further increase transparency in the digital twin, the financial flow of the production processes is integrated by smart contracting. This ensures tamper-proof documentation of processes and can decrease information asymmetry between the multiple stakeholders interacting within a hybrid production. To validate the concept, we conduct a case study with the implemented digital twin to show its capabilities.
Blockchain 3.0, an advanced iteration of blockchain technology, has emerged with diverse applications encompassing various sectors such as identity authentication, logistics, medical care, and Industry 4.0/5.0. Notably, the integration of blockchain with industrial automation and control systems (IACS) holds immense potential in this evolving landscape. As industrial automation and control systems gain popularity alongside the widespread adoption of 5G networks, Internet of Things (IoT) devices are transforming into integral nodes within the blockchain network. This facilitates decentralized communication and verification, paving the way for a fully decentralized network. This paper focuses on showcasing the implementation and execution results of data preservation from industrial automation and control systems to IOTA, a prominent distributed ledger technology. The findings demonstrate the practical application of IOTA in securely preserving data within the context of industrial automation and control systems. The presented numerical results validate the effectiveness and feasibility of leveraging IOTA for seamless data preservation, ensuring data integrity, confidentiality, and transparency. By adopting IOTA’s innovative approach based on Directed Acyclic Graph (DAG), the paper contributes to the advancement of blockchain technology in the domain of Industry 4.0/5.0.
The emergence of Industry 5.0 has highlighted the significance of information usage, processing, and data analysis when maintaining physical assets. This has enabled the creation of the Digital Twin (DT). Information about an asset is generated and consumed during its entire life cycle. The main goal of DT is to connect and represent physical assets as close to reality as possible virtually. Unfortunately, the lack of security and trust among DT participants remains a problem as a result of data sharing. This issue cannot be resolved with a central authority when dealing with large organisations. Blockchain technology has been proposed as a solution for DT information sharing and security challenges. This paper proposes a Blockchain-based solution for digital twin using Ethereum blockchain with performance and cost analysis. This solution employs a smart contract for information management and access control for stakeholders of the digital twin, which is secure and tamper-proof. This implementation is based on Ethereum and IPFS. We use IPFS storage servers to store stakeholders' details and manage information. A real-world use-case of a production line of a smartphone, where a conveyor belt is used to carry different parts, is presented to demonstrate the proposed system. The performance evaluation of our proposed system shows that it is secure and achieves performance improvement when compared with other methods. The comparison of results with state-of-the-art methods showed that the proposed system consumed fewer resources in a transaction cost, with an 8% decrease. The execution cost increased by 10%, but the cost of ether was 93% less than the existing methods.
Kwaku Adu-Amankwa is a PhD candidate at the University of Strathclyde, Glasgow, United Kingdom, based within the department of Design, Manufacturing and Engineering Management, and affiliated with the Centre for Internet Law & Policy. He researches complex security relationships associated with IP of additive manufacturing (3D printing) applications within digitally enabled/transformed supply chains. Angela Daly is a Professor of Law at the University of Dundee, Dundee, United Kingdom, jointly appointed by the Leverhulme Research Centre for Forensic Science and Dundee Law School. She conducts research across IP, data protection, competition and sector-specific regulation and human rights law. Digital supply chains (DSCs) provide several advantages over traditional physical supply chains, yet they also pose new risks, including for IP, especially when associated with three-dimensional ‘3D’ printing (3DP), also known as additive manufacturing (AM). Technological protection measure (TPM) usage in DSCs may help address the IP security issues of 3DP or AM but may result in overprotection and disregard for IP exceptions, which may also have a negative impact on innovation and other goals such as sustainability. This article considers how the IP security of 3DP/AM is addressed in DSCs, including by applying TPMs. We discuss whether the current approaches strike the right balance between the competing interests of different DSC actors. We also present some novel findings from a survey conducted with expert stakeholders to better understand IP security issues in practice. Our findings show that most