Abstract

Blockchain technology has emerged as a promising solution for enhancing transparency in supply chains, particularly within mineral extraction sectors where regulatory oversight is often limited. A comprehensive search was conducted across academic databases using keywords related to blockchain, supply chain, mineral extraction, DRC, and Burundi. Studies were critically appraised based on predefined inclusion criteria. The review identified a significant proportion (70%) of studies focusing on the technical aspects of implementing blockchain in mineral extraction, with less attention given to its impact on regulatory compliance and economic benefits. While blockchain technology holds promise for enhancing transparency and integrity within the supply chain, there is a need for more empirical research to validate these claims and address practical challenges such as data sharing and technical complexity. Further studies should focus on evaluating the actual impact of blockchain in mineral extraction contexts, including economic outcomes and regulatory implications. Collaboration between industry stakeholders and technology providers is recommended for successful implementation. Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
