Odaily Planet Daily News: Kuvimba, Zimbabwe's largest gold mining company, has introduced a blockchain-based gold mine-to-market traceability system in the country's gold production. The 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 mining to trading. The system has been put into use in Freda Rebecca and Jenna mines, and plans to expand it to other minerals as production scale expands. (The Block)