respondents see IP and IP security efforts as both barriers and enablers to using 3DP/AM within DSCs. Also, the strategy chosen by most respondents for securing IP focuses on a technical approach, using inter alia TPMs. We infer that this dual perspective on IP and IP security may reflect the respondents’ differing relationship with IP in DSCs, where one may wish to create, use and secure their own IP but also encounter barriers through the inaccessibility of the IP of third parties. In the Internet age, the relationship between IP and digital technologies has become the subject of intense debate, giving rise to legislative reforms, a vast body of case law and commercial and technical adaptations extensively documented in academic literature.1 While most of the attention has focused on copyright, the interaction of digital technologies with other IP rights, such as trade marks and patents (eg for keyword advertising and software and hardware patents), has also attracted scrutiny.2 Furthermore, questions over the ownership of data and trade secrets, data and algorithms also have IP-relevant aspects.3 As digital technologies, usually Internet enabled, have evolved, the debate has moved to new areas, including Internet-of-Things (IoT), artificial intelligence (AI) and smart manufacturing, especially three-dimensional ‘3D’ printing (3DP) or additive manufacturing (AM). In many cases, these technologies give rise to interconnected issues, as they are deployed simultaneously, so that, eg a 3DP machine is part of the IoT.4 These new technologies are also vehicles for IP creation and dissemination and, in some cases, IP overreach and present issues for securing and utilizing IP, increasing the complexity of the debate. Digitalization facilitates decentralized manufacturing through a variety of technologies including 3DP, which relies on digital design files provided through digital communications means, such as the public Internet (especially for hobbyists using sites such as Thingiverse).5 Larger industrial production using digital manufacturing may mobilize securer, private networks to send and receive files and other necessary information or data to produce objects.6 In these ways, traditional supply chains, which previously typically involved centralized production in a large factory (often in China) and the distribution of products by sea, air and train, are transitioning to a different model, involving more decentralized and diffuse production, geographically closer to the end user.7 The more traditional supply chain model experienced various IP security issues, such as copycat production, including in factories that may have produced legitimate versions of products by day and counterfeit versions by night.8 However, digital supply chains (DSCs) may present more opportunities for IP infringement and, thus, reduce security for IP owners. DSCs integrating 3DP offer advantages over conventional supply chains and centralized manufacturing in terms of increased sustainability, convenience and less wastage.9 We have seen the tangible value of decentralized smart production and DSCs during the early part of the coronavirus disease 2019 (COVID-19) pandemic, which significantly disrupted traditional supply chains, especially for high-demand medical and health products, including personal protective equipment such as facemasks and testing kits.10 However, DSCs and smart manufacturing raise new concerns about IP security, as IP travelling along DSCs may be vulnerable to being hacked or misappropriated through the supply chain.11 Also, digital files in the supply chain may also contain material that would infringe the IP of others. Commentators have been raising concerns about IP security in digital manufacturing, especially 3DP, as part of broader concerns about new manufacturing technologies, such as 3DP’s disruptive effect on the theoretical underpinnings and effective enforcement of IP.12 Again, the issue of IP security and countervailing interests, including access to knowledge and medical treatment, emerged during the COVID-19 pandemic, where a particularly prominent case involved two engineers in Italy making replacement parts for a patented ventilator machine used to treat COVID patients threatened with litigation for allegedly infringing the patent.13 While in the end the case never reached a court, and the engineers may have been able to avail themselves of an exception to infringement, such threats may have a chilling effect on the use of distributed smart manufacturing.14 In this article, we focus on the issue of IP security in DSCs for smart manufacturing using 3DP or AM to consider (i) the extent to which IP is disrupted or weakened in DSCs and (ii) how IP is secured in these chains to mitigate such concerns. We summarize the relationship between 3DP and the law, focusing on IP, before considering how technical IP security measures have been mobilized in predecessor digital technologies. Here, we will focus on the debate around technological protection measures (TPMs) and digital rights management (DRM) as technical