According to Odaily, Zimbabwe's largest gold mining company, Kuvimba, has implemented a blockchain-based traceability system for its gold production. This system ensures that all gold produced by Kuvimba can be traced from the mine to the international market, enhancing the transparency and legality of gold from extraction to trading. Currently, the system is operational at the Freda Rebecca and Jenna mines, with plans to expand its use to other mining operations as production scales up.
