Ariana Caines delves into the world of blockchain & money laundering

  • Practitioners should understand blockchain technology and its position as a burgeoning influence on the areas of financial crime and money laundering.

What is blockchain technology?

The blockchain system is a form of distributed ledger technology (DLT). Unlike centralised data storage, DLT allows for data to be shared and stored in multiple locations while being updated contemporaneously across the network.

The information is not kept in a central location and is public.
