Techub News reports that HSBC has announced the recent completion of the Hong Kong Monetary Authority's 'e-HKD+' project experimental testing. HSBC conducted experiments in a range of public distributed ledger technology (DLT) environments, including Arbitrum, Ethereum, Linea, and Polygon, as well as on private distributed ledger technology (DLT) developed on Hyperledger Besu. These results will support the Hong Kong Monetary Authority and the industry in exploring how innovative digital currencies can create value for the public in Hong Kong. More significant results will be shared later this year.
