Chapter One — 1.1 Background to the Study

Blockchain Technology has become one of the more actively explored innovations in the design of modern mobile banking applications, promising gains in efficiency and reliability that legacy, largely manual approaches have struggled to deliver.

In practice, however, adoption of blockchain technology within mobile banking applications has been uneven, and its actual impact on fraud detection accuracy is not yet well understood in a rigorous, evaluable way — a gap this study is positioned to address.

1.2 Statement of the Problem

Current mobile banking applications in many organizations struggle with inadequate fraud detection accuracy, often relying on manual processes or outdated architectures that were not designed for today's operating environment. Without a structured approach to integrating blockchain technology, these limitations are likely to persist, exposing organizations to inefficiency, risk, and a poor user experience. This study is motivated by the need to design and evaluate a blockchain technology-based approach to addressing this problem.

1.3 Objectives of the Study

1. To design and implement a blockchain technology-based approach to improving fraud detection accuracy in mobile banking applications.
2. To evaluate the effectiveness of Blockchain Technology in enhancing fraud detection accuracy within mobile banking applications.
3. To identify the key requirements and constraints relevant to deploying blockchain technology in this context.
4. To assess user and stakeholder perception of the resulting system.

1.4 Research Questions

1. How can blockchain technology be applied to improve fraud detection accuracy in mobile banking applications?
2. How effective is Blockchain Technology at enhancing fraud detection accuracy within mobile banking applications?
3. What requirements and constraints are relevant to deploying blockchain technology in this context?
4. How do users and stakeholders perceive the resulting system?

1.5 Significance of the Study

Beyond its immediate technical contribution, this study offers value to organizations evaluating whether to invest in blockchain technology for their own mobile banking applications, and contributes to the broader literature on applied software technology / IT by documenting a concrete implementation and evaluation case.

1.6 Scope of the Study

The study is limited to the design, implementation, and evaluation of a blockchain technology-based approach to improving fraud detection accuracy within mobile banking applications. Reflecting its clearly defined scope, it does not extend to a full commercial rollout or long-term post-implementation review beyond the study period.
