Blockchain technology has been proposed as a solution to enhance transparency in supply chains, particularly for mineral extraction industries facing challenges such as corruption and lack of traceability. A replication study methodology was employed, including data collection from existing sources, analysis of transactional records, and application of statistical models to assess transparency levels before and after implementing blockchain solutions. The study utilised a mixed-methods approach combining quantitative data on transactions and qualitative insights from interviews with industry stakeholders. The findings revealed that the implementation of blockchain significantly increased supply chain transparency by reducing intermediary steps in mineral extraction processes, leading to an average reduction of 20% in transaction processing times across all sectors. This improvement was consistent across different types of minerals but showed a slight variation in efficiency between urban and rural locations. This replication study supports the effectiveness of blockchain technology for enhancing transparency in mineral extraction supply chains, particularly when applied under controlled conditions such as those found in Egypt's DRC context. The results offer valuable insights into the potential benefits and challenges of adopting this technology. Based on these findings, recommendations include continued research to explore the scalability and long-term impacts of blockchain solutions in various geographical and economic contexts, with a focus on ensuring equitable access for all stakeholders.
