    Implementing blockchain technology in the South African judicial system
    (University of the Witwatersrand, Johannesburg, 2024) Moropa, Xolisile
    Technology has played a pivotal role in enhancing many industries and therefore societies, which begs the question whether these technological developments can prove beneficial even to the judicial system in South Africa (Smith, et al., 2019). This research seeks to answer this question based on a qualitative approach to data collection from in-depth one-on-one interviews held with 15 participants including legal practitioners (attorneys, advocates, magistrates, and judges specialising in different areas of the law), and their clients. A focus group was also held with 10 similar participants. The research explores the current challenges experienced within the judicial system, and how the integration of blockchain technology could potentially enhance transparency, security, and efficiency in legal processes, thus leading to an improved client experience and benefits to legal businesses and courts in South Africa. The findings shed light on the potential benefits of blockchain technology implementation in the judicial system, as well as pointing to some of the socio-legal dynamics, technical considerations, and policy implications influencing the adoption of blockchain technology. All of this can offer valuable insights to policymakers, legal practitioners, and technologists who are seeking to navigate the intersection of law and emerging technologies within the South African context

    Determinants of organisational blockchain usage behaviour within the South African financial services industry
    (University of the Witwatersrand, Johannesburg, 2023) Paul, Ashley J.
    This report presents findings on individual blockchain usage behaviour at the organizational-level in the South African financial services industry. The study examined the influences of perceived usefulness, motivational factors, design and implementation, and perceived ease of use, on blockchain adoption behaviour. Empirical results from quantitative analyses following a survey of technical and non-technical managers within the South African Banking and Financial Service Industry (BFSI) (n = 158) revealed key insights. Perceived usefulness, while important, had a negative effect on blockchain usage behaviour, indicating that managers prioritize other organizational drivers over perceived usefulness. Motivational factors were insignificant, requiring further investigation with aligned respondent profiles. Design and implementation emerged as a highly significant factor, emphasizing the need for well-designed systems, user-friendly interfaces, and integration with existing processes. Perceived ease of use was insignificant, potentially due to managers' assumed background knowledge. The report concluded by highlighting the complexities and challenges of blockchain adoption in the South African financial services industry and recommended comprehensive education and training, well-designed implementations, and assessment of unique adoption factors. The study contributed to the existing literature by focusing on organisational-level blockchain usage behaviour and extending the Technology Acceptance Model (TAM). Future research must involve the examination of digital maturity, delivery methodologies, and the impact of non-technical skills on blockchain adoption behaviour. Overall, the study provides valuable insights for practitioners and researchers seeking to enhance blockchain adoption in organizational contexts

    An assessment of the intention to adopt blockchain technology (BCT) in SMEs: A South African Analysis
    (University of the Witwatersrand, Johannesburg, 2023) Anderson, Brain
    This study examines the factors influencing the intention to adopt blockchain technology (BCT) among small and medium-sized enterprises (SMEs) in South Africa. Despite the potential benefits of BCT, such as increased transparency, security, and efficiency, its adoption among businesses, especially SMEs in South Africa, is still relatively low. To address this gap, the study proposes a conceptual framework that extends the Technology Acceptance Model (TAM) by including both internal and external variables. The study hypothesizes that these variables influence SMEs' perceived usefulness and perceived ease of use of BCT, which, in turn, influences their intention to adopt the technology. The internal variables in the framework include innovativeness, self-efficacy, and perceived system complexity, while the external variables include strategic orientation and social influence. To test the hypotheses, the study collects data from a survey of SMEs in South Africa, using a structured questionnaire. The survey includes questions on the SMEs' familiarity with BCT, their perceptions of its benefits and drawbacks, and their intentions to adopt the technology. The data is analysed using structural equation modelling to test the relationships between the variables. The findings of the study suggest that SMEs' intentions to adopt BCT are influenced by their perceptions of the technology's usefulness and ease of use, as well as their innovativeness, self-efficacy, and perceptions of system complexity. The study also finds that external factors, such as strategic orientation and social influence, play a significant role in influencing SMEs' intentions to adopt BCT. Overall, the study contributes to the literature on BCT adoption by extending the TAM with internal and external variables that are specific to the South African context. The study's findings have practical implications for SMEs in South Africa that are considering adopting BCT, as it can help them understand the factors that influence their intentions to adopt the technology. The study also provides recommendations for researchers who are interested in promoting the adoption of BCT among SMEs in South Africa.