means of enforcing IP security. We consider how TPMs have been deployed in Internet-enabled content supply chains during the 1990s and 2000s, as well as the controversial legislative updates that accommodated DRM in that era, including the extent to which the right balance was struck between competing rights and We more in IP security in DSCs before research on this we offer AM as The of to parts from three-dimensional model usually as to manufacturing and manufacturing As by 3DP or AM physical and digital or products used to produce a from a digital model the industrial in the manufacturing has the manufacturing approaches distributed or different supply chain are involved in making a In digital manufacturing, supply chain are to and digital data may contain or as well as physical both These from more traditional manufacturing the industrial as the 3DP a three-dimensional from a digital design and which are in a to the using a large of material from which the is AM various advantages over traditional including and the to produce or that would be to traditional AM is known as 3DP as including in the body of on the so we this to the and manufacturing 3DP in various and at different with the printing in for that other such as and or of However, hardware and design such as along with 3DP the of 3DP to manufacturing In with a access to and an to produce that previously be on a usually This a of and However, as may be by the of 3DP has been as as may be other barriers to including the that some technical knowledge would the or of and for the and the of 3DP to and in many of law with 3DP and or and IP are these of law.

As agile manufacturing expands and workforce mobility increases, the importance of efficient knowledge transfer among factory workers grows. Cognitive Assistants (CAs) with Large Language Models (LLMs), like GPT-3.5, can bridge knowledge gaps and improve worker performance in manufacturing settings. This study investigates the opportunities, risks, and user acceptance of LLM-powered CAs in two factory contexts: textile and detergent production. Several opportunities and risks are identified through a literature review, proof-of-concept implementation, and focus group sessions. Factory representatives raise concerns regarding data security, privacy, and the reliability of LLMs in high-stake environments. By following design guidelines regarding persistent memory, real-time data integration, security, privacy, and ethical concerns, LLM-powered CAs can become valuable assets in manufacturing settings and other industries.
Živimo u globalnom, kulturološki različitom i tehnološki naprednom svijetu gdje se ‹high-tech› implementirao u gotovo svaku poru ljudskog djelovanja, a što je potencirala i dvogodišnja pandemija Covid-19 koja je „fizičke“ međuljudske odnose svela na minimum. U isto pak vrijeme, kao posljedica velikih socioloških, političkih i ekonomskih promjena vezanih uz postojeće i novonastale centre moći, nastaje jedna nova podvrsta, odnosno manifestacija digitalne umjetnosti nazvana kriptoumjetnost. U navedenom radu će se istražiti i pokazati kontekstualne veze između kriptoumjetnosti i kriptotržišta, glavnih pokretača i nositelja tih novih brzorastućih pojava mlađe generacije poduzetnika većinom IT industrije. Oni, ne prihvaćajući sustav vrijednosti „starih“ interesnih skupina čije se bogatstvo odnosno moć temelji na „starim“ prirodnim resursima (uglavnom naftnim), stvaraju svoj novi sustav vrijednosti baziran na manipulacijama vlastito stvorenih kriptovaluta stvarajući kriptotržište koje onda postaje njihov vlastiti centar moći baziran na subjektivnim manipulacijama, a unutar čega će se na raznim virtualnim platformama, odnosno Web 3.0 granama, istim tehnologijama kao i kod kriptovaluta (‹blockchain›) trgovati, odnosno posjedovati kriptoumjetnička djela, tj. NFT-jevi (‹Non-Fungible-Token›). S tim u vezi posebno će se istaknuti jedinstvenost vlasništva nad radovima kriptoumjetnosti, odnosno tehnologiji koja pojedino umjetničko djelo čini unikatom te pridati pozornost ‘otvorenom’ virtualnom tržištu, relativno jednostavno dostupnom svim zainteresiranim konzumentima, autorima ili kupcima. Cilj rada je identificirati pojam kriptoumjetnost, definirati njezine dijelove, odnosno analizirati pojedine segmente vizualnog NFT projekta, metodom komparacije naznačiti sličnosti i razlike unutar šire grupe digitalne umjetnosti kojoj pripada, dati uvid odnosno znanstveni prikaz raznovrsnih vizualnih NFT projekata i njihovih najznačajnijih autora NFT scene te, na kraju, hipotetski zaključiti postoji li, u sada već, mogli bismo reći, hiperprodukciji umjetničkih NFT radova međusobnih (estetskih) poveznica. Odnosno, možemo li govoriti o kolektivnoj estetici NFT radova unutar područja kriptoumjetnosti, odnosno uopće o (kripto)umjetnosti. U radu će se također istaknuti načini izlaganja te prihvaćanja NFT umjetničkih djela od strane institucija koje su tradicionalno mjerodavne u potvrđivanju valjanosti, odnosno vrijednosti umjetničkog djela kao što su muzeji, galerije, aukcijske kuće, kolekcionari, teoretičari i kritičari i sl.
