Methodology
Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were employed (Andronie et al. 2021).Throughout January and May 2022, a quantitative literature review of ProQuest, Scopus, and the Web of Science databases was carried out, with search terms including "city" + "blockchain technology", "smart contracts", and "decentralized governance systems".As the analyzed research was published between 2016 and 2022, only 371 sources satisfied the eligibility criteria.Excluded, out of scope, and insufficiently detailed records, together with limited rigor, have resulted in a selection of 39 predominantly empirical sources (Tables 1 and 2).A Shiny app was harnessed for the PRISMA flow diagram to include evidence-based acquired and handled data.Analyzing the most recent and relevant sources and leveraging screening and quality assessment tools such as AMSTAR (Assessing the Methodological Quality of Systematic Reviews), Dedoose (investigating qualitative and mixed methods research), Distiller SR (that harnesses artificial intelligence and data-driven workflows, automating reference gathering, screening, and assessment), ROBIS (bias risk assessment tool in systematic reviews), and SRDR (Systematic Review Data Repository), we integrated the core outcomes and robust correlations related to smart urban governance.As data visualization tools, for initial bibliometric mapping dimensions was harnessed, together with layout algorithms provided by VOSviewer with respect to co-authorship (Figure 1), citation (Figure 2), bibliographic coupling (Figure 3), co-citation (Figure 4), and PRISMA flow diagram indicating the search outcomes and screening (Figure 5).Blockchain technologies can be harnessed in the smart governance of data-driven cities. Blockchain-based smart governance systems entail public engagement for scalable and efficient data sharing through infrastructure maintenance.(Bai et al. 2022;Khan et al. 2020;Kundu 2019;Sifah et al. 2020;Sun et al. 2016) Seamless data sharing reliability, scalability, and interoperability are enabled by the decentralized system of blockchain technology and integrated in smart city planning, leading to informed decisions and actions.Smart contracts are pivotal in transactions on blockchain platforms, configuring cutting-edge governance arrangements.(Beck et al. 2018;Howell and Potgieter 2021;Lin et al. 2022;Marsal-Llacuna 2020;Rikken et al. 2019;Wong et al. 2020) Internet of Things-driven smart city applications assimilate scalable networked interoperability across urban environments and data resource management through self-governing and immutable transactions.Blockchain-enabled software tools are pivotal in decentralized algorithmic governance infrastructures.(Alasbali et al. 2022;Hooper and Holtbrügge 2020;Lăzăroiu and Harrison 2021;Mora et al. 2021;Reinsberg 2021;Rozas et al. 2021) Smart city governance enables collaborative participation through decision-making tools and spatial cognition algorithms.Blockchain technology can enable smart governance using data-driven technologies and value-making processes.(Bai et al. 2022;Khan et al. 2020;Nica 2021;Sifah et al. 2020;Sotoudehnia 2021;Sun et al. 2016) The distributed structure of blockchain technology enables smart contracts.The blockchain technology can shape public management structures across the smart governance system through automated collaborative processes and behaviours.(Beck et al. 2018;Blakemore and Kral 2021;Hassija et al. 2021;Murray et al. 2021;Shan et al. 2021;Viano et al. 2022;Wong et al. 2020)          Citation correlations have covered how blockchain technology and applications, by leveraging digital twinning, analytic decision models, and visual recognition tools, can reconfigure organizational governance mechanisms.Using blockchain technology and edge computing, citizen participation in smart urban planning requires data management capabilities.Blockchain technology, by the use of spatial computing technology, interconnected virtual simulations, and geolocation data, leverages decentralized applications in smart contracts, reconfiguring organizational structures and business models.Blockchain technology, by deploying spatial data mining, cognitive technologies, and virtual reality tools, assists networked cyber-physical systems and smart contracts in seamless data sharing and infrastructure mapping.
