The aim of our systematic review was to inspect the recently published literature on decentralized governance systems and integrate the insights it articulates on blockchain technology and smart contracts by employing Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. 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 studies were published between 2016 and 2022, only 371 sources satisfied the eligibility criteria. 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, Dedoose, Distiller SR, ROBIS, and SRDR, we integrated the core outcomes and robust correlations related to smart urban governance. As data visualization tools, for initial bibliometric mapping dimensions were harnessed, together with layout algorithms provided by VOSviewer. Future research should investigate smart contract governance of blockchain applications and infrastructure using decision-making tools and spatial cognition algorithms.

AbstractCompanies and industries face various challenges when it comes to embracing the circular economy (CE). These challenges not only deter companies from adopting effective strategies that promote it but also hinder industries from effectively establishing a circular system that ensures the addition of economic value to the supply chain. To address these challenges, blockchain technology has emerged as a new and revolutionary protocol for sharing and updating information. It does so by linking databases within a decentralized, peer‐to‐peer, open‐access network, guaranteeing secure, immutable, and irreversible operations. Within this context, the primary objective of this article is to investigate how blockchain technology supports the transition to the CE. Additionally, the paper aims to identify the barriers that hinder the process of transitioning to the CE. To achieve this, a systematic literature review (SLR) was conducted, considering 22 articles published in recent years across Scopus, Web of Science, and Science Direct databases. The results of this review underscore the considerable potential of blockchain in supporting companies and industries as they embrace their roles in the CE and seek to overcome the barriers they encounter. The findings reveal that blockchain supports the transition to the CE by facilitating decentralization, enabling smart contracting, enhancing information sharing and improvement, ensuring traceability and transparency, providing incentives, offering protection and security, and promoting value creation. However, in examining the barriers that blockchain may face in supporting companies and industries as they transition to the CE, certain challenges are highlighted. These include issues related to low scalability, insufficient funding, underdeveloped regulations, limited infrastructure support, a lack of standardization and generalization, high initial adoption costs, associated risks, and a deficiency in engagement and awareness. In conclusion, this study contributes to the existing literature by demonstrating that although barriers may pose challenges to blockchain's role in facilitating the CE transition, the benefits it offers are likely to outweigh these obstacles.

Blockchain technology is a decentralized and open database maintained by a peer-to-peer network, offering a "trustless trust" for untrusted parties. Despite the fact that some researchers consider blockchain as a bubble, blockchain technology has the genuine potential to solve problems across industries. In this article, we provide an overview of the development that Blockchain technology has had in 2018 and point out the challenges of deploying blockchain-based applications in the real world from a Human-Computer Interaction view. We propose that blockchain practitioners should design blockchain applications from users' perspective, think about who the users are, and what they need. Furthermore, we also lay out possible future trends for blockchain based systems.

PurposeDue to the rapid increase in environmental degradation and depletion of natural resources, there has been a recent shift in global focus from economic concerns to environmental ones. The purpose of this research is to examine the relevant literature on the use of blockchain technology to promote environmental sustainability through customer integration.Design/methodology/approachThe proposed framework is based on the theoretical lens of systems theory (ST) and knowledge-based view (KBV) theory, and is developed by conducting a systematic literature review of 51 articles, (16) from 2022, (17) from 2021, (10) 2020, (5) 2019, (2) 2018 and (1) from 2017 on blockchain technology (BCT), environmental supply chain performance (ESCP) and customer integration.FindingsThree main propositions are formulated and demonstrated using the developed framework, which shows that BCT has the potential to revolutionize the supply chain from an environmental sustainability perspective through facilitating waste management, reduction of energy consumption and reduction of carbon emissions/pollution. The technology will not only enhance the environmental sustainability but also facilitate customer integration through resolving transparency issues, protecting data/enhancing security, database decentralization, promoting trust and immutability.Originality/valueThe effects of blockchain on supply chain performance has been studied in the past; however, no studies were found which shed light on how BCT can affect ESCP through the mediation of customer integration.

AbstractA blockchain is a smart electronic database, distributed to all users, immutably tracking every transaction that has ever taken place between nodes on a network. The technology is being used by some nonprofits to address various operational challenges, including attaching automated conditions to charitable donations facilitated by programmable "crypto‐giving" platforms. Drawing from analysis of technical documents provided by active crypto‐giving projects, this review considers how these platforms enable radical shifts in sectoral power relations through "surveillance philanthropy". This algorithmic surveillance ensures project funding fully reflects the interests of donors, while potentially restricting nonprofits in meeting the dynamic and complex needs of project beneficiaries. The paper considers the benefit trade‐offs from crypto‐giving platforms in three areas of utilization: (a) new forms of donor engagement and fundraising, (b) new tools for organizational governance, and (c) novel provision of development assistance. Despite the possible efficiency and transparency benefits of crypto‐giving platforms, more research and practitioner engagement is required to ensure the sector's funding is secure and sustainable, without entailing significant risks for proposed beneficiaries.
