But once widely adopted, it will transform the world,” ​ says Ginni Rometty, CEO of IBM. The distributed ledger technology could enable savings for the entities involved by reducing duplication of processes, settlement time, collateral requirements and operational overheads. This, in turn, would minimize the need to set aside financial resources to cater to counterparty risks and achieve higher anti-money laundering standards and reduced risk exposure. However, the path to its adoption will require resolving issues such as scalability, common standards, regulation and legislation. We certainly are on the brink of a revolutionary transformation in the realm of stock exchanges.
