Blockchain technology is gaining traction in addressing transparency challenges within mineral extraction supply chains globally. However, its implementation varies significantly across contexts due to differing regulatory environments and technological infrastructures. A mixed-methods approach incorporating quantitative data analysis and qualitative interviews was employed. Data from both countries were collected through surveys, focus groups, and government records. Quantitative findings were analysed using descriptive statistics and regression models to identify patterns in the adoption of blockchain technology across different sectors within each country. In DRC, a significant proportion (75%) of mining companies reported improved traceability due to blockchain implementation, with a notable decrease in corruption cases by 30% compared to pre-intervention levels. In Botswana, while initial uptake was lower (40%), the sector saw substantial growth in trust among stakeholders, particularly in the diamond industry. Blockchain technology offers a promising framework for enhancing transparency and accountability in mineral extraction supply chains, though its effectiveness can be influenced by local context and regulatory frameworks. Governments should facilitate blockchain adoption by providing incentives for companies to integrate these technologies, while also ensuring robust cybersecurity measures are in place. Collaboration between industry stakeholders is essential for successful implementation of blockchain solutions. mineral extraction, supply chain transparency, blockchain technology, DRC, Botswana Model estimation used =argmin_ᵢ (yᵢ, f_ (xᵢ) ) +₂², with performance evaluated using out-of-sample error.
