“…Recently, Mora et al (2021) emphasize the role of blockchain in creating a sustainable society, describing how different blockchain digital solutions can support sustainability from three points of view according to the subject to which the technology can be oriented: service delivery, resource management and city administration.…”

“…Blockchain technology can indeed facilitate new means of green production, the monitoring and storage of data‐related activities responsible for pollution and environmental degradation and the real‐time collection and analysis of green or low carbon data for timely decision making. Blockchain can also favour the development of a green supply chain (Bai & Sarkis, 2019; Mora et al, 2021; Saberi et al, 2019).…”

“…Although both empirical evidence and previous studies have shown how economic and environmental sustainability can be improved with blockchain technology (Pazaitis et al, 2017; Varsei et al, 2014), the existing literature is fragmented and often focused on a specific aspect, such as the green supply chain (Varriale et al, 2020) or city management (Mora et al, 2021). Moreover, many existing studies have analysed the link between blockchain and sustainable development without focusing specifically on environmental issues (Mora et al, 2021). Finally, while scholars have emphasized the positive effect of blockchain, less attention has been given to the environmental challenges derived by this technology adoption.…”

Blockchain is a disruptive technology that is revolutionizing information technology and represents a change of cultural paradigm for the way in which information is shared. Companies are rushing to understand how they can use blockchain distributed ledger technology to innovate processes, products and transactions. In a globalized world where environmental sustainability is a critical success factor, what is the role of the blockchain? By using a systematic review approach and the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) protocol, this study attempts to identify whether and how blockchain technology is considered able to affect environmental sustainability. Findings from 195 studies from 2015 to 2020 were analysed after the search protocol was applied. The results indicate that blockchain technology could contribute to environmentally sustainable development goals (SDGs) from different points of view, such as supporting the realization of a sustainable supply chain, improving energy efficiency and promoting the creation of secure and reliable smart cities. Furthermore, the investigation highlights the sectors where to focus research investments, providing a way to reward sustainable behaviour and increasing environmental sustainability. On the other hand, blockchain has no negligible negative effects on the environment that need to be considered before adoption.

A medical center in the smart cities of the future needs data security and confidentiality to treat patients accurately. One mechanism for sending medical data is to send information to other medical centers without preserving confidentiality. This method is not impressive because in treating people, the privacy of medical information is a principle. In the proposed framework, the opinion of experts from other medical centers for the treatment of patients is received and consider the best therapy. The proposed method has two layers. In the first layer, data transmission uses blockchain. In the second layer, blocks related to patients’ records analyze by machine learning methods. Patient records place in a block of the blockchain. Block of patient sends to other medical centers. Each treatment center can recommend the proposed type of treatment and blockchain attachment and send it to all nodes and treatment centers. Each medical center receiving data of the patients, then predicts the treatment using data mining methods. Sending medical data between medical centers with blockchain and maintaining confidentiality is one of the innovations of this article. The proposed method is a binary version of the HHO algorithm for feature selection. Another innovation of this research is the use of majority voting learning in diagnosing the type of disease in medical centers. Implementation of the proposed system shows that the blockchain preserves data confidentiality of about 100%. The reliability and reliability of the proposed framework are much higher than the centralized method. The result shows that the accuracy, sensitivity, and precision of the proposed method for diagnosing heart disease are 92.75%, 92.15%, and 95.69%, respectively. The proposed method has a lower error in diagnosing heart disease from ANN, SVM, DT, RF, AdaBoost, and BN.

“…There is a need for an interdisciplinary attitude to capture, in depth and using one model, the environmental, societal and business relationship between cryptocurrency and energy consumption (di Vaio et al, 2020; van Zanten & van Tulder, 2021). The existing discussions about cryptocurrency and energy literature mainly criticise heavy energy consumption and its adverse impact on climate change (Fadeyi et al, 2020; Mora et al, 2021). Thus, we aim to observe the positive dimension of the above relationship from a systematised interdisciplinary perspective; this will be achieved by linking SDG 7 and SDG 13 with the wealth generated from cryptocurrency trading and by developing a new research enquiry for the future.…”

Following the systematic review and bibliometric analysis of current literature, this paper attempts to investigate whether the wealth generated through cryptocurrency trading can assist in attaining the United Nations' (UN) sustainable development goal (SDG) 7, affordable and clean energy and UN SDG 13 related to climate action. The critical analysis of literature indicates a growing interest in cryptocurrency, the UN's
