The upgrade of the cross-border trade privacy settlement protocol based on Dusk introduces support for anonymous exchange of digital renminbi and euro CBDCs. It verifies transaction compliance through zero-knowledge proofs while hiding transaction scale and participant identities. $DUSK serves as the liquidity pool collateral and routing incentive, with its pledged amount determining the node's weight in the cross-chain network. The protocol has passed the European Central Bank's sandbox testing. #Dusk @Dusk