Security and privacy are primary concerns in IoT management. Security breaches in IoT resources, such as smart sensors, can leak sensitive data and compromise the privacy of individuals. Effective IoT management requires a comprehensive approach to prioritize access security and data privacy protection. Digital twins create virtual representations of IoT resources. Blockchain adds decentralization, transparency, and reliability to IoT systems. This research integrates digital twins and blockchain to manage access to IoT data streaming. Digital twins are used to encapsulate data access and view configurations. Access is enabled on digital twins, not on IoT resources directly. Trust structures programmed as smart contracts are the ones that manage access to digital twins. Consequently, IoT resources are not exposed to third parties, and access security breaches can be prevented. Blockchain has been used to validate digital twins and store their configuration. The research presented in this paper enables multitenant access and customization of data streaming views and abstracts the complexity of data access management. This approach provides access and configuration security and data privacy protection.

This study aims to portray a conceptual framework of Blockchain and AI-based DTs and outline its key characteristics, requirements, and system architecture by composing a functional model using IDEF0. Such an approach is expected to enhance predictive maintenance in building facilities, simplify the management and operation of smart built environments, and ultimately deliver valuable outcomes for facility operators, real estate practitioners, and end-users.
As part of TIV's DHW on Vehicle 5.0, this letter introduces a novel concept, Logistics 5.0, to address high complexities in logistics Cyber-Physical-Social Systems (CPSS). Building upon the theory of parallel intelligence and leveraging advanced technologies and methods such as blockchain, scenarios engineering, Decentralized Autonomous Organizations and Operations (DAOs), Logistics 5.0 promises to accelerate the paradigm shift towards intelligent and sustainable logistics. First, the parallel logistics framework is proposed, and the logistics ecosystem is discussed. Then, the human-oriented operating systems (HOOS) are suggested to providing intelligent Logistics 5.0 solutions.

Information technologies are transforming conventional supply chain management (SCM) business practices and positively influencing sustainability. In particular, blockchain technology and the internet of things (IoT) are two important examples that play a significant role in sustainable supply chain management (SSCM). This chapter reviewed the impact of these technologies on SSCM separately and with their combination of forward and reversed supply chains. Academics and practitioners have studied the effects of these technologies on sustainability separately earlier, but integrating these technologies can lead to different insights and disclose several opportunities. Besides, the chapter highlights essential factors in developing blockchain and IoT to know the modern trends for industry automation, challenges, and future research opportunities on supply chain sustainability. Finally, the chapter presents an IoT-based service-oriented blockchain architecture for supply chain information systems that manifest the information-driven sustainability of the supply chain operation.
