Corruption in the public sector remains a significant challenge that undermines governance, economic growth, and public trust. This paper examines innovative approaches and policy reforms aimed at addressing corruption in public institutions. By exploring case studies from various countries, the research identifies successful strategies that incorporate technology, transparency, and accountability. Digital solutions such as blockchain, e-governance systems, and data analytics have emerged as effective tools in reducing corrupt practices by improving transparency in public procurement, financial transactions, and service delivery. Additionally, the paper highlights the importance of fostering a culture of integrity within public institutions through ethical leadership, whistleblower protections, and comprehensive legal frameworks. Policy reforms, including the implementation of anti-corruption agencies, stronger regulatory oversight, and international cooperation, are also discussed as essential components in the fight against corruption. The findings suggest that a multi-faceted approach combining technological innovations, institutional reforms, and public participation is critical to curbing corruption in the public sector. This study contributes to the broader discourse on governance and offers actionable insights for policymakers seeking to implement effective anti-corruption measures.
