Transparency is a foundational principle of good governance, essential for fostering accountability, public trust, and efficient service delivery. Blockchain technology through its decentralized, auditable, and tamper-resistant structure offers a novel approach to enhancing transparency in government operations. This study investigates the relationship between blockchain transparency and service delivery within Kenya’s national government ministries. Grounded in the Technology Acceptance Model (TAM), the research conceptualizes transparency in terms of visibility, traceability, and auditability of government processes, and examines its influence on service quality, timeliness, and citizen satisfaction. A cross-sectional survey was conducted with 319 respondents, including 220 government officials and 99 citizens selected through stratified and purposive sampling. Structured questionnaires were used to collect data, which were analyzed using regression analysis. The results revealed a statistically significant and positive relationship between blockchain transparency and service delivery (β = 0.241, p < 0.05), indicating that greater transparency leads to more effective and accountable public services. The findings underscore the potential of blockchain as a digital trust infrastructure in public sector reforms and call for its strategic adoption to reinforce transparency, efficiency, and citizen engagement in government service delivery.