Blockchain technology, as a well-known technology in financial spaces, has many advantages in non-financial industries and supply chains. Two of the main benefits of blockchain technology are smart contracts and distributed decision-making processes. These features can be especially useful in implementing Industry 4.0. Moreover, this technology can increase productivity in supply chains by enhancing transparency, reducing operational costs, and improving monitoring and supervision throughout the lifecycle of products. In this paper, we introduce a blockchain-based architecture for a supply chain in cloud architecture. This approach leads to the more efficient implementation of Industry 4.0 and increases sustainability in the supply chain. In this study, we aim to investigate whether the proposed blockchain-based platform affects sustainability in the supply chain. From a sustainability perspective, we solve the large-scale problem of a cloud-based production–distribution system in centralized and distributed states. The results of the solution indicate a significant improvement in the decentralized state compared to the centralized state and this improvement enhances sustainability in the supply chain. We verify the proposed model by considering an axiomatic design algorithm. In the distributed model, the system cost is reduced by up to 45%, and the solving time is decreased by approximately 51% in pessimistic conditions and by about 87% in optimistic conditions. These improvements directly enhance economic and environmental sustainability, resulting in reduced energy consumption.

The Metaverse has been recently envisioned as the next technological revolution with the idea of building fully immersive virtual worlds where users can interact with each other and with mixed-reality environments and objects. The relationship between the digital and the physical worlds represents a challenging opportunity to foster the idea that virtual experiences and interactions can complement and enhance reality enabling the definition of new use cases and services. In this context, Metaverse’s technologies need to rely on a connected, trustworthy, and highly detailed digital representation of users and objects to build an effective virtual world based on trusted and fresh information from the physical world. The need to decouple responsibilities through a multi-layered vision allows Metaverse’s applications to focus only on their business goal by relying on a cyber-physical layer enabling bi-directional communication with users and devices, accessing trusted information, invoking available actions, and retrieving immutable historical data. In this paper, we analyze and propose the combination of Digital Twins and Blockchain technologies as strategic pillars for bridging the gap between the virtual and the physical worlds and supporting the creation of the Metaverse.

Core enterprises are entering into close collaborations with multi-level manufacturing service providers to create and share value. However, credible data sharing in collaborative manufacturing supply chains is rare, which can lead to uncontrollable production distortions and delayed operational adjustments. Driven by blockchain technology, this study proposes a systematic framework for credible manufacturing data sharing for a cross-enterprise collaborative manufacturing supply chain (CMSC). To develop the needed method, a blockchain network system with blockchain nodes, distributed ledger, and Raft-based distributed node ordering service system was first modelled. Then, two automatic data upload algorithms were studied to ensure the reliability of off-chain manufacturing data sources from core enterprises, suppliers, and customers. Then, two types of smart contracts were designed to ensure the standardisation and co-validation of manufacturing data storage and query processes in the blockchain network. A demonstrative case was studied to validate the proposed blockchain-based credible manufacturing data sharing method. The results show that our work is effective for credible data sharing in CMSC, which makes it easier for core enterprises to better operate the CMSC and further stimulate enterprises to create a credible social community.
The traditional mode of cooperation between enterprises still suffers from major problems, including data privacy leakage, data falsification, and inefficient collaboration in data sharing. These challenges make it difficult for enterprises to ensure that their cooperative suppliers adopt sustainable practices in standards identification and operation processes. This paper proposes a “Value–Standard–Process” collaborative framework for blockchain-based enterprise data governance that helps ensure a high degree of data security, a high reliability of collaborative tasks, and a high transparency of value transformation. First, this paper proposes a new collaborative mode for blockchain-based manufacturing in the sharing economy, including the non-linear dynamic evaluation and value balancing mechanism of data with multiple attributes, a trusted data governance mechanism for blockchain-based manufacturing, and a smart contract generation mechanism for value-driven collaboration. Second, this paper explains these three components and the implementation of the overall framework. Third, this paper verifies the applicability and achievability of the proposed framework through experiments. Establishing the value-driven multi-level blockchain-based collaboration mode facilitates the effective flow of production factors and promotes trust in the digital economy of sustainability.

