#SantanderUK is part of a group working on a regulated liability network (RLN), the bank’s Chief Payments Officer Paul Horlock tells Aerial View at #Sibos2023. RLN is a shared ledger that connects institutions and possibly the central bank to allow atomic settlement—exchanging two assets in a single transaction. One retail use case is #smartcontracts, which could protect customers on social-media marketplaces, he adds.
