“…For that purpose, the city digital twin is perceived as enabling technology to promote situational awareness for city management and to provide a city information model; that is, the city digital twin can collect, monitor, and manage city data [34]. For instance, it can reflect citizens' health condition [58]; represent, reason, and analyze energy consumption data [33,55,65]; detect motion for public security activities [42]; monitor noise pollution in the city using dynamics modeling [61]; provide real-time tracking of information during disasters and localize vulnerable objects [50,56]; and track and monitor individuals' behavior and localize disruptions and potential risks for emergency and disaster management [57,64,68]. It is also anticipated to enhance risk analysis and prevention and identify information flows for disaster management [60,69].…”

The city digital twin is anticipated to accurately reflect and affect the city’s functions and processes to enhance its realization, operability, and management. Although research on the city digital twin is still in its infancy, the advancement of the digital twin technology is growing fast and providing viable contributions to augmenting smart city developments. This study reviews the literature to identify the current and prospective potentials and challenges of digital twin cities. A research agenda is also proposed to guide future research on the city digital twincity digital twin to reach the utmost level of a comprehensive and complete city digital twin. Enhancing the efficiency of data processing, promoting the inclusion of socio-economic components of the city, and developing mutual integration between the two counterparts of the digital twin are proposed to be the future research directions to achieve and utilize a completely mirrored city digital twin.

“…Castelli et al suggested organizing the city digital twin into layers to integrate the city's various domains and dimensions [34]. In addition, Radenkovic et al pointed out the availability of using "loosely coupled" models to overcome the complexity of the physical counterpart and its multiple domains [61].…”

“…In prospect, this might lead to the development of several CDTs for the same city as a more easy-to-handle modular approach to the digitalization of the city (Wan et al, 2019). And yet, there remains the issue of integrating or at least loosely coupling together (Radenkovic et al, 2020) differently designed DTs. It does not surprise that the interviewed leading engineer part of the smart city unit of Dublin city council claimed that "one of their biggest challenges is currently the interoperability across the projects developed by different stakeholders.…”

No longer hype, not yet mainstream? Recalibrating city digital twins' expectations and reality: a case study perspective

While the concept of digital twin has already consolidated in industry, its spinoff in the urban environment—in the form of a City Digital Twin (CDT)—is more recent. A CDT is a dynamic digital model of the physical city whereby the physical and the digital are integrated in both directions, thus mutually affecting each other in real time. Replicating the path of smart cities, literature remarks that agendas and discourses around CDTs remain (1) tech-centered, that is, focused on overcoming technical limitations and lacking a proper sociotechnical contextualization of digital twin technologies; (2) practice-first, entailing hands-on applications without a long-term strategic governance for the management of these same technologies. Building on that, the goal of this article is to move beyond high-level conceptualizations of CDT to (a) get a cognizant understanding of what a CDT can do, how, and for whom; (b) map the current state of development and implementation of CDTs in Europe. This will be done by looking at three case studies—Dublin, Helsinki, and Rotterdam—often considered as successful examples of CDTs in Europe. Through exiting literature and official documents, as well as by relying on primary interviews with tech experts and local officials, the article explores the maturity of these CDTs, along the Gartner's hype-mainstream curve of technological innovations. Findings show that, while all three municipalities have long-term plans to deliver an integrated, cyber-physical real-time modeling of the city, currently their CDTs are still at an early stage of development. The focus remains on technical barriers—e.g., integration of different data sources—overlooking the societal dimension, such as the systematic involvement of citizens. As for the governance, all cases embrace a multistakeholder approach; yet CDTs are still not used for policymaking and it remains to see how the power across stakeholders will be distributed in terms of access to, control of, and decisions about CDTs.

“…Blockchain technology prevents abuses in the sense of forging and denying content since it saves complete records in data blocks in sequences with timestamps, where old and new data blocks cannot be deleted, whereas a cryptographic algorithm prevents the unauthorized imputation of data and reduces the possibility of fraud [24]. Due to these characteristics, blockchain technology is used in different sectors, such as finance [48], business operations [38], the health system [49], tourism [50], the energy sector [51], the public sector [52] and education [31,53].…”

Following COVID-19, new accreditation standards include digitization, entrepreneurship, social inclusion and the circular economy. Blockchain can help to simplify difficult accreditation processes that ensure worldwide teaching, learning, practice and business communication excellence. The paper proposes a Collaborative Learning and Student Work Evaluation (CLSWE) model based on blockchain technologies (BCTs) encompassing selected concepts from the scientific research peer-review process. BCTs are used to develop a safe platform for storing and exchanging data about students’ projects and evaluations. The CLSWE model offers the possibility of improving cooperation between higher-education institutions and companies that seek the “employable skills” of proactive students. Before implementing the CLSWE model, a questionnaire was conducted to survey lecturers about their attitudes related to the potential application of BCTs. The results of the surveys are encouraging and reveal a desire and willingness to introduce BCTs in education. A project scheme with the main functionalities of the model and a description of the roles of the prominent participants was designed. A platform with a database created in the MySQL language for the testing model was built. This research also contributes to higher education literature in terms of the sustainability of the education process and collaborative learning with BCTs.
