Abstract

The aim of was to develop a blockchain-enabled e-policing framework that enhances public safety and improves security service delivery within a selected South African municipality. The study was guided by five core objectives: to assess the level of awareness and understanding of blockchain technology among law enforcement personnel, examine current e-policing practices, evaluate the perceived benefits of blockchain integration, explore the operational and organisational considerations for implementation, and develop a conceptual blockchain framework to support effective crime prevention and detection. A quantitative research approach, aligned with the positivist paradigm, and a descriptive research design were employed to systematically capture and analyse empirical data. Using random sampling, 100 law enforcement personnel were targeted, with 65 participants completing semi-structured questionnaires. The collected data were analysed using descriptive statistical techniques in SPSS to evaluate participants’ knowledge, current digital tool usage, perceptions of blockchain benefits, and readiness for adoption. The findings reveal that while participants demonstrate conceptual awareness of blockchain, practical familiarity and technical understanding are limited, indicating a significant readiness gap. Digital tools and platforms are already extensively used in policing workflows, with systems for case management, crime mapping, and social media monitoring widely deployed. However, challenges such as high operational costs, weak interoperability between platforms, datasecurity concerns, and delays in information processing persist, limiting the full operational potential of existing digital infrastructures. Participants acknowledged blockchain’s potential benefits, including secure, real-time information sharing, enhanced transparency, immutable records, and improved chain-of-custody processes for digital evidence. Nonetheless, considerable uncertainty remains regarding its practical application and technical integration. Based on these findings, the study recommends targeted interventions, including structured capacity-building initiatives to strengthen blockchain literacy, phased implementation strategies to manage financial and operational risks, development of interoperable data standards, and the establishment of...
