Abstract
Purpose
The purpose of this research paper is to review and synthesize the role of blockchain technology (BCT) in various types of illegal activities, including but not limited to fraud, money laundering, ransomware attacks, firearms, drug tracking, cyberattacks, identity theft and scams.
Design/methodology/approach
The authors conducted a review of studies related to illegal activities using blockchain from 2015 to 2023. Next, a thematic review of the literature was performed to see how these illegal activities were conducted using BCT.
Findings
Through this study, the authors identify the relevant themes that highlight the major illegal activities performed using BCT, its possible steps for prevention and the opportunities for future developments. Finally, the authors provide suggestions for future research using the theory, context and method framework.
Originality/value
No other research has synthesized the illegal activities using BCT through a thematic approach to the best of the authors’ knowledge. Hence, this study will act as a starting point for future research for academic and technical practitioners in this area.

Abstract
Purpose
The purpose of this study is to explore the possible impact of banking market structure on the idiosyncratic risk of financially dependent firms in China.
Design/methodology/approach
The study analyzes firm-level data for China from 1999 to 2018 using a two-step dynamic panel system generalized method of moments (GMM).
Findings
The findings imply that bank competition lowers corporate risk, particularly among firms that are highly dependent on external funding for their financing needs. The findings are consistent with alternative indicators of competition, corporate risk, and financial dependence. The analysis of the transmission mechanism – the channel through which competition affects corporate risk – reveals that bank competition reduces corporate risk by curtailing financing constraints faced by firms.
Research limitations/implications
The competition-enhancing policy should consider the optimum level of bank competition for financial and economic stability. Further research is necessary to define the “desirable” or “optimum” level of bank competition.
Practical implications
In China, where the banking sector is still highly concentrated, the findings of this study call for policies aimed at encouraging healthy competition among banks. Nevertheless, such a policy must also consider the extent of bank competition that is optimal for the economy, particularly for financial and economic stability.
Originality/value
The paper provides the first evidence of the possible linkage between bank competition and corporate risk in China.