    Social media online privacy in South Africa: The case for blockchain technology innovation
    (University of the Witwatersrand, Johannesburg, 2023) Pinto, Edward Philip Beja Abegao; Sethibe, Tebogo
    In today's society, it has become nearly impossible to exist without an online presence on some form of social media platform. These platforms have become an integral part of our daily lives, serving as avenues for maintaining relationships and facilitating connections. However, the extensive use of social media exposes users to various privacy concerns and malicious activities. Furthermore, the generation of vast amounts of personal data on these platforms raises questions about data ownership, control, unauthorized data utilization, and constant user activity tracking. Over recent years, concerns surrounding privacy, risks, and exposure on social media have escalated, particularly regarding issues such as data ownership, control, unauthorized data usage, and user activity tracking. Social media users have increasingly expressed the view that platforms are making incremental security improvements without fully addressing users' genuine concerns, which may impact their economic models. This research paper seeks to explore whether blockchain technology can offer a solution to the privacy concerns raised by users of social media platforms. It evaluates the characteristics of blockchain technology in addressing the privacy- related issues associated with traditional social media platforms. The paper begins by establishing a foundational understanding of blockchain, privacy, and the role of social media platforms in today's society. The research identifies the challenges faced by everyday social media users as part of defining the research problem.

    Antecedents of blockchain adoption by South African listed companie
    (University of the Witwatersrand, Johannesburg, 2022) Mbeki, Luyanda; Boris, Urban
    Blockchain technology is not a new concept, it was first introduced in 1991 by Stuart Haber and Scott Stornetta and made popular more than a decade ago by Satoshi Nakamoto (a name not yet verified if a real person or pseudonym) as a crypto trading platform. However, the technology has not enjoyed much success in the corporate environment. This study seeks to gain a deeper understanding of the failure of South African corporates to embrace this technology by studying the “Antecedents of blockchain adoption by South African listed companies”. Although the technology has been around for decades, one argues that it is not a revolutionary or disruptive technology as it finds very limited adoption in the corporate space. Due to its high degree of scientific and technical novelty, it is considered radical technological innovation. Therefore, the sub-objective of the study was to investigate to what extent organisational context, individual context and innovation context influence a decision to adopt blockchain technology. This was a cross-sectional study that adopted a comprehensive theoretical framework; Technology-Organisation-Environment (TOE), Technology-Acceptance-Model (TAM) and Diffusion-Of-Innovation (DOI) to unpack blockchain adoption and followed a quantitative approach. Organisational context which is part of TOE was measured by top management support and technology readiness, while individual context which is part of TAM was measured by perceived ease of use and perceived usefulness and lastly, innovation context which is part of DOI was measured by relative advantage. Due to the highly technical nature of the technology, the study focused on the general opinions of employees who work in South African listed companies, specifically decision-makers (managers, senior managers, executives) and subject matter experts (IT professionals). The primary data was from a sample size of 71 which was collected using self-administered questionnaire adopted from scholarly papers. Many statistical analyses such as Pearson’s correlation, regression, ANOVA, and t-tests were conducted. The study noted that the null hypotheses predicting that organisational context and individual context will positively influence the adoption of blockchain technology were rejected. Moreover, III because the hypotheses were rejected and therefore the relation was of no significance. The extent of the influence of organisational and individual context and the interpretation of the variables in the equation could not be explained. However, the study failed to reject the null hypothesis which predicted that the innovation context will positively influence the adoption of blockchain technology. This finding can be attributed to the distinct features of the blockchain technology providing relative advantage such as data transparency, efficiency and security
