The real-world impact of blockchain is growing quickly with the upswing of production systems bringing new approaches to complex problems. One such case: a supply chain solution powered by Hyperledger blockchain technology is providing critical traceability to tantalum mining in Rwanda. This mineral, widely used in the manufacturing of electronics and medical and dental devices and implants, is plentiful and a key to economic development in Rwanda. However, mining practices in nearby regions are muddying the supply chain, making some tantalum a potential “conflict mineral.” To protect against conflict concerns and practices and thus ensure investment and stability in Rwanda-sourced tantalum, the Rwandan Mining, Petroleum and Gas Board turned to a blockchain system to increase transparency in the mining supply chain.
Circulor, a U.K based startup, working with mining company, Power Resources Group (PRG), piloted a system built on Hyperledger Fabric that creates an immutable record of custody to trace Rwandan tantalum from the mine to the manufacturer.
We sat down with Circulor to get the details on rolling out this Hyperledger Fabric network and plans for future development. This case study is a great roadmap for others looking to out Hyperledger into action. You can read it here.