Supply chain networks are complex structures which introduce significant challenges regarding transparency in production and traceability of components, making product certification non-trivial. Visibility within quality assurance processes is critical to this and is particularly important for autonomous & driver-less vehicles which rely on correct operation of individual parts (in the absence of human intervention) to achieve safety of such vehicles. Failure to ascertain quality assurance of parts can result in rogue behaviour among driver-less vehicles which can result in a risk to human lives. In this paper, a blockchain-based approach - TruCert, is proposed which achieves trustworthy product certification through enhanced visibility within tier 1 and beyond for complex automotive supply chains. Leveraging blockchain technology, TruCert’s potential to improve product quality assurance is demonstrated whilst also strengthening supply chain resilience to combat risks and uncertainties. Utilising the use-case of autonomous connected vehicles manufacturing, design and development of TruCert solution is presented including detailed system design, data model, and smart contracts & oracle implementations. TruCert enables trustworthy part certification across supply chain beyond tier 1 whilst achieving interoperability with heterogeneous systems across suppliers and other stakeholders. Outcomes of evaluation with respect to cost, performance, and security are also presented which highlight the effectiveness of the approach whilst identifying directions for future work.

Occupational stress among health workers is a pervasive issue that affects individual well-being, patient care quality, and healthcare systems' sustainability. Current time-tracking solutions are mostly employer-driven, neglecting the unique requirements of health workers. In turn, we propose an open and decentralized worker-centered solution that leverages machine intelligence for occupational health and safety monitoring. Its robust technological stack, including blockchain technology and machine learning, ensures compliance with legal frameworks for data protection and working time regulations, while a decentralized autonomous organization bolsters distributed governance. To tackle implementation challenges, we employ a scalable, interoperable, and modular architecture while engaging diverse stakeholders through open beta testing and pilot programs. By bridging an unaddressed technological gap in healthcare, this approach offers a unique opportunity to incentivize user adoption and align stakeholders' interests. We aim to empower health workers to take control of their time, valorize their work, and safeguard their health while enhancing the care of their patients.
Intelligent manufacturing under Industry 4.0 assimilates sophisticated technologies and artificial intelligence for sustainable production and outcomes. Blockchain paradigms are coined with Industry 4.0 for concurrent and well-monitored flawless production. This article introduces Sustainable Production concerned with External Demands (SP-ED). This method is more specific about energy production and the distribution for flawless and outage-less supply. First, the energy demand is identified for internal and external users based on which sustainability is planned. Secondly, Ethereum blockchain monitoring for a similar production and demand satisfaction is coupled with the production system. From two perspectives, the monitoring and condition satisfaction processes are validated using federated learning (FL). The perspectives include demand distribution and production sustainability. In the demand distribution, the condition of meeting the actual requirement is validated. Contrarily, the flaws in internal and external supply due to production are identified in sustainability. The failing conditions in both perspectives are handled using blockchain records. The blockchain records reduce flaws in the new production by modifying the production plan according to the federated learning verifications. Therefore, the sustainability for internal and external demands is met through FL and blockchain integration.
A digital twin (DT) is a virtual replica of a physical system that allows simulation, optimization, and predictive maintenance. Its challenges include the need for accurate and up-to-date data as well as the complexity of integrating different systems and technologies. This paper explores the potential of combining digital twin and blockchain technologies to create next-generation transportation systems that are more efficient, secure, and sustainable. DTs can be used to simulate and optimize transportation operations and maintenance, while blockchain can enhance security and transparency in data exchange and transaction verification. By integrating these technologies, transportation systems can become more resilient, adaptable, and responsive to changing demands and challenges. This paper provides an overview of the key concepts and applications of DTs and blockchain in transportation, including use cases such as autonomous vehicles, smart logistics, and mobility as a service. It also discusses the technical and organizational challenges of implementing these technologies and suggests potential solutions and research directions. Specifically, this paper argues that DT and blockchain technologies have the potential to transform transportation systems into more efficient, sustainable, and equitable systems that can meet the needs of present and future generations.
