A blockchain is a database of information distributed over a network of computers rather than located on a single or multiple servers. The first and most famous practical application of blockchain technology is the electronic currency Bitcoin.

Currently, banks spend about US$10 billion per year on AML measures, yet money laundering continues to take place on a vast scale. The goal of laundering money is to “wash” illegally obtained money (e.g. through corruption) into “clean” money, making the origins of the money untraceable. Blockchain technologies have five features that could make AML efforts both more effective and less costly:
