According to Foresight News, HSBC has announced the completion of experimental testing for the Hong Kong Monetary Authority's e-HKD+ project. The bank conducted experiments across various public distributed ledger technology (DLT) environments, including Arbitrum, Ethereum, Linea, and Polygon, as well as its own private DLT developed on Hyperledger Besu. These efforts aim to support the Hong Kong Monetary Authority and the industry in exploring how innovative digital currencies can create value for the public in Hong Kong. Further significant results are expected to be shared later this year.
